NOTE REGARDING THE CHESTER MASTODON. The attention of the Editor has been called to the account of the finding, exhumation and character of the remains of the Chester, N. Y., mastodon ^ which was printed in The American Monthly Magazine and Critical Review, Vol. I, pp. 195, 196, New York, July, 1817. This publication is so rare that the account is reprinted here. LYCEUM OF NATURAL HISTORY. Sitting of June 2. Dr. Mitchill, the president of the Lyceum, and Dr. Townsend, the committee appointed, by a resolve of the society, to visit and explore the tract between the Highlands and the Catskill Mountains, made a report in part; from which report the following is an extract: "It was the good fortune of the commissioners to find another skeleton of that huge creatiue the Elephas Mastodon, which though apparently extinct, was formerly an inhabitant of New- York. This happened on the 27th and 29th of May, upon the farm of Mr. Yelverton, near Chester, a village in the town of Goshen. The soil is a black peat or turf, sufficiently inflammable to be employed for fuel. Its surface is overgrown with grass, forming a luxuriant meadow for grazing. — The herbage and the bottom in which it grows, have a near resemblance to the turf meadow of Newton, in Queen's County, Long Island. The sward and turf covering the skeleton are about 1 Noted with facsimile reproduction of Dr. Townsend's drawing in this Volume, p. 147 PI. V, four feet deep. Beneath these is a stratum of coarse vegetable stems and films, resembling chopped straw or drift stuff, along the sea-shore, about a foot and a half thick; and under this is a stratum of fine bluish and soft clay. Specimens of these are brought away, and are herewith presented. The bones raised were parts of a lower jaw with its teeth, of a scapula, of a humerus, of an ulna and radius, of the bones of the feet, of ribs, and of vertebrae. The upper maxillary bone was found, with its grinders and tusks, in their natural situation. Dr. Townsend and Dr. Seely, who had from the beginning aided with their own hands the acquisition of these curious remains, now laboured with the greatest assiduity in the pit to uncover com- pletely, and elevate connectedly, these important parts of the animal. The unparal- leled association of bones, teeth, and ivory prongs, were, after much exertion, de- nuded of their mud and developed to view. They lay upside down, or, in other words, their natural position was inverted, as if the creature had died in a supine posture. The palate bones were perfectly in sight, with the huge molares on each side. From the point forward where the palate joins the upper maxillary bone in other animals, two ivory tusks proceeded. These were not inserted in sockets; at least no such holes or sockets could be found ; but they seemed to be formed by a gradual change of bone to ivory, or of osseous to eburneous matter. In this lespect the conversion resembled the jaw and tooth of the Saurian reptile of Nevesink, al- ready in the cabinet of the Professor of Natural History ; in w^hich organization the jaw is converted gradually to tooth. Their direction was forward, with a bold curva- ture outward and upward. Between the tusks could be seen and felt the nasal proc- esses to which the proboscis had formerly been attached. They were short and ungular. On attempting to loosen the left tusk from its clayey bed, it broke across, though touched in the most delicate manner. Though approached with the gentlest touch, it flaked off in considerable portions, and cracked through in several other places. Finding it wholly impossible to preserve its entirety, recourse was had to measuring the relics as they lay, and of making drawings from them as accurately as possible. And as the fragments of the tusk were handed up. Dr. Mitchill measured them by a rule, and found their amount, reckoning within bounds, to be eight feet and nine inches; or taking into calculation the space of connexion with the jaw as being three inches, or perhaps more, the length of the tusk was nine feet, or upwards, of solid ivory* The circumference at the base was two feet and two inches, making a diameter of eight inches and two- thirds! The taper was easy, gradual, and smooth, like the tusks of other elephants. Dr. Townsend made a sketch of the parts in situ, before they were removed; by which it will be seen how the grinders are situated in relation to the tusks, and how tusks are to be considered as holding a middle place, in their anatomical structure and use, between teeth and horns. The various parts of the animal which were disinterred, and the drawings and illustrations, are herewith submitted to the society. " Although the fragile and friable nature of these bones might render it impossible ever to connect them into a complete skeleton, the commissioners state it as a matter of the highest probability, that at the aforesaid place, the remainder of a mammoth, as huge perhaps as ever walked the earth, reposes in the swamp, not more than fifty-four miles from the site of this institution. — He has already heard the resusci- tating voice of the Lyceum." * The tusks, though solid, are changed in their nature. Professor MacNeven, honorary member of the Lyceum, mentioned, in the society, that he had found their substance to be converted into carbonate of hme. vl VOL.

LIBRARY NEW YORK BOTANICAL QARUEN. By Edmund Otis Hovey, Recording Secretary. On May 23, 1907, the New York Academy of Sciences, in common with many other scientific societies and institutions throughout the world cele- brated the two hundredth anniversary of the great Swedish naturalist Carl von Linne, who is better knov^Ti perhaps by his Latin name Linnaeus. In preparation for the event, the following invitation was sent out to sister societies throughout the world and to the Honorary Members of the Academv. The New York Academy of Sciences will celebrate on May 23, 1907, the Two Hundredth Anniversary of the Birth of Carl von Linne. At this time, commemorative exercises will be held at The American Museimi of Natural History, The New York Zoological Park, The New York Botanical Garden, The New York Aquarium, The Brooklyn Institute of Arts and Sciences.

"To the proofs of this proposition," he continues, "I request those who are my auditors to lend a favorable ear and willing attention. "Our holy Faith instructs us to believe that the Divinity created a single pair of the human kind, one individual male, the other female. The sacred writing of Moses acquaint us that they were placed in the Garden of Eden, and that Adam there gave names to every species of animal, God causing them to appear before him. "By a sexual pair I mean one male and one female in every species where the individuals differ in sex." — J. F. Brand's translation, in Select Dissertations from the Amoenitates Aca- demicce, 1781, pp. 75, 76. 20 ANNALS NEW YORK ACADEMY OF SCIENCES The following address was prepared for the celebration, but was read only by title.

BICENTENARY OF LINNMUS 21 LINN^US AS AN INTERMEDIARY BETWEEN ANCIENT AND MODERN ZOOLOGY; HIS VIEWS ON THE CLASS MAMMALIA. By W. K. Gregory, M. A. In connection Avith the two hundredth anniversary of the birth of Carl von Linn6, or Carolus Linnaeus, it may not be inappropriate to consider him in his capacity of bridging over the gap between ancient and medieval zoology on the one hand and modern zoology on the other, and further to glance at the principles and facts upon which he based his two great con- tributions to the broader knowledge of the class of which man is the domi- nating member. For this purpose the history of zoology may be divided, in a general way, into seven epochs: the Aristotelian, the Scholastic, the Renaissance, the Raian, the Linnaean, the Cuvierian, and the Darwinian. There are also two axioms which it will be well to bear in mind. The first is, that Linnaeus became a point of departure in the history of modem biology, only because he was in turn the product of the intersection of many important historical series which ramify and intertwine indefinitely, and stretch back into the remote past of every aspect of life. The second axiom is, that every new idea, or, for that matter, every new event, is the fertile hybrid resulting from the fortuitous crossing of several specifically distinct old ideas or events. The Aristotelian Epoch. The first epoch under consideration is that of Aristotle, of the fourth century B.C., and it may be characterized as the initial analytical epoch. Aristotle's theory of the genetic relationship of the chain of beings from polyp to man did not, of course, materially influence Linnaeus. The idea of evolution was not destined to come to its fruition through Aristotle, the schoolmen, or even in Linnaeus or Cuvier. The true relation of Aristotle as a systematic zoologist to Ray and Linnaeus is exhibited in the following well-known citations from "The Parts of Animals." " Some animals are viviparous, some oviparous, some vermiparous. The vivipa- rous are such as man and the horse, and all those animals which haA'^e hair; and of the aquatic animals, the whale kind, as the dolphin and cartilaginous fishes fin refer- ence to the viviparity of certain sharks] (Book I, Chap. V). Of quadnipeds which have blood and are viviparous, some are (as to their extremities) many-cloven, as the hands and feet of man. For some are many-toed, as the lion, the dog, the panther; some are bifid, and have hoofs instead of nails, as the sheep, the goat, the elephant. 22 ANNALS NEW YORK ACADEMY OF SCIENCES the hippopotamus; and some have undivided feet, as the solid-hoofed animals, the horae and ass. The swine kind share both characters [an allusion to the 'mule footed' swine, monstrosities in which the median digits are fused, and terminate in a soUd composite hoof]" (Book II, Chap. V). Ray and later writers probably had this passage in mind when they used the descriptive terms "multifido," "bifido," "solidungula," "ungulata," "unguiculata," fissipedes." Here, also, attention is directed to the feet as exhibiting characteristic differences. In another passage Aristotle says, — " Animals have also great differences in the teeth both when compared with each other and with man. For all quadrupeds which have blood and are \i\iparous have teeth. And in the first place some are ambidentaP (having teeth in both jaws); and some are not so, wanting the front teeth in the upper jaw. Some have neither front teeth nor horns, as the camel; some have tusks,^ as the boar; some have not. Some have serrated teeth,^ as the lion, the panther, the dog; some have the teeth unvaried,^ as the horse and the ox; for the animals which vary their cutting teeth have all serrated teeth. No animal has both tusks and horns; nor has any animal with serrated teeth either of those weapons. The greater part have the front teeth cutting, and those within broad " (Book I, Chap. II). This passage evidently directed the attention of later writers to the importance of the teeth as a means of distinguishing and hence of classi- fying mammals, and we shall see that Ray and, later, Linnaeus were quick to avail themselves of the suggestion. Aristotle was quite unconscious of the classification that has been ascribed to him, as Whewell ^ shows; but "Aristotle does show, as far as could be done at bis time, a perception of the need of groups and of names of groups in the study of the animal kingdom, and thus may justly be held up as the great figure in the prelude to the formation of systems which took place in more advanced scientific times." Wbewell also quotes passages that show Aristotle's recognition of the lack »f generic names to denominate natural groups. Aristotle says that "of the class of viviparous quadrupeds there are many genera,^ but these again are without names, except specific names, such as man, lion, stag, horse, dog and the like. Yet there is a genus of animals that have manes, as the horse, the ass, the oreus, the ginnus, the innits and the animal which in S}Tia is called keminus (mule) . . . Where- fore," he adds (that is, because we do not possess genera and generic names of this kind), "we must take the species separately and study the nature of each." "These fassacjes" Whewell continues, "afford us sufficient ground ' A|X({>o8ovTa. - XavXto'Sovra. ' Kapxopo'SovTa. * AvtTroXXaKTa. « Op. cU.. III., p. 350. * EiST]. BICENTENARY OF LINNAEUS 23 for placing Aristotle at the Jwad of those naturalists to whom the first views of the necessity of a zoological system are due" (Op. cit., p. 352). The Scholastic Epoch. From the time of Aristotle and his classical successors until the rise of scholasticism in the eleventh centur}^, Europe, as every one knows, was too much preoccupied with world-wide displacements and readjustments of peoples and of institutions to pay particular attention to natural science; and even the Scholastic Epoch in the history of philosophy and science was chiefly occupied with the further development and systematization of the great body of religious and metaphysical doctrines. So far as natural history is concerned, it is perhaps rather a further interregnum than an epoch, rather an era or lapse of uneventful time than a time of the slow ascension of some great illuminative idea. The anthropocentric idea domi- nated in natural history as the geocentric idea dominated in astronomy; hence a knowledge of the real or supposed properties of animals and particularly of plants was chiefly cultivated in connection with alchemy, magic and materia medica. The medieval imagination, full of mysticism, eager for the uncanny ^nd fantastic and teeming with images of ubiquitous devils, flourished on the marvelous tales of a "Sir John Maundeville," and peopled the earth with the monsters w^hich so long sur^^ved and ramped in the Terrse Incognitse of world maps. In the schools, citations from authorities were accepted in lieu of proof, and the simple zoology of Aristotle and the scriptures was deeply covered by the accretions of learned exegesis. Scholasticism reached its prime as early as the thirteenth century, in the system of the illustrious St. Thomas Aquinas, the "princeps scholasticorum." Afterward, while the renaissance movement was discovering new worlds in all directions, scholasticism in general (but with some brilliant exceptions) rapidly reached the "phylogerontic stage" of its evolution, and produced all sorts of bizarre specializations in terminology and in dialectics. It has been said of the scholastic philosophy that it "vigorously exercised the understanding without bringing it to any conclusions." However this may be, it cannot be doubted that the very' excesses of scholasticism stim- ulated the reactive return to experience, which gave rise incidentally to biological science. The schoolmen furthermore perpetuated and aroused interest in Aristotle's analyses, and gave currency to many methods of analysis and description. Among these we may cite, first, the dichotomous method of division, which is a forerunner of modern classifications; second, the logical concepts of genus and species. Especially noteworthy was the expansion of classical Latin into a highly specialized language of philosophy and science. 24 ANNALS NEW YORK ACADEMY OF SCIENCES The Renaissance Epoch. Biological science, and especially zoology, did not respond fully to the impulse of the Renaissance movement until literature, politics, astronomy and geographical discovery had made the most signal advances. Hence in Aldrovandi (1522-1605) and Gesner (1516-65) the superstitions and myths of the middle ages still linger, while the systematic work of future genera- tions is initiated in the extensive illustrated catalogues and descriptions of plants and animals. On the philosophical side of zoology, the Englishman Wotton, in his "De Differentiis Animalium" (Paris, 1552), "rejected the legendary and fantastic accretions [of medieval zoology] and returned to Aristotle and the observation of nature" (Lankester^). One of the con- temporaries of Gesner and Wotton was the founder of anatomy, Andreas Vesalius (1514-64), who boldly broke with tradition, and declared that the source of knowledge of the human body should be, not Galen, but the human body itself. Near the end of this period, the botanist, Cesalpino (Csesalpinus) of Arezzo (1519-1778), a celebrated scholastic pliilosopher, published his volu- minous work "De Plantis" (1583). In this work, which was inspired by the new idea of direct observation, the confused arrangements of plants of the earlier herbalists were replaced by an orderly classification suggested by the brigades of an army, and founded upon the number, the position and the figure of the reproductive parts. He divided plants into ten great classes, which were again subdivided; to these assemblages he gave mono- mial names in substantive form. Linnseus himself says of him, that, "though the first in attempting to form natural orders, he observed as many as the most successful later writers" (Whewell, Op. cit., pp. 282, 283). A reason for this precocious development of a natural classification of plants may be sought in the very multiplicity of kinds and the large herbaria and horticultural gardens in existence, which necessitated some sort of orderly arrangement and which would assist the eager student to recognize related series. We note in contrast the delayed progress of the classification of the mammals due to the comparative fewness of known forms, the greater complexity of organization and the difficulties of observation. The Raian Epoch, the Dawn of Modern Zoology. Among tho.se who contributed the data for Linnjeus's generalizations, no name is more important, at least in the history of vertebrate zoology, than ' E. Ray Lankester, The History and Scope of Zoology, In The Advancement of Science London, 1890, p. 293. BICENTENARY OF LINN^US 25 that of John Ray. Accordingly, the fourth epoch under consideration may be termed the Raian Epoch, and culminates with the publication in 1693 of Ray's "Synopsis Methodica Animalium Quadrupedum et Serpentini G^eneris," which is one of the great landmarks in the history of classification. Ray's debt to the past is shown in the facts that his lucid tabular analyses of the common structural features of animals are arranged dichotomously; that in each division and subdivision a single adjective or adjectival phrase indicates the most important common feature of the animals in question, and that these terms are, as we have seen, in many cases borrowed from Aristotle. Ray, like Linnaeus, gave more attention to plants than to animals, and depended upon his colleague, Willughby, for much of the data, especially in the fishes. Like Linneeus also, Ray had a superb gift of order and a philosophical mind that made him a worthy countryman and contemporary of Sir Isaac Newton. In his tabular analysis, Ray distinctly foreshadows Linnaeus in the fol- lowing points : — 1. The higher vertebrates are contrasted with the fishes as breathing by lungs instead of gills. 2. The whales are classed with the viviparous animals and expressly removed from the fishes, from which they were further distinguished by the horizontality of the tail-fin. This step, however, was felt to be so radical that Ray afterwards constructed a definition which included both whales and fishes. 3. As remarked by Gill, the terrestrial or quadruped mammals are bracketed with the aquatic as "Vivipara," and contrasted with the "Ovi- para" or " Aves." "The Vivipara are exactly co-extensive with Mammalia, but the word ' vivipara ' was used as an adjective and not as a novm. " ' This distinction seems to have been an important one, when substance was so carefully distinguished from attribute. Ray emphasized the common attributes of all the terrestrial hairy quadrupeds, of the amphibious hairy animals such as the seals and manati, and of the purely aquatic and fish-like Cetaceans; but he does not seem to have insisted that all these animals agreed in essence and substance as well as in attribute, so that they should require a new substantive name such as Linnaeus afterward applied to them. 4. The double ventricle is noted as characteristic of both Vivipara and Ovipara. 5. In order to associate the "manati" and other amphibious mammals with their terrestrial congeners, the term "hairj- animals" is employed as more comprehensive than quadrupeds. 1 The Story of a Word Mammal, in Popular Science Monthly, Vol. LXI. September, 1902, pp. 43*-438. 26 ANNALS NEW YORK ACADEMY OF SCIENCES Ray further set the standard for Linnseus in his concise descriptions of European and foreign mammals, especially those described by travelers in America and in the East. Ray often used the term "species" merely as the equivalent of the middle English "spece," which survives in our word spice," and meant "kind:" it was also equivalent to the logical "species" (c/. the Greek etSos) of the schoolmen, and is exemplified in Ray and Wil- lughby's "Historia Piscium" in such phrases as "clarias niloticus Belonii mustelse fluviatilis species," "bagre piscis barbatiac aculeati species." But Ray also used the term " species " in quite a Linnsean manner, as in the names Ovis laticauda, Ovis strepsiceros and Ovis domestica. In form, at least, this foreshadows the binomial system of nomenclature and the recognition of the species in general as a supposedly objective reality and the unit of classifi- cation. The form of Ray's specific definitions seems, however, to imply that the term "species" in Ray's mind was often more a "differentia," or specific adjective modifying the generic concept than a fully developed substantive name, and Ray did not apparently realize the convenience of applying the binomial method of nomenclature universally. Even Linnaeus at first intro- duced the specific, "trivial," or common name, merely as a marginal index or symbol of the full specific phrase. Ray recognized the considerable variability of species, but believed also in their separate creation and fixity. He frequently adverts to the internal characters of animals; and his book shows, that even by his time a considerable number of observations on the soft parts of animals had already accumulated. The Linn^an Epoch. The work of Ray in botany and zoology fully prepared the way for Linnseus, whose epoch may be characterized as the Legislative Epoch, be- cause his methods of description and classification, and especially his nomen- clature exerted such profound formative and regulative influence upon the work of his contemporaries and successors that he was called the " lawgiver of natural history." LinncBUs's Broader Contributions to tJie Class Mammalia. One of the most enduring claims of Linnseus upon the grateful memory of posterity arises from his felicitous coinage of the word "mammalia" (animals with mammae or breasts after analogy with Latin words like ani- mal ^) as a class name for the forms characterized by Ray as "viviparous hairy animals." Thus not only the terrestrial hairy oviparous quadrupeds, I Theodore Gill, /. c. BICENTENARY OF LINN^US 27 but also the aquatic Vivipara now called Cetaceans and Sirenians, were for the first time definitely included under a single class name. In attempting to appraise Linnseus's contributions to the broader loiowl- edge of the class of mammals, we must bear in mind what Dr. J. A. Allen has well shown/ namely: that Linnaeus was primarily a botanist, that his interest in mammals was incidental, that his opportunities for studying them were very limited, that his first-hand knowledge of extra-European mammals was practically nil, and finally that several of his ordinal group- ings of mammals (e. g., rhinoceros with the rodents) now appear highly unnatural and even ludicrous. On the other hand, there are certain considerations which may prevent us from thinking any the less of his judgment and genius on that account. Although Linnaeus may have known very little about extra-European mammals, he had, nevertheless, a fairly good conception of the essential features of mammals as a class, as shown by his definition in the tenth edition of the "Systema Naturae" (1758). Here in concise phrase he states that mammals have a heart with two auricles and two ventricles, with hot red blood; that the lungs breathe rhythmically; that the jaws are slung as in other vertebrates, but "covered," i. e., with flesh, as opposed to the "naked" jaws of birds; that the penis is intromittent ; that the females are viviparous, and secrete and give milk; that the means of perception are the tongue, nose, eyes, ears and the sense of touch; that the integument is provided with hairs, which are sparse in tropical and still fewer in aquatic mammals; that the body is supported on four feet, save in the aquatic forms, in which the hind limbs are said to be coalesced into a tail (the only erroneou.'^ idea in the whole definition). Many of these characters had previously been noticed by Ray in his description of the hairy quadrupeds. It is not impossible, too, that Lin- naeus may have been assisted to the comprehension of the essential features of the mammals through his friendship with Bernard de Jussieu, who is said by Isidore Geoffroy Saint-Hilaire to have induced him to include the Cetaceans in the class Mammalia; and possibly he also owed something to the researches of Klein and Brisson. In spite of all this, Linnaeus's own studies in medicine, in Holland, doubtless made him familiar with the anatomy of at least one mammal, man; and on his journeys through the north of Europe he must have observed many other mammals at close range. Thus was Linnaeus prepared for the clear recognition and emphasis of another fact of far-reaching importance. It was evidently well known that the anatomy of the hairy quadrupeds was similar in plan, if not in detail, » See pp. 9 ff. 28 ANNALS NEW YORK ACADEMY OF SCIENCES to that of man, and we find Descartes (for example, in his "Discourse on Method" Part V., 1637) advising those who wished to understand his theory of the action of the lungs and circulatory system, "to take the trouble of getting dissected in their presence the heart of some large animal pos- sessed of lungs, for this is throughout sujficienily like the human" (ital. mihi). And it was further known that of all animals the monkeys are most nearly like man, both externally and internally. This was asserted by Aristotle and other classical authors, but was fully demonstrated in a carefully pre- pared and illustrated work ^ on the anatomy and appearance of animals from the Jardin du Roi, by a committee of savants of the French Academy, appointed by the Grand Monarch. This work and these important observations may or may not have come under the notice of Linnaeus on the occasion of his visit to Paris in 1738. At any rate, he did not hesitate to follow the logical consequences of these facts, namely, that in a strictly zoological classification, man would be grouped not only in the class Mammalia, but even in the same ordinal divi- sion with the monkeys. Accordingly, in the tenth edition of the Systema the earlier name Anthropomorphse is replaced by Primates, and the genera Homo, Simia, Lemur and Vespertilio, are grouped under that order. The Primates were thus regarded as the chiefs of the hierarchy of terrestrial beings, and consequently, as in nearly all subsequent schemes down to the Darwinian Epoch, head the classified legions of creatures. Linnseus was too often at fault in surmising the generic and ordinal affinities of the species of the lower vertebrates; but this bold allocation of man to the order Primates surely bears the marks of genius, and led the way to the modern generaliza- tion that man is knit by ties of blood kinship to the Primates, and more remotely to the whole organic world. LinnoBus's Princi'ples in his Classification of tlie Mammalia. The diagnostic definition given by Linnaeus of the order Primates may be cited because it rests upon the principles and theories which guided him in classification and which led to his most successful groupings, as well as to his serious blunders. This definition is as follows: — Inferior front teeth iv, parallel, laniariform [canine] teeth solitary [that is, in a single pair above and below]. Mamniie pectoral, one pair. The anterior extremities are hands. The arms are separated by clavicles, the gait usually on all fours ("incessu tetrapodo volgo"). They climb trees and pluck the fruits thereof. » Mgraoires pour servir & I'histoire naturelle des aainiaux, &la Haye, 1715 (4to, 2 vols.), redig^es par Perrault et Dodart. BICENTENARY OF LINNAEUS 29 This definition was clearly insufficient to exclude all extraneous genera from this really natural order; for (1) under Lemur Linnceus included, not only all the then known forms now recognized as the suborder Lerauroidea, but also the "Flying Lemur," Galeopithecus, which properly either forms an order by itself with no near affinities with the Primates, or is at most a suborder of the Cheiroptera; (2) the definition also included " Vespertilio," i. e., the bats, excepting Noctilio, an order more nearly related to the Insecti- vores than to the Primates. Many of the characters selected by Linnaeus for his ordinal diagnoses were of the "adaptive" or superficial kind, which are now known to have been most easily modifiable by changes in the external or internal environ- ment. The reason for this mistake was, that Linnseus regarded the mode of sustenance of a group as one of its most deep-seated attributes and most surely indicative of more or less hidden affinities with other groups. Lin- naeus was constantly searching for natural groups, but he did not realize that the natural affinity of the members of the larger groups was due to descent from common ancestors, just as in the case of members of the same species. An example of his reliance upon sustenance is seen in his defini- tion, in the tenth edition of the Systema, of the order Ferse, the Carnivora of later authors. Here "sustenance by rapine, upon carcasses ravenously snatched" is evidently felt to be connected with "front teeth in both jaws: superior vi, all acute," with "laniariform teeth [canines] solitary," with "claws on the feet acute." One of his dicta in botany was, that a character of great systematic importance in one group may be ver}' variable in another; consequently he did not mention " sustenance " under Bruta, but contented himself with the two characters "front teeth none either above or below" and "gait awkward {incessus meptior)." As this order included the elephant, the manatee, the sloth, the great ant-eater and the scaly ant-eater, it has been ju.stly cited as a grossly unnatural assemblage, and the grouping accounted for by Linngeus's ignorance of the animals composing it. Now it is possible that Linnaeus himself did not regard this assemblage as natural, but merely as a convenient artificial grouping. But I am more disposed to attribute its existence to his habit of searching for hidden affini- ties below the most obvious external differences, as when he placed the seals in the order Ferae, joined the bats with the Primates, the horse and the hippopotamus, the rhinoceros with the Rodents, and the pig with the Insecti- vores (in the order Bestiae). Linnaeus recognized that the ordinal classification of the mammals was a difficult problem, as is shown by the conspicuous changes (not always improvements in our eyes) and redistributions which he made between the 30 ANNALS NEW YORK ACADEMY OF SCIENCES first and "tenth" editions of the Systema and further by the fact that Erx- leben, who revised and extended the Systema (1777), abandoned the ordi- nal divisions entirely and merely listed the genera seriatim. The difficulty of the problem is indicated by the fact that Cuvier, with far better material and more extensive knowledge, was constantly deceived by "adaptive" (or homoplastic) resemblances. Even Cope, who wrote much on homo- plastic and convergent evolution, was himself deceived by the similarities of structure in the marsupial "mole," Notoryctes, and the Cape golden mole, Chrysochloris, an undoubted insectivore. The most "inexcusable" blunder of Linnaeus, that of placing the rhino- ceros with the Rodents under the order "Glircs," may have been due, not to carelessness, but to the fact that the Indian rhinoceros has a single pair of close-set cutting incisors in the upper jaw, which oppose the elongate incisor-like appressed canines of the lower jaw and thus show a superficial approach to the rodent dentition. If Linn^us had known that Hyrax, which Pallas described as a Rodent ("Cavia"), had cheek-teeth like those of Rhinoceros, he doubtless might have felicitated himself upon his supposed astuteness. In brief, Linnaeus, as fully shown by Whewell,^ from his profound and wide botanical knowledge, was acquainted with many natural orders, and strove constantly to recognize others. He knew that a character of great diagnostic and fundamental value in one order may be of slight value in another; he knew that even in a natural order some of the diagnostic and fundamental characters might be absent in certain members otherwise clearly allied to a given series. He knew that a natural series is "natural" because of the totality of its characters, that the "genus makes the character," and not vice versa, a hard doctrine to many of his contemporaries. When Linnaeus had arrived at a conception of any given natural order, he selected certain characters as diagnostic, but not necessarily universal, and constructed professedly artificial or only partly natural keys to his "natural" orders. When Linnaeus turned his attention to the classification of animals, we may believe that he followed the same principles. In this application of the principles gained in one subject to the data of another, we have a good example of the felicitous union of specifically distinct ideas to produce a line of ideas that are new and very fertile. The Eelation of Linnaeus to his Successors.

His dictum was species tot sunt diversce quot diversoB fornix ah initio sunt creates. The resemblances between members of a single species were hence held to be due to descent from an original pair, and the mutual infertility of different species to be the natural penalty of the effort to traverse the gaps established from the beginning. This view was somewhat modified in later editions of the Systema, in which Linnaeus held that "all the species of one genus constituted at first (that is at the Creation) one species, ab initio unam constituerint speciem; they were subsequently multiplied by hybrid generation that is by inter- crossing with other species." ^ The general relation of Linnaeus to his successors may be summarized in a few words. The sixth epoch in the history of zoology extends from the latter part of the eighteenth to the middle of the nineteenth century, and may be called the Anatomical Epoch, because, through the labors of Cuvier and his great English pupil and successor, Richard Owen, the taxonomic studies of the Linnaean school vvcre supplemented by the establishment and great development of the sciences of comparative anatomy and paleontol- ogy. In spite, however, of the improvement and expansion of classification, its bearing upon evolution was not generally perceived. Cuvier's researches in these sciences further extended the dogma of the fixity of species; but Owen, through his broader knowledge, gradually gave up the idea and became an evolutionist, although not a selectionist. The seventh epoch, the Darwinian, in which happily we are living, has seen the overthrow of the traditional doctrine of the fixity of species, and has initiated the re-examination of all morphological phenomena in the light of the doctrine of evolution. These morphological facts are reflected more and more in our evolving classifications, which are the outgrowth of the Linnaean system, and which now aim to express, not only degrees of homo- logical resemblances and differences, but also (secondarily) degrees of genetic kinship. The great " lawgiver of natural history " is thus seen in his proper per- spective in a few at least of the series of historical antecedents and conse- quents which intersected in him, inheriting, as he did on the one hand, the language and general methods of the past and the doctrine of special creation; inheriting on the other hand the new spirit and contributions of Vesalius, Cesalpino, Ray and many others, and building upon this the foundations of modern botany and zoology. * Osborn, H.

Mr. Chairman, Ladies and Gentlemen: I I have been asked to make a short address to you on Linnaeus and his relation to North American botany. That the selection fell on me was not because I was the most able one to deliver such an address, for there are THE TWIN-FLOWER, LINN/EA BOREALIS A plant especially beloved by Linnseua, and dedicated to him by Grono\'ius. many abler men present, but simply because I was born in the same countr}' as Linnaeus. In fact, my grandfather came from the same province of Smaiand and even from a parish adjoining that of Stembrohult. in which my illustrious countryman was born. In the early part of the seventeenth century there lived in Jonsboda, BICENTENARY OF LINNMUS 33 SmS-land, Sweden, a farmer named Ingemar Svenson. He had three children, two sons and one daughter, the grandmother of Linnaeus. On the Jonsboda farm stood a very large linden-tree, so old and with so many traditions that it was regarded by the people as a holy tree. Any damage done to this tree, it was claimed, would surely bring misfortune upon the head of the perpetrator. When the two sons began to study for the ministry, it was natural that they should think of this tree in selecting a family name. They called themselves Tiliander; Tilia is the Latin for the linden or bass- wood, and andros the Greek for man. It may not be amiss to state that at that time the common people of Sweden did not have any family names, and this is true to a certain extent even to-day. A man was known by his given name, the given name of his father with the word son appended, and the place vvhere he lived. The farmer mentioned above was known as Ingemar Svenson from Jonsboda. His father's name was Sven Carlson, and that of his grandfather, Carl Johnson. The names of his two sons would have been Carl and Sven Ingemarson, had they remained in the peasant class, instead of Carl and Sven Tiliander. The daughter married a farmer, Ingemar Bengtson ; and her son's name was Nils Ingemarson, until he entered the "gymnasium." He also was born in Jonsboda, and, when selecting a name, he also naturally turned to the same old linden-tree as his maternal uncles had done. He called him- self Linnaeus. It is remarkable that two of his father's maternal grand- uncles also bore anotlicr Latin form of the same name, viz., Lindelius. Some claim that even this name was derived from the same old linden-tree, but this is scarcelv in accordance with the facts. More likelv it traces its origin from the Linden Farm in Dannas Parish, where their ancestors lived. But what has this genealogy to do with Linnaeus's relation to North American botany? Perhaps nothing directly, but indirectly a great deal; for the circumstances and surroundings under which a man is born and reared to a certain extent make the man. In his younger days, Sven Tiliander was the house-chaplain of Field-Marshal and Admiral- Viscount Henrik Horn, who was for many years Governor of Bremen and Verden, two cities with territory in Germany acquired by Sweden through the Thirty-years War. During his stay in Germany, Tiliander learned to know and love botany and horticulture, and established around Viscount Horn's residence in Bremen a garden which was remarkable for that period. When both returned to Sweden, Tiliander brought with him the choicest plants from this garden and planted them around the parsonage of Pjetteryd Parish, of which he had been appointed rector. Here at Pjetteryd, Nils Linnaeus spent most of his youth, studying in company with his uncle's sons. Later, both as curate at RSshult and as rector at Stenbrohult, he 34 ANNALS NEW YORK ACADEMY OF SCIENCES surrounded the parsonages with gardens in which he grew many rare and interesting plants. In the midst of these, Carl Linnaeus, the famous botanist, was born and reared. Later, while a student at the university, he spent a summer vacation at home in 1732, and made a list of the plants in his father's garden. This list is still to be seen in the Academy of Science at Stockholm. Although defective, the first four classes being unrepresented, it enumerates 224 species. Of these, many were at that time very rare in cultivation. Professor Theodore Fries in his biography of Linnaeus enumer- ates 36 of the rarest of these. Among them we notice six American plants, viz., Rhus Toxicodendron, the poison oak, Mirahilis Jalapa, four-o-clock, Asclepias syriaca, milkweed, Phytolacca decandra, pokeweed, Anteniiaria (now Anaphalis) margaritacea, pearly everlasting, and Solanam tuberosum, the potato. It may be remarked that the cultivation of potatoes was introduced into Sweden about twenty years later. We see from this that Linnaeus had learned to know some American plants even in his early childhood. Carl Linnaeus was born the 13th of May, O.S., 1707, at Rashult, an annex to the parish of Stenbrohult. His father was the curate there; but two years later, at the death of his father-in-law, Samuel Broderson, he became rector and moved to Stenbrohult. In the fall of 1714, Carl Lin- naeus entered the school of Wexio, and graduated from the "gymnasium" in 1727. His parents, especially his mother, wanted him to study for the ministry; but he had no love for theology, nor for metaphysics, nor the classics. He learned Latin tolerably, however, because that language helped him to study the natural sciences. He decided to study medicine, and entered with that view the University of Lund, which was nearest his home, but remained there only one year, learning that there were better facilities at Upsala. At the latter place he soon became acquainted with Professors Rudbeck and Celsius, two of the most prominent scientists of that time, and was allowed to use their libraries. The former, who had many duties to perform, soon asked Linnaeus to give for him the public lectures in botany. The income from these gave Linnaeus means to sup- port himself, and linked him closer to his favorite study. He became acquainted with practically all the plants of the gardens and fields of the whole region around Upsala, and learned all the scientific names given in the books at his disposal. The latter was not an easy matter when we take into consideration the form of scientific names at that period. For example, the most approved name of the common blue-grass that adorns our lawns was, "Gramen pratense paniculatum majus, latiore folio, Poa Theophrasti." Other names of the same grass were, "Gramen vulgo cog7iitum," "Gramen prafen,se BICENTENARY OF LINNAEUS 35 majus vulgatus," and "Gramen alterum et vulgare." In the first publication by Linnaeus, it appears as " Poa spiculis ovatis compressis muticis." I think that Linnseus and his contemporaries had much more cause than we to exclaim, "Those horrible Latin names!" To us the same plant is known as Poa pratensis L., the name adopted by Linnseus in his "Species Plantarum." The lectures given by Linnaeus for Professor Rudbeck became very popular. This was especially the case after his return from his Lapland journey. Some persons, especially Dr. Nils Rosen, became jealous of his success, and induced the university faculty to pass a resolution by which no one who had not taken the corresponding degree was permitted to give university lectures. Linnseus had not yet received his doctor's degree, and hence was debarred. As Holland was offering at that time excellent facilities both in medicine and in botany, and as living expenses were lower there than elsewhere, Linnseus decided to visit that country and take his examinations there. He received his doctor's diploma at Harderwijk, and afterwards went to Leyden, where he became acquainted with three of the greatest botanists of the time, Boerhaave, Burmann and Gronovius. George Cliffort, the wealthy burgomaster of Amsterdam and president of the East India Company, was a great lover of plants, and had a splendid botanical garden at Hartecamp as well as a rich library and herbarium. On the recommendation of Boerhaave, Linnseus became Cliffort's physician, and curator of his collections and garden. Here he lived in luxury, beloved as a son. Cliffort furnished Linnseus with means to publish five of his first books, "Systema Naturse," "Fundamenta Botanica," "Bibliotheca Botanica," "Genera Plantarum" and "Flora Lapponica," the manuscript of which he had brought with him from Sweden. In the first of these, Linnseus presents his system of classification. He divides Nature into three kingdoms,— the mineral, vegetable and animal. In the vegetable kingdom he brings out an altogether new classification, based upon the sexual organs of plants. He divides the kingdom into 24 classes, the first 23 containing the phan- erogams, and the last the cryptogams. In the first 11 classes are included plants which have from 1 to 12 free and practically equal stamens; in the 12th and the 13th, plants with many stamens; in the 14th and 15th, plants with 4 and 6 stamens respectively, of which 2 are decidedly shorter. In the 16th, 17th and 18th classes the stamens are united by their filaments, in the 19th they are united by their anthers, and in the 20th they are adnate to the pistil. In the 21st and 22d the flowers are unisexual, i.e., the stamens and pistils are in different flowers (on the same individual in the 21st and on different individuals in the 22d) ; and the plants of the 23d class have both 36 ANNALS NEW YORK ACADEMY OF SCIENCES unisexual and bisexual flowers. The classes were divided into orders. In the first 13 classes the orders were determined by the number of the pistils; in the 14th and 15th, by the fruit; and in the 16th to 18th and 20th to 23d, by the number and distinctness or union of the stamens. The classi- fication of the 19th class is too complex to enter into here. The 24th class was divided into four orders: Filices, Musci, Algae and Fungi. This system of classification is purely artificial. Linnseus himself re- garded it only as temporary, and expected that it would soon be supplanted by a more rational one, based on natural relationship. The Linnaean system served its purpose, however. It became a means by which it was possible to tabulate every known genus of plants. Before this time there had been no systems at all, or such crude ones as we find even to-day in some popular flower-books, where the plants are classified by the color of their flowers. If the natural systems of DeCandolle, Bentham and Hooker, and Engler and Prantl, are too complicated for popular books, why not go back to the simple system of Linnaeus ? It would at least give a good insight into the structure of the flower instead of the mere color. In his "Genera Plantarum," Linnseus applied this system to all known genera of plants, and gave each of them a concise and plain description. Cliffort had many American plants in his garden, but he sent Linnaeus to England to visit Sir Hans Sloane, Professor Dillenius and Philip Miller, in order to secure American plants grown by them. Both Sloane and Dillenius treated Linnaeus at first with coolness, because he "confounded botany." On his farewell visit to Dillenius, Linnaeus politely asked him what he meant by "confounding botany." Dillenius took from the library the first few pages of Linnseus's own "Genera Plantarum," and showed him where there was written at numerous places "NB." Dillenius stated that all the genera so marked were wrongly described. The first example he pointed out, if I am not mistaken, was Canna, placed by Linnaeus in his first class, which contains plants with but one stamen. Botanists before this time had described it as having three stamens. To settle the dispute they went out into the garden, and the living plant showed that Linnaeus was correct. Dillenius then retained Linnaeus for several days, and found that the older botanists in most cases were at fault and the young Swede correct. From being an opponent, he became a friend, of Linnaeus and let him have all the plants he wanted. After his return to Holland, Linnaeus continued his work in Clifi'ort's garden with renewed zeal, and completed his "Hortus Cliffortianus," a large folio, in which are enumerated and described all the plants found in Cliffort's collections, together with synonyms and citations of nearly all botanical works then in existence. In preparing this work he became BICENTENARY OF LINN^US 37 thoroughly acquainted with almost all the literature referring to American botany, such as Morison's "Plantarum Historia," Plukcnett's "Almagestrum Botanicum" and " Phytographia," Petiver's " Gazophylacium," Sloane's "Jamaica," Plumier's "Plantarum x\mericanarum Genera," "Plantarum Americanarum Fasciculus Primus" and "Filicetum Americanum," Catesby's "Historia Naturalis," and, later, Cornuti's "Canadensium Plantarum Historia." After completing the "Hortus Cliffortianus," Linnaeus returned to Leyden, where he spent some time helping Gronovius with the editing of his "Flora Virginica," based on a large collection of plants collected by Cla\1;on. Here again he came in contact with American plants. Linnaeus then returned to Sweden and became a practicing physician. He was soon appointed professor of medicine at Upsala, but by common agreement he exchanged chairs with Rosen, who held the professorship of botany. He now began work upon the most important book of his life, his "Species Plantarum." In this he tried to include a short description of every known species of plant, together with the most important synonyms and citations. In this book the Linnsean binomial system of nomenclature was used for the first time. Linnaeus was not the first to give plants names, nor was he the first to name genera. Many Latin plant-names had come down from antiquity, while others had been proposed by his predecessors. Men like Tournefort and Micheli had in some cases clearer ideas of genera than Linnaeus himself. Neither was Linnaeus the first one to use binomials. In Cornuti's work on Canadian plants, for example, we find almost as many binomials as polynomials; but it is doubtful if Linnaeus had seen Cornuti's book when he first wrote his "Species Plantarum." He does not cite it in the first edition, but does so in the second. Linnaeus was, however, the first one to use binomials systematically and consistently. Before his time, botanists had recognized genera, and applied to them Latin nouns as names. In order to designate species, they added to these nouns adjective descriptive phrases. These consisted sometimes of a single adjective, as in Quercus alba, the white oak, but more often of a long string of adjectives and adjective modifiers, as in the case of the blue-grass mentioned above. The specific name had hitherto been merely a description modifying the generic name; from this time it became really a name, although a single adjective in form. An illustration of the pre-Linnaean form of plant-names might be had if, instead of "Grace Darling," one should say, "Mr. Darling's beautiful, slender, graceful, blue-eyed girl with long golden curls and rosy cheeks." "Grace" is just as descriptive of the girl as this whole string of adjectives. It may be that "Grace" is not always applicable to the person to whom the name is applied; but this is also often the case with many specific plant- 38 ANNALS NEW YORK ACADEMY OF SCIENCES names. Asclepias syriaca and Rumex Brittanica are American plants, and Rubus deliciosus is one of the least delicious of the raspberry tribe. This invention and strict application of binomial names could not but cause a revolution in botany. Since the appearance of "Species Plantarum" in 1753, it has been possible to pigeon-hole not only genera, but also species, of plants. Before this useful book was printed, Linnaeus had become better ac- quainted with North American plants, and in another way. Baron Bjelke, the vice-president of the Court of Appeals of Finland, had proposed to the Royal Academy of Sciences at Stockholm to send an able man to Iceland and Siberia, countries partly in the same latitude as Sweden, "to make observations, and such collections of seeds and plants as would improve the Swedish husbandry, gardening, manufactures, arts and sciences." Dr. Linnaeus suggested .North America instead, and recommended one of his pupils. Professor Pehr Kalm of Abo, for the proposed expedition. Kalm spent two years in North America, traveling through Pennsylvania, New Jersey, New York and Canada, and making large collections of seeds and plants, which were preserved as living or dried specimens, or as alcoholic material. During his stay at Raccoon, N.J., he discovered our mountain- laurel. The Swedes of Raccoon called it spoon-tree, because the Indians made spoons from its hard wood. Kalm adds in his journal, about this tree, "The English call this tree a laurel, because its leaves resemble those of the Laurocerasus. Linnaeus, conformably to the peculiar friend- ship and goodness which he has honored me with, has pleased to call this tree Kalmia joliis ovalis, corymbis terminalibus, or Kalviia latifolia." Here Linnaeus himself gave an illustration of both the pre-Linnaean and the post- Linnaean nomenclature. Kalm became acquainted with several of the naturalists of this country, C. Colden and his daughter Jane, Bartram and Clayton, and through Kalm a correspondence was established between them and Linnaeus. Linnaeus also corresponded with John Ellis, who resided in the West Indies, and Dr. Gardiner, who botanized in Carolina and Florida. Later he bought a set of plants collected by Patrick Browne in Jamaica, and received a part of the collections made by Jacquin in the West Indies. When the second edition of the "Species Plantarum" appeared, in 1762, Linnaeus knew and had described nearly 1000 plants indigenous to the Unite'd States and Canada. Besides these, he described about 1000 more, natives of the West Indies, Mexico and Central America, and 400 or 500 South American plants. His knowledge of American plants was small compared with what he knew of plants of the Old World. "Codex Lin- nseanus," which enumerates all plants named by Linnaeus, contains not fewer than 8551 species. BICENTENARY OF LINN.EUS 39 Linnseus died Jan. 10, 1778, honored and esteemed by all. Some of his work will doubtless live as long as botany is studied by man. We see from the preceding account that we may consider Linnseus one of our American botanists. Even the little plant which Gronovius dedicated to the Father of Botany, the twin-flower of our woods, with its exquisite perfume and its dainty pink flowers, belongs to a genus essentially North American. The genus Linnoea contains four forms, all closely related. One of these, the original Linnoea borealis, is confined to the mountain regions of northern and central Europe. Linnseus discovered it on his Lapland journey, and it was then considered a very rare plant. Now it seems to be more widely distributed than it was at the time of Linnseus. Perhaps it is of American origin, and has become modified since it transplanted itself on the other side of the ocean. The other three forms are North American. Linnooa americana Forbes, which has usually been confounded with its European cousin, is common in the woods from Labrador to Alaska, and extends in the Rocky Mountains as far south as New Mexico. L. longiflora (Torr.) Howell, is found in the mountains from northern California to Alaska. The fourth form is, as far as I know, undescribed and unnamed. It is with great pleasure that I here propose the following name and descrip- tion for this species. Linnsa serpyUifolia sp. nov. A delicate plant with long creeping stems, 1-4 dm. long, sparingly hirsute; petioles 2-3 mm. long, ciliate; blades broadly oval or round-ovate, 5-8 mm. long, minutely crenulate, obtuse, sparingly hirsute, more or less coriaceous and shining, slightly paler beneath; peduncles 3-5 cm. long, sparingly pubescent and more or less glandular above, 2-flowered; bracts 2-3 mm. long, linear or lance-linear, obtuse; pedicels 5-8 mm. long, glandular- pubescent; hypanthium subglobose, in flower slightly over 1 mm. long, glandular-puberulent, purplish; calyx-lobes 2-2.5 mm. long, linear-subulate; corolla pink, open-funnelform with a very short tube, decidedly oblique, about 6 mm. long and 5 mm. wide. This species differs from L. borealis and L. americana in the very narrow and almost glabrous calyx-lobes. In this respect, it agrees with L. longi- flora; but it is distinguished from that species by the differently shaped corolla and by the leaves, which are broadest at or below the middle, instead of above it. It differs from all three in the smaller size of the flower and of the leaves, and in the indistinct toothing of the latter. Alaska: Cape Nome, 1900, F. E. Blaisdell (Type in herb. N.Y. Bot. Gard,); Kotzebue Sound, .4nioif, 40 ANNALS NEW YORK ACADEMY OF SCIENCES Apparently the same plant has also been collected on the Island of Sachalin by F. Schmidt, but his specimens lack flowers. After Dr. Rydberg's address, Professor H. H. Rusby gave an exhibition of selected lantern slides of flowers of North American plants known to Linnaeus, and then Dr. W. A. Murrill led the party southward from the Museum building, through the Garden, to the Linnseus Bridge, pointing out on the way the following characteristic American trees known to Linnseus. Tulip-tree White ash White elm Sweet-gum Sugarberry Red oak Red maple Flowering dogwood White oak Red cedar Sassafras Hemlock Sweet birch Buttonwood Chestnut-oak White pine Butternut American linden At the Linnseus Bridge over the Bronx River, on Pelham Parkway, Professor N. L. Britton, President of the New York Academy of Sciences, unveiled the bronze tablet commemorative of Linnseus which had been placed there by the Academy with the consent of the Department of Parks of the city of New York, and made the following address. ADDRESS BY THE PRESIDENT OF THE ACADEMY. N. L. Britton, Ph. D. Director-in-chief, New York Botanical Garden. The recognition of the work of famous men is one of the happiest duties of mankind. It stimulates our endeavors and encourages us to make efforts which we would probably not make without their examples before us. To-day we do homage to a distinguished man of science, and the una- nimity with which the scientific societies and institutions of the city of New York join in this tribute is in itself evidence of the value which is placed upon his contributions to natural history. Science has made great progress during the two centuries which have elapsed since the birth of Linmeus. Theories have in large part given place to ascertained facts, or have been replaced by other theories based on more accurate knowledge of natural objects and of natural phenomena. The contributions of science to the welfare, comfort and happiness of mankind, have made present human life widely different from that of two o o > z > a: > c. 'J- o r BICENTENARY OF LINNjEUS 41 hundred years ago; and this amelioration of our condition, and the more general diffusion of knowledge, have been accompanied by a vast improve- ment in morality. The ceremonies of to-day are worthy of the great naturalist whose birth they commemorate. Societies and institutions all over the world join with us in honoring him, and are represented here by delegates, or have trans- mitted documents expressing their appreciation of his life and labors. The public natural science institutions of New York have come to take leading parts in the subjects they teach and illustrate. Public and private philan- thropy have developed them with a rapidity almost phenomenal, for they are all yet in their infancy and on a scale commensurate with the dignity of the metropolis of America. The cordial co-operation of a municipality with public-spirited citizens to build and maintain such institutions for the welfare of the people and of science, finds here in New York its maximum evolution, which has as yet, however, by no means reached its complete development or its maximum usefulness. What will be said of their posi- tion and importance when after fifty years the New York Historical Society opens the tablet which we now place upon this bridge ? And what discov- eries will science have made for the benefit of the human race during this next fifty years ? The selection of this bridge, recently constructed by the Park Depart- ment, as a permanent memorial of Linnseus, is most appropriate. It is situated just outside the New York Zoological Park, with the New York Botanical Garden a short distance to the north, being thus between the two institutions which teach the subjects on which the fame of Linnseus chiefly rests. The suggestion that it be known hereafter as the Linnaean Bridge came from the Director of the American Museum of Natural History. On behalf of the New York Academy of Sciences I now unveil this tablet, and present it to the city of New York, there having been placed in it copies of to-day's program and other documents befitting the occa- sion. After Wennerberg's song, rendered by the American Union of Swedish Singers, "Hear us, Svea," Hon. Joseph I. Berry, Commissioner of Parks of the Borough of the Bronx, in a few fitting words accepted the tablet on behalf of the city of New York, and then delivered the key of the box within the tablet to the New York Historical Society, for preservation till Mav 23, 1957. These ceremonies were followed by the singing, by the chorus, of Lindblad's "Battle Hymn," and then the audience listened to the following two addresses. 42 ANNALS NEW YORK ACADEMY OF SCIENCES ADDRESS BY THE PRESIDENT OF THE AMERICAN SCENIC AND HISTORIC PRESERVATION SOCIETY. George F. Kunz, Ph. D. Linnasus was a great scientist, and the conquests of science have done more to advance the world than wars, which science may yet render im- possible. It was thirty years of scientific research in Germany that gave us artificial indigo. It was pure scientific research that led Moissan, Cowles and Acheson to discover independently an abrasive substance of a hardness between the diamond and the sapphire; and then Moissan by scientific deduction worked out the genesis of the hardest and most fearless of gems, which, though obtained only in the form of powder, was still the diamond. Within the past quarter of a century we have seen air, oxygen and hydrogen liquefied, giving us temperatures absolutely unknown in nature before, and also the electric furnace, giving an extreme heat such as has perhaps never existed, unless it be on the surface of the sun. Jade, the Chinese stone, has been known in China for more than a thousand years. Some believe that it was known to a prehistoric race the existence of which was almost unknown to the Chinese, and whose only records extant are found as we find the evidences left of the mound-builders, who passed away before the advent of the white man in North America. It was not until 1866 that Damour, a scientist, separated jade into two distinct minerals, nephrite and jadeite; and one of those into two varieties, jadeite and chloromelanite — facts unknown to the Chinese, though they apparently knew and understood every tiny fragment they had ever seen of this mineral. It was the scientist who took three red stones belonging to the King of Burmah or to the Emperor of China, and proved to him that one was a ruby, one was a spinel, and the third a tourmaline, and not all rubies, as they had been regarded for a century or more previously. Moses was the first great systematizer, and his original assemblage of the people in tens, hundreds and thousands, is carried out in the military systems of to-day, and is again reflected in our own and in the monetary systems of many of the European nations, and more especially in that indis- pensable and scientific international system of weights and measures, the metric system. It was Alexander who conquered the eastern world, bring- ing back with him much refinement, and possibly also the valuable and industrious silkworm ; and it was he also who discovered that the carrying powers of his camels were doubled if he employed a gold medium of exchange instead of silver. Csesar, in his attempt to conquer the world, did much BICENTENARY OF LINN^US 43 toward the dissemination of education and civilization, from which Rome greatly benefited. Napoleon upturned and readjusted the treasuries of a number of king- doms, duchies, cloisters and churches in Europe; and, even though his regime was attended by frightful loss of life, marked and permanent improve- ment has followed it. But it was La Sage, a scientist, who compiled a great work for Napoleon, from which he learned what noble families had lived in all times, and what campaigns had been fought by the various conquerors; and it was a thorough study of La Sage's work that had much to do with giving Napoleon an idea as to what worlds others had conquered, and what parts of this world were left for him to subdue. It may not be generally known that it was one of our New York scientists, Dr. Melvil Dewey, w^io introduced the card catalogue system of catalo- guing books, which led to the present system of keeping books by the loose- leaf system. It would be easy to mention many who have materially assisted in the advancement and organization of the multifarious affairs of mankind; but the other and lower creations of nature outnumbered mankind many thou- sand times, and the co-ordination of scientific nomenclature covering this vast domain is due to the great Carl von Linne. Until his time, an animal was known as a deer in English, a Hirsh in German, a cerf in French, and by fifty other names in as many different languages. By applying two or three words as a name to every creature that flies in the heavens above, that dwells in the earth beneath or in the waters under the earth, he made it possible for the scientist, whether at the Cape of Good Hope, in Greenland, in New York, or in the Sandwich Islands, to know not only just what living form was referred to, but also to understand immediately to just what genus, class, species or variety, this living organism belongs. The Linnaean system has also greatly aided scientific classification in natural history, which, in connection with medicine, has given us the con- necting link in the science of biology and bacteriology. The Linnaean system compares with the natural history of to-day as alchemy does with chemistry, as astrology and fortune-telling with astronomy and medicine of the present time. It is strange that, as well-planned and admirable and successful as the Linnfean system is when applied to the nomenclature of animate objects, it was absolutely rejected by the then mineralogists and chemists, as the chemical equivalents and the structure are frequently better expressed by a single term than they would be by a binominal system. Had a Linnaean system existed when Adam and Eve were in the Garden of Eden, there would be no dispute to-day as to whether the "apple" which 44 ANNALS NEW YORK ACADEMY OF SCIENCES caused their expulsion from the Garden was the identical kind of apple that has caused so many boys to be driven from gardens and orchards wherein they trespass to-day, or whether it was a pomegranate, an orange, a lemon, or some other fruit of which we have no knowledge. If Noah had known a Linnsean system when he took his animals into the ark, and had so named them, how helpful that would be to us to-day ! There would not be the doubt in the minds of the few who still maintain that evidences of the flood are to be found in fossil remains, since these would belong to those animals that were destroyed at the time of the great flood. We have recorded a history of the past, to-day we have heard much of Linnaeus and his time: let us speak now of the present. For a quarter of a century it has been our pleasure to know one of the most ardent disciples of Linnaeus that has lived in our land ; and had it not been for his untiring zeal, his keen judgment, his constant application, it is a question whether we would be assembled to-day to dedicate this bridge to the memory of Linnaeus. We remember twenty-five years ago when he first appeared before the Academy of Sciences, and it is almost that long ago that he first suggested a botanical garden. The Botanical Garden undoubtedly influenced the Zoological Park, and each successive scientific institution has strengthened the others, so that, as science stands united to-day. New York is perhaps and will long remain one of the leading scientific cities in the country, if not the foremost; and no one more than our esteemed President of the New York Academy of Sciences, and Director of the Botanical Garden, Dr. N. L. Britton, has assisted in the unification and the advancement of our greatest Academy of Sciences. Dr. Britton was the pioneer with the Botanical Garden. Professor Henry Fairfield Osborn, another disciple of Linnaeus, was the pioneer in the Zoological Park, which has been so ably conducted and carried on through that indefatigable worker, Dr. W. T. Hornaday, who brought to his task a world-wide experience of animals, their habitats and their characters. Therefore it seems eminently fitting that this bridge should form a connecting link between these two Siamese Twins, as it were, of botany and zoology in the United States. It is science that gives us this well-ordered Bronx Botanical Garden, which, beautiful as it is, is a living botanical exposition, made possible through the organization of Linnaeus, the energy, industry and intelligence of a Britton, the generosity of the founders and its trustees and the encour- agement of our great city of New York. Although historic sites and buildings may be marked with tablets or with monuments of stones, yet it was Nero who removed the Greek inscription, and placed his own, over the architrave of the Parthenon. In 1881 we were surprised to see some stone-cutters removing from within the laurel wreaths BICENTENARY OF LINN^US 45 on the arches of the bridge across the River Seine the raised letter N placed there by Napoleon III, and a few days later to see them incise the letters R. F. (R6publique Fran9aise) where the N had formerly been. The value of preserving historic sites or commemorating historic events by indestructible means, such as medals or engraving in stone or metal, has always served as a great benefit to those who were to follow. A simple tablet on the summit of the Jura Mountains tells one when, where and how the great Napoleon crossed those mountains. A tablet in Russia relates that Napoleon entered Russia at this point with seven hundred and twenty thousand men, and less than a year later returned with an army of only a hundred and twenty thousand, having lost six hundred thousand. The use of metal and baked tiles for the perpetuation of portraits and historic events forms one of the most feasible and enduring means. It is due to the coins and the medals that have been struck since about the seventh century B.C. that we have an almost unbroken line, for the past twenty-four centuries, of portraits and history; and to Assyrian baked tablets, that wc have some four thousand years of history recorded. There should be a most stringent law, a national law, rigidly enforced, for the punishment of any vandal who destroys, either wantonly or for the purpose of loot, any monument, as, for instance, the Andr^ Monument on the banks of the Hudson and the tablet marking the Slocum disaster. It is the honor and pleasure of the American Scenic and Historic Preser- vation Society to take part in this historic event, and it is its official function to describe accurately the event in its Annual Report edited by our able Secretary, Edward Hagaman Hall, and published by order of the Legislature of this State. So the record of this event will appear in series with that of the dedication of Stony Point as a park; the re-dedication of the Andr6 Monument; the preservation of the Palisades; the McGowan's Pass tablet; more recently the acceptance of the gift of three miles of one of the most beautiful ravines on the continent, containing three fine waterfalls, presented to our State by the Honorable William Pryor Letchworth, for which the Society is to act as a Trustee ; and the State's acquisition of Watkins Glen. 46 ANNALS NEW YORK ACADEMY OF SCIENCES ADDRESS BY THE PRESIDENT OF THE UNITED SWEDISH SOCIETIES OF NEW YORK. Emil F. Johnson. I do not intend to encroach upon your time by attempting to make a long speech, but I consider it my duty as president of the United Swedish Societies to express to you, Mr. President, and to the members of the New York Academy of Sciences, our gratitude for the opj)ortunity you have given us to take part in honoring the memory of our distinguished country- man Linnseus, whom we are used to call the "Flower King of the North." To be sure, our participation in this celebration is limited to the assistance given by our singing societies and to the presence of a goodly number of our people in the park. The Swedish minister to Washington, Mr. Lagercrantz, is also with us, and I take this opportunity to convey to you. Your Excellency, our appreciation of the interest you have shown by coming to New York to-day. Our consul and vice-consul are also with us. I saw a statement in a paper a few days ago to the effect that Swedes in New York have presented this beautiful bridge to the city. I only wish that such were the case ; but unfortunately we are only about fifty thousand strong in this neighborhood. Such a gift might well be possible out West, where, as you know, most of the Swedish immigrants settle, but not here. Indeed, there are parts of the West and Northwest, where for miles upon miles you will find Swedish settlements almost exclusively, and all in pros- perous condition. In Chicago the Swedes have even erected a statue to the memory of Linnseus, a duplicate of one erected in Stockholm just twenty years ago to-day. I remember the date well, because I took part in the celebration, being a student in Stockholm at the time. It is a great satisfaction to us Swedes, that Linnaeus, whose memory' is to-day honored all over the globe, was a man of peace. Every one has heard of our Gustavus Adolphus and Charles XII, not to mention the old vikings ; but our great scientific men — such as Linnseus, Berzelius, Scheele, Celsius, Edlund, Rudbeck and others — are kno'wn only to a select few. Even John Ericsson the great engineer, whose statue has been erected in Battery Park by the city of New York, is remembered and honored only on account of his ship of war, the "Monitor." The fact that he invented the fire-engine, the propeller, the solar engine, the hot-air engine and other wonderful machinery, is well-nigh forgotten, though we have in the city to-day about fifteen thousand pumping engines run with heated air on Ericsson's prin- ciples, and the solar engine is being used more and more in California. BICENTENARY OF LINN^US 47 His work was work of peace of the very highest character, and to be com- mended as such. There is one part of Linnseus's life-work which may not have been referred to to-day, and that is his work as an archeologist. While pursuing his studies in botany and zoology, Linnaeus naturally traveled a great deal around the country; in doing this, he made careful notes of the mounds, runestones and other marks left by the ancient inhabitants, which marks are very abundant all over Sweden. In fact, his writings on this subject have formed a basis for the very interesting archeology of Sweden. Personally, I have derived much more pleasure from this part of Linnseus's writings than I have from the others, although once upon a time I did know the Latin names of a few hundred plants. Once more I thank you, Mr. President, in behalf of the Swedes of New York, and I will close by proposing a cheer for the memory of Linnaeus, and will ask the singers to assist me with a gen- uine Swedish hurrah. At the close of the exercises at the Bridge, many people, in spite of the lateness of the hour, walked through the New York Zoological Park to note American animals known to Linnaeus. The party was under the guidance of Director Hornaday and Messrs. Ditmars, Beebe and Blair. In the evening the literary exercises of the day were continued at the Museum of the Brooklyn Institute of Arts and Sciences, Eastern Parkway, Brooklyn. After brief opening remarks by Mr. F. A. Lucas, Director of the Museum, the following address was read. A SKETCH OF THE LIFE OF CARL VON LINNfi. By Edward L. Morris. There is something of human interest in the personal side of any one's life, if we but know an avenue of approach. Such avenues are closed to most of us for most lives. The public careers of great men are matters of recorded or current history'. The professional activities and writing of men of science are open to those interested along similar lines; but often there is little opportunity to know the personal and characteristic things which are the real foundation and basis of success among men. Our presiding officer has elsewhere said, "In some ways the career of Linnaeus reminds one of a good old-fashioned fairy story in which the hero continually is being provided for. Time after time, Linnaeus was taken up 48 ANNALS NEW YORK ACADEMY OF SCIENCES by some man of wealth who practically supported him and gave him oppor- tunities for study and research. "Either genius was rarer in those days than now, or else it received more substantial recognition." In 1706, Nils Linnaeus, a Swedish pastor, and his bride Christina, began their home life in his parish in RSshult in SmSland in southern Sweden. About their cottage he had planted a garden of flowers according to a taste developed while living with an uncle. In this garden the young bride took special delight, only to grieve sorely at the effects of the heavy winter frosts, but reacting to the hope and anticipation of the awakening of spring. Here were more than four hundred species of exotic plants. For such a latitude and for such a period of the world's history, this was a most unusual col- lection. In the midst of the spring advent of the flovvers, in iSIay, 1707, there was bom a son in the home of the parish leader. He was baptized "Carl." To-day we celebrate, in honor and praise, the birth of Carl Linnoeus. The follovv'ing year, the family moved to Stenbrohult, to which were also removed most of the plants from the garden at Rashult. As soon as the boy Carl could walk, he daily visited the new garden with his father, where he was the more attracted to the flowers because in his babyhood the parents had often attracted his attention by many bright blossoms. A little later be had a bed for his own flowers, which he chose from the main garden. Later still, he was given a plot for his own garden beside his father's. At four years of age, after a visit to a country fair, he so persisted in asking questions that he practically knew all his father could tell him, — the Swedish names and the uses of the native plants. Typically, his mother delighted in the boy's absorption in the flowers (she was fond of them too), besides, this often kept the boy occupied for hours, — an important item in the daily program of the young housekeeping mother. Boylike, oftener than not Carl forgot the answers to his questions. His father noticed this and called the habit mischievous, and refused to answer further questions till the boy promised to remember what was told him. This parental training became of the highest value to the future Linnaeus. Many of the relatives of Nils Linnteus were ordained to the service of the church. It was in the wife's heart to have their son be the same. But he was averse to all reading not related to natural history or more particu- larly to botany. His chief activity was to wander over the fields and through the woods, bring home every new species he found, plant some, and dry and preserve others. With these he brought in several weeds, which caused no end of trouble to his father, as they spread to the beds of BICENTENARY OF LINN^US 49 exotic plants. He became so proficient in his knowledge of the local plants that the neighbors all called him "the little Botanicus." The story goes, that one day his mother found that he had even appro- priated her much-treasured Bible in which to press some new-found flowers, and she began gently rating him for this. "Dear child," she said, "you must not put herbs and flowers in my beautiful book. It would be quite a sin to spoil the Holy Bible." "Pray forgive me, mother! But these are the most beautiful flowers I have ever seen, so I thought I would preserve them best of all, for I have heard both you and father say that the Bible is the Book of Life; and surely, if I put the flowers between its leaves, they will retain their color, the Bible keeping them alive forever." "Child, v/hen we call the Bible the Book of Life, we mean by that, not the life we see before us, but the spiritual growth of our souls, for ever}- thought we think is a flower culled in the garden of our soul. There, as on earth, grow many various plants, some of Avondrous beauty, and others stained with sin. But every time we humbly read in the Sacred Writ, a seed is sown in our heart, which some day will bloom, and bear holy fruit." "How beautifully you talk, mother! " "Well, you must diligently read your Bible, and in your heart will grow the seed of goodness and humility; but I fear" — "What do you fear, mother?" "I fear you love the fair flowers of the earth too much to care for the seeds that were watered with tears in the Garden of Gethsemane." "O mother! no, I won't forget my Bible. But when I see a flower I think this way, ' Why does God make the cold, damp earth grow such lovely creatures with such beautiful colors ? Why, if not to make us happy with the sight?' And then I almost fancy the flowers saying with their petal lips, 'Look at us, and think how kind and good is God.' O mother! every flower must have been a thought by God." "Why, how you speak, child! W^ell, yes, you are right: it must be so." When Carl was ten years old, after an unfortunate experience with a private tutor, he was sent to Wexio, the capital of the diocese, to the grammar and higher grades. But here he failed because there was no teacher to lead and inspire him, but only those to drive. The boy mentally refused to be driven. Shortly he v/as put again under a tutor somewhat better than the former one; but in every subject except Nature he was considered a dunce. In eight years his father, with sorrow in his heart, became convinced that Carl never would make a preacher. His mother, realizing this also, rued the love she had felt for the flowers and the interest on his part which she sadly had fostered, and with pique declared to her second son, Samuel, that he never should devote himself to so useless and wasteful a study as flowers. 50 ANNALS NEW YORK ACADEMY OF SCIENCES In the words of another, "In this great distress, Pastor Linnaeus called upon a friend Dr. Rothman, a physician of Wexio who also taught physiol- ogy and botany in the school. His verdict, however, was, 'Well, a preacher Carl certainly never will be, but he might become a famous physician; and that profession will feed a man as well as the church. Your son is far advanced in natural history, and, vathout gainsaying, the foremost scholar in botany. If you v\'ill permit, I will take him into my house : he shall eat at my table gratis, and I will myself read with him during the year that remains before he can proceed to a university.' It need not be told how gladly father and son accepted this generous and well-timed offer." Carl now removed to Dr. Rothman; and this learned gentleman with great discernment made it clear to his pi-otege of what great advantage, and how indispensable, v.ere Latin and Greek for the study of medicine, botany and natural history. The dead languages now became endowed with a living new interest, and instead of Justinius and Cicero, he studied with enthusiasm Pliny's " Natural History," performing thus a double study at the same time. Dr. Rothman grew daily more and more attached to his pupil, who made amazing progress, and whose transcendent genius became more and more evident. He found great delight in guiding the young naturalist in his studies, but soon found, with little surprise and no envy, that his pupil far outstripped himself, for Linnseus could acquire no more from him. Linnseus must enter the university, and nothing remained but to get the certificate from the Wexio school. It was framed in very quaint and signifi- cant words; and it is curious that the trope of a tree, carried all through, should have been applied to the future of the professor of botany. It read as follows: "The youths in schools may be likened unto young saplings in a plantation, where it sometimes happens, although seldom, that young trees, despite the great care bestowed on them, will not improve by being en- grafted, but continue like wild untrained stems, and when they are finally removed ar.d transplanted, they change their wild nature, and become beautiful trees that bear excellent fruit. In which this respect, and no other, this youth is now promoted to the University, where, perhaps, he may come to a clime that will favor his further development." With this recommen- dation Carl Linnseus went to Lund, the southern university of Sweden, in 1727. Here Linnseus boarded and lodged at the house of one Strobaeus, who lectured in the university on natural history', geology, and botany. He was a man of acknowledged great learning in these sciences, and possessed a large private collection of stones, shell, biids and dried herbs. At this house also lived a German student of medicine, Koulas, eight years the senior of BICENTENARY OF LINNMUS 51 Linnaeus, who had the use of Strobaeus's library, and who took upon himself secretly to lend his young friend what books he required in botany. The old mother of the learned host had observed that a light burned in the small hours of the night in Linnseus's room, and, fearing fire, told her son, who quietly one night went up to Linnseus's room to surprise the negligent fellow, but was himself surprised to find the student in the dead of night busily comparing the varying opinions of the greatest botanists of his time. This surprise won the admiration of the teacher and his affection, and he at once gave Linn8gus the use of his library freely, and the keys to his collections, and, like Rothman, took the liveliest interest in the gigantic strides of progress. In 1728, Linnaeus changed to the University of Upsala to study under the renowned professors Roberg and Rudbeck. Here Linnaeus suffered much from poverty, often having barely enough food to sustain life. At length, under dire necessity, he was about to start for home to his father, when he made a last visit to the garden of the university. Just then there was a rare exotic plant in bloom. Linnaeus picked the flower, and was sharply reprimanded by a voice behind him. He explained that it was for a me- mento of the place, which he was now obliged to leave permanently. This aroused the interest and question of the dean, as it proved, — Celsius, senior. A result of this incident was, that Celsius saved Linnaeus to science then and there by taking him to his own house, giving him new and large opportunities at the university, tiding over the time of distress, and procuring for him opportunities as private tutor to some of the students below him. Here Linnaeus brought out his little thesis developing his sexual system of grouping plants. From now on, Linnaeus had a constant chain of promo- tions, spiced, disagreeably now and then, by jealousies wrought against him, but consisting of the delights of extensive, dangerous and economic travels, new positions of teaching and lecturing at home and abroad, and finally the full chair of botany at the University of Upsala. His greatest and ultimate joy was in the knowledge that his system of plant relationships became, before his death, the commonly accepted system of the civilized world. To his credit be it recorded again, that his system is the foundation of all modern concepts of the sexual evolution and differentiation, and consequent relationships, of all knowTi plants and animals, and especially of their nomen- clature. His personal and professional interest were so broad as to include special studies in insects and birds and in general zoology, as time allowed diver- gence from his life-work in botany. His writings covered the living things of the Old and New Worlds, and comprised some seventy or more titles. His personality was of the kind which inspired every pupil coming under 52 ANNALS NEW YORK ACADEMY OF SCIENCES him to branch out for himself in some line of natural history. His students became scattered throughout the world. Up to the last, and as much as his failing health would allow, Linnaeus kept up a lively and progressive interest in his science. Finally, tired of life, and forgetful of all honors which had been so keen a delight to him, he passed beyond peacefully on the 10th of January, 1778. His works and his name live forever. At the conclusion of Dr. Morris's address a musical selection was rendered by the Glee Club of the United Swedish Societies, after which the following address was delivered. LINN.EUS AND AMERICAN NATURAL HISTORY. By Frederic A. Lucas. I presume that the question first in the minds of many present is, Why have we met this evening? why should we celebrate the two hundredth birthday of Linnseus? In a general way, Linnseus may be said to have systematized the study of natural history, and arranged its known facts in an orderly manner; but his special claim to our gratitude is the invention or perfection of what is called the "binomial system" of nomenclature, that is, the use of the double name for each species of plant or animal. This may seem a small matter. In fact, those who ask Why doesn't every animal have a common name ? might think they had reason to feel an}i;hing but grateful ; but it was really one of the greatest advances made in natural history. For in science it is not enough to accumulate facts, they must be set in order, or classified, so as to be available. In fact, Huxley termed science "classified knovdedge." Before the day of Linnseus, animals were mainly known by their descriptions or their vernacular name. The lion, for instance, would be called the "great tan-colored cat with a mane;" and, in order to indicate what species were related, it would be necessary to specify them each and all. As the rising tide of commerce of the eighteenth century brought to Europe scores of animals previously unknown, the number of recognized species increased so rapidly that it promised to be a difficult matter to keep track of them. It was at this time that Linnseus devised the plan of apply- ing to each animal a general or generic name which should indicate the immediate group to which the animal belonged, and a special or specific BICENTENARY OF LINN^US 53 name to apply to that particular kind of animal alone. And so binomial nomenclature was born. It has been claimed that Linnjeus was not the first to use the binomial system, but, if not, he was certainly the first to employ it consistently and to frame rules relating to such use. Linn^us wrote in Latin not as a matter of affectation, but because Latin was the common language of culture and science, and to this day many naturalists still write descriptions of new species in Latin, or preface their accounts with a brief diagnosis in that language. Had he written in Swedish, his native tongue, his audience would have been a small one, probably limited to his native land; as it v/as, his works were understood by all the natu- ralists of the day. Hence his scientific names which w^ere Latin names are, like a gold coin, current the world over, while the so-called "popular name" is restricted in its use, and circulates only in the country where it is coined. But Linnseus did much more than devise a scheme of nomenclature : he systematically defined each and every group of plants and animals with which he dealt, giving their chief characters in a few brief words; and the small groups, or genera, he combined in large divisions termed "orders." It matters not that the genera of Linnseus have since been divided and sub- divided many times, the underlying principle of assigning certain definite characters to each animal remains the same. Linnaeus was a born classifier. He was not happy until he had duly set in order the facts and objects that came under his notice ; and while he did not, it is true, carry this to the extent of the eccentric Rafinesque, who made several genera and species of thunder and lightning, he did propose a system of classification for diseases wherein they were duly assigned to their respec- tive families and genera. To many the term "classification " is repellant. It seems to signify some- thing with which the ordinary man has nothing to do, when really it is some- thing with which every one is, or should be, concerned ; for classification is simply arranging things in their proper places, and putting things of a kind together. And the man who puts his cuffs in one place, his collars in another, and arranges his shoes in a row on the top shelf of a closet, is a classifier. The naturalist is confronted by the same problem as a general,— that of grouping or arranging the various plants or animals so that he may know where each one is to be found, or where to assign any new form that may come to light. For an army is not merely a large number of armed men, it is an orderly assemblage of men so classed and grouped that they can be handled by one man. And the classification of the animal kingdom, for example, is very similar to that of an army, and to the same end, — that any one may put into its proper place each of the thousands of units with which he has to do. 64 ANNALS NEW YORK ACADEMY OF SCIENCES And Linneeus marshaled plants and animals as a general marshals his troops. And just as an army is composed of thousands of individuals, dis- tinguished as officers and privates, formed into companies, regiments, brigades and divisions, so the thousands of species composing the animal kingdom are grouped into genera, families, orders, classes and phyla. In doing this, Linnaeus instituted many minor reforms; for example, his char- acters were given in a definite order, and following the diagnosis was the synonymy, or list of names under which the animal had been described, and works in which it had been published. He was the first to strip natural history of its verbiage, and express himself in clear and concise language, and, had he lived to-day, I doubt not he would have been an advocate of spelling reform. And yet, after all, this scheme of nomenclature is but a part of the ser- vice Linnaeus rendered to natural history. It is not merely that his genius grasped the fact that nature was order, and that he devised methods for expressing this order; his zeal in the pursuit of knowledge gave a stimulus and purpose to the study of natural history that it had never felt before. In a way, his influence may be said to have been much like that of Agassiz in the United States, "He imbued [his pupils] with his own intense acquisitive- ness, reared them in an atmosphere of enthusiasm, trained them to close and accurate observation, and then despatched them to various parts of the globe." It was not so much what he knew himself as the enthusiasm he inspired in others, that made him a power felt throughout the world. It must ever be borne in mind that nomenclature, or the naming of plants and animals, is not the end of natural history, but only a means to an end, — a fact that many of our younger naturalists are prone to overlook. Too many of them seem to think that the great aim of the naturalist is to write "new species" after as many names as possible, when, to my mind at least, the making of new species is the most trivial work of the naturalist. It is important work, but only a step on the pathway of knowledge. The real problems are. Why do these species exist? what forces have brought them into existence ? and what are their relations with one another ? The man who heard an overture for the first time, after listening a while turned to his friend with the query. When are they going to stop tuning up, and commence to play ? So you may wonder why I chose for the title of this address "Linnaeus and American Natural History." The truth is that Linnseus is so intimately connected with all natural history, that American natural history forms but a small part of the whole. And yet Linnaeus was intimately concerned with the development of American natural history by his acquaintance with those men of science who were gathering and making known the fauna and flora of this continent ; and as plants and animals were BICENTENARY OF LINN^US 55 brought to Europe, most of them found their way to Linnaeus, and many were definitely named by him for the first time. The twelfth edition of the famous "Systema Naturse" describes 210 mammals, 78 of which are Ameri- can (including under that term North and South America) ; 790 birds are noted, of which 260 are American; and 88 of the 124 reptiles are also American. We think of Audubon, Baird, Coues and Ridgway as the great American ornithologists, and they are great; but a glance at the check-list of the American Ornithologists' Union shows how prominent a part was played by Linnseus. The list of 1889 gives 729 species and subspecies. No less than 202 of these were named by Linnaeus ; while Audubon, the father of American ornithology, named but 33. Twenty-five bear the sign-manual of Coues, and 104 of Ridgway. We must, it is true, remember that a considerable number of the birds named by Linnseus are species common to Europe and North America, but, on the other hand, it must also be borne in mind that many named by Ridgway are what are called subspecies, which were not recognized in the day of Linnseus. In the time of Linnseus there were few naturalists in the United States, but those were active ; and that they approved of his methods is shown by a letter of Collin to Linnseus, in which he says, "Your system I can tell you obtains much in America. Mr. Clarion and Dr. Golden at Albany are complete professors, as is Dr. Mitchell at Urbana, Va." If this seems a pitifully small number to us, it must be remembered that in those days naturalists were few in number, and natural objects studied but little; and twelve years later there were in all England but seven botanists who vv^ere fol- lowers of the Linnsean methods. Those were the good times when one man knew the plants and animals of the whole globe. Now a naturalist may devote his entire time to the study of one small group, and the names of other plants and animals are often as unfamiliar to him as they are to the average man. It is interesting, almost amusing, to see how little an idea Linnseus and his contemporaries had of the number of the animals in the world, for their most liberal estimates were very far from the facts. And this lack of knowl- edge Linnseus realized when he wrote at the eud of his "Systema Naturse," "Ea qua scimus sunt pars minima eorum quae ignoramus." Thus Ray in 1693, a short time before Linnseus began his career, estimated that there were about twenty thousand animals, including insects, in the whole world; and this was a very liberal estimate, for he actually described less than four thousand. Now, Ray was what would be termed to-day a "lumper," and divided all living things into four great orders, — insects, fishes, birds and beasts. 56 ANNALS NEW YORK ACADEMY OF SCIENCES the last including reptiles. The number of beasts he stated to be a hundred and fifty, adding his belief that "not many that are of any considerable big- ness in the known regions of the world have escaped the cognizance of the curious." The birds he considered might reach as many as five hundred. Contrast this with the more than twelve thousand species so far described. The number of insects he considered might possibly reach twenty thousand species, a long way from Sharp and Walsingham's estimate of two millions, or Riley's of ten millions. Nowadays this estimate of Ray provokes a smile, and yet we can find an example of much greater complacency shown by one of our noted scientific men of much more recent date ; for Dr. Coues about ISSO thought that few mammals remained to be discovered in North America. How badly he was mistaken is shown by Dr. Allen's review in 1894, showing that the number of recognized species had more than doubled in ten years, rising from 181 in 1880 to 369 in 1890; and since then many more have been described, not merely small creatures that to the ordinarv- observers are alike, but large animals like bears and mountain-sheep. It well illustrates the activity displayed by naturalists of that day to say that by 1758 the number of known mammals and reptiles had increased to 334 and of birds to 790; the figures in the one case being an advance of a hundi-ed per cent over those of Ray, and in the other of fifty per cent. How thoroughly the world is being ransacked for new animals, and how actively naturalists are engaged in their description, may be gathered from the following figures. Up to 1830, species to the number of 71,598 had been described, by 1881 the number had risen to 211,553, and by 1896 to 366,000; more than 150,000 species having been described in fifteen years. And the vast and ever-growing host of living things — the beasts of the field, the birds of the air, the fishes that are in the water about the earth, to say nothing of the myriad species of the plant world — are each and all named in accordance with the method devised by Linnaeus two centuries ago. Linnaeus builded better than he knew, and his work has stood the test of time; and the methods he devised for classifying and naming animals are those in use now. His details may have been faulty, and the groups he considered as genera may have been divided and sub- divided, but his plan stands. Scores of animals known to Linnaeus have been swept out of existence, and thousands that he never knew have been discovered; but the stimulus given by him to the study of nature remains unchecked, and to-day in many countries the members of learned societies have assembled, as we have gathered here, to do honor to the great Swedish naturalist. Sweden, indeed, chanced to be the birthplace of this great man, but genius is not fettered by time and space, belonging rather to all time and to the whole world. BICENTENARY OF LINNJEUS 57 At the conclusion of Mr. Lucas's address the Glee Club sang a second selection, and then the evening exercises ended with an exhibition, by means of stereopticon views, of plants and animals known to Linnaeus, in charge of Dr. A. J. Grout and Mr. Lucas. In the Borough of Manhattan the day was rounded out at the New York Aquarium, Battery Park, where the New York Zoological Society gave a reception to the Academy and the guests of the occasion. This function likewise commemorated the centennial anniversary of the erection of the building and gave the first view of the collections by night. A fea- ture of the reception was the exhibition of forms of marine life known to Linnseus. 5j» ?J^ *^ 3|* Jp ^j* 5|i An important and highly interesting feature of the Linnaeus celebration lay in the following documents contributed by sister societies in many parts of the world, and letters written by several of the Honorary Members of the New York Academy. Each is reproduced here in the language in which it was sent in. Kungl. Svenska Vetenskapsakademien, Stockholm. It is with great pleasure that the Royal Swedish Academy of Sciences has received in these days, from all parts of the world, the most gratifying testi- monies of the great admiration and esteem in which our first president, Carl von Linne, is held by all those who love and study nature. Your invi- tation has also been accepted with great gratitude : it was, however, received so late that it was impossible to take any measures for participating in your celebration in such a way as would have been desirable to us. You have expressed your wishes that we should contribute an official document appre- ciative of the work of Linne. There is, however, no opportunity now to prepare such a document, and we must thus confine ourselves to a short statement elucidating our opinion. There were many great naturalists before Linne, if we count from Aris- toteles to Ray and Willughby. There was certainly a great amount of knowledge, also, concerning animals and plants; but there was no system, no scientific names or terms. The facts that were known in natural history before Linn^ were thus heaped without order, or with very little order, like a pile of bricks and stones at a building-place. Linn6 was the great architect who made the plan for the erecting of the building, — the system; and he furnished at the same time the mortar — the nomenclature — for cementing 58 ANNALS NEW YORK ACADEMY OF SCIENCES together the stones and bricks. It may be admitted that more practical and more beautiful buildings have been constructed since that time in the scien- tific world; but he was and he remains the great master, who, with bril- liant genius and admirable skill, first taught us how to put in order and systematically arrange the material, and thus make a true science of natu- ral history. This has also been universally admitted; and the renowned British naturalist Pennant ^^Tites about this part of Linne's work, "He hath in all his classes given philosophy a new language; hath invented apt names, and taught the world a brevity, yet a fullness, of description unknown to past ages." Many persons not familiar with Linne's work have believed that Linn6 contented himself with describing the exterior of the objects in nature, and then named them. Nothing can be more erroneous; that is proved by the program or the "Methodus" which Linne published even in the first edition of "Svstema Naturje." This "Methodus" is in its thirtv-eight short paragraphs the fullest and richest program which any student of natural history has ever published. Referring to this we may affirm that no branch whatever of biological study was neglected or underrated by Linn^. He grasped fully the importance of the study of anatomy, and he advised his scholars to dissect animals and also to make a frequent use of the magnify- ing glass. His ardent love of living nature made him an excellent biologist in the restricted sense of that word. Even if his greatest works were of a systematic and descriptive nature, it becomes e\ndent to any one who has only a superficial knowledge of what Linne has written, that his genius extended with unbounded flight to cover much wider areas of philosophical speculation. Although he did not see it in the light of the theory of evolution, — it was indeed far too early for that, — the general struggle for existence, as well as the idea of sexual selection, was well known to him. And many other problems of modern times did he touch. Let us only recall the fact that to the pious and pure mind of this great naturalist there was no objection to place homo sapiens as the first Hnk in the continuous chain of organisms. His works may shine with everlasting brightness through all ages, as long as mankind devotes itself to the study of nature. His name is cere perentiius, but this Academy of Sciences and the whole people of Sweden feel deeply and are gratefully touched by the honor which now is bestowed upon our great compatriot, when his name is given to a monumental bridge connecting the Botanical Garden and the Zoological Park in New York.

The Royal Society of Sciences at Upsala has had the honor and the pleasure of receiving your letter, informing them of the impressive manner in which the memory of their great countryman, Carl von Linne, will be celebrated in the metropolis of the United States. To every Swede, and especially to our Society, whose honor it is to count Linn6 as the greatest ornament of its ranks, it is highly gratifying to see that the memory of the man whom all the world recognizes as princeps hotani- corum, is also beyond the Atlantic held so sacred that the two hundredth anniversary of his birth will be celebrated there with the same love and reverence as in his own countr}\ And we fully appreciate the delicate courtesy which has led you to immortalize his name among you by dedicat- ing to him the beautiful bridge which unites your Botanical Garden with the Zoological Park. The necessity of answering your honored letter without delay renders it impossible for the Royal Society of Sciences to enter more fully on the epoch- making significance of the great Linn^'s life and work. Nor do we consider it necessary for us to do so, least of all in relation to your renowned Academy, which takes the lead in the grand scientific evolution of America. Do we not both realize that Linne's great genius has laid the foundations on which botanical science goes on building this very day? We both realize the unceasing debt of gratitude which both hemispheres owe to his immortal name. And so on both sides of the Atlantic we celebrate with deep-felt enthusiasm the two hundredth anniversary' of his birth. We offer you our best wishes on the memorable day, and congratulate you on your successful work in the immense field of learning. J. A. Ekmax, Archbishop of Sweden, President. N. C.

In mv working-room at the Geological Survey of Nonvav for many years I have had only one portrait hanging, — that of Linnaeus. 1 regard him as the household spirit of every good naturalist. 60 ANNALS NEW YORK ACADEMY OF SCIENCES The Geological Commission of Finland. On behalf of the Geological Commission of Finland, we desire first of all to express our high appreciation of the honor rendered us in inviting the Commission to take part in the celebration, by the New York Academy, of the two hundredth anniversary of Carl von Linne. We are proud to think that we have some right to reckon this great memory among our own, because Finland in Linne's time was united to Sweden; and a large number of us Finlanders are still, by language and descent, connected with that land. Among his disciples were also several of our countrymen ; and the interest which ever since that period has existed here for the study of botany, and also of zoology, we regard as a direct inheritance from Linne's time. Not only naturalists ex professo have taken part in the investigation of the flora and fauna of our country, but also physicians, clergymen, government officials and the general public, who have, ever since Linne's days, constantly and with zealous eagerness lent their aid to the augmentation of our store of knowledge in things pertaining to natural science. By his travels, among the first which were undertaken for a purely scientific purpose, Linne has also given an example to the numerous explorers who since his time have gone out from northern lands — among those born in Finland we may mention Laxman the explorer of Siberia, Castren the linguist, and Baron A. E. Nordenskiold, the geologist, and discoverer of the Northeast passage — and to all those who, after Linn6's time, have united the courage and energy of the pioneer with scientific thoroughness. We geologists remember in especial that Linne — who had very correct ideas of the geological sequence among the silurian rocks of Sweden and the importance of fossils, and whose conception of the geological importance of the deluge was for his time unusually free from bias — can be reckoned among the early pioneers of geology and as a predecessor of the great natu- ralists who somewhat later, in Scotland and Saxony, laid the foundation- stones of scientific geology. He had a notion of the immense length of geological time, and expressed opinions which contained the germ of the actualistic doctrine that afterwards proved so fruitful for our science. It has been the mission of the Anglo-Saxon nations to work out this doctrine and to build up on this basis the science of geology. When in our days we Northerners see without jealousy the hegemony in natural science pass over to the great nations which have continents for their field of re- search, we still remember with pride that it was at one time held by the little nation to which Linne belonged, and see in the festival with which BICENTENARY OF LINNMUS 61 your honored society celebrates the two hundredth anniversary of his birth a recognition that all scientific exploration which is carried on in an unpreju- diced spirit of order and truth is a work in the vSpirit of Linne. Remembering the bond which thus connects your great nation with the small countries of northern Europe, we wish especially to recall to you one of Linne's disciples, the explorer Pelir Kalm, professor of botany at the University of Abo in Finland. He was very highly esteemed by his great teacher. In Linne's list of the naturalists of his time, in which each one was distinguished with a certain rank, Linn^ himself was general, and Kalm had the rank of major. Commissioned by the Royal Swedish Academy of Sciences, Kalm, as is well known, traveled far into North America, and afterwards published an uncommonly accurate and minute account of his observations, which was translated into several languages. He penetrated into what was then considered the Far West, to the Lake of Ontario ; and it was through his letters to Benjamin Franklin, in which Kalm with his usual minuteness described the Falls of Niagara, that this great wonder of nature first became more generally known. What a lapse of time has passed since that visit of the disciple of Linne to North x\merica! — a time measured more properly by the wonderful development of civilization than by the number of years that have gone by. Over this vast continent, where then were forests and prairies, the abodes of the wild Indian, has the white man now built his homes, and it is strewn with schools in which the children learn to designate the plants and animals with the names given them by Linne. Everywhere there are universities in which the study of natural science is carried on with the aid of means and appliances which Linne never could have dreamed of. Where Kalm, at the mouth of the Hudson River, found a town v>'hich he says was then "about half as big again as Gothenburg in Sweden," lies now one of the greatest cities of the world; and in this city the two hundredth anniversary of Linne is now celebrated in a way that shows that his memory is as much honored there as in his fatherland. What a proof of his greatness, v/hat a guaranty that he will forever be regarded as one of the master-minds of mankind! J. J. Sederholm. Benj. Frosterus. Senaat der Rijks-Universiteit te Leiden. The Leiden University Senate has the honor to present its congratula- tions to the New York Academy of Sciences on the occasion of the commem- 62 ANNALS NEW YORK ACADEMY OF SCIENCES oration festivities celebrating the two hundredth anniversary of the birth of Carl von Linne. The whole scientific vi^orld unites in grateful veneration of an admirable scholar, whose reputation is least of all lost in the land where he spent three of the most fruitful years of his life. Our Senate ex- presses its feelings of cordial sympathy with the way in which the New York Academy of Sciences intends to celebrate the anniversary of his birth by the erection of an architectural monument symbolizing the work of a man whose genius embraced the two realms of living nature. For the Senate W. NoLEN, Rector Magniflcus. H. P. WiJSMAN, Secretary. Professor A. A. W. Hubrecbt, University of Utrecht. {Honorary Member of the Academy.) The great Swede whose birth — now two hundred years ago — will be commemorated all over the world on Ma}' 23, passed many years of his life in Holland. It is thus natural that inany local reminiscences are connected with his name in different parts of this country. If we allow our thoughts to go back for more than a century and a half, we can imagine Linnaeus roaming about on his botanical excursions over those same fields between 's Graveland and Hilversum where Hugo de Vrics lately encountered an emigrant from the United States (Oenothera lamarckiana) that was to be- come a starting-point for new and important speculations about the species problem. The foundations for an answer to that problem were laid in a quite mas- terly manner by Linnaeus. In the latter half of the nineteenth century we have, however, been accustomed, after reading Darwin's works, to consider the problem as non-existing; species, apparently, being in slow and imper- ceptible continuity. Hugo de Vries has again limited species between the occurrence of two mutations, each species thus being a real entity in time and in space. This does not prevent de Vries from being at the same time one of the stanchest disciples of Darwin, in whose steps he is treading. Linnseus's species differ from de Vries's in that they are the primary network between the meshes of which de Vries has spun out the lacework of the mutation theory. The new generations thus attempt to continue Linnreus's and Darwin's work, and unite in paying homage to the memory of the foimder of the " Systema Naturae." BICENTENARY OF LINN.EUS 63 L'Academie de M€decine de Paris. L' Academic de Medecine de Paris est heureuse de repondre a rinvitation qu'elle a re9ue de I'Academie des Sciences de New- York, a I'occasion du deuxieme centenaire de la naissance de Liniie. EUe s'associe cordialement aux hommages rendus a la memoire de I'illustre naturaliste par les corps savants de la grande cite americaine. Tout a 6te dit sur Toeuvre de Linne et sur la revolution qu'il a op^r^e dans les sciences naturelles. Au milieu de la confusion et de I'obscurite qui regnaient avant lui, il a su, le premier, degager et rendre fecondes les idees generales eparses dans les ecrits de ses devanciers; partout il a porte I'ordre, la clarte et des reformes heureuses. Obsers'ateur incomparable, a I'amour de la verite, il joignait une imagi- nation vive, un esprit fertile et sagace, I'expression verbale pittoresque et le sentiment profond des choses de la nature. Ses ecrits occupent depuis longtemps la premiere place dans I'estime des savants, et Ton se demande, en voyant leur prodigieuse etendue, ce qui doit le plus etonner, du nombre de ces ouvrages ou de I'importance de chacun d'eux. Mais, de tous les titres de Linne a la reconnaissance de la posterite, le plus beau est sans contredit celui de fondateur de cette langue scientifique nouvelle, la nomenclature binaire, qui constitue le plus grand progres accompli dans les sciences naturelles au dix-huitilme siecle. A la prolixite confuse des descriptions ant^rieures, il substituait un langage net et precis, en introduisant I'usage de designer les ^tres par un nom de genre, qui les unit, et par un nom d'esp^ce, qui les distingue. La nomenclature linneenne s'est etendue a toutes les branches de I'histoire naturelle ; elle en a prodir gieusement facilite I'etude en fournissant une langue commune aux savants de tous les pays. Le systeme de classification etabli par Linne n'a pas moins contribue aux progres de la botanique pendant pres d'un siecle. Dans ce cadre artificiel, les plantes nouvelles se rangeaient aisement d'apres un petit nombre de caracteres empruntes a la fleur et judicieusement choisis. Des lors I'etude des vegetans: de\'int accessible a la multitude, les recherchcs scienti- fiques se multiplierent dans toutes les parties du globe avec une activite considerable. Toutefois, I'esprit philosophique du grand naturaliste ne pouvait manquer de saisir toute I'importance d'une methode plus parfaite, et, s'il nc lui a pas et^ donne de la realiser lui-meroe, on pcut dire du moins qu'il en a etc le plus ardent promoteur et que nul, plus que lui, n'a contribue a I'avenement de la grande reforme operee plus tard par T^aurcnt de Jussieu. 64 ANNALS NEW YORK ACADEMY OF SCIENCES Professeur de medecine, Linne s'est efforc6 de diriger I'etude de la botanique vers les applications a I'art de gu^rir. II a cu Ic merite de formuler nettement le principe qui devait servir de guide a la recherche des propriety medicamenteuses des plantes, principe fond6 sur les analogies des caracteres botaniques et des caracteres chimiques des vegetaux. Si les successeurs de Linne ont parfois exagere la port6e de la theorie, elle n'en a pas moins ouvert une voie feconde aux recherches ulterieures. L'ancienne Societe Royale de Medecine de Paris, dont notre Compagnie a recueilli I'heritage, a compte jadis I'illustre professeur d'Upsal au nombre de ses Associes etrangers. L' Academic de Medecine de Paris est done particulierement qualifiee pour celebrer avec vous I'anniversaire du grand naturaliste su^dois. Elle remercie 1' Academic des Sciences de New- York de I'avoir convi6e a cette commemoration, qui lui permet d'exprimer ses sentiments d'admiration et de reconnaissance pour le savant dont I'oeuvre geniale a projete sur le monde une si vive ct si puissante lumiere que I'eclat n'en est pas encore affaibli. Ariiand Gautier, Le President. Jaccoud, Le Secretaire 'per'petxiel. Universite de Lyon. Le Conseil de I'Universite de Lyon est heureux de s 'associer moralement au deuxi^me centenaire de la naissance de I'illustre naturaliste Suedois Charles Linne. II addresse a cette occasion I'hommage de son admiration profonde pour le createur de la premiere classification scientifique des rfegnes animal et vegetal; pour I'inventeur de la nomenclature binominale qui a introduit une si lumineuse clarte dans le chaos jusque la obscur de la nomen- clature biologique; pour I'immortel auteur du " Systema Naturre" qui est le premier inventaire universel des richesses du monde anime. II envoie en meme temps h. 1' Academic des Sciences de New- York 1 'expression de sa gratitude la plus cordiale pour I'aimable pensee qu'elle a cue d 'associer I'Universite de Lyon a cette fete de la Science internationale. T. JouBiN, Le Recteur, President duCo7iseil de I'lIniversitS. Societe des Amis des Sciences Naturelles de Rouen. La Society des Amis des Sciences naturelles de Rouen (France) a I'hon- neur d'exprimer a I'illustre Academic des Sciences de New York sa vive BICENTENARY OF LINNAEUS 65 satisfaction de savoir qu'un pont de cette admirable ville sera d^di^ a I'immortel Linn6, dont les travaux geniaux constituent la base de la taxi- nomie, et dont le nom sera perpetue a jamais par les innombrables especes animales et vegetales qu'il a d6crites. La Soci^te des Amis des Sciences naturelles de Rouen prie I'illustre Academic des Sciences de New York d'agreer I'hommage de sa respectueuse admiration, joint a 1 'assurance de ses meilleurs sentiments de confraternity. Henri Gadeau de Kerville, President. Society d'Histoire Naturelle de Toulouse. eloge de linn^, appreciative de son (EUVRE. "Tibi suaveo dsedala tellus Suramittit flores." — Lucrece, De Nature Rerum. C'est a vous, divin naturaliste, que runivers entier pr^sente en ce jour ses plus belles fleurs. Nous saluerons tout d'abord le savant qui d'un trait de son puissant g^nie, saisit la structure intime des vegetal. Lui aussi a eu la gloire d'ouvrir un des sanctuaires de la nature et de s'initier le premier a quelques-uns de ses secrets. "Effringere ut arcta Natura; primus poetarum claustra cupiret." — Lucrece. Avant Linne le v^g^tal d'^tait qu'un vulgaire objet d' admiration, I'elemcnt a la fois r^jouissant et decoratif du paysage. Mais le g6nie du botaniste que nous fetons cut y lire tout un monde nouveau, et de la comparaison de ce monde avec celui des animaux sut brillamment deo-ager la nation de hie- rarchie entre les deux regnes, entre le v^g^tal et I'animal. Alors se dessina en quelque sorte le premier anneau, la trame primordiale qui devait bientdt amener I'esprit de I'homme a se rcprescnter une chaine complete des ^tres. Reconnaissons done en Linn6 un ancetre de Darwin. Mais le regne vegetal s'est en quelque sorte anim6 sous le regard de ce scrutateur amoureux de la nature. Qu'est ce en effet pour Linn^ que cette riante parure que nous nous plaisons a appeler corolle de la fleur? Tout simplement le lit nuptial des organes sexuels, ceux qui reproduiront I'csp^ce. Et que seront, examines attentivement, chacun de ces derniers organes, tant mS,le que femelle, sinon un renduirent, une ebauche un "caneoas" de celui de I'animal, comme a fait si bien ressortir le physiologiste Bichat? C'est cette d^couverte qui constitue le trait original et saillant entre tous, le trait de g^nie, r^p6tons le, de I'ceuvre de Linn^. Derri^re I'homme de g^nie nous devons admirer le philosophe. 66 ANNALS NEW YORK ACADEMY OF SCIENCES Aussitot que Linne eut eue bieii presente dans son esprit la continuite de la clialne, disons mieux de I'echelle des etres vivants avec leur lois generales communes aux deux regnes a la fois, il eut aussi toutes desporees d'une fa9on tres reguliere les bases d'une classification des vegetaux. -^11 les r^partit en vingt quatre categories, basees toutes sur les rapports des organes males et des organes femelles dans une meme fleur ou dans des fleurs separ^es, les organes sont respectivement appelfe les "maris et les femmes" par Linne. Signalons a titre de curiosite: La elasse xiv, Didynamie. — Deux puissances quatre maris dont deux plus grands et deux plus petits. La elasse xxi, Monoecie. — Une seule maisoii : les maris habitent avec les femmes dans des lits differents (dans la meme maison). La elasse xxii, Diaicie. — Les maris habitent des domiciles et des lits divers. La elasse xxiii, Polygamie. — Plusieurs noces : les maris habitent dans des lits distincts avec des epouses legitimes et des concubines. La elasse xxiv, Cryptogamie. — Noces cachees, les noces sont celebrees clandestinement. Cette theorie, toute geniale qu'elle etait, n'etait pas cependant destinee a subsister. EUe n'en demeurere pas moins comme le plus beau monument de Tdge d'or de la botanique. Aussi le chemin etait fray^ dans le domaine vegetal: la notion de la classification allait devenir un chapitre important des etudes philosophiques, et, gr^ce a une plus complete connaissance de la nature, la philosophic elle meme allait prendre un nouvel essor, agrandir, transforme son domaine, descendre des hauteurs metaphysiques a des donn6es plus positives. Et cela jusques au jour ou le progr&s incessant des sciences naturelles viendrait introduire une nouvelle idee geniale, grace a laquelle les deux regnes auraient des tendances a la confondu en un seul : par voie de progres nous avons nomme cette evolution dont Linne avait jet6 les premiers fondaments. Comme il etait loin, quand il ecrivait la Philosophia Botanica de pouvoir entrevoir seulement la grandeur future de I'edifice dont il jetait las assises ! Quelle est enfin I'epithete qui convient a Linne au milieu de ce que Ton pourrait appeler le "choeur des botanistes?" Un savant Suisse, Rueper, s'est pW a caracteriser chacun des grands historiens du r^gne vegetal. II nous represente le tr6s subtil Adanson. I-« tres ingenieux Bernard de Jussieu, les eminents Robert Brown et De Candolle, quant a Linne, il a sa place sureminente, c'est le divin Linne, divers Linnaeus! Le divin Linn6! nous lui maintiendrons ce sublime titre, puisque ce fut un des privil^es surhumains pour ainsi dire, dou6 des lumieres tout a fait superieurs, qui sert ouvrir une des portes d'un sanc- tuaire de la nature, introduisent aussi a sa suite dans ce domaine repute BICENTENARY OF LINN AW S G7 inaccessible jusques a lui toute une legion d'eminents travailleurs destines a eu explorer les recours et a continuer son oeuvre! Le divin Linne ! n'avait-il pas en effet comme profondement gravee dans tout son Hre I'empreinte de cette Divinite qu'il ne perdit jamais de vue ? ne considerait il pas I'oeuvre qu'il avait accompli dans la science comme le plus be) hommage qu'il fut capable de lui rendre quelques unes de ses pages redisent plusieurs fois le nom du Createur de tous les etres. Comme nous regrettons de n'avoir pu retrouver cette pri&re, si sublime dans sa brevity, dans laquelle il exprime a I'auteur de la nature sa reconnaissance eternelle pour la joie qu'il resscnt de I'oeuvre qu'il lui a permis d'accompli! Bornons nous a mentionner les invocations qui terminent un de ses chapitres: — "O Jehovah, quam ampla sunt opera tua! Quam ea omnia in sapientia fecisti! Quam plena est terra possessione tua!" Ce sont les propres accents de David, au psaume 103, mais sur un ton plus renforce. Saluons en terminant I'heureuse patrie de Linne, la Suede. La race des genies, si brillamment inauguree par le botaniste dont nous fetons aujourd'hui I'annivei'saire deux fois seculaire de la naissance, cette race disons nous, ne parait pas volontaire s'epuiseren Scandinavie. Qu'il nous suffire de nommer un contemporain, le celebre chimiste Arrhenius, qui semble lui aussi, par sa belle theorie des ions, avoir revolutionne a la fois le monde chimique et le monde electrique, preparant ainsi une nouvelle voie aux decouvertes indus- trielles de I'avenix'. L'oeu\Te de Linne etait dans le regne vegetal. Arrhe- nius a roula la tente dans un troisieme r^gne, celui dont toute vie est exclue; les secrets qu'il croit en oil arraches a la nature sont d'un ordre encore plus intime et plus mysterieux que ceux que lui avaient derobes le grand botaniste. Comme consequence des travaux de ces deux grands hommes, la science pent dire aujourd'hui avec plus de raison que le hero de Lucrece : II y a plus bien de mysterieuse dans la nature: nous avons triomphe de toutes les barrieres, et nous avons conquis la notion du degre de puissance qu'a 6te delimite a chaque etre et de la borne qu'il ne pent depasser. "Unde refert nobis victor quid ponit oreri, Quid nequeat, finita potestas denique eusque Quanara ut ratione atque alte terminus hoerens." Lucrece, De Natura Rerum. H. DE Lastee, Bibliothecaire. 68 ANNALS NEW YORK ACADEMY OF SCIENCES Professor Charles Barrois, University of Lille. (Honorary Member of the Academy.) C'est un tr^s doux sentiment pour les savants de la vieille Europe de vivre un jour en pleine communion d'idees avec les savants de la jeune Am6rique, pour jeter le souvenir d'un maitre commun, d'un bienfaiteur de la science. L'histoire, les nations, I'homme ont bien 6volu6 depuis le jour de Linn^; le respect d(i a son nom demeure, et s'en va grandissant. Puisse son exemple faire des emules nombreux dans votre grand pays, qui de nos jours rend de si eminents services a la cause de la science. Eaiserliche Leopoldinisch-Garolinische Deutsche Akademie der Naturforscher, Halle A.S. Der New York Academy of Sciences entbietet die Kaiserliche Leopol- dinisch-Garolinische Deutsche Akademie der Naturforscher zu der Feier des 200-Geburtstages von Karl von Linn]£ einen Gruss, da sie sich einea weiss mit derselben in dem Bestreben den grossen schwedischen Natur- forscher zu ehren. War doch unsere Akademie die erste wissenschaftliche Korperschaft, welche bereits 1736 den jungen Linnaeus in ihre Mitte aufnahm und ihm den glanzvollen Beinamen eines Dioskorides Se- cundus beilegte. Wohl auf kcine anderen Geistesheroeu kann das stolze Wort: Deus creavit, Linnaeus disposuit auch nur annahernd angewendet werden. So unscheinbar die Linnaeus borcalis ist, umso grosser steht Linn6 als Naturforscher da. Aber nicht nur als Botaniker und Zoologe erwarb der Jubilar unsterblichen Ruhm, auch in der Medizin leistete er fiir die damalige Zeit in der Materia Medica wie der Diatetik Hervorragendes und war wohl derjenige, welcher in Schweden fiir die pathologische Ana- tomie als bahnbrechend anzusehen ist, da er die Leichensektionen daselbst einbiirgerte. Der New York Academy of Sciences gestatten wir uns anbei den Abdruck eines Aufsatzes zu iiberreichen, welcher zu Ehren von Karl von Linn6 in der Leopoldina soeben erschien. A. Wangerin, Prdsideni.

Leider ist es mir bei der Flille von Arbeit, die vor mir liegt, nicht moglich, Ihrem Wiinsche [for a document to be read at the Bicentenary] zu entsprechen, aber Sie diirfen iiberzeugt sein, dass meine Gedanken und Wunsche am 23 Mai bei Ihnen in New York sein werden. Moge Ihr Fest den schonsten Verlauf nehmen und ein freundlicher Stern iiber der schonen Briicke walten, die den Namen eines der bedeutsamsten Begriinder der Naturwissenschaften tragen soil. Ihre Nation gibt der ganzen Welt ein nachahmungswiirdiges Beispiel, indem sie ein stolzes Werk der modernen Technik nach einem Forscher benennt, dessen ganzes Leben dem hochsten menschlichen Gute, der Wissenschaft, geweiht war. Regia Societas Scientiarum Bohemica, Prague. The Royal Bohemian Society of Sciences in Prague, fully appreciating the importance of celebrating the two hundredth anniversary of Carl von Linn^'s birth by the New York Academy of Sciences, is glad to join the sister institutions in honoring this great naturalist, whose efforts in the first splendid achievements and developments of biology are of perpetual value. When, in the beginning of modern times, in the multitude of known and newly discovered organic forms, there was a complete chaos to be feared instead of an exact distinction of them, it was the genius of Linn6 which arranged the masses of rav%' material into the scientific edifice of a strictly logical system. Linn6's epochal "Systema Naturae" laid the foundation for all future systematics of animals and plants. Introducing the descriptive method and terminology, establishing a clear definition of each species in its genus, order and class, Linne gained a firm basis for an exact deduction of organic forms. It was Linn6 who at the same time united the analytical and synthetical tendencies of his predecessors into an efficient discipline. Linn^'s method has facilitated the knowledge of the flora and fauna of whole territories, and we have to thank this method that also in Bohemia very early efforts for a systematical analysis of the organic world have been biviUght to full efficiency. The Royal Bohemian Society of Sciences, the oldest center of scientific 70 ANNALS NEW YORK ACADEMY OE SCIENCES efforts in Austria, has from the very beginning of her existence founded her work on Linne's teaching, and has in progress of time, with the increasing numbers of successful scientists amongst her members, continually contrib- uted to the systematical knowledge of organic life in Bohemia. We need only point out the old classical systematicians of zoology and botany, — M. E. Bloch, Von Stein, K. P. Presl, Lad. Celakovsky, and others who enriched the publications of the Royal Bohemian Society of Sciences in the spirit of Linne. And the researches of modern times, so important for the study of organic life in the enormous mass of its zoological and botanical forms, though they are far advanced in their ideas and methods, still must always gratefully remember the invaluable deseils of the great Linne for the foundation and development of biology.

The astronomers of the Specula recognize a close relation between their BICENTENARY OF LINN.EUS 71 own realm and that of the distinguished Swedish naturalist, in that stars and flowers are called the " eyes of the heavens " and the "eyes of the field," which, with the eyes of the child, are numbered among the most precious gifts of the Creator. We rejoice with you that Linne has unfolded to us the beauties and riches of the eyes of the field, which, no less than those of the heavens, show forth the crlors' of God. John G. Hagen, S.J., Director. fc> Reale Osservatorio di Palermo, Italia. Poiche in occasione del second© centanario della nascita di Carlo Linneo, che cotesta Accademia celebrera ii 23 corrente, la S. V. Illraa mi ha gentil- mente invitato a contribuire un document© ufficiale apprerzante I'opera del Naturalista Svedese, io, non avendo una competenza sufficiente per dire cosa degna di un cosi eminente Scienrato in una ricorrenza cosi solenne, mi sono rivolto per aiuto al mio illustre collega Prof. A. Borzi, direttore del R. Giardino Botanico e Coloniale di Palermo, il quale mi ha risposto con la lettera che qui Le hascrivo. "E'tanto diflBcile dire qualche cosa di nuovo su Carlo Linneo che io mi trovo imbarazzato a rispondere alia sua domanda. Da quasi due secoli tutte la vita di questo sommo Naturalista & stata indagata in ogni piii minuta particolarita, tutte le sue opere studiate con tanta profondita di dottrina, che io non saprei che cosa dire. Certamente di Linneo si puo affermare che nessun botanico o naturalista raggiunse a cosi alta fama come lyui: non v'^ persona mediocremente colta che non rammenti il nome di Carlo Linneo, mentre di tanti e tanti altri insigni naturalisti il ricordo non ha vareato cosi vasti confini. II piu grande merito di Linneo, second© me, non consiste r©lamente nell© avere riformato e piantato su basi incrollabili la sistematica vegetale, ma s©pra tutt© quell© di aver tracciato le linee fondamentali della Botanica Scientifica moderna divinandone meraviglio- samente i c©ncetti. Basta leggere il piccolo libro intitolato " Philosophia botanica" per convincersene. "Forse potra far piarere all' Accademia de New York il comunicarle un d©cumento inedito curiosissimo che interessa la storia del nostro Istituto Botanico a prop©sit© di Carlo Linneo. Quando nel 1792 si fondo I'Orto Botanico di Palermo fu eretta una statua in onore del s©mm© b©tanico svedese. Lo scult©re fu Vitale Zuccio, che la m©dell6 in istucco il doppio del naturalc. Qucsta statua fu copiata da un ritratto di Linneo, dal Linneo stesso giudicato il piii somigliante e doA^to al pittore Roslins. II Zuccio, 72 ANNALS NEW YORK ACADEMY OF SCIENCES scultore palermitano, non ebbe la occasione di vedere questa pittura, ma semplicemente una incisione eseguita dall' artista Bervic nel 1779. Im- portante per5 b il fatto che la prima statua eretta in onore di Linneo fu la nostra, mentre il primo ricordo marmoreo (un merzo busto) dell' insigne botanico, che si conosca, e quello che eresse il giardino delle piante di Parigi il 1790. La patria di Linneo ebbe al 1820 la prima statua dell' immortale suo figlio." lo mi un pregio di mandare a Lei una fotografua della statua di Linneo di cui ha partato il Prof. Borzi. F. Angelitti, Diretiore. Real Academia de Ciencias Ezactas, Fisicas y Naturales de Madrid. La Real Academia de Ciencias exactas, fisicas y naturales de Madrid estima como honrosa distincion el convite, que esa ilustre Academia le dirige, para contribuir a la celebracion del segundo centenario del nacimiento de Carlos Linneo. Gustoslsima se asocia k las solemnidades con que se festeje la veneranda memoria del naturalista, que, antes y mejor que otro alguno, supo imprimir orden, metodo y sistema al estudio y conocimiento de los seres naturales, dotdndo a la ciencia de una nomenclatura y de una nocion de las especies, base de todas las descripciones y agrupaciones de los seres vivos, posterior- mente aceptadas. Espafia se complace tanto mas vivamente en la exaltacion de la obra del sapientlsimo maestro sueco, cuanto que por intermedio de un discipulo suyo estuvo con ^1 en constante comunicacion mientras vivio. Fenga pues, la Academia de Ciencias de Nueva York por presente en esplritu a la Real Academia de Ciencias exactas, fisicas y naturales de Madrid, en todos los actos, con que el 23 de Mayo glorifique a Linneo. Josf; EcHEGARAY, El Ptesidente. Francisco de P. Arrillaga, El Secretario. Royal Cornwall Polytechnic Society, Falmouth, England. To the members of the New York Academy of Sciences and assembled guests, on the occasion of the celebration of the bi-centenary of the birth of Carl Von Linn6, the members of the Royal Cornwall Pol}'technic Society (England) send greetings. BICENTENARY OF LINN^US 73 As the parent of all societies calling themselves by the name Poljlechnic, and having from its birth, in 1832, consistently adhered to the purpose of its founders, viz., — the encouragement of science, as well as the fine and industrial arts, — the Royal Cornwall Polytechnic Society offers its congratu- lations to its fellow-workers in the domain of science in the great city of New York, on the practical and comprehensive character of the commemorative exercises which their enterprise and wisdom have projected for the interesting occasion falling on May 23 next. It trusts nothing will occur to prevent each function from realization in a manner befitting the memory of so great a benefactor to natural science, and fully sustaining the prestige of one of the foremost of the learned societies in America. While leaving it to societies of wider renown to express the world's indebtedness and gratitude to Carl von Linn6, who has been truly styled "the father of modern systematic natural history," and who v,^as the founder of the now universally adopted binominal system of scientific nomenclature, the Royal Cornwall Poljlechnic Society cannot, on this historic occasion, refrain from recording its own appreciation of the work accomplished by one who, though a distinguished son of Sweden, belongs, by virtue of his brilliant achievements, to every land and people. The careful and far-reaching character of the investigations of Carl von Linne probably stand without parallel in the annals of science. Sur- rounded in early life by conditions which would have deterred most men, genius and a whole-hearted enthusiasm for the pursuit of knowledge in a direction where he was destined subsequently to hold a position which, after the lapse of two hundred years, is still unique, his clear insight, added to his almost incomparable faculty for dealing with vast accumulations of material, enabled him, after years of constant devotion to his self-imposed task, to evolve cosmos out of chaos. The foundation which he laid for the determination of genera and species was the soundest that science had been invited to adopt, and on it succeeding generations have reared a noble structure. What the New York Academy of Sciences has been able to accomplish, what the Royal Cornwall Pohi;echnic Society has done for the encourage- ment of the many branches of natural science, v/hat is being done by kin- dred societies all the world over, has been made possible through the new era which was ushered in by the publication of the numerous erudite works from the pen of him to whom all nations are now paying homage. To-day we think of the student whose indomitable courage enabled him to triumph over difficulties of the most trying kind, and to fill his appointed niche in human affairs; of the man whose life was so devout that his first sight of an English furze-bush, arrayed in all its golden splendor, was to 74 ANNALS NEW YONK ACADEMY OF SCIENCES him fitting occasion for expressing gratitude to God; of the distinguished scientist on whom the world's greatest prizes had been freely showered, selecting one of the most unobtrusive of plants to perj^etuate his own name. After two hundred years, Carl von Linne enters into full possession of his own well-earned estate, an estate fixed deep and indelibly in the heart and affections of every student of nature. John D. Enys, President. E. W. Newton, Secretary. The Manchester Literary and Philosophical Society, Manchester, England. The Manchester Literary and Philosophical Society willingly joins with the New York Academy of Sciences in its commemoration of the two hun- dredth anniversary of the birth of the illustrious Linnaeus. His profound insight into the affinities and disresemblances of organized beings; his vivid differentiation of natural groups; his pithy, crisp charac- terization of orders, genera and species; and his binomial principle of nomen- clature, — all exercised a profoundly stimulating influence upon the progress of biological science. Nor must the personal merits of the man pass unrecognized. His acknowl- edgment of the work of his predecessors, his self-sacrificing labors, the en- thusiasm with which he inspired his students, and his remarkable humility — so fittingly commemorated in the Linnoea borealis — are qualities which provoke the admiration of naturalists, alike in the hemisphere in which he worked and in the hemisphere in which this commemoration is being held. Harold B. Dixon, President. Francis Jones, 1 Honorary Frederick William Gamble, j Secretaries. Professor James Geikie, University of Edinburgh. (Honorary Member of the Academy.) 1 deem it a high honor to be invited to place a little stone on the ever- increasinff cairn raised by lovers of science all the world over in memory of Carl von Linne. The distinguished Swedish naturalist has made a name for himself that can never die. Admirable as an exact observer and care- ful collator of evidence, and no less admirable as a generalizer, he is an ensample to every sincere student of nature. Before this bright genius BICENTENARY OF LINNMVS 75 appeared, the study of natural science was in a more or less chaotic state. Doubtless much knowledge of living things had been acquired before his time, but hitherto that knowledge had not been systematized. It was reserved for Linne not only greatly to increase the stores of learning, but to indicate how it was possible to group and classify the multitudinous forms of life so as to show that all formed part of one grand harmonious whole. One can hardly exaggerate his influence upon the study of the natural sciences. His was one of those creative, fertile minds from which all who made his acquaintance, either personally or through his writings, were bound to catch inspiration. He must have had a most engaging personality, and was undoubtedly filled with enthusiasm. How otherwise could he have drawn annually to Upsala some fifteen hundred pupils from all parts of Europe? His "Systcma Naturae," "Genera Plantarum," "Critica Bo- tanica," and other famous works, are unquestionably notable landmarks in the history of natural science. Science and their influence we can to some extent estimate ; but who can estimate the profound influence he must have exerted on the many thousand pupils who listened to his prelections, and who carried his enthusiasm with them into every civilized country! Hon- ored and admired in his own day, Carl von Linne will ever continue to be recognized as one of the foremost men of all time. The Royal Society of Canada. The President and Fellows of the Royal Society of Canada beg to offer their cordial thanks to the New York Academy of Sciences for its kind invitation to participate in the exercises commemorative of the two hundredth anniversary of the birth of Carl von Linne, and express their regret that they are unable to send a delegate to personally represent their Society on this most Interesting occasion. The Royal Society of Canada, which has just closed its Twenty-fifth Annual Meeting, shares with the New York Academy of Sciences and with kindred associations all over the world, in its high appreciation of the eminent services rendered to the natural sciences by the transcendent ability, judg- ment and foresight so remarkably displayed by the distinguished Swedish naturalist of the eighteenth century. To him is due in no small measure the modern system of scientific nomenclature, and by him were laid the foundations of the classification of animals and plants upon which biologists in all departments have since built their structures of scientific knowledge. It is therefore In the highest degree fitting that the name of so great a man as Linne, the precursor of a long line of eminent philosophers, should be 76 ANNALS NEW YORK ACADEMY OF SCIENCES honored in America in the manner that is now proposed, and that the beauti- ful bridge connecting the Botanical Gardens and the Zoological Park in New York should by its name perpetually remind the passer-by of the great- ness that may be achieved by intellectual and scientific attainments. In an age that may be considered sordid in many of its occupations and aspira- tions, such a reminder is of great value, and may lead many to think of the man, and endeavor, in however humble a manner, to tread in his footsteps. All honor to the name of Carl von Linne! May the torch which he kindled with the flame of natural science, which has illuminated the path of numberless followers during two hundred years, never be extinguished! May we all strive by our diligent work, by our enthusiasm, by our lofty aims and high hopes, to keep it alive and pass it on, ever growing more and more brilliant, to those who shall come after us! Wm. Saunders, President. The Entomological Society of Ontario. The President and Officers of the Entomological Society of Ontario are pleased to have an opportunity of adding a few words, to the many which will be read at the commemorative exercises which are to be held on the 23d instant, in appreciation of the magnificent work which was done for the whole world of science by Carl von Linne, the founder of systematic natural history. It is, however, with deep regret that we find it impossible to send a delegate to take part personally in this celebration. By entomologists and botanists especially, the name of Linne must always be held in reverence and respect, for to him is in large measure due the placing of these branches of natural history on a stable and permanent foundation. He was indeed the father of systematic biology; and the mem- bers of our Society feel that too much honor can never be bestowed upon the memory of so great a man. It is therefore a cause of much gratification that a lasting monument in the shape of a beautiful bridge crossing the Bronx River has been erected, which will be a constant reminder to all visiting the Botanical Garden and Zoological Park of the work which was done by this master mind. James Fletcher, President. Charles J. S. Bethune, Secretary. BICENTENARY OF LINN^US 77 Sociedad Cientifica "Antonio Alzate," Mexico, D.F. By request of the Sociedad Cientifica "Antonio Alzate" of the City of Mexico, I have the honor to represent that distinguished Society as its delegate to the New York Academy of Sciences on the occasion of the exercises commemorative of the two hundredth anniversary of the birth of Linnaeus. The Society Antonio Alzate, which represents the scientific thought of the Republic of Mexico, is composed of men of high attainments, many of whom, through the important official publications of the Society and through other media, have made rich contributions to the sciences of botany, zoology, chemistry, astronomy and other branches of learning. These enlightened men are in full sympathy with the most advanced men of science in the United States. The members of this important Society are fully imbued with the Lin- nsean spirit, and are animated by the same desire to emulate the great example of the master that inspires their New York brethren. By the instructions of the Society Antonio Alzate I bring the friendly greetings and hearty sympathy of its members to the New York Academy of Sciences as it celebrates this interesting and notable anniversary. George T. Stevens, Delegate. The Museum of Comparative Zoology, Harvard University. The Museum of Comparative Zoology in Harvard University accepts with pleasure the invitation of the Academy to participate in the exercises commemorative of Linnaeus, and it has requested Mr. William Brewster, a member of its staff, to represent it upon that occasion. Linnaeus embraced the whole department of natural history in its widest sense. His conspicuous contributions to botany have much obscured the fact that ever}' field of nature was investigated by him with productive results. Throughout the entire range of inorganic and organic nature he passed with steady step, introducing methods of study and systems of terminology which brought order out of confusion. Recognizing the indebtedness which all natural science owes to Linnaeus, our Museum joins in the tributes which at this time the whole world is pay- ing to his name. Charles W. Eliot, President. Alexander Agassiz, Secretary. 78 ANNALS NEW YORK ACADEMY OF SCIENCES The Boston Society of Natural History. The Boston Society of Natural History, through its official representa- tive, Mr. Joel Asaph Allen, sends its greetings and congratulations to the New York Academy of Sciences, and desires to share in the celebration of the two hundredth anniversary of the birth of Carl von Linn^. Upon the basis of the scientific achievements of the great Swedish naturalist, all subsequent work in botany and zoology has been built up. To his labors and to the system introduced by him, we owe the possibility of recording, and thereby mastering, the immense and bewildering flora and fauna of the world. Our debt to him can hardly be overestimated: there- fore the Boston Society of Natural History is glad to add its tribute of admi- ration and gratitude, and begs to thank the Academy for the opportunity of participating in the present noteworthy celebration. Charles Sedgwick Minot, President. The Connecticut Academy of Arts and Sciences. The Connecticut Academy of Arts and Sciences gratefully accepts the invitation of the New York Academy of Sciences to participate in the commemorative exercises to be held on the two hundredth anniversary of the birth of Linnseus. The Academy appreciates the lasting influence which his work in botany and zoology has exercised on the development of these sciences throughout the whole world. Through his profound studies he was enabled to bring order out of the chaotic writings of his predecessors, to establish the science of taxonomy on a firm and satisfactory basis, and to prepare the way for a natural and logical classification of plants and animals. The Academy has the honor to appoint Professor Alexander W. Evans as its authorized representative. A. E. Verrill, President. George F. Eaton, Secretary. The American Journal of Science. The editorial staff of the "American Journal of Science" — whose birth in 1818 was contemporaneous with the beginnings of natural science in this country, and which for nearly a century has kept pace with the growth of t BICENTENARY OF LINNAEUS 79 science, and ever striven to support and stimulate it — desires to express to you its profound appreciation of the debt we all owe to the great Swedish naturalist whose birth in 1707 you commemorate. If science is classified knowledge, the highest credit belongs to him Avho brings scientific facts and observations into a rational system: in this work Linnaeus stands pre-eminent. To his keen mind it w^as given not only to bring order among the genera and species of plants and animals, not only to build up a lasting system of nomenclature, but also to develop in these directions, as in the broader relations, a profound basis of classification which has had a lasting influence upon science in all its branches. Edward S. Dana, Editor-in-chief. The Torrey Botanical Club, New York City. A clearly-stated conspectus of contents and an index so arranged that one may consult the contents with a minimum of labor are two crowning features of any volume. They reveal a systematic as well as a constructive intelli- gence on the part of the author, and mark the boundaries between chaos and clearness. It is with this feeling that botanists look back to Linnseus, not so much for the originality of his research as for his gift of order, by means of which the unclassified botanical observations of two centuries were reduced to a system. It matters not that this system perished almost in a generation; it served a purpose in its own day, and made progress possible to those who had previously been wandering over a boundless sea with neither stars nor sun to guide them. Linnaeus is remembered, not because of his research, but because of his arrangement of existing knowledge in a usable form. In spite of his blunders (for he was not free from them), in spite of his arbitrary substitutions of his own work for the clearer work of others, in spite of the fact that he emphasized system at the expense of the broader principles of comparison, and withal contributed to the fixing, for five generations, the dogma of constancy of specific characters, — botanists will always regard Linnaeus as one of the truly great. He was the "father of botany," not even its elder brother. He was not the author of binomial nomenclature, for that originated before Linnaeus was born; he was the first who was able to look at the existing knowledge of plant life with some degree of perspective, and he reduced that knowledge to a system, that botany might later become a science. LuciEN M. Underwood, Committee. 80 ANNALS NEW YORK ACADEMY OF SCIENCES New York Entomological Society. IN MEMORY OF CAROLUS LINN^US, 1707-1778. The name of Linnseus, the illustrious naturalist who first pointed out the real utility of some system by which the great kingdoms of nature could be systematically arranged, is known to the whole civilized world. Linnseus was not only a naturalist of most accurate observation, but of a philosophical mind, and upon this depended in a great degree the unpar- alleled influence which he exercised upon the progress of every branch of natural history. If we consider the difficulties which beset his early scientific career, the limited number of collections of animals and plants at his command, we must admit that the merit which his contemporaries awarded him was very justly earned. Among the important services which he rendered to science was the creation of a natural system of classification and the introduction of a more precise nomenclature, which in the main is followed to-day. While quite young he received his first inspiration for natural history in his father's garden, A\'hich was planted with many rare shrubs and flowers. Those sparks which were kindled in the early part of his life at last burst into such a flame of intensity, that the marks are indelibly left upon the sciences. Entomology owes much to the work of this great man. In his "Systema Naturae" (tenth edition), he divided the insects into seven orders, as follows : Coleoptera, Hemiptera, Lepidoptera, Ncuroptera, Hymenoptera, Diptera and Aptera. The modern orders Forficulidae and Orthoptera were placed with the Coleoptera; the order Thysanoptera, with the Hemiptera. The order Neuroptera included the modern orders Ephemerida, Plecoptera, Isoptera, Corrodentia, Platyptera, Neuroptera, Mecoptera, Trichoptera and Odonata. The order Aptera contained all the insects without wings or elytra, except the females of Mutillidse, including also those arthropods which form to-day the classes of Arachnida and Myriapoda. Each order contained a small number of genera which were not arranged into families. Of the many insects described by him, about three liundred species occur in the United States, most of which were originally described from Europe, and some from South America. Of the different orders repre- sented, Linnseus described seven species of Neuroptera, four species of Odonata, twelve species of Orthoptera, twenty-seven species of Hemiptera, BICENTENARY OF LINN^US 81 a hundred species of Coleoptera, fifty species of Diptera, twenty-eight species of Hymenoptera and sixty-six species of Lepidoptera. The New York Entomological Society appreciates this opportunity of paying tribute to the memory of the man through whose wonderful far-sight and scientific attainment we are better able to understand the great system of nature.

It has been said by Taine that "every book and every man may be reviewed in five pages, and those five pages in five Hnes." On this occasion, however, we are not asked to review the Hfe or the books of the man in whose honor we are assembled, but to testify as briefly as may be to our appreciation of his work and what this work has meant to his posterity. Such a task is different from that which the reviewer is ordinarily called upon to perform; and to do it justice in words, within a reviewer's recognized limitations, would be impossible in connection wuth the name of Linnaeus. Fortunately, however, words are not necessary, and indeed are superfluous, where this appreciation is so clearly demonstrated in the fact that we accept the prin- ciples which he formulated, and pursue the methods which were his, in all of our scientific activities. By merely recognizing and calling attention to this fact, we show our respect for the man and v.iiat he has wrought far better than by even the most earnest and sincere attempt to express our sentiments in words. Consciously or unconsciously the influence of Linnseus is felt by all modern scientific workers. System, or rather the ability to systematize, is the key to progress in all lines of human endeavor; and science in particular owes its present commanding position to those who have recognized and applied the principles of Linnaeus in their work, and v/ho have accepted and applied his rules for the nomenclature of natural objects. Linnaeus was pre-eminently a systematist, and it was this habit of mind, more than an}i;hing else, wdiich raised him above his contemporaries in science. Without his masterly ability to co-ordinate and arrange his work in logical sequence and coherent groupings, his great powers of observation would have lacked completeness. This ability was the special characteristic which enabled him to revolutionize the scientific work of his age and to influence so profoundly all that has followed. To Linnaeus may well be applied the words of Bourget: "In life every- thing is unique, and nothing happens more than once." Arthur Hollick, Delegate. New York State Museum. Linn^'s contributions to systematic biology are brilliantly exemplified by one of his species of fossil brachiopods, the Anomites reticularis. No organism which ever appeared in the long history of the earth has had a 86 ANNALS NEW YORK ACADEMY OF SCIENCES career so noteworthy for the stability of its specific characters. It made its d^but in the Midsilurian era, and thence onward it survived through the long ages of the Devonian and into the Carboniferous, without at any time departing from the specific type. Anomites reticularis stands as the ideal of conservatism, the very shib- boleth of heredity. Nature's ultimate expression of stability in the organic world. Its life was the longest that ever fell to the lot of organic species; its period beheld the rise and fall of many another race ; an endless procession of creations saluted it and passed on, as we to-day, after two hundred years, salute the great Swede, and pass on to join the multitude. John M. Clarke, Director. The BufEalo Society of Natural Sciences. The Buffalo Society of Natural Sciences, in expressing its thanks to your honorable Society, and its appreciation of its privilege in being permitted by your courteous invitation to share in your celebration of the two hundredth anniversary of the birth of Carl von Linne, desires to add its tribute of praise to the memory of that great reformer in the work of natural science. The world must ever be grateful to Linnaeus for the wonderful knowledge, born of close and accurate observation, and for the clear vision and admirable judgment which enabled him to index the book of Nature, to substitute order for confusion, and, by the judicious simplicity of the laws laid down by him in his methods of classification, to convert, what before his time had been chaotic, into the orderly ways that characterize the modern systematic study of botany and biology. To him and to his work we turn as the starting-point for these scientific studies which since his day have been so nobly developed by those who have been his successors. Though his system may have been superseded by the philosophical conclusion of other famous workers in botanical science during the past two centuries, the revolution which he wrought in that great department of nature study, the lucidity and simplicity of the reforms in method which he first proposed, have crowned him as one of the greatest leaders known to the annals of science, and as such we honor and revere his memory. We ask you to accept our felicitations on this interesting occasion. T. Guilford Smith, President. Carlos E. Cummings, Secretary. BICENTENARY OF LINNMUS 87 The American Philosophical Society. The American Philosophical Society held at Philadelphia for Promoting Useful Knowledge sends cordial greetings to the New York Academy of Sciences on the occasion of the celebration of the two hundredth anniversary of the birth of Carolus Linnaeus. Out of the mechanical and inorganic systems of ancient and mediaeval times this great Swedish naturalist constructed an organized system, which, assisted by the binomial nomenclature, established order and system in the natural sciences. This system has guided clearly the mind of man in the classification of natural objects, and has made the name of its author immortal. In the year 1770 The American Philosophical Society, in recognition of the valuable services Carolus Linnaeus rendered to science, elected him to its membership, and now, a hundred and thirty-seven years later, this Society takes pleasure in uniting with the New York Academy of Sciences in doing honor to his memory. Signed and sealed on behalf of The American Philosophical Society held at Philadelphia for Promoting Useful Knowledge. Edgar F. Smith, President. J. Minis Hays, Secretary. The National Academy of Sciences, Washington, D.O. I am directed by President Ira Remsen of the National Academy of Sciences to convey the greetings and congratulations of the National Acad- emy on this occasion of the celebration of the two hundredth anniversary of the birth of Linnaeus. I desire to present a brief appreciation of Linnaeus from the standpoint of comparative anatomy and classification of the mammalia. The period of Linnaeus was that of his active scientific life, between 1730 and 1795. Linnaeus did not introduce the term "Mammalia" until the tenth edition of the "Systema" (1758). In following the suggestions of Ray, Bernard de Jussieu, and, it is also claimed, of Blumenbach, he sepa- rated the hairy quadrupeds, the manatees and whales, as a single class, noting among the distinctive characters the position of the mammae and the hairy covering. His education as a physician qualified him to define the class through the internal anatomical characters, — the heart, the lungs, the sense organs, — as well as through external characters. In arranging 88 ANNALS NEW YORK ACADEMY OF SCIENCES the mammals he sought for natural groupings, and endeavored to find the hidden bonds of structural affinity as indicated by comparative anatomy, although he did not recognize that the real basis of affinity is to be found in kinship of evolution from similar ancestral forms. His scientific independence and genius were indicated especially by his inclusion of man with the apes and monkeys in the order Primates. It was a mark of genius that Linnaeus felt the force of the anatomical likeness of man to his lower relatives and that he had the courage to definitely ally him with them from a strictly zoological view-point. This is the very starting- point of all modern philosophy, that man is linked by ties of blood kinship to the whole organic world. That Linnaeus's system is based in part on adaptive resemblances or analogies, rather than on structural affinities or homologies, is not surprising, because it is only recently that naturalists have been able to distinguish analogies from homologies. Henry Fairfield Osborn, Delegate. The Smithsonian Institution of Washington, D.O. The Smithsonian Institution, uniting with the New York Academy of Sciences in its appreciation of Carl von Linne, cordially accepts its invitation to participate in exercises commemorative of the two hundredth anniversar}' of the birth of the great Swedish naturalist. The Smithsonian Institution, in response to the invitation to take part in the Academy's celebration of the bicentenary by an appreciative record of the work of von Linn6, needs only to recall the great impulse which he gave to natural science by his industry and methods, and the facility for expression of facts by his binomial system of nomenclature. But the philosophic generalization which was recorded in the name of Mammalia may be espe- cially recalled as the greatest morphological triumph of the Linnsean era. Chas. D. Walcott, Secretari/. The Biological Society of Washington, Washington, D.C. The Biological Society of Washington acknowledges with pleasure the invitation of the New York Academy of Sciences to take part in its cele- bration of the two hundredth anniversary of the birth of Carl von Linn6, and is glad to unite in paying fitting tribute to the memory of the man who is justly regarded as the father of the biological sciences. BICENTENARY OF LINNJEUS 89 It is, in fact, scarcely possible to overestimate the influence his work and personality had in shaping the future of botany and zoology; and coming generations of biologists will continue to rejoice, as we now do, that he laid the foundations of their science so deep and so broad. The vocabulary of superlatives to praise his genius has long since been exhausted; but we who daily and hourly profit by the laws he enunciated may well pause in our work to exult because, two hundred years ago, Sweden gave to the v.^orld a light that will continue to shed luster upon her name so long as the biological sciences exist. Leonhard Stejneger, President. Wilfred H. Osgood, Secretary. The Indiana Academy of Sciences, Indianapolis, Ind. The criterion by which a man's greatness is judged is his work. If this gains recognition from his contemporaries, he is successful; if his name lives to be honored by succeeding generations, his career has been more than successful, he has achieved fame ; but, if he leaves behind him some piece of work or the record of some discovery from which his successors reckon time, his is a distinction which comes to few men, and to which none dare aspire. Such is the record of Linnaeus. He was a recognized leader among his contemporaries; his co-ordination of the chaos which then existed in the natural sciences gave him fame ; and the successful application of the bino- mial system of nomenclature to animals and plants made his works the point from which the taxonomist measures time. Nor is the homage the expression of the whim of a group of hero-worshipers. To-day the system of Linnseus is discarded by taxonomists, and much of his work is forgotten; but as long as systematic botany and zoology have their devotees among men of science, so long will his name be remembered and his fame endure as the one who first brought the binomial system of nomenclature into general use. Guy West Wilson, for the Academy. The Colorado Scientific Society, Denver, Colo. The Colorado Scientific Society, the oldest and largest scientific associa- tion of the Rocky Mountain region, sends greeting to its elder sister in the metropolis of America, and extends congratulations on the successful com- pletion of the memorial in honor of the world's greatest botanist. How great must be the power of the savant whose influence can extend over QO ANNALS NEW YORK ACADEMY OF SCIENCE such great gulfs of space and time as those which separate the sage of Upsala from the naturalists of the Rocky Mountains, the lands of the midnight sun from the dome of the North American Continent, the dawn of the eighteenth from that of the twentieth century ! In common with the rest of the scientific world, we are greatly indebted to him who initiated the modern system of a concise and descriptive nomen- clature, to him who found "biology a chaos, and left it a cosmos," and to him who made it possible for finite minds to grasp the thoughts of the Infinite in the world of life. Colorado is especially indebted to Linnaeus from the fact that, owing to the general similarity of our Alpine flora to the plants of the Scandinavian Alps, a large portion of our mountain plants was originally described by the father of botany, and so well classified and described, that the notoriety- seeking, hair-splitting species-makers do not venture to meddle with the work of the master hand. We are proud of the fact that on the snowy summits of our higher peaks grows in abundance the tiny pink-tipped flower which the innate modesty of the true savant led him to select from all the wealth of the floral world to perpetuate his name in coming generations.

PART II.* new v/^». POT AT By John B. Smith, Sc.D. oa^ocn. No branch of zoology has profited more by the explorations and collec- tions made during the past decade than entomology. Not only have new species been found in localities collected over for the first time, but, as the result of more thorough investigation of the fauna of older regions, we have learned that mere resemblance to species of other faunal regions does not mean necessarily specific identity. With more abundant material, our conception of the limits of species became more accurate, and definition became possible. In the Canadian northwest a quite distinct noctuid fauna is becoming gradually known, and in the southwestern portion of our own territory the canyons are yielding not only specific but also generic types heretofore unknown. For some time past, material has accumulated gradually in my collection which could not be referred satisfactorily to known or described species, — sometimes in single examples only, sometimes in small series, — and this has increased gradually to such an extent as to demand a general clearing-up, although descriptive work of this kind is perhaps the least attractive to the true student. Viridemas nov. gen. Head retracted, small; front with an upright, blade-like corneous process, which reaches to the end of the short, rough vestiture, and does not modify the general impression of a fiat head. Palpi very short and weak, not extending beyond the edge of the front. Tongue weak, not functional. Eyes large, round, naked, not fringed with lashes. Antennse of normal length; those of the male -n-ith the segments marked and the projecting angles set with .short bristle-tufts, those of the female simple. Thorax short, quadrate; collar round, flat; patagia well marked, ' Part I of the descriptive papers for 1907 is in the Transactions of the American Entomo- logical Societ5', Vol. XXXIII, pp. 125-143, where twenty-nine species are described. In the present paper forty-seven species are characterized and four new generic terms are proposed. The types are in most instances in the author's collection at Rutgers College, New Bruns- wick: a few of them are at the Museum of the Brooklyn Institute of Arts and Sciences. I 91 92 ANNALS NEW YORK ACADEMY OF SCIENCES a little uplifted; vestiture scaly with an admixture of flattened hair, forming, pos- teriorly, a large mass, which is scarcely a definite tuft. Legs short, middle and hind pairs sub-equal in length; tibise unarmed, not spinulate, in the male clothed with a mass of rough scales and hair. Abdomen stout, well exceeding the second- aries; in the female, stout, sub-equal and sub-cylindrical, obtusely terminated, with a prominent little tuft on the third dorsal segment. Primaries trigonate, rather broad; apex well marked; outer margin arquate, oblique; hind angle rounded; venation normal; accessory cell present, giving rise to 7, 8 -I- 9 and 10 from its end. Secondaries proportionate, with vein 5 obsolescent. Viridemas galena nov. sp. Ground-color ashen gray, powdery. Front with an admixture of brown scales. Collar with an obscure median line and an admixture of bluish-green scales. Patagia with disk clothed with green scales, and with a blackish sub-marginal line. Pos- terior scale-mass bronze-brown. Abdomen dark gray, the posterior margins nar- rowly light gray. Primaries with all the usual maculation traceable, but obscured by the powdering of dark scales. Basal space green-powdered, and on this the short, single, black basal line is fairly defined. T.a. line black, single, upright, a little irregular. T.p. line single, black, slender, discontinuous, a little lunulate, well exserted over the cell and almost as much incurved below, followed in the sub-median interspace by a conspicuous greenish- white blotch, which is the most obvious feature in the maculation. There is a broken, black median line, which extends along the inner margin of the reniform, and below it to the margin. S.t. line whitish, diffuse, powdery, discontinuous, partly defined inwardly by black scales, which give the line a jagged appearance. A series of black terminal lunules is followed by a pale line at base of fringes. Claviform a broad, black-ringed loop, extending about one-third across the cell and as broad as long. Orbicular large, round, gray, ringed by black scales, a little darker centered. Reniform large, gray, not defined above or below. Secondaries gray, with a dark, lunate terminal line. Beneath, gray, powdery, with a broad, diffuse exterior line and a lunate diseal spot, which tends to become obscure on the primaries. Expands 1.16-1.32 in. = 29-33 mm, ^ Habitat: Huachuca Mountains, Arizona, VII, 30; Palmerly, Cochise County, Arizona, VII. Two males and one female, in fair condition. The males are purchased specimens from my oAvn collection, the female is from the collection of the Brooklyn Institute. A perfect, fresh specimen will show undoubtedly a considerably greater admixture of green, and, on the other hand, in old specimens the green tends to become dull and to mingle with the gray base so as to become inconspicuous except under a lens. Meleneta nov. gen. Eyes hairy, without overhanging lashes. Head moderate or rather small, applied very closely to the thorax; front very flat, quadrate, clothed with short. SMITH, NEW NOCTUID^ 93 divergent, hairy vestiture. Palpi very short, straight, extending scarcely beyond the frontal margin; second joint with long hair below; third joint as long as second; cylindrical, truncate. Tongue functional, well developed. Antennae of male thick- ened, the joints marked by impressed rings, without vestiture of any kind. Thorax quadrate, rather small; collar round, not produced; patagia well defined; vestiture coarse hair, not forming obvious tufts. Legs rather short; tibiae clothed with dense, long, coarse hair, not armed or spinulated Abdomen with long tufts of fine hair laterally at base, and with small, indefinite dorsal tuftings. Primaries trigonate; costa arched; apex marked; outer margin arquate, decidedly oblique; hind angle obtusely rounded: veins 7 to 10 out of the end of the elongate accessory cell; 7 and 10 from the lower and upper angle respectively; 8 and 9 on a stalk from the middle, between the two. Secondaries with vein 5 as strong as the others, out of the cross- vein not far removed from 4. This is a genus related to Raphia, with similar wing and body structure; differing in the antennee, character of vestiture, and absence of the charac- teristic tuftings. Only males are at hand, unfortunately, and the above characterization is drawn from that sex alone. Meleneta antennata nov sp. Deep bluish gray, the markings black or blackish. Head with vertex black; collar black-tipped; edges of patagia and dorsum black-edged. Antennse deep chrome-yellow. Primaries with the normal marking well defined. Basal line black, geminate, included space gray, and with a gray patch just outside. T.a. line gemi- nate, outer portion most obvious, almost upright, accompanied by a paler gray shade. T.p. line less definitely marked, geminate, the inner portion reduced to scattered black scales, the outer portion more continuous, but diffuse and irregularly defined, with an even outcurve over the cell and almost straight below. Median shade blackish, diffuse, darkening the space between the ordinary spots. S.t. line very irregular, pale, preceded by a black shading, which is best marked on the costa and below vein 2. There is a narrow, black terminal line, and the fringes are con- colorous. There is no obvious claviform, but there is a little jog in the t.a. line where it should be, and beyond is a rusty brown patch that extends to the median shade. Orbicular small, round, with a distinct black ring and an equally distinct black central dot. Reniform rather large, oblique, narrow, centrally a little con- stricted, narrowly black-ringed, gray with a white central line. Secondaries white, with a blackish terminal line which extends from the apex halfway to the inner angle. Beneath, primaries blackish, costal and outer margin with white powder- ings; secondaries white, costal margin with black powderings, a blackish terminal line from apex halfwaj' to the inner angle. Expands 1.25-1.40 in. = 31-35 mm. Hahilat: Huachuca Mountains, Arizona, VII, 30; Palmerly, Cochise County, Arizona, VIII. Two males, in good condition; one of them a purchased specimen, the collector unknown; the other from the collection of the Brooklyn Institute, 94 ANNALS NEW YORK ACADEMY OF SCIENCES taken by Mr. Carl SchsefTer. The species is quite characteristic, and I am sure that I have seen it in another collection. Acronycta othello nov. sp. Ground-color whitish ash-gray with sooty black shades and markings. Head, vertex black except at sides. Collar mostly black or sooty. Disk of thorax and margins of patagia black or sooty. Abdomen smoky gray above, whitish below; ba.sal tuftings black or sooty; edges of segments narrowly white. Primaries with a broad basal space rather evenly washed ^vith thin blackish over a bluish-gray base. T.a. line geminate, black, moderately outcurved and oblique, and ^ith outcurves iu the interspaces. T.p. line geminate, black; outer line most distinct, denticulate, with well-marked outward teeth on the veins; as a whole, well curved over cell and deeply drawn in below. There is no obvious s.t. line. The outer part of the median space above median vein is filled with blackish, and below this vein the entire space is sooty black, but not contrasting or intense. The outer part of the \\ing is gray, the veins blackish-lined, and a sooty black streak from t.p. line to hind angle just below vein 2. The fringes are cut with sooty brown on the interspaces. Orbicular a small black circle which may be obscured by a shading from the t.a. line. Reni- form moderate or small, lunate, incomplete, obscured by the median shade. Second- aries in the male white, in the female washed with smoky gray. Beneath, whitish, powdery, the primaries darker (darker in the female than in the male) ; secondaries with a small, blackish discal spot. Legs smokj', annulate, with white at the joints. Expands 1.75 in. = 44 mm. Habitat: San Diego, Cal., Sept. 15. One male and one female, in good condition; from Mr. Frank A. Merrick. The species is allied to perdita, but is obviously distinct by the absence of basal streaks and by the soft gray and black shadings. Acronycta lepetita nov. sp. Ground-color pale bluish gray with an olivaceous shading. Palpi black at sides, a black dot at base of antennae. Primaries with black basal streak extending to the t.a. line; a slight spur inferiorly at about the middle, a longer narrow branch on the upper edge, which reaches the t.a. line. A slender black streak crosses the t.p. line in the sub-median interspace, and extends to the outer margin. The basal line is indicated by an olivaceous costal spot. T.a. line geminate, olivaceous gray, very oblique, so as to reach the inner margin almost at middle. T.p. line geminate, outer line black, included space whiter than ground, somewhat squarely exserted over the cell and only moderately incurved below. S.t. space beyond the t.p. line is more olivaceous shaded, and this is best marked on the cost a and over the black streak above anal angle. A series of terminal black points on the %eins. Median shade ob\nous on costa, oblique over the reniform, which it darkens, and then lost. Orbicular oval, oblique, concolorous, narrowly outlined bj' black scales. It may or may not touch the reniform; but, when it does, the junction forms an obvious, curved black mark. Reniform large, broadly lunate, somewhat irregular, a little SMITH, NEW NOCTUIDM 96 dusky, incompletely outlined by blackish scales. Secondaries smoky, paler at base, the fringes whitish. Beneath, whitish, the primaries smoky on disk; both wings with discal marks and more or less obvious extra-median lines. Expands 1.05-1.10 in. = 26-28 mm. Habitat: Esper Ranch, Brownsville, Tex. One male and one female, in good condition; from the collection of the Brooklyn Institute of Arts and Sciences. The species is allied to vinnulu and paupercula, but is smaller than either and much more delicately marked. Comparatively, also, the primaries of the new species are shorter and broader. Noctua larga nov. sp. Head and collar bright rusty brown, the head darker in shade. Thorax brown with a more or less marked rusty tinge. Primaries gray-brown with a reddish tinge, varying in the specimens. All the lines single, punctiform. Basal line marked only on costa and in the cell. T.a. line with black venular spots and a scattering of black scales that marks the line across the costal region. T.p. line even, marked by distinct black dots on the veins, in course parallel to the outer margin. S.t. line wanting. A series of black, inter-spatial terminal dots. Claviform vaguely indicated by scattered black scales. Orbicular indicated by a few black scales, or altogether wanting. Reniform marked by a black dot and a variable number of black scales; not complete, or even so outlined as to make out a definite form, in any case. Secondaries pale at base, outwardly dusky, darker throughout in the female. Beneath, primaries smoky, secondaries whitish, both darker in the female. Expands 1.80-2.10 in. = 45-52 mm. Habitat: Palmerly, Cochise County, Arizona, August; Huachuca Mountains, Arizona, June 16. Three males and one female, in good condition; from the Museum of the Brooklyn Institute. The specimens were taken by Mr, Carl SchajfTer, who says they were commonly found under shelter, much as our clandestina are sometimes found in large numbers. There are other rubbed examples in the Museum collection; but all seem to be very much alike. The large size and simple markings, allied to those of clandestina, distinguish the species. Rhizagrotis acclivis Morr., Ann. Lye. Nat. Hist., N.Y., XI, 93, Agrotis, 1875; reclivis Dyar, Jour. N.Y. Ent. Soc, XV, 106, Rhizagrotis, 1907. Mr. Morrison's specimen came from New York and the type is in the Tepper Collection. About the same time, Dr. Harvey described Agrotis opaca, from Texas, and in 1890 I recorded my belief that the two gentlemen had named the same species. I had, then and later, examples from Texas, 96 ANNALS NEW YORK ACADEMY OF SCIENCES Arizona and Colorado, and, as the type of maculation and structure was unusual for the eastern fauna, I questioned whether the locality of the specimen in the Tepper Collection might not be erroneous. An examination of Dr. Harvey's type in the British Museum confirmed my belief; and in my Catalogue of 1903 (Bull. 44, U.S. Nat. Mus., 79) I cited the two names as referring to the same species, and gave the New York locality with an " ( ?)." Until 1907 I did not see another eastern example, though I had a number from southwestern localities. In a miscellaneous lot received from Dr. Dyar for determination, there was an example which I named acclivis, and to which I appended the note quoted by Dr. Dyar: "The first authentic specimen I have seen from this region. It indicates that the Nev/ York locality which I questioned in my Catalogue may have been correct, or it may indicate two very similar species which I have not had material enough to discriminate." Dr. Dyar did have material to discriminate, and he gives the differences between the eastern and the southwestern forms; but in giving a name he re-describes the eastern form that served Morrison as a type, and therefore creates a synonym merely. I assume that Dr. Dyar is correct in determining that there are two species, though I have not been able to verify that point; but, if this is so, it simply means that Dr. Harvey's name must be restored to the list and that the southwestern specimens now labeled acclivis Morr. in collections must be re-labeled opaca Harvey. Euxoa cocklei nov. sp. Head, thorax and primaries dull brown, varying from chocolate to smoky, and more or less irrorated with black. Collar with a more or less marked black median line. Disk of thorax and patagia with a sparse admixture of yellow scales. Prima- ries with all the maculation traceable, and usually v/ell written. Basal line geminate, black, included space yellowish. T.a. line geminate, included space yellow, the edgings black; upright to median vein outcurved in the space below and outwardly bent below vein 1. T.p. line geminate, inner portion lunulate, not well marked, outer portion hardly distinct; the included space yellowish, variably marked and not always continuous; in course moderately outcurved over the cell and then par- allel with outer margin. S.t. line a little irregular, broken, yellomsh, sometimes reduced to scattered yellow scales. A series of dusky terminal lunules, which are rarely distinct. There is a tendency to a darkening below the median vein, between the basal and t.a. line, and in one example there is a distinct black line. Claviform moderate, black-bordered. Orbicular round or oval, moderate in size, with a nar- row black edging within which is a ring of whitish scales. Reniform moderate in size, kidney-shaped, edged with black scales, then with an inner (more or less incomplete) border of yellowish; the spot sometimes darker inferiorly. Secondaries •smoky yellowish, almost uniform, with an obscure dusky lunule. Beneath, dull SMITH, NEW NOCTUID^ 97 smoky; secondaries more yellowish and powdery; all wings with an outer shade band and discal mark, less evident on primaries. Expands 1.15-1.35 in. = 29-34 mm. Habitat: Kaslo, B.C., July 27. Two males and five females; from Dr. James Fletcher, collected by Mr. J. W. Cockle, after whom the species is named. All the examples are in good condition and no two are alike. The two males are smaller than all the females, although the larger of the two is almost as large as the smallest female. So the males are also darker and less distinctly marked, the orna- mentation in one case, indeed, being scarcely traceable. In all the females all the markings are at least traceable, and in one case every feature is complete, and, in addition, the s.t. space is a little paler than the rest of the wing. The t}'pe of maculation is similar to insulsa, but there is no darkening of the cell and the wings are also too powdery. There are no strong positive characters, and in Hampson's Tables it falls between submolesta and pro- rellaris, neither of them American species. Euxoa criddlei nov. sp. Head, thorax and primaries mahogany-brown; the head and thorax darker, without markings; primaries with all the transverse maculation lost, except the s.t. line, which is traceable by a line of pale scales edging the darker, more blackish ter- minal space. No trace of claviform. Orbicular faintly indicated by a blackish powdering. Reniform faintly outlined by scattered pale scales interiorly filled with blackish. Secondaries dull yellowish becoming smoky at outer margin, with a dark discal lunule. Beneath, smoky, powdery; primaries darker; all wings with a dis- cal lunule. Abdomen dull smoky. Expands 1.40-1.50 in. = 35-37 mm. Habitat: Aweme, Manitoba, Aug. 24, 25, Sept. 4. One male and two females, in good condition ; from Dr. James Fletcher, collected by Mr. Criddle, after whom the species is named. This is a very simply marked form, and in fact, at first sight there appear to be no markings at all, so feebly are they indicated. In wing form the species is like pastora- lis, with which it will be most naturally associated in the list. In Hampson's Tables the species would fall in next to stigmatilis Sm., to which the new species has but a slight resemblance. Euxoa quinta nov. sp. Head, thorax and primaries dull ashen gray, the entire surface with uniformly placed brown irrorations, which are quite conspicuous under the glass, and give a soft shading to the insect. Transverse maculation, except s.t. line, brown or black- 98 ANNALS NEW YORK ACADEMY OF SCIENCES ish, broken, more or less lost. S.t. line pale, rather conspicuously relieved by a smoky preceding shade. Basal line marked by a geminate spot on costa and some- times by a dot on median vein. T.a. line geminate, outer line best marked, evenly oblique, with small outcurves in the interspaces; always broken. T.p. line gemi- nate, only a little bent over the reniform, parallel to outer margin; outer line a series of venular points; inner tending to becomie diffuse. A broad, diffuse, obscure median smoky shade. S.t. line irregular, complete or nearly so, emphasized by white scales. A series of small black terminal dots and a narrow line at base of fringes. Orbicular moderate, round or oval, incompletely marked by whitish scales. Reniform moderate, kidney-shaped, outlined by a vague yellowish ring, inferiorly black-filled. Secondaries smoky fuscous, more yellowish at base, with a dark discal lunula and pale fringes. Abdomen pale ashen gray. Beneath, primaries smoky with a powdery pale-gray border, an extra-median line marked on costa, and an obscure discal spot; secondaries pale gray, powdery, with a conspicuous black dis- cal line and an incomplete extra-median band, beyond which the marginal area is blackish. Expands 1.35-1.42 in. = 34-36 mm. Habitat: High River, Alberta (Mr. Thomas Baird); Kaslo, B.C., June 1, 30, July 7, 10 (Mr. J. W. Cockle). Three males and two females, all in good condition; received from Dr. James Fletcher. The examples are all very much alike, a slight difference in the amount of dark filling in the reniform and in the completeness of the transverse lines being all the variation noted. The species belongs with the hostoniensis series, but differs from all those previously known to me, in the dark secondaries of both sexes. It recalls scandens at first sight, but is much darker than that species throughout. Euxoa capota nov. sp. Head dark brown in front, vertex reddish gray, a black line dividing the two. Collar reddish at base, tip velvety black; a white line between the two. Disk of thorax reddish gray. Primaries brown ; median space very dark purplish brown, almost black; costal region to t.p. line whitish; the ordinary spots of the brown ground-color. A black basal shade margins the costal pale area inferiorly. T.a. line geminate, black, obsolete on costa, very distinct below it and with an inward curve at the middle of its course. T.p. line geminate, black, the outer line less distinct, almost straight from the costa to end of cell and then with a very small incurve. S.t. line pale, only a little irregular, chiefly defined by the slightly darker terminal area against the s.t. space, which is the lightest part of the wing. Clavi- form narrowly outlined in black, incomplete, concolorous. Space between the ordinary spots black-filled. Orbicular, U-shaped, open to the costal pale area. Reniform large, incompletely outlined by dark and pale scales, lunate rather than kidney-shaped. Secondaries smoky brown, with a small, darker discal hmule. Beneath, reddish gray, powdeiy, with a common outer line and a discal lunule on all wings. Expands 1.15-1.30 in. = 29-32 mm. SMITH, NEW NOCTUID^ 99 Habitat: Palmerly, Cochise County, Arizona, July and August. Eight examples, mostly in good condition, all very much alike and all females. The reference to Euxoa is in the sense in which that genus is used by Hampson. The frontal structure in this species is as in Chorizagrotis, but the body is not depressed. As there are no males, the antennal struc- ture of that sex cannot be used as a guide, and the generic reference must be provisional. The species is altogether unlike any other form known to me from our fauna, and the peculiar course of the median lines should serve as a means of recognition. Ufeus electra nov. sp. Ground-color dull chocolate-brown. Head and thorax with dark hair inter- mingled. Primaries so densely set with long black hair as to give the whole a blackish appearance. A black basal streak in the sub-median interspace extends almost to the middle of the wing. Another streak extends, with little interruption, through the cell and beyond it to the outer margin. T.a. line lost. T.p. line outwardly bent from costa, obscure, blackish, with small outward extensions on the veins. A series of black inter-spatial marks at base of fringes, becoming longer toward the apex. Secondaries dull yellowish, smoky, with an overlay of black hair; a distinct discal lunule and a well-marked extra-median shade line. Beneath, reddish gray, powdery, darker at the margins on primaries; secondaries with an obvious extra-median line and a distinct discal lunule. Expands 1.55-1.65 in. = 39-41 mm. Habitat: Oregon. Two female examples, without date or name of sender. Evidently they are electric-light captures, and more or less defective ; but their differ- ence from the allied forms is obvious. The species is nearest to plicatus in type of maculation, and it is quite probable that in some specimens, traces of the discal spots will occur. TJfeus hulstii nov. sp. Ground-color rather hght red-brown. Head and thorax without markings. Primaries with fine black hair, the veins a little darker. T.a. line distinct, single, blackish, outwardly oblique, with three distinct outward angulations, — one on the sub-costa, one below the median and the other on vein 1. T.p. line single, black, followed by a slightly paler shade, evenly and moderately outcurved, with short outward spurs on the veins. A series of small black terminal dots. Fringes cut with yellowish. Secondaries silky gray with a reddish tinge. Beneath, very pale pinkish gray, immaculate. Expands 1.38-1.42 in. = 34-35 mm. Habitat: Black Hills, Wyo. ; Stockton, Utah, July 22. Two male examples. One of them is from the Hulst Collection, with- 100 ANNALS NEW YORK ACADEMY OF SCIENCES out abdomen, but else in good condition; the other is from Mr. Thomas Spalding and in good shape. This differs from the other described species, all of which are represented in my collection by the distinct and rather even red-brown, and the well-marked median lines. It is perhaps nearest to satyricus in type of maculation, but differs obviously in color, in the absence of all trace of ordinary spots, and in the immaculate under side. Mamestra leomegra nov. sp. Ground-color blue-gray shaded with smoky, powdered and ornamented with black. Head with a black line across front. Collar with a black line across middle, dividing the smoky lower from the ashen upper portion. Thorax mottled with blue-gray, smoky, white and black, forming no distinct markings. Primaries with all the maculation obvious, but so obscured and mottled that scarcely any of it is clear-cut and distinct; the narrow yellowish s.t. line with the prominent black preceding shades forming the most conspicuous feature of the wing. Basal line geminate, black, broken, the whitish included space broad and most obvious; a pair of curved black marks just below the median vein. T.a. line geminate, black- ish, oblique, outcurved in the interspaces; included space broad, pale. T.p. line geminate, lunulate, a little irregular, broadly exserted over the cell and a little incurved below; included space narrower and not so pale as in t.a. line. There is an obscure, diffuse, smoky median shade, which darkens the outer part of the median space. S.t. line forms a small W on veins 3 and 4, where the preceding black shad- ing is less conspicuous than it is above and below. A series of conspicuous black terminal lunules. Claviform small, concolorous, black-margined. Orbicular, of good size, broadly and irregularly ovate, oblique, black-margined, a little lighter than the ground, with a smoky center. Reniform large, lunate, black-edged, out- wardly with a margin of white scales wthin the black, center smoky, inclosing a curved gray streak. Secondaries blackish, the outer margin narrowly gray. Be- neath, gray, powdery; both wings with a conspicuous black discal mark and a more or less evident extra-median line. The primaries have a narrow whitish outer border, and in the female this is obvious on the secondaries as well. Expands 1.90-2.00 in. = 47-50 mm. Habitat: Grand Lake, N.F., Aug. 28. Three males and one female, of which only one female is in really good condition. The specimens were caught at light by Mr. Owen Bryant, packed dry in cotton, and sent me through Mr. C. W. Johnson of the Boston Society of Natural History. The species is obviously related to imbrifera, but is larger and darker throughout, and distinctly more blue-gray in color. The W of the s.t. line, while small, is distinct. The antennpe of the male have the joints only a little marked, with little tufts of fine bristles and longer single cilise. The tuftings appear to be as in imbrifera, but less developed. SMITH, NEW NOCTUIDjE 101 Mamestra pallicauda nov. sp. Head and thorax dark brown; abdomen gray, the dorsal tuft at base brown. Primaries red-brown tending to gray, with black powderings and transverse lines. Basal line geminate, black, distinct; included space with pale scales; outcurved in the interspaces, reaching to the sub-median vein. T.a. line geminate, black, inner portion tending to become lost; outcurved in the interspaces, a little out- curved as a whole; below vein 1 the included space is white. T.p. line single, black, irregular, incurved in the interspaces, scarcely clears the reniform; a white lunule follows that part below the sub-median vein. The median space is very narrow; and the median shade, which is blackish, runs close to the inner border of the reni- form across cell, and then close to the t.p. line below it. S.t. line irregular, marked partly by blackish shadings and spots, and partly by the darker terminal space. A black terminal line broken by whitish points on the veins, the veins themselves more or less black-marked. Three white points in costa between t.p. and s.t. lines. Orbicular obscure, traceable as an indefinite paler brown blotch. Reniform small, oblique, incompletely outlined, a series of three white dots along the outer edge and a fourth at the lower inner angle. Secondaries smoky, the veins darker, fringes tipped with white. Beneath, smoky gray, powdery, with a smoky extra-median shade and a small dark discal lunule. Tip of abdomen of female obtuse, with a mass of white fluffy hair arranged so as to form a compact mass. Expands 1.24 in. — 31 mm. Habitat: Palmerly, Cochise County, Arizona, July; Huachuca Moun- tains, Arizona, July 12. Two female examples, one of them, belonging to the Brooklyn Institute, in perfect condition; the other, from my own collection, somewhat rubbed. This is altogether unlike any other species known to me, and eventually must be removed from Mamestra, to v/hich I have referred it tentatively in the absence of a male. It belongs to Hadena as limited by Hampson, and has only a basal tuft on the dorsum of the abdomen; but it agrees with none of the species that he places in that genus. The cylindrical, squarely trun- cate abdomen, with its dense tuft of white fluffy hair, is characteristic, and may indicate some unusual character in the male as well. Miodera nov. gen. Eyes moderate in size, round, hairy. Front protuberant, roughened, obtuse, without processes or plates. Tongue fully developed. Palpi small, oblique, not reaching to the middle of the front, .\ntennse of male lengthily bipectinated, the branches decreasing in length toward the tip, the last few joints merely serrate. Thorax quadrate, heavily clothed with scaly vestiture, forming an obscure anterior and somewhat more obvious posterior tuft; patagia well marked. Vestiture of under side dense, somewhat hairy, loose. Legs short and not especially stout, though the heavy vestiture makes them appear so; anterior tibiae and tarsi without 102 ANNALS NEW YORK ACADEMY OF SCIENCES special armature; the terminal claws, however, unusually long. Abdomen with a loose tuft at base, otherwise dorsum untufted. Primaries short, broad, trigonate, the apices well marked. Differs from Mamestra chiefly in the very stout body, lengthily pectinated antennae and protuberant roughened front. I cannot identify it with any of the genera of Hampson's monographic work. Miodera stigmata nov. sp. Head, thorax and primaries deep dark brown. Head with a scant admixture of gray and black scales. Collar with a blackish transverse line. Thoracic disk with an admixture of gray scales, varying in the examples; patagia with a black sub-margin. Primaries with smoky and blackish shadings variably mixed with gray, and with a sprinkling of yellow scales that gives a richness of color to the wings. Basal line black, geminate, interrupted on the sub-costa. A short black basal dash that just reaches the t.a. line. T.a. Une geminate, black, the included space some- times lightened by yellow scales, in course outwardly oblique, with three moderate outcurves. T.p. line geminate, black, abruptly bent out below costa, then almost parallel with outer margin; the inner line lunulate and usually, at least, traceable across the wing, the outer more even and usually lost below the cell. S.t. line more or less yellow, variably defined by darker preceding or foUowng shadings, with a well-defined W on veins 3 and 4. A lunate black terminal line followed by yellow venular points at the base of the long interlined fringes. Claviform a small but con- spicuous black loop. Orbicular round or nearly so, moderate in size, concolorous, ringed with yellow scales. Reniform large, upright, a little constricted at middle and expanded below, inferiorly black-filled, the upper half paler, and edged with yellow scales. Between the spots the cell is darker or even blackish. Secondaries smoky yellowish, with a discal lunule, a somewhat waved extra-median line and a distinct blackish terminal line. Beneath, gray, powdery, -s^ith a narrow, distinct extra-median black shade line crossing both -nings. All wings with a discal spot and a lunate marginal line. Abdomen like secondaries in color. Expands 1.04-1.14 in. = 26-28 mm. Habitat: Witch Creek, Cal., Jan. 12-Feb. 3. Ten males, in good or fair condition. This is a well-marked and rather pretty species somewhat resembling Mamestra ectypa, and it does not appear to vary to any considerable extent. Tseniocampa macona nov. sp. Ground-color of head, thorax and primaries, creamy to luteous gray. Head and thorax without maculation. Primaries more or less powdered with black atoms, and veins tend to become pale. Basal line geminate, broken, usually marked by black spots on costa and median vein. T.a. line outwardly oblique, even, of the ground-color or paler, marked on both sides by black scales so as to define the entire line in the best case, but so irregularly in others that it may become entirely lost SMITH, NEW NOCTUID^ 103 beyond the costal area. T.p. line concolorous or a little paler, almost parallel with outer margin, preceded by black scales or lunules, so variable that the line may be either completely defined, or almost lost. A black median shade extends obliquely from costa across the reniform, forms an angle at its lower margin, and extends obUquely inward to the middle of the inner margin. This shade is usually distinct, and when it is obscure the median lines are best defined. S.t. line concolorous or a little paler, a little irregular, defined by a preceding black powdering, which may extend across the wing or may be confined to the costal region. A series of black terminal dots in the interspaces. Orbicular concolorous, usually lost, sometimes defined by a slightly paler ring, then large, ovate, joining the reniform inferiorly. Reniform large, oblique, broadly oval, pale-ringed, always darker and usually con- trasting, filled with black powdering. Secondaries whitish with a reddish tinge, a small dark discal spot, a punctiform, obscure extra-median line, and a series of dark terminal lunules. Beneath, with a reddish tinge, coarsely black powdered; primaries with blackish orbicular and reniform and a broken exterior line; secondaries with dark discal spot and punctiform extra-median line. Expands 1.36-1.50 in. = 34-37 mm. Habitat: Witch Creek, Cal., Jan. 30, Feb. 1-14. TSvo males and two females, var}ung greatly, as indicated in the descrip- tion. At first sight the species suggests flaviannula; but the male antennas are not pectinated. They are bristle-tufted, and therefore the species belongs with alia. Sir George Hampson refers these species to Monima Hbn. Tseniocampa bostura nov. sp. Head, thorax and primaries dull luteous brown with smoky powderings, which give the insect a sordid appearance. Primaries with all the markings present, but not relieved or distinct. Basal fine geminate, blackish, complete, included space of the ground-color. T.a. line geminate, outwardly obhque, with small outcurves in the interspaces, outer portion well marked, included space of the ground-color. T.p. line with a moderate outcurve over cell and an almost even incurve below it, the inner portion obscurely lanulate, the outer punctiform. A very obscure median shade through the outer portion of the median space. S.t. line yellowish, narrow, only a little irregular, preceded by a continuous blackish shade, which darkens the outer half of the s.t. space. A continuous, slightly waved yellow line at the base of the fringes. Orbicular not traceable in the specimen. Reniform large, oblique, a little constricted, blackish-filled, obscurely outlined by yellowish scales. Secondaries dull whitish at base darkening to a smoky outer margin, the fringes more yellowish. Beneath, reddish gray, powdery. All wings with a distinct extra-median line and a small discal spot. Expands 1.30 in. = 32 mm. Habitat: Kaslo, B.C. One male, in good condition; from Dr. James Fletcher. The species is allied to rufula and indra, but is more sordid and powdery in appearance than either, while the course of the lines is quite different. The thoracic 104 ANNALS NEW YORK ACADEMY OF SCIENCES vestiture is thicker and the patagia are much better defined than in the alHed forms. It is Dr. Fletcher's No. 168. Taeniocampa fringata nov. sp. Rusty red-brown darkening to brown-gray. Lower part of front and palpi crimson. Antennae bright red with a white dot at base. Collar and thorax tending to become hoary through gray-tipped hair. Primaries tending to an overlay or powdering of bluish-gray scales, and with a vague irrorate appearance, the macula- tion never conspicuous and sometimes scarcely traceable. Basal line geminate, gray-filled, rarely evident. T. a. line geminate, a little darker than the ground, some- times with gray filling, a very little oblique, and slightly outcurved in the interspaces. S.t. line brown, geminate, evenly outcurved over the cell and a little incurved belov.-; included space concolorous; followed on each vein by a short blackish line which is interrupted by a pale dot, so that there is the appearance of a double dotted line, which is easily mistaken for the t.p. line. S.t. line pale, obscure, a little irregular, defined by a slightly darker preceding narrow shade line. A vague median shade line is traceable below the reniform, parallel to the t.p. line. Claviform barely trace- able in one example. Orbicular dusky, oblique, elliptical, with narrow yellowish outline, obvious in most specimens. Pteniform large, upright, a little constricted, dusky, narrowly ringed with yellow, obvious in all specimens. Secondaries smoky fuscous with carmine fringes. Beneath, gray with a crimson tinge, powcery. Both wings with a discal spot and outer hne, which are best marked on secondaries, but always at least traceable on primaries. The tarsi tend to become narrowly white- ringed. Expands 1.24-1.34 in. = 31-33 mm. Habitat: Monterey County, Cahfornia, March; Santa Cruz Mountains, CaHfornia. Five males and two females, all save one in good condition. This is an ally of prceses and saleppa, and yet more closely of transparens. It is refer- able to the Perigrapha of Hampson, and has the ridged crest of the species that stand as Stretchia in our Catalogue. Except in the ground-color, there is very little variation among the specimens at hand. Stretchia erythrolita Grt. Until recently this species has been represented in my collection by a single male example labeled by Mr. Grote, and agreeing well with his description and type. In 1906 I received two examples from Pasadena, taken in March and April, which indicated quite a range of variation, but wiiich nevertheless were very similar to the typical form. Recently I re- ceived from San Diego County a series of upwards of thirty examples, taken in early February, no two of which were alike, the extremes being so far apart that probably I should have considered them distinct, had I received SMITH, NEW NOCTUIDM 105 single specimens only of each. In color they vary all the way from uniform mouse-gray to uniform smoky black, with scarcely a trace of maculation. The s.t. line is most frequently present and the tendency is to a pale terminal space, the extreme of this type being a glossy black primary with a contrast- ing gray terminal space. Then the black breaks up at base and the wing becomes mottled in every possible intermediate form. In the pale examples, the reniform tends to become relieved, especially in the males, and in the extremes this is ringed with yellow, and filled with dark brown. The orbic- ular is rarely present, but may be as conspicuous as the reniform, though in only one case is it as well defined. I have no information as to the habits of the insect ; but it is quite obvious that it may at times be much more common than the number of specimens in collections indicates. Himella rectiflava nov. sp. Of the usual powdery luteous ground-color, the markings obscure, except for the conspicuous yellow s.t. line and the scarcely less defined dusky median shade line. Head and thorax with scattered black powderings only. Primaries, basal line tracei^ble by the pale included shade and the slightly more dense powderings at its borders. T.a. line geminate, smoky, included space not paler, with a very regular and even outcurve from costa to inner margin. T.p. line geminate, tending to become punctiform, the veins blackish beyond the line and so interrupted as to give the appearance of geminate dark points; outwardly bent over cell, with the angle on vein 7, below which the line runs evenly oblique to the inner margin. Me- dian shade distinct, blackish, a little diffuse, outwardly bent from costa to bottom of reniform, then evenly oblique to the inner margin. S.t. line conspicuous, yellowish, preceded by a distinct, even, continuous, narrow brown shade, the following terminal space darker than the rest of wing. A yellowish crenulated terminal line, from the points of which pale lines extend across the fringes. No obvious claviform. Orbicular round, with narrow smoky ring, of ground-color, but not powdery. Reni- form upright, oblong with rounded corners, concolorous, defined by a narrow dusky line within which there is a paler ring. Secondaries fuscous, paler at base, fringes more luteous. Beneath, reddish gray, powdery. Both wings with an extra-median line; secondaries also with a discal spot. Expands 1.10 in. = 27 mm. Habitat: Huachuca Mountains, Arizona, July 30. One male specimen, in good condition as to wings, somewhat defective as to antennae, etc. The specimen was received in paper in a purchased lot, and the collector is unknown. It belongs to Eriopyga of the Hampson Catalogue, in the series in which the males have ciliated antennae and no other conspicuous secondary sexual characters. 106 ANNALS NEW YORK ACADEMY OF SCIENCES Orthodes keela nov. sp. Head, thorax and primaries red-brown; head with a paler, more yellowish shad- ing. Secondaries and abdomen smoky. Primaries with all the normal markings traceable, but none of them distinct or well written. Basal line geminate, smoky, obscm^e, included space with a few yellowish scales. T.a. line geminate, smoky, obliquely outcurved, with small outcurves in the interspaces, some pale scales in the included space over the costal region, the line tending to become obscure below the middle. T.p. line geminate, blackish, only a httle bent over cell, then almost evenly parallel with outer margin; inner portion more or less lunulate; outer, punctiform below costal region. An outwardly curved smoky median shade. S.t. line marked by scattered yellow scales and by a continuous, narrow, blackish preceding shade, only a little irregular in course. A broken, yellowish terminal line. Orbicular small, obscurely outlined by yellowish scattered scales. Reniform small, narrow, oblique, a little constricted, outlined and partly filled by yellow scales, with a black- ish superior dot and a dark inferior filling. Secondaries uniformly smoky with a bronze luster, the fringes more yellowish. Beneath, primaries with disk smoky, lustrous, the margins yellowish with reddish powderings; secondaries yellowish with reddish powderings, with a smoky broken outer band and a smoky discal lunule. Expands 1.07-1.15 in. = 27-29 mm. Habitat: Palmerly, Cochise County, Arizona, August. One male and one female, in good condition; from the collection of the Brooklyn Institute of Arts and Sciences. The male is the smaller of the two, more deeply colored and less distinctly marked. The species is an ally of vecors, and ranges next to it in Hampson's Catalogue, under Eriopyga. It is narrower winged, however, much more uniformly tinted, with more even median lines and a different s.t. line. In wing-form it is nearer to imora Strck., which is darker lustrous, and has the maculation reduced to a small gray reniform. Faronta nov. gen. Eyes haiiy, large, round, globose, not overhung by long cilia. Tongue fully- developed. Front roughened, slightly protuberant, without processes or excisions. Palpi straight; temiinal joint very short, poorly developed, not projecting much beyond front; the second joint with short vestiture. Antennae in male, ciliated; in female, simple. Thorax convex, rounded; vestiture hairy, forming no tufts, rather smoothly laid. Legs moderate in length, strong, without spines or other unusual annature on tibiae or tarsi; tibise in the male more thickly clothed with hair, but forming no obvious tufts. Abdomen smoothly clothed, without tufts or fringes of any kind, stout, extending well beyond the hind angle of secondaries. Primaries elongate, narrow, sub-lanceolate, the apex not acutely drawn out, margin gently rounded, venation normal. Secondaries proportionate. Differs from Leucania in the stout convex thorax and long stout abdomen, as well as the narrow elongate wings. From Neleucania it differs in the SMITH, NEW NOCTUID^ 107 more robust build throughout, in the more closely appressed vestiture and the rounded margin and apex of primaries. From Meliana it differs in the stouter form, less pointed wings, and comparatively simple antennae of the male. The roughened front may not be peculiar, in the absence of plates or processes. Faronta aleada nov. sp. Head, thorax and abdomen uniform creamy white or grayish tending to yellow- ish, the head usually most intense in color. Primaries with the disk a faint leaden gray, costa and internal margin creamy white, median vein pale, and dividing into pale rays on veins 3 and 4. In the apical region the veins are a little dark marked. No lines or dark spots on the wing. Secondaries white in both sexes. Beneath, white; primaries with a tinge of yellow, which is better marked at the margins. Expands 1.30-1.42 in. ^ 32-35 mm. Habitat: Brazos, Tex. One male and three females, all in good condition; from tlie collection of the Brooklyn Institute of Arts and Sciences. The species is entirely unlike any other of our leucaniids, and agrees with nothing described by Hampson from the adjoining faunal region. The tendency is for the leaden gray disk to become rubbed so as to give a uniform creamy appearance. Anarta Ochs. The species of this genus are not well represented usually in American collections, and my own material has been for two years or more eked out by a collection loaned me by Mr. Philip Laurent of Philadelphia. This was mostly purchased from Staudinger, and contained a fair series of the circum-polar species, including those listed as common to the American and European faunas. Sir George Hampson's revision of the species drops out several of our listed names, and adds others, so that I found it desirable to rearrange my material, and did so v.ith very interesting results. Three series are recognized : — I. Antennae of male strongly serrate and fasciculate; fore wings very narrow. II. Antennae of male minutely serrate and fasciculate. III. Antennae of male ciliated. The first of these series contains only a single species, and is not repre- sented in our fauna. The series in which the male antennae are minutely serrate and fascicu- late, or bristle-tufted, is divided as follows: — 108 ANNALS NEW YORK ACADEMY OF SCIENCES Hind wings white. Primaries with s.t. hne angled inward in discal fold . . staudingeri Primaries with s.t. line not so angled. Primaries with prominent series of dentate black marks before s.t. line richardsoni Primaries without such marks before s. t. line . . quadrilunata Hind wings yellowish leucocycla Hind wings uniformly suffused with fuscous. Primaries with the stigmata not filled with blue-gray . etacta Primaries with the stigmata filled with blue-gray . . membrosa Staudingeri has not appeared heretofore in our Catalogue; but I found, on comparing the figure and descriptions carefully, that I had two males, one from Labrador and one from "British Columbia," which were apparently the same, and which agreed with the characters given for the species. Of quadrilunata I have a pair from Colorado, which are properly de- termined. An example from Laggan may indicate a new form. Of richardsonii I supposed I had a long series; but I found, to my sur- prise, that only one nice pair from Labrador answered all the requirements of Hampson's definition. My Greenland examples received through Staudinger did not answer at all. The White IMountain examples, which stand under richardsoni in our collections, had the s.t. line of staudingeri; and the long suite of specimens from Newfoundland represented yet another form. They are distinctly yellow-winged, but will not do for leucocycla at all. The species marked schoenherri in my collection, and to which name leucocycla has been cited heretofore as a synonym, vras neither one nor the other. Using the same characters used by Hampson, in a somewhat different form, I differentiate the species now before me as follows : — S.t. line of primaries angulate and dentate. Secondaries white or nearly so. Ordinary spots of primaries white-marked, median line white-shaded staudingeri No white on primaries, all the pale markings bluish gray hampa Secondaries decidedly yellow. Ground-color blue-gray, terminal space contrastingly blue-gray flanda S.t. line of primaries even, or scarcely irregular. Secondaries Avhite, primaries contrastingly black and white marked. SMITH, NEW NOCTUID^ 109 T.a. line oblique, outcurved in the interspaces . . . richardsoni T.a. line angulated on the median vein, then rigidly oblique to inner margin lanuginosa Secondaries pale yellowish, primaries smoky brown, not contrasting. S.t. line distinct, with preceding dusky shades or spots squara S.t. line partly obliterate, preceding shades on costa only quadrilunata Etacta and memhrosa are left out of consideration here. Hampa and jlanda are allies of staudingeri, but are larger and darker. Flanda has decidedly yellow secondaries, and that is its chief superficial difference from hampa. I might have deemed it racial or varietal, were it not accompanied by a decided difference in the eyes; those of flanda being distinctly larger, and decidedly more rounded. Squara is based on Greenland examples of schosnherri, from which it differs by the distinctly yellowish secondaries and the totally different type of transverse lines. I am, of course, assuming that all the names cited by Hampson to richardsoni are really identical with the form to which he has applied that name. The third series, in which the male autennse are ciliated only, is separated by Hampson as follows: — Hind wings bright yellow. Fore wings with the ground-color deep red .... myrtilli Fore wings with the ground-color blackish. Fore wings with the reniform white-filled .... cordigera Fore wings with reniform not white-filled .... mimuli Hind wings yellowish, tinged with brown impingejis Hind wings uniform brown phma Hind wings white, more or less suffused above with fuscous. Fore wings broad, triangular. Reniform without whitish annuli ' melanopa Reniform wuth whitish annuli mimula Fore wings narrow, elongate. Fore wings pale olive-gray mausi Fore wings fuscous zemhlica Myrtilli Linn, is in our collections as acadiensis Beth., and is listed from Canada northward. It occurs also in the mountains of Colorado, and I have never been sure that there was only a single species represented. I have compared the Colorado examples recently with German specimens. 110 ANNALS NEW YORK ACADEMY OF SCIENCES and am by no means certain that the two are identical. The resemblance is very close, however, and my material is not sufficient to induce me to dispute the union. Cordigera Thumb, is a very sharply-marked species, and I have in my collection examples from Colorado, Labrador and Germany, which are practically alike. Mimuli Behr. is a Californian species unknown to Hampson, and not represented in my collection. The type has been destroyed in the San Francisco fire. Impingens Wlk. — with curta Morr., nivaria Grt. and perpura Morr. as synonyms — is a purely American species, which differs quite markedly from the preceding species in general habitus, and comes nearer to Scoto- gramma in wing-form. I have it from Colorado onl}^; but it is also recorded from British Columbia. Phcea Hampson is a new species to our fauna, and quite a close ally, in appearance, to the preceding. It comes from Victoria Land, Cambridge Bay, and is not represented in my collection. Melanopa Thunb., re-described by Packard as nigrolunata, is another sharply-defined form which is very widely distributed. It occurs in the United States from -Mount Washington northward, and extends along the Rocky Mountain chains into New Mexico. My examples are from Col- orado and Labrador, without very much difference between them. Miviula Grt. is from New Mexico, and the type is in the Snow Collection. Professor Snow was good enough to send it to me for examination nearly fifteen years ago, and since that time I have not seen another example, so far as I know. Laerta Smith was not known to Hampson when he wrote, and differs from melanopa in the more sordid fuscous color throughout and by the much reduced whitish area of secondaries. From mimula it differs in the ordinary spots, the rcniform not being ringed with pale scales. This really resembles A. kelloggi Hy. Edw. very much; but Hampson places that species in Sympistes with naked, reniform eyes, while in laerta they are distinctly hairy. Mausi Hampson is from E. Turkestan, and the only species in the series that is not American or circum-polar. Zemblica Hampson is from Nova Zembla, and is a narrow-winged ally of mausi. While not really American, it is not unlikely that the species will be found in Alaska, and so should be looked for. The other species referred to this genus I have commented upon in the N.Y. Ent. Soc. Jour., 1907, Vol. XV, p. 151, and have there stated the disposition made of them. I still have in my collection a few examples that do not fit into any of the SMITH, NEW NOCTUID^ 111 described species ; but they are not sufficiently well marked, nor in sufficient number, to warrant me in describing them at present. Anarta hampa nov. sp. Ground-color dull smoky fuscous with black and gray maculation. Patagia ■with sub-marginal black line and gray disk, dorsum posteriorly mottled with gray. Basal line black, outwardly shaded with gray, with two moderate angulations. T.a. line black preceded by a gray shading, a little oblique outwardly, irregularly out- curved. T.p. line denticulate, black followed by a narrow gray shading, moderately outcurved and only a little incurved in its course. S.t. Une gray or yellowish, marked by the evenly dark s.t. space, drawn in on veins 2 and 5, outcurved between and on each side. A series of black terminal lunules. The fringes dusky, cut with yellowish. A vague median shade in the paler examples. Claviform small, but distinctly outlined. Orbicular small, round or oval, more or less gray-marked. Reniform small, narrow, upright, with narrow pale ring, a little constricted centrally. Secondaries very pale straw-color, almost white, smoky at base and along inner margin, with a distinct discal mark, a narrow, almost crenulated outer line, and a broad blackish outer margin; fringes white. Beneath, whitish, more or less shaded with blackish, with a black discal spot, an extra-median blackish line, and a blackish outer margin on all wings. Primaries with fringes checkered, black and white; secondaries with fringes white. Expands 1.10-1.20 in. = 28-30 mm. Habitat: White Mountains, New Hampshire. Two males and one female, all in good condition. One of the males came originally from Mrs. Slosson; the others have no indication of their source, and none have a date label. Mossy yellow scales are in the median space in cell and sub-median interspace, and along the line of the s.t. line, beyond it. Anarta flanda nov. sp. Head and thorax gray to blackish, mixed with black scales; collar gray-tipped; patagia with black sub-marginal line, disk posteriorly black-spotted. Abdomen smoky, with a yellowish tinge in the male. Primaries gray marked with black, and sometimes so much black-powdered that only the lines and terminal space are of the gray base. Basal line geminate, black, included space gray, with two distinct out- ward angulations in its short course. T.a. line geminate, black, included space gray, outwardly oblique and very irregular. T.p. line lunulate, black, denticulate on the veins, the accompanying gray shade narrow, moderately outcurved over the cell, and then almost parallel with outer margin. S.t. line irregularly and variably dentate, sharply defined by the contrast between the black or blackish s.t. space and the gray terminal area. A series of small black terminal lunules between which the long dark fringes are cut with yellowish. In lighter examples a distinct median shade line extends from costa outwardly between the ordinary spots, and then, from an obtuse angle, inwardly oblique to the inner margin. Orbicular round or oval, 112 ANNALS NEW YORK ACADEMY OF SCIENCES small or moderate in size, usually gray. Reniform, moderate, upright, centrally constricted, usuallj'- obscure, rarely paler in part. In the median space there is usually a more or less obvious powdering of mossy yellow scales at the outer portion of the cell and in the sub-median interspace. Secondaries dull yellow, smoky at base and along inner margin, in the female with a dark discal lunule, a narrow blackish extra-median line and a broad blackish outer border; fringes yellow; be- neath, yellow. Primaries paler, outer border blackish with a black discal spot. Secondaries with a black discal spot, an incomplete extra-median line and a narrow blackish border. Expands 1.00-1.16 in. = 25-29 mm. Habitat: Newfoundland (Mr. Owen Bryant). Over fifty exampk s, taken at light, and sent unpinned in layers of cotton. There are few antennae, and legs are at a premium; but many of the speci- mens are otherwise in good condition, and the series is excellent to determine the constancy of the type. They range from almost ash-gray with black transverse lines to almost black with gray lines, the terminal space being always contrasting, and relieving the irregular s.t. line. The secondaries tend to become suffused, and examples of both sexes are almost uniformly washed with black. The mossy yellowish shading is a decidedly variable quantity. Anarta squara nov. sp. Head, thorax and abdomen blackish, the vestiture of head and thorax more yellowish, somewhat intermixed with white. Primaries dull smoky brown, more or less gray, and black-powdered. Basal line distinct, single, black, rather diffuse. T.a. line black, single, diffuse, almost upright to vein 1, and then outwardly bent to inner margin. The space between basal and t.a. line may be gray-powdered. T.p. line more or less lunulate, evenly outcurved over cell and scarcely drawn in below it, accompanied outwardly by paler lunules and a more or less traceable defining-line. S.t. line even, pale, preceded by blackish or dark spots or shadings. A series of black or dark terminal lunules. The dark fringes narrowly pale cut. Orbicular large, irregular, oblique, incomplete, concolorous, or paler. Reniform large, upright, centrally constricted, incomplete, more or less marked with pale. Secondaries dull yellowish, smoky along inner margin, with a broad blackish outer marginal band and a blackish discal lunule. Beneath, all wings whitish to a broad black marginal band, and all with a distinct black discal spot. Expands 1.30-1 .38 in. = 32-34 mm. Habitat: Greenland. Two males and one female. The female is more uniform in color, and has no white shadings. One male is much like this, but the median space is darker, the lines are better marked, and the paler shadings are more obvi- ous. The other male has the basal and terminal spaces and the ordinary spots mottled with gray in which mossy yellow scales are intermixed. A somewhat defective female from Colorado may be referable here. SMITH, NEW NOCTUIDJE 113 Luperina innota no v. sp. Ground-color a reddish rusty luteous. Head and thorax concolorous, somewhat deeper in reddish than primaries. Primaries with median space more reddish and darker than basal and extra-median areas. Basal line barely indicated on costa. T.a. line single, brown, barely relieved, outcurved in the sub-median interspace. T.p. line single, brown, barely relieved, with little outward points on the veins, evenly outcurved over the cell and almost evenly oblique below it. S.t. line marked near costa by a brown shade in the s.t. space, thence lost, or barely marked by a slightly darker preceding shade. Claviform long, narrow, extending nearly to t.p. line, but so slightly relieved in outline as to be readily overlooked. Orbicular round, moderate in size, a little paler, else not defined. Reniform moderate, broadly lunate, a little paler than its surroundings. Secondaries pale, transparent yellowish with a smoky tinge. Beneath, yellowish; secondaries paler, primaries tinged with smoky in the male. Expands 1.36-1.45 in. = 34-36 mm. Habitat: Yellowstone Park, Wyoming, July 8; Arangie, Idaho. One male and one female in good condition, and two poor males, which are probably the same; from Colorado localities. The type of maculation is not unlike that of passer; but the faded, rusty, washed-out appearance is more like the orthosiids of the citima type. A male example is in the British Museum, and I owe acknowledgments to Sir George F. Hampson for comparing it with the Museum material. Hadena (Luperina) birnata nov. sp. Head and thorax dark purplish brown, vertex of head and tip of coUar with yellowish hair admixed. Primaries light brown; the upper half to t.p. line, a quadrate patch in s.t. space on costa, and terminal space (save apex), dark brown with a blackish shade or powdering. Basal line obscurely marked as a pale spot on costa. T.a. line vaguely traceable by a paler shade across the dark portion of wing, altogether lost below that. T.p. line obvious throughout its course, but hardly well defined: on the costa it is obviously geminate, and makes a rather abrupt even bend over the cell, well defined by the difference between the dark median and pale s.t. space; below vein 2 the difference between the spaces is slight, and the line is defined by a narrow line of darker brown scales. S.t. line marked chiefly by the contrast between s.t. and terminal spaces, the darker shades extending inward opposite the cell and in the sub-median interspaces. A series of small black terminal lunules. Fringes cut with yellowish. Claviform absent, or barely marked by a few black scales. Orbicular obscure, vaguely black-edged, irregular, of moderate size. Reniform moderate in size, broadly lunate, discolored, lighter than the rest of the wing, not completely outlined nor well defined, inferiorly, and at the branching at the end of the median, marked with black scales. Secondaries even dull yellowish or smoky. Beneath, yellowish gray, powdeiy; disk of primaries darker; secondaries, costal area and a discal spot darker. Expands 1.12-1.32 in. = 28-33 mm. 114 ANNALS NEW YORK ACADEMY OF SCIENCES Habitat: Newfoundland. Three male examples, one of them almost perfect, a second fair, and a third more or less oily, yet with maculation in good condition. This is a close ally of L. passer Gn., and I thought, at first, a small, local race; but in the long series of passer in my collection, covering from the Atlantic to the Pacific, and the Rocky Mountain region into the mountains of Canada and Manitoba, there are certain features that occur always, in spite of differ- ences in size, and variations in color and markings. In the almost total absence of claviform, in the form, marking and outline of reniform, and in the course of the s.t. line, the new species differs most markedly from passer, as well as in the smaller size. A defective example from St. John, N.B., will probably prove referable here. It might be added that I have an example of true passer from Grand Lake, N.F., as small as hirnata, but quite characteristic in other respects. Xylophasia illustra nov. sp. Ground-color sooty black, dull. Head and thorax concolorous. Primaries with all except the s.t. line lost. The latter is marked by white scales, but is broken and fragmentary: so far as it shows, it is irregular, indicating a small W-mark, and partly preceded by velvety black scales forming an in-egular, vague preceding shade. A yellowish line at the base of the fringes, emphasized by larger dots at the ends of the veins. The reniform is vaguely indicated by paler scales. Abdomen dusty gray, the dorsal tuf tings well marked. Secondaries yellowish gray with a darker hne at the base of the paler fringes. Beneath, smoky gray; primaries darker with terminal space paler; secondaries paler, more powdery, with a moderate discal spot. Expands 1.52 in. = 28 mm. Habitat: High River, Alberta. A single good male, taken by Mr. Thomas Baird and sent me by Dr. Fletcher. The species resembles spuiatrix and plutonia in the dark color; but this color is dull, not glossy, and the secondaries have no trace of yellow or brown. Xylophasia miniota nov. sp. Ground-color dull, smoky fuscous without strong contrasts of any kind. Front of head and collar, inferiorly, more yellowish; front with a black transverse line; collar with a black line dividing the lower pale from the upper darker portion; disk of thorax mottled with black scales. Primaries dull with black powdering, all the maculation present, but not contrasting. A short black streak at base, reaching to the basal line, which is geminate, blackish, included space a little paler. T.a. line geminate, blackish, included space concolorous, outwardly oblique, with a little irregular outcurve. T.p. line geminate, the inner portion black, more or less lunu- late and irregular, the outer obscure, brown, even, partly lost : as a whole, some- SMITH, NEW NOCTUID^ 115 what irregularly outcurved over cell and decidedly incurved below it. S.t. line narrow whitish, irregular, with a distinct W, preceded by sagittate black marks and shades which tend to become lost, and sometimes outwardly emphasized by black scales. A series of black terminal lunules, beyond which the fringes are cut with, yellow. Claviform short; broad, outlined by blackish scales, concolorous. Orbicular of good size, irregularly oval, oblique, incompletely outlined, not so powdery, and sometimes a little paler. Reniform large, broad kidney-shaped, out- lined in black, outwardly relieved by a pale blotch which has somewhat the appearance of a small reniform stuck in the upper outer comer of a very large one. Secondaries pale dirty yellowish, outwardly smoky, with a more or less obvious outer line and discal spot, darker in the female. Beneath, smoky, powdery; sec- ondaries paler; all wings with a more or less well-marked extra-median line and a small dusky discal spot. Expands 1.36-1.62 in. = 34-41 mm. Habitat: Manitoba; Miniota, May 5, 11, 22; Cartwright, May 24. Three males and six females, mostly in fair condition, are under exami- nation, two of them belonging to Mr. Heath, the others received through H. H. Brehme. The species is in some respects intermediate between versuta and riinata, and is characterized principally by having no very strong characters. There is quite a variation in the distinctness of the sagittate marks preceding the s.t. line, one example from Cartwright having the entire series fully defined, while in other examples they are almost entirely absent. Hadena ferida nov. sp. Ground-color dull rusty brown with black powderings. Head with a dusky frontal line. Collar with two narrow blackish lines. Thoracic disk and patagia more or less marked with dark brown or black scales. Primaries with all the normal maculation present, but not constrasting, and more or less obscured by black powder- ings. Basal line geminate, black, broken, angulated. T.a. line geminate, black, the inner part less marked, outwardly oblique, somewhat curved, with an obtuse angle just below the middle. T.p. line geminate, inner portion somewhat lunulate, outer more even and less distinct, followed by a series of pale venular points; out- wardly bent over cell, then oblique, nearly parallel to the outer margin, except for an incurve in the sub-median interspace. S.t. line yellowish, broken, almost punc- tiform in some examples, a distinct though broken W on veins 3 and 4. A series of black terminal lunules, between which the fringes are cut with yellow. There is a somewhat obscure, diffuse median shade, which is more obvious on the costa and again below the claviform, where the entire median space is somewhat darkened. Claviform pointed, large, extending across the median space, the lower margin form- ing an obvious black bar, the upper margin less conspicuous and sometimes incom- plete. Orbicular very large, oblique, irregularly ovate, incompletely outlined by black scales, a little paler than ground, with a dusky central dot, spot or line. Reniform large, irregular, the upper and lower margins extending beyond the cell, and not defined, more or less marked with yellowish scales, and tending to central lines. Secondaries smoky, paler at base, with a dark terminal line at the base of 116 ANNALS NEW YORK ACADEMY OF SCIENCES the yellowish fringes. Beneath, gray to smoky, powdery, with a more or less marked extra-median line and discal spot on all wings. Expands 1.32-1.52 in. = 33-38 mm. Habitat: Newfoundland. Four female examples, in good to fair condition except for legs and antennae. The thoracic crests are well marked, the anterior divided cen- trally; abdominal tufts distinct, those on 3d and 4th segments even con- spicuous. The species has no very close allies in our lists, but is perhaps nearest to miniota, with which, nevertheless, it can hardly be closely com- pared. Eadena susquesa nov. sp. Head a dull rusty luteous. Collar luteous gray inferiorly, leaden or ash-gray at tip. Thorax with gray and black mottlings and lines over a rusty luteous base; the disk of patagia luteous. Primaries rather bright reddish luteous, with rusty brown markings and ash-gray shadings. Median Unes obscure. T.a. line traceable chiefly by the difference in shade between the luteous basal space and more gray- shaded median space, also by dusky venular marks which are not connected. T.p. line indicated on costa, lost over the cell, but traceable again below vein 4, and there parallel with outer margin. There is no obvious s.t. line. A series of inter-spatial blackish terminal lunules tend to unite into a shaded line below vein 4. A narrow yellow line at base of fringes, which are narrowly cut with yellow beyond the veins. There is a rusty brown streak at base below the median vein. Claviform large, con- colorous, outlined in rusty brown, extending almost across the median space: beyond it the interspace is yellowish to the outer margin. Orbicular round or nearly so, brown-ringed, then with a yellow annulus, gray-centered. Reniform large, upright, a little constricted, gray-filled, rather obscurely outlined in brown and yellow, a conspicuous yellowish shade beyond it toward apex. The veins tend to become blackish marked; and, beyond the t.p. line, veins 3 and 4 are whitish-bordered to the outer margin, gi^^ng them a white-rayed appearance. Secondaries dull smoky brown with a darker discal spot and a blackish line at base of the white-tipped fringes. Beneath, yellow-gray, more or less mottled and powdery, with variably distinct outer line and discal spot. Expands 1.20 in. = 30 mm. Habitat: Claremont, Cal. (Carl Baker); San Diego, Cal. (Frank Merrick). Two male examples, in good condition, neither with date of capture. The example from Mr. Baker has been in my collection a long time awaiting a mate; the example from Mr. Merrick is just received, and, while it is not exactly a mate, it is at lea.st a duplicate that shows the species to be a good one, and not discolored, as I had suspected. The peculiar reddish luteous ground, the gray shading, and the tendency to a strigate t\'pe of maculation, give the species a superficial resemblance to Morrisonia, and more especially to mucens; but it is really allied to Hadena fumosa, and has the excision below the apex of the secondaries well marked. SMITH, NEW NOCTUID^ 117 Orthosia dusca no v. sp. Has the general appearance of euroa, but is smaller, darker, with more diffuse maculation and with shorter, broader primaries. I have a series of ten eastern euroa ranging in locality from New York to Kittery Point, Me., and a series of over forty specimens from various points in Manitoba and British Columbia, and the latter are uniformly different in the points just mentioned. In the females the difference is much more marked, as a rule, than in the males; for in the female euroa the primaries are usually distinctly rectangular or even a little pointed at tip, the median shade is distinct and well defined, and all the maculation is neatly written: in dusca, on the other hand, the primaries are quite as stumpy in the female as in the male, the median shade is diffuse, often indistinct, and usually all the markings are obscure and mottled. Expands 1.-1.12 in. = 25-28 mm. Habitat: Cartwright, Miniota and Winnipeg, Manitoba, August and September; Kaslo, B.C. Cucullia phila no v. sp. Head, thorax and primaries bluish gray. Head with two obscure blackish transverse lines. Thorax A\ath disk brownish, the patagia obscurely sub-margined with brown or blackish. Primaries tending to brownish along the costal region, a distinct rusty shade in the cell where the ordinary spots are vaguely indicated. A distinct wliite, diffuse blotch in the sub-median interspace before the curved black mark representing the t.p. line. T.a. line traceable, single, slender, black, with long outward teeth, that in the sub- median interspace reaching almost to the middle of the wing. T.p. line vaguely indicated, except in the sub-median inter- space, where it forms a black incurve, and over vein 1, where it is bent outwardly and is accompanied by a white band. An obscure black basal streak into the s.m. tooth of t.a. line. An oblique black streak extends from the curve of the t.p. line to the margin just below vein 2. The veins are black-marked, and beyond them the brown fringes are cut with gray. There is a narrow, black, broken terminal line. Secondaries white to the middle, then darkening gradually to a deep smoky brown outer border, the fringes white. Beneath, primaries glossy smoky brown; secondaries as above, but the dusky outer border is narrower. Abdomen grayish white, the dorsal tuftings brown. Expands 1.50-1.60 in. = 37-40 mm. Habitat: Philadelphia, Pa.; Maryland. Tw^o males and two females. The two males and one female are from Mr. Frederick Weigand of Philadelphia, and are bred specimens. The Maryland example is old, and has been left unnamed for years, because I had no record of its source, and I doubted a new eastern species so rare that only one example should occur in collections. It is more sordid in appear- ance than the bred examples, and has a brownish shading throughout the primaries, which obscures the white blotch in the median space. 118 ANNALS NEW YORK ACADEMY OF SCIENCES The species is allied to speyeri, but is smaller and darker throughout, with comparatively broader primaries. The larva, an inflated specimen of which is sent by Mr. Weigand, has the head black, clypeal sutures and an inferior lateral spot yellow; a broad orange dorsal line bordered by a broad black band which cuts into and vertically divides a yellow lateral line; a broad orange sub-lateral line inferiorly edged by a broken black line. Feet yellow, black-ringed at base. Ventral surface yellow, marked with a broken black line toward the sides. The margins of the first thoracic segment are yellow above, and the posterior margin of the dorsal hump on segment 12 is also yellow. The larvae were taken in fall, "feeding on the perennial or New England Aster," in Fairmount Park. Adults emerged the spring following, date not quoted. Copicucullia mala nov. sp. Head, thorax and primaries whitish gray. Head with front mixed with brown- ish; collar with obscure brownish transverse Hnes. Thorax with brown scales inter- mingled, but no definite raaculation. Primaries with transverse maculation lost, and ordinary spots not traceable. T.a. line marked by an oblique costal brown streak. On the inner margin is a black streak, which extends from near base to about the middle of the wing. A narrow black line extends from base, through sub- median interspace, to middle, where it dilates, and forms a streak which is dislocated at half its course, and reaches the outer margin below vein 2. Veins blackish-marked; costal region a little darker; an obscure dusky shade extends inwardly from outer margin below apex toward the middle of inner margin; but it is interrupted before the sub-medial black streak, and practically lost in the ground-color. Secondaries smoky, a Uttle paler at base, the fringes white. Beneath, very pale whitish gray; the primaries a little darker. Expands 1.30 in. = 32 mm. Habitat: Witch Creek, Cal., Aug. 12. A single male, in fair condition. This resembles eulepis Grt., but is smaller. The t.p. line is completely lost, and there is no black marking below vein 4 on the outer margin. There are other, minor differences; but those named above are most obvious. Plagiomimicus dollii nov. sp. Ground-color a luteous yellow overlaid and shaded by pale chocolate-brown, the lines luteous golden brown, and a golden brown tinge also reflected from the primaries. Head and thorax uniform brown; abdomen paler, more yeUow-ish. Primaries with t.a., median and t.p. lines single, sub-paraUel, each with a strong outward acute angle. In the t.a. line this angle is near the middle; in the median line it is on vein 5, opposite the lower angle of the cell; in the t.p. line it is above vein 6; and at the point of angulation an oblique dusky shade continues to the apex SMITH, NEW NOCTUIDM 119 seeming at first a continuation of the line. The s.t. Une is marked by this obhque shade near costa, but below only by the difference between the luteous terminal area (which is the palest portion of the wing) and the slightly darker, very narrow s.t. space. A golden brown, continuous, even, terminal line at the base of the yellow- ish Drown fringes. The ordinary spots are large, concolorous. Orbicular round or nearly so, inconspicuously ringed with darker brown. Reniform broad, a little constricted, incompletely defined in brown. Secondaries yellow with a golden luster, smoky toward base within a dusky extra-median line. A faint dusky lunule and a distinct brown line at base of fringes. Beneath, golden yellowish, with a dusky median shade line on both wings. Expands 1.12-1.35 in. =: 28-34 mm. Habitat: Palmerly, Cochise County, Arizona, August. Two male and two female examples, all in good condition; from the collection of the Brooklyn Institute. I cannot identify this with any of the described species from Central America, and it is quite different from those of our own species thus far described. The frontal protuberance is umbilicate, the depression roughened. Schinia espea nov. sp. Head and thorax creamy ^-ith a reddish tinge; abdomen whitish. Primaries very pale creamy with a greenish tint, the shading olivaceoas. Basal area whitish to the t.a. line, which is very oblique inwardly and a little arquate, extending from beyond basal third of costa to within basal third of inner margin. The line is out- wardly shaded with olivaceous, which is darkest and broadest inferiorly, so as to slightly obscure the entire median space, the costal area being lightest, and fading out to the t.p. line. T.p. line from costa just within apex inwardly oblique, evenly bi-sinuate, to the outer third of inner margin. S.t. space very narrow, especially on costal margin, olivaceous, marking, by its contrast with the pale terminal space, an even but not at all defined s.t. line just about parallel to the outer margin. Fringes olivaceous. Secondaries white, sub-transparent, with a moderate blackish outer border. Beneath, white; primaries with smoky clouds over the costal area and s.t. space. Expands .96 in. = 24 mm. Habitat: INIiaco, Florida, September. One rather poor female out of a purchased lot, collector unknown. The species is an ally of hiundulata on the characters used by Hampson; but the course of the median lines is utterly unlike that of any other species known to me. Pseudacontia cansa nov. sp. Head and thorax a mottling of white and glossy gray scales, more white on the head than on thorax, and more white in the male than in the female. Abdomen gray, segments narrovsly white-ringed. Primaries smooth glossy gray, the median 120 ANNALS NEW YORK ACADEMY OF SCIENCES lines forming broad, rather even white bands in the female, becoming more diffuse inwardly iu the male. S.t. line whitish, very irregular, tending to become lost medi- ally, a little emphasized by brown preceding scales in some specimens; a patch of golden brown scales at the apex. A series of black terminal dots, fringes obscurely cut with pale. Orbicular a small black dot, Reniform a small black crescent at the inner edge of the white band forming the t.p. line. Secondaries smoky gray with a diffuse whitish median band, more distinct in the male, in which a dusky lu- nate discal mark is more or less obvious. Beneath, primaries smoky at base, becom- ing paler outwardly until they are white before a distinct broad, defined blackish s.t. band, beyond which the wing is again pale. There is a small black discal lunule. Secondaries whitish, with a narrow extra-basal dark band, a broader, blackish sub- terminal band, and a black discal lunate mark. Expands .94 -.98 in. = 2.3.5-24.5 mm. Habitat: Hamilton County, Kansas, 3500 feet (Professor F. H. Snow). One male and two females, in fair condition. I have been inclined to regard these as forms of crustaria INIorr. ; but the receipt of quite a series of the latter shows them to be distinct. The vestiture is smoother through- out, and, while the maculation is almost the same, there is none of the bright coloring or sharp contrast of the older species. The armature of the fore tibia is also somewhat different, forming distinct outer and inner claws, instead of a long inner claw wuth a marked outer angle of the flat corneous tip. Pseudacontia louisa nov. sp. Head and thorax rich yellow-brown mottled with creamy white and black scales; abdomen yellowish. Primaries creamy yellowish white marked and mottled with brown and black. Basal space brown-powdered, so that the pale ground is only just discernible; the basal line geminate, blackish, included space of the ground- color. T.a. line a broad band of the basal creamy tint, the anterior margin formed by the limits of the dusky base, the posterior a black scale line edging the brown median space; the line irregular, with a larger outcurve between veins 1 and 2, and a sharp inward tooth on vein 1. The median space is narrow, brown-powdered, with the round black reniform (which is annulate with yellow) fonning a conspicuous feature, the outer margin formed by an edging of black scales, of which the small lunate orbicular forms part and the irregular inner part of the t.p. line forms the remainder. Beyond this the wing is creamy to the brown terminal space, the s.t. space appearing bluish from the dark band of under side, the edges of which are a little marked by brown scales on the upper surface. S.t. line not defined, the termi- nal space narrow, and irregularly brown-powdered. A series of distinct black ter- minal lunules at the base of the long, brown, pale interlined fringes. Secondaries blackish, with a broad yellowish white median band in which is a large blackish discal lunate mark. Beneath, primaries mottled, blackish and yellow; a distinct, extra-median, broad outer band forming the most conspicuous feature. Second- aries pale yellowish, with a large blackish discal mark and a narrow, broken, irregular sub-terminal blackish band. A broken dark terminal line on all wings. Expands 1.10 in. = 27 mm. SMITH, NEW NOCTUID^ 121 Habitat: Sabine Parish, La. (G. Coverdale). A single male has been in my collection a long time awaiting a mate, and is now described because there seems no present hope of more material from the same region. It was a papered example, and the body is trans- versely flattened out of all shape; but the primaries are perfect and the maculation is clean and well defined. It is larger than crustaria with a similar t}^e of maculation; but in this the pale ground predominates, and the dusky s.t. space and more or less well-defined s.t. line are eliminated altogether. The anterior legs are w^anting in the type, and the generic reference is therefore made upon the basis of the general resemblance to crustaria. Annaphila miona nov. sp. Head and thorax bronze-brown with black and metallic-blue scales intermingled, forming no obvious ornamentation. Abdomen deep orange with narrow black dorsum, the edges of the segments narrowly orange. Primaries brown, mottled with black and metallic blue scales, the latter most obvious beyond the reniform and along the upper course of the s.t. line. Basal Une traceable by black scales. T.a. line geminate, black, more or less broken, included space a little paler than ground, outwardly oblique and with a distinct outward tooth in the sub-median interspace. Median line black, quite obvious, outwardly oblique and a little outcurved. T.p. hne, consisting of a very even brown band, very regularly bent over the cell, and an inner, broken, very irregular blackish line forming the outer border of the median space, and this is inwardly toothed on vein 2. The outer part of the wing is black at apex, shading to brown at anal angle; and through the black portion the s.t. line is very irregularly marked out by brilliant blue scales: below the middle the line becomes more even* and pale. Fringes brown with a black interline, beyond which they are checkered with black. Orbicular not obvious in the specimens. Reniform large, irregularly lunate, pale brown, ringed with white, with a whitish patch above it to costa, and outwardly three lobe-like extensions of the t.p. line filled with blue scales. Secondaries deep orange with a broad, even, black margin and a very faint basal line of blackish scales. No discal spot. Beneath, orange; primaries with a broad outer border, narrowing toward the angle, interrupted by a series of orange spots, and a broad median band from inner margin to center, where it breaks, and sends spurs toward costa and outer margin; secondaries with a broad black outer band in which a series of orange spots is traceable. Expands .80 in. = 20 mm. Habitat: Plumas County, California, June. Two females, in good condition save for lack of antennae. At first sight the orange of secondaries seems unbroken, except for the broad, solid, black outer band, and this forms a characteristic of the species. The faint blackish basal line becomes obvious enough when attention is drawn to it; but there is no black shading at the extreme base of the wing. 122 ANNALS NEW YORK ACADEMY OF SCIENCES Annaphila variegata nov. sp. Head and thorax bronzed brown mottled with blue and white scales, the latter tending to form a white tip to the collar. Abdomen orange, dorsum blackish, the segments narrowly orange-ringed. Primaries with basal area grayish brown to t.a. line; the median space, except reniform, darker, more or less blue- powdered; reni- form, and obliquely below to the imaer angle, white or very pale orange-yellowish merging outwardly into a dusky terminal and apical shade in which a black-edged s.t. line is prominent to the middle: the line itself consists of scattered white scales forming a white mark on costa, and beyond it are blue scales. Basal line dark chocolate-brown. T.a. line geminate, black or blackish, forming a sharp outward tooth in the sub-median interspace, and almost or quite meeting an inward tooth of the median shade; black scales connecting the two when they do not actually meet. Median shade line black, very irregular, keeping close to the t.p. line so far as that is defined below the reniform. T.p. line discontinuous, brown, and partly defined by the s.t. space from costa over cell, broken opposite the lower angle of the reni- form, where a loop-like extension of the dark median space forms the lower angle of that spot, then black, wath an inward angle on vein 2. Orbicular very obscure, round, concolorous, traceable by an outline of black scales. Reniform a large white or faintly orange blotch, inwardly and inferiorly defined, upwardly extending to costa, and outwardly merging into the s.t. space. There is a series of black termi- nal spots which tends to become sagittate above the pale area. There is a pale line at the base of the long fringes, which are brown with a black interline, and out- wardly checkered gray and brown. Secondaries orange-yellow, varying in depth; the males paler, with a broad black outer band ha\-ing an irregular inner margin, a more or less continuous narrow sub-basal band, and a black spot on the inner margin above the anal angle. Beneath, orange; primaries with a broad outwardly oblique black band, a black sub-marginal band which is broad from costa to the middle, where it touches the inner margin and is then very narrow and linear, and a black outer border, which is separated from the black fringes by a very narrow orange line; secondaries with a broken black inner line, a fragmentary median line indicated by two spots near inner and one on costal margin, a very irregular outer band more or less connected with the narrow black outer margin. Expands .88-.95 in. = 22-24 mm. Habitat: Placer County, California, 2500 feet. Five males and five females, in good condition and all very much alike. The males are uniformly a little smaller and less intensely colored, with the inner black band on secondaries more generally broken. There is no black discal spot on secondaries, and the maculation of the primaries is more like the yellow-winged forms than any other of the orange-winged species, except miona. Erastria puncticosta nov. sp. Ground-color verj"- pale ashen with a smoky gray powdering and overlay. Head and collar dark chocolate-brown, but varying toward the ground. Primaries with large brown costal spots at the inception of the basal, t.a. and t.p. lines, and beyond SMITH, NEW NOCTUIDM 123 the latter a series of alternate brown and pale marks to the apex. The basal line does not extend much below the costal spot. T.a. line single, narrow, broken, irregular, inwardly obhque. T.p. line single, broken, very irregular, outwardly bent over cell, and partly obsolete at that point. S.t. line pale, very irregular, preceded by a dusky shading, which may be emphasized by still darker, more sagit- tate spots. A series of black terminal lunules, beyond which the fringes are cut with pale. There is no obvious orbicular. Reniform a narrow black line or lunule, which may or may not be margined outwardly with whitish. Secondaries uniformly smoky brown. Beneath, smoky, varying in tint; the primaries always darker, with the white costal dots of upper side reproduced; the secondaries more whitish, tending to a dusky outer margin. Expands .60 -.66 in. = 15-16.5 mm. Habitat: New Brighton, Pa., July 22-Aug. 11. Nine examples, all males and mostly in good condition. The species at first sight resembles the deltoid species of Megachyta by the prominent brown costal spots. There is little variation in the examples before me, except in the amount of the dusky overlay. In the best examples this extends from just beyond the base to the outer margin, becoming gradually more intense, so that the pale s.t. line stands out clearly in contrast; in the poorest examples the dusky tint remains over the terminal area only, and the s.t. line loses in relative distinctness. The abdomen is smoothly scaled, with a small dorsal scale-tuft at base in the better specimens. Beneath, the legs are dusky and the tarsi narrowly pale-ringed. The species seems to be not uncommon at New Brighton, but I have none at present from other sources. Erastria humerata no v. sp. Head and coUar chocolate-brown; thorax and ground-color of primaries gray with an overlay of yellowish pale brown scales. Primaries with median space filled by a blackish-brown shading and a sub-quadrate patch of the same color on costa in s.t. space. Basal line brown, extending to median vein, and from it, to base of wing, is a dark chocolate-brown spot, which looks like the extension of the collar. T.a. line dark brown, irregular, a little inwardly obUque, outwardly diffuse, preceded by a whitish line or shade. T.p. line blackish, broken, irregular, abruptly and squarely exserted over the cell. This outward exsertion of the paler ground occurs beyond the linear black reniform, so that at first sight the t.p. line seems to cross the wing with only a slight outward curve. Outwardly the t.p. line is bordered by pale scales. S.t. line pale, very irregular, forming a broad inward angle opposite the cell, and an almost equal outward angle between veins 3 and 4. As a whole, the s.t. space is a little smoky, darkening to the large brown costal patch. Terminal space usually paler and a little more brown than the rest of the wing. A series of distinct black terminal lunules, beyond which the dusky fringes are cut with yellow- ish. Orbicular wanting. Reniform black, linear, upright. A series of three white dots on costa between t.p. and s.t. lines. Secondaries uniform smoky. Beneath, 124 ANNALS NEW YORK ACADEMY OF SCIENCES smoky; primaries darker, with the costal dots of upper side intensified and a larger one at inception of t.p. line; secondaries paler, with a large discal spot. Expands .58 -.64 in. = 14.5-16 mm. Habitat: New Brighton, Pa., July 11-31. Eight examples, in good to fair condition, all males; from Mr. H. D. Merrick. As in pundicosta, the antennae have the joints distinctly marked and feebly serrate, with obvious ciliae but no distinct tufts. There is also a small scale-tuft at the base of the abdomen, which is rubbed in most speci- mens. There is little or no variation except such as is due to the condition of the specimens, producing more or less contrast between the median and the outwardly adjoining areas. Erastria immuna nov. sp. Deep purplish brown or blackish over a pale base, the maculation black. Where- ever the purplish overlay has been marred, the whitish base becomes more or less evident. Primaries with basal line black, ob\'ious on costa, and emphasized by whitish scales outwardly. T.a. line black, single, velvety, a little outcurved in the interspaces, and on the whole a little inwardly obUque. Median shade black, nearly upright, a little diffuse, and beyond it the wing tends to a little mottling. T.p. line black, single, more or less lunulate, irregularly outcurved over the cell and inwardly bent below it, emphasized by a few pale scales. S.t. Une irregular, broken, pale, chiefly marked by a black preceding shade which is sharply defined on the line, but becomes diffuse inwardly. A series of black terminal lunules which may be emphasized by pale scales. A series of four white costal dots before apex. Fringes cut with pale opposite the cell. Orbicular wanting in the specimens. Reniform a creamy white lunule. Secondaries even, smoky gray. Abdomen smoky gray with a conspicuous black basal tuft on dorsum. Beneath, gray, powdery; primaries darker, with a paler terminal space; secondaries more whitish, with a small discal spot and a tendency to an exterior line. Expands .80 in. = 20 mm. Habitat: New Brighton, Pa., July 21, 28. Two males, in fair condition; from Mr. H. D. Merrick. The species is similar to muscosula in size and wing-form, but is much darker throughout, and darker than any of the other species known to me. Of the two examples before me, the one taken July 21 is almost uniformly purplish black with the pale reniform and the small whitish costal dots conspicuous; the speci- men taken on the 28th has the outer half of the wing distinctly pale-flecked, and this seems to be due to the removal of some of the surface scales. The species is therefore apt to be apparently variable, the more so as the black markings are composed of somewhat elevated scales. SMITH, NEW NOCTUID^ 125 Thalpochares fractilinea nov. sp.

Merrick. The species is narrower-winged and has longer palpi than the other American forms referred to this genus, and this may not be the best place for it. The primaries lack the accessory cell in the two specimens examined, and this de- termined the generic reference. . Homopyralis bigaUis nov. sp. Of the usual red-brown overlying a dull luteous, which becomes apparent when the specimen is flown? Maculation black. More or less black powdering, which usually darkens the basal space and may obscure the outer half of median space of primaries. Head and thorax marked with black and purplish intermingled scales. Primaries with t.a. line black, geminate, outcurved below median vein, inner part of line not distinct from dusky basal space. T.p. line geminate, inner portion lunu- late, more or less broken, rather squarely exserted over cell; outer portion incom- plete, in part reduced to a series of pale venular dots. A pair of waved black shade lines through the outer portion of median space, S.t. line pale, irregular, variably defined, preceded by a quadrate blackish patch on costal area. A series of black marginal followed by smaller, yellow terminal dots. Orbicular a small, round, soUd black spot. Reniform a large, solid black quadrate or oblong spot. Secondaries with the maculation of primaries continued across the disk, but as a whole nearer to the base than on primaries. There is a tendency to a purplish shading through the outer part of the wings.

Habitat: Hot Springs, New Mexico, 7000 ft., September; Yavapai County, Arizona, Aug. 8; Huachuca Mountains, Arizona, July 30; Palmerly, Arizona, without date. 126 ANNALS NEW YORK ACADEMY OF SCIENCES Four males and two females, in fair condition. The markings are more clearly defined and the lines are better separated than in the allied species. Superficially the larger size will at once make it recognizable. Epizeuxis intensalis nov. sp. Head, thorax and primaries deep, rich, lustrous smoky brown; on the head and thorax uniform, on the primaries overlying a pale, glossy luteous which appears through in places, and gives the wing a mottled appearance. T.a. line upright, with three equal outward teeth or angles only a little darker than the ground, and usually best marked by the preceding pale shade, which is variably complete and always diffuse. T.p. line sharply denticulate, with long outward teeth on all veins, only a little outcurved over cell and incurved below, best marked by the well-defined pale line which follows the obscure darker line. S.t. line very irregular, forming three main outward lobes and three long inward angles, the first outward lobe begin- ning at costa and extending to the inward tooth opposite middle of cell; the second lobe begins at the latter point, and extends to the inward angulations on veins 1 and 2; the third outward lobe is only partial, and extends to the inner margin. The terminal space is always paler than the rest of the wing, often mottled, and some- times contrastingly so. There is no obvious median shade. A distinct black termi- nal line, narrowly interrupted on the veins. Fringes smoky, narrowly cut with yellow. Orbicular a small round dot of the yellow ground-color. Reniform moder- ate in size, somewhat lunate, consisting of a dark crescent set in a larger spot of the pale ground-color. Secondaries whitish, with a yellowish or smoky suffusion, darker outwardly. There is a dusky median line followed by a pale shading, a pale sub-marginal line, and a distinct brown terminal line. Beneath, yellow, very sharply marked with a common black median line, a much fainter and variably evident s.t. line, and obscure discal spots. Expands 1.10-1.40 in. = 28-37 mm. Habitat: Yavapai County, Arizona, July and August (Hutson); South- ern Arizona, June 15-30 (Poling); Southern California (Poling). Six males and one female, in fair or good condition. This species resembles coheta Barnes at first sight, but differs from all others in the genus by the distinctly annulate reniform, the contrasting terminal space, and the sharply-marked under side. The secondaries also are paler than in any other of the allied forms, so that we have a fairly well-defined species in an aggregation of decidedly variable forms. Epizeuxis partitalis nov. sp.

Sci., Vol. XVIII, No. 3, Part II, pp. 129-146. 4 April, 1908.] ON DETERMINATION OF MINERAL CONSTITUTION THROUGH RECASTING OF ANALYSES.^ By Alexis A. Julien, Ph. D. Introduction. The recognition of the aggregate character of rock constitution, even in varieties of aphanitic texture, has led the analyst in recent years to rearrange the determined chemical components of a rock in the form and propor- tion of its existing mineral constituents. The now well-known advantages of this practice, in the bearing of its results on the true character and probable origin of a rock, are bringing about a complete revolution in petrographical science. The day of the representation of the material of a rock by a mere report of its chemical analysis has now passed. The early mineralogists were accustomed frequently to transpose analyses of a mineral substance into the proximate mineral constituents known at that time, such as calcareous minerals and ores into various carbonates and oxides. With the silicate minerals however the increasing list of known minerals soon became burdened with an indefinite series of hypothetical compounds, proposed by Rammelsberg, Tschermak, Knop and their suc- cessors. The difiiculty and uncertainty attending the use of these, in interpretation of chemical analyses, have perhaps served to discourage the continuance of the ancient method; so that at present the discussion of the chemical composition of a mineral generally ceases with presentation of its analysis, accompanied by oxygen ratios and a formula. A chemical analysis alone, particularly of a complex compound, such as a silicate, rarely conveys — even to the eye of an expert mineralogist — much more than a vague guess or estimate of the distinctive character of the combination. A glance, for example, over an analysis of a chlorite, sepa- rately presented, would hardly enable him to assign it with any certainty to the page-full of selected but widely varying analyses of penninite or to those of clinochlore or to those of prochlorite comprised in every treatise 1 Presented to the Academy at the meeting on 6 January, 1908. 129 130 ANNALS NEW YORK ACADEMY OF SCIENCES on mineralogy, now seriously offered to us in illustration of the fixed theo- retical composition of each of those minerals. Nor is the certainty increased in very many cases by deduction of the actual ratios existing between the components included in the chemical analysis of a supposedly pure mineral. A chemical formula merely marks a possible relationship and may be but a blind and even misleading guide. The extraction of a formula is not confined to an independent mineral and is not a certificate of homogeneity. Whatever the figures of an analysis obtained from a pinch of soil or clay or from a fragment of brick, it would go hard with any analyst if he could not devise therefrom some skeleton of a formula. Yet these spectral shapes hover over all the early history of mineral analysis, and their existence is often brought forward as the chief, generally as the sufficient evidence to justify promulgation of new mineral names or supposed new reactions in mineral genesis. It is obvious that the initial process in the calculation of a formula, i. e., division of the percentage of each component by its molecular weight, is one that tends to reduction of the comparative proportion of the minor components, and thus to minimize and conceal the lack of homogeneity in a substance subjected to analysis. An investigation of mineral material therefore which ends with the presentation of the bulk analysis, even with an annexed calculation of oxygen or molecular ratios and formula of the crude aggregate, is surely incomplete. Constitution of Crystallized Minerals, The prevailing method of the analytical chemist, just discussed, seems to have been founded upon two exaggerated views concerning the constitu- tion of crystallized minerals: 1. The assumption of their practical homogeneity and purity, an error which has crowded the literature of the science with hordes of discordant analyses and a series of poorly described and uncertain species. The revelations of the microscope, particularly by means of polarized light, have long since established that a mineral, however well crystallized, often even when limpid and free from visible enclosures, may be but an aggregate, with one constituent in predominance in selected specimens, enveloping a number of others. In the same association or vein, particu- larly in vicinity of the matrix or vein-wall, phases of intermixture with increasing amounts of the minor constituents commonly pass into less perfectly crystallized forjns of the first predominant unit, and often into earthy or massive aggregates in which one or another of the associates rises JULIEN, DETERMINATION OF MINERAL CONSTITUTION 131 into greater or prevailing proportion. Familiar examples of these transi- tions are found in the endless variations of intermixture of quartz, even within its crystals, with hyalite, iron-oxides, rutile, chlorite, etc.; the inter- inclosure, intergrowth and inter-twinning of the feldspars in aggregates of the most complex constitution, and the similar mutual envelopments of the metallic sulphides. The possibility of even "ideal purity" of a mineral has been based largely on results of examination of material selected for chemical analysis. The precautions usually taken to insure freedom from impurities are proba- bly shown fairly in those long ago described by Doelter.* The fragments were first examined by the naked eye and then under a hand lens. A thin section was prepared and inspected. Splinters and cleavage-plates in different directions were then spread on a glass slide and examined by transmitted light under a low magnifying power of the microscope. By these means, it was believed, the visible purity of the material was insured, or, if impurities could still be detected but not removed, they were identified and allowance made for their amount in the reduction of the analytical figures. In the light of present knowledge all these precautions appear insufficient to insure purity. From the subtle revelations of existing intergrowths now obtained through polarized light — the absolute concealment of all foreign inclosures within subtranslucent and opaque specimens — and, in every case, the escape of microscopic inclosures from observation, whatever their abundance, whose minute dimensions fall below the resolving power of the microscopic lens — the natural conclusion follows that the most effective detection of inclosures must be sought through study of the relationships of the chemical components of the mineral. 2. The usual mode of application of purely hypothetical compounds in rearrangement of components. Without questioning the propriety of their consideration in reconstruction of an analysis, little seems to be gained toward real explanation of lacking relationships, by excessive resort to imagined compounds, like Mg Fcj'" SiOg, Fcj Fe/'' Sig O^j, and others, in pyroxene, which have never been dis- covered in nature, in isomorphous interlocking with others, like CaMg SigOg, whose co-existence as actual minerals is proved by optical behavior. In such cases, a conviction of the extent of dissemination of existing minerals as inclosures will lead rather to more persistent search for the latter, and, I think, more satisfactory solution of difficult problems constantly presented in recasting analyses. An analysis then is not the end, but it is only a step toward the discovery of the existing mineral constitution. As the chemical composition of an 1 Min. u. petr. Mitth., I, 49, 67, 373. 1878. 132 ANNALS NEW YORK ACADEMY OF SCIENCES established mineral species is fixed, the possible object of analysis of a specimen identified by other means may be two-fold : determination of any replacements of components in the chief mineral ; and demonstration of the constitution of other minerals which may be intermixed in the aggregate. The latter may be of great importance in elucidation of genetic history and relationships of the chief mineral. Several methods have already been devised and applied toward quanti- tative determination of the elements of such intergrowths or aggregates: such as the graphic methods for measurement of their respective areas in a microscopic field, by means of drawing or photography; that of separation of the elements in a crushed aggregate by suspension in a dense liquid; that of separation of ferruginous minerals from a pulverized aggregate by means of an electromagnet; that of separate chemical analysis of the por- tions of an aggregate soluble and insoluble in an acid; and that of com- parison of the simplified bulk analysis with a series of hypothetical chemical compounds. The first two methods are inapplicable to aggregates whose granulation is microscopic; the next two are limited and imperfect, through dependence upon a single character, and the last is subject to the errors usual to excessive reliance upon hypothesis rather than upon data of obser- vation. A more simple and effective method, in many cases, is that shown in the practice of the early mineralogists. Within every chemical analysis of a mineral substance lies the Key to its constitution. For its completion a re-arrangement or recasting is needed to determine the existing minerals as combinations of stated components. This can be carried out where the data are fairly complete, sometimes with great ease, and the results tend toward solution of long mooted problems and elucidation of the character of admittedly doubtful mineral species. Modern examples of a return to this earlier practice have been offered in late studies of certain varieties of pyrites, feldspars, spodumene and, more recently, jade. Recast Analyses of Minerals. A few simple illustrations, taken from a series of calculations now at hand, will suffice to show the ease of the long-neglected method and the value of its results. In connection with each analysis, as published, my estimate of the approximate mineral constitution is appended. In con- formity to the description of the mineral, the alumina has been assumed, in these particular examples, as the basis for calculation of the amount either of a chlorite or of an aluminum hydrosilicate, using the theoretical composition which may correspond to the accepted formula of each mineral. JULIEN, DETERMINATION OF MINERAL CONSTITUTION 133 The following is presented as a good example, on the one hand, of the deceptive appearance which may be assumed by a chemical analysis, and, on the other, of the corrective evidence supplied by optical examination of the same specimen.

It appears therefore that this mineral is in fact a serpentine comparatively free from impurities. When reduced to the proper thinness it was found that the material was far from homo- geneous. A portion as seen under the microscope appeared absolutely colorless by transmitted light, while the remainder was of yellowish and brownish tints, in spots almost opaque, although by reflected light this posi- tion retained the pale apple-green color of the hand specimen .... clouded by the presence of extremely microcrystalline particles" (Mon.

Those substances in particular which are apparently amorphous seem to have led to the greatest misapprehension and error, which may now be removed by similar treatment of their analyses. In the absence of outward crystalline form they present two alternatives: they may be considered as possibly either truly colloidal and optically isotropic, like obsidian; or as microcrystalline but mostly homogeneous aggregates. In either case the so-called "impurities" must be present. In the micro-aggregates, even though one mineral may predominate, it is always safe to .presume that admixture with other minerals does occur in varying but notable proportions. In this respect it matters nothing whether an aggregate be macroscopic, with constituents visible to the naked eye, or microscopic or even ultra- microscopic; the limitations of our vision or optical instruments have no bearing in any way on the settlement of homogeneity and of the question of intermixture. It is true that in descriptions of minerals many micro-aggregates have been cautiously assigned to subsidiary lists or groups, imder such headings as "Chloritic minerals more or less imperfectly defined," "Magnesian silicates allied to serpentine but of somewhat doubtful character," and "Appendix to hydrous silicates." Yet the same pages are crowded with the names of impure aggregates, figuring as minerals, mainly because amor- phous and somewhat uniform in color and other characters, particularly if this conclusion has been buttressed by construction of chemical ratios or formulas from the analyses. Micro-aggregates are likely to comprise a larger number and proportion of chemical components and of their combinations than those found in crystals. The proposed solution of their constitution does not consist merely of a calculation of the possible mineral combinations of a certain number JULIEN, DETERMINATION OF MINERAL CONSTITUTION 137 of chemical components; that process might be almost endless. It is restricted to a careful discrimination of the probable proximate compounds, i. e., simpler existing minerals, consistent with the physical and optical characteristics possessed by the micro-aggregate. Furthermore, when the associations of this aggregate and the probable conditions attending its formation are knowTi, the identification of the constituent minerals may be facilitated by restriction to the class of minerals developed in certain vein or gangue formations or in a particular metamorphic zone: for example, the constituents of the "diabantite" mixture to the series of minerals de- veloped in the belt of weathering and there only. In a study of the hydrous silicates, almost completed, to which this paper is a partial introduction, I have prepared a tabulated list to indicate the possible mineral combinations which may logically be sought for in micro-aggregates of this particular class. Taking for present examples in illustration of these views the micro-aggregates of magnesian hydrosilicates of the belt of weathering or decay — one of the groups of amorphous mix- tures of the most difficult resolution — the following are some of the chief indices for detection of the combinations in which the more common com- ponents may occur. Silica in three forms : a) colloidal and soluble, in combination with a large proportion of water, e. g., disilicic monohydrate, HjSijOg, containing 13.05 per cent, of water, or trisilicic dihydrate, H^SigOg, containing 16.67 per cent, of water; h) hyalite or opal, containing 2 to 13 per cent, of water and insoluble, and (c) this, passing through various intermixtures, as semi- opal, chalcedony, etc., into anhydrous and insoluble crystalline quartz. Alumina: a) where silica is scanty, as one of the two aluminum hydrates (bauxite, gibbsite); h) with silica abundant, as a residual remnant of an aluminous mineral (pyroxene, mica, feldspar, etc.) or as one of eight alu- minum hydrosilicates (allophane, halloysite, talcosite, etc., but perhaps not kaolinite) ; c) in presence of alkaline and earthy bases, as a newly formed chlorite or zeolite (a restricted list, prochlorite, stilbite, natrolite, etc.). Ferric oxide: a) with silica scanty, as anhydrous oxide (hematite, but never magnetite), or as one of the four ferric hydrates (limonite, limnite, turgite, gothite); h) with silica abundant, as one of the three ferric hydro- silicates (hisingerite, chloropal, anthosiderite), or as an aluminum-ferric hydrosilicate (?). Ferrous oxide: a) commonly in replacement of magnesia, sometimes as siderite or other carbonate; h) with silica abundant, as one of the two ferrous hydrosilicates (ekmanite, chloropheite of Forchhammer) ; or (c) as the aluminum-ferrous hydrosilicate (aphrosiderite). Manganese oxide: a) as manganous oxide (manganosite), sesquioxide 138 ANNALS NEW YORK ACADEMY OF SCIENCES (manganite) or dioxide (pyrolusite) ; b) as hydrate (pyrochroite) and car- bonate (in wad, rhodochrosite, etc.) ; c) with siHca abundant, as manganese hydrosilicate (bementite). Lime: a) as a residual remnant of one of the calcareous silicates (augite, diopside, tremolite, anorthite, etc.); b) as carbonate (calcite) or calcium- magnesium carbonate (dolomite, ankerite) ; c) with silica abundant, as one of the newly formed calcium hydrosilicates (gyrolite, okenite, xonotlite), or as aluminum-calcium hydrosilicate, (sloanite ?). Magnesia: a) with silica scanty, as oxide (periclase), hydrate (brucite), ferro-magnesium hydrate (p\'Toaurite), aluminum-magnesium hydrate (hydrotalcite), magnesium carbonate (magnesite, breunerite, mesitite) or hydrocarbonate (hydromagnesite, hydrogiobertite, etc.); b) with silica abundant, as one of two of the magnesium hydrosilicates (deweylite, sepiolite) or as aluminum-magnesium hydrosilicate (pyrosclerite). Alkalies: with alumina and ferrous oxide (as a chlorite); with lime, as a hydrosilicate (certain zeolites). It should here be noted that in a study of micro-aggregates of a different origin, e. g., from development within a lower zone of metamorphism, a quite different series of constituent minerals would need to be considered. The preparation of any such series, in the present incomplete knowledge of the conditions of origin of mineral species, would require careful investiga- tion of associations, relationships and all other evidence at hand. One conclusion from such study will be remarked in the series above given: that many minerals, the occurrence of which in distinct and crystallized specimens has been set down by the mineralogist as uncommon or even very rare {e. g., brucite, periclase, deweylite, gyrolite, anthosiderite, etc.), may yet be shown to occur abundantly, in dissemination through rock formations and mineral aggregates in obscure or entirely invisible forms. In calculation of mineral constitution from the analyses of such micro- aggregates, the chemical formulas of the constituent minerals, so far as they have been determined with certainty, may be accepted and used as absolute, and as far preferable in most cases to any actual analysis of a mineral, on account of the universal intermixture of impurities in the latter, even in the best crystallized and apparently purest specimen. The facts show, in my opinion,that all mineral substances have a definite composition and character, that none are intermediate or transitional, that even from decay or other mode of dissociation of a complex mineral com- pound only independent minerals of simpler but exact composition are derived. If this be true, we shall have little need of resort here to h}'po- thetical chemical compounds but may perhaps rely entirely on determined formulas for all calculations of mineral constitution. JULIEN, DETERMINATION OF MINERAL CONSTITUTION 139 It has been already intimated that one result of loose and vague mis- apprehension of the essential and non-essential chemical components of a crystallized mineral, or of the predominant mineral in a micro-aggregate, appears to have been that the limitations in the laws of replacement in the composition of a mineral have not always been clearly recognized; inclo- sures have been mistaken for replacements. For example, in the two basic magnesium hydrosilicates, deweylite and antigorite, magnesia may be replaced by ferrous oxide, by manganous oxide, and probably by lime, but never by metallic oxides. Recast Analyses of Micro-aggregates. A few examples of micro-aggregates, taken from my notes on minerals of the magnesian hydrosilicate group, are presented below. They have been selected to illustrate a variety of mineral constituents, identified in these mixtures by this simple method, in contrast with the chemical formulas on which the present acceptance of these mixtures as possible or certainly independent minerals has been largely founded.

It can be claimed for hardly any one of the examples given above that more than an approximation to the truth has been presented. With the im- perfection of both analyses and descriptions as published, each interpretation yet calls for special tests of the very specimens of these micro-aggregates used in the analyses, for confirmation: e. g., strong alkaline reaction or other evidence of free magnesia in "picrofluite" and " diabantachronnyn," and optical identification of prochlorite, chloritoid, etc., in the others. It is certain that, in each of the specimens represented by these analyses, there existed a certain intermixture of minerals the identity and exact proportion of which should have been identified by the analyst. For such determina- tion in any analysis certain accurate data are indispensable. In place of the usual meagerness in description of physical properties, omission of optical examination and common imperfection of the chemical analysis itself, it is obvious that, in a proper investigation of any mineral, its complete examination, physical and optical, should precede on the very specimen used for the chemical analysis. Only under such conditions can exact results be obtained from the universally heterogeneous materials which are found in nature. It seems likely, however, from the results above shown, through this old simple method, toward disclosure of latent mineral con- stitution, that it may prove of advantage even if now applied to the series of mineral substances whose chemical analyses have been published. i [Annals N.

The production of sounds by certain fishes has long been an interesting subject of investigation. Some species, as Scomber brachyiirus, by rubbing together the pharyngeal teeth make a noise resembling a harsh grunt; some, as the puffer, or swellfish, make a similar sound by rubbing together the incisor teeth of the upper and lower jaw. In other cases stridulation has been recorded, and sounds are also said to be produced by the forcing of air through the pneumatic duct in those fishes in which the air-bladder 1 Read by title at the meeting of the Academy on 13 April, 1908. 149 150 ANNALS NEW YORK ACADEMY OF SCIENCES communicates with the exterior. Besides these kinds of sound production, which are of no special interest in this discussion, there are tu'o others. One is the drumming of the squeteague, croaker and other drumfishes (Scisenidse) ; the other is the so-called grunt of the sea-robin (Prianotus) and the common toadfish (Opsanus). With the difference in the kind of sound made by the drumming and the grunting fishes there will be found to be a distinct difference in the structure of the swim-bladder, which is the organ chiefly involved in the production of sound by these species. Anatomy of the Swim-Bladder. The Drumfishes. Bearded drum {Pogonias cromis). — The swim-bladder of the drum is characterized by its large size and the enormous number of its diverticula. The bladder occupies, as is the case in nearly all of the sciaenoid fishes, the entire length of the abdominal cavity. The diverticula are finger-like processes which arise laterally from the bladder and open into its large cavity. These tube-like appendages in the adult ramify through the con- nective tissue, and in many cases adhere firmly to the aponeuroses of the neighboring muscles. The air-bladder itself lies free in the abdominal cavity, attached on the dorsal side to the body of the fourth vertebra and covered on the ventral side by the peritoneum, which is continued from the parietal walls. When examined carefully, the air-bladder is seen to be made up of three layers: the outside is of a hyaline character and is com- posed of extremely tough fibrous tissue; the middle layer, which is sepa- rated from the outer layer only with great difficulty, is connective tissue containing elastic fibres ; the inner layer is a very delicate connecting tissue, lined with pavement epithelium. Jager (1903) has recently discovered that this inner layer does not cover the entire bladder-lumen, but on the dorsal surface there is an oval space in which the inner layer disappears, with the exception of the pavement epithelium. This space he calls the "oval," and maintains that it can be increased or diminished by the action of small muscles. In the middle layer ramify all the blood-vessels, which break into small branches and then enter the inner layer, where, in the region of the "oval," they form an anastomosing capillary net-work almost as complete as is found in the "red-body." This net-work is thus sepa- rated from the lumen of the air-bladder only by the single layer of pavement epithelium. The function of the "oval," according to Jager, is the ab- .sorption of oxygen and the diminution of the amount of gas in the bladders TOWER, PRODUCTION OF SOUND IN CERTAIN FISHES 151 of fishes having no pneumatic duct. Thus the "oval" and the pneumatic ducts serve tlie same physiological function. Adhering to a portion of the dorsal surface of the air-bladder, just posterior to the point of attachment to the vertebrae in the male, is the central tendon of the two red drumming muscles.^ Upon opening the bladder of the drum, there is found on the inside, running almost the entire length, the red vascular body vv'hich has been described as the blood gland, or "red body." Squeteague {Cynoscion regalis). — In the squeteague the swim bladder (fig. 1) is a long carrot-shaped organ, tapering to a point at the posterior end, and sending out from the broad anterior end three diverticula — two lateral horns and a central rounded "head." The dorsal surface of the "head" is attached by its outer or fibrous tunic to the sides of the body of the fourth vertebra, which broadens out to receive it. The lateral appen- dages of the swim-bladder of the drum are wanting in the air-bladder of the squeteague, which has nothing to mar its smooth even contour except the two lateral horns already described, which arise from the most ante- rior part of the organ. On the inside of the air-bladder is found the char- acteristic "red-body," or "blood-gland," which is present in the drum. The drumming muscles are present in the male squeteague only. Their insertion is lateral in the common fascia of the rectus abdominis muscle, about a half-inch from the mid-ventral line. The muscles, one on either side, are bilaterally symmetrical and originate from a central tendon, which lies free in the mid-dorsal line just above the swim-bladder and between it and the kidney. The anterior extremity of this central tendon is inserted by its middle third into the dorsal surface of the neck of the swim-bladder, while the right and left thirds merge into the fascia that support the peri- toneum. Posteriorly, in the region of the anus, the tendon narrows down to a cup-shaped extremity that receives the tip of the swim-bladder, and then gradually tapers to a point, which is inserted into the base of the first anal fin-ray. A closed cavity is thus formed, bounded laterally by the two drumming muscles, ventrally by the confluent abdominal muscles, and dor- sally by the central tendon. This closed bag or cavity contains the viscera ' Dufossg (Annales des Sciences Naturelles, ser. V, vol. XIX. 1874, p. 39) has described in Trigla lyra two red muscles which he called intra-costal muscles. From his description I am unable to identify them with the "drumming muscle" just mentioned. In no case has it been possible to find these "drumming muscles" in any of the Triglidce. Dufoss6 attributed to these intra-costal muscles the function of motor agents of the skeleton. "Considgres uniquement comme agents moteurs du squelette, ces muscles intra-costaux ont evidemment pour functions: d'une part, de fl6chir latSralement ou de maintenir I'gpine dorsale dans sa rectitude ordinaire, suivant qu'un seul muscle se contracte, ou bien que la contraction de ces deux muscles est simultange, quand les os scapulaires leur servent de point fixe; d'autre part, d'attirer en dedans ces derniers os, et par suite les scapulaires et les humeraux, (Cuvier), lorsque la colonne vert6brale est pr6alablement fix6e." It is evidently from this supposed function that Dufoss6 gave the name of intra-costals to these muscles. 152 ANNALS NEW YORK ACADEMY OF SCIENCES and swim-bladder, the latter having the "central tendon" directly applied to its dorsal surface. The blood-vessels and nerves supplying the drumming muscles are only 771 S VV-S Fig. 1. Swim-bladder of Cynoscion regalis. The two m. sonifici (m s) are shown laterally displaced, h, head; 1, lateral horn; c t, central tendon of m. sonifici. accessory branches from the arteries and nerves of the abdominal muscles. An embryological study of the origin of these accessory blood-vessels and nerves and their relation to the muscle at the time when it is first laid down TOWER, PRODUCTION OF SOUND IN CERTAIN FISHES 153 would be instructive. For the drumming muscles the name musculus sonificus has been suggested and is used in the following discussion.^ In young squeteague two inches long, it is impossible to distinguish macroscopically a differentiation of this muscle. But if a piece of the peri- toneum with the underlying fascia is removed and examined under the microscope there are seen striations typical of voluntary muscles. The muscle fibres run in the direction of the short diameter of the fish, i. e., circularly around the air-bladder. These young squeteague have been heard to "drum," and the contractions of the m. sonificiis can be easily felt when the fish is held firmly in the hand. In the young this muscle has not acquired the deep red color that so characterizes it in the adult. &I> a. Cim of of air- air- msv. Lateral horns bladder. Hinder point bladder. The muscles which must make the air-bladder act as a sound pro- ducing organ. Fig. 2. Swim-bladder of Micropogon unduiatus after Sorensen. Croaker (Micropogon undulatus). — Another scisenoid, known in Amer- ican waters as the croaker, is of interest from an anatomical standpoint. The difference between the bladder of this fish and that of the squeteague, except for its being considerably smaller, is that the central head is not present, and the two lateral horns are reduced to two very small tubes. It is therefore an even more simple organ than that of the squeteague. The two bilateral sonifici have the same arrangement in both animals, and the description of the muscles of one applies equally well to those of the other. Sorensen states that "the form of the air-bladder needs no other description than that given in figure 9" (a copy of which is here appended as fig. 2). 1 Dr. Hugh M. Smith and Dr. Theodore Gill suggested several anatomical names, from which musculus sonificus was selected as being the most appropriate. The author is greatly indebted to these two well-known ichthyologists for their assistance. II' 154 ANNALS NEW YORK ACADEMY OF SCIENCES Sorensen made his dissection on one specimen preserved in alcohol, con- sequently the diagram is somewhat misleading, as can be seen by com- paring it with the bladder and muscle taken from a fresh specimen (PI. VI. fig. 1). Bridge uses this figure from Sorensen to verify the following state- ment: "In other fishes, the air-bladder, without possessing special muscles of its own, may, nevertheless, be partially invested by tendinous or partly muscular and partly tendinous, extensions from the muscles of the body wall." This muscle (m. sonificus) cannot be considered an extension of the muscles of the body wall but a unique, specific muscle which has been developed for the purpose of sound production. The muscles with the aponeuroses are united with the swim-bladder by means only of a tendon on the dorsal side immediately anterior to the base of the horns, and in no way attach themselves directly to the bladder, which is completely sur- rounded by the muscles and tendons. Sorensen states: "According to its structure, the air-bladder of this fish must be a sound-producing organ. Most probably the contractions of the muscles will, for a moment, compress the air-bladder and strain its dorsal wall, each of which operations must separately be able to bring the air-bladder to produce sound." Sorensen did not make any physiological experiments and based his conclusions entirely upon anatomical data. In the light of experiments soon to be described it is evident that he did not understand the "drumming" mech- anism. OtJier drumfishes examined. — Through the courtesy of Dr. Hugh M. Smith (1905) of the Bureau of Fisheries, it has been possible for me to examine specimens of the southern squeteague {Cynoscion nehuhsum, PI. VI, fig. 2), the yellow-tail (Bairdiella chrysura, PI. VII, fig. 1), and the spot (Leiostomus xanthurus, PL VII, fig. 2)} The anatomical relations of the air- bladder and the m. sonijicus are so similar to those noted above that no further description is necessary. In the spot the peritoneum is so pigmented with black that the m. soiiificus is somewhat hidden. The Sea-Robin and the Toadfish. In these fishes there is found a swim-bladder which is so radically dif- ferent in its outward appearances from that of the scitenoid fishes, and at the same time is so characteristic, that attention is immediately attracted to this organ. The sound produced, described as a grunt, differs markedly in character from the drumming of the Scisenidie. 1 These drawings were made from dissections completed by T. E. B. Pope of the Bureau of Fisheries. TOWER, PRODUCTION OF SOUND IN CERTAIN FISHES 155 Dufoss6 (1874) in his memoir on "Sons Expressifs Produits par les Poissons d 'Europe" has given an accurate and complete anatomical de- scription of the air-bladders of the European Zeus faber, Dactylopterus volitans and various Triglidne. Inasmuch as the air-bladders of the Trig- lidse of the North American waters differ in some respects from those de- scribed by Dufosse, I will here state briefly the structure in the species under examination, Prionotus carolinus, or the red-winged sea-robin, as well as of Opsamis tan, or the common toad-fish. Sea-robin {Prionotus carolinus).— The air bladder of Prionotus (Fig. 3) A B Fig. 3. SwiM-BLADDER OF PrIONOTUS CAROLINUS. A, Viewed externally, i m, intrinsic muscle; c I, connecting lumen. B. Longitudinally bisected, r, right lobe; g, internal septum; c o, central open- ing of septimi. is a deeply bi-lobed organ, occupying about two-thirds the space of the abdominal cavity. The two lobes are connected near the anterior end by a rather small tube. Along the outside portions of the respective lobes is found a muscle, red in color, and running from the anterior end of the lobe to the posterior end. The muscles adhere strongly to the underlying coat of the air-bladder, and can be separated from it only with difficulty. The muscle-fibres run in the plane of the short axis of the bladder. These muscles correspond to the "intrinsic muscles" of Dufosse. The bladder 156 ANNALS NEW YORK ACADEMY OF SCIENCES is not connected with the exterior by a pneumatic duct, Giinther (1880) to the contrary notwithstanding, for the entire bladder has been removed from the abdominal cavity without losing any of the contained gas, an operation which would be impossible if there were any means of commu- nication between it and the exterior. The air-bladder itself consists of three layers — an external, a middle and an internal — together with the pair of muscles just described. The outer and middle layers are composed of thick, compact tissue, containing both elastic and non-elastic fibres. The inner membrane is a mucous im IrT/h A B Fig. 4. Swim-bladder of Opsanus tau. A. Viewed in situ, i m, intrinsic muscle. B. Viewed externally. tissue provided with numerous blood vessels. Lying in this tissue are found also the blood glands or red-bodies which were described in the bladders of the scitenoids. The left lobe (fig. 3 B) in all specimens of Prionotus is divided into two parts by a partition formed of the internal tunic or membrane. In the centre of this partition is a small opening, a little larger than the head of a pin. The right lobe is never divided. This perforated partition was present in all specimens examined of both sexes. The cmbryological TOWER, PRODUCTION OF SOUND IN CERTAIN FISHES 157 history of this partition has never been investigated. There is no difference in the structure of the swim-bladder in the male and female, the intrinsic muscles being present in both. It is evident that we have here anatomic- ally a very different structure from that in the swim-bladder of the Scise- nidse, a fact which will play a very important part in the interpretation of the physiological experiments soon to be described. |;i Toad fish (Opsamis tau). — The swim-bladder of O'psanus (fig. 4) is relatively a much smaller organ than in Prionotus. When examined ex- ternally (fig. 4B), it seems to be deeply bi-lobed on the anterior half; but when viewed in longitudinal section (fig. 5), it is seen that less than one half of the organ is actually divided. The swim-bladder is supplied with ■im' CO ini' A B Fig. 5. SwiM-BLADDER OF OpSANUS TAU. A. A specimen longitudinally bisected showing the position of the internal septum (s). c o, central opening of septum; i m, intrinsic muscle. B. Another specimen longitudinally bisected showing the variation of the internal septum (s) . the same intrinsic muscles as that of the sea-robin. The muscles arise at the most anterior part of the right and left lobes respectively, and are separated posteriorly by only a small tendon. The muscular tissue is thick and strong, the fibres running transversely to the long diameter of the swim-bladder. An internal septum divides the bladder into two parts, an anterior and a posterior. The septum is perforated by a small opening, which forms the only means of communication between the two cavities. In the posterior cavity alone is found the blood gland. Most interesting is the great variation found in the position of the trans- verse septum in different specimens. In some cases, the partition is fully 158 ANNALS NEW YORK ACADEMY OF SCIENCES one-third of the distance from the posterior end (fig. 5 A) while in others it is less than one-sixth of the distance (fig. 5B). Indeed, in the large number of specimens examined, no two were found to be alike. Whether the vari- ation is accompanied by any change in function, I was unable to determine. Sound Production in the Dnimfishes. Recorded Observations and Theories. It has been noticed by many fishermen that the common squeteague at times makes a very plain and unmistakable drumming noise. As to how this noise is produced they can give no explanation nor is there any account of it in scientific literature, with the possible exception of Dufoss6's memoirs, which seem to be too little known at the present time. Their observations do not tell us whether it is the male^, female, or both that produce this characteristic noise. In the anatomical discussion, it was found that only the male was supplied with the red drumming muscle which, from its relation to the air-bladder, was considered to be connected functionally with the latter organ. Further observations demonstrated that the drumming occurred only in those animals in which this red muscle was present — that is, in the male squeteague. In some other species, as Micropogon undulatus, drumming occurs in both male and female, aid likewise the m. sonifici are present in both sexes. In the rather limited amount of study that has been given to the noises produced by these fishes, some of the conclusions are mere deductions from anatomical data, without any experimental or physiological proof. In other instances, the authors confuse the sounds produced by fishes of entirely different orders, and which have swim-bladders both anatomic- ally and pliysiologically different. For this reason it is very difficult to de- duce correct conclusions from their writings. As noted in a previous paper, Aristotle spoke of fishes that produce sound by some mechanism involving their air-bladder. The fact was thus known to fishermen and scientists very early; but no scientific explanations were offered nor were any experiments made which would account for these noises. Cuvier (1834) writes that "these fishes [scisenoids] swim in a troop and send forth a bellowing louder than that of the gurnards, and ' Since the above was written Dr. H. M. Smith has published the results of some obser\-a- tions, which show that both male and female of Micropogon make the drumming sound and that the male only in Pogonias, Sciwnops, Cynoscion, Leiostomiis and Bairdiella produce the drumming sound. (Science, vol. 22, 1905, p. 376.) TOWER, PRODUCTION OF SOUND IN CERTAIN FISHES 159 it has occurred that the fishermen, guided by their noises alone, have taken twenty scioence at a single throw of the net." The fishermen assure us that the noise of the scmnce is suflSciently loud to be heard through twenty fathoms (120 feet) of water, and that they are careful from time to time to place their ears over the edges of the boat, that they may be directed by the noise. Some say that it is a dull humming sound ; others that it is a rather sharp hissing. Some fishermen contend that the males alone make this noise in spawning time, and that it is possible to take them by imitating it and without employing any bait. That these fishes do produce noises that can be heard long distances is an undisputed fact. The fish of this family best known to us is the "weak-fish," described by Dr. Mitchill under the name of Labnis squeteague. It was known by the Narragansett Indians as the squeteague; and by the French of New Orleans as the trout. The fishermen of Cuvier's time "attributed to it certain dull sounds similar to that of a dnun, which are heard sometimes under the water and only in the season Avhen it is abundant." Another sound-producing fish of American waters which is described by Cuvier is the drum {Pogonias croviis). Cuvier states that "various accounts are given concerning the nature of the noise of these drums." According to Dr. Mitchill, it is when they are taken out of the water that they send forth this noise, but Schoepf says that "it is under the water that this noise is dull and hollow; that several individuals assemble around the keel of ships at anchor, and that then their noise is most sensible and continuous." This agrees with the report made by Lieut. John White, U. S. N., in 1824, in which he describes how his crew and himself, while at the mouth of the river Cambodia, were astonished by some extraordi- nary sounds which were heard around the bottom of the boat. It was like a mixture of the bass of the organ, the sound of bells, the guttural cries of a large frog and the tones which imagination might attribute to an enormous harp; one might have said that the vessel trembled with it. These noises increased, and finally formed a imiversal chorus over the en- tire length of the vessel and the two sides. The natives told Lieutenant White that the noises were produced by a troop of fishes. M. Humboldt describes a similar phenomenon in the South Sea on February 20th, 1803. Towards seven in the morning, he says, the whole crew were awakened by this extraordinary noise, which resembled drums beating the air. It was afterwards learned that the noise was produced by one of these sciffinoids. Cuvier, in speaking of the same species, states that, "it would be an object of curious research to find out the organs in these fishes which seem to pro- duce such strong and such continuous sounds, and that at the bottom of the water and without any communication with the external air. Most 160 ANNALS NEW YORK ACADEMY OF SCIENCES of the sciaenoids have a large natatory bladder, very thick, provided with very strong muscles, but the bladder has no communication either with the intestinal canal, or with the exterior generally." This represents all that was actually known up to the time of Cuvier concerning the mechan- ism of the sound-producing organs. It was evidently thought by Cuvier that the air-bladder and attending muscles were of some importance in producing this phenomenon. Somewhat later (1860), Holbrook stated that "frequent examinations of the structure and the arrangement of the air-bladders, as well as obser- vations on the living animal just taken from the water, when the sound is at intervals still continued, have satisfied me that it is made in the air-bladder itself; that the vibrations are produced by the air being forced by strong muscular contraction through a large opening, from one large cavity, that of the air-bladder, to another, that of the cavity of the lateral horn; and if the hands are placed on the sides of the animal, vibrations will be felt in the lateral horn, corresponding wdth each sound." It was not until Dufosse published his memoir on the sounds and noises produced by the fishes of Europe, in 1874, that we had any physiological explanation of the phenomenon in the scisenoid fishes which is based on actual experiments. In 1864, Moreau published the results of his experi- ments on the "grunting" mechanism in the Triglidse, a process, however, which is entirely different from the "drumming" of the Sciaenidfe, and should not be confounded with it. With regard to the sounds produced by certain muscles Dufosse says, Le phenomene physiologique connu generalement sous le nom de trepidation ou tremulation musculaire, et que WoUaston a assimil^, avec raison, a un mouvement de vibration, n'a pour ainsi dire ete observe que chez rHomme, et n'a jamais ete le sujet d'une etude approfondie, soit au point de vue biologique, soit au point de vue la physique proprement dite, quelques physiologistes pensent meme encore que ce mouvement assez rapide pour produire un leger bruit, designe sous le nom de bruit de rotation par Laennec et sous celui de bruit de contraction des muscles par d'autres auteurs, est trop faible par lui-meme et trop peu important par ses effets pour devenir jamais d'un certain interet en physiologie generale. This is a concise statement of what was known concerning the physiology of this noise at the time when Dufosse wrote his memoir. Dufosse divided his work into two propositions, viz: 1. Quelques muscles de certains poissons bruyants deviennent en se contractant susceptibles d'un mouvement de vibration: 2. Ce mouvement est le principe des sons que font entendre ces animaux. To prove these propositions, Dufoss^ made two physiological expcri- TOWER, PRODUCTION OF SOUND IN CERTAIN FISHES 161 ments. In the first, he inserted his finger into the stomach of a lyre capa- ble of producing an intense noise. During the production of the noise, he noticed an intense vibration which coincided exactly in duration -with the sounds heard by his ear. He then punctured the wall of the air-blad- der and drew out all the gas. The sound ceased, but the vibrations could still be felt. He then removed the entire swim-bladder, and applied his finger successively to the muscles and aponeuroses which lie alongside the vertebral column, and he found that all the organs were in repose except the intra-costal muscle, which vibrated and gave to his finger the same sensa- tion as when the air-bladder was in its natural position. In the second experiment, Dufosse opened the abdomen of a lyre just in front of the anus, and extirpated the swim-bladder entirely ("j'extirpe la vessie pneumatique tout entiere"). He then inserted an artificial blad- der ("poche membraneuse") and inflated it. The fish commenced again to produce a noise similar to that made before the operation. In another he cut the nerve supplying the intra-costal muscles, first the right and then the left. After both were cut, the noise ceased and could not be again renewed. From these data, Dufosse argues that there are tv\'o factors in the pro- ducing of the noise, \t1z: the contraction of the intra-costal muscle, which is the primary cause of the sound, and secondarily, the reenforcement of these vibrations of the swim-bladder. The producing of the noise is volun- tary. Dufosse recognizes many difficulties in this explanation, however, because the facts do not agree with those of theoretical physics, as can be seen from the following quotation: — " Le mecanisme de la production des sons chez ces poissons a pour complement la transmission des \abrations sonores des muscles a la vessie qui est en contract avec eux. Les parois de est organe commvmiquent ces vibrations au gaz qu'elle renferme, et ceux-ci ^'ibrent de telle fagon comme le prouvent surabondamment mes deux premieres experiences, que I'intensite de ces vibrations est incomparablement aug- mentee. D' apres ce resultat et en considerant que la vessie est une cavite close a parois membraneuses et souples se raoulant si exactement sur la surface des organes qui les enviromnent qu'elles ne peuvent vibrer que comme elles le feraient si elles ^taient reellement adherentes par tous les points de leur superficie a la masse de ces organes on ne pent expliquer, conformement aux principes dc la physique, le ren- forcement des vibrations sonores qu'en admettant que le volume des gaz contenus dans vessie, ou, ce qui est le meme chose, que la capacite de cet organe a naturelle- ment des rapports exacts de grandeur avec cells des nombres de vibrations sonores que lui sont transmises. L'exactitude des rappoits que suppose cette explication ne s'accordant pas avec plusieurs faits ichthyologiques, entre autres avec les inces- sants changements de volume que submit necessairement la vessie pneumatique quand le poisson vient du fond de I'eau a la surface ou s'enfonce dans la profandeur des mers, cette explication n'est acceptable qu'en admettant que si ces rapports 162 ANNALS NEW YORK ACADEMY OF SCIENCES existent reellement ils doivent pouvoir varier d'une certaine quantite sans que le degre de renforcement des sons soit grandement modifi^." In speaking of the ScisenidEB, Dufosse says that the sound is produced for the most part by muscles; but a little later, in speaking of Psevdo- sciaena aquila, he says " Le mecanisme de la production des sons chez les iudividus de I'espece Scicena aquila est plus compliqu^ que celui des poissons dont j'ai parl6 jusqu' k present (lyre). Je n'ai nullement la pretention de donner la th^orie de ce mecanisme." Just why Dufosse makes this statement is not intelligible, for all the drum- ming fishes of America that have been examined have the same mechanism, and it is very evident that the sound is produced in exactly the same way. As Dufosse examined only European forms, however, he may have ob- served a difference in structure that is not present in the American species. The fact that Dufosse stated that he could not explain the mechanism in Sciosna, while for the Gurnard lyre his exj')lanation was not in accordance Avith physical phenomenon, has possibly led more recent ichthyologists to ignore his work. Thus we find that Giinther (1880) in speaking of the A merican drum {Pogonias cromis) says, "It is still a matter of uncertainty by what means the "Drum" produces sounds. Some naturalists believe that it is caused by the clapping together of the pharyngeal teeth, which are very large molar teeth. However, if it be true that the sounds are accompanied by a tremulous motion of the vessel, it seems more probable that they are produced by the fishes beating their tails against the bottom of the vessel in order to get rid of the parasites with which that part of their body is infested." That these explanations of Giinther are unwarranted will be seen from experiments soon to be described. Sorensen (1895) disagrees with Dufosse s statement that it is the vibra- tion of the muscles while contracted which produce the sound and that the air-bladder only intensifies the sound. Sorensen considers the sound as being produced by vibrations of the air in the air-bladder and of the walls of the latter when set in motion by the muscles with the fascia of which it is connected. Jordan and Evermann (1902) say that "most of the species make a peculiar noise, variously called croaking, grunting, drumming, or snoring, supposed to be produced by forcing air from the air-bladder into one of the lateral horns." We have presented to us then, four distinct mechanisms in the Sciffi- noids : 1. Muscular tone; the vibrating muscle producing a sound which is intensified by the air-bladder (Dufosse). TOWER, PRODUCTION OF SOUND IN CERTAIN FISHES 163 2. Clapping together of pharyngeal teeth (Gunther). 3. Vibrations of air in air-bladder and of the walls of the latter when set in motion by certain muscles (Sorensen). 4. Forcing of air from air-bladder into one of lateral horns (Holbrook, Jordan and Evermann). Experiments to Determine Cause of Sound. That the explanation given by Gunther is wrong can be very easily seen from the following experiments, in all of v/hich the animals were kept alive by artificial respiration, i. e. by irrigating the gills with a stream of fresh water. Experiment I. The air was drawn from the swim-bladder of a squeteague by- means of a trochar and the drumming immediately ceased. a. The stomach was then filled with water. The drumming returned but not as loud as normal. Expenment. II. — An incision one inch long was made in the mid-ventral line. Through this a portion of the air-bladder was pvilled out but the drumming con- tinued. a. The bladder was now amputated and the drumming ceased. b. A collapsed rubber balloon was then inserted into the abdominal cavity, and, as soon as it was inflated, the drumming returned with apparently normal intensity and pitch. c. The rubber balloon was filled with salt water instead of air. The drum- ming continued until the water was allowed to escape; then it ceased. The tone is low and apparently changed but little under the different conditions. Experiment III. — The air-bladder of a male squeteague was removed. The drumming ceased. The air-bladder from a female squeteague, which can produce no noise, was inserted into the abdominal cavity of the male, and the drumming immediately returned. These three experiments show conclusively that the "clapping together of the pharyngeal teeth" has nothing to do with the production of the drumming noise in the squeteague. It is also shown in experiment III that there is no difference between the function of the bladder in the male, which drums, and that of the female, which does not drum, as far as the noise-production is concerned. Experiment IV. — The entire viscera (intestines, spleen, liver, reproductive or- gans and air-bladder) were removed from a male squeteague. The drumming stopped, and the sonificus contracted as usual, but there was no noise. A rubber balloon filled with air was then inserted into the abdominal cavity. The drumming again returned, but was not of normal character. a. The balloon was filled with water and the drumming continued, but was weaker and of apparently different pitch. 164 ANNALS NEW YORK ACADEMY OF SCIENCES This experiment shows that an inflated rubber balloon can take the place of all the abdominal organs in respect to noise-production; although it does not prove that these organs may not play some part in the normal mechanism. To determine whether there is any experimental basis for the view held by Jordan and Evermann, viz: that the drumming is produced by forcing air from the air-bladder into one of the lateral horns, the following experi- ments were undertaken. Experiment V. — An incision about one inch long was made in the mid-ventral line of a male squeteague. The air-bladder was ligatured in the middle, thus sepa- rating the organ into two chambers, — the anterior containing the lateral horns, and the posterior remaining a simple closed ca\'ity. Drumining, however, went on as in nonnal animals. a. The part of the bladder posterior to the ligature was punctured. The drumming continued only in the region of the anterior part of the bladder, which remained inflated. b. Another animal was prepared in the same way, and the part anterior to the ligation was punctured. The drununing continued only in the region of the posterior portion of the bladder, which remained inflated. In this part of the bladder there are no lateral horns. c. The posterior end of the bladder was then folded into the anterior part of the abdomen. The drumming noise then came from the anterior part of the abdomen in the region of the inflated half-bladder. d. The anterior half of the bladder was amputated, leaving the posterior part still inflated. This was inserted at different places and the drumming noise occurred wherever this part of the bladder was placed. Experiment VI. — An incision was made in the mid-ventral line of a large "drummer," about half way between pectoral and anal fins. At the right angles to this incision, longitudinal incisions were made on both sides, extending nearly to the region of the kidney. These incisions were made through the drumming muscles. The air-bladder and -vascera were lifted up with forceps, and the remaining part of the drumming muscle and central tendon was cut. This separated the entire muscle, tendon and insertion into halves — an anterior and a posterior part. The drum- ming still continued on both sides of the bisection. In order to show this still more completely, the anterior half of the abdomen was raised by inserting two fingers, which prevented the drumming in this (anterior) part, while the posterior gave the same characteristic noise. Next, the posterior half of the abdomen was raised in the same maimer, and the drumming stopped in the posterior part but continued in the anterior. Upon removing the fingers, the noise continued as in normal ani- mals. a. The air-bladder was ligatured in the same place as the bisection of the muscle. The drumming occurred as before. Again the anterior and the posterior parts were in turn raised, and the drumming was made to occur in either part at ^nll. The two experiments V and VI, as well as the previous ones, prove conclusively that the lateral horns have nothing to do with producing the TOWER, PRODUCTION OF SOUND IN CERTAIN FISHES 165 drumming noise ; and the forcing of air into the lateral horns, if such takes place, is not the true explanation. It remains now to consider the views of Dufosse and of Sorensen. Is this drumming a muscular tone, i. e., a sound produced by the vibrating muscle and intensified by the air-bladder (Dufosse), or do certain muscles set into vibration the air in the air-bladder and the walls of the latter (Sorensen) ? Experiment VII. — The entire abdominal viscera except the air-bladder were removed. Contractions of the muscles occurred, but no noise. The rubber balloon was inserted into the abdominal cavity and inflated (the air-bladder being intact and inflated). The drumming returned. When the balloon was allowed to collapse, the noise ceased. c. The abdominal ca\'ity was packed tight with cloth (the air-bladder being intact and full of air). The drumming was loud, and when the cut edges were drawn together, it increased to a nonnal di-um. When the cloth packing was removed, the muscle still contracted, but no noise was heard. When the ca\'ity was packed a second time with cloth, the drumming became again audible. Experiment VIII. — The entire viscera, including the air-bladder, were next re- moved. Notwithstanding the large hemorrhage that occurred, the sonifici still contracted. The rubber balloon was inserted and inflated wath air. The drumming noise returned of apparently the same pitch but not so loud as normal. a. The central tendon was then cut longitudinally into two parts. The muscles on either side contracted rhythmically, as could be seen from the vibrations of the cut ends of the tendon. There were, however, no vibrations of the abdominal muscles, such as are seen in normal animals. This was as might be expected, because after cutting the central tendon the two drtimming muscles have nothing to work against. The inflated rubber balloon now produced no sound. This seems to show that the air-bladder does not act as an intensifier of muscular tone. The experiment suggests that the air-bladder functions either in maintaining the tension inside of the abdominal cavity, or as a vibrating organ or both. Experiment IX. — Incisions were made on both sides of the median line of the abdomen. After this operation the drmnming remained perfectly normal. The m. sonifici were then cut from their origin on the abdominal muscles. One side was amputated first, and the drvraiming still continued. While the one on the opposite side was being cut, the drumming died away gradually until the drumming muscle was severed its entire length, when the noise ceased. Yet at this time the muscle contracted, as could be easily felt by touching it with the finger. If now the air-bladder served as an intensifier of the muscular vibrations, Ave might ask why it suddenly ceases to fulfill that function in the above experiment. Also, in experiment II c, drumming occurs when the air- bladder is replaced by a rubber balloon filled with water. This water- bladder cannot be looked upon as an intensifier of sound or a resonator. The foregoing experiments show that any part of the muscle can produce the drumming when conditions are suitable. We have also seen that by 166 ANNALS NEW YORK ACADEMY OF SCIENCES lifting a part of the abdominal muscles, the drumming over that part im- mediately ceases. That the most ventral parts of the abdomen are active in drumming is evident from the vibrations of this part of the body of a squeteague. The whole mid-ventral area, from pectoral fins to anus, pulsates in a strong rhythmical manner, which corresponds to the con- traction of the m. sonificus as can be readily seen from the appended kymo- graph tracings. Experiment X. — An incision one inch long was made about half way between the pectoral fins and the anus and at right angles to the long axis of the body. Great care was taken in order not to injure the drumming muscles. Between the ventral muscles and air-bladder was inserted a piece of sheet cork about two and one-half inches long and two inches wide. This stretched severely the mid-ventral part of the abdominal muscle and held it rigid, so that it could not be pulled in when the sonificus contracted. No noise was produced, yet the muscle apparently contracted in a perfectly normal manner. This would again show that the dnunming is not a muscular tone intensified by the air-bladder. The drumming is undoubtedly a sexual character, for in the squeteague the male only makes this noise. The female not having developed any drumming muscles is not able to produce this sound. In some other scisenoids, as the croaker, both male and female produce the drumming, but the former is said to produce a much more intense noise than the female. I have often observed that the drumming muscles in the male croaker are much thicker and heavier than in the female. The conclusion is that by each contraction of the m. sonificus a sudden blow is dealt which throws into vibration the abdominal walls and organs. The physics of this phenomenon is very complex, as undoubtedly all of the abdominal parts play a r61e. But the organ that chiefly participates in the vibration is the swim-bladder with its walls made tense by the pressure of the contained gas. It is well known that in man the chest walls and abdominal walls can be set into irregular vibration by being percussed and that there is here a resonance effect produced by a resonance cavity or semifluid material which is selectively set in resonance vibration. The gas pressure in the air-bladder as well as the character of the muscular contractions which will be immediately described indicate the same con- clusion. In all of the above experiments the pitch of the drumming sound was not determined with scientific accuracy. Undoubtedly if the tone could have been determined by physical apparatus the pitch, which to the ear was apparently the same, would have been found to be different in the various experiments. TOWER, PRODUCTION OF SOUND IN CERTAIN FISHES lt)7 Experiments to determine character of the muscular contraction. The character of the contraction of the red drumming muscles has never been studied, nor has the relation of the contractions to the pitch of the drumming been accurately recorded. Dufosse has given the pitch of the drumming of the meagre as well as he could determine it by the ear alone. The following experiments were performed in canying on the present study: Experiinent XI. — The first experiment was made so as to record the number of vibrations produced by the abdominal tissue in the mid-ventral line during the process of drumming. To accomplish this, a light wooden lever was made, with a piece of sheet cork two inches long and one half inch wide attached at the bottom, and a fme wire inserted in the top at right angles to the lever. The cork was held in place on the abdomen of the squeteague by two rubber bands going around the fish and over each end of the cork strip. The revohnng drum of the kymograph was then placed so that the wire point would trace on the smoked paper of the drum. Thus when the animal commenced to drum, the vibration of the part of the abdomen under the lever would be traced by the writing point on the smoked paper. The drum of the kymograph revolved once in 4.848 seconds, and its circimaference was 48.5 cm. The tracings are given on PL VIII, fig. 1. The number of vibrations per second, as determined by comparison with the tracings of a tuning fork vibrated 100 times per second, is 24. Exferiment XII. — A control experiment was made the next day on another squeteague, but with the drum of the kjTnograph revohing only once in 20.202 seconds. The number of vibrations should agree or at least be within the limits of experimental error. The tracings are given on PI. VIII, fig. 2. The number of vibrations is again 24 per second. In both of the above experiments the lever Wiis placed on the mid-ventral line just posterior to the pectoral fuis. Experiment XIII. — The next experiment was to determine whether the anterior and posterior ends of the abdomen vibrated synchronously, or whether the \abration passed over the abdomen like a wave, from anterior to posterior, or \dce-versa. Mere observation as well as the resting of the fingers on the anterior and posterior parts at the same time detected that all the muscle-fibres contracted synchronously. To determine this more accurately, two levers were arranged — one being placed just posterior to the pectoral fins, and the other just anterior to the anus — so that they should write under each other on the smoked paper. The traces indicated that the entire abdominal mechanism vibrated synchronously; hence all the fibres of the two drumming muscles contract at the same time under stimuli controlled by the central nervous system of the animal. Experiment XIV. — In a fresh male squeteague an incision one inch long was made on one side through the thick, white abdominal muscles imtil the red m. sonificus was exposed. The cork base of the lever was inserted through this opening until it rested on the red muscle within. With the lever in this position and the 168 ANNALS NEW YORK ACADEMY OF SCIENCES animal on its side., the writing point shoiild not move up and down in a perpendicular plane, but should move horizontally, back and forward. This, then, should give in the kjTnograph reading a series of dots, repre.5enting the apes of each cur\-e. Such a tracing was recorded on the drum of a kj-mograph. The ^■ibrations were 24 per second. From this experiment it is seen that the muscle itself and the abdominal tissue \-ibrate at exactly the same rate. Experiment XV. — Another experiment was made to show the effect of sub- stituting an inflated rubber balloon for the air-bladder. The nimiber of vibrations was 24 per second. It is thus evident that the \-ibrations produced in the presence of the rubber balloon are the same as in the normal condition of the animal. The five preceding experiments agree in the rate of ^■ib^ations of the abdominal part which is in immediate relation to the drumming muscles, and which is directly connected ^vith sound production according to our present views. It vras next necessary to record the contractions of the muscle itself, and for this purpose the following two experiments were performed. Experiment XVI. — An incision two inches long was made in the mid-ventral line just posterior to the pectoral fins. Through this op>ening was inserted a slender v,-ire ■n-ith a sharp hook on one end and an eye on the other. The hook v.-as fastened directly into the fibers of the m. sonificus. The eye was attached to an ordinary muscle-lever which was supplied with a writing point. The kymograph was then placed so that it would receive the tracings made by the -^-riting point. In this experiment none of the \"iscera were disturbed and the noise produced differed in no way from that of the normal animal. To measure the time, a tuning fork was used, whose double vibrations of 100 per second were registered on the revoh-ing drum. The rate of the contractions is 24 per second, which is identical with the experiments made on the abdominal walls. As is shown in PI. 'STII, fig. 3, the ampUtude of the contractions is much more than in the experiments made on the abdominal walls. This is undoubtedly due to the release in tension caused by the separation of the right and left abdominal portions to which these muscles are attached, together with some resistance caused by the rubber bands. To determine this point another experiment was made in which the \"ibrations of the abdominal wall were registerd by a wire hook attached at one end to the rectus abdominis and the other to the muscle-lever. With this method the ampUtude of \-ibration is nearly the same as that of the muscles. It was noticed, too, that when the ampli- tude was the greatest the loudest sound was produced in both the experiments on the abdominal waUs and on the drumming muscle. Experiment XVII. — Experiment X\T was repeated, except that the air-bladder was punctured. The drumming noise stopped. The contractions of the drumming muscles, registered as in the preceding experiment, are given on PI. ^'III, fig. 4. The number of contractions computed from those of a tuning fork is 24 per second. It is veiy- e\ndent that there is no difference between the contractions when the swim-bladder is full of air and when it is collapsed, and that this organ has no effect upon the contractions of the drumming muscle. This TOWER, PRODUCTION OF SOUXD IX CERTAIN FISHES 169 is especially well demonstrated in the tracings where the register of the muscular contractions in an animal with the bladder intact is placed directly over these from an animal in which the bladder is collapsed (PI. VIII, fig. 4). Experiment XVIII. — The viscera, including the swim-bladder, were removed from a squeteague after an incision had been made in the mid-ventral line from the pectoral fins to the anus. The wire hook of the registering apparatus was inserted into the middle of the central tendon. No noise was produced. The number of contractions was 24 per second. The amplitude of vibration was less than some registered by the muscle and more than others. The experiment revealed no new factor. In the experiments just described each contraction of the muscle, repre- sented in the tracing by the apex of the curves, is simultaneous with the sound produced, and thus the rapid series of contractions institute the roll or "drumming." Experiments to determine the pressure of the gas in the swim- bladder. Experiments were made to discover, if possible, the pressure exerted on the air-bladder by the contraction of the drumming muscles. Experiment XIX. — The pressure of gas in the air-bladder of a female squeteague (which has no drumming muscles and can not drum) was determined by making an incision one inch long in the mid-ventral line two inches anterior to the anal fin. The posterior end of the swim-bladder was ligatured and then amputated just back of the ligature. The open end of a small mercurial manometer was inserted and tied by another ligature. The first ligature was then removed and the mercury rose to a height of 4 mm., which was produced by the normal pressure of the gas in the air- bladder. The animal was kept alive by artificial respiration. a. The same experiment was then tried on the swim bladder of a male sque- teague, both while it was quiet and while it was drmnming. In the quiet animal, the pressure rose to 4 nmi. and remained there until drumming occurred, when it rose to 6 mm. In other words, the increased pressure brought about by the contraction of the drumming muscles equalled 2 mm. of mercury. During the di'umming the meniscus of the mercury could be seen to oscillate between 4 mm. and 6 mm., as the muscles successively contracted and then relaxed. One interesting feature is that in all the animals examined the normal pressure in the bladder was 4 mm. in the male and female — the large and small animals alike. The gas pressure within the swim-bladder maintains a tension on the elastic walls, while the increased density of the gas due to the pressure tends to produce a louder sound than would othersvise occur. These experiments show that 170 ANNALS NEW YORK ACADEMY OF SCIENCES 1. The chief cause of the drumming is the contraction of the drumming muscles. 2. As the myogram distinctly shows, the contraction of the drumming muscles is of the nature of a series of simple contractions. 3. These muscles contract at a definite rate, viz.: 24 vibrations per second. 4. By the force of each contraction the abdominal organs are set into vibration, especially the walls of the air-bladder. 5. The elastic walls of the air-bladder are always tense, because of the pressure of the contained gas. This pressure is increased each time the drumming muscles contract. 6. The vibration of the tense walls of the air-bladder and the contained gas are sufficient to produce the drumming noise. 7. The sound produced is low. The actual number of sound vibrations was not determined. Sound production in the Sea-Eobin and the Toadfish. Experiments to Determine Cause of Sound and Character of Mechanism. If a sea-robin is examined under artificial respiration, the single twitch of the abdomen when a grimt is made can be very easily observed. If the animal is opened along the mid-ventral line, both the contraction of the intrinsic muscles and the single twitch of the swim-bladder can be observed. The noise is of the same pitch and loudness after the abdomen has been opened as before. The removal of all the viscera except the air- bladder has no effect on the noise produced. It is noticed that the two muscles contract simultaneously. Experiment XX. — aVn animal under artificial respiration was opened, and various parts of the bladder were stimulated by a current from an induction coil, viz. : a. One of the two nerves suppljnng the bladder was stimulated. A perfectly normal grunt was produced. b. The fibrous part of the bladder was then stimulated. A normal grimt was not produced. c. The muscle itself was stimulated directly. Again a perfectly normal sound was produced. These experiments show only that artificial stimulation of either nerve or muscle will cause a normal sound to be produced. TOWER, PRODUCTION OF SOUND IN CERTAIN FISHES 171 Experiment XXI. — The swim-bladder was removed from a fresh specimen and laid upon the operating table. The nerves and the muscles of the bladder were then stimulated successively as in experiment XX. In each case there was a grunt of the same pitch and intensity as is produced by the normal animal. This shoAvs very clearly that the sound-producing mechanism of the sea-robin is entirely within the bladder and its intrinsic muscles. This mechanism, then, stands in direct contrast to that of the drumfishes, just discussed. Experiment XXII. — The swim-bladder was removed from a sea-robin. The muscle was stimulated and an audible grunt was produced. The bladder was then placed on an improvised registering apparatus, so arranged that the bladder was connected with a muscle lever and writing point. The muscle was then stimulated. An audible grvmt resulted. The vibration of the bladder was registered on the drum of the kymograph. The grunt is produced by one single sharp contraction of the intrinsic muscle (PI. VIII, fig. 6). This was repeated each time that the muscle was stimulated. a. One of the lobes of the bladder was now punctured. Both lobes collapsed. Through the opening was inserted the rubber balloon (collapsed). This was in- flated; the muscle was thus superimposed over the inflated rubber balloon. The muscle was then stimulated as before. It contracted and produced a grunt the same as in the isolated bladder full of air. Moreau (1876) concluded that it was the vibration of the perforated internal septum which was the direct cause of phonation. That this septum vibrates is true, but from the foregoing experiment it would seem that the walls of the air-bladder are the chief Aabrating organ. In the sea-robin the left lobe only possessed the internal septum, but it made no difference with the sound produced whether the right lobe or the left lobe was used for the experiment. b. The uninjured lobe was filled vnth salt water and closed by a ligature. The muscle was then stimulated by a current from an induction coil. A grunt occurred as when the swim-bladder was filled \vith air, although not so loud. These con- tractions were recorded by means of a kymograph and are given on PI. VIII, fig. 7. On comparing the record with those given on PI. VIII, fig. 6, it is evident that the curves have about the same amplitude, but are not so well sustained. Experiment XXIV. — The swim-bladder was removed from a sea-robin as quickly as possible. The muscle was stimulated by a current from an induction coil. An audible grunt resulted. This sound was more intense when the bladder rested on the table. It is interesting to note that this particular animal did not produce any noise while alive. The isolated bladder was then placed on the regis- tering apparatus, and records were obtained under single stimulations and also by stimulations continued for several seconds. The records are given on PI. VIII, fig. 8. The character of the curve is changed by the continued stimulation, the muscles going into incomplete and then complete tetanus. Tetanic contraction does not appear to be the normal procedure, but is produced by artificial stimulation. And as far as could be determined, the sound was produced at the beginning of the tetanus, i. e. at the first up-stroke of the lever, and died out during the remainder of the contraction. The loudest grunts were produced at single full contractions of the intrinsic muscles. The sovmd produced starts with a grunt, which gradually dies out. It does not resemble drumming. 172 ANNALS NEW YORK ACADEMY OF SCIENCES a. The bladder was then punctured and all of the air expelled from both lobes. The muscle was again stimulated, but there was no sound, although the muscle contracted as usual. The collapsed rubber balloon was inserted into one lobe of the bladder, and then inflated. Upon stimulation a grunt was produced. The bladder was now inflated still more, and upon stimulation a grunt of higher pitch was pro- duced. When the bladder was inflated still more, the pitch became yet higher. b. The rubber balloon was now filled with sea-water and the muscles stimulated. A grunt was produced, although the pitch was apparently changed. It is very evident then, that in the sea-robin and the toadfish the swim- bladder with its intrinsic muscle is an organ for the production of sound. By the contraction of the intrinsic muscle the tense walls of the air-bladder are made to vibrate, thus producing the sound. These grunts can be imitated very closely by drawing the forefinger and thumb towards each other over the surface of an inflated rubber balloon, especially if the rubber is dry or has been resined. Conclusions. I. The scisenoid fishes that make a drumming noise have specific sound- producing muscles which are only superficially attached to the swim-bladder. For this drumming muscle the name musculus sonificus has been proposed and adopted. II. The chief cause of the drumming noise is the contraction of the m. sonificus, which produces a vibration of the abdominal walls and organs, especially the swim-bladder. III. The sea-robin and the toadfish, which make a grunting noise, have muscles which are intrinsically connected with the swim-bladder and are known as intrinsic muscles. IV. The cause of the grunting noise is the contraction of the intrinsic muscles which produce a vibration in the walls of the air-bladder. V. The mechanism in the Scisenoidae is adapted to the production of rapidly repeated sounds or rolls. VI. The mechanism in the sea-robin and the toadfish is adapted to the production of sounds repeated at more or less long intervals. TOWER, PRODUCTION OF SOUND IN CERTAIN FISHES 173 Literature Cited.

A comparative study of specimens of the ConvolvulacecB, represerrting the species placed by Linnaeus^ in Ipomcea and Convolvulus, shows that the two groups as there constituted, are far from homogeneous. The type of Convolvulus is Convolvulus major albus, Toumefort, pi. 17 = (Convolvulus sepium L.). The species included in Ipomoaa by Linnaeus do not accord, except in part, with the diagnosis given by him in the Genera Plantarum (1737), where it is stated that the stamens are exserted, and pi. 39 of Toume- fort' is cited. This is Quamoclit Joliis tenuiter incisis & pinnatis (=Ipo- mcea quamoclit L.). Under most circumstances this would establish it as the type of the genus, but it must be remembered that the genus Quamoclit was an accepted and valid genus before Linnaeus called it Ipomcea and the genus has since been restored to generic rank by Moench.^ In the 5th. edition of the Genera Plantarum (1752), the Toumefort reference to pi. 39 is still retained, with the addition of "Voluhilis Dill. Elth. 318." The first species figured by Dillenius under Volubilis is V. zeylanica pes-triginus, pi. 318. f. 4il' (=Ipomosa pes-triginus L.) In deference to historical usage and long continued uniformity, the writer does not believe it necessary to restrict Ipomcea to the group of species typified by Ipomcea quamoclit L., but is inclined to accept the species first figured by Dillinius under Volubilis, if it is necessary to designate a t^-pe for the genus Ipomcea. Without doubt the plant of greatest economic im- portance is Ipomcea batatas (L.) Lam. but as that was placed in Convol- vulus by Linnaeus and was known as Batatas * in pre-Linnaean literature, it has nothing to recommend it as an acceptable type of the genus.

This would cause a most sweeping change of names, which would be neither logical nor conductive to the future stability of its nomenclature. No historical review of the genus will be attempted here, but the cita- tions of species and synonyms is made as complete as possible, with the object of supplying the absence of a bibliography and historical sketch of the genus, and its divisions. The treatment of the genus Ipomcea in the following pages is in many respects similar to that of Choisy,^ Meissner,^ Grisebach,* and Asa Gray.^ The writer includes Batatas Choisy, Pharbitis Choisy, Leptocallis G. Don and Bomhycospermum Presl, in Ipomosa; while the following genera are excluded as worthy of generic rank, Operculina S. Manso, Quamoclit (Toum.) Moench, (incl. Mina Llav. & Lex.), Exo- gonium Choisy, Calonyction Choisy, Turhina Raf. and Rivea Choisy. The writer is under deep obligations, for valuable suggestions and aid, to Dr. N. L. Britton of the N. Y. Botanical Garden; Dr. J. N. Rose and Mr. J. H. Painter of the U. S. National Museum; Dr. B. L. Robinson and staff of the Gray Herbarium of Harvard University.
