UNITED STATES NATIONAL MUSEUM. PROCEEDINGS OF THE S UNITED STATES NATIONAL MUSEUM. Neolmnve <2O hv . PUBLISHED UNDER THE DIRECTION OF THE SMITHSONIAN INSTITUTION. WASHINGTON : GOVERNMENT PRINTING OFFICE. 1902. in “=~? ADVERTISEMENT. The publications of the National Museum consist of two series: Proceedings and Bulletins. The Proceedings, the first volume of which was issued in 1878, are intended primarily as a medium of publication for newly-acquired facts in biology, anthropology, and geology, descriptions of new forms of animals and plants acquired by the National Museum, discussions of nomenclature, etc. A volume is issued annually for distribution to libraries, while in view of the importance to science of the prompt publication of descriptions of new species, a limited edition of each paper is printed in pamphlet form in advance. The present volume is the twenty-fourth of the series. The Bulletin, publication of which was begun in 1875, is a series of elaborate papers, issued separately and based for the most part upon collections in the National Museum. They are monographic in scope, and are devoted principally to the discussionof large zoological groups, bibliographies of eminent naturalists, reports of expeditions, ete. A quarto form of the Bulletin, known as the ‘‘ Special Bulletin,” has been adopted in a few instances in which a larger page was deemed indispensable. The Annual Report of the National Museum (being the second vol- ume of the Smithsonian Report) contains papers chiefly of an ethno- logical character, describing collections in the National Museum. Papers intended for publication by the National Museum are usually referred to an advisory committee, composed as follows: Frederick W. True (chairman), William H. Holmes, George P. Merrill, James E. Benedict, Otis T. Mason, Leonhard Stejneger, Lester F. Ward, and Marcus Benjamin (editor). S. P. LAaneiry, Secretary of the Smithsonian Institution.

By Davip Starr JORDAN and JOHN OTTERBEIN SNYDER, Of the Leland Stanford Junior University. The present paper contains a review of the Hypostomide and Lopho- branchiate fishes of Japan, the families Pegasidee, Solenostomide, Syngnathide, and Pegasidee. It is based on specimens obtained in Japan by the authors in the summer of 1900, a series of duplicates being in the United States National Museum, and upon the collection of Japanese fishes in the United States National Museum, as well as upon specimens collected by the United States Fish Commission Steamer ° Albatross. In this work we have had the efficient aid of Mr. Michitaro Sindo, who has carefully compared and measured all the recorded specimens. Suborder HYPOSTOMIDES. Body covered with bony plates, anchylosed on the trunk, movable on the tail. Gill cover formed by a large plate corresponding to the opercle, preopercle, and subopercle. One rudimentary branchiostegal. Gills four, lamellated: Ventral fins abdominal. Dorsal and anal short, of soft rays only. No pseudobranchivw or air-bladder. This group contains a single family; fantastic little fishes of the Asiatic seas. [ (v0, below; @TO“a, mouth.) Family 1. PEGASID. Body broad, much depressed, covered with bony plates; mouth small, below a prolonged snout, its margin formed by the premaxil- laries; no teeth; suborbital ring well developed, forming a suture with the gill cover. Pectorals broad, very laree, placed horizontally; ventrals well behind the pectorals, not far from the vent, of one or two rays, one of them very long; tail four angled, the short dorsai PROCEEDINGS U.

ZALISES Jordan and Snyder, new genus Zalises JORDAN and SNYDER, new genus (draconis). The genus contains those species of Pegasidw which have the tail short and not attenuate and compressed toward the tip, and in which the pectoral rays are all slender and simple, none of them spine-like.

Head 2% in length; width, posterior to pectorals, 33. D.5; A. 5; P.10; V.2. Vent midway between front of eye and base of caudal fin. Tail of 8 rings. Trunk gibbous, the median depressed part divided by three cross-ridges; obtuse tubercles at the meeting points of the lengthwise and cross ridges of the back; nape with two deep pits; first, second, fourth, and fifth tail rings each with a compressed spine directed backward; pectoral 3 in body, as long as from tip of snout to nuchal pits; fifth pectoral ray not enlarged; snout prolonged, longer than in any other species, its length from eye 5 in body, the part before the mouth more than twice as long as broad, with a finely serrated edge on the dilated blade on each side; distance from middle of shoulder girdle to tip of snout, 24 in total length (84 in P. draconis). Color brownish, finely marked with darker. The snout and the last two caudal rays black; pectoral with fine brown dots on the rays, the outer part of the fin paler. Seas of Japan, here described from a dried specimen, 75 millimeters long, from the province of Kili (Wakanoura), presented by the Imperial Museum of Tokyo. Type.—No. 6518, Leland Stanford Junior University Museum. The species closely resembles 2. draconis of the East Indies, but differs from descriptions and figures in the longer and narrower snout, and rather longer tail. Other specimens supposed to be the same are in the collection from Boshu (near Misaki), and another from Kii. (Umi, sea; Tengu, a long-nosed god of a humorous nature, in Jap- anese mythology.) 'The fifth pectoral ray is enlarged and spine-like in the genus Pegasus (P. volitans Linneeus). The tail is elongate, the posterior rings flattened and compressed in the genus Parapegasus Dumeéril, type, P. natans Bloch. NO. 1241.

(zapado&os, paradox.) Family 3. SYNGNATHID. THE PIPE FISHES. Body elongate, usually slender, covered with bony plates which are firmly connected, forming a bony carapace. Head slender, the snout long, tube-like, bearing the short toothless jaws at theend. Gill open- ings reduced to a small aperture behind the upper part of the opercle. Tail long, prehensile or not, usually provided with a small caudal fin. Male fishes with an egg pouch, usually placed on the under side of the tail, sometimes on the abdomen, commonly formed of two folds of skin which meet on the median line. The eggs are received into this pouch and retained until sometime after hatching, when the pouch opens, permitting the young to escape. Dorsal fin single, nearly median, of soft rays only; pectorals small, or wanting; ventrals, none; anal fin minute, usually present. Small fishes, found in all warm seas, some- times entering fresh waters. Syngnathine: a. Tail not prehensile, usually with a caudal fin; axis of head usually in line with axis of body. b. Humeral bones united. c. Pectoral fins present; caudal present. d. Male with the egg pouch under the tail, formed by lateral membranes which become connected along the middle, forming a closed pouch. e. Dorsal fin inserted over or just before the vent. jf.

The name Siphostoma was given to S. pelagicus and its relatives, the Syngnathus of late writers; that of Tiphle to S. typhle, the Siphonostoma of late writers; while Syngnathus was retained for S. aequoreus and its relatives, the group now usually called Nerophis, the type of Nerophis being Syngnathus ophidion Linnaeus. This arrangement has been previously adopted by us, but it is open to two very serious objections besides the fact that it is contrary to the general usage, which makes acus the type of Syngnathus, in accord- ance with Swainson’s arrangement. These objections are (1) that Artedi, from whom Linnaeus accepted the genus Syngnathus, did not know of the existence of Syngnathus xquoreus, and (2) the statement of Linnaeus (which we have been unable to verify), that the type of each of his genera is the ‘‘ best known European or officinal species.” Syngnathus acus would meet this requirement, but not Syngna- thus equoreus, which had not then been found in Europe. no.1241.

Color light-brown, with gray streaks and blotches; white lines radiating from eye and white streaks on snout and side of neck; the pale markings on side of body in our specimen suggest coralline patches; dorsal with a dark cross-shade. 16 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXIV. Kast facies: widely disueibure d, north to Riu Kiu Islands. This description is from a specimen 115 millimeters long, from Ishigaki, Yaeyama Island, Riukiu. We identify this specimen with //. huda with some doubt, and we are not sure of the synonymy of the species, even if the identification be accepted. According to Dr. Day, the number of rings in //. huda (guttulatus) is 11 + 33. The relations of this species to the other large-sized and long-nosed sea horses are still obscure.

Depth of trunk 1% times snout. Coronet high, almost as high as the length of snout. It is laterally compressed up to its middle, ends anteriorly in an acute triangular spine with a filament, also terminates posteriorly in an acute spine, without filament. From the middle up it is longitudinally compressed, giving rise to a laterally expanded, fan-like process, with five spines, pointing upward; the one next to each end with a filament. Supraorbital spines very prominent, with filaments and a distinct minor spine inthe immediate front of each, all pointing anteriorly, large ones slightly outward as well; a well-marked spine on median line before eyes. Tubercles on body rather high, those in first, fourth, seventh, and tenth body rings, and second, fourth, sixth, eighth, tenth, and thirteenth tail rings enlarged and with filaments.

Head mottled with dark gray on greenish ground, interspersed with light cross bars and streaks. Middle line of belly black. Fins dusky, unmarked except the dorsal, which has a dark band longi- tudinally. Egg pouch occupies seven rings, greenish and covered with prickle-like processes. This species is known from one small specimen, an adult male 38 millimeters long, type No. 47930 U. S. National Museum, dredged by the U. S. Fish Commission steamer Albatross in Totomi Bay, off Hamamatsu, in the province of Totomi, Japan. The species is allied to 1. mohnikei, but differs in the form of coronet, the number of fin rays, and slimness of body, and also its size, which is much smaller than the smallest specimen of mohniker.

LIST OF THE MYRIAPOD FAMILY LITHOBIIDAD OF SALT LAKE COUNTY, UTAH, WITH DESCRIPTIONS OF FIVE NEW SPECIES. By Rateu V. CHAMBERLIN, Of the Latter-day Saints’ College, Salt Lake City. The five new species of Lithobius described in this paper are based upon material in collections made by the author from June to October, 1900, and in February, March, and April, 1901. Types of these new species have been deposited in the United States National Museum. Inasmuch as nothing upon the Myriapoda of Utah has been heretofore published, some notes are also given on the other species of the Litho- biide found within the limits of Salt Lake County.

By Davip Starr JorpDAN and JOHN OTTERBEIN SNYDER, Of the Leland Stanford Junior University. In the present paper is given a descriptive catalogue of the species of gobies found in the waters of Japan. it is based primarily on the large collection made by the authors in Japan in the summer of 1900, under the auspices of the Hopkins Biological Laboratory of Stanford University. Numerous additional specimens have been presented by the Imperial University of Tokyo through Dr. Kakichi Mitsukuri, and by the Imperial Museum of Japan through Dr. Chiyomatsu Ishi- kawa. The gobies collected by the U.S. Fish Commission steamer Albatross in 1900, the collections in the United States National Museum, and the collections of Professor Keinosuke Otaki in 1895 and 1896 have also been considered, as well as the collections made by Mr. Pierre Louis Jouy in 1885. A series of typical specimens are in the U.S. National Museum and in the Imperial University of Tokyo. Duplicates have been presented to several other institutions. 5 The accompanying drawings are the work of Mrs. Chloe Lesley Starks, artist of the Hopkins laboratory, and of Mr. A. H. Baldwin. MEASUREMENTS. The measurements given in the tables were made by means of dividers and a proportional scale. In some cases they will be of great value as an aid in discriminating between closely related species. It is believed also that they will show, in an approximately definite way, some of the variations of certain characters useful in the determination of relationships. They are expressed in hundredths of the length of the body, which is measured from the tip of the snout to the end of the last vertebra. The depth of the body is measured at its deepest part; depth of caudal peduncle at its narrowest place; length of caudal peduncle from base of last anal ray to end of last vertebra; length of head from tip of snout to posterior edge of opercle; length of snout from its tip to anterior margin of orbit; width of interorbital space measured on PROCEEDINGS U. S. NATIONAL Museum, VoL. XXIV—No. 1244. Proc. N. M. vol. xxiv—01——3 34 PROCEEDINGS OF THE NATIONAL MUSEUM. | VOL. XXIV. the skull, the dividers compressed tightly between the eyes; diameter of orbit, longitudinally; length of caudal fin from end of last vertebra to tip of longest rays. Only fully developed fin rays are counted; the rudimentary rays of dorsal and anal when closely adnate to the first branched ray, are counted with it as one ray; when the soft dorsal contains a spine, it is enumerated as a ray. When last ray of dorsal or anal is double it is counted as one. Scales in the lateral series are counted to base of caudal fin; transverse series from insertion of ventrals or anal, whichever is nearer middle of body, upward and forward; above or below lateral line as indicated in the description. Family GOBUD. THE GOBIES. Body oblong or elongate, naked or covered with ctenoid or cycloid scales. Dentition various, the teeth generally small but sometimes developed into great canines; premaxillaries protractile; suborbital without bony stay. Skin of head continuous with covering of eyes. Eyes usually moderate, sometimes concealed. Opercle unarmed; pre- opercle unarmed, or with a short spine; pseudobranchiz present or absent. Gills 4, a sht behind the fourth; gill membranes more or less united to the isthmus, the gill openings thus restricted to the sides. No lateral line. Dorsal fins separate or connected, the spinous dorsal short, of 2 to 8 flexible spines, or sometimes wanting; anal usually with a single weak spine, the fin similar to soft dorsal; ventral fins close together, separate or united, each composed of a short spine and 3 or 4 soft rays, the inner rays usually longest; the ventral fins when united form a sucking disk, a cross fold of skin at their base complet- ing the cup; caudal fin convex; anal papilla prominent. No pyloric veca; usually no air bladder. Carnivorous fishes, mostly of small size, living on the bottoms near the shores in warm regions. Some inhabit fresh waters and others live indiscriminately in either fresh or salt water; many of them bury in the mud of estuaries. Few of them are large enough to be of much value as food. The species are for the most part easily recognized, but their arrangement in genera is a matter of extreme difficulty. Until the multitude of Asiatic forms are critically studied, any definition of the Japanese genera must be tentative only. ANALYSIS OF GENERA OF JAPANESE GOBIID®. I.

VOL. XXIV. Soft dorsal and anal with dusky spots arranged in longitudinal rows; caudal with indistinct dark vertical bands; 2 or 3 on the basal half of fin broadest; pectoral with indistinct, dark, vertical bands. Individuals from the same locality show considerable variation in color. Some are lighter, others darker than the one described. The light spots on the chin and throat are often represented by reticula- tions, while in some cases the white predominates, there being scarcely any dark color. Very young specimens have 3 dark bands passing over the back, and a broad band of dark color along the sides. Described from specimens from the Chikugo River, Kurume. This species reaches a length of nearly a foot. It is rather common in estuaries and river mouths from Tokyo southward. Our specimens are from Tokyo Bay, Lake Biwa (Funaki), Chikugo River, at Kurume, and Kawatana, on the Bay of Omura. It is recorded by Giinther from Chikiang in China. (obscurus, dusky.)

Teeth in narrow bands on both jaws; those in outer row of upper jaw considerably enlarged; the outer ones of lower jaw enlarged, though somewhat smaller than the corresponding ones above. The area bearing teeth extends farther back on the lower than on the upper jaw. Gill open- ing not extending far forward, the width of the isthmus contained about 3 times in length of head. Inner edge of shoulder girdle with a narrow ridge, but without papille. Gill-rakers on first arch 2+ 8; short; pointed; far apart. Anterior nostril with a short tube; the posterior with a narrow rim. Lower jaw without barbels. Head naked; the skin loose and somewhat wrinkled, with a number of elevated mucous pores nearly as large as the nostrils; 1 on each side, above and before the eyes; 1 on the posterior part of interorbital space; 2 behind each eye, and a row of 4, the uppermost of which is largest, along the posterior edge of preopercle. Seales large above, very small on belly; ctenoid growing smooth on anterior and on ventral parts. Nape with a naked space, the scales extending forward in 3 pointed areas, the median of which is short and narrow; the lateral areas wider, extending farther forward and bordering upper edge of opercle. Dorsal fins separate, their bases short. Spinous dorsal greatly ele- vated; the spines slender and filamentous at tips; the second longest, its height 3 in length; the third a little longer than the first; the last about a third as long as the second. Soft dorsal high, the posterior ‘ays longest; when depressed, the tip of fin just reaches bases of first caudal rays. Anal not so high as dorsal; the last ray inserted directly below that of dorsal; the fin, when depressed, falling far short of base of caudal. Caudal rounded posteriorly. Pectorals almost reaching a vertical through vent. Ventrals short, free from body posteriorly. Color in alcohol, light brown; the tint not being uniform, but darker near the center of each scale; sides with four or five very indistinct large dark blotches. Fins a little darker than body, upper anterior edge of soft dorsal white; soft dorsal, anal, and caudal bordered with white, especially in the adult. This description is of a male specimen collected at Tsushima by P. L. Jouy. Many other male specimens are like the one described. Others are somewhat lighter in color. There is some variation in the length of the fin rays. Females have a shorter snout and smaller mouth; much lower and shorter fins, with the white borders narrow and indistinct. The females have 2 or 3 rows of small dark brown spots, 1 spot on each scale of upper part of body, and a very narrow lateral band of the same color, more distinct posteriorly, extending along the sides. Specimens collected in Ishikawa Province by Prof. K. Kishinouye are very light in color, with darker spots on the sides; the spots absent 58 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL.

Pectorals AG Peano Ratuced a oes a spot about as large as pupil on upper part of base of the former. This species is probably closely related to C. wirgatulus or to C. _pftaumde. It more closely resembles the former, but may be easily P : ] distinguished from it by its much less oblique mouth and by having larger scales on the nape. In C. wirgatulus the scales of the nape are minute when compared with those of the body, while on the species in hand they are at least one-half as wide as those of the body. The species is at present known from a single specimen 81 milli- meters long, from Wakanoura, Kii, Japan. Type No. 6450, Leland Stanford Junior University Museum.

Type.—No. 6451, Leland Stanford Junior University Museum. Lo- ality, Misaki, Sagami, Japan. Many specimens from Misaki are lighter in color than the type, a highly colored male; on the lighter one the bands and spots are much more distinct. Individuals from Nagasaki have the color pattern in every detail, as described above, although it is much lighter and less distinct. The species is closely related to C. pflaumi.

Here described from a specimen collected near Tokyo by Professor Otaki. The species is of wide distribution, living in rivers, and is but little less abundant than Cfenogobius similis. It is subject to considerable variation in shape of body, length of maxillary, and in color. Some specimens from Lake Biwa have the caudal peduncle narrower than have those from other localities. The length of the maxillary varies con- siderably with the sex, in the females being much shorter than in the males. Some are very light in color, but the pattern as described is 78 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXIV. usually preserved.

A large pore on interorbital space between posterior parts of eyes. Body with small, thin, cycloid scales, which are more or less deeply embedded in the skin. Anteriorly the scales are closely crowded and somewhat irregularly placed; on the breast and belly they are minute and almost hidden beneath the skin. Dorsal fins well separated; height of longest spines about equal to length of snout; posterior spine connected with the back by a large triangular membrane; rays somewhat higher than the spines, the long- est about equal to depth of caudal peduncle; no membrane connecting posterior ray with the back. Anal equal in height to spinous dorsal; when depressed the anal and dorsal extend an equal distance posteri- orly, both falling short of bases of first caudal rays a distance equal to one-half the depth of caudal peduncle. Caudal rounded. Pectoral rounded; its upper edge with a fringe of 14 or 15 thread-like filaments, of which each ray except the uppermost contributes 2. Ventrals short, free from body posteriorly; the membrane connecting the spines fleshy, elevated; its height equal to diameter of eye, its edge concave. Color in spirits dark above, the throat and belly light; head with indistinct dots above, and scarcely discernible bars on cheeks; sides of body with irregularly shaped small white spots, in which a transverse arrangement is suggested. Dorsal, anal, and caudal fins edged with white, the white of caudal forming a distinct band; membranes of fins with indefinite light spots; first dorsal with a large, round, white spot just behind last spine, where the membrane is black; caudal with a large black blotcl at its base, followed by a transverse row of small white spots, 1 on each ray. Pectorals and ventrals without spots except at the base of the former. Length of the type 100 mm. Smaller specimens have the spots on top of head and the bars or spots on cheeks distinct; anterior parts of body with small dark spots; sides with 8 or 9 transverse, light-colored bands with small light blotches between them, in some cases the bands being broken up into elongate blotches. The dark caudal spot and the white terminal band are very distinct. On the smaller specimens a lateral line is suggested by a row of 29 groups of minute papille extending along the middle of the sides. Each group has 5 or 6 papille in 1, or occasionally 2, vertical rows, which are a little less than the width of a scale in length. A mere trace of the lateral line is seen on large specimens. A specimen from Tsushima appears to have no light spots on the sides. The dark spot at base of caudal is scarcely perceptible. Type No. 6484, Leland Stanford Junior University Museum.

PTEROGOBIUS ELAPOIDES (Giinther). Gobius elapoides GbNTHER, Proc. Zool. Soc. London, 1871, p. 665, pl. Lxmt, fig. ID. Locality unknown, supposed to be from Japan. Coll. A. Adams. Pterogobius cdapoides is very closely related to P. daimio. We have been able to find no striking difference between the two except in color. The former is lighter, the ground shades pinkish-brown and the dark cross-bands dark brown instead of deep brownish black, as in the latter. The bands are narrower in 7”. elapovdes, and there is, in addition to those on the body, alike in the two species, a distinct ver- tical band on base of caudal. This band on the caudal serves to dis- tinguish the species at a glance. In life the dark rings of the body are bordered by narrow bands of bright lemon yellow. The dorsal and caudal fins are dull, brick red. The range of the species is evidently farther to the northward than that of Pterogobius daimio, both species living in clear water about rocks in the open sea. In the original description by Dr. Giinther the habitat of this species was doubtfully assigned to the seas of Japan. We obtained many specimens.at Aomori, at Hakodate, from Matsushima Bay, and from Utatsu in Noto. P. L. Jouy collected numerous individuals at Fusan, Korea.

We have been able to find no great differences between the two forms, except in color. 2. dadmio is darker; the dark bands on body are wider than those of ?. eapoides, and there is no vertical band on caudal. These differences, though slight, are definite and constant in a large number of individuals examined by us. ; Our collecting in Japan seems to indicate that P. davmzo is a south- ern form, the Bay of Tokyo being somewhere near its northern limit. P. dapoides isfound farther to the north, or if extending south is not found on the shores washed by the warm southerly currents. Our specimens are from Misaki, and from Wakanoura.

Body with 5 dark, broad, vertical bands; the last on base of caadal; the first at intersection of spinous dorsal; a suggestion of a dark band on nape; color bands of body saddle-like; extending over the back, but not uniting below. Each scale with a conspicuous, narrow, dusky edging. Fins more or less dusky throughout. This species may be distinguished at once from P. elapoides and LP. daimio by its not having a dark band passing through the eye and over the head. The bands of the body are less sharply defined and not edged with paler. It differs in color from P. virgo in having ver- tical bands on the body.

This genus is allied to Cheturichthys, differing in the presence of about 10 barbels on either side, in the smaller, firmer, and rougher scales, the shorter soft dorsal, the free filaments on upper edge of pectoral, and in the truncate caudal fin. The isthmus is somewhat narrow, as in Cheturichthys, and the tongue is truncate. The known species is small and spotted, resembling Ctenogob/us, but with more dorsal spines and rays and with the numerous white barbels along the lower jaw.

Gill-rakers 3+ 12, rather short and blunt. : Head naked, without barbels; anterior nostril with a high tube. Body with large, ctenoid scales; those anterior to dorsal and pectorals and on belly small and smooth; those on breast anterior to ventrals minute, embedded in the skin. Dorsals separate; the spines long and filamentous, those of the females much shorter. Anal inserted below third or fourth dorsal ‘ay, when depressed extending as far posteriorly as the dorsal, neither quite reaching the caudal. Caudal fin rounded. Pectoral without filaments on its upper border. Ventrals of moderate size; free posteriorly. Color dark; head with a few small, faint light spots; body with nar- row, light, lateral bands, which are more distinct posteriorly; dorsals dusky; with subdued darker markings; the first spine or ray of each fin with 4 sharply outlined black dots; soft dorsal and anal narrowly edged with white; interradial membranes of caudal dark; pectoral with a vertical white band near its base, and a dark spot at upper edge of base. The band of pectoral is bright orange in life. In some specimens the snout is broader, the cheek muscles more puffed out, the eye a little smaller, and the maxillary slightly shorter than in others. Those from some localities are a little lighter in color than the one described. They have definite, small, round, white spots on the lower parts of the cheeks; the longitudinal bars on the body are more distinct and the spot at upper part of base of pectoral is more conspicuous. Trienophorichthys squamistrigatus of Hilgendorf is believed to be identical with Sreydium obscurum of Schlegel. The series of speci- mens examined by us agree with the descriptions of both species referred to above, except in the covering of the breast. Hilgendorf’s statement that the breast is naked is probably due to an oversight, as the region anterior to the ventrals is covered with small, deeply embedded scales. The species is represented in our collection by specimens from Nagasaki on the south to Tokyo on the north. The present description is taken from an individual from Enoshima. Our specimens are from Tsuruga, Aomori, Matsushima, Kawa- tana, Kobe, Kurume, Nagasaki, Misaki, Wakanoura, Same, Enoshima, Niigata, Tone River, Ise, and from Ishikawa-ken. The species is very abundant in the river mouths and estuaries throughout the southern islands of Japan. It is called Zorahaze or Tiger goby. (Obscurus, dusky.) no.1244.

Lucas, Acting Curator of Vertebrate Fossils. The name J/ancalla cali forniensis is proposed for a fossil flightless auk, represented by a nearly complete left humerus found in excavat- ing Third street tunnel at Los Angeles, California, in strata considered by Mr. W.H. Dall as belonging to the Upper Miocene or Lower Plio- cene, probably the former. The type is No. 4976 in the catalogue of fossil vertebrates, U. S. National Museum. The genus is character- ized by a short flattened humerus, devoid of the customary sigmoid flexure, by the moving of the articular head of the humerus toward the ulnar border, and by the development of the ridge for the attach- ment of the brachialis inferior muscle. Total length of specimen 68 mm. That the bird was flightless is shown at once by the shortness and flatness of the humerus, and further by the fact that the bone lacks the slightly sigmoid shape characteristic of the humeri of flying birds, being instead slightly concave on the ulnar border. Absence of the power of flight is also shown by the moving of the articular head of the humerus toward the ulnar side, as in birds which fly well the articular face is well toward the radial border. In the penguins this face is as far down on the ulnar border as the lowest point of the inferior crest, and in the flightless Great Auk the articular surface is nearer the ulnar border than in any other member of the auk family save the one under consideration. The inferior crest is stout and well developed, and incloses a large subtrochanteric fossa. This is pierced for an artery, and so is the corresponding fossa of the Great Auk, while no such perforation is present in the specimens of Lomuza, Alca, or Lunda examined. The humerus has a Jarger medullary cavity than has the correspond- ing bone of the Great Auk, and it is interesting to recall that the leg bones of Hesperonis, the most highly specialized of aquatic birds, PROCEEDINGS U. S. NATIONAL Museum, VoL. XXIV—No. 1245. 188 oo 134 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXIV. were also hollow, and probably filled with marrow. In the penguins the leg bones are filled with cancellar tissue. The bird to which this humerus belonged was more highly special- ized, more completely adapted for subaquatic flight, than the Great Auk, although the wings were not so extremely modified as those of the penguins. This is probably due to the fact that the penguins swim solely with their wings, while the auks use both wings and feet. The occurrence of a flightless auk at so low a geological horizon as the Mio- cene is of great interest,as indicating a much earlier origin for the family. From the greater degree of specialization of the wings, it is Figs. 1 AND 2.—SUPERIOR AND INFERIOR VIEWS OF TYPE SPECIMEN OF MANCALLA CALIFORNIENSIS. FIG. 3.—CORRESPONDING PORTION OF LEFT HUMERUS OF LOMVIA TROILE CALIFORNICA, ALL SLIGHTLY ENLARGED. fair to infer that the body of M/ancalla was larger in proportion to the size of the humerus than that of the Great Auk, and that hence the actual bulk of the two was not greatly dissimilar. J/ancalla was cer- tainly larger than any of the murres, although its nearest living rela- tive appears to be the Pacific Murre, Lomwia troile californica. In small birds absence of the power of flight implies freedom from enemies, and as this practically means isolation, it is probable that this flightless auk bred on some islands near the coast. The mollusk fauna associated with the specimen is Miocene in its aspect, and also indicates a cooler climate than that now prevailing in the latitude of Los Angeles, approximately that of Puget Sound. AN ANNOTATED LIST OF MAMMALS COLLECTED IN THE VICINITY OF LA GUAIRA, VENEZUELA. By Wirt Rosrnson, Captain, U. S. Army, and Marcus Warp Lyon, Jr., Aid, Division of Mammals. During the summer of 1900 the authors spent six weeks collecting in the vicinity of La Guaira, Venezuela. The present paper embodies the results of the trip so far as mammals are concerned; the birds, reptiles, and batrachians are treated in the two succeeding articles in this volume. La Guaira, the seaport town of the Venezuelan capital, Caracas, lies along the foot of a range of lofty mountains. This range breaks away from the eastern chain of the Andes in Colombia, bears northeast until it reaches the coast of the Caribbean Sea near Puerto Cabello, thence hugs the shore in an almost due east direction, and finally ends opposite the island of Trinidad. For the greater part of this latter course the slopes fall precipitately into the sea, the waves of the Caribbean break- ing against the foot of the mountains themselves, but in places there is a littoral strip or terrace of no great width. The mountains immediately behind La Guaira reach a height of 8,000 feet, buf from this point fall away gradually as one proceeds to the eastward. There are in the vicinity of La Guaira few or no passes through these mountains. Seven miles to the west there is a rugged gap, high up on the side of which winds the English railroad to Caracas. To the eastward there are no near-by breaks in the chain. Upon these peaks there is constant precipitation, and frequent streams of fine water furrow ravines in their course to the sea. The channels of these streams are well wooded, and would afford good ground for the collector were they not rendered so difficult by their cramped canyon- like character, their precipitous descent, and their bowlder-strewn beds. The few trails that exist avoid these streams and zigzag up the crests of the more practicable slopes. PROCEEDINGS U. S. NATIONAL Museum, VoL. XXIV—No. 1246. 136 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXIV. This northern coast of Venezuela is noted for its heat. The tropi- cal sun beats upon it without mercy, and where water fails the aspect of the country is that of a desert. The littoral plain near La Guaira, where not watered by the acequias, or irrigation trenches, which bring the water from high up on the courses of the mountain streams, is parched and dusty, and given over to Agaves, Cacti of various kinds (Opuntia, Cereus, Melocactus), and to a sage-brush-like plant (Lantana) of characteristic odor. But wherever water can be obtained the plain assumes a most fertile and flourishing character. Such is the condi- tion at Macuto, three miles east of La Guaira. Still farther to the east, some seven miles from La Guaira, a large stream comes down a fair-sized valley. Before debouching upon the plain, its water is all carried off to the right and left by the aceguias, and used to operate sugar mills and afterwards to irrigate wide fields of cane. In what might be called the delta of these two acequias lies the little strageling village of Caraballeda, and a short distance up in the mouth of the valley itself are some dozen scattered huts, the group bearing the name of San Julian. Immediately back of the littoral plain there rises to about 500 feet a first row of red-clay foothills of the same character of vegetation as the plain. Behind these foothills, and springing almost from their tops, rise the mountains proper, and these latter are more or less well wooded, but are too steep and rough to afford collecting ground. On their southern aspect these mountains appear to be wooded only in the folds, while the ridges are covered with coarse grasses. . The western slopes of the San Julian Valley, although precipitous, have been cleared where it was possible for the peons to climb, and have been planted with coffee; but as the coffee plants require shade, fruit trees of several kinds have been set out, so that the hills may still be said to be wooded. About three miles up the valley the virgin forest is encountered. Owing to several causes of uncertainty the trip could not be decided upon until the last minute, and less than a week was available for preparation. As a consequence there were some deficiencies in the outfit, notably in the number of Schuyler rat killers, the trap which ras found to be by far the most useful. Sailing from New York on June 21, the writers reached La Guaira on the morning of July 1. Ten days spent in collecting in the vicinity resulted in but slight success, owing partly to a week’s delay in getting guns through the custom-house, partly to the apparent scarcity of mammalian life, and partly to the prevailing drought and to poor luck at trapping. For- tunately a portion of the outfit was a cane gun, which ‘escaped the notice of the customs officials, and with which a number of bats and small birds were secured. No. 1246. MAMMALS OF VENEZUELA—ROBINSON AND LYON. 137 On July 6 Captain Robinson made a reconnoissance along the rail- road to Caracas in search of better collecting ground, but saw only one place that looked at all promising, a station called Cucuruti, about halfway up the road. He spent a half day here on July 7, but was unable to arrange for food or shelter. On July 11 he made a second reconnoissance, this time to San Julian, and finding that the ground was favorable and that he could secure a vacant hut, he moved there on July 13 and remained until August 10. Mr. Lyon joined him on July 16, but was compelled by illness to return to La Guaira on July 22. He shortly after moved to Macuto, where he collected until August 10, in the meantime making one excursion for bats to a cave near Peia de Mora, on the La Guaira and Caracas Railroad, 9 miles below Caracas and at an elevation of 2,295 feet. The return steamer to New York was taken on August 15. In submitting these notes the writers wish to express their indebted- ness to Mr. Gerrit S. Miller, jr., for much advice on technical points; to Dr. J. A. Allen, of New York City, Mr. Witmer Stone, of Phila- delphia, and Mr. Outram Bangs, of Boston, for the examination of South American material in their possession; and to Mr. Oldfield Thomas, who compared several specimens with types in the British Museum. Owing to his connection with the U. S. National Museum and facili- ties for comparisons and references, the descriptions of new species and the technical parts of this paper are entirely the work of the junior author, while the field notes have been almost exclusively compiled by Captain Robinson. Where specimens are listed by numbers in the following pages it should be observed that those specimens preceded by the letters ‘* W. R.” are in Captain Robinson’s collection,’ while specimens unpreceded by letters belong to the Museum collection. Measurements of speci- mens are in millimeters unless otherwise stated. 1.

Hist., TX, p. 23. 1900. Didelphis karkinophaga Banas, Proc. New Eng. Zool. Club, I, p. 89. Represented by five specimens, an adult female and four young. This was the first mammal trapped, and all were taken in rat killers baited with bananas. They are very tenacious of life, none being killed by: the traps. 1 During the course of printing this paper Captain Robinson has generously pre- sented a large number of his specimens to the U. 8. National Museum, 188 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXIV, The adult and two of the young possess long black hairs scantily overlying the under-fur. One of the young has these black hairs replaced by white, and in another most of the black hairs are so replaced. The tail is eminently prehensile. Measurements of the adult female: Length, 700; tail, 350; hind foot, 50. 2. CALUROMYS PHILANDER (Linnaeus). WOOLLY OPOSSUM. Local name: Comadreja, a misnomer, as the word is Spanish for weasel. 1888.

Caluromys philander ALLEN, Bull. Amer. Mus. Nat. Hist., XIII, p. 189. One adult female and three young collected by Captain Robinson at San Julian. The tail is uniformly brown in color, as in C. trinitatis (Thomas) instead of having the terminal portion white, which is said to be typical of specimens from Guiana. Its skull measures a trifle less than that of the female given by Mr. Thomas in his Catalogue of the Marsupialia. In the following measurements the figures in parentheses are those given by Mr. Thomas. Skull: Basal length, 44 (48); greatest breadth, 28.5 (31); nasals, length, 20 (21.5); maximum breadth, 7 (6.8); minimum breadth, 3.5 (3.3); postorbital processes, tip to tip, 15.5 (16); intertemporal constriction, 9.8 (9.5); palate, length, 25 (28); breadth outside m’, 15 (16.5); inside m*, 10.5 (11.5); length molars 1-8, 7 (8). Dimensions of female collected at San Juliin, August 1: Length, 517; tail, 307; hind foot, 38. One is struck at once by the difference in aspect between this and the common opossum; its rounded head, much more rounded than is usually represented in cuts; its large, mild, yellowish-brown eyes, so different from the beady black eyes of the other species; its woolly fur with no coarse hair, and its very long and slender prehensile tail. The young cling to their mothers’ wool by their tails, mouths, hands, and feet, and the strength of their grasp is remarkable. The pouch of the female is lined with orange-brown hair and. contains six rather prominent mammee. 3. PERAMYS BREVICAUDATUS (Erxleben). SHORT-TAILED PIGMY OPOSSUM. Local name: Ratén Casiragua. 1888. Didelphys brevicaudata Tuomas, Cat. Marsupialia and Monotremata, Brit. Mus., p- 306. Only one specimen of this interesting little animal was secured, a young female trapped at San Julian on August 7. It was taken in a thicket of vines near a stream, in a cyclone trap baited with rolled oats. Its tail is not prehensile. The specimen was identified by Mr. Oldfield Thomas. It measures as follows: Leneth, 144; tail, 55; hind foot, 17. NO. 1246, MAMMALS OF VENEZUELA—ROBINSON AND LYON. 189 4. CABASSOUS LUGUBRIS (Gray). NAKED-TAILED ARMADILLO. Local name: Cachicamo. 1873.

Cabassous hispidus Banas, Proc. New Eng. Zool. Club, I, p. 89. One specimen, a young male, was obtained by Captain Robinson at San Juliin on July 11. Its measurements were: Length, 498; tail, 192; hind foot, 73. . It was kept alive until the following day. When put down near water it waded in and drank freely by rapidly protruding and retract- ing its slender tongue. This was 8 mm. wide at the widest point, and could be extended 60 mm. beyond the tip of the nose. There were fleshy filaments in the nostrils pointing to the front, and prob- ably serving the purpose of the hairs in the nostrils of other animals. Its gait was very awkward; it stepped on the tips of the large claws of its forefeet and turned in its hind feet with the waddle of a musk- rat Its testes were abdominal. Its penis was recurved and turned to the left, so that in urinating a fine stream was ejected backward between its hind legs and to the left of its tail, This is probably a result of its burrowing habits. Its excrements were rounded and very hard, consisting apparently of earthy and gritty matter taken in along with its food. It made no attempt
