S. A. mcmxii r \ •ivww* COltsI V , \ ' - PREFACE. This “Review of the Primates’’ is the result of a casual suggestion of my friend Frank M. Chapman, Esq., that I should “write a book on Monkeys.” The magnitude of the task — to compel all the described forms of the Primates to present themselves in their representatives for critical examination and comparison — was thoroughly appreciated, and also it was equally well understood that no Institution in the world contained a collection of these animals sufficiently large to permit a work like the present to be successfully completed by its aid alone. For over a century the Primates have been a subject of careful study by Naturalists of all lands, some most eminent Zoologists having devoted their investigations to them almost exclusively, and con¬ sequently the types of the many species were scattered throughout the various Museums of the world. To examine and compare these important examples was a necessity, for without a thorough knowledge of their characteristics no satisfactory progress toward the solution of their proper scientific standing could be reached. With representa¬ tives of the Primates, either from the eastern or western hemispheres, the Museums of the United States were but poorly provided, and a reli¬ ance for the material to prosecute the work was therefore to be placed upon the collections contained in European Museums and Zoological Gardens, and also in those of Eastern lands. Consequently the Author was obliged to visit all these various Institutions and study their collections. Twice were the Museums of England and the Continent visited, and many months passed each time examining the collections, and during a journey around the world, the Museums and Gardens of the far East were also visited and their collections care¬ fully studied. The Author has seen and taken a description of nearly all the types of the Primates extant in the world to-day, and there is not a collection of these animals of any importance existing at the present time with which he is not familiar. The results of five years’ continuous study are therefore embodied in this work, and the conclusions given, no matter how they may dis¬ agree at times with the opinions expressed by other laborers in the same field, have in every case been reached only after careful and patient investigation. Even with the collections of the world at one’s service, material in numerous genera is still greatly lacking; and in some of these, iii :o: ■j IV PREFACE whose members are prone to almost indefinite individual variation, it is exceedingly doubtful if material will ever be gathered together sufficient to enable the question, of how many separate forms actually do exist, to be satisfactorily and definitely determined. A number of the types of the earlier describers, as well as some of later date have disappeared, and on account of this misfortune the species they represented cannot be established, and this is especially unfortunate when the name given has, for many years, been adopted and applied to the evidently wrong animal. To correct such errors will probably be a slow process, as it is difficult to overcome a bad habit once formed. Again numerous examples that served for types, by the passing of the many years since they received their names, have so deteriorated — from the accumulation of dust, the loss of their fur, and fading of their colors from unwise exposure to light — as to be no longer recognizable or of any value as the special representative of some particular species, and such cases are particularly to be regretted when the original description was so brief as to convey but a faint idea of the appearance of the animal. The earlier writers seem to have depended mainly for the charac¬ ters of their species on the colors of the pelage and its distribution, and rarely considered the more important characters of the crania. Their limited material gave them no idea of the great variation, mainly individual, that existed in the coloring of the pelage among members of numerous genera, and so were misled into believing their examples represented more than one species, when it was only the individual eccentricities of a very variable form that they were unknowingly considering. Notwithstanding the vast accumulation of examples of the Pri¬ mates from all parts of the world in the last twenty years, a number of important facts cannot yet be settled, nor will they be until much additional material is received. In the recognition of apparently distinct forms, subspecies in only comparatively few cases have been accepted, because intermediates between what are recorded as species have rarely been found in this Order, and neither of two forms, no matter how closely they are evi¬ dently related can properly be deemed a subspecies, no intermediates having been observed. Also the Author has not seen his way to estab¬ lish a subspecies between the dweller of an island and one of the main¬ land, because, no communication being possible, the appearance of intermediates would seem most improbable. Not so however, with the dwellers of contiguous islands which may at one time have been por- PREFACE v tions of a larger island, or where communication between the islands may be, or at an earlier period, has been, possible. Under such condi¬ tions subspecific forms may be found ; but on the mainland where there is no evidence of a gradation from one form to another, sub¬ species may not be accepted. The Author has dwelt upon this point, because it may occasion surprise to some who examine these volumes, to find how few sub¬ species comparatively have been accepted, and it seemed best to explain how these are regarded, and what, as the Author conceives it, is the only method by which they can be produced. In the present work there are altogether fifty-five complete monographs, with about six hundred species, for it was deemed best that every genus should be treated monographically. Of course these vary greatly in importance and in the number of their species, from one only, to over eighty, but the average would be about twelve to a genus. Each member of the Order has been treated after the following method. First a general review is held of the genus accepted, the type fixed and description given ; then remarks are made on the appearance and general habits of the species the genus contains, followed by a review of the literature and the geographical distribution, and a key by means of which it is possible that all the species of that particular genus may be recognized. Then each species is taken up in regular sequence, its synonymy given and the type locality and geographical distribution recorded ; the present location of the type if existing, is then told, after which the peculiar characters of the species if it possesses any, are given, followed by such remarks as may be necessary, upon the relationship the species under review may have with some other in the genus; then a full description and measurements of the type if possible, concluding with an account of the habits so far as they may be unquestionably known. Of course it is not to be expected that a work such as this can be produced solely by the unaided efforts of one individual no matter how long or conscientiously he may labor, and many times he is obliged to rely upon the aid of his colleagues as the work progresses. Con¬ sequently during the past five years the Author has been assisted in many ways by a large number of his scientific friends. And here he may be permitted to express the great pleasure and gratification he felt at the universal courtesy and kindness he received at all the great Museums in Europe and the East, as well as in those of his own land, by the officers who had charge of the great collections. Every possible facility was given him and unrestricted access to the collections at all times ; and wherever the Author went, his simple request proved to be vi PREFACE an ‘open sesame’ to the treasures he desired to see, and everything was done to forward his investigations and make his visit profitable as well as agreeable. Among the large number therefore to whom the Author feels especially indebted beginning in his own land, he would first mention his distinguished friend, Professor Henry Fairfield Osborn, LL.D., D.Sc., Sc.D., etc., President of the American Museum of Natural History, who from the beginning has taken a deep interest in this work, and through whose efforts solely its publication in the present attractive form has been made possible. The Author desires there¬ fore to express his lively appreciation of a scientific colleague’s aid in making accessible to mammalogists throughout the world a contri¬ bution, the result of much weary labor, towards the elucidation of the members of the most important Order in the Animal Kingdom. To Dr. J. A. Allen, Curator of Mammalogy and Ornithology, and Dr. W. K. Gregory, Assistant in Vertebrate Paleontology in the American Museum of Natural History, New York, the Author is indebted ; especially to Dr. W. K. Gregory who gave the most careful supervision to the publication of the work, as well as to the illustra¬ tions that so much enhance the value of the volumes, a labor that was by no means slight nor free from various difficulties. To Witmer Stone, Esq., Curator of Ornithology in the Philadelphia Academy of Natural Sciences ; to G. S. Miller, Esq., Assistant Curator Department of Mammals, and N. Hollister, Esq., Assistant in the same Department of the United States National Museum the Author is under many obli¬ gations. And finally his thanks are due to F. J. V. Skiff, Esq., Director of the Field Museum of Natural History, Chicago, for the loan of skulls from that Institution. In England he would express his great obligation to Oldfield Thomas, Esq., Head of the Department of Mammals in the British Museum, where the collection of the Primates, regarding it in a general sense, is probably the finest and most complete in the world, the Author was permitted to work as if it were his personal property, Mr. Thomas only insisting that all novelties discovered should be described by the Author, and not as would naturally be expected, by the Head of the Department. Also to Guy Dollman, Esq., Assistant in Mammalogy in the same Institution, who aided the writer in many ways, and whose intimate knowledge of the collection and especially the location of the specimens by which much time was saved, was of the greatest advantage. Also to R. Lydekker, Esq., who permitted the removal from the cases of many mounted specimens, all of which were in his PREFACE vii keeping. In Paris, Monsieur le Docteur E. L. Trouessart, in whose charge is the magnificent collection of Mammals in the National Museum of the Jardin des Plantes, assisted the Author by every means in his power, and placed at his disposal that wonderful collection of the Primates which contains so many of the types of the old Authors, an intimate knowledge of which is necessary for the determination of the species they represent. In the great Museum at Leyden, Holland, so rich in specimens of the Lemuroidea and examples of other Pri¬ mates from the islands of the Eastern Archipelago, the Director, Dr. F. A. Jentink, and in his absence Administrator Vesteroon Wulver- horst made the Author’s labors in the Institution easy and pleasant. In Berlin, Herr Paul Matschie, Curator of Mammalogy, placed the grand collection of Primates so rich in examples of African species especially of Chimpanzees, Gorillas, Guenons, (Lasiopyga) and Colo- bus or Guerezas, at the Author’s service, and aided him in every way possible. Also to Herr O. Neumann for information concerning the new species of monkeys obtained by him in East Africa and which were deposited in the Museum. The collection of Chimpanzees in this Institution is the largest in the world, and exhibits the wonderful indi¬ vidual variation that exists in the skulls and coloring of the skins of these apes ; variations that serve more to perplex than to enlighten the observer on the mystery of species, and what really constitutes such a rank. In Dresden the Author’s thanks are due to Dr. A. Jacobi, the Director of the Museum, who aided him in becoming familiar with certain important types in the collection under his charge; and in the splendid Museum in Vienna, to the Director Dr. F. Steindachner, and custodian Dr. L. R. Lorenz, the Author is greatly indebted for many attentions and assistance in examining the collection which comprises the examples procured by Natterer during his sojourn in Brazil, as well as important specimens of the Gorilla procured by Du Chaillu in the Gaboon, West Africa. To Professor Dr. R. Hertwig, Director; Dr. W. Leizewitz and Dr. C. Hellmayer, Custodians of the Zoological Museum, Munich, in the collection of which are contained Spix’s types, and a very large number of examples of the crania of Bornean Ourangs obtained by Selenka, the Author is under many obligations for their courtesy dur¬ ing his sojourn in their city. In Frankfort-on-the-Main, by the cour¬ tesy of the Acting Director, Dr. Drevermann of the Senckenbergian Museum, the Author was enabled to examine the skins and skeletons of Pseudogorilla mayema? which, from the disappearance of the type, are the only specimens known in Europe at the present time. PREFACE viii In Calcutta, Dr. N. Annandale, the Superintendent of the Natural History Section of the Indian Museum, unfortunately was absent in Burma, but access to the collections was afforded, and every facility for inspecting the types of Blyth and other of the earlier Indian Naturalists, which still survived. In the various Zoological Gardens of Europe and the East many interesting and valuable species were seen, and in the Zoological Gardens at Antwerp was discovered the handsome Monkey which the Director, M. l’Hoest, kindly permitted the Author to describe under the name of C. insignis. In the Gardens at Cairo, Egypt, under the pilotage of his friend Captain Flower, the Director, several specimens of the rare monkeys of the genus Erythrocebus were shown to the writer and descriptions taken. It was the skins of these same animals that, some eighteen months later in the British Museum, served the Author as the types for two new species. In the Calcutta Gardens were some fine examples of Hylo- bates hoolock and the Author’s ears were deafened by their powerful voices ; and also a splendid specimen of the somewhat rare Pithecus andamanensis was seen ; and in the Zoological Gardens of Kyoto, Japan, were numerous living examples of the peculiar Japanese species P. fuscatus, and one very fine adult male Magus ochreatus. The Author also desires to express his thanks to Mr. R. I. Pocock, Super¬ intendent of the Gardens of the Zoological Society in Regent’s Park, London, for his assistance in examining the Primates under his charge. As it was not possible to assemble in one locality all the material it was desirable to employ for ilustrating the work, photographs of the crania had to be taken in different places. Those of the crania of Pseudogorilla mayema? were most kindly sent to the Author by Dr. O. zur Strassen, Director of the Senckenbergian Museum at Frankfort-on-the-Main ; those of the Ourang crania were executed at the Zoological Museum in Munich ; those of Gorilla gorilla, G. g. jacobi and G. g. matschie, from the crania in the Berlin Museum. A certain number were also obtained from the American Museum of Natural History, the United States National Museum, the Field Mu¬ seum of Natural History, Chicago, the Philadelphia Academy of Sciences, and especially the British Museum. The Author cannot refrain from calling attention to the illustra¬ tions produced by the methods and greatly improved instruments invented by the Special Photographer of the American Museum, Mr. Abram E. Anderson, which for clearness and perfection of detail, have possibly not been heretofore equalled. Mr. Anderson was sent to London expressly to photograph the crania in the British Museum, PREFACE IX and the illustrations given in the plates exhibit faithfully the particular characteristics of the genera and subgenera. Those skulls which are lacking are fortunately very few. The colored illustrations have been selected from those published in the Proceedings of the Zoological Society of London, chiefly by the great artist, my friend the late Joseph Wolf, and, through the kindness of the Council of the Society, it is permitted to reproduce them in this work. Those of the different species from life were taken by Mr. Lewis Medland, F.Z.S., of London, and certain excellent figures taken by Mr. E. L. Sanborn from animals living in the menagerie of the New York Zoological Society, and presented by the Trustees for this work. Measurements of the Primates, such as those confined to the dimensions of the skin removed from the body, are of comparatively little value as there is probably considerable difference in size between the average stuffed specimen and the living animal. But those given of the crania are reliable and important, and not subject to variation after the death of their owners. Body measurements in these volumes, unless followed by (Collector), are taken from the dried skins, and are always given in millimetres. Those of the hands and feet, as the skin of these members usually contains the bones, are reliable for length, but the figures given for dimensions of the body and tail can, in the majority of cases, only be regarded as approximate. Mammals, unlike birds, vary greatly in their dimensions even among examples of the same species, and therefore, equal importance, when taken from the skin, cannot be attached to them. When a species in this work is mentioned, the name adopted is printed in capital letters, but in italics for subspecies and synoptical names. Measurements are always given in millimetres. All the species and races known to the Author that have been described prior to June 1st, 1912, are included in the three volumes. After the date mentioned, the advanced state of the press work did not permit of any additions, except in an Appendix to the third volume. June 1st, 1912. D. G. E. . . ’ . >•» * INTRODUCTION. I he Primates, which is the first of the Linnsean Orders of the Mammalia, was originally composed of four genera Homo, Simia, Lemur and Vespertilio, Man, Monkeys, Lemurs and Bats. The last has been dropped by general consent, and the Order as now con¬ stituted combines the Bimana and Quadrumana. Some Naturalists have contended that the Lemurs should be placed in a separate Order, and my friend the late Prof. A. Milne- Edwards enumerates the following characters as justifying this view: The bell-shaped, diffused and non-deciduate placenta, vast size of the allantois, uncovered condition of the cerebellum, cranial structure, inferior incisors, and structure of the extremities, (developed pollux, and discoidal terminations of the fingers). While admitting the importance of these characters, *St. George Mivart has made some critical remarks regarding the decision of Prof. A. Milne-Edwards, and fairly well establishes the fact that the better course would be to leave the Lemuroidea as a Suborder of the Pri¬ mates as “there can be no doubt that Man-Apes, (including Baboons and Monkeys), and Half-Apes together constitute a group capable of convenient and very distinct Zoological definition,” and he defines the group as follows : “Unguiculate, claviculate placental mammals, with orbits encircled by bone; three kinds of teeth, at least at one time of life ; brain always with a posterior lobe and calcarine fissure ; the inner¬ most digits of at least one pair of extremities opposable ; hallux with a dat nail or none; a well-developed ccecum; penis pendulous; testes scrotal; always two pectoral mammce.” The Order Primates then comprises two Suborders Lemuroidea and Anthropoidea. The first contains the singular nocturnal animals known as Lemurs which are distinguished from the members of the other Suborder by the following characters : Orbit opening into the temporal fossa beneath the postorbital bar, (Tarsius excepted). The lachrymal foramen situated outside the orbital margin. The second digit of the hand may be merely a rudi¬ ment, but the same digit of the foot has a long pointed claw. The cerebrum does not overlap the cerebellum, and the hemispheres have *Proc. Zool. Soc. Lond., 1873, p. 504. XI INTRODUCTION xii few convolutions. Posterior cornu of lateral ventricle very small; pollux large ; posterior cornu of hyoid shorter than anterior , clitoris perforated by the urethra; uterus two-horned; placenta bell-shaped, diffused, non-deciduate ; allantois very large; transverse portion of colon convoluted on itself. Abdominal mammae sometimes present. The Lemuroidea contains three Families, the first two aberrant; DaubentoniiDyE with its single species the curious Aye-Aye, and Tarsiid.e, for a long time supposed to have also a single species, but several additional ones have been lately recognized. The third Family is NycticibiDyE with four Subfamilies, LorisiNyE, the Slow Lemurs with four genera : Loris with two species ; Nycticebus with eleven species ; Arctocebus with two species ; and Perodicticus with five species. The last genus, Perodicticus, for over two hundred years was represented by only one species, Bosman’s Potto, discovered by that traveller in 1705; but within a brief period no less than four others have been described, showing how easy it is to overlook distinct forms among these nocturnal animals, even though their habitats had been often penetrated by zealous Naturalists eager to make known the creatures that had heretofore escaped all research. In this same Sub¬ family is the genus Arctocebus with its single species from Old Calabar, remarkable for its strongly flexed fingers, which require considerable force to extend them, and when this is taken away they at once become flexed again. The second Subfamily is GalagiNyE, the Bush Babys, with one genus and twenty-three species and six sub¬ species, followed by LemuriNyE, the true Lemurs, with seven genera and thirty-eight species. The last Subfamily is Indrisin.e with three genera including the Woolly Lemur, Safakas, and Indris, having in all five species and five subspecies. While Madagascar alone possesses the Aye-Aye and the species of the Subfamilies LemuriNyE and IndrisiNyE, none of those con¬ tained in G.\lagiNyE are found on that island but belong to the near-by African Continent. The Tarsier are natives of the islands of the Indo- Malayan Archipelago and the Philippines, while the Slow Lemurs (LorisiNyE) are met with in the southern part of the Indian Peninsula and the Island of Ceylon. The second Suborder, ANTHROPOIDEA, is distinguished from LEMUROIDEA by its members having the orbit separated from the temporal fossa by a bone which is united to the postorbital bar; and the lachrymal foramen is inside the orbital margin. The second digit of the hand is well developed, and the same digit of the foot has usually a flat nail, except in Callitrichid.e. The cerebrum almost completely INTRODUCTION xiii covers the cerebellum, and the hemispheres are considerably con¬ voluted. Placenta deciduate, discoidal. Allantois small, uterus not two-horned, anterior cornu of the hyoid shorter than the posterior, no abdominal mammae present, and the transverse portion of the colon not convoluted. This great Suborder, containing, as it does, all the existing Apes, Baboons and Monkeys, is divided into two groups: 1st, the Platyr- rhine, those species having the nose flat, septum wide and the nostrils directed outward, and embracing all the Monkeys of the New World; and 2nd, the Cratarrhine, having the nose narrow, nostrils directed downward and the septum narrow, including all the species of the Old World. As may well be imagined the variations in size to be witnessed among the members of this Suborder are very great, the extremes being the Gorilla and the small, delicate Marmoset or Titi. And with the difference in size, there is also great variety in the shape of head and body, and length of limbs and tail. This last appendage is entirely absent in the great Apes of the Families Hylobatid^: and Pongihxe; is of varying length from a mere knob, to longer than head and body in Pithecus ; much longer than head and body in many species of Lasiopyga and Pygathrix, and nearly three times the body’s length in Ateleus. The heads of the Primates also are remarkable for their many shapes from the round head of Ateleus, the occipital protruding skull of Saimiri, the almost human braincase of Pan, to the narrow high-crested crania of Gorilla and Pongo. The rostrum also exhibits many shapes producing conspicuous differences in the physiognomy of the many species, the extremes perhaps being the nearly flat-faced members of the Cebid.e and the greatly lengthened muzzle of many of the Baboons as P. cynocephalus and P. sphinx, the latter exhibiting a rostrum covered with prominent ridges, and decorated with brilliant and highly contrasted colors. Many of the Lasiopygid^: have ischiatic callosities, some brilliantly colored, and these at certain seasons become enormously developed covering not only the buttocks, but also extend¬ ing on to the tail which is greatly swollen. However attractive this may be to Baboons, to human eyes such exhibitions are repellent. The nose, save in one exceptional case, is not a very prominent member among the Primates, although, as in Man, it has many shapes, from the aquiline in Hylobates, most pronounced in H. hoolock, the retrousse nose of Rhinopithecus, and the extraordinarily lengthened member of Nasalis. The limbs of the Primates show great diversity when compared between distinct species, or between the fore and hind limbs XIV INTRODUCTION of one individual. Thus we have the rather short stout limbs of equal length in Pithecus, the lengthened slender limbs of Ateleus, the long arms and short legs of Hylobates and Symphalangus, and carried to an extreme, considering thd difference in size, in Pongo, where arms and hands reach nearly to the ankles when the animal is in an erect position. All kinds of texture characterize the pelage of the Primates, from velvety softness to one that is coarse and harsh. The hair assumes various arrangements, sometimes forming coronal or occipital crests, occasionally both, or fringing the face with obtrusive whiskers, or projecting over the forehead like the peak of a cap. Long curled moustaches are rarely present, as in a species of Leontocebus, exhibiting a remarkable growth. In many species the hair of the head is short and compact, sometimes with horn-like erections over the forehead, or on the sides of the head as in Cebus, while in one species Pithecus albibarbatus, the entire face is surrounded and the head covered by long hair in the semblance of a huge wig. On the body the hair is often long over the shoulders forming a mantle, and in other cases falls from the sides or over the rump in long graceful fringes as in most of the black species of Colobus. The tail as a rule is covered by short hair, but the end is sometimes tufted as in Rhino- pithecus and Colobus, and these tufts or tassels in some species of the last genus are greatly enlarged, equal in one species to one third the length of the tail. Only one species has a bare tail with end tufted Simias concolor, an extraordinary animal. All colors are shown in the different pelages many of vivid and contrasting hues, and while some one member of nearly all the genera has bright coloring, probably Lasiopyga, embracing as it does such a large number of species, con¬ tains more highly colored members than any other genus of the Pri¬ mates. Beards are not infrequently met with, in fact in Alouatta this appendage to the face of the species is rather characteristic of the genus; and in all the Families, save Pongiid.e, the hairs of the arms are directed towards the wrist, but in the members of that Family the hairs of arm and forearm grow in opposite directions the first down¬ ward and the latter upward meeting at the elbow, and as it is supposed these great Apes usually sit with their arms crossed, Darwin imagined that this peculiar arrangement of the hair was to permit the rain to run off at the elbow. Ears of the Primates are well developed and pointed, but the lobe is absent, the Gorilla alone having it present in a rudimentary condition. The voice of the Apes is described in the Gorilla as a roar, but in the Chimpanzee as a gruff bark-like tone. INTRODUCTION xv Some of the small Monkeys of the New World emit a whistling note, often plaintive, but the most wonderful voices are those possessed by the species of Alouatta in South America, and of Hylobates of the eastern hemisphere. In these the throat is large and thick and the larynx greatly developed. The basihyal is much enlarged and is ex¬ panded into a bony capsule which is lined by a continuation of the thyroid sac, and this peculiar formation enables the animal to produce a volume of sound that can be carried, it has been estimated, for a distance of three miles. The brain of the great Apes is slightly more than half the size of that of Man. The Gorilla, like all of the Quadrumana, has the brain fully developed before the permanent set of teeth are completed. At that period the animal has not, of course, its full stature, and the skull continues to grow with the animal, but the brain does not, the skull becoming heavier and thicker in bone with broader and longer crest, but the brain itself is stationary. *“The relative size of the brain varies inversely with the size of the whole body, but this is the case with warm-blooded vertebrates generally. The extreme length of the cerebrum never exceeds, as it does in Man, two and a quarter times the length of the basi-cranial axis. The proportions borne by the brain to its nerves are less in the Apes than in Man as also is that borne by the cerebrum to the cerebellum. In general structure and form the brain of Apes greatly resembles that of Man. Each half of the cerebrum contains a tri-radiate lateral ventricle, and though in some Lasiopygim: the posterior cornu is relatively shorter than in Man, it again becomes elongated in the Cebim:, and in many of the latter it is actually longer relatively than it is in Man. The posterior lobes of the cerebrum are almost always so much developed as to cover over the cerebellum, the only exceptions being the strangely different forms Mycetes, (Alouatta), and Hylobates, (Symphalangus), syndac- tylus. In the latter the cerebellum is slightly uncovered, but it is so considerably in the former. In Chrysothrix, (Saimiri), the posterior lobes are much more largely developed relatively than they are in Man. The cerebrum has almost always a convoluted external surface. In this group, however, as in mammals generally, a much convoluted cerebrum is correlated with a considerable absolute bulk of body. Thus in Hapcile, (Callithrix), (and there only), we find the cere¬ brum quite smooth, the only groove being that which represents the Sylvian fissure. In Siinici, (Pongo), and Gorilla, and Anthropo- *St. George Mivart, Encycl. Britan., 9th Ed, Article Ape. XVI INTRODUCTION pithecus, (Pan), on the contrary, it is very richly convoluted. A hippocampus minor is present in all Apes, and in some of the Cebid.® it is much larger relatively than it is in Man, and is absolutely larger than the hippocampus major. Of all Apes the Ourang has a brain which is most like that of Man; indeed it may be said to be like Man’s in all respects, save that it is much inferior in size and weight, and that the cerebrum is more symmetrically convoluted and less com¬ plicated with secondary and tertiary convolutions. If the brain of Simia, (Pongo), be compared with that of Gorilla, and Anthropo- pithecus, (Pan), we find the height of the cerebrum in front greater in proportion in the former than in the latter ; also the bridging convolutions, though small, are still distinguishable, while they are absent in the Chimpanzee. Nevertheless the character cannot be of much importance since it reappears in Ateles, ( !) while two kinds of the genus Cebus (so closely allied as to have been sometimes treated as one species) differ strangely from each other in this respect. The corpus callosum in Apes generally, does not extend so far back as in Man, and it is very short in Pithecia. In the Ourang and Chim¬ panzee there are, as in Man, two corpora albicantia, while in the lower Monkeys there is but one. The vermis of the cerebellum gives off a small lobule, which is received into a special fossa of the petrous bone. Certain prominences of the medulla oblongata, termed corpora trapezoidea, which are found in the lower mammals, begin to make their appearance in the Cebidie.” The number of pairs of ribs varies considerably among the genera of the Primates. The Gorilla and Pan have thirteen; the Ourang twelve same as Man; Hylobates thirteen, but sometimes sixteen (Flower and Lydekker) ; Colobus twelve; Pygathrix and Cercoce- bus twelve, sometimes thirteen ; Lasiopyga and Erythrocebus twelve ; Pithecus twelve, sometimes thirteen, (P. nemestrinus) ; Papio thir¬ teen; Cynopithecus twelve; Magus twelve; Alouatta, Lago- tpirix, and Ateleus fourteen; Cebus fourteen, but last pair very short almost rudimentary in some species ; Pithecia twelve and thir¬ teen (P. chiropotes) ; Calli cebus and Callithrix twelve or thirteen ; Aotus fourteen; Saimiri thirteen; Nycticebus sixteen; Perodicticus fifteen. Of the vertebrae Pan, Pongo and Gorilla have 4 lumbar, 3 sacral, and 5 caudal ; Hylobates has 5 lumbar ; Colobus 7 lumbar, 3 sacral and 28 caudal ; Pygathrix 6 and 7 lumbar and 3 sacral ; Lasi¬ opyga 6 and 7 lumbar, 3 sacral, 26 caudal ; Pithecus, Magus and Cynopithecus 7 lumbar and 3 sacral, while Magus has 8 caudal, and Cynopithecus has 5 ; Papio 6 lumbar and 3 sacral ; Alouatta INTRODUCTION XVII 5 lumbar, while Lagothrix and Ateleus have but 4; Cebus has 5 and 6 lumbar, while Aotus has 8, and 24 caudal ; Pithecia 6 lumbar ; Callicebus and Saimiri 7 lumbar, the last genus with 28 to 30 caudal ; Callithrix has 6 and 7 lumbar, and 27 to 33 caudal ; Nycticebus 6 and 8 lumbar, and 8 and 11 caudal, and Perodicticus 7 lumbar and 20 caudal vertebrae. The Apes and Monkeys of the eastern hemisphere have thirty-two teeth, the same as in Man, but the Primates of the western hemisphere, excepting those of the F amily Callitrichidaj which also have thirty- two, have thirty-six, the excess being two pairs of premolars, one pair each in the upper and lower jaws. The canines in the males of all Primates are large and extend beyond the tooth rows, and are separated from the incisors by a diastema. The ANTHROPOIDEA have been divided by Authors into five Families, Callitrichims, (usually designated as Hapalidce), Cebida-, Cere opithecidce, (Lasiopygim:), Simiidce (Pongihue of this work) and Homonidce. To these in the present work has been added Hylo- b at hue comprising the Gibbons, which on account of their structure and mode of life seem more properly separated from, than united with, the great Apes. The Gibbons are the only Apes that habitually walk in an upright posture. The Monkeys of the New World, excepting those of the genus Cacajao, differ from all others, besides the number of the teeth in having more or less prehensile tails, this member being frequently bare beneath for a greater or less space at the tip, forming a grasping surface and preventing slipping; and the members of the genus Ateleus are so expert with this organ as to make it serve the purpose of a fifth hand, not only for holding on to the limbs of trees, even suspending the animal without any other support, but often for con¬ veying food to the mouth. Members of other genera, as Brachy- teleus, Alouatta, Lagothrix, Cebus, etc., are provided with pre¬ hensile tails but not all have a bare surface beneath at the tip, consequently the grasp is much less firm and secure, and their dexterity in the use of this organ much less. The species of Cacajao have very short tails of no use to their owners either to assist them in their various movements, or for adornment. There is much difference in size among the American Monkeys from the small Squirrel Monkey (Saimiri) and the Douroucouli (Aotus), to the Howlers (Alouatta) the largest species in the New World. These last are remarkable for the great development of the mandible especially of the angle and ascending ramus, particularly xviii INTRODUCTION noticeable in the male, and is designed to protect and enclose the vocal organs which are of very great size. The shape of body and the manner in which the limbs are pro¬ portioned to it, vary to a considerable degree in these American Monkeys, and it would be difficult to find a greater contrast than the slender, slim-waisted body, and long, attenuated limbs of Ateleus covered with smooth straight hair, and the thick-set, robust body, moderately long, stout limbs, and woolly coat of Alouatta. The genus with the largest number of species in the New World is Cebus containing the well known Capuchin Monkeys, remarkable for their restless, mischievous dispositions, and the wonderful diversity they exhibit in the coloring of their coats. No American Monkey possesses either cheek pouches or callosities, nor is the external auditory meatus ever present. The species of the Cratarrhine group are very different in appear¬ ance from the Monkeys of the New World. The limbs are sometimes of equal length, but generally the legs are longer than the arms except in the great Apes whose arms are invariably longer than the legs. The thumb when present is opposable to the fingers, as is also the great toe to the digits of the foot, and is always shorter than the other toes. The tails vary in length from a mere knob to one exceeding the head and body. Many of the species possess cheek pouches, and callosities are also present in many, sometimes of large dimensions and colored with the most brilliant hues. The Family Lasiopygid^e, to which precedence is given in the arrangement of the Suborder, contains the Baboon, Guenons, Langurs, Guerezas, etc., in fact all the Old World species of ANTHROPOIDEA except the Man-like Apes of the Families Pongiim: and FIylobathxe. The Baboons, which come first in the arrangement of the Families are, besides other physical traits, characterized by an elongate muzzle, which in one species at least is decorated by brilliant coloring, (P. sphinx Linn.). The limbs are nearly equal, but the tails are very variable in length and in the density of their hairy covering. The canine teeth are very long, in some cases prodigiously so, and capable of inflicting a wound as serious as that of almost any dagger. The cheek pouches, in all species that have them, are constructed of folds of skin which expand when food is forced into them, contracting again when emptied and then giving no indication of their presence. These pouches, being placed on the outer side of the jaw, are no hindrance INTRODUCTION xix to the mastication of any food, and are employed mainly for the storage of such edibles as the animal does not desire to consume at the moment. These receptacles even when full are no obstruction to the voice. Besides these pouches large air sacs are present in the neck. The species of the two genera Magus and Cynopithecus, although ranged among the Baboons are generally known as Apes, probably on account of the practical absence of a tail, resembling, as they do, in this respect, the great Man-like Apes. The coat of the Baboon varies considerably in texture from short silk-like hairs to almost a woolly fur observed in those inhabiting a cold clime. The Mangabeys of the genus Cerco- cebus, in some respects, are intermediate between the true Baboons (Papio), and the Guenons (Pygathrix). They have no laryngeal sacs, but possess the posterior fifth cusp in the last molar of each lower jaw. Their form is more slender than that of the Baboons, resembling the Guenons’, and like them they have long tails, but the often brilliant coloring of the Guenon is not seen in the coat of the Mangabey. The genus Rhinostigma contains but one species remarkable for its peculiar physiognomy; the long white stripe from the forehead over the nose to the upper lip, and the presence of a fifth posterior cusp on each of the last lower molars, cause it to be a link between the Man¬ gabeys and Guenons. The Guenons are the most numerous in species of any of the groups belonging to the Lasiopygim:, are more slender in form than the Mangabeys, have not the last cusp on the posterior lower molar, and possess coats of many colors some with strongly contrasting hues, and long tails. Miopithecus has two species the smallest of the Guenons, and Erythrocebus follows with a dozen species, long- legged and frequenters of the plains, rarely sojourning in forests. The Langurs, Pygathrix, placed in a separate subfamily, are also of a slender form with the legs longer than the arms, very long tail, cheek pouches absent, and a sacculated stomach of great complexity. *Sir William Flower has described this organ as follows: “An ordinary stomach must be supposed to be immensely elongated and gradually tapering from the cardiac end to a very prolonged pyloric extremity. Then two longitudinal muscular bands, corresponding in situation to the greater and lesser curvature of an ordinary stomach the former commencing just below the fundus, and the latter at the cardiac orifice, and both proceeding toward the pylorus are developed so as to pucker up the cavity into a number of pouches, exactly on the same principle as the human colon is puckered up by its three longitudinal *Animals Living and Extinct, p. 725. XX INTRODUCTION bands. These pouches are largest and most strongly marked at the oesophageal end, and becoming less and less distinct, quite cease several inches before the pylorus is reached, the last part of the organ being a simple, smooth-walled tube. The fundus or cardiac end of the stomach is formed by a single large sac, slightly constricted on its under surface by the prolongation of the inferior longitudinal band, or that corresponding to the great curvature. The oesophagus enters into the upper part of the left, or pyloric end of this sac, or rather at the point of junction between it and the second (also a very large) sacculus. Furthermore the whole of this elongated sacculated organ is, by the brevity, as it were of the long curvature, coiled upon itself in an irregular spiral manner, so that when in situ the pylorus comes to be placed very near the oesophageal entrance.” The Proboscis Monkey (Nasalis) is unique in one respect, the nose elongate to such a degree as to make it appear a caricature, other¬ wise the animal resembles in form the Langurs. The Guerezas, (Col- obus), are chiefly noted for the rudimentary condition of the pollux or its absence altogether; the long hairs falling as a fringe along the side or over the back, and the long tails usually with a conspicuous tuft. The species of Rhinopithecus and Simias are noted for the diminutive nose turned up at the tip. The Hylobatim: or Gibbons possess a skull not produced at the vertex, long arms with the hands reaching to the ground when the animal stands erect, short legs and small ischial callosities. The species of the genus Symfhalangus differ from those of Hylobates in having the second and third digits of the foot united by webs as far as the last joint. The great Apes form the family Pongiim:, and have the skull produced at the vertex in Pongo, but not in Gorilla or Pan. Ischial callosities are absent ; arms longer than legs ; hands reaching to the ankles in the Ourang when the animal is erect, only to the knees in the Gorillas and Chimpanzees. Upright bony crests are never seen on the crania of the last named, but the other two have frequently con¬ spicuously large bony crests in adult males. The Ourang possesses an os centrali but this, as in Man, is absent in the other two genera. As in the rest of the ANTHROPOIDEA the skull of the male can always be recognized by the elongate canines. When walking, the Gorillas and Chimpanzees go on the knuckles of the hands and the soles of the feet; but the Ourangs proceed chiefly by swinging from tree to tree by the assistance of their long arms. INTRODUCTION xxi CLASSIFICATION. The Order Primates containing, as it does, Man and the creatures which are nearest allied to him, must be regarded as the most important of all those recognized as belonging to the Animal Kingdom'. The various species contained within it, from Man to Marmoset, form a fairly homogeneous group, with which the Lemuroids are associated in a subordinal division. It is a moot point with some whether the Lemurs should be considered members of the Order, having any rank whatever within it, as about the only claim they have to the position is the possession of the opposable great toe, which however is also found in a species of an altogether different Order, the Opossum of the Car¬ nivores. But, no matter how slight may be the pretensions of the Lemurs for admission to the ranks of the Primates, yet, by the almost general acquiescence of Mammalogists, they have of late been accepted as occupying a recognizable place in the Order. The Lemuroids are divided into three Families with four Sub¬ families, having twenty genera and subgenera embracing one hundred and six species forming the Suborder Lemuroidea. The remaining Primates are separated into two divisions containing respectively the Old World and New World Species, designated as the Cratarrhine and Platarrhine. The first, in this work is divided into three Families with two Subfamilies containing twenty-two genera, and about 320 species; the second with two Families, having four Subfamilies, thirteen genera and about 150 Species. The dentition observed in the Order is both diphydont and heterodont; the members living in the eastern hemisphere possessing thirty-two teeth, those of the western hemisphere having thirty-six, except the members of the Family Calli- TRiCHiDiE which have thirty-two, the excess in the others being accounted for by the presence of an extra pair of premolars in each jaw. In the arrangement adopted the species ascend from the lowest form to the one considered as holding the highest rank, exclusive of Man, but standing nearest to him. The two aberrant forms of the Lemuroidea, Daubentonia and Tarsius head the list, the former remarkable for the peculiar struc¬ ture of the limbs and the specialized second finger, and the rodent teeth ; the latter for its lengthened legs, digits provided with discs, and large eyes. These comprise the F amilies DaubentoniiDjE, and TARSiiDiE. Following these but still of a low order in the Family Nycticibid.e, Subfamily Lorisin^e, come Loris and Nycticebus, the Slender and Slow Lori, with large expressionless eyes, pointed noses xxn INTRODUCTION and tailless bodies. Arctocebus succeeds with its reflexed finger, wide spreading thumb and rudimentary tail, to be followed by Perodicticus whose tail is about one third the length of the body and having long slender processes from the anterior dorsal vertebrae projecting through the skin. The Subfamily Galagin^e follows with its genera Galago with three subgenera and thirty species, having the curious power of folding the ears at will; and Hemigalago. Next comes the Subfamily Lemurin^; containing the true Lemurs and their near allies. It has seven genera, with, altogether, thirty-five species. The members of the seven genera present many characteristic differences from each other, in size, coloration, and peculiarities of crania. The members of one genus, Chirogale, afford a transition between Galago and Lemur. This genus and Microcebus have been considered by some Authors as not divisible, and while their members bear a resemblance to each other, yet they each exhibit sufficient characters to make it advisable to keep them in different genera. They are small animals, some of them the most minute of the Lemuroidea. The last Subfamily of this Suborder is Indrisin^e containing the largest member of the Lemur¬ oidea yet known. The adults have thirty teeth, and the toes, except the hallux, are united to the end of the first phalanx by a fold of skin. The Subfamily has but three genera, Indris with one species, the largest of all the Lemurs, distinguished by absence of tail and excessive variability in the color of pelage; Propithecus with two species and five subspecies. Like Indris the species of this genus are subject to much variation in color, and this has been productive of great con¬ fusion in discriminating between the different forms. They are large animals, with powerful hind limbs enabling them to leap amazing dis¬ tances. When walking on the ground they assume an erect posture and, like the Gibbons, balance themselves by holding the arms over their heads. The last genus is Lichanotus with one species. It is a small animal with a rather long tail, and woolly fur. It is slow in its movements but when on the ground like the other members of Indrisin^e it walks upright. The second Suborder ANTHROPOIDEA contains the remainder of the Primates, including Man. As the consideration of Homo is excluded in this Review, we pass to the Monkeys, Baboons, Apes, etc., which compose the rest of the Suborder. The Monkeys of the ’New World and those of the Old, save in one Family, Callitrichule, are separated by two characters, the number of teeth, and more or less prehensile tails. They are all contained in two Families, the one just mentioned above, and Cebid^e. The first contains the smaller, less INTRODUCTION XXllI intelligent species, delicate of frame and constitution, unable to bear captivity, and soon succumb when taken from their accustomed environ¬ ment. Callitrichhxe contains six genera with about sixty species and subspecies. The members of this Family have only thirty-two teeth and in this respect resemble the species of the Old World, and differ from the rest of the Monkeys indigenous to the western hemisphere. The first genus is Seniocebus with three species, with the head partly bald, and long occipital crest, and without a mane or ruff ; next Cer- copithecus with three species having a mantle ; then Leontocebus having nineteen species, possessing a ruff on neck, and fourth, (Edi- pomidas with three species having the head crested and the hairs on the nape elongate. The fifth genus is Callithrix with thirteen species. These are small creatures, among the most delicate of all the members of the Order, have small canines, tails with long hair, and the angle of the mandible expanded as in Pithecia. Callicebus the sixth genus has twenty-two species, closely allied to the previous genus, and agreeing with it in certain of its characteristics. We now come to Monkeys that are distinctively American with one pair of extra premolars in both jaws, the nostrils directed outward, and the prehensile tail. They are all included in the Family Cebid^e with its four Subfamilies. The first of these is Alouattin^e having but one genus Alouatta with eleven species, and two subspecies, some of them being the largest in size of the New World Monkeys. They are of low intelligence, morose in disposition, heavy in body and with a wonderfully powerful voice. The second Subfamily, Pithecin^e, containing the Sakis, Uakari and Squirrel Monkeys, has three genera the first of which is Pithecia with eight species. These are animals of moderate size, of a more slender figure than the species of Alouatta, with the hair on head, frequently standing upright, long and thick and with a median part. A thick beard hangs from the chin, especially noticeable in the male, and there is also a lengthened bushy tail. In certain species the hair of head is coarse, loosely set, and is directed forward forming a kind of hood around the face. The second genus is Cacajao with only three species characterized by having the face and a large portion of the head naked and brightly colored, becoming more intense and vivid when the animal becomes excited. The tail is very short and the mandible is dilated posteriorly. The *“caecum in C. calvus is upwards of ten inches along the greater curvature ; it is separated from the colon by a very marked constriction , *Beddard, Proc. Zool. Soc. Lond., 1887, p. 119. XXIV INTRODUCTION it is not sacculated, and when fully distended with air is curved on itself into little less than a circle ; it is furnished with a well developed median frenum carrying blood vessels.’ The last genus is Saimiri having eight species. These are small active animals with large eyes, and the occipital region of the skull projected posteriorly. The third Subfamily is Aotin^e with a single genus Aotus con¬ taining fourteen species. These are eminently nocturnal animals, of small size, and with large eyes placed close together. The fourth Sub¬ family is Cebikle with four genera; the first Ateleus, generally known as ‘Spider Monkeys,’ on account of their slender bodies and long limbs, with twelve species. The pollux is usually absent, and the tail prehensile, the animals of this genus being so expert in the use of this organ as to make it perform the service of an extra hand. The next genus is Brachyteleus with only one species; a long limbed, heavy bodied creature, with, like Ateleus, the thumb usually wanting. . It is closely allied to the ‘Spider Monkeys.’ The third genus is Lago- thrix having six species. Unlike the members of the two previous genera, the species of this one have a well developed thumb. The body is heavy, the round head covered thickly with short hairs, and best described as ‘bullet-headed.’ The animals are slow in movement, of a gentle disposition, and a delicate constitution. The fourth genus being the last of the American Monkeys is Cebus with twenty-two species and two subspecies. On account of the great variability in the coloring assumed by individuals, the members of this genus are the most difficult to determine of the Primates. They also, by certain of the species, are most generally known of all Monkeys. The face is flat, the muzzle not protruding. The brain has numerous convolutions, and the animals are intelligent, vivacious and very mischievous. The Apes, Baboons and Monkeys of the Old World comprise the Cratarrhine section of the Primates, or those with, among other characters, the nostrils directed downward. There are only three Families and two Subfamilies possessing, altogether, twenty-two genera. The first Family is Lasiopygide with eleven genera. Papio, the first genus, has nineteen species including the dog-faced baboons, so called on account of their long muzzle. These are large, powerful animals, associating in herds, commanded by one or more patriarchal members, and are formidable antagonists when attacked. Thero- pithecus contains but two species, large in size and heavily maned, in this respect allies of Papio hamadryas. The third genus is Cyno- pithecus the black Apes of Celebes ; peculiar looking animals without INTRODUCTION XXV tails, and very broad rostrum, and the head crested. They are not very closely allied to any of the species of the Primates, but are as well placed here as anywhere, for, although there are many characters to separate them, yet they are probably nearer the species of the genus Magus than any other. One species only is here recognized. Magus with three species serves as a link connecting Cynopithecus and Pithecus. While outwardly resembling the black Ape of Celebes, yet its narrower rostrum, lack of crest on head, which is covered with short hairs, indicate an affinity for the Macaques, and its tailless con¬ dition is similar to that of Simia sylvanus, the only species of that genus. Pithecus is one of the largest genera of the Primates having fifty-three recognized species and subspecies. These vary greatly in appearance, with tails either short and thick, or slender and longer than the head and body. The Macaques are noted for their nude buttocks which are often most highly colored, eyes close together and surmounted by a bony ridge which gives them a scowling expression. The canines are long and make formidable weapons, and the brain is small. The seventh genus is Cercocebus. It has nine species and two subspecies, of a more slender form than the Macaques and with shorter rostrum and longer limbs, but as in Pithecus the last lower molar has five cusps. Much confusion has existed in the synonymy which, it is hoped, has at length been corrected. Rhinostigma is the next genus, with one species, allied to both the members of Cercocebus and Lasiopyga, and forming a link between them. This last named genus is the largest of all and has eighty-five species and subspecies. These monkeys have frequently a pelage of many brilliant colors, have slender bodies and long limbs and tails, and are very active in their movements. The ninth genus is Miopithecus containing only two species of small stature and inconspicuous coloring. Erythrocebus the last genus of the Sub¬ family, had, at one time, its members, like those of the one preceding, included in Lasiopyga ; they, however, differ in many ways from the Langurs, have longer legs, differently shaped skulls, and dwell upon the ground, being frequenters of the plains rather than of the forests, and go in small companies. Twelve species are recognized. The second Subfamily is Colobin^e, frequently named Semno- pithecinc ? with five genera. The first, Pygathrix, has fifty-eight species and subspecies. They are delicate animals, and feed chiefly on leaves and shoots. Their forms are slender and they have no cheek pouches, and their pelage is much less gaily colored than that of the XXVI INTRODUCTION species of Lasiopyga. The Langurs, as they are called, are rarely seen in Zoological Gardens as their delicate constitutions cause them easily to succumb when held in captivity. Rhinopithecus is the second genus with three species, large animals with the nasal portion of the face depressed, the nose very small and the end turned upward giving a very bizarre expression to the countenance. One species has bright colors, roxellan^e, the others are garbed in more sober hues, but their size makes them imposing, and to rank among the finest species of the Primates in the Family to which they belong. The next genus Simias contains but one species, a curious creature apparently, a connecting link between Rhinopithecus and Nasalis as it possesses characters peculiar to each. Thus, it has the upturned nose of the members of the first genus, and also similar teeth, with cranial characters resembling those of the Proboscis monkey. It is altogether, considering the above mentioned peculiarities and its short naked tail with the terminal tuft, not comparable with any species of the Order; a very remarkable animal. Nasalis is the fourth genus with an equally extraordinary species, its greatly lengthened nose turned downward. This organ has a depression in the center and is capable of being dilated. The laryngeal sac is large, and there is a beard on the chin. There is but one species known. The last genus of the Family is Colobus containing the Guerezas of which there are thirty species, composed of the red and black Guerezas, the former constituting about two thirds the entire number. These animals have the thumb absent or rudimentary. They are large in size, and the black Guerezas are ornamented on different parts of the body, with long white hairs falling like a fringe, and the tails are more or less tufted with white. The fourth Family is Hylo- bathle containing the Gibbons, with two genera, Hylobates with twelve species, and Symphalangus with one species and two sub¬ species, one of which, continentis is somewhat doubtful. These flying Apes are, among other characters, remarkable for the length of their arms, which, when the animal is erect, permit the hands to reach the ground. They walk erect, balancing themselves somewhat awkwardly by holding the arms, crooked at the elbow, over the head. The ischial callosities are small and they are the last of the large Ape-like species to possess them. The species and subspecies of Symphalangus are the largest in size, and differ from those of Hylobates in having the second and third toes united by skin up to their last joint, and the skin of the throat is distensible and overlies the laryngeal sac by the thyro-hyoid membrane. IN TROD U CTI ON XXVll The last Family is that of PongiiDvE containing the great Apes, represented by three genera, arranged according as their species are considered nearest to Man. In this Review the Ourang-utan is placed lowest in the scale or farthest from Man; and the genus Pongo is considered to possess but one species certainly, and one very doubtful. The Author is fully aware that this opinion is by no means shared by some of his colleagues, who would recognize a large number of species, but after examining all the material of Ourangs contained in all the large Museums of the world, the writer was able to discover no char¬ acter that would prove the existence of more than one species. The opinions as to the position the Ourang should occupy in reference to Man have varied greatly yet despite the views of so great an authority as that of his friend the late Sir Richard Owen, who would place the Ourang before the Gorilla in its relation to Man, the Author, from the result of his own studies, and the evidence produced by others, con¬ siders that the testimony in its entirety shows that the Gorilla, low as he may be in the scale of intelligence, has more of an affinity for Man than the Ourang, while both are far exceeded in man-like qualities by the Chimpanzee. The second genus then is Gorilla with certainly two species, and seven subspecies of more or less distinctive value. Pseudogorilla has one species, connecting Gorilla and Pan. The last genus is Pan, containing the Chimpanzees, nearest in the scale to Man of all existing earth born creatures. There are at present eleven scheduled species and three not yet named, but how many of these will eventually be able to prove their right to be regarded as distinct species cannot as yet be determined. GENERA. The genera bestowed upon the Primates have been many and of varied importance. Some of course are necessary in order to properly recognize natural divisions of a Family ; a few are useful to segregate, as subgeneric groups, certain portions of a genus which seem to have in common, characters not possessed by other species of the same genus ; but a considerable number of the proposed terms find no legiti¬ mate place, and only help to swell the list of synonyms. In the follow¬ ing arrangement the genera proposed are placed in the various Families to which they belong according to the year in which they were first published, beginning with Linnaeus in 1758, earlier than whom no Author may be recognized.

North of this line in the Nearctic Region no species of the Primates dwells, while in the Eastern Hemisphere only those species belonging to certain islands of the Australian Region are found to the south and east of it. Beginning with the Old World, so called, we find that both Suborders are repre¬ sented, Lemuroidea being entirely absent from the Western Hemi¬ sphere. The species of this Suborder are found in the Malagasy Subregion of the East and West African Subregions, and the Indian and Ceylonese Subregions of the Oriental Region. The Island of Madagascar contains nearly one half of the number of the species comprised in the following genera : Daubentonia, Cheirogale, Micro- cebus, Mixocebus, Altililemur, Lepidolemur, Myoxicebus, Lemur, Lichanotus, Propithecus, and Indris, embracing altogether forty- three species and subspecies out of the one hundred and six belonging to the Suborder. The East African Subregion has one species of Perodicticus, P. ibeanus in the Kakamega forest ; and eighteen species and subspecies of Galago and Hemigalago are found in the East African Subregion, ranging from the vicinity of the White Nile below Khartoum to Mashonaland on the south up to an elevation of 5,000 feet. These are G. dunni; G. sennaariensis ; G. gallarum ; G. HINDSI ; G. KIKUYUENSIS ; G. LASIOTIS J H. THOMASI ; G. BRACCATUS ; G. braccatus albipes; G. panganiensis ; G. badius ; G. zanzibaricus ; G. CRASSICAUDATUS ; G. KIRKI ; G. MOSAMBICUS ; G. NYASS^E ; G. SENE- galensis; and G. montieri. In the West African Subregion are G. senegalensis ; G. pupulus; G. a. cameronensis ; G. elegantulus; G. a. batesi; G. anomurus; G. demidoffi; and G. demidofd poensis, and six others. In the South African Subregion are G. nyass^e and G. granti. The locality of G. e. apicalis is unknown. In the Indian Subregion of the Oriental Region one species of Loris, L. lydekkerianus ; and one of Nycticebus, N. coucang are found, while the Ceylonese subregion has Loris tardigradus. The Indo-Chinese Subregion has four species of Nycticebus : N. pyg- maius; N. tenasserimensis ; N. malaianus; and N. cinereus; and the Indo-Malay Subregion contains seven species of the same genus, viz. : the one last named together with N. hilleri ; N. bancanus ; N. javanicus; N. borneanus; N. natun^e; and N. menagensis. The members of the Suborder ANTHROPOIDEA are widely distributed over the Old World and are found in all its Zoogeographical divisions excepting the Polynesian and New Zealand subregions. The Ethiopian region is the richest in its number of Primates of all the INTRODUCTION lxix divisions into which the Globe has been partitioned. It has already been shown that it contains most of the LEMUROIDEA, and now it will be seen that a large proportion of the ANTHROPOIDEA are also found within its limits, the great continent of Africa being responsible for most of the species. Papio is the first genus of the ANTHRO¬ POIDEA to be considered, and, in the East African Subregion of this Region, it contains twelve species distributed throughout its length from north to south, Nubia, to Lake Nyassa. They are P. CYNOCEPHALUS ; P. HEUGLINI ; P. DOGUERA ; P. NEUMANNI J P. IBEA- NUS; P. TESSELLATUM ; P. FURAX ; P. PRUINOSUS ; P. STREPITUS/ P. hamadryas ; P. h. arabicus from Southern Arabia; and P. brockmani. The West African Subregion has P. Nigeria; P. papio; P. sphinx; P. leucoph^us; P. yokoensis; and P. planirostris ; while the South African Subregion has but one species P. porcarius. Theropithecus has but two species, T. gelada, and T. obscurus ; both natives of Abyssinia in the East African Subregion. Cyno- pithecus and Magus take us into the Austro-Malayan Subregion of the Australian Region, where, in Celebes, and the small islands of Menado-tue, Batchian, Muna and Butan, and doubtfully in the Aru Islands, the few species of these genera are found. The next genus in the order adopted is Simia, with its single species of S. sylvanus found in the southwestern part of the Mediterranean Subregion, in Morocco and Algiers, whence it was introduced on the Rock of Gibraltar. Pithecus, with its many species, is dispersed over all the recognized Zoogeographical Regions of the Old World except the Australian. Beginning with the Palaearctic Region in the Siberian Subregion, Thibet possesses three species, P. vestitus ; P. lasiotis ; and P. thibetanum ; and one from Cashmere, P. villosus ; and P. fuscatus from Japan. The next is the Oriental Region, and in the Indian and Ceylonese Subregions four species are found, P. rhesus ; P. sinicus; P. albibarbatus ; and P. pileatus. In the Indo-Chinese Subregion fifteen species are met with, P. assamensis, and this Macaque goes as far to the west, in the Himalaya range of the Indian Subregion, as Masuri ; P. speciosus; (this species found also in Borneo), P. nemestrinus; P. irus; P. andamanensis ; P. rufescens; P. ADUSTUS; P. INSULANS; P. VITUS ; P. HARMANDi; P. BREVICAUDUS ; P. SANCTI-JOHANNIS ; P. CYCLOPSIS ; P. VALIDUS ; and P. LITTORALIS. The Indo-Malayan Subregion of this region contains twenty-six species dispersed through the lower Malayan Peninsula and the numerous islands of the various Archipelagoes. They are P. capitalis ; P. fas- cicularis; P. nemestrinus; P. umbrosus ; P. fuscus; P. ph^eurus; lxx INTRODUCTION P. AGNATUS ; P. LAPSUS J P. ALACER ; P. MORDAX ; P. RESIMUS ] P.

In East Africa from the Tana River to Uganda and the Upper Congo four species are found : C. galeritus ; C. a. john- stoni; C. chrysogaster ; and C. hagenbecki; and West Africa has the remaining species, six in all, ranging from Sierra Leone to the Lower Congo: C. .ethiops; C. lunulatus; C. torquatus; C. ater- rimus; C. albigena; C. a. zenkeri; and C. agilis. The genus Rhinostigma contains but one species, R. hamlyni, from the Ituri Forest, East Africa, apparently a link between the last genus and the one succeeding, and remarkable for the shape of its face, (which is similar to that of a Barn-Owl), and the mark over the nose from forehead to upper lip, and the small fifth cusp on the last lower molar. The great genus Lasiopyga, containing the largest number of species of all those included in the Order Primates, succeeds Rhino¬ stigma. It is entirely confined to the Ethiopian Region, its mem¬ bers dispersed over the African Continent save along the Mediter¬ ranean littoral. The East African Subregion of the Ethiopian Region contains forty species and subspecies, L. neglecta Schlegel, (nec Auct.) ; L. griseoviridis ; L. boutourlini; L. matschie; L. djam- DJAMENSIS; L.

The South African Subregion has L. albigularis; L. rufoviridis , P. a. beirensis; L. s. mosambicus ; L. pygerythra; and L. lab i at a , six species. Eight remain whose habitat is entirely unknown, L. l hoesti ; L. nigriviridis ; L. inobservata; L. werneri ; L. nigri- GENSIS , L. ERYTHROGASTER ; L. TEMMINCKI and L. ALBITORQUATA. Miopithecus follows Lasiopyga ; indeed up to the present time its species were always included in the last genus. It has only two members, both natives of the East African Subregion of the Ethiopian Region, their range extending from Southern Cameroon to, and including, Angola. They are M. talapoin and M. ansorgei. Erythrocebus contains the long-legged reddish colored Guenons, heretofore included in Lasiopyga. They are inhabitants of the Ethiopian Region, six being dwellers of the East African Subregion, E. pyrrhonotus; E. poliopiueus ; E. albigenis; E. formosus; E. whytei ; and E. baumstarki. Five are inhabitants of the West African Subregion, E. patas ; E. kerstingi ; E. zecki ; E. langeldi ; and E. sannio. The locality of one species, E. circumcinctus, is unknown. We now come to Pygathrix one of the largest genera of the ANTHROPOIDEA. Its members are natives of the Palsearctic and Oriental Regions. Two species only are found in the first of these, P. schistaceus and P. lania. In the Indian Subregion of the Oriental Region is found but one species, P. entellus. In the Ceylonese Sub- region seven species are met with : P. cephaloloptera ; P. c. monti- cola; P. senex ; P. johni ; P. ursina ; P. hypoleuca ; and P. priamus. In the Indo-Chinese Subregion of this Region are found eight species : P. pileata; P. franqoisi ; P. crepuscula; P. c. wroughtoni ; P. Mar¬ garita; P. germaini; P. NEMvEus; and P. nigripes. The Indo- Malayan Subregion contains the remaining species : P. melanolopha ; P. NOBILIS ; P. RUBICUNDA ; P. CARIMATZE ; P. FRONTATA ; P. HOSEI ; P. thomasi ; P. potenziani ; P. aurata ; P. cristata ; P. c. pullata; P. ultima; P. albipes; P. nudifrons; P. cruciger; P. chrysomelas; P. sumatrana; P. batuana; P. percura; P. femoralis; P. mela- mera; P. barbei; P. phayrei; P. flavicauda; P. robinsoni; P. obscura; P. carbo; P. sanctorum; P. nubigena; P. dilecta; P. natun^e; P. rhionis; P. cana; P. siamensis; P. catemana; P. aygula; P. fusco-murina ; P. sabana; and P. everetti. P. holo- tophrea is the only one whose locality is unknown. Rhinopithecus is a small genus with four known species, belong¬ ing to the Siberian and Manchurian Subregions of the Palsearctic lxxii INTRODUCTION Region; and go as far as Tonkin and eastern Thibet. They are R. roxellan^e ; R. bieti ; R. berlichi, and R. avunculus. Simias and Nasalis each with a single species are natives of the islands of South Pagi and Borneo respectively of the Indo-Malayan Subregion of the Oriental Region. Colobus is a genus of the Ethiopian Region its members being entirely restricted to the Continent of Africa, the greatest number of species dwelling in the East African Subregion, and ranging from Abyssinia to Nyassa- land and from Gambia to Angola. In the East African Subregion fifteen species are found, which, beginning with the most northern are as follows : C. abyssinicus ; C. polyurus ; C. gallarum ; C. ELLIOTI ; C. TEPHROSCELES ; C. RUWENZORI ; C. CAUDATUS ; C. RUFOMI- TRATUS ; C. PALLIATUS ; C. KIRKI ; C. GRAUERI ; C. SHARPEI ; C. godonorum ; and C. angolensis. In the West African Subregion are C. BOUVIERI ; C. FULIGINOSUS J C. VELLEROSUS ; C. SATANAS ; C. FERRU- gineus ; C. rufo-niger ; C. verus ; C. a. occidentalis; C. preussi ; C. polycomus; and C. pennanti. Four species are found in Central Africa, and C. temmincki's habitat is unknown. Hylobates or Gibbons are natives of two of the recognized Zoogeographical Regions, the Indian and the Oriental. Of the first of these in the Indo-Chinese Subregion are H. hoolock ; H. lar ; H. LEUCOGENYS; H. GABRIELLI ; H. HENRI Cl J H. PILEATUS; and H. nasutus. In the Indo-Malayan Subregion are H. lar; H. agilis; H. leuciscus ; H. concolor ; H. funereus ; and H. fuscus ; the last two being of doubtful validity. The other genus of Gibbons Sympha- langus has S. syndactylis, with one rather doubtful subspecies, S. s. continentis; and S. klossi ; all in the Indo-Malay Subregion of the Indian Region. We now reach the Pongiidje containing the great Apes, the remaining members of the Primates. Pongo the first genus has one species, P. pygm^us, (a second being doubtfully possible P. abelii,) from the great islands of Borneo and Sumatra in the Indo- Malay Subregion of the Indian Region. The second genus Gorilla has all its members save one in the West African Subregion of the Ethiopian Region. These are G. gorilla; G. g. castaneiceps ; G. g. matschie; G. g. jacobi; and G. g. diehli. In the East African Sub- region G. beringeri is found in the German Protectorate, in all, two species and four subspecies. Of the majority of these it must be said that they are very doubtfully separable from G. gorilla, all the knowledge we have of them having been gathered from very insufficient material. INTRODUCTION lxxiii Pseudogorilla has one species P. mayema? from the Congo forest. The last genus of the Primates of the Old World is Pan em¬ bracing the Chimpanzees. Fifteen species are tentatively acknowledged in this work, but we are without sufficient information regarding them, and their validity is in almost as great uncertainty as is that of some of the species of the genus Gorilla. The ranges of these different species are either not known at all, or very imperfectly, and the greater number of forms are found in the West African Subregion from Sierra Leone to the Gaboon. In this comparatively restricted district of the African Continent all the species of Chimpanzees, save two, so far as is known, are to be met with. They are P. calvus; P. fuligi- NOSUS; P. SATYRUS ; P. KOOLOO-KAMBA ; P. LEUCOPRYMNUS ; P. PYG- mjeus; P. chimpanse; P. aubryi; P. vellerosus; and P. fuscus. All these are found in Gaboon and Cameroon, save two, P. vellerosus absent from Gaboon, and P. satyrus not found in Cameroon. In the East African Subregion two species only are known to dwell, P. schweinfurthi in the Nyam-nyam country, and P. s. marungensis from the vicinity of the Albert Nyanza, and in the Congo forest. In Neogea, embracing the Western Hemisphere, we find the Primates are represented in the Neotropical region only, and Mexico contains the forms that reach the highest northern limit. Here is found a subspecies of Alouatta, A. p. mexiccma in the State of Vera Cruz, and one species of Ateleus, A. pan. Two species are found in Guatemala, Alouatta villosa ; and Ateleus pan. Nicaragua has five species of Primates, one, Aotus rufipes, (but doubtfully a resident of that State) ; Alouatta palliata; Ateleus geoffroyi; A. ater: and Cebus capucinus. Costa Rica is represented by two species of different genera CEdipomidas geoffroyi ; and Saimiri cerstedi ; both also met with in Panama ; and on Coiba Island in the Bay of Panama Alouatta p. coibensis is found. On the Island of Trinidad Alouatta insulanus is met with. On the continent of South America beginning with the Guianas, Brazilian Subregion, five species are found in all: Saimiri sciurus; Aotus trivirgatus; Alouatta macconnelli; Ateleus paniscus; and Cebus apella; some of these having a wide distribution in South America. French Guiana possesses besides the species just named, Cercopithecus rufimanus and Pithecia capil- limentosa; and British Guiana has four additional, Cercopithecus midas; Pithecia satanas; P. chiropotes; and Cebus castaneus. Dutch Guiana has also Cercopithecus midas. Venezuela has eight species of Primates: Cercopithecus ursulus; Callicebus tor- lxxiv INTRODUCTION quatus; Saimiri sciureus; S. cassiquiarensis ; Alouatta ursina; Ateleus variegatus ; A. beelzebuth ; and Cebus apiculatus. Brazil with its immense extent of territory and vast forests contains the greatest proportion of the American Primates. It has two Seniocebus, S. bicolor and S. martinsi ; one Cercopithecus ursulus ; nine Leontocebus ; L. chrysomelas ; L. rosalia ; L. chrysopygus ; L. MYSTAX; L. NIGRICOLLIS; L. IMPERATOR ; L. NIGRIFRONS ; L. LABIATUS ; and L. thomasi. Of Callithrix, it has thirteen species : C. santarem- ENSIS ; C. JACCHUS ? C. ALBICOLLIS ; C. HUMERALIFER ; C. PENICILLATA ; C. p. jordani; C. leucocephala ; C. argentata ; C. aurita ; C. flavi- ceps; C. chrysoleuca; C. pygm^ea; and C. leucopus. Callicebus is represented by three species: C. emille; C. torquatus; and C. amictus. Aotus has five species: A. trivirgatus; A. roberti; A. infulatus; A. miriquouina; and A. vociferans. Alouatta gives three species: A. beelzebul; A. caraya; and A. juara; while Pithecia has six: P. satanas; P. chiropotes; P. albicans; P. chrysocephala ; P. alb i nasa ; and P. monacha. Cacajao is entirely Brazilian and all its three species are found within that territory. Ateleus appears to be represented by only three species: A. mar- ginatus ; A. variegatus; and A. paniscus. The single species of Brachyteleus is a native of Brazil ; and Lagothrix has four species : L. lagotricha ; L. cana ; L. ubericola ; and L. thomasi. Cebus has eight species inhabiting Brazil, C. variegatus ; C. unicolor ; C. macro- CEPHALUS ; C. VERSUTA ; C. LIBrDINOSUS ; C. cirrifer ; C. caliginosus ; C. AZARiE ; and three doubtful, their exact localities being unknown, C. crassiceps; C. vellerosus; and C. frontatus. On the western side of the Continent, Colombia contains sixteen of the species of Primates, one Seniocebus meticulosus ; one CEdipomidas salaquiensis ; one Saimiri sciureus ; three Aotus ; A. vociferans ; A. griseimembra ; and A. lanius ; one Alouatta ; A. seniculus ; four Ateleus ; A. geoffroyi ; A. ater ; A. rufiventer ; and A. hybridus. Lagothrix has but one species lagotricha. Cebus has four and one subspecies : C. flavus ; C. chrysopus ; C. malitiosus ; C. c. nigripectus ; and C. fatuellus. Ecuador, the next State, has twelve species : Saimiri Madeira ; and S. macrodon ; Aotus gularis ; and A. micro- don ; Alouatta .equatorialis ; Pithecia monacha ; Ateleus panis¬ cus; Lagothrix infumata; L. lugens; and Callicebus has C. cupreus; C. PjEnulatus ; and C. leucometopa. Peru has nineteen species: Callicebus torquatus; C. amictus; C personatus; C. cupreus ; and C. subrufus. Saimiri b. nigriceps ; and S. macrodon ; four Aotus : A. trivirgatus ; A. nigriceps ; A. senex ; and A. oseryi: INTRODUCTION lxxv Alouatta has but one species ursina ; Pithecia two, P. satanas ; and P. monacha ; Ateleus one, variegatus. Lagothrix also one, LAGO- tricha ; and Cebus three, C. a. pallidus; C. u. cuscinus; and C. f. peruanus. In Bolivia, the last portion of South America in which Pri¬ mates occur, four species are found : Callicebus donacophilus ; Saimiri ustus; Aotus boliviensis; and Alouatta sara. From the above recapitulation it will be seen that the Brazilian Subregion is the home of the Primates in the New World. Every genus save one, QEdipomidas, is represented within its boundaries, and two, Cacajao and Brachyteleus are not found elsewhere. On the eastern border of the Neotropical region no Primate is found below the southern limit of the Brazilian Subregion, but on the western side the Order has its representatives in Peru and Bolivia of the Chilian Subregion. The geographical distribution of each species, so far as known, is shown in the following list. LEMUROIDEA. DaUBENTONIIDvE. Daubentonia. Range of the Genus. Ethiopian Region. Range of the Species. 1.

From the foregoing it will be observed that the Ethiopian Region contains the largest number of genera of the Primates, viz. : twenty- five, the Neotropical Region next with fourteen, then the Oriental Region with nine, the Palaearctic Region three, and the Australian Region with three. All the species of LEMUROIDEA excepting the species of Daubentonia, Tarsius, Loris and Nycticebus, are natives of the Ethiopian Region. Of the genera of the ANTHROPOIDEA two are common to two of the Zoogeographical Regions, viz. : Pithe- cus and Pygathrix which are represented by species in the eastern portion of the Palaearctic Region and generally, (more particularly as regards the first genus), in the Oriental Region, and one, Tarsius, has species in both the Oriental and Australian Regions. All other genera have their members confined to one Region only. . . , . ‘ . BIBLIOGRAPHY. PRINCIPAL AUTHORS AND WORKS REFERRED TO 1758. Linnaeus (C). Systema Natures. 1762. Brisson (M. J).

The family name of the Anthropoid Apes has been consistently misspelled wherever it appears in this work, and the error was de¬ tected too late to correct it on the earlier pages. It was then decided, as it is found in comparatively few places, to continue it as a uniform error and call attention to it here. The premier genus of the Great Apes is Pongo, and the family name Pongidse, not Pongiidae. This is in accordance with the custom which has caused the acceptance of the subfamily name of the species of the genera Galago and Hemigalo — GalaginvE. On the other hand, if it is deemed desirable to consider this barbarous name as a Latin word with a genitive case, then, of course, the family name would be Pongonidce. There is, however, no rule, known to the author, incorporated in any code, which regulates the formation of native or barbarous words that properly are not declinable, have really no genitive case, or in some cases are not even in Latin form, and have never been adopted in the Latin language. * I A REVIEW OF THE PRIMATES VOLUME I- PLATE I DAUBENTONIA MADAGASCAR1ENSIS.

This extraordinary little animal, possessing characters both of the Rodentia and Quadrumana, and known popularly as the ‘Aye-Aye,’ was first discovered by Sonnerat during his visit to the Island of Madagascar. The name it bears was suggested to Sonnerat by the exclamation “Aye-Aye” of the natives who accompanied him, and I VOLUME I. PLATE 1 Daubentonia MADAGASCARIENSIS. '<#3$ i . ■ DA UBENTONIA 3 who then saw the creature for the first time. Its discoverer had a male and female alive on his ship where they lived for two months, sub¬ sisting on cooked rice. A skin was brought to Paris and presented to Buffon and was deposited in the Museum of the Jardin des Plantes. Buffon considered it allied to the Squirrels, and also that it had some relation to the Tarsier (Tarsius — ?). Gmelin placed it in the genus Sciurus and was followed by Cuvier, who however recognized the fact that while the teeth were those of a rodent, the head was very similar to that of the Quadrumana. Illiger associated it with Tarsius and Galago; and Owen in his masterly treatise on the ‘Aye-Aye’ (1. c.) sums up its position as “related by affinity to the Quadrumana, and by analogy to the Rodentia.” It is now generally conceded to be the sole representative of a distinct family of the Lemuroidea. It is remarkable for various peculiarities such as the nictitating membrane of the eye, the naked ears studded with small protuberances, the attenuated and wirelike middle finger, and the opposable thumb and great toe. The fingers and toes are furnished with compressed pointed claws, excepting the great toe, which has a flat nail and is placed at a right angle to the other toes. The tail is long and bushy and is em¬ ployed as a covering when the animal is sleeping. Teats two, abdomi¬ nal. The os planum of the ethmoid not perceptible. Hon. H. Sandwith, when Colonial Secretary in the Mauritius, obtained an example of the ‘Aye-Aye’ from Madagascar and exhibited it in spirits to Prof. Owen, and this was the first specimen received in England. In a letter to Prof. Owen, Dr. Sandwith says of this animal, which he kept for some time in captivity, “I observe he is sensitive to cold, and likes to cover himself up in a piece of flannel, although the thermometer is now often 90° in the shade. On receiving him from Madagascar, I was told he ate bananas, so of course I fed him on them, but tried him on other fruit. I found he liked dates, which was a grand discovery, supposing he be sent alive to England. Still I thought that those strong rodent teeth, as large as those of a young beaver, must have been intended for some other purpose than that of trying to eat his way out of a cage, the only use he seemed to make of them, beside masticating soft fruits. Moreover he had other peculiarities, e. g., singularly large naked ears, directed forwards, as if for offensive rather than defensive purposes ; then again, the second finger of the hand is unlike anything but a monster supernumerary member, it being slender and long, half the thickness of the other fingers, and resembling a piece of bent wire. Excepting the head and this finger he closely resembled a lemur. Now, as he attacked every night the woodwork of his cage. 4 daubentonia which I was gradually lining with tin I bethought myself of tying some sticks over the woodwork, so that he might gnaw these instead. I had previously put in some large branches for him to climb upon , but the others were straight sticks to cover over the woodwork of his cage, which he alone attacked. It so happened that the thick sticks I now put into his cage were bored in all directions by a large and destructive grub, called here the Montouk. Just at sunset the Aye- Aye crept from under his blanket, yawned, stretched, and betook himself to his tree, where his movements are lively and graceful, though by no means so quick as those of a Squirrel. Presently he came to one of the worm- eaten branches, which he began to examine most attentively ; and bend¬ ing forward his ears, and applying his nose close to the bark, he rapidly tapped the surface with the curious second digit, as a Wood¬ pecker taps a tree, though with much less noise, from time to time inserting the end of the slender finger into the worm-holes as a sur¬ geon would a probe. At length he came to a part of the branch which evidently gave out an interesting sound, for he began to tear it with his strong teeth. He rapidly stripped off the bark, cut into the wood, and exposed the nest of a grub, which he daintily picked out of its bed with the slender tapping finger, and conveyed the luscious morsel to his mouth. I watched these proceedings with much interest, and was much struck with the marvellous adaptation of the creature to its habits, shown by his acute hearing, which enables him aptly to distinguish the different tones emitted from the wood by his gentle tapping; his evidently acute sense of smell, aiding him in his search; his secure footsteps on the slender branches, to which he firmly clung by his quadrumanous members ; his strong rodent teeth enabling him to tear through the wood ; and lastly by the curious slender finger, unlike that of any other animal, and which he used alternately as a pleximeter, a probe, and a scoop. “But I was yet to learn another peculiarity. I gave him water to drink in a saucer, on which he stretched out a hand, dipped a finger into it, and drew it obliquely through his open mouth ; and this he repeated so rapidly, that the water seemed to flow into his mouth. After a while he lapped like a cat, but his first method of drinking appeared to me to be his way of reaching water in the deep clefts of trees. “I am told that the Aye-Aye is an object of veneration in Madagas¬ car, and that if any native touches one, he is sure to die within the year ; hence the difficulty of obtaining a specimen.” The Aye-Aye lives in the trees and is strictly nocturnal, becoming active on the disappearance of the sun. One young is said to be pro- DA UBENTONIA 5 duced at a birth, and the female builds a large nest, two feet in diame¬ ter, of rolled up leaves of the Traveller tree, lining it with twigs and dry leaves and with an entrance on one side. The natives are very superstitious in regard to this animal, and are very unwilling to attempt to capture it. A female Aye-Aye lived for several years in the Garden of the Zoological Society in Regent’s Park, London, and Mr. Bartlett, the late Superintendent, has placed on record (1. c.) some interesting facts regarding its habits. On the voyage it gave birth to one young, which lived only ten days, and the mother was in very poor condition when she arrived, being thin and feeble. It slept during the day, lying on its side with the body curved and the tail spread out and flattened, and used as a covering, almost concealing the animal. At night it was active, moving about its cage in the dark and trying to gnaw its way out. It exhibited no uneasiness when a light was introduced, but tried to touch the lamp with its long fingers. It was in the habit of hang¬ ing by the hind legs, and when so suspended, employed the slender wire-like finger to clean and comb the tail. The same finger was utilized to clean the face, and pick at the corners of the eyes, the nose, mouth, ears, and various parts of the body. While so occupied the other fingers are kept partially closed. Only the left hand was used in feeding and was moved very rapidly. The manner of taking food was peculiar. The fourth finger was thrust into the food, the slender finger being at the same time raised above and behind the others, and the first finger and thumb were lowered. The hand is then drawn rapidly back and forth, the inner side of the fourth finger passing between the lips, the head all the time held sideways, and at each movement the food was deposited in the mouth. Sometimes the animal would lap up the food from the dish, but not often. It never watched for its food or guarded it, for on Mr. Bart¬ lett’s removing the dish while the creature was feeding, it continued to thrust its hand forward, and only discontinued when no more food was procured, and then moved away to search elsewhere. After taking food in a fluid state, it frequently ate portions of wood and bark. It was fed upon a mixture of milk, honey, eggs and any thick, sweet, gelatinous food, but would not touch meal worms, grasshoppers, the larvae of wasps and similar objects. It never uttered any sound or exhibited any anger, neither was it shy. Mr. Bartlett obtained some fresh sugar cane and placed some sticks in the cage, and the Aye-Aye 6 DA U B EN T 0 N I A exhibited much fondness for it, cutting deeply into the cane with its powerful incisor teeth, then the fibre was drawn out and the juice extracted by chewing. Mr. Shaw (1. c.) gives an interesting account of an Aye- Aye he had in captivity, relating its peculiar habits, most of which have already been given in the quoted statements of previous writers, but certain facts are worth recording. He says when his captive in its efforts to escape bit at the wire of its cage he noticed that the incisors of either jaw would separate and admit the wire between them even down to the gum, causing their tips to be a considerable distance apart. It was very savage and struck with its hands, but in the daytime its move¬ ments were slow and uncertain. Regarding the superstitions the natives entertain of the animal, he states that many years ago, the Betsimisaraka, in whose country the Aye- Aye is chiefly found, had occasion to open an old tomb in which an ancestor had been buried. No sooner was an entrance effected than an animal, which was a development of said ancestor, sprang out, and their exclamation of surprise, “Haye-haye,” became the creature’s name. Hence many of these people believe that the Aye-Aye is an embodiment of their forefathers and will not touch it, but when they happen to find a dead one in the forest, they make a tomb for it and bury it with all formality. They imagine that if they try to catch one they will surely die, and this belief extends even to the animal’s nest. If one is given, or picks up accidentally a portion of these structures on which the head of an Aye-Aye has rested, it will bring good for¬ tune; while if it happens to be the part on which the feet had been placed, bad luck or death would surely follow. > .

The little animals which comprise this family are about as large as an ordinary rat, and possess several remarkable characteristics. In their habits they are nocturnal, concealing themselves among the branches of trees or bushes during the day, moving only when dis¬ turbed and becoming very active, and exhibiting often a surprising agility after the setting of the sun. They have small rounded heads with enormous eyes, the pupils of which during the day are contracted to a mere slit, but at night are enlarged to such a degree that they cover nearly the entire iris. The fur is soft and woolly. The legs, which exceed the arms in length, have long slender toes and, like the fingers, are provided with sucker-like discs, which enable them to cling firmly to the branches, or any object upon which the animal may alight during its swift progress, which is performed by powerful leaps that cover at times amazing distances for such small creatures. The tail is long and tufted, and when the animal is in flight, is carried above the line of the body, the end curving upward. The nails on the toes are flat, except those on the second and third digits which are compressed. The lower jaw has two small nearly erect incisors, but those in the upper jaw are four in number and unequal, the anterior ones being the largest, and there is no central gap present. GENUS 1.

In this paper reference is made to Lemur tarsier Erxl., which, it is stated, must be taken instead of Tarsius spectrum Pallas as the name of the species, the Author evidently not being aware of the fact that Erxleben’s species, and also that of Pallas both founded on Buffon’s animal, are quite undetermi¬ nable and therefore both names must be dropped. GEOGRAPHICAL DISTRIBUTION OF THE SPECIES. The members of this genus are found on the islands of the East Indian Archipelago. Seven species have been described, of which two are not yet satisfactorily established. In Borneo we have T. bornea- nus, its range unknown ; in Billiton Island T. saltator is found, and it may probably occur in Banka and Sumatra. In Java T. bancanus was met with; Celebes has T. fuscus, and in the Philippine Archi¬ pelago T. philippinensis occurs on Samar, Leyte, and Mindanao, and T. sanghirensis on Sanghir. It must be considered, however, that the dispersion of the Tarsier is as yet but very imperfectly known, and many other islands probably possess those above named, or contain species not yet discovered.

Ex type Dresden Museum. All specimens are not so red as the type, and some are dark grayish on the back of the head, with the shoulders and upper back washed with reddish ; hands dark brown ; feet pale rufous. An example from Mindanao before me is quite pale, a wood brown with a reddish tinge, the upper back only inclined to rusty. The Philippine Tarsier is more or less a reddish animal, and in the prevalence of this color it differs from the Tarsier of the other island groups in the eastern seas. The following account of the habits of this little animal by Mr. John Whitehead, who obtained specimens in Samar, was published by Mr. O. Thomas in his paper above referred to. Mr. Whitehead states : “This remarkable mammal is found in the islands of Samar and Leyte where it is called by the Biscayas ‘Magou.’ So far as I am aware it has not been obtained in Luzon or Mindoro to northwest of Samar. It probably occurs in the great Island of Min¬ danao, and perhaps in Bohol, to the south of Leyte. “In habits the ‘Magou’ is nocturnal, as the enormous owl-like eyes would lead one to suppose ; it frequents abandoned clearings where the new growth has sprung up to a height of some twenty feet, and in Samar where the ground is also thickly covered with ferns and other TARSIUS 11 plants to a height of some three feet. In such places this little animal easily conceals itself during the day. I had the good fortune to see a ‘Magou’ in such a locality one day in Samar. The Tarsius was clinging to the stem of a small tree just above the fern growth, with its peculiar hands around the tree; it was awake and intently watching my movements, and permitted me to approach as close as I wished; when, doubtless at the least sudden movement of my hands it would have jumped to the ground, and made off in the thick woody growth. During the night the ‘Magou’ is very active, and may often be heard, in localities where they are numerous, uttering a peculiar squeak like a monkey. From its habits of feeding only on insects this animal has a strong Bat-like smell. “In Samar where at different times I kept several ‘Magous’ alive, I found them very docile and easily managed during the day. They fed off grasshoppers sitting on their haunches on my hand. When offered an insect, the ‘Magou’ would stare for a short time with its most won¬ derful eyes, then slowly bend forward, and with a sudden dash would seize the insect with both hands and instantly carry it to its mouth, shutting its eyes and screwing up its tiny face in a most whimsical fashion. The grasshopper was then quietly passed through the sharp little teeth, the kicking legs being held by both hands. When the insect was beyond farther mischief, the large eyes of the ‘Magou’ would open, and the legs and wings were then bitten off, while the rest of the body was thoroughly masticated. My captives would also drink fresh milk from a spoon. After the sun had set this little animal became most difficult to manage, escaping when possible, and making tremen¬ dous jumps from chair to chair. When on the floor it bounded about like a miniature Kangaroo, travelling about the room on its hind legs with the tail stretched out and curved upward, uttering peculiar shrill monkey-like squeaks, and biting quite viciously when the opportunity offered. During the day the pupil of the eye becomes so contracted that it appears only as a fine line, but after dark it is so expanded as to fill up most of the iris. “The popular native idea is that the ‘Magou’ feeds on charcoal, the reason for this being that the animal is generally found after the old plantations have been cut down and burnt, this ‘Magou’ doubtless having returned to its old haunts from which it had been driven by the wood cutters. This delusion is fatal to all captured ‘Magous,’ as they are immediately put on a diet of charcoal, and, therefore, soon starve to death.” 12 TARSI US Tarsius fraterculus Miller.

Very near T. philippinensis, but apparently differs in having the forehead, nose and cheeks buffy white. Color. Like T. philippinensis, but forehead, nose and cheeks buffy white. Dr. Meyer does not describe this species, but has contented himself with comparing it with T. fuscus and showing where it differs from that species. This was easy for it has nothing to do with T. fuscus, but is very doubtfully separable from T. philippinensis. Dr. Meyer does not show where his animal differs from that species, though he says it is allied to it ; in fact, if the figure in the plate is colored cor¬ rectly, it does differ from all known Tarsiers, in its buffy white fore¬ head, nose and cheeks. This, however, is an unsatisfactory conclusion to reach, because it would seem incredible, if the Sanghir examples possessed this remark¬ able peculiarity, that Dr. Meyer did not mention it. I could not find the type of T. sanghirensis in the Dresden Museum and doubt if it is there, and so could not compare it with T. TARSI US 13 philippinensis ; but knowing how rarely a small colored figure gives a correct representation of the original, I should expect to find the present form inseparable from T. philippinensis. Being at present unable to prove it to be the same, I leave T. sanghirensis to occupy a specific rank. Tarsius saetator Elliot. Tarsius saltator Elliot, Bull. Am. Mus. Nat. Hist., N.

The earliest genus proposed for this animal was Tardigradus Boddaert, (1. c.) as shown by Messrs. Stone and Rehn, (1. c.) in their review of the Genus. Unfortunately, however, the name had been previously employed by Brisson in the BRADIPODIDAE, and therefore was not available, and Loris proposed by Geoffroy, (1. c.) the next in succession, became the term to be selected. The members of the family NYCTICIBID2E are small animals, nocturnal in habits, slow in movement and covered with a soft, thick, woolly fur. They are contained in four genera: Loris with two species; Nycticebus with eleven species and subspecies; Arcto- cebus with two and Perodicticus with four species. The eyes are large and the ears erect; the limbs subequal; the tarsi short, and the tail is either short, rudimentary or wanting altogether. The third upper premolar is smaller than the first and possesses one large external cusp, and the last upper molar varies in the number of its cusps in the different genera, being quadricusped in Loris, tricusped in Nycticebus and Arctocebus, and bicusped in Perodicticus.

GEOGRAPHICAL DISTRIBUTION OF THE SPECIES. The two species which represent the genus at the present time have a rather restricted dispersion in the localities they frequent. L. tardigradus is apparently confined to the Island of Ceylon, where it is called according to Tennent, the Ceylon Sloth. The other species L. lydekkerianus is found in the southern part of the Indian Penin¬ sula at a low elevation on the Malabar coast, and in the forests of the eastern Ghats, where according to Jerdon it is common. It is very difficult, however, to determine accurately the dispersion of small mammals such as these, whose habits are strictly nocturnal, for it is 18 LORIS not impossible for them to reside in a locality covered by dense forests and be quite unknown to the people inhabiting the district.

Mr. Lydekker, in the Proc. Zool. Soc. Lond., 1904, p. 346, decided that the animals from India and Ceylon were separable, one being a race of the other, but unfortunately he selected the one from Ceylon as new, and conferred upon it the name of Loris gracilis zey¬ lonicus which was preoccupied by L. ceylonicus given by Fischer, (Anat. Maki, p. 28, t. 7, 8, 9, and 18), also to the Ceylon form. In the next species the tangle caused by Mr. Lydekker conferring a name upon the wrong animal was unravelled by Dr. Cabrera.

This small group of night-loving animals is essentially one of the Oriental Region, ranging in India, Arakan, Assam, Siam, Annam, Tenasserim, Malay Peninsula, Sumatra, Banka, Java and Borneo, the Natuna Group and the Philippines. The N. coucang ranges to the east of the Bay of Bengal, Burma and possibly Assam, but it is practically impossible to define its boundaries as it has been so con¬ fused with N. c. cinereus, and it may eventually be ascertained, that, these species now considered distinct, are not so in reality. The dispersal of N. c. cinereus, which is smaller than N. coucang, is supposed to be in Siam and Cochin China, but it cannot be said that these boundaries are accurately defined, nor can they be, until, through the acquisition of ample material, the exact status of the two forms is determined. In Annam, N. pygm^eus was discovered and in Tenasserim N. tenasserimensis occurs, its range unknown, while N. malaianus is found in the Malay Peninsula and on the west coast of Sumatra. In this Island also N. hilleri has been NYCTICEBUS 23 procured, but its range is unknown ; while in the Island of Banka, to the east of Sumatra, N. bancanus was procured. In Java N. javani- cus is a resident, while N. borneanus represents the genus in Borneo. On Bungaron Island of the Natuna Group, N. natun^e was discovered, and from somewhere in the Philippine Archipelago, locality unknown, N. menagensis was brought. In coloration these animals differ con¬ siderably even among members of the same species, and the hue of the dorsal stripe, usually a very conspicuous marking, varies greatly both in color and extent. Some animals have a conspicuous spot on the crown of the head, others are without this, and the presence or absence of this coloration has been utilized for arranging the different forms into two groups. The manner in which the temporal ridges approxi¬ mate and form a sagittal crest has served also for the arrangements into groups of the known forms, and each method has answered fairly well, although in a non adult animal the skulls fail to indicate whether the temporal ridges will, in the fully mature individual, produce by joining together, a sagittal crest or not. The number of upper incisors varies between two and four, and it is difficult to determine from lack of material, the exact reason for this, whether it is an individual peculiarity, or a character of scientific importance. At the present time this question cannot be satisfactorily answered, but it would seem that, from such evidence as we have, the major portion would indicate individual variation, caused however neither by age nor sex.

Type locality. Tenasserim. Genl. Char. Dorsal stripe bifurcating on the forehead and encir¬ cling the eyes. Color. “Pale rufescent.” Major Tickell appears to be the only one who has seen this animal, and Blanford reproduces Tickell’s drawing in his work on the Fauna of British India. The manner in which the dorsal stripe bifurcates on the forehead, each stripe passing forward and encircling the eyes, is cer¬ tainly peculiar and unlike that of any other member of the genus. Before its distinctness can be established satisfactorily, Tenasserim specimens must be procured and properly compared with examples from other parts of India. Blanford quoting from Tickell’s notes states, that this animal is purely nocturnal and arboreal, and feeds on leaves and shoots of trees, fruits, bird’s eggs, and young birds. It has been observed to raise itself on its hind legs and throw itself upon an insect. As a rule it is silent or only utters a feeble, croaking sound, but when angry and about to bite it emits a tolerably loud grunt or growl. When captured it is at first apt to be savage and prone to bite, but soon becomes very gentle and docile. This animal is tolerably common in the Tenasserim provinces and Arakan, but being strictly nocturnal in its habits, is seldom seen. It inhabits the densest forests and never by choice leaves the trees. Its movements are slow, but it climbs readily, and grasps with great tenacity. When placed on the ground it can pro¬ ceed if frightened, in a wavering kind of trot, the limbs placed at right angles. It sleeps rolled up in a ball, its head and hands buried between its thighs, and wakes up at the dusk of evening tc commence its noc¬ turnal rambles. The female bears but one young at a time. 26 NYCTICEBUS Nycticebus coucang Boddaert. Tardigradus coucang Bodd., Elench. Anim., 1784, p. 67. Nycticebus bengalensis Fisch., Anat. Maki, 1804, p. 30; E.

This is the larger and possibly more common form of Nyctice¬ bus found east of the Bay of Bengal. Its distinctness as a separate species, from N. c. cinereus cannot yet be established with certainty, as the material available is not sufficient for definite decisions to be reached. Blanf ord (1. c.) says that this species is purely nocturnal and arboreal. It feeds on leaves, shoots of trees, insects, bird’s eggs and young birds. It is generally silent or utters a feeble crackling sound. If angry, however, and ready to bite it makes a low growl or grunt. In captivity it soon becomes docile and very gentle, but when first captured is apt to be savage. NYCTICEBUS 27 Nycticebus coucang cinereus (A. Milne-Edwards). Nycticebus cinereus A. Milne-Edw., Ann.

Specimen British Museum. The type in the Paris Museum is greatly faded from exposure to the light, and there is not much more than a trace of the original coloring left on the sides of body and shoulders, but more is to be seen on the dorsal line and rump, although these parts are much paler evidently than during the life of the animal. There are no markings on the face, and only a pale narrow reddish yellow line on center of head from between the ears. The hands and feet were probably silvery gray, but now are a dirty or sooty gray, as the accumulated dust of many years has obscured in a great degree the original coloring. The side of the body turned away from the light in the case is darker than the other, and shows more of the reddish or orange tint, but it is impossible to say what was the original color. The head is paler than the body and is a grayish white, same color as the arms and legs. 28 NYCTICEB US This is the smaller style of Nycticebus, allied to N. coucang, and whether or not they represent two distinct species cannot at the present time be decided. The material available for these, as well as some others of the members of this genus is not yet sufficiently ample, and many additional authenticated specimens are required before the status of these animals can be established. For the present therefore they are permitted to remain as distinct species, although it is most probable, that, in the event of their remaining apart, the N . c. cinereus will only hold a subspecific rank, as a race of N. coucang, as is given to it here.

Flower, writing of the Siamese form under the name of tardigradus, states that in captivity this species will eat bananas, mangoes, and bread and milk. It is also very expert at catching small birds ; and climbs about at night with considerable speed. “At one time,” he writes, “I used to sleep in a hammock swung in a veranda close to a cage of ‘Kongkangs’, and when lying awake on moonlight nights had good opportunities of observing their habits. They could squeeze through the bars of their cage (though I never could make out how they got their bodies through such narrow openings as there were) and roam about ; usually they were back in the cage by daylight ; sometimes they remained absent a day or two, and on one occasion two individuals never returned to me. One kept by itself, made a nice interesting pet, but when there were more than one, I found they would resent being handled and bite ; their bite may be very severe as I know from painful experience, but the stories of its being dangerously poisonous to human beings, are hard to believe. The young are carried under the mother’s belly, holding on tight by all four hands, until they almost equal her in size. Many strange powers are attributed to this animal by the natives of the countries it inhabits ; there is hardly an event in life to man, woman or child, or even domestic animals, that may not be influenced for better or worse by the Slow Loris, alive or dead, or by any separate part of it, and apparently one cannot usually tell at the time, that one is under its supernatural power. Thus a Malay may commit a crime he did not premeditate, and then find that an enemy had buried a particular part of a Loris under his threshold, which had, unknown to him, compelled him to act to his own dis¬ advantage. Its fur is used to cure wounds, and a sailing ship with a a NYCTICEBUS 31 live Loris on board is said never to be becalmed. But its life is not a happy one, for it is continually seeing ghosts ; that is why it hides its face in its hands.” This is a well-defined race of N. coucang, characterized by absence of face markings, and the general gray color distributed generally, but with a slight reddish tinge on the flanks and outer edge of limbs.

Head round ; snout short and flat ; eyes brown, large and round, and slightly prominent; ears about 9/16 in. and hardly projecting beyond hair of head. Neck so short as to give head appear¬ ance of being set squarely on shoulders. Nails of hands flat. Hind legs very crooked, (bowed) with feet turned sharply inwards. General color light rufous, hairs being dark at base, then gray changing to light rufous, with very short gray tips. “White line between eyes extending backward 1 in. from base of nose. Face around eyes dark rufous, the markings extending upwards on forehead. The effect produced is a heart-shaped mark of dark rufous on face, the point of heart being on forehead, the eyes occupying two lobes and separated by the white mark which does not run to tip of heart. Sides of head at back, and of neck, have hairs broadly tipped with gray. Broad stripe of dark brown extends backward for 5 y-2 in. along spine tapering to a point. Hairs of arms lighter rufous than that of back. Back of head gray, nearly white. Back of feet grayish. Hair on back of body, arms and legs thick and soft, making a fine fur like that of Galeopithecus. On under surface of body hair is thinner and somewhat lighter in color than on back. About the genitals is buffy white. Measurements. “Total length, 11 in. Tail, in.” “This curious little animal is known to the natives of the region it inhabits as cocane. An adult specimen from which the description was taken, was kept alive by us for seven days. Its movements were sluggish except in biting when its sudden and unexpected activity proved a painful surprise. It moved with equal ease along the upper and lower sides of a small branch or rope, and progressed quite as rapidly backward as forward. On the floor it was not at home and presented a most ludicrous appearance, tumbling along on all fours with feet nearly as far apart as those of a turtle, and its body barely NYCTICEBUS 33 raised from the boards. It spent most of the day asleep, rolled up into a furry ball with its head buried between its thighs. If disturbed when actively climbing about, it had a curious way of folding its hands over its eyes and from hence earned the name of ‘shame face’ which it shares with the Tarsius spectrum, (T. philippinensis) . It had two notes, a low complaining grunt, and a sharp squeal. During its con¬ finement it took little food, turning up its nose at lemons, but occasion¬ ally eating a little banana or egg. We had no insects or small mammals to offer it. In drinking, it lapped up the water like a dog. After five days of semi-starvation its strength seemed almost unimpaired, and it showed remarkable tenacity of life.” The above was taken from the Zoologischer Anzeiger, ostensibly by Dr. Nachtrieb, but he in a letter to Dr. Lyon disclaimed the authorship and stated that the article was probably by Mr. Dean Worcester. Having no genus the name could not stand, but the specific name, menagensis, was afterwards coupled with Nycticebus by *Troues- sart, f Stone and Rehn, and JLydekker (1. c.) and so it came properly into the species of that genus.

Body rather slender; head oval; muzzle blunt, dog like; eyes large; lower phalanges of hands and feet, except of thumb, united in the skin; two upper joints free; index finger reduced to a tubercle, without a nail. Limbs subequal, the hind ones being slightly longer than the fore limbs. The feet are larger than the hands ; the great toe has a rather large fleshy tubercle at its base on the inner side, and is opposable to the other toes ; the nails are thin and flat except that of the second toe which is like a claw, being thin, convex and acute. Ears erect; two transverse ridges lie above the auditory meatus, with fine hairs on the inner margins standing upright. Unlike the species of the genus Perodicticus, the processes of the cervical vertebrae do not project through the skin. Tail rudimentary. Anterior upper molars with four cusps, and oblique ridges ; last upper molar with three cusps ; last lower molar has five cusps. The species of this genus are nocturnal in their habits and move about but seldom during the day, and it is on this account, probably, that hardly anything has been recorded of their mode of life.

This species described by de Winton from an unique example collected by Mr. Bates, is quite unlike in general appearance the only ARCTOCEBUS 37 other known form of the genus. Unfortunately the skull could not be found in the British Museum Collection. Mr. Bates says (1. c.) “The single specimen I sent to the Museum is the only one of this animal I have ever seen. I found it in a village on the Benito River where it had just been killed by a native, who did not know what to call it. However I have sometimes heard from natives of a rare beast like the Potto, which must be the same.” 38 PERODI CTICUS GENUS 4. PERODICTICUS. POTTOS. 2— 3—3 c. 1—1 1— 1> 3—3 2— 2 > M. 3—3 3—3 = 36.

Bosman, who first made known the existence of this animal, gives a quaint description of it and its habits, with a rude drawing. He states, “Draught of a creature, by the Negroes called Potto, but known to us by the name of Sluggard, doubtless from its lazy, sluggish nature, a whole day being enough for it to advance ten steps forward. “Some writers affirm, that when this creature has climbed upon a Tree, he doth not leave it until he hath eaten up not only the Fruit, but the leaves entirely ; and then descends fat and in very good case in order to get up into another Tree; but before his slow pace can com¬ pass this he becomes as poor and lean as ’tis possible to imagine ; and if the tree be high, or the way anything distant, and he meets nothing on his journey, he invariably dies of Hunger betwixt one tree and the other. Thus ’tis represented by others, but I will not undertake for the truth of it, though the Negroes are apt to believe something like it. “This is such a horrible ugly Creature that I don’t believe any¬ thing besides so very disagreeable is to be found on the whole Earth ; the Print is a very lively description of it. Its fore feet are very like Hands, the Head, strangely disproportionately large; that from which this Print was taken was of a pale Mouse color, but it was then very young, and his skin yet smooth, but when old, as I saw one at Elmina in the year 1699, ’tis red and covered with a sort of Hair as thick set as Flocks of Wool. I know nothing more of this animal than that ’tis impossible to look on him without Horrour, and that he hath nothing very particular but his odious Ugliness.” PERODICTICUS 41 Poor Potto ! not a very flattering portrait indeed, but the earliest authors not infrequently indulged in similar descriptions of strange and little known animals. The Potto is strictly nocturnal in its habits and would not be likely to go “anything distant” during the daytime, and although its movements are slow and performed with deliberation, it would survive a sufficient length of time to reach a new food supply, and as it is a dweller of trees it is not likely to attempt any considerable journey on terra firma.

Measurements. Total length, 380; tail, 40; hind foot, 75 ; ear, 23. Skull: occipito-nasal length, 63; Hensel, 54; zygomatic breadth, 21; palatal length, 20; breadth of braincase, 30; median length of nasals, 15 ; length of upper molar series, 18; length of mandible, 29; length of lower molar series, 16. Ex type P. batesi in British Museum. In color this is a very variable species, examples from the same locality differing in this respect from each other. There are six speci¬ mens of this Potto in the British Museum from the Benito and Ja rivers in the French Congo, West Africa, differing very considerably from each other in the hue and marking of their coats. The prevailing color aboA^e is black and chestnut red, but the underparts vary from dark gray mixed with red to ashy gray, and one mounted example from the Benito River, which however may have faded somewhat, has no black at all on the upper parts which are yellowish gray about the shoulders, becoming red on lower back and thighs. The ends of the tails in some specimens are black as described by Bouvier. It would seem to be quite evident from an examination of the examples in the Paris and British Museums that P. edwardsi and P. batesi represent the same species of which Bouvier’s animal is one of the dark style, and the type of P. batesi one of the pale hue. Mr. Bates, who learned about this animal in Southern Cameroon, although on account of the density of the forests, he was unable to meet with one himself, states that “the two or three species of Perodic- ticus of which the names have been sent to me I have not learned to distinguish with certainty ; in the little I have to say I must mention 44 PERODICTICU S them together. They are found in the daytime curled up asleep in the trees, tightly clinging to a branch. So tight is their grip of the branch that specimens have sometimes come to me mutilated in the hands, the natives who captured them declaring that it was only by cutting the fingers that they could loosen the animal’s hold. “Pottos are sometimes caught in traps placed on a horizontal pole or bridge crossing on an open place between two pieces of forest, such as a narrow place in a garden clearing or a stream. The animal crosses on a pole in preference to descending to the ground. One specimen was killed at night on the roof of a house to which it seemed to have wandered from the overhanging plantain tops.” VOLUME I. PLATE VIII. Galago crassicaudatus. No. 8.1.1.25. Brit. Mus.

Fur thick, woolly; eyes large, approximate; ears large, hinder edge contractile at will of the animal ; fingers and toes long and slender, with terminal discs ; tail long, thick, bushy. Skull : braincase round, high, broad ; muzzle short ; squamosal region inflated ; upper incisors small subequal, with posterior cusp on cingulum ; diastema posterior to canine; first upper premolar with one main cusp and two supple¬ mentary ones on each side ; middle premolar with three cusps ; last molar, in some forms, is tricuspidate, in others quadricuspidate ; the last internal cusp wanting. Tarsus long, calcaneum over one third the length of tibia ; tail longer than the body. The species of this genus are all African, and are remarkable for their large ears, and elongated tarsi, the latter much exceeding in length the arms. They have four incisors in both the upper and lower 46 GALAGO jaws, and in size are about equal to a small rat. Various genera have been proposed for these animals, some of which may be advantageously used as subgenera to include certain species with special affinities for one another, but the groups can only be properly separated into two, Galago and Hemigalago, distinguished by the presence or absence of a cusp on the heel of the second upper premolar. LITERATURE OF THE SPECIES AND SUBSPECIES. 1796. E. Geoffroy St. Hilaire, in Magasin Encyclopedique. In this publication Galago senegalensis is first described from Senegal, West Africa. 1806. Fischer, in Memoir es de la Societe Imperiale des Naturalist es de Moscou. Hemigalago demidoffi first described from Senegal, West Africa, and G. senegalensis redescribed as G. geoffroyi. 1812. E. Geoffroy, in Annales du Museum d’Histoire Naturelle, Paris. In a paper entitled “Suite au Tableau des Quadrumanes,” this author mentions four species under the genus Galago, viz., G. madagascariensis which is a Microcebus, probably M. murinus; G. senegalensis; G. crassicaudatus described for the first time, and H. demidoffi, which belongs to a different genus Hemigalago. 1820. Desmarest, Mammalogie. In this work under the genus Galago, five species are recorded, only three of which can be retained, viz., G. crassicaudatus ; G. senegalensis; and H. demidoffi. The other two are G. potto = Perodicticus potto E. Geoff., and G. madagascariensis — Microcebus murinus (Miller). 1837. Waterhouse, in Proceedings of the Zoological Society of London.

In this volume under the term Otolicnus Wagner gives O. galago Schreb., citing only Plate XXXVIII B, but no page. This plate is lettered G. senegalensis, and he makes Geoffroy’s GALAGO 47 G. senegalensis a synonym. The fact is Schreber never de¬ scribed a species by the name galago, and therefore the position is exactly reversed, galago Schreber being non-existent, senegal¬ ensis Wagner becomes a synonym of Geoff roy’s species. Two other species are given for the genus, O. crassicaudatus and O. ALLENI. 1840. Lesson, Species des Mammiferes Bimanes et Quadrumanes. Two species and three varieties are given in this List.

Under Otolicnus, here employed as a genus, five species are given : O. galago = G. senegalensis ; O. alleni — G. alleni ; O. crassicaudatus = G. crassicaudatus; O. garnetti — G. gar- netti ; and O. madagascariensis — Daubentonia madagas- CARIENSIS. 1855. Wagner, Schreber, Sdugthiere, Supplement. Under Otolicnus six species are here given, viz. : 0. crassicau¬ datus ( Geoff roy) ; 0. garnetti (Ogilby) ; O. galago Schreber, non-existent; 0. alleni (Waterhouse); 0. minor Gray, (a Microcebus) ; and O. demidoffi (Fischer). O. galago Schreb., non-existent, is divided into three sections, but the sections are treated as synonyms. These are 0. teng (Sundevall), with sennaariensis as its synonym; O. sene¬ galensis (Geoff roy) ; and O. moholi (Smith), with a new name australis, as its synonym, which is synonymous with G. senegalensis Geoff roy ; O. minor (Gray), is a Microcebus and synonymous with M. murinus (Miller). 1856. R. G. Dahlbom, Zoologiska Studier afhandlande Djurrikets Naturliga Familijer. Four species are here recognized in the genus Galago: G. CRASSICAUDATUS ; G. ALLENI ; G. SENEGALENSIS , and G.

Four forms were here first described ; Galago monteiri as Callotus monteiri from Cuio Bay, West Africa; Galago alleni gabonensis as Galago alleni var. gabonensis from the Gaboon. Galago elegantulus pallidus as Galago pallidus from Fernando Po, and Galago sennaariensis from Sennaar, Eastern Africa. 1864. J. E. Gray, in Proceedings of the Zoological Society of London. Galago monteiri kirki first described as Otogale crassicaudata var. kirki, from Quillimane, East Africa. 1870. J. E. Gray, Catalogue of Monkeys, Lemurs and Fruit-eating Bats, in the British Museum. In his tribe Galagonina the Author arranges the species of Galago in two genera, Otogale, and Galago. In the first are placed garnetti ; crassicaudata ; monteiri and pallida ; and in the second are included alleni ; moholi = senegalensis ; senegalensis ; sennaariensis and demidoffi. The four species of the Otogale group are recognized as valid at the present time, but of those given under Galago, moholi is a synonym of senegalensis Geoff., the name sennaariensis is antedated by Lesson in 1840. Three species are mentioned as not seen by the Author, G. conspicillatus = senegalensis Geoff., 0. peli Temm., = Hemigalago demidoffi Fischer, juv. and O. senegalensis Peters, = G. s. mossambicus Peters. 1876. Schlegel, Museum d’Histoire Naturelle des Pays-Bas, Simice. Five species are included in the genus Galago, viz. : G. cras¬ sicaudatus; G. garnetti; G. alleni; G. senegalensis; and H. demidoffi. G. monteiri is considered to be merely a pale variety of G. crassicaudatus ; the range of G. senegalensis is given from Senegambia and Sennaar to Cafraria, the form from Sennaar not being recognized as distinct. GALAGO 49 1876. Peteis, in Monatsberichte Konigliche Preussen Akademie der Wissenschaften, Berlin. Three forms described for the first time Galago lasiotis from Mombassa, East Africa.

M. E. de Pousargues, in Nouvelles Archives du Museum d’His- toire Naturelle de Paris. A review of the genus Galago is here given, with a full description of H. anomurus for the first time. The Author accepts three sub-genera, Otolemur, Otolicnus and Hemigalago, and reviews the different forms belonging to each and dis¬ cusses their various claims for distinct rank. He recognizes the following as species. Under Otolemur he accepts G. crassi- caudatus ; G. monteiri ; G. garnetti ; and G. agisymbanus = G. crassicaudatus. In Otolicnus he gives G. elegantulus ; G. senegalensis and G. alleni ; and in Hemigalago he places G. anomurus and G. demidoffi. The Author labored under the disadvantage of not having a personal knowledge of many of the forms he rejected, which, if he had had the opportunity of examining might have caused him to reach different conclusions in some cases. 1901.

The Bush Babys, by which name the members of the genera Gala- go and Hemigalago are known, are found upon the African Con¬ tinent, between Sennaar and Natal on the east, and Senegal and Por¬ tuguese West Africa on the west. They are also natives of the islands of Zanzibar on the east coast, and Fernando Po in the Gulf of Guinea on the west. As is the case with most of the groups among the Pri¬ mates, it cannot be said that the distribution of the members of these genera are satisfactorily known, and some may have a much greater dispersion than is here recorded. It is quite evident that distinct forms are fairly numerous, but the material at present available is not sufficient, (a number of species or races being represented by only a few examples, and from either a single, or a very limited number of localities), for a definite geographical distribution to be given. There¬ fore the following ranges assigned to the various members of the genus can only be regarded as approximate, based upon our present rather imperfect knowledge of their habitats, and subject to future rearrange¬ ment as the acquisition of more material shall serve to increase our knowledge. GALAGO 51 A majority of the various species and races is found on the eastern portion of the Continent, extending from Somaliland, Sennaar and the vicinity of the White Nile below Khartoum on the north, to Mashona- land on the south, including the Island of Zanzibar. In the most northerly part of this eastern section at Faffan, near Harrar in Somali¬ land G. dunni was discovered; G. sennaariensis is found ranging southward to Ankole west of Victoria Nyanza, and Nyassaland, and then as far as Mashonaland up to an elevation of 5,000 feet. Next, in the Boran Galla country northeast of Lake Rudolph in Abyssinia, G. gallarum has been obtained, its range however not having been yet ascertained. At Ivatwi on the Athi River in British East Africa, G. hindsi, and at Escarpment Station, G. kikuyuensis have been obtained. From Mombassa on the coast comes G. lasiotis, recogniz¬ able by the white tip to the tail, but how far it may extend into the interior, or whether it is confined to the forest along the coast has not been determined. In Uganda to the north and west of Victoria Nyanza, H. thomasi belonging to the genus Hemigalago is found, the species having been taken at Dumo and Fort Beni on the Semliki River. Whether it is confined to Uganda, or extends its range beyond the river into the forests of the Congo Free State is not known. At Kirui, Elgon, 6,000 feet altitude, G. braccatus albipes was discovered. German East Africa contains several species of Galago, and in the northern part on the heights of Mt. Kilimanjaro, G. braccatus is found. On the banks of the Pangani River not far from the coast G. panganiensis has been procured, while in the interior on the Ugalla River east of Lake Tanganyika, the rather remarkable species G. badiuS was discovered. The island of Zanzibar has apparently two species, G. zanzibaricus, and G. crassicaudatus, the latter under the name of G. agisymbanus, but there seem to be no adequate reasons for separating the island form specifically from the animal dwelling on the coast opposite and ranging through the forests as far south as Quili- mane, Mozambique, where also G. kirki is found. Coming from Nyassaland and extending its range into the interior to Tete on the Zambesi in British Central Africa, G. mossambicus occurs. In this district in Nyassaland south of the Lake in the mountains, and also from Zomba to the southeast of Lake Nyassa we have G. nyass^:, which ranges southward in Portuguese Southeast Africa to Inhambane. South of this, in the vicinity of Delagoa Bay, G granti is met with. From Zululand comes G. zuluensis, and finally completing the list 52 GALAGO of eastern and central African species, in Natal we have G. garnetti, the most southern member of the genus. On the western side of the continent, the most northern species is G. senegalensis from Senegal south to Angola; at Yola, Nigeria, G. fupulus has been obtained, and from Cameroon, we have G. cameronensis, G. elegantulus, G. e. pallidus, and G. alleni ; G. elegantulus tonsor was procured on the Benito River, Guinea. In Equatorial Africa from the mountains, near the Equator, exact lo¬ cality unknown, G. e. apicalis was procured by Du Chaillu ; and at Mombuttu, H. demidoffi was obtained by Emin Pasha. On the Gold Coast H. demidoffi is found ranging south to Gaboon in French Congo, where also G. alleni and G. a. gabonensis are met with, and on the banks of the Kemo River in the same Province, G. a. batesi and H. anomurus were procured. From Cuio Bay south of Loando, Angola, Portuguese West Africa, G. monteiri, one of the larger mem¬ bers of the genus, was obtained. On Fernando Po, an island in the Bight of Biaffra, Gulf of Guinea, three species dwell, G. alleni, G. elegantulus pallidus, and H. demidoffi poensis. KEY TO THE SPECIES AND SUBSPECIES. A.

G. agisymbanus appears to be the same as. the present species, for I can find no characters upon which they can be separated. Coquerel’s type, which is in the Paris Museum, is a young animal. The following is a description taken from it. Head and entire upper parts, and outer side of limbs dull russet, inclining to rusty on top of head and fore¬ arms ; under parts pale greenish yellow ; hands and feet blackish brown ; tail reddish, inclining to blackish brown on apical portion. The adult is dull brown on the upper parts. 56 GALAGO Geoffroy’s type is in the Paris Museum, but is so faded that but little of the original color remains. The tail has lost most of the hair on the apical half, and the example is in such a condition that a descrip¬ tion of it would only serve to mislead. Kirk states (1. c.) that at Luabo and Quilimane, this species frequents the Mangrove forests and wooded country outside. In captivity it eats flesh, vegetables, fruits and insects; in its native state it is fond of palm wine, robbing the pots used by the natives to collect it. This often leads to its capture when it drinks to excess. During the day it remains quiet in some shaded tree top. At night it is very active, leaping from frond to frond, or crossing from one cocoanut palm to another. Coquerel (1. c.) says that this species, (under the name of Otolemur agisym- banus), was brought to him from the interior of the island, while he was staying in Zanzibar, and is common in the forests which cover the northern part. He kept one alive for fifteen days, and it was very gentle. It slept during the day covered by its long tail, but at night it was active and exhibited an extreme petulence. It was fed on fruit but would eat anything, and devoured eagerly meat both raw and cooked. Galago zuluensis Elliot. Galago zuluensis Elliot, Ann. Mag. Nat. Hist., XX, Ser. 7, 1907, p. 186.

GALAGO 57 This species is about the same size in body as G. hindsi, but has a considerably shorter and much darker tail ; it is much darker brown color throughout. When lying side by side, G. hindsi appears like a gray animal in comparison. The ears of the present species are about a third larger than those of G. hindsi both in length and width. In their dried and shrunken state they measure 31 mm. in length and 27 mm. in width, while those of G. hindsi are 24 mm. long by 22 mm. wide, and as the collector’s measurement of the ears of the latter species was 39 mm. in length, allowing for the same shrinkage those of G. zuluensis would be 8 or 10 mm. longer. There is such a vast difference in the size of the skull and teeth that they admit of no comparison. In color G. zuluensis is like G. grassicaudatus, but has a much smaller skull it being midway between G. crassicaudatus and G. hindsi with all the differences such a disparity of size would create. G. garnetti is of an entirely different color, but about the same size. Galago panganiensis (Matschie). Otolemur panganiensis Matschie, Sitzungsb. Ges. Naturf. Freunde, 1906, p. 278. Type locality.

Size large ; ears very large, naked on outer apical edges ; hairs on face short ; feet and toes broad, discs rounded ; tail very long. Color. General hue uniform pale gray over upper part of body, outer side of limbs, and entire tail ; orbital ring black ; hands and feet dark brownish gray; ears black; middle of breast and abdomen white; flanks grayish white. Some specimens are mouse gray on body and tail. Measurements. Total length, 1118; tail, 408. Skull : occipito-nasal length, 70; Plensel, 57; zygomatic width, about 40, (broken); inter¬ temporal width, 19; palatal length, 28; breadth of braincase, 31; median length of nasals, 20 ; length of upper molar series, 23 ; length of mandible, 47 ; length of lower molar series, 20. This is one of the largest species of the genus, with a very long bushy tail. While the color among individuals varies somewhat, the dominant hue is always gray, ranging from a whitish to a mouse gray, with occasionally reddish tints appearing on head and back. The type 60 GALAGO could not be found in the British Museum. It probably never was in the collection. The identification of this animal as a new species should undoubtedly be placed to the credit of the late Mr. A. D. Bart¬ lett, Superintendent of the London Zoological Society’s Gardens, but his MS. having been shown to Dr. Gray, it was included by him in his paper on the species of Lemuroids under Mr. Bartlett’s MS. name in an earlier part of the Society’s proceedings, and thus became G. mon- teiri Gray, manuscript names having no standing. Mr. Bartlett had the type alive, and states it was “very gentle and slept much during the day, and fed on fruit, bread, milk and other sweet things, par¬ ticularly bananas. It had the power of turning its ears back and folding them up when at rest. When moving about or in search of food they, (the ears) spread out and stand upward and forward, reminding one of the Aye- Aye ; but when folded back and down, the animal’s face bears a strong resemblance to the Douroucouli. The pupils of the eyes are oval and vertical.” Galago kirki (Gray). Otogale crassicaudata var. kirki Gray, Proc. Zool. Soc. Lond., 1864, p. 456. Galago crassicaudatus Sclat., Proc. Zool. Soc.

GALAGO 61 This animal has the same gray color as G. monteiri and would seem to be more a representative of that species on the eastern coast of Africa, than a near relative of G. crassicaudatus, which is quite differently colored. It is easily recognized from G. monteiri by the russet coloring on the head and middle of back, and the darker tail. It would seem advisable to recognize it as a distinct species, and not as a race of G. crassicaudatus as Gray made it. This is one of the largest species of Galago, and has a very long and bushy tail. Like other species of the genus it is arboreal and nocturnal in its habits, and is rarely seen during the day, “sleeping in some hollow tree, waking up at sundown, at which time and throughout the whole night its peculiar cry can be heard. At Eshowe it frequents the trees close to the houses, and is said to be extremely fond of fowl’s eggs. The specimens secured were shot at night with the aid of a dark lantern, flashing it suddenly into a tree where one was heard calling. This is a favorite method with the natives for obtaining them, by whom the skin is highly valued. Specimens from Natal seem much browner than those from Zululand.” (Grant’s notes on Zululand Mammals; Thos. and Schwann, 1. c.). In another paper on Mammals from Portuguese South Africa, Thos. and Wrought. (1. c.) quote from Mr. Grant’s notes as follows on this species. “Very common in the forests, where they appear to consort together in small parties. The species has a variety of calls, none of which however are similar to that of Galago garnetti. Apparently principally vegetarian, and feeding largely on the exudation from the bark of certain trees. Strictly nocturnal, passing the day in hollow trees.” Gajlago lasiotis Peters.

Ex type British Museum. This animal is somewhat smaller than its relatives, G. crassi¬ caudatus and G. garnetti, the skull being very considerably smaller. It also differs in its pale color, and the very long pale almost white tail. It belongs to the group of which G. crassicaudatus is the represen¬ tative member. Two specimens are in the British Museum Collection slightly varying in color, the paratype having a darker tail which unfortunately has lost half of its length.

Galago ( Otolemur ) kikyuensis Lonnb., Ann. Mag. Nat. Hist., IX, 8th Ser., 1912, p. 64. Type locality. Escarpment Station, British East Africa. Color. “General colour pale greyish brown, somewhat darker on head and upper neck, outside of limbs more chamois ; throat and lower side of neck with an ochre-yellow tinge ; under side of body dirty white ; hands and feet dark brown, inclining to blackish; tail dark brown, gradually darkening to blackish towards the distal third, paler below. Ears naked.” Measurements. “Total length about 62 cm. ; tail about equal to head and body. Skull : greatest length, 61 ; basicranial length, 49 ; zygomatic breadth, 41 ; palatal length, 23 ; length of upper molar series, 19.5.” I have not seen a specimen of this animal, and as Herr Lonnberg makes no reference to any species with which it may be compared, it is difficult to assign it to its proper place in the genus. In size it seems to be nearest to G. hindsi Elliot, from Katwi, Athi River, British East Africa, and in color appears to differ mainly in the underparts being “dirty white” instead of white, “tail dark brown, gradually darkening to blackish towards the distal third, paler below,” instead of tail above pale wood brown, beneath whitish. It may be remarked that the type localities of these two Bush-Babys are not far apart. Without a careful comparison, it is impossible to state what claims this animal has to a distinct specific rank. As it is impossible to de¬ termine this at preseijt, it is here given the benefit of any doubt that may arise. Subgenus 2. Otolicnus. Size small ; muzzle short ; last upper molar may be tricuspidate or quadricuspidate, but the last lower molar is always quinquicuspidate. Angle of mandible produced backwards and slightly downward.

Bates states that the emam is “found in the daylight in hollow trees, three or four huddled together asleep. An emam that was GALAGO 65 brought to me alive showed great powers of jumping. A monkey can jump outwards and downwards and catch a branch, but this Galago could jump out and up and catch hold of a branch. It died in the hot sunshine when I was away from camp ; it had probably never felt sunshine before.” Galago alleni cameronensis (Peters). Otolicnus alleni var. cameronensis Peters, Monatsb. K.

While allied to G. gallarum Thomas, it is easily distinguished from the type of that species by its dark gray color, and the abruptness with which the buff and gray of the legs come together. As is to be expected of an animal living upon a high mountain the fur is thick and long. There are no appreciable differences in the skulls of the two species. Galago braccatus albipes Dollman.

Type locality. Mountains south of Lake Nyassa, Portuguese East Africa. Type in British Museum. Genl. Char. Fur woolly; tail bushy; skull, much broken, exhibits great differences from that of the species I call G. sennaariensis from the White Nile southward to Ankole, west of the Victoria Nyanza. The rostrum is long and more slender, and the nasals are long and narrow; the palate is long and narrow and does not widen out posteriorly to anything like the extent as seen in skulls of G. sen¬ naariensis ; the anterior line of the orbit is in front of the first molar, instead of in front of the third premolar as in the other species ; there is only a slight rise of the frontal above the rostrum, thus making GALAGO 71 the superior outline of the skull very much less rounded, indeed quite flat as compared with that of G. sennaariensis. Of the braincase only the frontals and parietals remain, the occipital region and bullae, and lower portion of skull on one side even to the palate, having disap¬ peared, so no comparison can be made beyond those already given. Color. General hue above broccoli brown; outer side of arms broccoli brown ; legs cream buff ; under parts and inner side of limbs yellowish white ; cream buff on chest. Ex type in British Museum.

Ex type in British Museum. The type in the British Museum Collection of skins and an ex¬ ample in alcohol from Zomba, Nyassa, are all that are known of this species. While the skin resembles in color G. gallarum more perhaps than any other, the skull in its long and narrow rostral region, and low crown is very different. The type was procured by Dr. Kirk when he was accompanying Dr. Livingstone, the famous Explorer. Galago granti Thomas and Wroughton. Galago granti Thos. and Wrought., Proc. Zool. Soc.

This is a pale species with a long bushy tail, and belongs to the small forms of the Galago senegalensis group, and does not approach very nearly in color to any of the other species. Mr. Grant, as quoted by Messrs. Thomas and Wroughton, states that at Cogungo, Inham- bane, it was “common and inhabited the forests. It is strictly noc¬ turnal, sleeping during the day in hollow trees, where it may generally be taken in small family parties. This species like many others is eaten by the natives.” Galago senegalensis E. Geoff roy. Galago senegalensis E. Geoff., Mag. Encyclop., 1796, p. 41, pi. I; Fisch., Anat. Maki, 1804, p. 42; Id. Syn.

Distr. Senegal, Angola, (Cameron). Genl. Char. Ears large, bare ; legs longer than arms ; posterior upper premolar smaller than the middle and posterior molars ; pos¬ terior premolar and first and second molars have a small cusp between the two front cusps ; upper incisors four. Color. Head, Prout’s brown, the hairs tipped with gray; upper parts dark gray washed with russet ; outer side of legs cream buff ; under parts yellowish white; hands brown, feet blackish; tail, basal portion similar to back, remainder burnt umber ; a white streak between eyes and nose ; ears pale brown. The type in the Paris Museum has top of head Prout’s brown, shading into yellowish gray on the back of neck ; rest of upper parts pinkish buff, becoming more cream buff on outer side of limbs ; under parts, and inner side of limbs pale yellow ; tail pale sooty brown ; hands and feet brownish yellow ; ears yellow. The type has faded, and exhibits at present a cream buff animal with a pinkish tinge on the 74 GALAGO upper parts, and with a brown head and pale sooty brown tail. The ears are very large, and yellow in their dried state. The orbits are the same in color as the rest of the face, but other examples have black orbital rings. This style was named conspicillatus by Geoffroy. G. moholi Smith, is the same as the present species and the name must become a synonym. The type is in the British Museum Collection and is in a faded condition. My description taken from it reads as follows.

This appears to be a well marked, long tailed, blue gray species found in the valley of the White Nile, southward to the west of the Victoria Nyanza, and to Mashonaland up to an elevation of 5,000 feet. Eight specimens are in the British Museum Collection ; from Goz Abu Guma on the White Nile north of Khartoum, Mashonaland at Mazae 5,000 feet elevation, and South Western Ankole, west of the Victoria Nyanza at an altitude of 5,000 feet. It seems impossible to discover any differences to separate these specimens. The skins with one excep¬ tion closely resemble each other; the exception being the one from Goz Abu Guma, which is an ecru drab above, but others from the same locality are the usual blue gray, and for lack of any evidence to the contrary, we must attribute this difference to an individual peculiarity, or to season, as it was taken in April, the blue ones in November. More material and more knowledge of the seasonal changes, are neces¬ sary before the value of many specific differences, so considered, can be fully ascertained. The skulls vary considerably in size, but this difference is probably caused by age or sex. In the Paris Museum is a specimen, No. 187, which is recorded in the old Catalogue as Galago sennaariensis Type. This is probably the specimen called by Lesson (1. c.) Galago acaciarum var. C. sennaariensis. It is the usual blue gray animal, the specimen faded somewhat in the lapse of years, the blue hue only remaining on top of head and upper back between the shoulders, rest of upper parts and limbs assuming a brownish tint. The tail is darker than the body and is now a reddish brown hue. The ears are large and blackish, the under parts and inner side of limbs whitish, and the skull is in the skin. 76 GALAGO Measurements. Total length, 365 ; tail, 195 , foot, 65.

This is a small animal distinguished by its sooty head. That is, as the type is today, as shown to me in the Berlin Museum ; but Peters in his Reise states, that the under parts are grayish white, ( grau weiss), or yellowish wrhite, ( gelblich weiss). Four specimens in the British Museum from a few miles south of Tete have the under side so colored. It is probable therefore that the type has become discolored by dust, and does not correctly represent the species. Galago pupulus Elliot. Galago pupulus Elliot, Ann. Mag. Nat.

Ex type British Museum. This species belongs to the group having the hind legs more or less cream buff in color. The ears are enormous occupying the entire sides of the head, and the pale yellowish hue of the outer side of the limbs is very conspicuous. In general appearance it is very like G. mossambicus, but the characters of the skull are very different. The species just named is remarkable for its very short rostrum while the present animal has a long rostrum, with slender nasals, of about equal width for their entire length, while those of its relative broaden con¬ siderably at the tip ; the bullse are much longer and narrower and the molar series much larger.

There are only two examples in the British Museum Collection, the second one being lighter on back and rump, this apparently on account of the old hair not having been yet shed, as the head and upper part of the back are dark like the type. Bates records (1. c.) that the Nsoe uses neither hollow trees nor old squirrel’s nests for a hiding place in the daytime. They are found sleeping in bunches of as many as a half dozen, clinging with their arms around each other’s bodies and around the branch of a tree. A shrill squeaking or chirping often heard at night among the tree tops of the forest, is referred by the natives to the Nscb. They say that this noise is heard oftener near morning and that then the father is calling together the rest of the company, to gather them into a huddle for the daytime.

Genl. Char. Skull of type has only the frontal bone, orbits and rostrum remaining; but these portions show considerable differences from the skull of G. elegantulus with which species this one has been united by some writers. These differences may be expressed as follows. The width between the orbits is much greater ; the nasals are narrower, and the rostrum anteriorly much more slender and narrower ; the frontal from the parietal suture to nasals is shorter ; the posterior end of nasals is rounded instead of pointed; first upper molar is smaller and the third larger; the bony palate from the center of the arch is longer, and the width throughout its length much less, causing the teeth to lie more on a straight line and not to flare outward, as is the case with the tooth rows of G. elegantulus ; the bony ring of the orbits is much wider. Color. Head, neck, and upper parts bright russet ; dorsal streak burnt umber; outer side of arms mummy brown; outer side of legs GALAGO 81 Prout’s brown; under parts of body, and inner side of limbs yellow¬ ish white, the tips of the hairs being that color ; hands like arms ; feet like legs; tail at base mars brown, remainder bistre with whitish tips. Ex type British Museum. Measurements. About the size of G. elegantulus. Skull: length of frontal, 19 ; width between orbits, 5 ; length of nasals, 12 ; width of rostrum above canines, 10 ; palatal length, 18 ; width of palate between last molars, 14; length of tooth row, 13. Ex type British Museum. The type, from which the above description and measurements were taken, is a very much darker and altogether a differently colored animal than G. elegantulus, and can be recognized at a glance. The differences in color and in the dimensions of the skull above given would seem to almost entitle this form to a separate specific rank. Du Chaillu states (1. c.) this species is called Aboli by the natives. It lives in the forest retiring by day to holes in the trees, coming out at night in search of food, which consists of fruit and insects. The male and female generally dwell together. “I kept one for some time and it throve well, being very fond of cockroaches, bananas and corn.” It is found in the mountains of the interior near the equator. 82 HEM I GAL A GO GENUS 4.

Peters gave a figure of the head, in his text, and a plate by Wolf of a Galago in his paper published in 1863 (1. c.) under the name of Galago demidoffi, but in 1876, (1. c.) decided his example was not that species, and named it Otolicnus pusillus. The plate exhibits an animal very like H. demidoffi, with some slight differences, but these may possibly arise from faulty coloring. The only differences stated by Peters in the later paper to separate his example from H. demi¬ doffi are its shorter ears and smaller size. No dimensions are in this paper, but they are given in the earlier one. Measurements in the Proceedings of the Zoological Society, (1. c.) are as follows: “total length, 2" 2"', tail 3" V", head 1" 1"', arms 1" 5"', legs 2" 6'", thigh 8, tibia 10, foot and tarsus 1".” 84 HEMIGALAGO There is an error here as the head and t3.il 3re made to measure separately, nearly twice the total length. I examined the type in the Berlin Museum. It is a baby and presents no characters to separate it from H. demidoffi. Bates (1. c.) states that the “little djam is similarly found asleep, three or four huddled together in old nests of the squirrel osen. Some people have told me that the little Lemurs make their own nests, but it seems more likely that these are only old squirrel’s nests. An djam that I kept alive once for several days made a chirping noise at night, as shrill as that of a cricket. In grasping anything with its hind hand, the clawed finger was always folded in the palm, under and not over the thing it grasped.” Hemigalago demidoffi poensis (Thomas).

This type is in a good state of preservation, and as yet has probably only slightly faded. There is no real gray hue on the upper parts, the plumbeous of the base of the hairs, when showing through on throat and under parts, alone giving an indication of a gray hue.

Head round ; face furred ; eyes large ; approximate ; ears mem¬ branaceous, projecting beyond the fur; hind limbs longer than the fore limbs ; foot elongate ; nails flat, except that of second finger which is pointed ; tail longer than body. Skull : mastoid region not inflated ; inner upper incisor larger than outer ; last molar smaller than the first, with one internal and one external cusp ; inner hind cusp of molars small, or absent; palate extending beyond last molar. The Mouse Lemurs are small animals with tails as long or longer than the body. The head is round, with large eyes situated close to¬ gether, and the ears which are thin, stand out beyond the fur. The legs are longer than the arms, and the foot is very long, the astralagus, or heel bone, being remarkably elongate. The nails are flat except that of the second finger which is pointed. In their habits these animals are nocturnal, and during the dry season some species become torpid, sleeping all the time. They are only found on the island of Madagascar. During the summer a large amount of fat is deposited on portions of the body at the root of the tail, enlarging this part greatly, and the creature is sustained during the period of hibernation by absorbing this unique store of food ; resembling in this respect the Bears when they hibernate. 88 CH1R0G ALE LITERATURE OF THE SPECIES. 1812. E. Geoffroy Saint-Hilaire, in Annales du Museum d’Histoire Naturelle, Paris. In this paper the Author reproduces drawings of three Lemurs by Commergon, reduced two thirds, upon which he establishes the genus Cheirogaleus ( !) and gives to the three figures the names according to their respective size of C. major, C. medius, and C. minor. It is not known what became of Commergon’ s types ; they probably were not preserved. They are not now in the Paris Museum, but there is a specimen there marked C. major Geoff., Type, so he must have selected it to represent the species he called by that name. C. medius is now in the genus Altililemur, and C. minor is a Microcebus, and is the same as M. murinus (Miller). 1828. E. Geoffroy Saint-Hilaire, Cours de I’Histoire Naturelle des Mammiferes. The Author here describes as Cheirogaleus ( !) milii, the ani¬ mal figured by Commergon to which he had previously given the name of C. major. 1833. Sir A. Smith, in South African Quarterly Journal. C. major is here redescribed as C. typicus. 1840. R. P. Lesson, Species des Mammiferes Bimanes et Quadru- manes. Cheirogale major is here called Cebugale commersonii. 1843. /. E. Gray, in List of Specimens of Mammalia in the British Museum. Two species are here included in the genus Cheirogaleus ( !) C. smithii = Microcebus murinus, and C. typicus = C. major, 1854. P. Gervais, Histoire Naturelle des Mammiferes. Three species are here given of Cheirogale, only one of which belongs to the genus, viz., C. milii = C.major, while C. furcifer and C. murinus both belong to the genus Microcebus. 1855. Wagner, Schreber, Die Sdugthiere in Abbildungen der Natur mit B eschreibungen. Various species are here included in Cheirogale, not all of which belong to the genus; C. milii = C. major Geoff., C. typicus = C. major ; the others should be included in the genera Myoxicebus and Microcebus, viz., C. cinereus = Myoxicebus griseus ; C. olivaceus = Myoxicebus olivaceus ; C. furcifer = Microcebus furcifer; and C. smithii = Microcebus murinus. CHIROGALE 89 1856. Giebel, Die Sdugethiere. Like the Author just preceding, this Writer unites in this work with Chirogale, species of other genera: C. milii and C. typicus = C. major; C. furcifer is Microcebus furcifer; C. griseus is a Microcebus; C. smithii = Microcebus murinus; and C. olivaceus = Myoxicebus olivaceus. 1863. /. E. Gray, in Proceedings of the Zoological Society of London. In this review of the Lemurim: the Author includes in the genus ‘Cheirogaleus (!)’ three species, C. milii, and C. typicus both of which = Chirogale major Geoff roy, and C. smithii = Microcebus murinus (Miller). 1864. St. G. Mivart, in Proceedings of the Zoological Society of London. In this elaborate paper on the crania and dentition of the Lemurhxe only two species of the genus Cheirogale are given : C. milii — C. major, and C. typicus = C. major. In the arrangement of the species, however, C. typicus = C. major is erroneously placed in the genus Microcebus. 1867. St. G. Mivart, in Proceedings of the Zoological Society of London. In this paper the Author endeavors to decide upon the character separating the genera Chirogale and Microcebus, and concludes that it will be possible (and perhaps even useful) still to retain, provisionally at least the distinction between them, though reposing mainly if not exclusively on a few cranial and dental characters. Yet in dividing the species he places furcifer and coquereli both of which belong to Microcebus, with C. milii — C. major, as two of the three species he allots to Chirogale. 1868. Grandidier, in Comptes Rendus. C. major is redescribed as C. adipicaudatus. 1870. Grandidier, in Revue et Magasin de Zoologie. Chirogale crossleyi first described. /. E. Gray, Catalogue of Monkeys, Lemurs and Fruit-eating Bats, in British Museum. This is mainly a repetition of the review of the Lemurim: given in the proceedings of the Zoological Society of London in 1863. Three species are included in Cheirogaleus (!), C. milii = C. major; C. typicus = C. major; and C. smithii 90 CHI ROG ALE = Microcebus murinus. In the appendix to the Catalogue a new genus Azema is created for the species last named, but which is quite uncalled for. 1871. A. Milne-Edwards, in Revue Scientihque. In his “L’Ordre des Lemuriens,” this Author places the genera Chirogale, Microcebus, and Galago in the family Galagince, as a section of Microtarses, and decides that Microcebus and ChiroGx\le, cannot be separated generically. 1872. /. E. Gray, in Proceedings of the Zoological Society of London. A new generic name, Opolemur is here proposed for Chirogale milii — C. major, which was already the type of Cheirogaleus ( !) Geoff. 1873. St. G. Mivart, in Proceedings of the Zoological Society of London. In this paper the zoological rank of Chirogale and its species is discussed. Following the opinion of Prof. A. Milne-Edwards which is apparently here adopted, he considers Chirogale and Microcebus the same generically, and that C. smithii, minor, myoxinus, gliroides, rufus, and pusillus are the same; that C. milii and typicus are synonymous, and adipic audatus, and major Geoff., are the same as C. milii, and also L. samati Grandidier, is the same as C. (Altililemur) medius Geoff. Gray’s genera of Murilemur, Phanar, Mirza, and Prolemur have no claim to distinctness. 1875. Gunther, in Proceedings of the Zoological Society of London. Chirogale trichotis first described as ‘Cheirogaleus (!)’ TRICHOTIS. 1876. Schlegel, in Museum des Pays-Bas, Simiec. In the genus ‘Cheirogaleus (!)’ only one species is given, which, as now understood, should be included in it; viz., C. milii — C. major Geoff. The others are C. samati = Myoxice- bus medius (Geoff.) ; C. pusillus = Microcebus murinus; and C. myoxinus, also a Microcebus. C. trichotis is also mentioned but no specimen had been seen by the Author. 1894. Porsyth-Major, in Novitates Zoologies. This paper is a review of the genera Chirogale and Microce¬ bus, with critical remarks on the species. Three are recognized as belonging to Chirogale, viz., C. milii = C. major, C. melanotis, and C. trichotis. Six are given to Microcebus, C H I RO G ALE 91 and these will be considered under that genus, and one L. samati Grandidier, = Altililemur medius (E. Geoff.), is placed in Gray’s genus Opolemur. 1894. Forsyth-Major , in Novitates Zoologice. Chirogale melanotis first described. 1896. Forsyth-Major, in Annals and Magazine of Natural History. Chirogale sibreei first described. GEOGRAPHICAL DISTRIBUTION OF THE SPECIES. Five species are here recognized as belonging to the genus Chiro¬ gale, all natives of the Island of Madagascar. It cannot be said that the limits of their dispersion are as yet definitely ascertained, especially of those comparatively lately described, as of these we know little beyond the locality in which they were discovered. The one most fa¬ miliar to Mammalogists, the C. major Geoffroy of this work, C. milii Auct., seems to have a rather extensive range on the Island, and is found from Pasandava on the north west coast to Tullare in the south, and on the east coast from Fort Dauphin in the south east, and in Betsileo Province in the lower wooded region, to Tamatave in the north east, and also according to Shaw in Central Madagascar. C. melanotis has been obtained at Vohemar on the north east coast, and C. sibreei was taken at Ankeramadinika one day’s journey east of Antananarivo the capital, but the extent of the range of neither is known. C. crossleyi was procured by Grandidier in the forest of Antsianak, and C. trichotis was found by Mr. Crossley between Tamatave on the north east coast and Morondava on the west coast, but we have no knowledge of the limits within which the ranges of these two species are restricted. It is not improbable, however, that they may have a considerable dispersion in Central Madagascar. KEY TO THE SPECIES. A. Size moderately large ; ears without tufts. a.

Eastern coast of Madagascar; Fort Dauphin to Tamatave; also in the lower wooded regions of Betsileo Province; and on the west coast from Tullare to Pasandava, Central Madagascar. (Shaw). Genl. Char. Nose rather broad; ears moderate, sparsely haired; braincase moderately arched ; orbits large ; palate extending beyond last molars with rather large posterior perforations ; bullae moderately large ; first premolar larger than second ; upper inner incisors broad, flat at tips. The type of C. major Geoffroy is in the Paris Museum and is identical with his C. milii, and as the first name was published fourteen years before the latter, it will of course take precedence, and milii, by which appellation the species has been so long known, must become a synonym. The type is in very good condition and may be described as follows : orbital ring blackish brown ; whitish spot between eyes ; no facial streaks ; face, top and sides of head, and upper part of body to rump, and the tail pale reddish brown inclining to a buff ; flanks and outer side of limbs, hands and feet, reddish brown or buff paler than the back; upper lip toward corner of mouth, chin, throat, inner side of limbs and under part of body white. Measurements. Total length, 609.6; tail, 278.5; foot, 51.4. The type of C. milii while faded somewhat, has undergone less change than most of the types of the earlier species in the Paris Mu¬ seum. It is a reddish brown animal with a yellowish white sheen, produced by the tips of the hairs, and with a long dull brownish tail darkest at the tip. The species varies so considerably in color among individuals that the type can only at best give an idea of but one phase of coloring, with which other examples would only agree in part. A general description of the species would be somewhat as follows. Color. Varying considerably among individuals; head and neck brownish gray, sometimes grizzled with silver gray washed with rufous of varying intensity, this color sometimes extending over the entire upper parts ; in other examples the upper parts are ashy brown ; under 94 CHIROGALE parts and inner side of limbs yellowish or whitish yellow ; orbital ring black; nose and face between eyes light gray; hands and feet dark brown ; tail pale rufous with white tip, or ashy brown for entire length. Measurements. Total length, about 580 ; tail, 275. Skull : occipito- nasal length, 56 ; Hensel, 47 ; intertemporal width, 16 ; palatal length, 24 ; zygomatic width, 38 ; median length of nasals, 18 ; width of brain- case, 28 ; length of upper molar series, 19 ; length of mandible, 37 ; length of lower molar series, 20. Cheirogaleus ( !) typicus Smith, is undoubtedly the same as the present species. The type is in the British Museum and the following description is taken from it. Head and upper parts pale rufous, hairs tipped with gray more profusely on the rump and sides ; orbital ring black ; outer side of limbs and the tail like back ; space between eyes and top of nose without hairs, these having slipped off ; entire under parts yellowish. Measurements. Skull : occipito-nasal length, 54 ; zygomatic width, 34 ; intertemporal width, 16 ; median length of nasals, 19 ; width of braincase, 26; length of upper tooth row, 18; length of mandible, 34; length of lower tooth row, 16. Mr. Shaw, (1. c.) had one of this species in captivity and he relates that it lived in a small box, but was allowed to exercise in the room at night. It was nocturnal in its habits, and was brought from the forest on the lower part of the eastern side of Betsileo province. It ran about on all fours, but sat up to eat, holding its food in its hands. He imagined the animal hibernated, for in the winter, (June), after exer¬ cising for several nights, on opening the box one evening, it was found asleep and quite cold. He thought it was dead, but on holding it to the fire and rubbing it, it gradually awoke, and after having been thoroughly warmed it was none the worse in health. This happened several times, and from the fact that the tail became suddenly enlarged, it probably would, if in its native forest, have slept through the winter. It made a nest of leaves and dry grass, scooping a place in it just large enough to contain its body, and carefully covering itself with the loose material. Mr. Shaw considered it rare in Madagascar, for he was only able to obtain this individual, although he kept a man two months in the forest seeking it. Of course its nocturnal habits make its capture more difficult. His animal was easily tamed, and became very affectionate, coming when called by name, and enjoyed being handled.

The color of the tail of the two species is very much the same. Chirogale sibreei Major. Chirogale sibreei F. Major, Ann. Mag. Nat. Hist., 1896, p. 325. Type locality.

Ex type in British Museum. This animal is about the same in size as C. melanotis, and might pass for a gray phase of that species were it not for the naked ears, those of C. melanotis being rather closely haired. The skulls show differences also, the rostral portion of C. sibreei being much narrower, and the nasals more slender. The tooth rows are straighter, not curv¬ ing outward as in C. melanotis.

In this communication intended for a review of the Lemurhxe, the genus Lepilemur (!) (Lepidolemur), was proposed, to contain Microcebus murinus; M. myoxinus; M. furcifer; and Lepidolemur mustelinus; only the last of the species being properly included. 1864.

While the results arrived at will be discussed under the various genera, as they are reached, it is only necessary here to consider the Author’s conclusion regarding the species of Microcebus. Five are recognized: M. myoxi¬ nus; M. smithi; and M. pusillus; the last two = M. murinus (Miller) ; M. typicus = Chirogale major; and M. furcifer. The Author states, however, that owing to the scarcity of materials “I have not attempted to work out the 100 MICROCEBU S species,” and that he does not intend to imply that all those given are distinct, some only having been adopted provisionally on the authority of others. 1867.

In this list, Microcebus murinus is given as Cheirogaleus ( !) smithi Gray, and placed in the genus Lepilemur (!), and comments are made on Microcebus myoxinus Peters, the Author, however, never having seen a specimen. In the Appen¬ dix several genera are proposed for the species of Microce¬ bus as follows : Murilemur for Microcebus murinus ; Phaner for M. furcifer; and Mirza for M. coquereli. All these are quite unnecessary. 1872. /. E. Gray, in Proceedings of the Zoological Society of London. This paper is practically a repetition of a review of the LemuriD/E given in the Catalogue above mentioned, except that whereas the species of Microcebus were in the pre¬ vious publication placed in various genera, here they are in¬ cluded in one Lepilemur ( !) with the addition of L. mus- telinus Geoff., (which is generically distinct from the species of Microcebus), and with the omission of M. myoxinus Peters. The genera Phaner and Mirza are suppressed. 1873. Mivart, in Proceedings of the Zoological Society of London. This is another of the Author’s elaborate papers on the Lemurid.®, in which he raises the entire group to a suborder of the Primates, as Lemuroidea, and gives very cogent and per¬ tinent reasons why they should not be considered as an order. He also considers that Microcebus and Chirogale are gen¬ erically the same, to be known by the latter name, the one first designated. He cites A. Milne-Edwards’ opinion regarding the species of the genus Chirogale with which he apparently con¬ curs; viz., that smithi, minor, myoxinus, gliroides, rufus, and pusillus are all one; that milii, typicus, and adipicaudatus are the same as major Geoffroy ; that samati is medius Geoff., and M I CROCEBU S 101 that coquereli is distinct. With this opinion the present writer agrees, with the exception of myoxinus of which form the material available is not sufficient to prove that it should not be separated from the rest as a distinct species or race. As regards uniting the species of the two genera; the opinion previously expressed by the Author (Proc. Zool. Soc. Lond., 1867, p. 965), “that it will be possible and perhaps even useful to retain, provisionally at least, the distinction between Cheiro- galeus ( !) and Microcebus, though reposing mainly if not exclusively on a few cranial and dental characters,” may not be disregarded. 1876. Schlegel, Museum d’Histoire Naturelle des Pays-Bas, Simice. In this work in the arrangement of the species of Primates Microcebus furcifer is placed in the genus Phaner, and M. coquereli in Mirza, although Gray had abandoned both four years previously. M. major, called milii, and M. murinus called pusillus, with M. myoxinus (nec Peters), = M. murinus, are placed in the genus Cheirogaleus ( !). The genus Microcebus receives no recognition. 1894. Forsyth-Major, in Novitates Zoologicce. This paper is a critical review of the literature and species of Microcebus, Opolemur, and Chirogale. Of Microcebus, the first species is given as M. minor Gray, the murinus Miller being rejected, for the reason that Miller’s plate of L. murinus = L. bicolor Gmel., which is not proven. The others are M. myoxinus, and M. smithi = M. murinus Miller. 1910. Kollmann, M. in Bulletin du Museum National d’Histoire Naturelle, Paris. A paper on the genera Chirogale and Microcebus. The material upon which the Author bases his conclusions is in the Paris Museum, important collections in other National Institu¬ tions having evidently not been examined. Cheirogale is accepted as a genus and a description of it given, but no species mentioned. Microcebus and Opolemur (Altililemur of this work), are considered to be the same, and the following species named: Microcebus samati = Altililemur medius (E. Geoff.), M. minor — M. murinus (Miller). The following forms are regarded as subspecies all in Microcebus. M. minor minor = M. murinus (Miller) ; M. minor griseorufus nov. subsp. = M. murinus (Miller), red phase; M. pusillus myoxi¬ nus = M. myoxinus Peters ; M. pusillus minor smithi = M. 102 MICROCEBUS murinus (Miller) ; and M. minor rufus = M. murinus (Miller). Evidently Miller’s description of murinus was unknown to the Author, as was also the Bibliography of the species of Microcebus, as some are reinstated, e. g. smithi, rufus, which have been long since relegated to the synoptical list. The paper is one apt to lead investigators astray, by the recognition of individual examples not entitled to any distinctive rank, while Microcebus coquereli (Grandidier), the type of which is in the Paris Museum, is not mentioned at all. GEOGRAPHICAL DISTRIBUTION OF THE SPECIES. The members of this genus are all found in the Island of Mada¬ gascar ; some with quite an extensive dispersion, but the range of others has not yet been entirely ascertained. On the west coast from Cape St. Vincent to Tullear on St. Augustine Bay, M. myoxinus is found, and from Cape St. Vincent to Helville on the same coast M. coquereli occurs. M. murinus ranges from Betsileo Province to Fort Dauphin on the south east coast, and northerly from St. Augustine Bay on the south west coast. Its complete range has not yet been de¬ termined. The species with the greatest known range is M. furcifer which goes from Fort Dauphin on the east coast to Mt. Ambre, and then on the west coast to Cape St. Vincent, thus being found through¬ out the northern section of Madagascar. KEY TO THE SPECIES. A. Size small. a. Sides of nose brown . M. murinus. b.

Betsileo Province to Fort Dauphin on the south east coast of Madagascar, and on the south west coast northerly from St. Augustine Bay. The exact limits of the species’ dispersion cannot be said to have yet been definitely ascertained. Color. Two phases, rufous brown or gray. The first has the head rusty brown ; orbital ring and upper lip black ; stripe between eyes and on nose, grayish white ; upper parts of body rufous brown ; dorsal line indistinct; sides of body and outer side of limbs mouse gray washed with rufous brown ; entire under parts and inner side of limbs white, base of hairs plumbeous, this hue often showing on the surface; tail rufous brown like the back, but sometimes much paler ; hands and feet gray. The other phase is mouse gray above, the back washed with rufous, a rufous spot over each eye ; outer side of limbs mouse gray ; entire under parts white; tail pale rufous. Measurements. Total length about 300; tail, 150; foot, 26. Skull: occipito-nasal length, 33; Hensel, 20; zygomatic width, 21; inter¬ temporal width, 16; palatal length, 11; median length of nasals, 8; width of braincase, 17 ; length of upper molar series, 8 ; length of mandible, 19 ; length of lower molar series, 9. MICROCEBUS 105 I have examined probably all the specimens of this species, under the various names given to it, and in its various styles of coloration, contained in all the great Museums of the world, save that in St. Petersburg, and I can find no character by which the examples called murinus, pusillus, smithi, minor, and others given in the above synop¬ tical list, can be separated or distinguished the one from the other. Specimens vary greatly in their coloration even among those belonging to the two phases gray or rufous brown, and there is also an individual variation to be seen among the skulls. Various types are extant, such as smithi Gray, and the specimen that probably served as the type of minor Gray, both in the British Museum; and of gliroides Grandidier in the Paris Museum, and all belong to one or the other phase of the animal called by Miller murinus. It would seem that the confusion in synonomy, and the perplexity arising as to what name examples of this little creature should bear, has been caused by recognizing forms as t , * distinct that really are not, and the difficulty of obtaining a uniformity of opinion among Mammalogists is emphasized by the fact that the specimens in different collections exactly similar, bear separate names. Mr. Shaw, (1. c.) says that this Lemur inhabits a belt of forestland extending from the eastern forest into the heart of Betsileo Province a few miles north of Fianarantsoa, where the species is fairly abundant. It lives in the tops of the highest trees, and makes a nest of dried leaves closely resembling that of a bird. The food consists of fruits and insects, and Mr. Shaw frequently saw those he had in captivity catch the flies that entered their cage for the honey which was placed there. They were fond of moths and butterflies and ate them greedily. They were very shy and wild, and he never succeeded in taming one. Even among themselves they were quarrelsome and fought fiercely, uttering at the same time a cry like a shrill whistle. The teeth though minute are sharp, and they grip so firmly with them it is difficult to make them loosen their hold. They can leap, but they usually go on all fours, and they are very nimble among the branches. They have much strength in the hands and legs, and they would often hang by the feet head downwards, grasp food in the hands and then draw themselves up¬ wards to their former position on their perch. During this movement the tail served as a balance, but was not used for holding on by, for it is in no sense prehensile. The eyes were large and brilliant, and the hands beautifully perfect, with ordinary sized finger nails ; the second toe nail, however, being long and claw-like. 106 M ICROCEBUS Microcebus myoxinus Peters.

Ex type in Berlin Museum. The type of this species is in the Berlin Museum and has evidently faded considerably, for now the sides of the head, lips, entire under parts and inner side of arms are white; upper part of back is whitish brown, and only the dorsal stripe on lower back is reddish brown ; tail ochraceous buff above, yellowish white beneath. It has all the appear¬ ance of having been similar in color to the British Museum specimen above described, but faded by light. This species is about the size of Microcebus murinus and is not unlike that form in its general appearance. In fact so nearly do they resemble each other that I have found, when a Mammalogist had no personal knowledge of M. myoxinus and depended entirely upon MICROCEBUS 107 descriptions, that the name of this species had been given to examples of M. murinus. Is is much more rare in collections than the species just named, which accounts in a measure for its relative being at times compelled to represent it, and they are really so much alike that I could only find one fairly conspicuous external character to separate them, viz., the color of the nose, that member having its side black in the present species, but brown in M. murinus. The type is now practically useless for determining the species, as it does not resemble at all Peters’ published colored figure, nor agree with his description. As to the ultimate standing of M. myoxinus, whether it will be enabled to maintain a distinct specific rank, or will eventually be ascertained to be a race of the longer known form or possibly identical with it, can¬ not be satisfactorily decided at the present time. The acquisition of much additional material to that already existing in collections is imperatively needed before any definite conclusion is reached. Until such a time arrives, it will be necessary to leave them as representatives of distinct species. Microcebus coquereli (Grandidier). Cheirogaleus ( !) coquereli Grandid., Rev. Mag.

Ex type Paris Museum. This is a moderate sized reddish colored Lemur, without any par¬ ticular markings. The skull is highly arched, and with large bullae. This species was obtained, (Schleg. and Pollen, 1. c.) in the north western part of the Island Africaine. It lives in the most impenetrable forests, and makes a nest a foot and a half in diameter, constructed of straw and dead leaves, in which it sleeps during the day, only leaving it towards night to seek its food. Only one specimen was procured, which would seem to show the species was not very abundant, at least in the locality where this example was discovered. Microcebus furcifer (Blainville) .

Color. Upper parts reddish gray, brighter and more reddish on head and neck ; outer side of limbs dark rufous, almost chestnut on the arms ; throat pale rufous ; chin and rest of under parts yellowish ; a black stripe from lower part of back to crown of head where it bifurcates, each branch leaning towards inner side of ear and ending over the eye; hands and feet dark brown; tail bushy, dark reddish brown with black tip.

This pretty little species, according to Schlegel and Pollen, (1. c.) is found in numbers in the forests in the western part of Madagascar. It also dwells in the eastern part whence M. Goudot sent an example to the Paris Museum. Towards evening it leaves its lodging where it had slept during the entire day. In choosing this it prefers a hole in a tree which has two openings. Often such places are the dwellings of bees, and in that case, the Walouvy, the name the animal bears in the country, separates the hive of the insects from his own nest by a small bunch of straw or dried leaves. The natives pretend that it prefers the society of the bees to rob the honey of which it is very fond. It is much more nimble and agile than the ordinary Lemur, and its leaps are wonderful. Its cry, continually uttered during the night, is very piercing and resembles the syllables ka-ka-ka-ka, similar to the cry of the guinea fowl. 110 MIXOCEBU S GENUS MIXOCEBUS. THE HATTOCK.

The species included here in this genus have been usually placed in Opolemur Gray, which had for its type and only species Cheirogaleus ( !) major E. Geoff roy. There was, indeed, at the time Gray instituted his genus another described species, C. crossleyi Grandidier, which should have been included, but it was evidently unknown to Gray, as he makes no mention of it, and for him Opolemur ( !) was a mono¬ typical genus. Unfortunately for the scientific standing of Gray’s genus, E. Geoffroy had proposed in 1812 for his milii, previously named major, the genus Cheirogaleus ( !) and this fact was per¬ fectly well known to Gray, who gives Cheirogaleus ( !) milii Geoff., as one of the species in his Catalogue of Monkeys, Lemurs, etc., p. 77. In establishing the genus Opolemur ( !), Gray, as was frequently cus¬ tomary with him, ignored the writings of previous authors, and here adopted for his type a species already the type of another described genus. This procedure deprives Opolemur (!) of all scientific stand¬ ing, and reduces the term to a pure synonym of Cheirogaleus ( !) Geoff., and its farther employment as a generic name is prohibited. This leaves the two species C. samati = A. medius, and C. thomasi without a genus, and I propose therefore for them the generic term Altililemur, with A. medius (E. Geoff.), as its type. Only two species of Altililemur are known ; the type just named, and thomasi Major, both heretofore placed in Opolemur ( !), although that term was applied to species possessing different generic characters from those exhibited by the forms now placed under the newly created name. *Altilis. Fatted or Fattening, alluding to the often enlarged base of tail. 112 ALT I LI LEM U R LITERATURE OF THE SPECIES. 1812. E. Geoffroy St. Hilaire, in Annales du Museum d’Histoire Naturelle, Paris. A drawing by Commergon was reproduced in this publication and given the name Cheirogaleus (!) medius. A specimen in the Paris Museum was identified by Grandidier as Geoffroy’s species, and its locality given as Bourbon, Madagascar. 1868. Grandidier, in Revue et Magazin de Zoologie. Altililemur medius (Geoff.), redescribed as C. samati, and by this latter name the species is universally known. 1894. Forsyth Major, in Novitates Zoologicce. Altililemur thomasi is described for the first time as Opole- mur ( !) thomasi. GEOGRAPHICAL DISTRIBUTION OF THE SPECIES. The two known species of Altililemur are both natives of Mada¬ gascar. They are fairly large animals with tails nearly as long as the head and body. The base of the tail becomes very large by laying on of fat before the creatures hibernate, and it is on this they subsist: during the period they remain in a dormant condition. Their range on the Island of Madagascar, so far as known, is very restricted, A. medius having been found only at Bourbon on the west coast, and A. thomasi at Fort Dauphin on the south east coast. Both species are rare in collections. KEY TO THE SPECIES. A. Black ring around eyes separated by a white stripe. a. Tail above dark gray washed with ferruginous. . . .A. medius. b.

The ticket on the specimen states that the species is the “Chirogaleus medius (Geoff.), C. samati (Grand.), Type,” from which I infer it is Gran- didier’s type and not Geoffroy’s. The example was procured by Gran- didier at Bourbon, West coast of Madagascar. Mivart states, (1. c.) that Prof. A. Milne-Edwards informed him that C. samati Grandid., was the same as C. medius E.

Smaller in size than the true Lemurs (genus Lemur ) ; head conical ; ears large, round, hairless ; tail shorter than body ; fourth finger and fourth toe longest; nails keeled, that of the great toe large and flat. Skull : nose long ; no upper incisors as a rule ; canines large with a posterior heel, and internal groove ; no diastema between canine and first premolar; the latter tooth has one exterior cusp only; the next two molars have both an interior and exterior cusp ; the last molar has three cusps ; all the molars have a rudimentary hind cusp largest in last molar ; lower first premolar large, resembling canines, with a proc¬ ess on anterior margin ; last molar with one exterior cusp ; the median molar with one external and one internal cusp. Palate extending to middle of last molar. Mastoids much enlarged and swollen. Sagittal ridge present. Space between orbits, and in front of lacrymal foramen, depressed. Feet only slightly elongate. No os centrale in wrist. This genus was instituted by I. Geoffroy (1. c.) for the reception of his L. mustelinus, at that time the only species belonging to it that was known. Since then others have been discovered and seven are now recognized. Lepidolemur has been thoroughly investigated by St. George Mivart in his excellent paper on the Lemurhxe and its characters plainly given ; and he failed to find that its affinities had any marked relationship with any other genus, although it approximates to Hapalolemur = Myoxicebus, more nearly than to any other. The teeth are peculiar and recall those of Indris. They are arranged in nearly parallel lines, and there are no incisors in the upper jaw. The first lower premolars are large, similar to canines in shape with one external cusp, and the last lower molar has a large fifth cusp. The 116 LEP 1 D 0 LEM UR angle of the mandible is produced downwards as well as backwards. The navicular bone is long and the foot thereby lengthened. The species, like all those of the Lemuridaj, are nocturnal and live in trees, and are agile in their movements. But little is known of their habits, and certain of the species are represented by the unique types in Museums only. The genus is divided into two groups arranged according to size e. g. large or small, the first containing three species, the latter four. When a number of examples have been assembled together, much variation in color is seen to exist among the older forms, but whether an equal diversity will be found on the species more recently described it is impossible to state at present. All the species thus far discovered are natives of Madagascar. LITERATURE OF THE SPECIES. 1851. I. Geoff roy Saint Hilaire, Catalogue des Primates. Premiere Par tie Mammifhes.

Ambre in the north to Fort Dauphin in the south; and in the eastern districts of Betsileo Province, Central Madagascar, L. micro- don is met with. At Fort Dauphin in the southeastern part of the island, L. leucopus was obtained. Passing to the opposite side of Madagascar at Betseko on the northwestern part L. edwardsi was pro¬ cured ; and somewhere in this part, locality not given by its discoverer, L. grandidieri comes ; in the southwestern part from Marinda to Masi- kora, L. ruficaudata ranges, and in the same section at Ambulicata, L. globiceps is found. It will be seen that several of the species are LEPI DOLEMU R 117 limited to one locality, and this is on account of the limited number of examples procured, as all the species obtained by Forsyth-Major save one, L. microdon, were represented by only one specimen. The dis¬ tribution of these, therefore, is still to be ascertained. KEY TO THE SPECIES. A. Size small. a. Feet not white. a. ' “Tail drab color” . L. globiceps. b. ' “General color cinnamon” .

Ex type in Paris Museum. The L. dorsalis Gray, is the same as L. mustelinus. The type is in the collection of the British Museum, and may be described as follows. Top and back of head grizzled grayish brown with an indis¬ tinct dark brown stripe in the middle of the crown ; upper part of body reddish brown ; on the lower back the tips of the hairs have all been worn away leaving only the blue under fur visible ; shoulders and outer side of limbs like the back ; under part of body and inner side of limbs grayish fulvous, the plumbeous under fur showing through in many places ; hands reddish brown, feet paler brown ; tail above bluish gray on basal half, (tips of hairs worn away), pale rufous on apical half, beneath pale rufous. This type specimen is slightly smaller than Geoffroy’s type, and its tail a little longer, but the color of the upper parts and texture of the fur is very like L. mustelinus. The skull of the type of L. dorsalis had been mislaid and I did not see it. Another specimen in the British Museum attributed to L. dorsalis has lost nearly all the reddish tips of the hairs, and is nearly a plum¬ beous color, but gray on head and between the shoulders, while a brown stripe extends from the forehead to the middle of the back. Gray states there is no dorsal stripe, and his type has none, but in these ani¬ mals the absence or presence of a dorsal stripe may be regarded more as an individual than an important specific character, as its depth and distinctness varies greatly among examples. The tail is somewhat darker. I am unable to discover any character by which these speci¬ mens can be separated from L. mustelinus. The skull of this last individual measures as follows: occipito-nasal length, 49; Hensel, 40; zygomatic width, 35 ; intertemporal width, 18 ; palatal length, 17 ; width of braincase, 30; median length of nasals, (broken) ; length of upper molar series, 20 ; mandible wanting. A specimen in the Paris Museum is very red on back, and tail red on basal half, rest dark brown. LEP ID OLEMU R 121 Another example is pale reddish brown on upper parts, the tail buff washed with reddish. There is great variation among individuals. Little is known of the habits of this species, but according to Schlegel and Pollen (1. c.) it resembles in these respects those of M. furcifer, and these two species are often seen together. It is very stupid and lazy, more so than M. griseus, and the natives say they often kill it in the day time with sticks. It will eat flesh. Lepidolemur microdon Major. Lepidolemur microdon F.

Head, back, shoulders, outer side of arms, and front of thighs, chestnut ; lower part of back at rump paler ; blackish brown stripe from crown to middle of back; outer side of legs rufous; in one specimen this part is like the back; in most examples there is a narrow ochraceous stripe from the cheeks to back of neck, but this is only partly shown in the type ; throat and fore neck dark gray ; chest chestnut ; under parts of body and inner side of limbs yellowish gray. The type has lost the tip of the tail, the portion remaining is russet ; but the entire tail taken from other specimens has the basal half chestnut and the remaining portion blackish brown.

There are several mounted specimens of this form in the Paris Museum, all of which, according to the regrettable custom prevailing in that Institution are marked as “types.” Some are greatly faded and show but little of the original coloring, and which one is the real type it is impossible to say. The one described was procured by Grandidier at Morondava, Madagascar, in 1869, and is of course not the true type, but a co-type. The probably real type taken at the same place in 1867 is so faded that but a faint idea of its original coloring can be obtained. The chief difference between this form and L. mustelinus is in the shape and proportion of the skull. Three or four skins, how¬ ever, in the collection in the drawers, still retain the original coloring. Lepilemur ( !) pallidicauda Gray, is the same as L. ruficaudatus. Why Gray should have described it as distinct is difficult to imagine for he states, (1. c.) that, “this animal was sent to us by Mr. Frank of Am¬ sterdam as Lepilemur ( !) ruficaudatus Grandidier,” and then he i LEPIDOLEMU R 123 gives Grandidier’s short description. Surely there was no reason to confer upon the hapless animal a new name. Gray’s description of the male is short and he gives none of the female, merely making a slight reference to the color of the tail. The following description is taken from this female. Head gray, hairs tipped with black; back grayish washed with brown ; a reddish brown (not very distinct), stripe on middle of back ; rump buff or pale fawn ; shoulders and arms red¬ dish brown ; outer side of legs pale gray ; entire under parts and inner side of limbs yellowish white; hands rufous, feet gray; tail above dark brown, beneath basal half yellowish white, remainder pale cinnamon. Measurements of the male’s skull are as follows. Occipito-nasal length, 56; Hensel, 45; zygomatic width, 37; intertemporal width, 17; palatal length, 21 ; width of braincase, 27 ; median length of nasals, 14; length of upper molar series, 21 ; length of mandible, 41 ; length of lower molar series, 23. It will be seen that there is very little difference in the measure¬ ments between this skull and that of the male given above. Lepidolemur edwardsi Major. Lepidolemur edwardsi F.

Ex specimen in Berlin Museum from Vohemar, Madagascar. The type in the Paris Museum is so faded from exposure to the light for more than a century that the original color has disappeared, and a description of the specimen would be useless. In their account of this species Schlegel and Pollen say, by the natives in the northwest part of Madagascar it is known by the name *This figure is badly drawn, or does not represent the skull of M. griseus. It is altogether too broad, especially the muzzle. See Jentink, (1. c.). MY 0 XI CEB US 127 of Bokomboula, and it inhabits the forests of bamboo. They found it several journeys from the coast on the banks of the river Ambassuana. This animal remains during the day asleep among the shoots of the highest bamboos, the back curved, the head placed between the thighs, and the tail covering the back. It is strictly nocturnal in its habits, and does not perceive its enemies nor know of the hunter’s approach. It feeds on the bamboo leaves, which were always found filling the stomach. It is very lazy during the day, but at night exhibits an activity and agility that is incredible. It utters a feeble grunt similar to that of a pig, but much less pronounced. The young are born in De¬ cember or January. A young one kept in captivity lived on bananas and cooked rice, but it only ate the latter when forced by hunger. It had the bad habit of gnawing its tail as monkeys often do in captivity. On pointing a finger at it, it flew into a rage, showed its teeth and uttered sharp grunts. Myoxicebus oliyaceus (I.

Ex type British Museum. This species has been confounded with M. griseus (E. Geoff.), by various writers, and Gray himself thought it might be M. olivaceus (I. Geoff.), though he maintained it was not the same as M. griseus. It is a much larger animal than that species, and the skulls if com- MY 0X1 C EBU S 129 pared would show at once by their great dissimilarity of size, and shape of the muzzle, (one broad and one truncate, the other narrow and pointed), that they represent very distinct species. There are two specimens in the Paris Museum, marked male and female and named M. simus, collected by M. Lentz in the valley of Ambookobe, Madagascar, but which in color, do not resemble Gray’s type of the species. Both examples have the very broad nose and muzzle of M. simus. The following description was taken from the male specimen. Nose between eyes and on sides black; top of head, neck, and between shoulders, reddish chestnut, the hairs tipped with ochraceous ; rest of back, sides of body, outer side of limbs and under parts yellowish gray, tinged with reddish on arms; throat and under side of arms below elbows rusty ; hands reddish ; feet yellowish gray ; tail at base pale red, remainder brownish gray, blackish at tip ; muzzle white ; ears grayish on long hairs. It will be seen that this specimen differs greatly in color from the description of the type of M. griseus given above, and while both examples have characters that would seem to indicate they belonged to Gray’s species, the various differences they exhibit in coloration would show that the form was subject to great diversity in its hues. Mr. Shaw gives an account of one of these broad nosed Lemurs which he had in captivity (1. c.). It was caught in the higher level forest among the bamboos on the eastern side of Betsileo Province. The outwardly inclined teeth in the lower jaw were used as scrapers and not for biting. Besides these nearly all the teeth were serrated and arranged in opposition so as to intersect, and it could bite off easily the young shoots of the bamboo, and mince up a handful of grass blades and stalks, each bite cutting like a pair of scissors. It feeds nearly throughout the entire day, like most grass-eating animals, and for several months this Lemur was kept chained on the lawn, and it rarely ceased from eating the grass from morning until evening. It disliked fruit and could not be induced to touch it although tempted with various kinds growing in the forest, but was very fond of cooked meat and sugar cane ; and through its desire for sugar it was induced to eat cooked rice, which eventually became its chief food. The broad pad on the great toes enabled it to grasp even the smoothest surface firmly. The male’s head was round in shape, the female had a more pointed nose. The cry it uttered was at times like that of a duck, but on other occasions was loud and piercing. 130 LEMUR GENUS LEMUR. TRUE LEMURS. T ?=?. p k=L P *=*. M — = ?6. LEMUR Linn., Syst.

Size. ■ LEMUR 131 enable the animals to grasp the branch of a tree with great tenacity. In size they are about equal to the house cat, and their fur is thick, some¬ times woolly in texture. Not very much is known of their habits in the wild state, but they are not so strictly nocturnal as the species of the other genera of the family, and are seen during the day as well as at night seeking food. They are only found in the Island of Madagascar and the adjacent Comorin Islands. They go in troupes, sometimes of many individuals, are very noisy and live in the forest, one species only, L. catta, frequenting rocky places destitute of trees. They are very agile and their movements are made with great rapidity. Their usual note is a kind of low grunt, but they often utter loud cries. Fruits of various kinds, and insects, bird’s eggs and birds themselves, when they can catch them, furnish their principal means of subsistence. During the heat of the day they sleep, the head placed beneath the arms and the tail coiled about the neck. They walk on the hands and feet, both when on the ground or amid the trees, the tail usually carried high up. Great confusion has existed in the many published articles on the species, mainly from a lack of sufficient material by which a correct judgment could be obtained. Much variability occurs in the coloration, individuals of the same species differing greatly in this respect, and in not a few instances the female has been described as a species distinct from the male. In some cases there is wonderful difference in color between the sexes, and in such cases it is not to be wondered at that the female should have been considered as representing a species, the male of which had not at that time been obtained. To rectify the synonymy given by different writers is no easy task, as they have not always been in accord as to the name of different species, and much confusion has been created by bestowing various names upon the same species. De-' scriptions of these animals by the earlier writers were often so meagre and insufficient that it was difficult, if not impossible, to ascertain what one was intended, and the task was made no easier by the disappear¬ ance of the type from the collection of the Institution in which it was originally deposited. But after an examination of all the types now existing, and a careful study of the collections of these animals in the Museums of the World, the conclusions given in the articles on the various species, deemed worthy of recognition, have been reached. LITERATURE OF THE SPECIES. 1758. Linnceus, Systema Natures. Three species are included in Lemur, only one of which belongs 132 LEMUR to the genus, viz., L. catta. The others are tardigradus , of the genus Loris, and volans included in Galeopithecus. 1762. Brisson, Regnum Animale. Four species of Lemur are here given, under the genus Pro- simia: viz., P. fusca, P. pedibus albus, P . pedibus fulvis, and P. cauda annulis cincta. The first three cannot be determined with any degree of certainty, the fourth, however, is without doubt Lemur catta Linnaeus and must be regarded as the type of Brisson’s genus. 1766. Linnceus, Systema Natures. Beside the species in the former edition of this work, given above, two more are added, L. mongos, and L. macaco. 1774. Schreber, die Sdugthiere in Abbildungen nach der Natur mit Beschreibungen. Various species are given in this work under Lemur, not all of which belong to that genus. L. tardigradus = Loris tardi- gradus; L. mongos (nec Linn.), = L. fulvus E. Geoff., and is mixed in synonymy and plates. L. fulvus and L. rufi- frons are confused together and the synonymy given belongs partly to each, while plate XXXB represents L. fulvus, and XXXIXA has a figure of L. rufifrons. L. macaco Linn., is also confused with L. variegatus (Kerr), and plate XLA represents the former, and XLB the latter, while the synonymy belongs partly to each. L. catta is correctly given. The “Yellow Maucauco” of Pennant is included without any Latin designa¬ tion in the text; but is called on plate XLII, Lemur simia- sciurus. Lemur volans — Galeopithecus volans. A plate of L. albifrons. No. XXXIXD is given. 1777. Erxleben, Systema Regni Animalis.

St. George Mivart, in Proceedings of the Zoological Society of London. An important paper on the crania and dentition of the Le- MURnLE embracing all the genera, with the species of some as then understood, and with definitions of genera and subgenera. Of the genus Lemur a careful specialized description is given of the skull and teeth, and comparisons made with other genera of the Family. The synonymy and description of the genus are given, but a list of the species is omitted. Lemur is placed in the sub¬ family Lemurin^e, followed by Myoxicebus (Hapalolemur) , Microcebus, Cheirogaleus (!), and Lepilemur (!). The conclusion of his investigation may be summed up in his own 136 LEMUR words : “I have been quite unable to detect any cranial or dental characters which would justify a subdivision of the genus Lemur.” He divides the Lemurid^e into four subfamilies with fifteen genera, an arrangement that has not been adopted, as the species of several of the genera, such as Daubentonia, Tarsius, and Nycticebus etc., are considered as possessing characters sufficiently distinctive to make their species repre¬ sentative of independent Families. 1867. St. George Mivart, in Proceedings of the Zoological Society of London. This is a supplementary paper to the one mentioned above, in which the genera Cheirogale and Microcebus are compared and the differences found to be few, but “it will be possible (and perhaps even useful) still to retain, provisionally at least, the distinction between Cheirogaleus (!) and Microcebus, though reposing mainly, if not exclusively on a few cranial and dental characters.” Lepidolemur is also discussed and is con¬ sidered not to have any marked relationship to any other genus. The tarsal structure of these three genera and that of Galago is compared. 1868. Schlegel and Pollen, Recherches sur la Faune de Madagascar.

This volume is a most valuable and authoritative review of the Primates, the Author’s conclusions being founded upon the great collection of these animals in the Leyden Museum, which was doubtfully equalled by that of any other Institution at that time. The opinions expressed therefore are entitled to the greatest respect, and when it may be necessary to disagree with the Author, it will be found generally that new material, obtained since his work was published, has shed a clearer light upon doubtful points, that could not be decided satisfactorily when he was writing his review. Of the genus Lemur he recognizes comparatively few species, and divides them into two Sections with subdivisions added. These Sections are I, with the tail having more or less a uniform coloration such as grayish, brownish or rufous, the apical half being often brown or blackish, and II, with the tail ringed with black and white. The first is again divided into A, with those species having the nose black, and B, with those having the nose covered with white hairs. A has four subdivisions, a containing animals of large size with tails nearly as long as the body, chin and upper part of throat naked, fur thick and woolly, varied chiefly with black and white and reddish brown, and ears hidden by the long hairs on each of their sides, color very variable but not dependent on age of animal. This division has L. variegatus Kerr. /?. Pelage of male black, that of female, more or less bright red. In this is included L. macaco Linn. v. Front and crown more or less black with a large whitish spot on each side of the brow ; ears naked at edge, remainder covered with short hairs. Color gray tinged sometimes with brown, or fawn or red; the four hands of the same hue as the dominant color, or verging to red. Above reddish or grayish white. Tail at base above, and hind part of thighs of a bright red, more 138 LEMUR or less deep in hue. Apical half of tail ordinarily black. Individual modifications of these hues often occur, and local differences in the style of coloration are more or less apparent as if indicating subspecies. Two species are placed in this division L. collaris E. Geoff., — L. fulvus E. Geoff., and L. c. rufus — L. rufus E. Geoff. 8 Head white to the vertex , with L. albifrons. e. Ears rather small, thickly covered with, and hidden in the fur. Color of pelage brownish red ticketed with black, the tail more or less black. Under parts either red, or yellowish or whitish.

I. Forsyth-Major , in Proceedings of the Zoological Society of London. An important contribution dealing with the os planum and lachrymal in Lemurs and Monkeys. The conclusion is, that in those Lemurid^e which have a large lachrymal the os planum is reduced and vice versa. The following points in existing species are insisted upon when there is a “great facial expansion of the lachrymal and particularly its exten¬ sion beyond the fossa lachrymalis.” 1. “It is scarcely more frequent in Lemurs than in the LEMUR 139 higher groups ; the greatest reduction of the lachrymal occurs precisely within the Prosimiae. 2. It is at its minimum in young individuals. 3. The genera of each group in which this character is presented have certainly no closer relationship with those of another group. 4. It can always be traced back to an elongation of the facial cranium, necessitated by a more powerful dentition. This extension of the lachrymal, is, in the Lemurs as well as in the Monkeys, not a primitive condition, but an extreme specialization. GEOGRAPHICAL DISTRIBUTION OF THE SPECIES AND SUBSPECIES. The species of the genus Lemur are found on the Island of Madagascar and some of the small neighboring islands ; Madagas¬ car, as would naturally be inferred on account of its large size, containing most all of the species, if not indeed all of them, and this island may be regarded as the original home of the genus. On the northern portion of Madagascar from the east to the west coast, from the mouth of the river Antamba and the environs of the Bay of Mazamba to Bombetok (Schlegel), and also on the north eastern coast, (Schlegel, limits not defined), L. fulvus is found. On the same coast from Vohemar to the Bay de Diego is the range of L. coronatus, and from Adampone to Cape Masoala L. variegatus is met with. Still on the north east coast from the Bay of Antongil to Masindrano we have L. albifrons and L. v. ruber; and from Teneriffe to Fort Dauphin in the south L. rubriventer is found. In the rocky lands of the south and south west portion of Betsileo Province, and also in the Province of Anossi, is the home of L. catta ; and in southern Madagascar from the River Tsidsibon to the River Mangonka, L. rufus has its range. On the north west coast from Baly to Marinda, and also on the neighboring islands of Anjuan (Johanna), Comoro, Nossi-be, and Mohilla, L. mongos is found; and from Cape Ambre to Ifassy L. nigerrimus ranges; while from Ifassy to Manaharana are the limits of L. macaco. From Baly to Cape St. Vincent L. rufifrons occurs; and from some portion of Madagascar as given by E. Geoffroy, locality not stated, and also from the Island of Mayotte, L. nigrifrons is found. For L. cinereicefs Milne-Edwards and Grandidier, no lo¬ cality has been given, those authors having simply published a figure of the species without any description. 140 LEMUR The ranges of the recognized forms of Lemur here given may probably be more extensive than is known at present, at least for some of them, but further exploration of Madagascar, especially in the interior will be necessary to decide positively any doubts now held upon this point. The limits given have been ascertained from specimens in different Museums having particular localities attached to them, and also from various maps placed in the collection of Lemurs in the Paris Museum, prepared, presumably, under the direction and supervision of Grandidier and A. Milne-Edwards. It is greatly to be regretted that the text for the Lemurs in the Histoire Naturelle de Madagascar of the authors above named, was never published, for it would have undoubt¬ edly have thrown much light upon the variation, distribution and habits of these singular animals. The plates do indeed give in a restricted manner, some idea of how Lemurs vary, but it would require more than one volume of illustrations to exhibit the often extraordinary differ¬ ences shown by these animals in the hues of their coats, both between individuals, and also at times between the sexes of the same species. This could only be properly demonstrated in the text of a volume de¬ voted solely to this group. In a work like the present, lack of space only permits that the attention be called to this fact and the inclusion, in the articles on the species, of the descriptions of a few striking instances, which of necessity only give an inadequate idea of the condi¬ tions existing.

The type of L. flavifrons is in the British Museum, and the follow¬ ing is a description of it. Pale yellowish band across forehead; nose bright rufous ; top of head, body above, and beneath ears rufous, dorsal line darkest ; rump paler, more reddish ; shoulders yellowish ; outer side of limbs rufous like head ; hands and feet dark rufous ; chin and throat whitish ; inner side of limbs, neck and body beneath yellowish, tail rufous. A second specimen also a female, is very much darker in color, being bright chestnut on head and body, dorsal region and hands blackish chestnut, feet and tail rufous. While having a general resemblance to each other, these two examples differ greatly in depth and shade of color. Schlegel in his monograph of the Lemurs was the first to call atten¬ tion to the fact that it was not the animal that was most common in collections, and of a rather large size which should bear the name of mongoz given by Linnaeus, but a smaller form distinguished in the male by rufous patches beneath the ears, extending sometimes on to the throat, and with a whitish face and nose. Later Forsyth-Major in the Proc. Zool. Soc. Lond., 1901, p. 249, published a paper in which he showed very conclusively that the wrong animal had been accorded the Linnaean name of mongoz, and agreed with Schlegel that the smaller rufous-cheeked animal should rightfully bear the appellation. The female is very similar to the male in general appearance, but lacks the rufous coloring ; and the patches on the side of head and throat, called whiskers by Schlegel, are white, and she is rather lighter on the under side of the body. Besides Madagascar, this species is a native of the islands of Anjuan, (Johanna), Mohilla, and Nossi-be. According to Schlegel and Pollen, (1. c.) “this species inhabits the forests which extend from the bay of Diego-Juarez to the bay of Bam- betoc, also the forest of Loncoube in the island of Nossi-be.” The animals go in troupes and keep to the highest trees. Ordinarily they can be seen towards evening, and then their voices are head in loud cries, for at that time they are exceedingly noisy. Sometimes when danger approaches these cries are changed to growling. Their agility in leap- 144 LEMUR ing from tree to tree is wonderful and can hardly be followed with the eyes, and it is easier to kill a bird on the wing than one of these animals when leaping. They have the habit when pursued of dropping suddenly from a lofty tree into the bushes, and the hunter thinking the indi¬ vidual to be dead, is soon undeceived by seeing it quickly seeking another tree a considerable distance away, and this makes following them difficult. When raised in captivity from a very youthful age, it is gentle and friendly. It will eat all kinds of fruits, and is especially fond of bananas, upon which it chiefly subsists in the wild state. It is also fond of bird’s brains, which, after breaking the skull with its teeth, are sucked into the mouth, but it does not eat the bird. The inhabit¬ ants of Nossi-falie will not permit this animal to be introduced there, as they contend that its presence would be a profanation of their so- called sacred island. Lemur coronatus Gray.

The supposed type of L. nigrifrons in the Paris Museum, has the black spot at the root of the tail above, characteristic of the island form named by Schlegel mayottensis. This spot is generally very conspic¬ uous and causes the specimens from Mayotte to be readily recognized. Another peculiarity is the absence of spots over the eyes, which is observable in another “type” in the Paris Museum, although the one described has these marks ; the muzzle is also broad and inflated, quite different in shape from the rather pointed muzzle of L. fulvus; and the third upper premolar and the first and second upper molars are larger. There is much individual variation in color, as in the other species, and some are all yellowish gray with all the top of the head black, and no rufous showing. It would seem that the characters men¬ tioned are sufficient to give this form a distinct rank, and that it was an error to regard it as a synonym of L. fulvus. Between the Paris Museum examples and those from Mayotte Island there are no grounds for separation, and it may be, Geoffroy’s specimens came originally from Mayotte Island, as it is not likely, at the time he wrote, that a discrimination of the islands would be made, but all material from that quarter would be labelled Madagascar. Messrs. Schlegel and Pollen state that they discovered this species Volume I Plate 6 Lemur fulvus LEMUR 147 during their visit to the island of Mayotte, situated in the western part of the bay of Gongonie. It goes in bands of from six to twenty individuals in the primeval forests of the island. They are seen both by day as well as at night, keeping mostly to the trees, but descending occasionally to the ground to look for fallen fruit. At the setting of the sun they utter their plaintive cries in unison. When pursued by dogs they seek the highest trees, intently watching their enemy and growling. It is only when they see the hunter that the entire band takes flight, seeking the depth of the forest where it is exceedingly difficult to follow and shoot them. When wounded it defends itself against the dogs with great fury, and it has been seen to leap upon the back of one and bite its ears and neck. At Mayotte in hunting this Lemur, a cur dog is used, which on perceiving one of the animals keeps up a continual barking, jumping at the same time against the tree on which the Lemur is. The latter pays more attention to the dog than to the hunter, and is easily approached and shot. This species is fond of wild dates, and makes long journeys in search of them. The flesh of this Lemur is excellent, and tastes like that of the Hare. Lemur fulvus E. Geoff roy. Lemur fulvus E. Geoff., Ann. Mus. Hist. Nat. Paris, XIX, 1812, p. 161, No. 9; Smith, Proc. Zool.

Its nose is neither black nor white, LEMUR 149 and in the rufous coloring of the cheeks, sides of the neck and throat it resembles L. mongos Linn., but its black hands and feet separate it from that species, as do also its dusky under parts. This is not Gray’s Prosimia collaris which = L. mongos Linn., nor does it seem to agree with any described species ; and the thought arises, can it be a hybrid born in the Zoological Gardens, as it seems to have resemblance to more than one species, its nose neither black nor white keeping it out of both groups as arranged in the key of the species. There are great variations in color and in head markings among individuals of this species, and this fact has been the cause of the multiplication of names, and confusion in the synonymy. It is the common Lemur called L. mongos generally by authors and attributed to Linnaeus. It is however a larger animal than the true L. mongos Linn., and has a black face and nose which the other species never has. Attention has been called to the error, so universally committed by authors, by both Schlegel and Major as mentioned in the article on L. mongos Linn. The names fulvus and collaris were bestowed upon this species by E. Geoffroy St. Hilaire (1. c.) and both published on the same page, but as fulvus comes first, it must replace the somewhat better known collaris. The types of both L. fulvus and L. collaris have disappeared from the collection in the Paris Museum, but there is an example marked L. collaris E. Geoff., and which was figured in the Histoire Naturelle de Madagascar by Milne-Edwards and Grandidier. This animal died in the menagerie of M. Polito, and was given by him to the Museum in 1828. While therefore, it cannot be any specimen examined by Geoffroy when he named the species, it is probable that it represents fairly enough Geoffroy’s form so far as can be determined by his meagre description. This Paris Museum specimen may be described as follows : top of head and back of neck blackish maroon ; entire upper parts and outer side of limbs reddish brown ; dorsal line from neck broadening on rump, dark reddish brown ; a reddish brown spot over each eye ; cheeks and large patch between ears extending to throat bright rufous ; throat, under part of body and inner side of limbs pale yellow, (probably faded) ; hands and feet rufous ; wrists and ankles bright rufous ; tail chestnut. When considering examples of a species so varying in color as the present, it is not to be wondered that writers with insufficient material at their command should have been induced to describe some of their specimens as distinct species, but it is not always easy, when such examples are no longer accessible for examination, to accurately define what species they really belong to. And this has been one of the dififi- 150 LEMUR culties in the synonymy of the present species. The descriptions are often meagre and insufficient, and the types no longer existing there was little left to assist a correct decision to be reached. Some types remain such as L. xanthomystax Gray, and L. melanocephalus Gray, both of which are undoubtedly the same as L. fulvus. These are both in the British Museum and may be described as follows : L. xanthomystax Gray, (1. c.). Head and back of neck black; black line between eyes ; nose black ; dark buff spot tinged with rufous over each eye ; large bright rufous spot on each side of throat ; fur of body and limbs rufous gray, hairs black tipped ; dorsal line dark reddish brown ; under part of body pale rufous ; hands and feet rufous ; basal portion of tail dark brown, remainder blackish. Ex type in British Museum. Measurements. Skull : occipito-nasal length, 90 ; Hensel, 77 ; inter¬ temporal width, 31 ; zygomatic width, 54; median length of nasals, 22 ; length of upper molar series, 30 ; length of mandible, 62 ; length of lower molar series, 27. L. melanocephalus Gray, (1. c.). Top of head with a narrow line extending over the ears to the occiput ; forehead, face and nose black ; upper part of body grizzled chestnut and black; outside of arms iron gray ; outer side of legs brownish gray, chin and throat pale yellowish ; outer side of limbs, and body beneath buffy ; hands dark brown ; feet bright rufous ; tail chestnut with black tips to the hairs on basal half, but nearly all black on apical half. Ex type British Museum. It will thus be seen from the above descriptions that while the general resemblance is the same, yet there are various differences in coloration sufficient to mislead unless the species’ tendency to exhibit individual variations was not known nor understood. The black nose will, however, always distinguish L. fulvus from L. mongos, as well as its larger size, but neither of these characters are sufficient to separate it from the next species with which it is more closely allied, at least so far as coloration is concerned.

Ex co-type in Leyden Museum. Skull in the specimen. This example is stated to be “un des types du Lemur rufus E. Geoff.” It is, as the description shows, of a bright rufous color, quite different in appearance from all the other Lemurs. It came from the Paris Museum in 1815. The type of Lemur rufus Geoffroy, is in the Paris Museum but in a very dilapidated condition. In fact, excepting the hind neck and dorsal region, there is very little color remaining, and the specimen or co-type in the Leyden Museum is in a much better state. As near as it can be given, the following is a description of this type. Color. Nose on top and on sides black ; a narrow line from occiput over center of head broadening out on forehead and between eyes black, 154 LEMUR tinged with brown ; on each side of this on top of head, and on sides in front of ears white or yellowish white; beneath ears, hind neck, and upper parts of body, and shoulders, deep ochraceous buff with a red¬ dish tinge ; arms much discolored, but seem to be paler than back until halfway on forearms where they are like the upper parts to wrists and hands; outer side of legs and flanks pale golden yellow; feet so dis¬ colored with the dust of years, nearly a century, that it is impossible to tell with certainty what was the original color, but from one or two places that show a little color, it would seem to have been like that on the back; under parts and inner side of limbs pale golden yellow, possibly, originally a rich golden yellow ; tail mostly denuded of fur, and what remains is black with dust, but probably in the life of the animal it was like the back, reddish and ochraceous buff.

Eastern coast of Madagascar from Masindrano on the south to Bay of Antongil on the north. Genl. Char. Greater part of head white. Color. Male. Forehead, cheeks, temples, back of head and ears white ; face from above eyes, and nose black ; upper part of body, and outer side of limbs dark brown, each hair tipped with bright pale rufous, giving the fur a speckled appearance; entire under parts, and inner side of limbs whitish gray; hands and feet like outer side of limbs ; basal half of tail like the back, apical half black. Female. Paler than the male, and the white seen on the head of the male, is dark gray on the female. Measurements. Similar in size to L. fulvus. Skull: occipito- nasal length, 84; Hensel, 7 5 ; zygomatic width, 49; intertemporal width, 27; median length of nasals, 31; palatal length, 37; length of upper molar series, 28 ; width of braincase, 38 ; length of mandible, 57 ; length of lower molar series, 31. This is a large Lemur, easily distinguished from all others by hav¬ ing the head from the eyes to behind the ears, and the cheeks white. The type, if it ever was in the Paris Museum, has disappeared. On plate XIII of the Cimelia Physica J. F. Miller has figured an animal with a heart shaped white spot on the forehead, and described by Shaw as having the “upper part of the neck and back, hind part of the thighs and tail black; the under part of the neck and body and the limbs white. On the forehead is a large heart-shaped spot pointing downward.” To this figure Gmelin, (1. c.) gave the name of bicolor. It has been suggested by Shaw and others that perhaps this creature is the same as Lemur albifrons Geoffroy, but excepting the white on the forehead it bears no resemblance whatever to Geoffroy’s species, and the restricted area of white on the head is very unlike the almost entirely white head of L. albifrons. Miller’s animal is apparently adult, and does not seem to be in a state where the color of the pelage is changing to something else, and this condition, moreover, is not habitual with the Lemurs, as the young usually closely resemble the adults. L. albifrons is not common in collections, and it cannot be said that it is at all well known in so far as its appearance at all ages is concerned, but with the knowledge that we have at present, it would be very unwise to reduce Geoffroy’s name to a synonym in favor of that bestowed by Gmelin to an animal he probably had never seen, and which has no representative in any collection. Miller’s example 156 LEMUR should more properly be assigned a place among those quasi species deemed indeterminable. Lemur cinereiceps Milne-Edwards and Grandidier.

Top of head, face and ears gray; rest of pelage, body, limbs, hands, feet, and tail bright rufous red. The type of this form was not in the Paris Museum although a diligent search was made for it, and I could not therefore give a description from the example, nor take any measurements. No description was ever published so far as I have been able to learn, except the short one in Forbes, (1. c.) and all we know of the form, is the figure in the work above cited. Whether or not a figure alone is sufficient (no matter how well colored it may be) to establish a species, naturalists are not yet in accord, and as the above brief description was taken from the plate, it may not be sufficient to make amends for former lapses. The plate exhibits a figure of an apparently distinct animal. Lemur macaco Linnaeus. Lemur macaco Linn., Syst. Nat., I, 1766, p. 44; Erxl., Syst. Reg. Anim., 1777, p. 67 ; Gmel., Syst.

The type of this form was purchased by the Paris Museum from the Zoological Society of London, the skull, however, is in the British Museum. It is a large animal, and may possibly be a melanism of L. rufus or L. fulvus, or a male of some species of the L. macaco style. The fact that nothing is known of its habitat, or whence the specimen came, makes it difficult to form an opinion upon its specific value, and we are therefore compelled, for the present, to keep it separate from the other species of the genus.

South, and southwestern borders of Betsileo Prov¬ ince, Central Madagascar. Province Anossi, (Schlegel and Pollen). Genl. Char. Prominent spur in old males on forearm above wrist ; comb-like growth, in females and young, continuous with palm of hand by a hairless skin ; near this is a gland surrounded by stiff hairs ; tail long, conspicuously banded. Color. Top of head grizzled white and black; neck, shoulders and back to rump and sides of body fawn, hairs tipped with white ; a black band from cheeks to shoulders; outer side of limbs and rump pearl gray ; inner side of limbs, and under part of body white ; hands gray like arms ; feet white ; ears white ; tail banded with numerous rings alternately black and white, tip black. Measurements. Skull : occipito-nasal length, 75 ; Hensel, 70 ; zygo¬ matic width, 45.5; intertemporal width, 15; width of braincase, 39; palatal length, 35; median length of nasals, 21 ; length of upper molar series, 27 ; length of mandible, 53 ; length of lower molar series, 30. This is the most beautiful of all the Lemurs, the soft, delicate color¬ ing of the body, with the strongly contrasted rings on the long tail, easily enabling the species to exceed all others in the attractiveness of its appearance. Of course it would be a conspicuous object anywhere, and when met with in the localities it frequents, the traveller’s attention would be at once arrested, and the following statement of its habits was given by one of its fortunate observers, Mr. George A. Shaw in the Proceedings of the London Zoological Society (1. c.). He says that in his seven years’ experience of the species the animals were found only in the south and south western part of Betsileo Province. This province is on the center table land from 100 to 250 miles south of Antananarivo, the capital, and extends for 150 miles with a width of 50 to 60 miles. The eastern side is covered with forest, fringing the table land, and covering the slopes into the lowland bordering the sea. The Lemurs 160 LEMUR i dwell among the rocks in the south and southwest portion, and are not arboreal. Their hands (hands and feet?) have long, smooth, level and leather like palms which give them a firm footing on the wet, slippery rocks, over which they easily travel, as a fly does on a pane of glass, and people, although barefooted, are unable to follow them. The thumbs are smaller in proportion to those of the forest Lemurs, whose fingers are suitable for grasping as they spring from tree to tree, rarely descending to the ground except for water. There are very few trees where the Ring-tailed Lemurs live, and these are stunted and bushy. These Lemurs have two long upper fangs, longest in the males, and with these they take away the outer coating of the prickly pear which is full of fine spines, and which forms their principal food, as it grows abundantly in the crevices and around the foot of the rocks. In sum¬ mer they feed on various kinds of wild figs and bananas. The fangs, (canines), are doubtless used for self defence, although when fighting they depend chiefly on their hands, with which they scratch and strike, and a male has been seen to whip a dog larger than itself by these means. They are very easily tamed, and will eat almost any kind of fruit, but no cooked meat ; cooked rice however, they can be induced to eat. They do not drink in the wild state, as is proved by native state¬ ments, and from the fact of their abstaining for a month or more when in captivity, and living on bananas during that period. The Lemurs living on the west, including two species of white Lemurs, (Propithe- cus), subsist without water, but those on the east invariably drink when feeding. There is no difference in appearance between the sexes. Lemur yareegatus Kerr. Lemur macaco variegatus Kerr, Anim. Kingd., 1792, p. 86, No. 98. Lemur macaco (nec Linn.), 'Schreb., Saugth., 1775, pi.

Madagascar. Geogr. Distr. North eastern Madagascar from Adenpone to Cape Masoala at the entrance of Antongil Bay, and into the interior to Bengoa. Genl. Char. Color black and white, and variable in the extreme in the arrangement; apparently purely individual. Tail thick, long; ears hidden in fur ; chin naked ; coat thick and woolly. Color. Excessively variable. Possibly the most usual style has the nose black on top, the sides covered with short yellowish white hairs; cheeks, forehead, top of head, neck, upper back, arms to elbows, wrists, outer edge of thighs, ankles, inner side of limbs, under parts, hands, feet and tail black ; rump, flanks, outer side of thighs, and legs to ankles white. In some examples there is a white collar around the neck beneath the head, and the hind neck is white down to the lower back, and this is often tinged with orange or deep buff ; but the extent and distribution of these two colors varies so greatly that it is practically impossible to find two individuals alike. Measurements. Skull: occipito-nasal length, 99; Hensel, 89; zygomatic width, 59; intertemporal width, 40; palatal length, 44; medium length of nasals, 31 ; length of upper molar series, 30; length of mandible, 39; length of lower molar series, 35. Coquerel states, (1. c.) that this animal is considered sacred by the natives of Tamatave, and they say it worships the sun, and prays to it every morning. This idea doubtless comes from a habit this Lemur has in common with the Mococo. An individual of this species which he had in captivity, at the first rays of the sun appearing sat up on its hind legs and remaining erect, would open and extend the arms holding them in this position while looking at the sun, as if its vivifying in¬ fluence would by this action be received within itself. One, seeing Lemurs in European menageries, would obtain no idea of the activity they display in their native wilds, or of the grace of their movements and their incredible agility in the Madagascar forests, as they launch 162 LEMUR themselves from branch to branch with astonishing precision, and pass from tree to tree in prodigious leaps.

Eastern Madagascar, from Bay of Antongil in the north to Masindrano in the south. Color. Back of neck and circle around ankles white; ruff, rusty or orange red; upper part and sides of body, and outer side of limbs rusty red; under parts, and inner side of limbs and tail, black. Varia¬ tions from this style are frequently seen, but the predominant color is usually some shade of red. Measurements. Size same as L. variegatus.

This handsome variety of Lemur variegatus apparently ranges to the south of that species on the eastern coast of Madagascar, the two forms meeting at the Bay of Antongil. While exhibiting sundry styles of different colorations, it is not subject to such extreme variations as those shown by its relatives. Its bright color gives it a very gay and attractive appearance, even more striking than that of the strongly contrasted hues of L. variegatus. No especial records have been given of the habits of this form, but it is not supposed that they differ in any degree from those of its relative. VOLUME I. PLATE XIX LlCHANOTUS LANIGER.

This curious little animal, with a coat much resembling wool, is strictly nocturnal in its habits, sleeping during the day. It is arboreal, and inhabits the forests on the eastern coast of Madagascar, and along the Bay of Passandava on the west coast. Examples from the north western part are smaller and of a lighter color. Coquerel (1. c.) states that this animal is found in the great forest of Tsasifout on the Island of St. Mary and is known to the natives by the name Ampongui. It is more decidedly nocturnal than the true Lemurs and a more stupid animal. 166 PROFIT HECU S GENUS PROPITHECUS. SIFAKAS. I. 2—2 l—l 5 1—1 1— 1 » 2—2 2— 2 > M. U = PROPITHECUS Bennett, Proc. Zool.

Skull : upper in¬ cisors protruding, the inner pair approximating and longer than outer ; braincase high ; diastema between upper canines and premolars ; lower molars quadricuspidate. The Sifakas, as these rather handsome animals are called, are remarkable for their wonderful diversity of coloration. As now restricted only two species are recognized, each having several subspecies, which are only met with in certain localities apart from their species. The color is usually white varied with yellowish, red, or black markings. Sometimes black phases occur when the entire pelage is of that hue. The animals are only found in Madagascar, and very little has been recorded of their habits. They are dwellers of many parts of the Island, and are not confined to the forests, but are met with in the arid tracts, and on the plains where trees are infrequent. Albino individuals are found, mostly belonging to the P. v. deckeni variety, a form that exhibits very great diversity of color and pattern among individuals. In fact examples of most of the forms vary so much in this respect that many descriptions would be necessary to make them recognizable, and enable one, not familiar with the group, to attribute the examples to their proper place among the different accepted forms. v The Sifakas are venerated and never killed by the natives of Mada¬ gascar. They are inoffensive animals, going about in troops of half a dozen individuals, and live upon various leaves, fruits and flowers, quite a different diet from that of other species of Lemurs. During the heat of the day they sleep in some secluded place among the foliage and are active in the early mornings and evenings. VOLUME I PLATE XX Propithecus DIADEMA. No. 31253 Amer. Mus. Nat.

On the west coast, in the northern part P. v. coronatus is met with from the Bay of Mozamba to the Manjaray River, and also for some distance into the interior. Between the southern base of the eastern range of mountains and the River Tsidsibon P. verreauxi is found; while P. v. coquereli is met with from the north side of Bombetok Bay to the south side of Marendry Bay, the Betsiboka River being its southern limit. In the center of the west coast on the great plains between the Rivers Mananbolo and Man- zarayo, P. v. deckeni has its range. KEY TO THE SPECIES AND SUBSPECIES. A. Face and nose black. a.

Eastern coast of Madagascar, in forests on the eastern side of the high mountains between the Bay of Antongil on the north and the River Masara on the south. Genl. Char. Those of the genus. Color. The single species of this genus is so extremely variable that any description given can only be regarded as pertaining to the specimen then under consideration. No two individuals are exactly alike and the varieties of the color patterns are only limited by the number of examples in a collection. Face black or dark gray; head, INDRIS 177 neck, back, shoulders and arms black ; in some the crown is white ; sides of neck and forearms are grayish white; a band starting from point in middle of back and widening as it goes down and embracing the entire rump and root of tail, white ; sides dark gray tinged with brown ; upper surface of thighs from body to middle of leg below knee inside, black; rest of thighs and legs dark gray; under parts of body and tail gray ; hands and feet black. In some specimens the lower back is ashy gray ; flanks bright rufous ; tufts over ears large, upright, black. Although exhibiting such a great variety of color patterns as well as diversity of hues, the species can never be confounded with any other, its large size and stumpy tail making it at all times easily recognizable. Measurements. Skull: occipito-nasal length, 91; Hensel, 82; zygomatic breadth, 58; intertemporal width, 36; length of nasals, 20; width of braincase, 43 ; length of upper molar series, 31 ; palatal length, 35 ; length of mandible, 66 ; length of lower molar series, 34. Coquerel (l.c.) has given an interesting account of the habits of this species as observed by him in Madagascar. He says it is well known to the inhabitants who call it Babakotou, but never Indri which means in their language “Behold,” “look,” “see there!” It is probable when Europeans first hunted this animal, the natives drew their atten¬ tion to it by calling out Indri, and in this way the idea was formed that that was the native name for it. It is very common in the forests of Tamatava where it is considered sacred. The natives never kill it, and they say that the trees on which the Babakotou live supply a sure remedy for many forms of illness ; and they gather carefully the leaves of the trees in which they have seen the animals, for their benefit. The natives state it is very dangerous to attack a Babakotou even with a spear. If this weapon is thrown at one, you may be sure it will be seized in its flight before reaching its mark and will be immediately hurled back at the thrower, and the Babakotou never misses its aim. The tales of which the Indri is the hero are endless. Its ways are full of mystery, and it is subject at birth to a severe trial. When the young one is born, the female takes it in her arms and throws it to the male, who is stationed at a considerable distance away, and he throws it back to its mother, and this is repeated a dozen times or more. If the baby falls to the ground, it is left there, the parents making no effort to recover it, but if it passes the trial without falling, it is tenderly cared for. The Indri is not found on any 178 INDRIS of the outlying islands near Madagascar. This animal is gregarious and goes in troops of considerable numbers, is the largest of the Lemu- roides, and is not nocturnal. One of its names is Amboanala or ‘Dog of the Forest/ so called on account of the howls it utters, and which resemble those of a dog. Its voice is very powerful, the laryngeal sac contributing to this, and enabling the creature to utter loud cries. It lives in the trees and subsists mainly on fruits of various kinds, but will eat the brains of any bird it can catch. Its melancholy cry is frequently heard in the forest resembling that uttered by a person in distress. According to Dr. Vinson the natives free these animals if they find one in captivity and bury them when dead. The Betanemena tribe relate a legend of a certain tribe which was at war with neighbors and fled for refuge into the forest. Its enemy pursuing and guided as supposed by human voices, saw before them a troup of Indri, and believing those they were following had been changed into beasts, they fled terror stricken, while the fugitives vowed eternal gratitude to their deliverers, and have never since harmed them.

Tamarin Gray, Cat. Monkeys, Lemurs and Fruit-eating Bats, Brit. Mus., 1870, p. 68. Face naked, hairy in young; no mane; head in front of ears bald; ears naked, exposed; tail not ringed. With this genus we enter the Suborder Anthropoidea. The Tamarins all belong to the Platyrrhine or New World Monkeys, and in many respects occupy the lowest rank. They possess but thirty- two teeth, instead of thirty-six as in the Cebhxe and higher Apes, as well as in man, the discrepancy being caused by the absence of two molars in each jaw, only eight in all remaining. The Tamarins placed in this work in the four genera Seniocebus, *Cercopithecus, Leontocebus with a subgenus Marikina, and CEdipomidas, are small delicate creatures with silky fur, and long, thick, almost bushy tails. By the earlier writers they were contained either in Callithrix or Hapale with the Marmosets, but are now not considered cogeneric with the species contained in the first of those genera, and the second Hapale, being antedated, becomes a synonym. The chief difference between the members of Callithrix and the species now under consideration is found in the teeth, the canines of the lower jaw being longer than the incisors, a distinction deemed by some Authors as perhaps hardly sufficient to cause the Tamarins to be separated generically from their relatives. Tamarins and Marmosets resemble each other, and the skulls with the large braincase are much alike. Both groups possess but little intelligence, as the cerebrum, in its smooth surface almost lacking in convolutions, would seem clearly $ *See Elliot, in Bull. Am. Mus. Nat. Hist., N. Y., 1911, p. 341. 180 SENIOCEBUS to indicate. These animals possess somewhat rounded heads, and large eyes and mouths ; the ears are conspicuous, standing out from the hair, and the face is small and short. Rather long whiskers and manes are often present. In captivity, even in their own land, they rarely live long, and usually succumb in a brief period when carried to northern climes, cold temperatures being fatal to them. They are pretty creatures, and a number of the species bear a certain resemblance to each other, and so it is possible to arrange them in groups, dis¬ tinguished by the hair on head and neck, being respectively long or short. LITERATURE OF THE SPECIES OF THE FOUR GENERA OF TAMARINS AND MARMOSETS. 1758. Linnesus, Systema Nature. Two species are described as Simia cedipus = CEdipomidas (edipus ; and Simia midas = Cercopithecus midas. 1766. Linnceus, Systema Natures. The two species of the earlier edition of this work are also given in this one, and another added, Simia rosalia — Leonto- CEBUS ROSALIA. 1777 . Erxleben, Systema Regni Animalis. Under the genus Callithrix, in which the earlier writers were accustomed to place the Tamarins, three species only are given : (C.) cedipus; (C.) rosalia; and (C.) midas. 1788. Gmelin, Systema Natures. The three Linnaean species already mentioned are here recorded, and no new ones added. 1806. Fischer, in Bulletin de la Societe Imperiale de Moscou. Cercopithecus midas redescribed as Simia lacepkdii. 1811, Humboldt et Bonpland, Recueil d’ Observations de Zoologie (1815).ef d’Anatomie Comparee. Leontocebus leonina described as Simia leonina. 1812. E. Geoffroy Saint-Hilaire, in Annales du Museum d’Histoire Naturelle, Paris. Six species are enumerated under the genus Midas, the valid ones being, ( M .) ursulus = Cercopithecus ursulus; (M.) labiatus = Leontocebus labiatus; ( M .) rosalia = Leontoce¬ bus rosalia; (M.) osdipus — CEdipomidas cedipus; and ( M .) ruhmanus = Cercopithecus rufimanus. The remaining (M.) leoninus is a most doubtful species, no examples ever having SENIOCEBUS 181 been secured. The first two of the valid species are described for the first time. 1820. Kuhl, Beitrdge zur Zoologie und vergleichenden Anatomie. Seven species are here given, one of which is described for the first time as {Midas) chrysomelas. The other valid species are (M.) ursulus = Cercopithecus ursulus; (M.) labiatus; (M.) rosalia; both now included in the genus Leontocebus ; and (M.) cedipus, now placed in the genus CEdipomidas. The last valid species (M.) rutimanus = Cercopithecus rufi- manus; and (M.) leoninus a doubtful species, no example extant. 1820. Desmarest, Mammalogie ou Description des Especes de Mam- miferes. The list given by Kuhl is repeated in this work, all the species placed in the genus Jacchus. 1823. Spix, Simiarum et Vespertilionum Brasiliensium. Five species are enumerated in this work, four of which are described for the first time under the genus Midas. They are {M.) fuscicollis; {M.) nigricollis; (M.) mystax; and (M.) bicolor. These are now all placed in the genus Leon¬ tocebus, except bicolor, which is a species of Seniocebus. The fifth species is (M.) cedipus = CEdipomidas cedipus. 1826. Maximilian, Prinz von Wied-Neuwied, Beitrdge zur Natur- geschichte von Brasilien. Under the genus Hapale five species are enumerated only two of which belong to Leontocebus ; viz. : L. rosalia and L. chry¬ somelas; the latter more fully described than in the previous work above cited. The other species are ( H .) jacchus; ( H .) leucocephalus ; and ( H .) penicillatus ; all belonging to the genus Callithrix. 1829. Fischer, (/. B .) Synopsis Mammalium. In the second section of the genus Jacchus ten species are enumerated of whichSeven are valid, viz.: (/.) midas; (/.) ursulus; (/.) labiatus; (/.) chrysomelas; (/.) rosalia; (/.) chrysopygus; and (/.) argentatus. The first two are now included in the genus Cercopithecus, the rest in Leon¬ tocebus; and (/.) cedipus = CEdipomidas cedipus. The other is (/.) leoninus doubtful. No new species described. 1840. R. P. Lesson, Species des Mammifbes Bimanes et Quadru- manes. The genus Cercopithecus is here represented by Midas, with 182 SENIOCEBUS one species (M.) tamarin = Cercopithecus midas; the C. ursulus being regarded as the male of middle age, and Leon- tocebus fuscicollis being the young. The Genus CEdipus has CEdipus titi = (Edipomidas cedipus; Cercopithecus bicolor (Spix), being the immature animal. Under the genus Leon- to pith ecus = Leontocebus, of the subgenus Marikina, the following species and varieties are given: L. aurora = L. rosalia ; L. fuscus = L. leonina ; L. ater = L. chrysopygus ; var. A. and var. B. L. chrysomelas. The method of arrange¬ ment adopted by this Author is unsatisfactory and somewhat confusing. 1840.

A similar arrangement with that of previous Authors is here given, and species belonging to different genera are brought together in the genus Hapale.

The species are (M.) rosalia; ( M .) chrysomelas; (M.) labiatus; (M.) pileatus; (M.) mystax ; (M.) devillii ; (M.) rufoniger = L. nigricollis (Spix) ; (M.) nigrifrons; SENIOCEBUS 183 M. havifrons — L. fuscicollis (Spix) ; (M.) illigeri; and (M.) weddeli. All these are now included in the genus Leontocebus. ( M .) cedipus, and (M.) geoffroyi, are now placed in the genus CEdipomidas; while (M.) ursulus and (M.) rufimanus are arranged in the genus Cercopithecus ; and ( M .) bicolor in the genus Seniocebus. 1852. I. Geoffroy Saint-Hilaire, in Archives du Museum d’Histoire Naturelle, Paris. In this paper five Tamarins are given, being those described in the Comptes Rendus in 1848 and 1850. They are (Midas) pileatus; ( Hapale ) devillii ; ( Hapale ) nigrifrons; (Midas) havifrons = Leontocebus fuscicollis; and (Midas) rufoniger = L. nigricollis. Midas and Hapale were used at different times for the generic name, but in this paper Midas is selected as the name of the genus. 1855.

The additional species are Leontocebus ruhventer = L. labi- atus ; L. fuscicollis ; L. nigricollis ; L. weddeli ; L. illigeri ; and CEdipomidas geoffroyi. All are placed in the genus Hapale with three subgenera, Jacchus, Liocephalus, and Leon¬ tocebus. The species now arranged in the genus Callithrix are also included in Hapale, and in the first two subgenera, but Leontocebus has merely the species of Marmosets belonging to it, and to CEdipomidas. No new species described. 1862. Reichenbach, der Vollstdndigste Naturgeschichte der Affen. The species of Leontocebus are placed in this work in the genera Leontopithecus, Marikina, Midas . and Seniocebus as follows: (L.) leoninus; (M.) rosalia; (M.) chrysomelas; (M.) albifrons; (M.) rufimanus; (M.) ursulus; (M.) ruhventer = L. labiatus; (M.) fuscicollis; (M.) bicolor; (S.) chrysopygus; (S.) mystax; (N.) nigricollis; (S.) pileatus; (S.) rufoniger = L. nigricollis; (5\) devillii; (S.) nigrifrons; (S.) havifrons = L. fuscicollis; (S.) illi¬ geri; (S.) weddeli; (S.) erythrogaster = L. labiatus. 1864.

GEOGRAPHICAL DISTRIBUTION OF THE SPECIES. The most northern country inhabited by the Tamarin Monkeys is Central America where in the southern portion, in Costa Rica and extending its range through Panama to the Isthmus, CEdipomidas geoffroyi is found. In the Guianas, northern South America, Cer- copithecus midas is a dweller of the English and Dutch Guianas, and Cercopithecus rufimanus is met with in French Guiana, and on the banks of the Rio Araguay, Province of Goyas, Brazil, and as stated by Tschudi, also in Peru. The great territory of Brazil contains, as would be supposed, the greatest number of species, twenty-four in all including C. rufimanus just mentioned. In the vicinity of Para on the lower Amazon, near the mouth of the Rio Tocantins, C. ursulus is met with, and in the forests through which the Ilheos and Pardo flow in eastern Brazil, Leontocebus chrysomelas occurs; and strangely enough, though it is not known from Western Brazil, yet, according to Tschudi, it is a native of Peru; and on the Rio Negro and on the Upper Amazon west of Barra, Seniocebus bicolor is found; and on the north shore of the Amazon at Faro, near the mouth of the River Yamunda Seniocebus martinsi was taken. In south eastern Brazil in the Province of Rio Janeiro, L. rosalia is found, and if the animal mentioned by Bates (1. c.) under the name of Midas leoninus is the same, then it extends its range to the Upper Amazon, although there are no records of its appearance in the intervening districts. In the Province of Sao Paulo near Ipanema, L. chrysopygus is met with, and on the banks of the Rio Solimoens, and as stated by Castelnau and Deville, also at Pebas, Peru, L. nigricollis occurs. In the forests between the rivers Solimoens and Iga, L. mystax and L. fuscicollis dwell ; and on the banks of the Rio Purus, Upper Amazon, L. im- perator has been procured. Near the Rio Javari on the borders of Brazil and Peru, L. nigrifrons occurs, and its range extends to the Rio Copataza in Ecuador. Between the Rio Solimoens and Rio Javari, L. labiatus has been obtained, and Tschudi states it is also a native of Peru. At Tunambins on the Upper Amazon L. thomasi was obtained, its range unknown, and still more indefinite, somewhere on the Upper Amazon, no locality given, L. lagonotus was taken. At Popayan, Colombia, the monkey seen by Humboldt and called by him 186 SEN 10 CEB US Simia leonina, but not procured, occurs. In Colombia, at Cartagena and Turbaco CEdipomidas cedipus is found, and on the River San Jorge Seniocebus meticulosus was taken, and in Ecuador on the Rio Napo L. tripartitus and L. graellsi have been obtained ; and in the same State on the banks of the Rio Copataza, L. apiculatus and L. illigeri are met with, the latter species possibly extending its range into Colombia, (see I. Geoff., Cat Primates, p. 65). In Peru near Pebas, L. pileatus was procured; and on the banks of the rivers Ucayali and Huallaga, L. devillii dwells. Finally, in the Province of Apolobamba, Bolivia, L. weddeli is found. In the above recapitulation of the general distribution of these small monkeys, the ranges are given according to the records obtained from specimens collected. While some species may have a restricted habitat, others probably have much more extensive ranges than those known at present. The interior of Brazil, removed from the banks of its great rivers, is as yet im¬ perfectly known, and it will not be until its vast forests and inland savannas have been thoroughly penetrated and explored, that the Geographical distribution of its Faunae, and the ranges of its individual species can be definitely ascertained.

This monkey has a peculiar appearance with its bare head and white coloring, which makes it rather exceptional among the Tamarins. There is also a total absence of brilliant colors possessed by many of its relatives, save on the under parts, inner side of legs and tail beneath. The immature individuals have the head covered with short white hairs. The type in the Munich Museum is not adult, the head being covered with short white hairs. It is in good condition and is well represented in Spix’s plate, though the coloring in the specimen is not so bright. Another specimen, not obtained by Spix, is older with the head entirely bare. Bates, (1. c.) states that this monkey was rather common in the forests at Barra on the lower Amazon, and is restricted so far as he knew, to the eastern bank of the Rio Negro. A specimen in the Paris Museum, was obtained by Castelnau and Deville at Pebas on the Upper Amazon west of Barras, where Bates and Natterer also found this species. Like its relatives it goes in small troops, running along the main boughs of the loftier trees, and climbing perpendicular trunks, but never taking flying leaps. 188 SENIOCEBUS Seniocebus meticulosus Elliot.

Resembles the male, except there is very little of the bright bay color on the shoulders and rump, while the thighs are colored like the upper parts, dark drab, the hairs tipped with bay. Tail like that of the male. Two examples of this handsome little monkey, the third species known of the genus, were received at the American Museum of Natural History in New York from Mrs. E. L. Kerr, Cartagena, collected in the forest on the River San Jorge, Colombia. While bearing in some of its coloration a resemblance to the species known for so long a time from Brazil, S. bicolor, its bright bay rump and thighs, pure silvery white under parts and inner side of limbs, and grayish white hands and feet cause it to differ in a conspicuous manner from its relative. The lately described S. martinsi (Thomas), is the third known species of the genus. SENIOCEBUS 189 Seniocebus mabtinsi (Thomas). Leontocebus martinsi Thos., Ann. Mag. Nat.

Against this view stands the almost unanimous opinion of the Commission on Zoological Nomenclature appointed by the International Zoological Congress held at Leyden in 1810. The report which was adopted by a vote of eleven in favor to one against is as follows: “It is clear that Gronow’s nomenclature is binary, that is, he names two units or things, genera and species. His generic names, therefore, cor¬ respond to the provisions of the Code, and are to be accepted as available under the Code.” It is not to be doubted, therefore, that an Opinion passed with so much unanimity will become a Law at the next meeting of the Congress, and Gronow’s name will be accepted by all Naturalists. fFor Geographical Distribution, see Seniocebus, p. 185.

It was less afraid of the neighborhood of man than any other of its Tribe. He at times saw it in the woods bordering the suburban streets, and once saw two in a thicket behind the house of the English Consul at Nazareth. Its mode of travelling along the boughs of the lofty trees resembled a Squirrel, and it does not go on the slender branches, nor make flying leaps, but confines itself to the larger boughs and to the trunks of the trees, its long nails enabling it to cling securely to the bark, and it often rapidly encircles the trunks of the perpendicular trees. It is quick, restless and timid, and has much curiosity, for should a person pass under the trees on which a flock of these little creatures is running, they always stop to stare at the intruder. In Para, it is often seen tamed in the houses, but when first captured, or tied up, it is very timid and irritable, not allowing itself to be approached, but retreating when any one draws near. When treated kindly, however, as it generally is in the houses of the natives, it becomes very tame and familiar. He once saw one as playful as a kitten running after the negro children and fondled by them. It did not like strangers to sit in the hammock which was hung in the room, and tried to bite them. It fed on bananas and insects, especially spiders and grasshoppers. This little monkey has a very intelligent and pleasant face, and when its curiosity is excited, it in¬ clines its head to one side and has a very knowing expression. Although the absence of convolutions in the brain would seem to indicate a low type, Bates considered this a very unsafe guide, for in mobility of expression and general ways, he considered these small monkeys resem¬ bled the higher Apes, more than any other Rodent animal with which he was acquainted. 194 LEONTOCEB US GENUS LEONTOCEBUS.

While it has undoubtedly faded somewhat in the more brilliant and delicate colors, its general aspect cannot have changed much, and what is now dark brown was never black as given by most authors as the color of the body ; for the head, hands, feet and tail are as black as they probably ever were ; the tail alone showing a purplish tint which no doubt always existed. The brilliant orange red of the under parts still remains where the hairs have not disappeared. Measurements. Total length, 520; tail, 390, (skin).

The type of Midas rufiventer Gray, is like L. labiatus but has a small gray spot on the crown between the ears and the nape. This is probably an individual peculiarity, and is the only difference in color leontocebus 197 between the example and specimens of L. labiatus, and is hardly sufficient to be regarded as a distinctive character. Gray in his descrip¬ tion (1. c.) states that this head spot was the same color as the under parts, chestnut brown.” At present it is gray, as above stated, and must have faded considerably. The under parts are now ochraceous rufous, and this part, in the intervening sixty or more years, has un¬ doubtedly faded from the more brilliant color of the living animal. It would seem most probable that this example is not distinct from L. labiatus. Slack’s type of (M.) elegantulus is in the National Mu¬ seum, Washington, in excellent preservation. The arms to elbows, and legs to ankles, and upper parts of body are mottled black and buff, not dark reddish brown or blackish as in the type of L. labiatus, but this difference may be caused by age. The rest of the pelage is like that of the type of L. labiatus. Midas griseoventris Goeldi, I have not seen, as there was no example in any European Museum. Its chief character for separating it from the present species appears to be the color of the patch or stripe on the crown which is stated to be white. This certainly is not the color of the patch or stripe on the crown of L. labiatus type. Gray’s rudventer has now a gray patch on the crown although, as stated above, it was described as chestnut brown. It may be there is a race of L. labiatus with a gray or white crown patch, but in such a case it would have to be determined whether Goeldi and Gray’s examples represent the same species, and if they do, Gray’s name rudventer though a poor one, would take precedence, and comparisons of specimens would be necessary to decide this. For the present, therefore, I place Goeldi’s name among the synonyms of L. labiatus with a question mark. Leontocebus pileatus (I. Geoffroy). Midas pileatus I. Geoff, et Deville, Compt.

The type is possibly a little darker than specimens of this species generally are, but the pale color, such as chestnut buff seen in fresh specimens, has faded to white on the back, between the shoulders and on flanks. Otherwise it still represents the species. Leontocebus thomasi (Goeldi). Midas thomasi Goeldi, Proc. Zool. Soc. Lond., 1907, I, p. 89. Type locality. Tunantins, Upper Amazon. Type in British Museum.

This species in certain ways resembles L. nigricollis Spix, but does not have the head entirely black like that species, the black being confined to the forehead. There are other differences in the coloration of portions of the body, which influence me to keep the two forms apart, although it is not impossible that eventually they may be proved to be the same species. The type has no locality, but Schlegel states that the specimen in the Leyden Museum was obtained on the Rio Javari, and Thomas received six examples from the Rio Copataza in Ecuador.

Ex specimen in British Museum. The type of Midas rufoniger I. Geoffroy, in the Paris Museum, agrees perfectly with the above description, except the upper part of the throat is a yellowish brown. This appears to be caused by the paucity of hair on that part, there not being enough black tips, which produce the color for this part, to be spread all over. Wherever the hairs are sufficiently numerous the color is black. Geoffroy’s species is without doubt the same as L. nigricollis (Spix). There are two examples of this species in the Munich Museum both marked ‘types.’ These are in good condition, only slightly discolored by dust, but the dark colors of the pelage have not faded. The skulls of each are in the specimens. Bates (1. c.) has given a very interesting account of this monkey under the name of Midas rufoniger I. Geoff. Its habits are the same as those of C. ursulus and he imagined it was a form or race of the same stock, modified to suit the altered local conditions under which it lived. One day, he says, while walking along a forest pathway, he saw one of these small creatures which was passing with a number of his fellows, miss his hold and fall head first about fifty feet to the ground. He managed to alight on his hands and feet, however, in the path, and turning quickly around he stared at the intruder on his domain for a few moments, and then bounded away to climb another tree.

This species has been united to L. devillii by some Authors, but it presents too many differences from that form to justify us, with only LEONTOCEB US 203 our present knowledge of the changes that may occur towards the adult state, in uniting them. The examples are both quite small, and judging from the teeth that show in the open mouth, the type is the younger animal, but the white face, only displayed in the front part of the whiskers of L. devillii, and the general reddish brown color of the pelage, with the absence of mottling on the lower back, cause the two types to appear so different that it would seem best to permit them to remain under different names until we have more knowledge as to the respective changes, if any, which may occur in the coloration of the pelage of L. devillii from the youthful to the adult state.

The type of Midas leucogenys Gray, is in the British Museum Collection. It is a young animal about half grown, and in all its mark¬ ings exactly corresponds with the adult ( M .) devillii Geoff roy. There seems to be no reason whatever to separate it from the present species. The type of L. devillii in the Paris Museum, presents the coloration described, but it has lost much fur from the under parts of the body, and the reddish chestnut of that part is not so pronounced as is shown in recent specimens. Bartlett, who met with this species in eastern Peru, says (1. c.) it was plentiful on the Peruvian Amazons, and he obtained examples on both the Huallaga and Ucayali rivers. There is but little difference between the sexes, the male being rather larger and darker in color, especially the long hair on nape and neck. It is an extremely delicate animal and will not bear the least cold, and he could only keep them alive for two or three weeks, as they seemed to suffer from cold, and died. The Indian women make pets of them, and allow them to stay amid the long hair on their heads, and thus protected they will live for a long time. Becoming tame they come out and feed, and having captured a spider or two, they scamper back to their refuge amid the luxuriant hair of their owners, who are usually unwilling to part with them.

Ex type Paris Museum. This strikingly colored species, so unlike any of the genus; is recognizable at once. The jet black head and throat, contrasted with the bright colors of the body make it most conspicuous. The type in the Paris Museum has retained its color so far remarkably well, and it is to be regretted that it should be permitted to remain exposed to the sunlight which will eventually destroy most of the coloring, which now eminently distinguishes it from the other species of the genus.

Ex specimen British Museum. The type in the Munich Museum has lost most of the hair on the top and sides of the head, and on arms to elbow ; the left arm is practically bare for entire length, as is also the hand. The hair is mostly gone from the under side of the body. It therefore would not serve to describe the species, and one was selected for this purpose from the British Museum Collection. The skull is in the type specimen. Leontocebus graellsi (Espada) . Midas graellsi J. de la Espada, Bol. Revista Univ. Mad., 1870, /3. 57; Milne-Edw., Archiv. Mus. Paris, I, 1878, p. 162, (note).

It is peculiarly colored and very difficult to describe. The general appear¬ ance is that of a grayish brown creature with a black head and neck, and speckled with lighter brown on the body and hind legs. The base of the tail is lighter than the body, and the fur generally is so shiny that the color is very difficult to see, and varies constantly according as the light shines upon it. Unfortunately no skull accompanied the skin. Leontocebus imperator (Goeldi). Midas imperator Goeldi, Proc. Zool. Soc. Lond., I, 1907, p. 93, fig. 23. Type locality.

Bates, (1. c.) says he once saw a tame individual of M. leoninus = L. rosalia?, which was even more playful and intelligent than (M.) Ursula. In length of body it measured only seven inches, and was friendly with every one in the house where it lived, and its greatest pleasure was to climb about the persons of those who entered. When he first visited the house, it ran to the chair on which he was sitting and climbed on to his shoulder, and looking into his face showed its teeth and chattered as though it would say, “Well, and how do you do?” It was very affectionate with its master and would climb upon his head a dozen times in an hour, and make a great show of searching for certain animalculse. Of this species Isidore Geoffroy Saint-Hilaire knew of one individual that distinguished between different objects in an engraving. When shown figures of a cat and wasp,, it was very much frightened, but when it saw a grasshopper or beetle, it precipitated itself on the picture and tried to seize them.

Total length 7 to 8 inches. No specimens of this monkey have been procured. Humboldt saw two living individuals at Popayan and from these he made his descrip¬ tion and gave the name of leonina (1. c.). It inhabits the plains of Mocoa, and the fertile banks of the Iga and Japura rivers, never goes into temperate regions, and is rare even in the country it inhabits. Whether these specimens represent a distinct species, or some state of pelage of L. rosalia, or a dark form of that species it is impossible to state, and any decision regarding it will have to be deferred until examples are procured.

Skull: braincase large; facial region short; orbits large; upper incisors longer than the canines, and all project outward. The Marmosets are small delicate creatures, possessing a soft, thick, silky fur, and a long rather bushy tail. In color there is much variety among them, and some have ringed tails. In disposition they are very timid, and while attached to, and familiar with those they are accustomed to meet daily, are shy with strangers, and apt to meet advances with sharp bites. The smooth skull, although the braincase is large, indicates a low order of intelligence. The female produces two or three young at a birth contrary to the general rule, as the females of these Anthropoidse have usually but one. VOLUME I. PLATE XXVII. CALLITHRIX LEUCOPUS. No. 98.] 0.3.1.

Geoffroy gives 1815 as the date of Humboldt’s article. 1820. Desmarest, Mammalogie ou Description des Especes de Mammi- feres. The genus Jacchus is divided into two subgenera Ouistiti and Tamarin. In the first of these is placed the species given by Erxleben enumerated above, without any additions ; while Tamarin includes such species as were known to the Author, and which are in this work contained in the genera Seniocebus, Leontocebus and QEdipomidas. 1820.

Three species of Callithrix are given in this work under the genus Jacchus, viz. : pygm^eus ; albicollis ; and penicillatus , the first two described for the first time. 1829.

Following the arrangement adopted by Desmarest, all the species enumerated by him belonging to different genera, are in this list included in the genus Hapale. 1840. R. P. Lesson, Species des Mammiferes Bimanes et Quadru- manes. The genus Hapale in this work contains the species then known, but which are now placed in the genus Callithrix. It is divided into several subgenera, and the few species recognized have many varieties. 1st subgenus is Hapale with two species ( H .) leucotis = C. jacchus; and ( H .) melanotis = C. peni- cillata Humboldt. The first has four varieties, all valid species, viz., A. C. aurita; B. (/.) vulgaris = C. jacchus; C.

C. pygm^a is placed in Cebuella; and melanura = argentata, in Mico. All of which genera are unnecessary. In the Appendix to the Catalogue, C. sericea, (= Callithrix chrysoleuca) ; and C. chrysoleuca are placed in the genus Micoella. 1876. Schlegel, Museum d’Histoire Naturelle des Pays-Bas, Simice. The species of Callithrix are here placed in the genus Hapale, as was customary with many of the earlier Authors. Simla argentata Linn., is kept distinct, because its habitat was different from that of C. melanura — C. argentata, and it could not be an albino because its eyes were black and not red ! 1876.

The majority of the species of this genus are natives of Brazil, one only extending its range into Bolivia, and one inhabiting Colombia. C. goeldi has no ascertained locality, as the unique type was brought alive to the City of Para, and it was not known whether it was captured in the vicinity or taken farther to the westward on the Amazon, or on one of its tributaries. At Santarem, at the mouth of the Rio Tapajos C. santaremensis was procured, but its range is quite unknown. C. jacchus is stated to have been obtained on the Island of Marajo, lying between the mouths of the Amazon and the Rio Para. In the vicinity of Bahia C. albicollis has been obtained, and south of the Bay Todos os Santos, C. humeralifer occurs. C. penicillata ranges from, and including the Province of Goyas, through that of Minas Gerses, and in Espirito Santo on the east coast, between 14 and 17 degrees South Latitude; and C. p. jordani is found in the south west portion of Minas Geraes. In the last named Province C. leucocephala occurs, ranging into the Province of Espirito Santo ; and in Matto Grosso C. argentata is found. This species is also met with in Bolivia, and a specimen ac¬ cording to I. Geoffroy is in the Paris Museum brought from Para by Castelnau and Deville. On the banks of the Upper Parana to the Province of Sao Paulo, C. aurita occurs, while in the last named Province at Engenhiero Reeve C. flaviceps was procured. At Booba on the Lower Rio Madeira C. chrysoleuca was obtained; and in the forests along the Rio Solimoens and Rio Ucayali, C. pygm^ea dwells, and lastly at Medellin in the Province of Antigua, C. leucopus was found.

CALL1THRIX 223 There are several specimens of this species in the British Museum, but none of them was selected by its describer as the type, a most unfortunate omission.

The type of M. sericeus Gray, in the British Museum cannot be separated from C. chrysoleuca. There was no skull of the species in the Vienna Museum of the four examples in the collection, and the measurements given above were taken from the type of M. sericeus Gray. This is a peculiar little animal, giving, at first, the impression that it must be a partial albino, but all the specimens agree in their coloring, and it is a very pretty species. 224 CALLITHRIX Callithrix goeldi Thomas. _ . _ Callithrix goeldi Thos., Ann.

Hair on back and shoulders long, silky, projecting beyond ears. Color. Head, limbs and upper parts blackish brown, the hairs at base are broccoli brown graduating into black, and tipped with pale brown ; white tufts exist on head in front of ears, and on either side of the back at the loins, and there are white hairs scattered about the forehead ; feet, hands, under parts and tail black, with light tips show¬ ing on some of the hairs in the tail. Ex type British Museum. No skull to the specimen. The specimen is in poor condition and misshapen, so that it would be impossible to give correct measurements. The skin of the hands and feet has been filled with some material and is stretched, making these members appear unusually broad, and the skin of the body has been shortened in making up. There is no species of the genus known to me to which this specimen can be assigned, but as the animal had been in captivity, and possibly, as suggested by Mr. Thomas, had been injured, this accounts for the white hairs on different parts of the head and body. We must wait for additional examples to enable us to decide what shall be its proper place in the genus. Callithrix santaremensis (Matschie). Hapale santaremensis Matschie, Sitzungsb. Ges. Naturf.

Ex type in British Museum. This subspecies is not so gray as C. penicillata, but darker and browner; the band above the slate colored base of the hairs is tawny and not ochraceous, and this causes the general darker hue of the animal ; the under parts are much lighter, and more yellowish brown on sides of abdomen and inner side of thighs. 228 C A LLITHRIX Caulithrix jacchus (Linnaeus).

C ALLITHRIX 229 Bates, (1. c.) states that while walking about the streets of Para he counted thirteen different species of monkeys, and, of these, two he never met again in any part of the country. One of these was Hapale jacchus. “It was seated on the shoulder of a young mulatto girl, as she was walking along the street, and I was told had been captured in the island of Marajo.” This appears to be about the only identified locality in which this species is found, for previous authors, as a rule, in giving the range of C. jacchus have so confounded several species together, as to make it practically impossible to designate the geo¬ graphical limits of this long and well known species ; and of its range in Brazil but little is known even at this late day.

Ex type Paris Museum. Measurements. Size about as C. jacchus. Skull in mounted type specimen. It is most likely the fact that the bare head and throat of the type is caused by the hairs having slipped, as scattered ones still are to be seen, rather than that these naked parts are natural. The scattered colored places on the head, and the whiteness of the hairs on the upper part of the body, and the white mottling of the back and rump would seem to be more a condition of partial albinism of C. jacchus than characters indicating a distinct species. However, it is impossible to establish this as a fact, and until more proofs are obtained in other specimens, duplicating the type, or examples of C. jacchus in various albinistic stages, the present specimen will have to remain under the name given to it by Geoffroy. Bates (1. c.) gives the following account of this species as observed by him at Santarem : “I saw in the woods on one occasion, a small flock of monkeys, and once had an opportunity of watching the move¬ ments of a sloth. The monkeys belonged to a very pretty and rare species, a kind of Marmoset, I think the Hapale humeralifer de¬ scribed by Geoffroy St. Hilaire. I did not succeed in obtaining a specimen, but saw a living example afterwards in the possession of a shop keeper at Santarem. It seems to occur nowhere else except in the dry woods bordering the campos in the interior parts of Brazil. Altogether I thought it the prettiest species of its family I had yet seen. One would mistake it at first sight for a kitten, from its small size, varied colors and the softness of its fur. It was a most timid creature, screaming and biting when any one attempted to handle it ; it became familiar, however, with the people of the house a few days after it came into their possession. When hungry or uneasy it uttered a weak querulous cry, a shrill note, which was sometimes prolonged so as to resemble the stridulation of a grasshopper.” Callithrix albicollis (Spix).

Skull lacks backward extension, such as exists among the species of Saimiri; canines small ; angle of mandible only moderately expanded. The Titi Monkeys, as the members of this genus are usually called, are active creatures, but less lively than the Sapajou or Capuchins, and Bates says that C. moloch is a dull, listless animal. But according to his own account, it is agile enough in the trees. Their food consists of fruits, insects, birds’ eggs, and small birds whenever they succeed in capturing one. Their range is extensive, comprising the greater part of Brazil, and they are also natives of Colombia, Ecuador, Peru, and Bolivia. LITERATURE OF THE SPECIES. 1807.

GEOGRAPHICAL DISTRIBUTION OF THE SPECIES. Brazil is evidently the home of the members of this genus and they have a wide distribution over its territory, with representatives on the west in Colombia, Ecuador, Peru and Bolivia. In the north on the right bank of the Orinoco near the Mission of Santa Barbara, C. torquatus is found and its range is extended in the forests watered by the Rios Cassiquiare, Guaviare, Negro and Solimoens, going, accord¬ ing to Tschudi, (1. c.) in southeastern Peru as far as Latitude 12°. On the Upper Amazon in the forests of Olivenga near the Rio Solimoens and thence to Peru (Tschudi), its near relative C. amictus occurs. At 238 C ALLICEBU S Urucurituba, Santarem, on the Lower Amazon, C. hoffmannsi was procured, and from near the last mentioned town, C. remulus was obtained, and from Para C. emili.® was received. On the east coast from the Rio St. Mattheus to Sertem de Bahia C. melanochir is met with; and on the banks of the Rio Para near the mouth of the Rio Tapajos, and also according to Schlegel (1. c.) at Aveyros on the Lower Amazon, C. moloch dwells. Near Ilheos south of Bahia C. gigot has been procured, and this species goes as far to the south as New Frei- bourg (Schlegel), between the Rio Parahyba and the mountains to the north of the Bay of Rio de Janeiro. Near the last named city extend¬ ing northward to the banks of the Rio St. Mattheus (Wied), and on the Rio Doce C. personatus ranges, and according to Tschudi, (1. c.) it is also found in Peru between 12° and 14° South Latitude. In the Provinces of Minas Geraes and Rio de Janeiro C. nigrifrons ranges. The most southern locality for any member of the genus is Chaco in Paraguay, where C. pallescens has been taken. On the middle Amazon near Teffe or Ega, C. egeria occurs; while at the Falls of Bonaneira, Rio Marmore, C. brunneus was procured ; and near Borba on the Rio Madeira, C. caligatus was obtained. On the Rio Solimoens and thence into Peru in the forests of the Rio Ucayali and Rio Huallaga, also on the Rio Copataza, and at Andoas in Ecuador, C. cupreus occurs, and on the banks of the Rio Potomaico, on the borders of Peru, C. cinerascens was procured. From some unknown locality, supposedly in Brazil, C. ustofuscus came. In Colombia near Bogota C. ornatus was met with. At Andoas, on the Rio Pastasa in Ecuador, C. PjENulatus occurs, and also in the same State its locality unknown, C. leucometopa was obtained. Finally in Peru, at Pachite on the Rio Ucayali, C. subrufus occurs, and in the Province of Sara, Central Bolivia, C. donacophilus is found. As may be seen from the above recapitulation, the entire range of a number of species is not yet known, and doubtless, in numerous instances, they are considerably greater than those given.

Ex type British Museum. This species is nearest to C. cupreus but is altogether different in color, being darker in all its hues. The skulls also are not at all in accord, the differences mentioned being very conspicuous when a com¬ parison is made. The unique example is in the British Museum Collection, and all that is recorded of its history is that it came from Brazil, collected by Castelnau. Callicebus cupreus (Spix).

Ex specimen Brit. Mus. There is some variation among individuals of this species, and some have the upper parts a uniform Vandyke brown, palest on the center of the back, without the annulations so characteristic of the typical style; the tail also is mixed ochraceous buff and black with a buffy tip, the rest of the pelage however, being coppery red as in the others. Specimen in Paris Museum marked Callithrix discolor I. Geoff, et Deville, type, cannot be separated from the present species. It is somewhat faded in the lighter colors, but otherwise resembles C. cupreus. There are several examples in the Munich Museum obtained by Spix and all marked ' Type ! From one of these my description was taken. Mr. E. Bartlett, (1. c.) says that this Monkey is equally dis¬ tributed, but not so numerous as Saimiri ustus, in fact it may be regarded as rather rare, that is in eastern Peru. He procured it at Cashiboya on the Ucayali and at Santa Cruz on the Huallaga. Callicebus caligatus (Wagner). Callithrix caligata Wagn., Wiegm., Archiv., I, 1842, p. 357 ; Id. Schreb., Saugth.

Ex British Museum specimen. This species has been usually attributed to the Prince of Wied, and Kuhl himself attaches the Prince’s name to the one he gives the species. But the ‘Beitrage’ in which the Prince’s description is found, was published six years after Kuhl’s work appeared, and even if he took a MS. name given by the Prince to the species, it would stand as Kuhl’s who first described it in 1820.

Ex type British Museum. The type which represents the species in the British Museum Col¬ lection is a young adult with the teeth entirely unworn. In various respects it resembles C. hoffmannsi and it comes from the same place, Santarem, but the gray hands and feet, and rufous under parts easily distinguish it. It is desirable to have more specimens so as definitely to determine whether two species of this genus really are found in practically the same locality, or whether age and sex may not account for the different coloring in the types of C. remulus and C. hoff¬ mannsi. The type of the present species is much smaller than that of C. hoffmannsi as would be expected considering the difference of age. Caelicebus donacophilus (D’Orbigny).

At Aveyros on the Amazon, Bates (1. c.) met with this species, the only monkey in that locality, and which was called by the Indians Thacapu-sai. Although allied to the Cebi he found that it possessed none of their restless activity, but was dull and listless. It goes in small flocks of five or six individuals, and runs along the main boughs of the trees. He obtained an individual one morning at sunrise on a low fruit tree behind his house, the only instance in his experience of one being captured in such a situation, for it must have descended to the ground and walked some distance to reach it. Though kept as a pet by the natives, it is not very amusing and does not live long in captivity. Caelicebtjs cinerascens (Spix). Callithrix cinerascens Spix, Sim. et Vespert. Bras., 1823, p. 20, pi.

Measurements. Total length, 865; tail, 465; foot, 90. Ex type Munich Museum. There was no skull. The above description was taken from the specimen labelled as Spix’s type in the Munich Museum. As will be noticed it bears no resemblance whatever to the figure on plate XIV of Spix’s work, and is generally quite different from his description, at the same time it is not like any of the described species of the genus. In general appear¬ ance it is a reddish brown animal with nearly all the hairs tipped with grayish white, and most of them with a subterminal black ring. The tail appears black with a red tip. I have never seen a gray or ashy Callicebus like Spix’s figure, and doubt if one exists in any collection. If the present example in the Munich Museum is really the type of C. cinerascens the general idea of its appearance will have to be changed from Spix’s figure of an ashy gray animal, to a reddish brown one speckled with grayish white. If Spix’s draughtsman intended to represent the present type by the figure on plate XIV, he made a grievous failure. The type specimen is unique. Spix’s descrip¬ tion is as follows : “Ce singe a presque le taille du Saimiri. Son occi¬ put et le dos sont d’un gris rougisseant, l’avant front, les quatres pieds et le dessous du corps d’un gris de souris, et la queue noiratre. La tete est tres allongee, la face aigue, brunatre, nue sur les sourcils et sur le nez, et du reste vetue de petits poils cendres, entremeles de quelques poils roides noirs ; des poils plus longs, cendres, rayonnent autour l’exterieur de la face presque jusqu’a la gorge ; les poils du corps ne sont pas si longs comme chez les autres especes de ce genre. Les oreilles sont un peu tronquees, nues en dedans, et tres pelues en dehors. Les mains et les pattes porte la meme couleur que la reste des pieds; les dents et les ongles ont presque la meme forme que ceux de la prece- dente espece, (C. amictus). J’ai trouve ce singe dans les forets de la riviere Potomaio ou Iga aux frontieres du Perou.” 254 C ALLI C EBU S Callicebus NIGRIFRONS (Spix) . ie , Callithrix nigrifrons Spix, Sim. et Vespert.

The above description taken from Spix’s type will hardly answer for the figure on Spix’s plate, which does not represent the species, nor agree with his description. The various descriptions in Spix’s volume, should have the chief attention, and species be determined by them, for not a few of his figures are quite unlike the types, (making all allow¬ ance for the lapse of time and possible discoloration of the specimens), and would certainly mislead an investigator trying to determine his material. There is a certain amount of variation in coloring existing among examples of this species, and some do not have the black stripe on forehead to reach the ears, and the apical half of the tail is much lighter, being at times cream buff.

Head pyramidal; body thick, heavy; face naked; chin bearded; tail long, prehensile, naked at tip ; thumb opposable. Skull : braincase depressed; occipital region truncate; angle of mandible enormously developed ; lower incisors vertical ; canines rather strong ; claws convex, powerful ; hyoid greatly inflated. This subfamily has but one genus, embracing the largest species of monkeys found in the New World. Their body is thick-set and heavy, the mandible at the angle is very deep and massive, the throat is large and thick, and the larynx extraordinarily developed. The basihyal is greatly enlarged, and is expanded into a bony capsule which is lined by a continuation of the thyroid sac, and so the animal is able, by means of this peculiar formation, to produce the great volume of sound for which it is noted, and from which the trivial name of Howling Monkey is derived. The tone is deep and far reaching, resounding through the forest for an estimated distance of three miles. The tail is long and prehensile, but partially naked, and while of considerable advantage to the animal for grasping, does not attain the sensibility and extreme mobility of the same organs of the species of Ateleus, whose tails are equal in their service to a fifth hand. The thumb of the Howling Monkey is well developed and opposable. The face is naked, and a heavy beard hangs beneath the chin, especially thick in old males. Their movements are slow and their tempers sullen, and the animal is practically untamable and soon dies when held in cap¬ tivity. Their intelligence is of a very low order, and altogether the animals of this genus are among the least attractive of the Primates. VOLUME I. PLATE XXIX. Alouatta BEELZEBUL. No. 4. 7. 4. 3. Brit. Mus. Coll. 34 Nat. Size, A LOU ATT A 259 The majority of the species are black or partly so, although six are clothed in fur exhibiting shades varying from straw color to dark red. In some species the sexes are alike in color, in others quite different, and the young of some resemble their parents, while those of others are totally unlike the adults, and they can therefore be arranged in two groups. The fur is short on the bodies of some species, quite long on others, but is usually thickest on the head. Wallace (1. c.) writing of the Howling Monkeys, under the genus Mycetes, on the Lower Amazon, states that they are generally abun¬ dant; the different species, however, are found in separate localities, ( M .) beelzebul being confined apparently to the Lower Amazon in the vicinity of Para; a black species, ( M .) caraya to the Upper Amazon, and a red species, (M.) ursina to the Rio Negro and Upper Amazon. Much confusion seems to exist with regard to the species of Howlers, owing to the difference of color in the sexes of some species. The red and black species of the Amazon, however, are of the same color in both sexes. These animals are semi-nocturnal in their habits, uttering their cries late in the evening and before sunrise, and also on the approach of rain. Humboldt observes that the tremendous noise they make can only be accounted for by the great number of individuals that unite in its production. His own observations, and the unanimous testimony of the Indians, prove this not to be the case. One individual only makes the howling, which is certainly of a remarkable depth and volume and curiously modulated, but on closely remarking the suddenness with which it ceases and again commences, it is evi¬ dent that it is produced by one animal, which is generally a full grown male. On dissecting the throat, much of our wonder ceases, for besides the bony vessel formed by the expansion of the “Os hyoides,” there is a strong muscular apparatus which seems to act as a bellows in forcing a body of air through the reverberating bony cavity.

GEOGRAPHICAL DISTRIBUTION OF THE SPECIES AND SUBSPECIES. The members of the genus Alouatta are found from the State of Vera Cruz, Mexico, on the north, through Central America and the Island of Coiba to the Province of Corrientes, Brazil, on the south, and westward to Colombia, Ecuador, Peru and Bolivia. Our knowledge of the ranges of the Brazilian species of this genus is only partial, as it is also of the other Primates inhabiting that Republic, for in the interior of that great country there are thousands of miles of mountains and forests where no white man has ever pene¬ trated, and whose faunae are quite unknown. Also, when Collectors have failed to bring specimens back with them, it is at times impossible to determine what are the species they refer to in their publications, and errors of distribution can therefore easily be made. In Brazil, in the interior, we have practically no knowledge of the animals which inhabit the dense forests at any considerable distance from the rivers, for explorers have penetrated, in most instances, but a few miles from their banks, and how far a known species may range is, in many cases, quite impossible to state. Therefore in giving the range of most of the South American species of Primates, we are restricted to the places where they have been obtained, or seen by reliable and com¬ petent observers. To begin at the most northern point where a species of Alouatta dwells, we find, in the eastern portion of the State of Vera Cruz, Mexico, A. palliata mexicana, the only species of the genus inhabiting that Republic. In Guatemala, Central America, A. villosus occurs, extending its range into Honduras; while in Nicaragua we have A. palliata, which is also an inhabitant of Costa Rica and Panama. On 264 ALOU ATT A Coiba Island, off the west coast of Panama, A. p. coibensis has been procured. On the Island of Trinidad one species dwells, A. insu- lanus ; and in the British and French Guianas, and probably also in Dutch Guiana, (though no examples from there were obtainable), to the coast north of the Amazon, A. macconnelli has been obtained. In Venezuela in the forests of the Lower Orinoco, (Humboldt), and in the maritime Provinces of Brazil from Bahia to Espirito Santo, A. ursina occurs, and also according to Tschudi, under the name of Mycetes davicaudatus it is found in Peru, in which case it must necessarily inhabit the intervening portions of Brazil. From the vicinity of Para, on the Rio Muria (Natterer), and between the Rio Xinges and Island of Marajo, (Spix), on the Rio Araguay, (I. Geoff.), and in the vicinity of Borba near the mouth of the Rio Madeira, (Natterer), A. beelzebul occurs. Bates states that the natives assert there is a “yellow handed” monkey on the Island of Marajo, which may be this species. On the Lower Amazon in Maranhao A. ululata appears to have its range. Proceeding on in eastern Brazil, A. caraya ranges from the Province of Bahia to that of Corrientes in Argentina ; having been observed in the low forests of Bahia and Minas Geraes (Spix), in the Province of Goyas, (Castelnau), and on the Upper Rio Paraguay, and near the town of Matto-Grosso (Natterer), and also at the junction of the Rio Parana and Rio Paraguay, Argentina, (Rengger). On the Rio Juara, a tributary of the Upper Amazon, A. juara has been obtained. In Colombia, A. seniculus is found, and according to Spix who obtained a specimen, it also occurs in the forest between the Rio Negro and Rio Solimoens, his example having been secured near the borders of Peru. In Ecuador at Vinces on the west coast A. a£Quatorialis was procured; and finally, in Bolivia in the Province of Sara, A. sara occurs. KEY TO THE SPECIES. A.

Hair long, thick, divided by a central line on the head, and falling down partly covering the face ; thick beard on the chin ; ears large ; tail long, thick, bushy, non-prehensile. Incisors of both jaws project forwards, the inner pair larger than the outer which are very small; canines long, conical; first premolar the smallest and with only one cusp; molars with grooved crowns, and four cusps. The members of this genus are peculiar in having the body usually covered by long, coarse hairs. The tail, which is longer or as long as the body, is also covered with a similar coarse hair, being in certain species quite bushy. Another peculiarity is the thrust forward of the incisors both of the upper and lower jaws. In the brain the cerebellum and olfactory lobes are covered by the cerebrum, and the ribs are broad and consist of twelve pairs except P. pithecia which has thirteen. They are timid and very delicate creatures, usually surviving but a brief period in captivity, and become much attached to whoever cares for them. These monkeys are found in the Guianas, the forests of the Orinoco and its tributaries, and the valley of the Amazon, extending their range westward into Ecuador and Peru. Eight species are here recognized. LITERATURE OF THE SPECIES. 1766. Linnaeus , Systema Nature?. Pithecia pithecia first described as Simia pithecia. 1777. Erxleben, Systema Regni Animalis.

Gray, in Proceedings of the Zoological Society of London. Four species are here given. P. chrysocephala ; P. monacha, with P. irrorata Gray, as a synonym ; P. rudventer = P. pithe- cia, with P. pogonias Gray, as a synonym; and P. albicans described for the first time. Two others are mentioned as ap¬ parently distinct, P. leucocephala Geoff., = P. fithecia ; and P. albinasa. These had not been seen by this Author. 1862. Reichenbach, Die Vollstdndigste Naturgeschichte der Affen. In this work the species of Pithecia are divided between that genus and Yarkea as follows: P. rudventer = P. pithecia; P. capillimentosa ; P. chrysocephalus ; (F.) leucocephala = P. pithecia; (F.) ochrocephala = P. chrysocephala; (F.) inusta = P. pithecia; and (F.) irrorata = P. pithecia; B. israelita Gray = P. chiropotes as does also C. sagulata Gray. 1870. /. E. Gray, Catalogue of Monkeys, Lemurs and Fruit-eating Bats, in British Museum. The species of Pithecia are here divided into two Tribes, Pithecina and Brachyurina. The first contains the genus Pithe¬ cia with four species, viz.: P. albicans; P. rudventer — P. pithecia; P. leucocephala = P. pithecia; and P. monacha. Brachyurina has two genera Chiropotes, with (C.) satanas; (C.) sagulata = P. chiropotes; (C.) ater = P. satanas; and (C.) albinasa. The second genus Ouakaria has three species, all of which are now included in the genus Cacajao. 1876. Schlegel, Museum d’Histoire Naturelle des Pays-Bas, Simice. In this work nine species are placed in the genus Pithecia, viz., P. nocturna = P. chrysocephala Geoff., which is con¬ sidered a variation from the typical style. Simla pithecia Linn., is given among the synonyms, but, although it has a prior claim, is not adopted as the name of the species. P. mona¬ cha; P. albinasa; P. chiropotes; P. satanas; P. melano- cephala, P. calva, P. rubicunda and P. alba, the last four not belonging to Pithecia, but now contained in the genus Caca¬ jao, but P. alba is a supposititious species no example having ever been procured. 1883.

Five species of Pithecia are here recorded as follows : P. leu¬ cocephala Audeb., = P. pithecia Linn.; P. chrysocephala; P. hirsuta = P. monacha; P. chiropotes; and P. satanas. 288 PITHECIA GEOGRAPHICAL DISTRIBUTION OF THE SPECIES. On the northeastern corner of South America in French Guiana, two species of this genus are found, one P. capillimentosa not having been, as yet, procured elsewhere ; the other P. pithecia with a wider known range, being a resident of British Guiana for 300 miles into the interior, (Sclater, Proc. Zool. Soc. Lond., 1866, p. 305) ; and Guiana possesses two additional species, P. satan as and P. chiropotes, rang¬ ing on the Upper Orinoco, Rio Tocantins and Rio Negro; the first named having been obtained at Para ; the latter also on the Rio Branco, Brazil, and, according to Bates, it goes to Peru. On the Upper Amazon near Ega on the Solimoens P. albicans was procured, its range unknown; and on the banks of the Rio Negro near Barra P. chrysocephala occurs. At or near Santarem on the Lower Amazon P. albinasa was found. The most extensive known range of any of the species is that of P. monacha, which occurs on both banks of the Upper Amazon, on the Rio Negro, Rio Madeira and Rio Marmore, in the vicinity of Tabatinga on the Rio Solimoens, and into Peru, where it has been procured on the Rio Javari and Rio Ucayali. The species has also been obtained on the Rio Marona in Western Ecuador. KEY TO THE SPECIES. A. Size large. o. Hair of head long, projecting forward on face. a.'

The type of Pithecia inusta Spix, is in the Munich Museum and can in no way be separated from P. monacha. It is a full grown animal in good condition and came from the forests of the Tonantins, an affluent of the Solimoens River, near Tabatinga. Bates, writing about this monkey under the name of Paranacu (1. c.) states that it is a timid, inoffensive creature, and is found on the “terra firma” lands of the north shore of the Solimoens from Tonantins to Peru. It is a very delicate animal rarely living in cap¬ tivity for any length of time, but if one succeeds in keeping it alive for any considerable period, it makes a very affectionate pet. While the Cebi exceed all the American monkeys in intelligence, the Coaita, (Ateleus paniscus) has the most gentle and affectionate disposition, but the Paranagu although a dull, cheerless animal exceeds all in its capability of attachment to man. It is not lacking in intelligence, as the following incident shows. A neighbor had gone out in the morn¬ ing leaving his pet behind, and the monkey missing its friend decided it would come to Mr. Bates as was its habit, and so the Paranagu took a short cut over gardens, trees and thickets, as a neighbor saw it on its way, and came directly to Mr. Bates’ dwelling. Not finding its master there, it climbed on to a table and sat down, and with an air of quiet resignation waited for him. Soon after its owner entered and his pet jumped at once to its usual perch on his shoulder. PITHECIA 291 PlTHECIA CAPILLIMENTOSA Spix. Pithecia capillimentosa Spix, Sim. et Vespert.

Measurements. Total length, 475; tail, 220; foot, 90. Skull in specimen. Ex type Munich Museum. The type is a young animal, perhaps half grown, and has gener¬ ally been considered the same as Pithecia pithecia (Linn.). It is, however, much nearer P. monacha (Humboldt), but differs from that species in its jet black hands and feet, and in having the buff on the under parts extending to the lower part of the abdomen. Compared with a young P. monacha of about the same size and probably age, it differs in the much longer hairs on the head and neck rising, as Spix states, like a wig, (but not shown in his plate), in the much greater extent of the buff color on the under parts, and strikingly in the totally different color of the hands and feet, as there is no indication whatever of the grayish or yellowish white hue which makes the hands and feet of P. monacha so conspicuous a feature of that species. There seems to be no alternative but to consider Spix’s type as representing a dis¬ tinct form. Like so many of Spix’s figures, the one given of this type does not represent the animal either in color or in the length and peculiar disposition of the hairs. Spix did not collect this specimen, but found it in the collection of the Munich Museum, and it was in the register of 1816 as having come from Cayenne. This is on one of the tickets now attached to the type. Of course this was before Spix made his journey to Brazil. He does not say in his work what the locality of his type was, but merely gives a description of the animal and a figure. 292 P1THECIA Pithecia albicans Gray. , 10,n . Pithecia albicans Gray, Proc.

Hair long and loose hanging down the sides to knees and elbows; tail long, bushy; hair on back of head leaning forward, forming a hood as in P. monacha. Color. Face covered with short white hairs ; head, shoulders, sides of body, limbs, hands and feet whitish ; back, upper part of sides and tail black, the hairs with whitish tips ; under parts russet ; hands and feet whitish or grayish. Ex type in British Museum. Measurements. About the size of P. monacha. The type and paratypes of this form described by Gray are in the British Museum Collection, and seem entitled to be regarded as distinct. They differ in color from all other Pithecise. The adult does not agree with Gray’s description for the shoulders and arms are not black, but whitish, the black of the back only covering the back between the shoulders, and there is no black whatever on the arms. The ‘whitish’ of Gray’s description has now become a pale, dirty, yellowish brown, probably giving a very incorrect idea of the animal’s appearance in life. The hairs on hands and feet are quite short, the long hairs not going beyond the wrists and ankles. The long hair of the head comes forward to the face as in P. monacha, but the texture is quite different from the hair of that species, being not harsh and straight but having an inclination to curl. Bates, to whose book I have so often referred, says, (1. c.) that this monkey is found on the banks of the Teffe south of the Solimoens. An individual, since placed in the British Museum, was a pet of a young Frenchman at Fga. It was so tame that it followed him like a dog about the streets. Its owner was a tailor, and the monkey passed most of the day on his shoulder while he was at work. It was not friendly, however, to any other person. PITHECIA 293 Pithecia PITHECIA (Linnaeus).

Gray (1. c.) refers his P. leucocephala to P. chrysocephala Geoff., having never seen the type specimen and considers Geoffroy’s P. leucocephala as distinct. In this he was mistaken, as both Gray’s and Geoffroy’s leucocephala are the same, and not separable from P. pithecia Linn. In the same paper, Proc. Zool. Soc. Lond., 1860, he refers his P. irrorata correctly to P. monacha. There are two specimens in the Paris Museum marked P. ruh- venter but neither are marked “Type,” and the whereabouts of that important example is unknown. The type of Pithecia pogonias Gray, is in the British Museum. It is a female with the red belly, and in all respects resembles the females of P. pithecia. A specimen in the Paris Museum marked “Type” on the label, and on the bottom of the stand, “leucocephalus G. St. H.” is probably Audebert’s type which is exactly the same as S. pithecia Linn. It is a male. Pithecia chrysocephala I. Geoffroy. Pithecia chrysocephala I. Geoff., Compt. Rend., 1850, p. 875 ; Id. Cat. Primates, 1851, p. 55; Id. Archiv. Mus. Hist. Nat.

Ex specimen from Rio Negro in British Museum called leucocephala. This species varies considerably both among adult individuals and also at different ages ; the young being more or less reddish brown and the females resembling young males, reddish brown hairs tipped with buff in the color of their pelage, with a white band bordering the front of the cheek. Kuhl’s types of P. ochrocephalus and P. rufibarbata are both in the Leyden Museum and both are immature. P. ochrocephalus has begun to assume the black pelage on different parts of the body, especially on the limbs, the hairs of which are tipped with ochraceous ; and the hairs around face and on front of head are buff, probably faded, and much paler than the adult P. ochrocephalus. P. rufibarbata is a very young animal about half grown and completely in the brown pelage. Pithecia albinasa I. Geoff roy et Deville. Pithecia albinasa I. Geoff, et Deville, Compt.

Skull : parietal and malar bones in contact ; mandible dilated posteriorly, similar to that of the members of the genus Alouatta; incisors oblique; diastema present between canines and incisors of the upper jaw. The three species comprising this genus are the only short-tailed monkeys inhabiting the New World. The brevity of this organ is not occasioned by the fact that fewer vertebrae are present, but on account of their small size. Two of the species are remarkable for the brilliant coloring of their faces, which are scarlet or vermilion-red, and this hue becomes much deeper whenever an individual is excited. The brain is well developed and complicated, very different from that of the species of Saimiri. The lower jaw is peculiar in shape resem¬ bling somewhat that of the species of Alouatta, but there is no especial relationship between the genera. In their distribution each species of Uakari monkey is restricted to a certain district, and although the ranges of two of them, C. calvus and C. rubicundus, approach rather closely at one point, they are not known ever to mingle together. Bates, who had very good oppor¬ tunities for observing these animals in their native land, states, writing of them in a general way, that they live in forests which are inundated 300 CACAJAO during a great part of the year, and they never descend to the ground , the short tail being no evidence of terrestrial habits such as those of t e short-tailed Baboons of various genera. LITERATURE OF THE SPECIES. 1812. E. Geoffroy St. Hilaire, in Annales du Museum d’Histoire Naturelle, Paris. Cacajao calvus described as Brachyurus calvus, and C. melanocephalus as Pithecia melanocephala. 1823. Spix, Simiarum et V es pert ilionum Brasiliensium. Under the genus Brachyurus two species are given : C. melano¬ cephalus redescribed as B. ouakary; and B. israelita — Pithecia chiropotes E. Geoffroy. 1840. R. P. Lesson, Species des Mammiferes Bimanes et Quadru- manes. Two forms recognized by the Author are placed in Cacajao, but this is made a subgenus of Pithecia. The species recog¬ nized is C. melanocephalus with “variete d’age” ? B. ouakary Spix, = C. MELANOCEPHALUS. 1845. E. Geoffroy Saint-Hilaire, in Archives du Museum d’Histoire Naturelle, Paris. Two species are here first described under the genus Brach¬ yurus: B. rubicundus, and B. calvus. 1862. Reichenhach, Die Vollstandigste Naturgeschichte der Affen. Cacajao here contains C. ouakary — C. melanocephalus ; and C. melanocephalus ; the remaining species being included in Brachyurus: ( B .) rubicundus and ( B .) calvus. 1870. /. E. Gray, Catalogue of Monkeys, Lemurs and Fruit-eating Bats, in Collection of the British Museum. In this List the three species above described are placed in a new genus ‘Ouakaria.’ Individuals varying in white or red hues are considered as albinos of C. melanocephalus ! 1876. Schlegel, Museum d’Histoire Naturelle des Pays-Bas, Simla:. Three species already described are here placed in the genus Pithecia, and a supposed white form from the banks of the river Japura, represented only by an uncolored drawing in Bates’ book, “The Naturalist on the River Amazon,” (no specimens from that locality having been seen), is described as Pithecia alba = Cacajao calvus. CACAJAO 301 GEOGRAPHICAL DISTRIBUTION OF THE SPECIES. The dispersion of the species of this genus is given in the articles as described by Bates in the passages quoted. Briefly it may be said that C. calvus is confined to the west side of the Japura River near its mouth; to the banks of the Uatiparana near Tonantins; C. rubi- CUNDus inhabits the eastern half of the western part of the Japura delta, an extent of country 150 miles long by 60 or 80 wide, and C. melanocephalus is found 180 miles from the mouth of the Japura according to Bates, but Humboldt says it is met with in the forests watered by the Cassiquiare, Negro and Branco rivers.

Young. Bates writes of the young (1. c.) p. 313, “I was surprised to find the hair of the young animal much paler in color than that of the adults, it being of a sandy and not brownish red hue, and con¬ sequently did not differ overmuch from that of the white species, the two forms therefore are less distinct from each other in their young than in their adult states.” Measurements. Skull : occipito-nasal length, 85 ; zygomatic width, 64; intertemporal width, 41.5; palatal length, 32; width of braincase, 52; median length of nasals, 16; length of upper molar series, 20; length of mandible, 58; length of lower molar series, 23. Vertebrae: Cervical, 7; Dorsal, 13; Lumbar, 6; Sacral, 4; Caudal, 15 to 20. The type in the Paris Museum is so faded that it will no longer serve for comparison of colors. Bates says of this species, (1. c.) under the trivial name of ‘white Uakari/ that it is only found on the banks of the Japura River near its principal mouth, and is confined, so far as he was able to ascertain, to its western side. It goes in small troupes, in the tops of the highest trees, and subsists on various kinds of fruits. The hunters say, while nimble in its movements, it does not often leap, but runs along the larger limbs when travelling from tree to tree. The young are carried on the back of the mother. The Indians shoot them with poisoned arrows, and they go a considerable distance after being wounded, and an experienced hunter is required to follow them. The most expert hunter is he who can keep up with a wounded Uakari, and catch it in his arms when it falls exhausted. If then he wishes to keep the animal alive, a pinch of salt, the antidote for the poison, is put into its mouth and it revives. These monkeys are in great demand for presents, and high prices are asked for them, often as much as the equivalent of nearly twenty dollars. Adult Uakaris taken in the above manner rarely become tame, remaining peevish and sulky and bite every one who comes near them, and are quite silent in captivity, and in the course of a few days refuse to eat and die. Many succumb to inflammation of the lungs. One he CACAJAO 303 had as a pet died of this malady. Although kept in an airy veranda, it soon lost its appetite ; its coat which was long, smooth and glossy, became dingy and ragged, like museum specimens, and its bright scarlet face became dull. When in health, this color extends to the hair on the forehead and temples, and over the cheeks and jaw to the neck. As their hue remained for several hours after the animal’s death, he supposed it was due, at least partly, to a pigment beneath the skin, which would probably retain its color after the circulation ceased. After witnessing so many proofs of this monkey’s morose disposi¬ tion, he was to meet a very lively individual at the house of a friend. It came from an adjoining room, ran to him and climbed into his lap and nestled there, looking up at him and grinning in the way monkeys have. It was young, and had been captured after its mother had been shot. Its teeth were still incomplete and its face was pale and mottled, the scarlet hue of the adult not having yet appeared. It had been reared with the children and allowed to run about the house. The Uakari is one of the many animals the Brazilians call “mortal” or with delicate constitutions in contradistinction to those which are “duro” or hardy. Most of those sent from £ga die before reaching Para, and the difficulty it experiences in accommodating itself to changed conditions probably influences its restricted range, for its limit is an area of swampy woods of about sixty miles in extent, without any barrier to prevent it from wandering farther, except towards the south. One, which he had on his boat on the Rio Negro, and which was quite tame, went on shore one morning at Barra and disappeared in the forest and was gone for twenty-four hours, when he reappeared and walked down the bowsprit, his mode of departure, to his usual place on deck. He had evidently found the forest, which was very different from his humid home on the Japura, uncongenial, and preferred the boat and captivity, to freedom in such a district. Schlegel (1. c.) has given the name of Pithecia alba to the monkey described by Bates, as he considered the uncolored drawing in the book represented a distinct species from the Uakari found on the banks of the Solimoens, from the fact that the artist has represented the hair of the animal much longer than it is on the other, and because Bates speaks of it as having a shining whitish hue. It may possibly be that two nearly allied forms of Uakari do exist on these rivers, but until specimens from the two localities are obtained and compared, it is hazardous to describe one as distinct upon an uncolored drawing, and not a very meritorious one at that. It is not easy at times to recognize different species of monkeys when examples are accessible, 304 CACAJAO and it is hardly worth while to add to difficulties already existing, and which are quite sufficient to give the investigator trouble enough, without bestowing names on possible species that the describer has never seen ! I have included Schlegel’s name among the synonyms of this species, on the strength of the Scotch verdict “not proven.” The so called white Uakari is probably an immature individual of the present species.

Bates in the work from which extracts have already been taken says: ‘‘A most curious fact connected with this monkey is the existence of an allied form, or brother species, in a tract of country lying to the west of its district. This differs in being clothed with red instead of white hair, and has been described by Isidore Geoffroy St. Hilaire Volume I Plate II CACAJAO RUBICUNDUS (Head) Volume I Plate 1 0 Cacajao melanocephalus C A CAJAO 305 (from specimens brought to Paris in 1847 by the Compte de Castel- nau) as a distinct species, under the name of Brachyurus rubicundus. It wholly replaces the white form in the western parts of the Japura delta; that is to say, in a uniform district of country, 150 miles in length, and sixty to eighty in breadth, the eastern half is tenanted exclusively by white Uakaris, and the western half by red ones. The district, it may be mentioned, is crossed by several channels, which at the present time doubtless serve as barriers to the dispersal of monkeys, but cannot have done so for many centuries, as the position of low alluvial lands, and the direction of channels in the Amazon Valley, change considerably in the course of a few years. The red- haired Uakari appears to be most frequently found in the forests lying opposite to the mouth of the river which leads to Fonteboa, and ranges thence to the banks of the Uatiparana, the most westerly channel of the Japura, situated near Tunantins. Beyond that point to the west there is no trace of either the red or the white form, nor of any other allied species. Neither do they pass to the eastward of the main mouth of the Japura, nor to the south shore of the Solimoens. How far they range northwards along the banks of the Japura, I could not precisely ascertain ; Senhor Chrysostomo, however, assured me that at 180 miles from the mouth of this river, neither white nor red Uakari is found, but that a third, black-faced and gray-haired species takes their place. “I saw two adult individuals of Brachyurus rubicundus at Ega, and a young one at Fonteboa; but was unable to obtain specimens myself, as the forests were inundated at the time I visited their locality. I was surprised to find the hair of this young animal much paler in colour than that of the adults, it being of a sandy and not of a brownish-red hue, and consequently did not differ very much from that of the white species; the two forms, therefore, are less distinct from each other in their young than in their adult states. The fact of the range of these singular monkeys being so curiously limited as here described, cannot be said to be established until the country lying between the northern shore of the Solimoens and New Granada be well explored, but there can be no doubt of the separation of the two forms in the Delta lands of the Japura, and this is a most instructive fact in the geographical distribution of animals.” Cacajao melanocephaeus (E.

The Squirrel Monkeys are small animals, ranging from Nicaragua through the valley of the Amazon into Bolivia and Peru, and with their brilliant coloring are perhaps the most beautiful of their tribe. They are strictly arboreal, and as Bates remarks, are the most common of the ordinary monkeys of the American forests. By some writers they have been considered as closely related to the nocturnal monkeys, but the relationship is one caused more by environment and conse¬ quently similar methods of life than through their organization, and it may therefore be regarded in the light of being artificial. They possess large eyes, small ears, and a small inquisitive face, but they would probably make very unsuccessful hunters by night, as their vision is only adapted for daylight. Six species and two subspecies are now recognized, with fairly distinctive characters. It has been found necessary to make certain changes in the nomenclature of some forms either on account of previous names having been overlooked by some of the earlier writers, or the law of priority disregarded. There is little or no change in the appearance of the sexes, or between old and young individuals, and these causes of frequent errors in other groups being non-existent, the synonymy of the various forms is happily brief.

In this catalogue four species are recognized under the genus Saimiri: S. sciureus; S. lunulatus = S. cassiquiarensis ; S. cerstedi ; and S', entomophaga = S. boliviensis. S. ustus Geoff., is considered the same as S. sciureus. 1904. Thomas, in Annals and Magazine of Natural History. Saimiri cerstedi redescribed as Saimiri cerstedi citrinellus. 1907. Elliot, ( D .

The range of the various species is as yet but imperfectly known for several have been obtained only from a few localities, and some indeed from only one, and those given heretofore by previous writers are to some extent misleading as more than one species have been confused together and the separate ranges united. The most northern distribution of members of this genus is in Central America where S. cerstedi is found from south of the Herradura Mountains to Panama. In northern South America S. sciureus is met with in the three Guianas, Venezuela and Colombia, and to the south on both banks of the Amazon and some of its tributaries as the Rio Negro, Rio Uaupe, Rio Javari, (Schlegel), etc., and in the Province of Goyas, Brazil. S. cassiquiarensis ranges from the banks of the Orinoco south of the Cataracts to the Rio Cassiquiare, and in the forests through which the Rio Caura flows above the rapids of Mura, and thence westward to the Rio Copataza in Ecuador. From Humayta, middle Rio Madeira, also in Ecuador, S. Madeira has been procured. On the banks of the Ucayali, Peruvian Amazons, S. ustus is found and at Cosnipata in eastern Peru, S. b. nigriceps is met with. S. macrodon has been obtained from the banks of the Rio Copataza in Ecuador; and from those of the Rio Juara, and from Marcopata in Peru. S. boliviensis occurs in the Sierras Guarayas, Bolivia.

Banks of the Rio Cassiquiare, Venezuela. Geogr. Distr. Banks of the Orinoco south of the Cataracts, to the Rio Cassiquiare, and Rio Guaviare, and in the forests through which the Rio Caura flows above the rapids of Mura, Venezuela, (Hum¬ boldt). Color. Top of head and nape speckled buff and black ; line from occiput passing above ears and curving downwards, black; forehead, face, nose, chin, throat, ears and sides of neck white; dorsal region red speckled with black ; arms to elbows, and legs to ankles dark gray ; forearms, hands and feet ochraceous; under parts and inner side of 312 S AIM I R I limbs yellowish white ; tail like back at root, then iron gray for three fourths the length, apical portion black. Measurements. About the size of S. sciureus. Skull : occipito- nasal length, 60 ; zygomatic width, 37 ; intertemporal width, 32 ; median length of nasals, 10; length of upper molar series, 18; length of mandible, 15; length of lower molar series, 15. This species has been usually known as S. lunulatus Geoff., but this name is antedated by Humboldt’s cassiquiarensis bestowed on it thirty-three years previously. The whereabouts of the type does not appear to be known. Humboldt states that this Squirrel Monkey is common south of the cataracts of the Orinoco ; some are found there of a more slender form and are very difficult to tame, and also on the banks of the Guaviare River, and in the forests in which the Caura River flows above the rapids of Mura. The smallest and prettiest of the Titis are those of Cassiquiare. Schlegel says (1. c.) that an individual of this species was brought to his notice, which was procured by a French naturalist near the Oyapock, a river separating French from Portu¬ guese Guiana. Spix, according to Wagner, obtained three examples of this species, called by Wagner C. nigrivittatusl at the junction of the Teffe and Solimoens rivers near Rga, but Spix does not mention this monkey. Saimiri macrodon Elliot. Saimiri macrodon Elliot, Ann. Mag. Nat. Hist., XIX, 1907, 7th Ser., p. 190. Type locality. Copataza River, Ecuador. Type in British Museum. Geogr. Distr. Upper waters of the Amazon, Ecuador; and Rio Jurua; Marcopata, Peru. Genl. Char. Similar to S. sciureus, but hands and feet much darker. Skull has a much higher and narrower braincase ; much wider palate, and larger teeth with the external line of the upper tooth row much more curved; zygomatic arch wider; and intertemporal width, greater ; bullae narrower and longer. Color. General color like S. sciureus with the back darker, that of the type being tawny and black on the dorsal region, golden yellow and black on the flanks ; arms above elbow dark gray washed with yellow, legs paler; under parts yellowish white; arms from a short SAIMIRI 313 distance below the elbow, hands and feet tawny; head and tail like S. sciureus. Ex type British Museum. Measurements. Size similar to S. sciureus. Skull : occipito-nasal length, 64.5 ; zygomatic width, 43 ; intertemporal width, 32 ; median length of nasals, 11 ; width of braincase, 36; height of braincase above zygomata, 35; palatal length, 19; length of upper molar series, 13; length of mandible, 40 ; length of lower molar series, 16 ; width of palate between canines, 12; width of palate between last molars, 13. Ex type British Museum. While the general color of this animal resembles that of S. sciureus from the east coast of South America, it is at once noticeable by its much darker forearms, hands and feet. But the great differences between them are exhibited in the skull, and the large teeth of the present species. The braincase has quite a different shape, being large and narrow with an elevated forehead sloping rapidly downward to the occiput where it is narrow and rounded. The palate is wider throughout its length, while the teeth are much larger, the canines being also stouter and broader. Several specimens were brought by Mr. Buckley from the type locality and there are others in the British Museum Collection from the Jurua River, a tributary of the Upper Amazon, and from Marcopata, Peru.

Distr. Peruvian Amazons, Bolivia. Genl. Char. Ears naked save a fringe of hairs on the inside near the upper edge; general color golden yellow and black. Color. Upper part of head, shoulders, upper arms to elbow, and hind limbs to ankles golden yellow speckled with black, the hairs being golden yellow with black tips ; back from neck to rump orange red and black, the latter being the tips to the orange red hairs ; face around eyes and upper part of nose flesh color, muzzle black; cheeks pale yellow ; sides of head and neck, throat, under parts of body and fore¬ arms golden yellow ; hands and feet reddish brown ; tail, hairs golden yellow with black tips, the tip of tail all black. Ex type Paris Museum. Measurements. Size about equal to S. sciurea Linn. Skull : total length, 72. (Geoff. Arch. Mus.). The type of this form is in the Paris Museum and fairly well preserved, though probably the golden yellow of the greater part of the body has faded somewhat. The back, however, is conspicuous for the depth of its orange red color, and more resembles the hues of the Central American forms than any of the eastern South American examples. With our present knowledge of this group, in spite of Schlegel’s unqualified statement, (1. c.) it seems best to consider SAIM1RI 315 Geoffroy s species as distinct, until undoubted evidence is obtained to the contrary.

Face and sides of head to ears white; top of head and SAIMIRI 317 nape black ; shoulder and outer side of arms to below elbows, and legs to ankles gray washed with yellow ; upper parts dark ochraceous rufous, dorsal line dark orange rufous ; throat and between arms white, rest of under parts and inner side of limbs ochre yellow ; hands and feet ochraceous ; tail above for two thirds the length black and yellow, beneath yellow, apical portion black. Measurements. Total length, 633; tail, 363; foot, 78; ear, 24. Skull : occipito-nasal length, 56 ; zygomatic width, 36 ; intertemporal width, 30; palatal length, 15; breadth of braincase, 35; median length of nasals, 8; length of upper molar series, 11 ; length of mandible, 31 ; length of lower molar series, 13. This species was originally described from an example obtained at Chiriqui, and Dr. Frantzius states it is confined to the hotter region, being very abundant in the valley of Terraba and on the plain of Piris, and he believed its northern limit to be the spurs of the Herradura Mountains going towards the sea. A living individual was presented to the London Zoological Society by Mr. W. F. Kelley, who said it was procured in the Department of Solala, Guatemala, but no other example seems to have come from there and it is surmised that possibly Mr. Kelley’s animal may have been brought from some southern locality. Mr. Thomas has described the monkey from Pozo Azul, Costa Rica (1. c.) as a distinct race under the name of A. cer. citrinellus, the chief character being the head “less blackened and the limbs less yel¬ low.” A series of these monkeys from Panama collected by J. H. Batty and two specimens from Pozo Azul collected by M. A. Carriker, belonging to the New York Museum of Natural History are before me. In the Panama series every style of head coloring from jet black to gray is represented, some almost exactly like the examples from Pozo Azul, and the difference in coloration would seem to be due to age, the old adults having intensely black crowns, and this passing through all grades of coloring to the young animals with little or no black on the head. The type of Y. cer. citrinellus in the British Museum has less black on the head than the old adults, and it does not go so far on the occiput, but other specimens from the same localities in the Museum collection have black crowns, and it does not seem that a dis¬ tinct race can be sustained, knowing, as we do, the great diversity of head coloring that exists at different periods of the animal’s existence. I have therefore placed S. cer. citrinellus as a synonym of S. cerstedi. . ■ ' INDEX OF LATIN NAMES. VOLUME I. Numbers in heavy type indicate the page on which is the description of the Species.
