MYSCUS CRINITUS) FROM SONORA, MEXICO. BY SETH B. BENSON, Museum of Vertebrate Zoology, University of California. _ Field work in northwestern Sonora in the past four years has brought to light the existence of a great amount of geographic variation in the canyon mice (Peromyscus crinitus) inhabiting that area. The extremes in paleness and darkness in this species occur between populations living only a few miles apart. A high degree of isolation, and great differences in the color of the rocky hills which this species inhabits, seem to be correlated with this geographic variation. Peromyscus crinitus delgadilli, new subspecies. Type.—Adult male, skin and skull, no. 88042 Mus. Vert. Zool.; from 2 miles south of Crater Elegante, Sierra del Pinacate, 34 miles west of Sonoita, Sonora, Mexico; collected March 28, 1938, by Margarito Del- gadillo; original number 4963 Seth B. Benson. Distribution.—Limited to the Pinacate lava field in northwestern Sonora. Diagnosis and comparisons.—A race characterized by dark color, long, unicolored dark tail, and dark hind feet. All of the other known subspecies have white feet and bicolored, or white, tails. Color (capitalized color terms after Ridgway, Color Standards and Color Nomenclature, 1912).—Hair on dorsum with base Dark Plumbeous, narrow subterminal band Cartridge Buff, tip black. Lateral stripe and pectoral spot Light Buff. A faint buffy wash on some belly hairs which otherwise have white tips and Dark Plumbeous bases. Hairs of tail black. Hind feet black to base of toes. Skin of ears and hind feet dark-pigmented. The dark pigment is dominant in the general tone of color. Measurements.—Average and extreme measurements in millimeters of 6 adult and subadult males: Total length, 182 (173-188); tail, 104 (94-115); hind foot, 20 (19-21); ear from notch, 20 (19-21); ear from crown, 17 (16- 17); weight in grams, 12.1 (10.6-14.2); length of head and body, 79 (71- 87). Skull: Greatest length, 23.7 (23.3-24.3); basilar length, 17.5 (17.0- 18.0); zygomatic breadth, 11.3 (11.0-11.7); interorbital constriction, 4.0 (3.8-4.1); nasals, 9.1 (8.9-9.2); shelf of bony palate, 3.3 (3.2-3.4); palatine 1—Proc.

Specimens examined.—Total number, 8, all from the Sierra del Pinacate, Sonora, Mexico, as follows: Crater Elegante, 4; 2 miles south of Crater Elegante, 3; Batamote, Rio Sonoita, 30 miles WSW Sonoita, 1. Remarks.—Seven of the eight specimens resemble each other closely, but one specimen from Crater Elegante is like the members of the population living on the Sierra Hornaday. This specimen may indicate either that isolation is not complete or that the population is not yet homozygous for dark color. Peromyscus crinitus rupicolus, new subspecies. Type.—Adult female, skin and skull, no. 83034 Mus. Vert. Zool.; from Paso MacDougal, east end of Sierra Hornaday, Sonora, Mexico; collected March 25, 1938, by Seth B. Benson; original number 4944. Distribution.—Probably restricted to the Sierra Hornaday. Diagnosis and comparisons.—A dusky, long-tailed race. Differs from P. c. disparilis in darker color, more sharply distinct dark stripe on tail, and duskier ears. Subterminal band on dorsal hairs narrower, Pinkish Buff rather than Light Ochraceous-Buff. Black tipping on hairs more pro- nounced. Much paler than delgadilli. Color.—Hair on dorsum with base Dark Plumbeous, narrow subterminal band Pinkish Buff, tip black. Hair of ventral surface with base Dark Plumbeous and tip white. Feet white. Tail bicolor, black above, white beneath. Skin of ears heavily pigmented. Measurements.—Average and extreme measurements in millimeters of 4 males: Total length, 181 (175-188); tail, 105 (96-112); hind foot, 19; ear from notch, 20 (18-21); ear from crown, 17 (15-18); weight in grams, 11.5 (10.1-11.9); length of head and body, 71 (64-79). Skull: Greatest length, 23.6 (23.3-24.1); basilar length, 17.3 (16.9-17.6); zygomatic breadth, 11.3 (11.0-11.5); interorbital constriction, 3.9 (8.8-4.0); nasals, 9.1 (9.0-9.2); shelf of bony palate, 3.2 (2.9-3.4); palatine slits, 5.2 (4.9-5.3); diastema, 5.7 (5.5-6.0); postpalatal length, 8.3 (8.1-8.4); maxillary toothrow, 3.4 (3.3-3.5). Specimens examined.—Total number, 7, from the type locality. Remarks.—Some specimens of P. c. disparilis from Tule Tank, Yuma County, Arizona, are intermediate in characters between disparilis and rupicolus. There is no indication of intergradation with delgadilli except that one specimen of the latter differs sharply from the rest and resembles rupicolus in color. Possibly this specimen indicates that immigration to the lava bed across the low desert takes place from time to time. Peromyscus crinitus scopulorum, new subspecies. Type.—Adult male, skin and skull, no. 83045 Mus. Vert. Zool.; from Cerro La Cholla, 6 miles west-northwest of Punta Pefiasca, Sonora, Mexico; collected April 3, 1938, by Seth B. Benson; original number 5024. Disiribution.—Restricted to the Cerro La Cholla, northwestern Sonora. Diagnosis and comparisons.—A large, bright-colored, long-tailed race. Differs from P, c, disparilis in duskier color, more sharply bicolored tail, Benson—The Canyon Mouse from Sonora, Mexico. 3 greater size. Color difference on dorsum caused by wider basal band, narrower subterminal band, wider black tip. Skull, nasals, and palatine slits longer. Braincase more rounded, higher, especially in region of inter- parietal. Differs from delgadilli and rupicolus in paler, brighter color, larger size, and in the skull characters listed above. Color.—Hair on dorsum with base Dark Plumbeous, narrow subterminal band Light Ochraceous-Buff, tip black. Lateral stripe Light Ochraceous- Buff. Hair on belly with base Dark Plumbeous, tip white. Tail bicolor, dark above, white beneath. Feet white. Measurements.—Average and extreme measurements of 5 adult and subadult males: Total length, 189 (179-197); tail, 109 (104-115); hind foot, 19 (19-20); ear from notch, 20 (19-21); ear from crown, 17 (15-17); weight in grams, 15.3 (13.8-17.0); length of head and body, 80 (75-82). Skull: Greatest length, 24.2 (23.9-24.5); basilar length, 17.5 (17.2-17.8); zygo- matic breadth, 11.5 (11.3-11.7); interorbital constriction, 4.0 (8.9-4.1); nasals, 9.4 (9.0-9.9); shelf of bony palate, 3.4 (3.2-3.5); palatine slits, 5.3 (5.1-5.5); diastema, 5.8 (5.7-5.9); postpalatal length, 8.3 (8.1-8.5); maxil- lary toothrow, 3.3 (3.2-3.4). Specimens examined.—Total number, 6, all from the type locality. Remarks.—There is confusion regarding the names of the landmarks near the type locality. According to present usage, the name Punta Pefiasca is restricted to the fishing village situated at the base of a lava hill which projects into the sea. Five miles west-northwest there is a granitic headland also projecting into the sea and now known locally as Cerro La Cholla. According to various maps this headland has been named Punta Pefiasca, Punta Pefiascosa, Punta Piedras, and Sea Lion Bluff. For in- stance, on the map (Baja California, Norte; 1 : 1,000,000; Provisional Edition; American Geographical Society of New York, 1924) Cerro La Cholla is labeled Punta Pefiasca. Probably the name Punta Pefiasca was first applied to this headland, and not to the much smaller lava hill, but I follow present usage in restricting the name Punta Pefiasca to the fishing village. The three subspecies named above are to me indistinguishable from P. c. disparilis in proportions and in most skull characters. All may be dis- tinguished from P. c. stephenst by their greater size and longer tails. The differences between disparilis, scopulorum, rupicolus, and delgadilli are chiefly in color. Each one of these subspecies has an extremely restricted range. The area occupied by scopulorwm, for instance, is approximately one square mile. Notwithstanding the small areas of range these popula- tions are clearly distinct from one another. The pale yellow disparilis and the nearly black delgadilli are the extremes in color for this species and yet their ranges are separated only by a few miles. The following circumstances help to explain the existence of these differ- ent colors. In this area this species inhabits only the steepest and rockiest places; these, for the most part, are separated from one another by low- lying, sandy desert where this species ordinarily does not occur; some of the hills are nearly white or light gray, and others are black. There is a definite correlation between the color of the animal and the color of the background in which it lives. eave SCAN Ny Vol. 53, pp. 5-6 February 16, 1940 PROCEEDINGS —_-- Comparisons.—Tantilla canula from Yucatdén is somewhat similar (ac- cording to descriptions), but appears to differ in having the mental in contact with the chinshields, ventrals and subcaudals somewhat less numerous (105-110 ventrals, 37-41 subcaudals), and in having pigment on the belly as well as on the back. Tantilla breve from British Honduras differs in having the eye less than half the length of the snout, internasals more than half as long as prefrontals, frontals scarcely longer than broad, and perhaps in coloration. One of the most distinctive characters of the present species may very possibly be the large number of maxillary teeth. Remarks.—The type was found at night, moving about in leaves on the ground in heavy forest. The species is named for Mr. Linton P. Satterthwaite, whose kindness enabled us to collect for a considerable length of time at the archeological station at Piedras Negras. Trimeresurus garciai, new species. In the excellent herpetological collection from the states of Veracruz and Puebla that has been assembled recently by Mr. Dyfrig McH. Forbes and Sr. Gabino Garefa of Potrero Viejo, Veracruz, perhaps no species comes as a greater surprise than this. Three specimens, one of which has very kindly been presented to me and another to Edward H. Taylor, were secured by one of these collectors near Cacaloapam, Puebla, on a semi-arid plain. The exact spot is near kilometer 226. All were found during the process of excavating mounds of Mammillaria cacti in search of Eleutherodactylus cactorum.

Description of holotype-—Head nearly three times as broad as neck; snout rounded, seen from above, slightly projecting in profile; rostral about twice as broad as high, projecting very slightly above edge of upper head scales; four convex internasals bordering rostral, the two median much smaller than the one on either side; nasal divided, the anterior section about twice as large as posterior, in contact with first supralabial; three scales forming inner edge of pit; two rows of small scales between pit and labials; one or two scales between pit and nasal; three rows between pit and eye; three or four rows between eye and labial; four canthals; median supra- ocular produced vertically as a broad “horn” three mm. high, 2.2 mm. long, and about a millimeter wide; horn with a deep vertical groove on inner surface and two or three shallow grooves on outer surface, radiating from base; scale preceding this somewhat larger than scales in frontal region, its posterior edge produced slightly upward against anterior edge of the horn; eleven rows of scales between horns; scales on sides of head not keeled, those on lower temporal region quite smooth and flat, others convex; lower temporal scales somewhat larger than or nearly the same size as posterior supralabial; dorsal head scales small, those posterior to frontal region heavily keeled and with small ridges radiating from the median keel of each scale; anterior dorsal head scales not keeled their full length, but with a prominent posterior knob; supralabials and infralabials eleven. 64 Proceedings of the Biological Society of Washington. Mental with a labial border somewhat greater than that of rostral; scales of first pair of infralabials in contact behind mental; one pair of chinshields, not much longer than broad; three labials in contact with chinshield; five pairs of small scales following chinshield, then one small median scale; all ventral scales smooth, flat. Dorsals in 23-21-17 rows, those of outer row not keeled, those of second row very weakly keeled, others rather strongly keeled; ventrals 146; anal entire; subcaudals 40, all entire. Color.—General ground color light tan, very slightly suffused with pink, rather heavily stippled with dark brown; a series of diagonal brown blotches, sometimes dark-edged anteriorly, down middle of back; blotches extending over six to eight rows of scales transversely, about three longitudinally; they are connected diagonally by narrower extensions of the same color about one and one-half to two scales wide, so that the general effect is a _ zigzag line down the back; small dark blotches, arranged in two rows, very dimly evident on the sides; a light postocular stripe, one and one-half to two scales broad, not sharply defined, extends from eye through temporal region onto anterior part of neck, there disappearing; below this a somewhat narrower dark brown stripe which involves the upper half of the posterior supraocular and disappears on side of neck; supralabials light except anter- ior scales; a dim, somewhat star-shaped light mark on occiput; upper surface of head otherwise dark brown. Infralabials, except anterior ones, pinkish cream, stippled with dark brown, and with a few well-defined small, very dark spots irregularly arranged; another dark spot, larger but not so well defined, on postero- lateral gular region. Mental and anterior infralabials gray, heavily pig- mented; other ventral head shields with scattered pigment. Belly and ventral surface of tail heavily pigmented, more posteriorly than anteriorly, with scattered light areas. Dorsal surface of tail nearly uniform dark brown, nearly black, the color extending onto ends of subcaudals; a brilliant white line extending from base of tail along second scale row to tip of tail, descending posteriorly until it lies upon the lateral edges of the subcaudals; a narrow, transverse white band across base of tail near anus. Variation.—In ventral and caudal counts the series is amazingly uniform. All have 146 ventrals, and the two with complete tails have 40 caudals (both males). In the two paratypes (U. S. National Museum and E.H.T.—H.MSS. respectively) the scale rows are 25-21-17, 23-21-17; supralabials 12-14, 10-11; infralabials 11-11, 11-12; scales between ‘‘horns” 13, 10; total length 407 mm., 449 mm.; tail 55 mm., 51 mm. The dorsal pattern of the female is obscure. Comparisons.—The species is somewhat similar to Trimeresurus undu- latus, but differs markedly in having entire instead of divided subcaudals, as well as in other less obvious characters. There seems to be no other described species similar to it. Vol. 53, pp. 65-66 June 28, 1940 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON TWO NEW GEOPHILOID CHILOPODS FROM MEXICO AND TEXAS. By Raueu V. CHAMBERLIN. Of the two new chilopods herein described the first is a member of the Schendylidae and is represented by two specimens sent to me for identification by Mr. E. J. Koestner of the University of Illinois, by whom they were taken at an elevation of 12,500 feet on Cerro Potosi, Nuevo Leon, Mexico. The type of the second form represents a new species in the genus Sogona, family Sogonidae. It was taken in Kerr Co., Texas, by Dorothea and Stanley Mulaik in December, 1939. Simoporus koestneri, new species. Cephalic plate longer than broad, narrowed toward both ends, the caudal margin truncate. No frontal suture showing. Prebasal plate clearly exposed. Antennae filiform. Claws of prehensors when closed even with or slightly short of the anterior margin of the head; none of the joints armed within. Anterior margin of coxosternum unarmed. No chitinous lines present. Anterior sternites with posterior margin angularly produced into an excavation of the succeeding plate. Sternites not sulcate. Ventral pores in an undivided circular area, this relatively small. Spiracles small, circular, the first but slightly larger than the second. First legs but little smaller than the second. Anal legs in the male much thicker and longer than the penult, the third joint thickest, from which the legs are attenuated gradually to the end; claw distinct, slender. Labrum widely and evenly arched over middle portion, this concave middle portion bearing typically 15 stout teeth; widely separated pectina- tions on each side, the outermost of these close to end of labrum. The inner branch of first maxillae presenting two setae, as against three shown for Nyctunguis dampfi, and the outer branch or palpus four setae as against three. Otherwise the first maxillae very similar to those of that species. The clypeus free from setae posteriorly; at anterior end a pair of setae 14—Proc. Biou. Soc. Wasn., Vou. 53, 1940. (65) VUL -1 1940 66 Proceedings of the Biological Society of Washington. and behind this several setae irregularly arranged at three levels, with setae on each side tending to form a single series. Last ventral plate proportionately broad, trapeziform. Each anal coxa with a single large pore which is nearly covered by the border of the sternite. Genital appendages large, the apical article conical, setose, extending a little beyond caudal end of somite. Pairs of legs in male, 41. Length, 18 mm. Locality.—Mexico: Nuevo Leon, Cerro Potosi, at an elevation of 12,500 ft. Two specimens collected by E. J. Koestner in soil in scrub pine growth. One specimen lacks the posterior end. This species presents many resemblances to Nyctunguis dampfi (Verhoeft) the types of which were also taken in Mexico in the high mountains, having been taken by Prof. Dampf at the Desierto de los Leones at an elevation of 9,000 feet. Sogona kerrana, new species. Antennae moderate, attenuated from base where they are nearly contigu- ous. No frontal suture. Prebasal plate a little exposed at the middle. Claws of prehensors when closed not quite reaching the anterior margin of the head. Joints of prehensors not armed within. Chitinous lines complete. Ventral pores of anterior sternites few, in the usual narrow transverse band behind middle of sternite. Spiracles all circular, the first but little larger than the second. Last ventral plate wide. Pores of anal coxae large, two on each side, mostly exposed. Anal legs in the male moderately inflated, of nearly uniform thickness to the second tarsal joint which is abruptly thinner. Tarsus terminating in a membranous point, without a true claw. Pairs of legs in male holotype, 57. Length, about 25 mm. Localities.—Texas: Kerr Co., Turtle Creek, one male taken in December, 1939; Raven Ranch, one younger male, also taken in December, by D. and S. Mulaik. Much resembling Garrina ochra in the form of the anal legs excepting in the lack of terminal claws. It is a much larger form that Sogona minima from which it differs also in lacking the deep median longitudinal furrow on the sternites characteristic of minima, etc. fs Ve —_ Vol. 53, pp. 67-70 June 28, 1940 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON ON THE MOLLUSCAN GENUS TRIMUSCULUS SCHMIDT 1818, WITH NOTES ON SOME MEDITERRANEAN AND WEST AFRICAN SIPHONARIAS. BY HARALD A. REHDER. Trimusculus was proposed as a new generic name for several Patellas on page 218 of the rare work by Fredrich Christian Schmidt, entitled, in brief, ‘‘ Versuch uber die beste Einrichtung . . . der Conchylien-Sammlungen .. .,”’ Gotha, 1818. The diagnosis given here is adequate enough so that we know that he was separating the air-breathing limpet-like mollusks that we know as Gadinia and Siphonaria, from the gill-bearing marine forms. Moreover, he lists as belonging to his new group thirteen species of Patella, namely, Patella mammillaris Linné, melanoleuca a, melanoleuca pg, leucopleura a, leucopleura g, leucopleura 4, striatula of Gmelin, and castanea, filaris, caliz, serrata, strigosa, strigosissima of Schroter. The Patella mammillaris Linné is, according to Hanley, the Mediter- tanean Gadinia garnotiit Payr. Patella melanoleuca Gmelin is the West African Siphonaria, that has been called lineolata Orbigny, although this name must be restricted to the Caribbean species. Patella melanoleuca B is probably also a Siphonaria, judging from Schrdéter’s brief description to which Gmelin refers. Patella striatula Gmelin is likewise a Siphonaria. Patella leucopleura Gmelin is a West Indian Acmaea, while leucopleura B and 6 are more or less indeterminable, the variety 6 being possibly a Siphonaria. I have been unable to find a description of the species credited here to Schréter. Since the position of this genus, to which Iredale has recently called attention (British Museum Great Barrier Reef Exped. 1928-29, Scientific Reports, vol. 5, no 6, Mollusca, pt. 1, 1939, p. 274) must be fixed, I designate as genotype the species Patella mammillaris Linné, which will bring about the substitution of Trimusculus Schmidt for Gadinia Gray; the designation 15—Proc. Brox. Soc. Wasx., Vou. 53, 1940. (67) JUL -1 190 68 Proceedings of the Biological Society of Washington. of any of the other recognizable species would cause the upsetting of the more widely used name Sizphonaria. Herrmannsen synonymized the genus with Szphonaria, since he dated the name from 1832, its appearance in Méller’s description of the collection of Schmidt at Gota. Here (see reference below), Moller gives a brief but sufficient description, but mentions no species. Marschall, in 1873, lists Trimusculus with the correct citation, but von Martens, who worked on the molluscan names in this work, apparently did not accept the genus, as he also places it under Siphonaria.

Genotype (here designated): Trimusculus mammillaris Linné (Patella mammillaris Linné). Linné, after his brief description of Patella mammillaris, which he says is found in the Mediterranean Sea, cites figures in Lister and Klein as representing his species. Klein’s figure, which is a copy of that of Lister, is cited also for the following species, Patella pectinata, which likewise is said to come from the Mediterranean. Thus we have two species illustrated by the same figure, which is that of a West African Szphonaria, the Mouret of Adanson. But not only does the description of Patella pectinata fit this West African species better than does P. mammillaris, but the specimen marked for this species in the Linnean cabinet is, according to Hanley, the Mouret of Adanson. Hanley’s indifferent figure of this Linnean specimen represents the western Mediterranean form long called Siphonaria algesirae R. & G., and similar enough to the West African form to be confused with it. The latter shell, from Liberia, Cape Palmas and southward, is more finely ribbed, and must bear the name Siphonaria grisea (Gmelin), while the more coarsely ribbed form, resulting in the internal brown lines being heavier and more widely spaced, from the western Mediterranean and the Cape Verde Islands, will be called Stphonaria pectinata (Linné). In regard to Patella mammillaris we therefore must disregard the cited figure which represents another Linnean species, and follow Hanley, who fixes the name on a specimen in the Linnean collection of the Mediterranean, Gadinia garnotit Payraudeau, and the description, brief though it be, fits this species better than it does the darker, stouter Szphonaria. Rehder—The Molluscan Genus Trimusculus Schmidt. 69 Weinkauff! maintains that Linné’s description and Hanley’s figure do not agree with Payraudeau’s description in that the latter says his species is longitudinally and transversely striated, whereas Linné does not mention any transverse sculpture, and Hanley’s figure shows only distant growth lines. But Payraudeau’s figures likewise show only three to four spaced growth lines, which apparently represent his transverse sculpture, and an examination of numerous specimens in the Jeffreys collection shows the only transverse sculpture is that of the very variable growth lines. In some specimens the growth lines only inconspicuously affect the radial rib; in others, the shell is strongly marked by interruptions in the growth, and the radial riblets may often be conspicuously nodulose. 1 Die Conchylien des Mittelmeeres, vol. 2, 1868, pp. 175-176. es en ~ ‘ \ . ; \ i Hi RIVES Wh Haare TH r Bel BN eA a iy hie! uy b Vol. 53, pp. 71-74 June 28, 1940 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON a a ean oe aa TWO NEW SPECIES OF HELIOPSIS (ASTERACEAE) FROM SOUTH AMERICA.

Gymnolomia silvatica Klatt is represented in the Gray Herbarium by a sketch of the type (Carl Hoffmann 153, Costa Rica, in silva montis Irazu) in the Berlin Herbarium, accompanied by a pocket containing flowers, pales, and achenes. Examination of this material shows that Klatt’s species is identical with the common and widespread tropical American Heliopsis buphthalmoides (Jacq.) Dunal. Klatt described the leaves as ovate-lanceolate, 3 inches long, 9 lines wide, but the leaf blades are repre- sented in his careful sketch as ovate, 7-8.5 cm. long, 3-3.8 cm. wide. Klatt’s species was referred to Heliopsis by Robinson and Greenman! in their revision of Gymnolomia, but has not previously been synonymized specifically. 1 Proc, Boston Soc. Nat.

It differs from saphes in having a double claw on the anal legs. Lithobius apheles, new species. Dorsum, antennae and last legs brown, the other legs a lighter brown. Antennae moderately long; articles 35. Ocelli 1+4, 4, 4, 3. Prosternal teeth 3+3; median sinus narrowly V-shaped. Posterior angles of 9th, 11th and 13th dorsal plates produced. Ventral spines of first legs, 0,0, 1, 2,1. Ventral spines of penult legs, 0, 1, 3, 3,2; dorsal, 1,0,3,1,1; claws 3. Ventral spines of anal legs, 0, 1, 3, 3, 1; dorsal, 1, 0, 3, 1, 0; claws 2. Last three pairs of coxae dorsally armed, last two pairs laterally armed. Coxal pores small, circular, 4, 5, 5, 5. Posterior legs of male not specially modified. Length, about 11 mm. Locality.—North Carolina: Linville. One male taken Oct. 14, 1939. Differing from other species of the eastern part of the United States in having the anal legs with two claws. The Californian L. chumasanus has two claws on the anal legs but is a much larger form. AW t ( eee sta iw, i 0673 Vol. 53, pp. 79-80 June 28, 1940 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON THREE NEW FORMS OF BIRDS FROM SOUTH ANNAM. BY J. H. RILBY.! Further study of the fine collection ‘of birds made in the neighborhood of Dalat, South Annam, by Dr. Joseph F. Rock has convinced me that the following three forms require separa- tion, and I am accordingly describing them herewith. I am indebted to the authorities of the American Museum of Natural History through Dr. Ernst Mayr for the loan of a series of Arachnothera magna aurata. Oriolus chinensis invisus, subsp. nov. Type.—Male, U. 8. National Museum, No. 359268, Dran, 3000 feet, South Annam, July, 1939. Similar to Oriolus chinensis tenuirostris from the Yunnan Mountains, but considerably smaller; the inner secondaries with larger yellow tips. Wing, 142; tail, 79; culmen, 30.5. Remarks.—This form is founded upon four males and three females from South Annam which have been compared with five males and five females from the mountains of Yunnan. The four males from South Annam measure: wing, 142-150 (147.2); tail, 75-80.5 (78.5); culmen, 29.5- 30.5 (30). Five males from Yunnan: wing, 151-159 (154.8); tail, 84-89 (85.9); culmen, 31.5-32.5 (32.3). Evidently this form was thought to be only a winter visitor to South Annam from Burma and Yunnan, but Rock’s series proves beyond a doubt that it is a breeding bird and probably resident. A pair from Kloss’ collection from the Langbian Region are in the U. S. National Museum. The male collected March 30, and the female May 9; both are in worn breeding plumage as if they had already bred. This would seem to indicate that they breed early. Franklinia rufescens dalatensis, subsp. nov. Type.—Male, U. S. National Museum, no. 359217, Fimnon, 3000 feet, South Annam, August, 1935. 1 Published with the permission of the Secretary of the Smithsonian Institution. 18—Proc. Biot, Soc. Wasn., Vou. 53, 1940. (79) JUL -1 WR yn a 80 Proceedings of the Biological Society of Washington. Similar to Frainlinia rufescens rufescens of northern and eastern Siam, but pileum darker, the supra-loral streak very faint or absent. Wing, 42.5; tail, 41; culmen, 12.5. Remarks.—The above race is founded upon three adult males, one adult female, and one immature without sex from South Annam in the neighbor- hood of Dalat, which has been compared with a good series from northern and eastern Siam. All the specimens examined from Siam in good plumage have a prominent supra-loral white line, in a few cases extending over the eye. In the series from South Annam it is very faint or absent. There does not seem to be any difference in size between the two forms. Arachnothera magna remota, subsp. nov. Type.-—Male adult, U. S. National Museum, No. 359346, Langbian Peaks, 7020 feet, South Annam, June, 1939. Similar to Arachnothera magna magna, but upperparts a more greenish yellow (near pyrite yellow); the black centers to the feathers of the head and back smaller and less conspicuous; bend of wing and under-tail coverts a deeper yellow; lowerparts averaging more yellowish. Also similar to Arachnothera magna aurata, but the lowerparts lighter yellow and the black streaking heavier; bend of wing and under tail-coverts deeper yellow, and the upperparts a more greenish yellow. Wing, 93; tail, 51; culmen, 43.5. Remarks.—The present form is founded upon eleven specimens from the Langbian Peaks region of South Annam. These have been compared with thirteen specimens from northern Siam, one specimen from Nepal, and one from India of Arachnothera magna magna; and seven specimens from Tenasserim and Pegu, Burma, of Arachnothera magna aurata. The Lang- bian form resembles the form from northern Siam more than it does Arachnothera magna aurata. There does not appear to be much difference in size between the three forms. Vol. 53, pp. 81-90 June 28, 1940 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON TEN NEW WHITE-TAILED DEER FROM NORTH AND MIDDLE AMERICA. BY E. A. GOLDMAN anp REMINGTON KELLOGG. A revision of the white-tailed deer of North and Middle America is being completed by the writers. Pending the issu- ance of the more comprehensive account, embracing all of these deer, it seems desirable to publish the following brief descrip- tions of hitherto unrecognized geographic races of Odocoileus virginianus that have come to our attention. In the course of the work, specimens, the examination of which was almost indispensable, have been borrowed from various institutions and from individuals. For this assistance and other courtesies grateful acknowledgment will more specifically be made later. Special appreciation seems, however, deserving of expression to Ted Dealey, and to his son, Joseph MacDonald Dealey, of Dallas, Texas, for their keen interest and for the generous donation of specimens that have enabled us to segregate and describe a well-marked new geographic race from the high mountains of northern Coahuila. The names of colors in quotation marks are from Ridgway’s Color Standards and Nomenclature, 1912. Odocoileus virginianus carminis, subsp. nov. Type locality.—Botellas Cafion, Sierra del Carmen, northern Coahuila, Mexico (altitude 6,500 feet). Type specimen.—Male adult, skin and skull; no. 265224, U. S. National Museum (Biological Survey collection); collected October 27, 1939, by Joseph MacDonald Dealey, X catalog no. 29148. General characters.—A medium sized, drab-colored subspecies, without conspicuously blackish upper side of tail; antlers moderately spreading, with short tines. Approaching Odocoileus virginianus texanus of Texas in color, but smaller; antlers with shorter tines. 19—Proc, Biot. Soc. Wasu., Vou. 53, 1940, (81) JUL -1 1940 82 Proceedings of the Biological Society of Washington. Color.—Type (winter pelage): Upper parts in general a mixture of brownish black and “‘drab-gray,” the banded hairs producing a grizzled effect; top of head and face similar to back, but more finely grizzled, becom- ing clearer gray on sides of muzzle as far forward as the usual black spots near nostrils; outer and anterior surfaces of limbs to hoofs a mixture of “pinkish buff”? and dark brown, the buff predominating; posterior surface of fore limbs to hoofs grayish white; under side of neck and sides of thorax near “drab-gray”’; chin, fore part of throat, median abdominal and in- guinal areas, and inner surfaces of thighs white; tarsal gland tufts “pale pinkish buff,” ears grayish, mixed with a dark shade of brown, tail above “cinnamon buff” along median portion of basal half, becoming brownish black toward tip, the tip and broad lateral fringes white; under side of tail white. Skuwl.—The skull differs markedly from that of Odocoileus virginianus tecanus in smaller general size, including antlers with distinctly shorter tines. Compared with that of Odocoileus virginianus couesi the skull tends to be narrower and more elongated, with more slender rostrum. Measurements.—(Type and an adult female topotype, respectively): Total length, 1512, 1386 mm.; tail, 214, 182; hind foot, 403, 365.

Remarks.—The deer of the Sierra del Carmen, Coahuila, along with those of the Chisos Mountains across the Rio Grande in Texas, here segregated as Odocoileus virginianus carminis, differ distinctly from Odocoileus virgini- anus texanus of the adjoining plains region. That complete intergradation of the two must occur along the basal slopes of the mountains seems, however, 2 safe assumption. Odocoileus virginianus dacotensis, subsp. nov. Type locality.—White Earth River, Mountrail County, North Dakota. Type specimen.—Adult male, skull without antlers, no skin; no. ?$43, U. 8. National Museum; collected by F. V.

It also exhibits a departure from the richer tawny coloration of Odocoileus virginianus thomasi, with which it intergrades on the south. f iy NN, i ih ey * o; oy bes Ninkos nergy es Ecce dh Fete Hy Ob 23 Vol. 53, pp. 91-94 June 28, 1940 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON GENERAL NOTES SKULL OF FOSSIL PORPOISE, Delphinodon dividum, FROM BANKS OF POTOMAC RIVER, AT WAKEFIELD, VIRGINIA. On August 17, 1939, while in the company of Mr. John H. Dante, Mr. Robert Fuerst discovered a porpoise skull protruding from the Miocene sediments of the west bank of the Potomac River a little south of Colonial Beach, Virginia. The skull, which was badly damaged on removal, was brought to the Department of Geology and Geography at The Catholic University of America where it was restored and identified by the writer. It proved to be the remains of a fossil porpoise, Delphinodon dividum, common in the Calvert Miocene of the Chesapeake Region. The remains were exposed on the face of a ten foot cliff, about a foot above the bottom of the river. The men who removed the skull informed me that, under the best conditions, only about two inches of the posterior portion of the skull was above water. To complicate matters toward the end of the work of removal, the water had risen about a foot. In addition to this, the exposure was about fifty feet from the nearest sandy beach in a rather inaccessible location approximately a mile north of Wakefield Mansion. Under these adverse conditions it was not possible to remove the skull with the care that ordinarily could be exercised. The matrix in which the skull was embedded contained much fossil bone and consisted of a fine marine sand with very litle admixed mud. The position of the skull with respect to the strata indicated that it had come to rest at the time of burial with the rostrum inclined downwards at a con- siderable angle. From this it would appear that, after dismemberment from the rest of the body, it had been lodged in a pocket not far beyond the shore limits. The writer, in the summer of 1938, found a considerable quantity of dismembered cetacean remains in this area together with remnants of a partially ossified vertebra of the Miocene shark, Carcharodon megalodon ? which, so far as he is informed, has only been reported otherwise from Zone 12 of the Chesapeake Miocene series. The similarity of the vertebrate fauna from these two areas would make it appear that the strata in question were approximately of uppermost Calvert age. The skull, as restored, is 150 mm. wide at the orbits; 190 mm. wide at the zygomatic processes of the squamosals; and has an overall height of 100 20—Proc. Biou. Soc. Wasu., Vor. 53, 1940.

The dimensions and general appearance of the skull here described resemble so closely those of Delphinodon dividum at the National Museum! and another specimen of this species procured by the writer? from Zone 12 of the Miocene series of the Calvert Cliffs, near Parker Creek, Maryland, that there can be little doubt as to the identification. ArtTHUR R. Barwick, Department of Geology & Geography, The Catholic University of America, Washington, D. C. THE CORRECT NAME OF THE FLORIDA HYDATINA. This beautiful mollusk has for a long time been sailing under a relative’s name, namely Hydatina physis. This is probably largely due to the fact that the animals of members of this genus rarely come into the hands of the taxonomist who deals chiefly with their shells. We have recently had a beautiful series of specimens of the Florida Hydatina brought to our Institution by Mr. John H. Irons, gathered at Lake Worth, Florida, which show at a glance that the animal has an entirely different color scheme from that pictured for H. physts. Our mollusk, instead of being variously ornately attired, has a unicolor brown tint which varies from a burned umber edge at the edge of the mantle to light brownish drab on the major portion of the upper surface. The tip of the tentacles agrees with the edging of the mantle, while the base agrees with the major portion of the body. The foot is light brownish drab. The shell itself is marked by pale and light spiral zones, usually brown ones alternating with bluish black. A search of the literature reveals that in 1786 Solander (Humphrey) used the name Bulla vestcaria in the catalogue of the Portland Museum, page 136, for the West Indian shell, basing this upon Albertus Seba’s “‘Locupletissimi rerum naturalium thesauri,” vol. 3, pl. 38, figs. 46-48; vesicaria therefore becomes the specific name for the large beautiful Florida Hydatina. We are greatly indebted to Mr. Irons for bringing to our attention the decidedly distinctive characters of the Florida species as compared with those from the Orient. A large series of beautifully preserved specimens show plainly from the color scheme alone that our Florida species has nothing in common with that of the Pacific. Mr. Irons furnished me with the following interesting notes on the habits of this animal. ““Hydatina evidently spends most of its life burrowing in the silt and sand of sheltered waters. It emerges at breeding time when the egg cases are delivered and attached to small marine growths where fertilization evidently takes place.” Pavut BartTscu, United States National Museum. 1 True, F.

General Notes. 93 A SUBSTITUTE NAME FOR THOMOMYS BOTTAE OCCIPITALIS BENSON AND TILLOTSON. Professor Lee R. Dice has called our attention to the fact that he used the combination Thomomys bottae occipitalis (Carnegie Inst. Washington, Publ. 349, p. 125, 1925) in naming a fossil gopher from the Rancho La Brea deposits, California. This preoccupies usage of our name (Proc. Biol. Soc. Washington, vol. 52, p. 151, October 11, 1939) for a gopher from La Misién, 2 miles west of Magdalena, Sonora, Mexico. For the latter name we substitute Thomomys bottae basilicae. Seta B.

(95) OCT9 1940 96 Proceedings of the Biological Society of Washington. less than the interorbital distance (2.9 mm.); tympanum vertically oval, the lower rim distinctly elevated, the upper posterior part of rim concealed by skin which does not form a fold or at most only a very inconspicuous one. No vomerine teeth; choanae moderate in size, almost lateral, but not concealed by jaw when seen from below; openings of the mucous glands lie posterior to the anterior level of choanae; tongue elongate, pyriform, or the shape of a grain of maize, slightly notched behind, the posterior third (or a little less) free. (Males with well-developed vocal sacs, the openings elon- gate, forming a distinct fold or disk on the throat.) . Arm long; brought forward, nearly one-half of forearm extends beyond snout; second finger equal or minutely longer than first finger; terminal disks of first two fingers a little wider than digits; those of the third and fourth fingers nearly double the narrowest width of these digits, without or with only a faint trace of a terminal transverse groove; subarticular tubercles very large, subconical; inner palmar tubercle at base of first finger smaller than the subarticular tubercle of this finger; a large rounded median palmar tubercle, nearly double size of the inner; no outer tubercle; five supernumerary palmar tubercles on palm and base of digits, with numerous very small tubercular granules between them and between bases of digits; a very slight dermal ridge on lateral edges of digits; a small tubercle posterior to the median palmar tubercle. Leg rather short proportionally, the terminal disks of digits usually about a fourth wider than digit, smaller than those on outer fingers, with or without a trace of a transverse groove; free part of fourth finger 2.5 times free part of fifth; subarticular tubercles large, salient, conical; super- numerary tubercles on digits low, indistinct save at the bases of digits; inner metatarsal tubercle as large as the subarticular tubercle of first toe; outer metatarsal tubercle about half as large; sole of foot covered with very numerous smaller granular tubercles; when limbs are folded at right angles to body, the heels barely touch. Skin above very smooth, with faint indications of smooth pustules on back and sides; skin of ventral surface of body absolutely smooth, lacking all trace of granulation; a ventral disk present on abdomen (barely dis- tinguishable in the female type, distended with eggs, but prominent in a younger female and all the males); posterior edge of disk crosses abdomen some distance from femurs; ventral surface of femur with granulations; posterior surface of femur granular up to anus; a slight transverse fold or longitudinal swelling on femurs somewhat: below anus; anal flap obsolete, the region posterior to anus fluted, the median groove not strongly de- veloped; inguinal gland flat, indistinct, its extent can be determined by the small surface pores, or by dissection. Paratoid gland moderately distinct, its extent evident externally.

Taylor—A New Syrrhophus from Guerrero, Mexico. 97 and snout with a dark lavender band; upper lip with an irregular row of small creamy-white dots which may extend to arm; sides with some indefinite lighter flecks or spots; dull whitish on ventral surfaces lacking any trace of yellow or orange coloration. Chin, under sides of arms, femurs, tibia and feet with a thin peppering of lavender pigment scarcely discernible without a lens. This pigmentation is lacking on median part of breast and abdomen. Variation.—The large series is very uniform in size and proportions. In some of the specimens the mottling on the back is more distinct, in which case the lighter amber color may be somewhat silvery and the dark spots or flecks purplish or purplish brown. In others the mottling is so obscure as to make the back appear almost unicolor. In some specimens the inguinal gland appears somewhat yellowish beneath the skin. The exudate is usually whitish. Remarks.—Specimens were obtained on rainy nights by following the calls of the males. These were found with no inconsiderable difficulty, usually perched on boulders and limestone masses, or ensconced in holes and crevices. One was taken in a small tree; and two females were found during the daytime under rocks. The eall is a whistled chirp. It is usually given but once, and repeated only after a considerable period (often one to five minutes). The name piptlans refers to this chirping habit. I presume that the species is one of the distinctive forms of the Sierra Madre del Sur since it has not been found elsewhere. The flat inguinal gland is present in many of the species of Syrrhophus, but the large paratoid gland is usually absent. In general appearance the species seems to resemble Syrrhophus leprus but may be readily separated from that form by the presence of the paratoid gland, which I do not find in S. leprus.

BY LAWRENCE W. SAYLOR, U. S. Department of the Interior, Bureau of Biological Survey. The dung beetles comprising the so-called Cadaverinus Group of the genus Aphodius are very rare in collections, owing in part to the fact that the species are extremely local in dis- tribution. All but one of the species listed herein have been examined for wing length. The exception is A. nevadensis Horn, specimens of which were not available; but the wings of this species are said, however, to be greatly reduced. A. oblongus Say, A. gravis Fall, and A. sparsus Leconte are all fully winged; these species also have a rather long metasternum, and in these two characters are quite distinct from the other species now included in the group. Every other species treated in this paper has the wings vestigial (one-half to two-fifths of the length of the abdomen, and not as wide as the width of the hind tibiae) and the metasternum rather short (measured along the midline of the insect). This latter character has not been mentioned by other students of the group but appears to be of value since it definitely separates the fully winged from the vestigial-winged species. This is probably a direct correlation since many insects having vestigial wings possess reduced metasterna whereas their nearest-winged relatives may have well developed metasterna. Several species here dealt with have been described rather recently as new, but no key to the group has yet been presented. The key has been purposely made fuller than usual, since some of the species are rather closely related and I wish to leave no doubt in the mind of the person using the key as to the identity of the specimens.

Some years ago I was engaged in identifying a collection of reptiles and amphibians from Ceylon made by W. L. Schofield in 1933, and generously presented to the Museum of Compara- tive Zoology by Thomas Barbour. At the time I was studying this collection, I noted two apparently new species of frogs to which, because of other duties, I was unable to give attention until now. Rhacophorus dimbullae, sp. nov. Type.—Museum of Comparative Zoology no. 20878, a female, from Queenwood Estate, Dimbulla, 5000 feet, Ceylon, collected by W. L. Schofield in 1933. Diagnosis.—Allied to Rhacophorus fergusonii Boulenger,! from which the new form differs in the shape of the vomerine teeth, in possessing less webbing of the feet, and in coloration. It is also allied to Rhacophorus stictomerus (Gunther) from which the new form differs in having a larger tympanum, decidedly larger disks on hands and feet, and in coloration. Description.—V omerine teeth in two fairly long, oblique groups between the choanae starting close to their inner front edges; no papilla on the tongue; snout broad, obtusely pointed, a little longer than the diameter of the orbit; canthus rostralis distinct; loreal region concave and somewhat oblique; nostril nearer the tip of the snout than to the eye; interorbital space broader than the upper eyelid; tympanum half the diameter of the eye; first finger shorter than the second; fingers with a rudiment of web- bing; disks of fingers and toes large, those of the two outer fingers almost as large as the tympanum; toes about two-thirds webbed, somewhat less than one phalanx of the third and fifth, and nearly two of the fourth free; subarticular tubercles of feet and hands moderate; the tibio tarsal articu- 1 This is the form which E.

Diagnosis.—Allied to Philautus variabilis (Gunther) from which this new form differs in having a papilla on the tongue, more fully webbed toes, and it appears also to differ in coloration (both are variable in coloration). Description.—Tongue with a small obtusely pointed papilla in the anterior part of the median line (absent or indistinct in the four smaller paratypes); snout subacuminate, almost rounded, as long as the diameter of the orbit; canthus rostralis distinct; loreal region oblique and concave; nostril nearer to the tip of the snout than to the eye; interorbital space broader than upper eyelid; tympanum indistinct, about half the diameter of the eye; first finger shorter than the second; fingers with a rudiment of webbing; disks of fingers and toes rather large, those of the two outer fingers almost as large as the tympanum; toes about three-quarters webbed, third and fifth digits webbed almost to the disk; fourth toe with approxi- mately one and a half phalanges free (in the four smaller paratypes about two-thirds webbed, with about one phalanx of third and fifth and about two of fourth free); subarticular tubercles of feet and hands moderate; the tibio-tarsal articulation of the adpressed hind limb reaches the eye; upper parts finely granular; a fold above the tympanum; belly and lower surface of thighs granular, chest and underside of lower jaw less granular. Coloration in alcohol.—Above, orange pink, vermiculated and marked with dark gray including a broken crossband between the eyes and a very Shreve—A New Rhacophorus and a New Philautus. 107 irregular bar on the back, on each side, posterior to the head; limbs faintly cross-banded with brownish or grayish; below, whitish. Two of the paratypes are colored above very much like the type except that the cross bars at the rear of head are absent; and from near the eye to the middle of the back there is a curved longitudinal streak of dark gray, broken into spots on one example. In the type there is what is apparently a faint indication of the posterior end of these lines; legs are a little more strongly banded in both paratypes than in the type. One paratype is more densely spotted and marked on the upper surfaces than the type; the other less so. The three other paratypes are also like the type except that they are much darker above, two of them strongly suffused with gray, one of these so strongly that the ground color is almost completely hidden. The speci- men without the suffusion has a faint indication of the same markings as the two paratypes mentioned in the preceding paragraph; the two suffused examples are unmarked. MEASUREMENTS.

BY LAWRENCE W. SAYLOR. In this paper are described the following new species of Phyllophaga: Phyllophaga (? Chirodines) oaxena, new species. Male.—Elongate oval. Dull rufocastaneous, the thorax slightly shining. Above entirely clothed with short, dense, suberect, brownish hairs, those of head a little longer and more erect. Clypeus and front coarsely, rugosely, very densely and contiguously punctate. Clypeus very short, somewhat semicircular in outline though transverse, the apical margin slightly reflexed. Antenna uni-colorous, 10 segmented; club very slightly longer than the entire stem, segments 3-7 each slightly transverse. Thorax with sides entire, and straight, before and behind the moderate median dilation, with several scattered cilia; base without marginal line; front angles rect- angular to nearly subacute; hind angles obtusely angulate; disc with fine, dense, regularly placed punctures over the entire surface, with a faint suggestion of a median longitudinal carina. Elytron without stria except for the well-developed sutural stria, the latter obsolescent at base; disc subrugose, punctured as thorax. Pygidium convex, pruinose, with very fine, dense and regularly placed punctures, each with a short erect hair; apical margin explanate and somewhat reflexed. Abdomen with short, dense, suberect pile; middle widely and shallowly concave; 5th segment flattened, the apex arcuate and faintly produced, the disc with a very dense patch of fine, though somewhat transverse, granulations; 6th nearly as long as the 5th, and raised a little above it,—dise of 6th impressed transversely, apex carinate and ciliate, the base sinuate at middle and raised and pro- duced slightly, the center of the sinuation reaching apically and nearly attaining the apical margin of the segment. First segment hind tarsi shorter than the second. Hind tibial spurs acute and unequal, one two- fifths longer than the other, and slightly distorted. Transverse carina on mid tibia only about half complete, external margin not serrate; carina of hind tibia very faintly indicated and not entire. Segments 1-4 of front tarsus with the inner apex of each segment prolonged into a broadly rounded 24—Proc, Bron. Soc. Wasu., Vou. 53, 1940. (109) OCT 9 1940 110 Proceedings of the Biological Society of Washington. lobe-like tooth, that of the first segment the largest and the following becoming progressively shorter. Male genitalia small and simple, of the complete ring-shaped type, and bilaterally symmetrical. Claws of all the tarsi entirely simple, with at most a trace of a very fine serration on the lower margin; the outer claw of each front tarsus with a faint trace of a tiny tooth placed basad from the middle of the claw. Length 20.5 mm. Width 10.3 mm. The unique male Holotype, which remains in the Saylor Collection, is ~ from ‘‘Oaxaca, Mexico.”’ This very interesting species presents somewhat of a problem as to its proper place in our taxonomic sequence of subgenera and species. Its affinities approach Chirodines the closest, though I leave it here with reserve. The new species differs especially from Chirodines zuntlensis Bates (only described species in that genus) in the weak and obsolete tibial carina (as opposed to strong and entire carina), in the basically different type of genitalia, and in more minor details of the claws and pilosity of the dorsal surface. Phyllophaga (? Phyllophaga) apolinari, new species. Male.—Elongate, subparallel. Dark piceocastaneous, slightly shining and glabrous dorsally. Front and clypeus with coarse variolate punctures, those of front sparse and those of clypeus smaller and much denser. Front below vertex with a transverse gibbose elevation running from eye to eye, the surface of this subcariniform area rugosely and densely punctate, the area behind on vertex and occiput with extremely dense and very fine punctures. Clypeus very short, broad, and transverse, apex widely and shallowly emarginate, the angles very broadly rounded, margin not re- flexed; center of disc at base impunctate. (Antenna lacking in unique type.) Labrum quite large and very deeply and narrowly incised, thus appearing strongly bilobate. Sides of thorax very arcuate, the widest point just behind the middle; sides crenate in anterior half, simple behind; hind angles broadly rounded, front angles produced and rectangular; front margin not thickened, posterior margin obsolete near middle; disc with fine, moderately-sparse, irregularly-placed, and variolate punctures, these separated by one to four times their diameters on disc and closer at sides and near front, center disc with small, irregular impunctate area. Elytron with four well-marked stria in addition to the well-developed sutural stria; first stria complete, oblique, and strongly widened apically; 2nd stria parallel to first; 3rd narrow and running from the humeral umbo to the apical umbo; 4th narrow and running from the humeral umbo down to the lateral margin and then running along parallel to the latter; first three striae becoming obsolete apically at the apical umbo; disc rugosely punc- tured, the punctures moderately dense. Pygidium polished and slightly convex, punctures dense, coarse, variolate, and regularly placed; apex broadly rounded and not ciliate. Abdomen polished, gibbose, and nude at middle, the sutures hardly obvious, entire 5th segment transversely im- pressed, sparsely punctate, the sides pruinose and pilose; 6th segment three- fifths the length of 5th, flat, with moderately coarse and somewhat sparse punctures. First segment of hind tarsus distinctly longer than, and larger Saylor—Ten New Neotropical Beetles of the Scarab. 111 than, the second. Hind spurs free and graceful, the longest one much longer than the first segment of the hind tarsus. Transverse carina of hind tibia well marked and complete, the inner edge of it prolonged into a short, sharp lobe. First segment of mid tarsus equal to the next two combined; transverse carina completely lacking, evidenced only at each side margin by a sharp lobe. Inner lower edge of front femora strongly produced in- wardly into a sharp, robust ‘‘spur.’”’ All tarsi with a sharp median tooth, the base obtusely dilated. Male genitalia very peculiar for the genus: lateral lobes soldered together into a broad tube, from the lower outer apex of which emerge two long and slender projections which converge towards the center and touch tips there; aedeagus with a strong globose structure at each side, these structures projecting halfway out of the inside of the lateral lobes and tip of each with a sharp tooth which projects outwardly. Length 29 mm. Width 14.5 mm. The unique male Holotype, in the Saylor Collection, was given to me by Mr. Apolinar-Maria who collected the specimen at ‘Saigon, Columbia.” Although this species appears to be more similar to certain Oriental forms of the genus, I do not doubt that it is correctly labeled since I received it unmounted from the collector along with a number of species all of which were without doubt of Columbian origin. I leave it in the present sub- genus with much doubt, since the non-carinated middle tibia, the very differ- ent type of male genitalia and the subcarinate vertex, appear to mark out a definite group of its own. Phyllophaga (Phyllophaga) rolbakeri, new species. Male.—Elongate, subparallel. Black, legs somewhat rufopiceous. Moderately shining above and apparently nude. Clypeus and front very densely, coarsely and entirely punctate; upper half of front and vertex impunctate. Clypeus shallowly and widely emarginate apically, the angles extremely broadly.rounded. Antenna 10-segmented; club small and ovate, equal to segments 4-7 combined. Thorax with sides subparallel behind the median dilation and nearly entire; front and hind angles nearly rectangular; basal margin widely interrupted at middle; disc with an irregular longi- tudinal smooth area at middle, remainder with moderately dense, coarse, and umbilicate punctures. Each elytron with two striae other than the sutural; sutural stria slightly narrower at base, first stria oblique and very distinctly wider apically, the second stria of nearly equal length throughout and also obliquely placed; dise punctured as thorax and somewhat rugosely so. Pygidium convex, rugose, the punctures coarse, umbilicate and some- what sparse, with very small and erect, sparse hairs. Abdomen moderately convex, highly polished and nude at middle; 5th segment slightly trans- versely impressed just before the apex, with moderately dense and some- what fine punctures at middle; 6th segment one-half length of 5th, and transversely impressed and the surface minutely granulate. All claws with a strong, long, median tooth, the basal dilation rectangular. First two segments of front tarsi each with a small spine at inner apex. Second segment of tarsus of hind leg slightly longer than the first. Hind spurs free 112 Proceedings of the Biological Society of Washington. and graceful. Mentum with a moderately-wide, well-marked, V-shaped impression. Male genitalia simple, bilaterally symmetrical, and the two lateral lobes slender and somewhat parallel moderately widely separated at apex. Length 26mm. Width 11.7 mm. The unique male Holotype, from “‘Buena Vista, Encantada, Coahuila, Mexico, 6000 feet, July 7, 1938, R. H. Baker collector” is in the Saylor Collection. This fine species, which is nearest atra Moser but quite distinct from it, is named for my good friend Rollin H. Baker, of Texas, who collected and presented the specimen to me.

Pygidium apparently nude, faintly convex; disc very rugose and with sparse and umbilicate punctures, these punctures very dense along the basal margin. Abdomen strongly convex, polished, nude at middle and with fine, moderately dense punctures; 5th segment declivous apically, with a small patch of coarse punctures at center, apical one-fourth of segment transversely impressed; 6th segment shorter than 5th and transversely impressed and rugosely wrinkled. Claws short and with a strong, median, rather long tooth, the basal dilation small but rectangularly produced. Hind tibial spurs free, graceful. First two segments of hind tarsi subequal in length. Mentum very widely and longitudinally sulcate, the edges subcarinate. First two segments of front tarsi with very short inner apical spines. Male genitalia large and rather peculiar in shape, though bilaterally symmetrical; in addition to the two long and slender lateral lobes there is an overhanging (in en face view) lobe arising from the upper margin of the “‘ring”’ and reaching three-fifths the length of the lateral lobes; the aedeagus is very large and heavily chitinized. Length 26 mm. Width 12.5 mm. The unique male Holotype, from ‘‘ Mexico,” remains in the Saylor Col- lection. The species is abundantly distinct from all described Phyllophaga known to me, but is probably nearest atra Moser in its affinities. Phyllophaga (Phyllophaga) abcea, new species. Male.—Oblong-oval, wider behind, testaceocastaneous, the head and thorax rufous.

Male genitalia with the lateral lobes prolonged, subparallel, and not quite contiguous at tips; upper center of the ring formed by the lateral lobes with a broad projection reaching over and nearly to the tips of the lateral lobes, the apex of this projection widely lobate at each outer apical angles and the center of the projection slightly longitudinally channeled. Length 14mm. Width 7 mm. The unique male Holotype, from “‘Guatemala,’”’ remains in the Saylor Collection. It is most closely related to P. parumpunctata Bates, from which it may be separated by the dorsal pilosity, abdominal characters, larger antennal club and male genitalia. ?

Pygidium convex, the surface pruinose at base, and polished apically; punctures rather regularly placed, moderately dense, and moderately coarse, the basal area with short and erect hairs. Abdomen flattened and pruinose at middle; 5th segment plane; 6th segment one-half the length of 114 Proceedings of the Biological Society of Washington. the 5th and with a conspicuous longitudinal sulcus. First segment of hind and middle tarsi slightly longer than the second. All claws similar, each pectinate along a single margin, the pectinations rather small, and without any larger intercalated teeth. Male genitalia bilaterally symmetrical, and of rather simple design, the lateral lobes subparallel and contiguous at tips but not joined, their apices bluntly but acutely rounded. Length 10.5 mm.

Abdomen flattened, faintly concave at middle and semipolished; 5th segment with a slight longitudinal median sulcus in the apical portion; 6th with distinct longitudinal sulcus. All claws pectinate along a double margin, the pectinations of moderate size and each claw with a larger, narrow, intercalated tooth at about the middle. First segment of the hind tarsus subequal to, or faintly shorter than, the second. Male genitalia bilaterally symmetrical, the lateral lobes (in en face view) subparallel but not contiguous at apex, and each with a blunt triangular tooth arising from the upper margin and situated just before the apex, this tooth pointing outwardly from the center; sides of each lateral lobe concave.

Baker,” and were presented to me by the collector. They remain in the Saylor Collection. This species is most closely related to texensis Saylor, but can be distinguished by the non-impressed abdomen, less convex pygidium, much more obvious elytral striae and the different male genitalia. Phyllophaga (Phytalus) guatemala, new species. Male.—Elongate, subparallel. Strongly shining and apparently glabrous above. Color rufotestaceous, the head and thorax rufous.

This species differs from all described Phytalus known to me in the presence of the long and curved hind spur, much as in our Phyllo- phaga hamata and P. torta. Phyllophaga (Phytalus) oaxaca, new species. Male.—Oblong ovate, shining and glabrous above. Color rufocastane- ous, the thorax more rufous.

Elytron with or without striae other than the well-developed sutural stria,—often with a second stria weakly indicated; disc with fine and very sparse punctures, these denser at sides. Pygidium polished, slightly convex, and apparently glabrous; disc with moderately sparse and variolate punctures. Abdomen polished and glabrous at middle, and slightly gib- bose; 5th segment with a wide, shallow, and declivous fovea starting at the center base, the surface of the fovea with fine, dense, transverse granula- tions, the sides of the fovea raised and semi-carinate; 6th segment one- Saylor—Ten New Neotropical Beetles of the Scarab. 117 third the length of the 5th, and transversely impressed, the apical and basal margin faintly carinate. All claws finely cleft, the upper tooth as long as, and slightly broader than, the apical, the tip of the upper tooth obliquely truncate. Hind tibial spurs free and graceful. First segment of hind tarsus shorter than the second. Male genitalia very simple, bilaterally symmetrical, somewhat tube shaped, though short. Female.—Pygidium flatter, and slightly more densely punctate; abdomen with 5th and 6th segments plane and densely punctate; antennal club moderately long and equal to segments 3-7 combined; second costa of elytron usually well indicated and widening considerably in the apical third. Otherwise asin the male. Length 11-14.5mm. Width 5.2-7.8 mm. The Holotype male and Allotype female, and numerous Paratypes, from “Oaxaca City, Oaxaca, Mexico, 5000 feet, July 16-25, 1937,” and collected for me by Al Meade and Mel Embury, remain in the Saylor Collection. Paratypes will be deposited in the United States National Museum. This species is closely related to nubipennis Bates, but may be separated by the non-wrinkled and less densely punctate pygidium, much less densely punctured elytra and less obvious striae (1st stria, if present, indistinct and broad, not distinct and very narrow), more coarsely crenate thoracic margins in the apical half, much more distinct and deeper 5th abdominal fovea, and somewhat different male genitalia. eens a ; Brae ieee) 7.06 75 Vol. 53, pp. 119-124 October 7, 1940 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON PALATAL SESAMOID BONES AND PALATAL TEETH IN CNEMIDOPHORUS, WITH NOTES ON”... THESE TEETH IN OTHER SAURTAN' Sait GENERA. BY EDWARD H. TAYLOR. \\) ~~ | In studying the prepared skulls of lizards belonging to ~~~ Cnemidophorus and Ameiva I have noted the presence of a pair of small sesamoid bones lying below the pterygoid processes of the basisphenoid, and often extending over the edge of the pterygoid. When the surfaces were moistened the elements were easily movable proving that they were not ankylosed to the palatal bones. A few specimens of preserved alcoholic specimens were dissected and it was found that these bones were imbedded in what appeared to be a muscle tendon which attaches to the inner edge of the pterygoid anterior to the point of contact of the pterygoid process and the pterygoid bone. The dorsal surface of the sesamoid thus moves over the surface of the palatal bones and when dried they adhere to their sur- faces. When the tissues are eaten away by dermestid larvae the sesamoids appear to be an integral part of the palate. These elements, first observed in Cnemidophorus guttatus from Guerrero, Mexico, were found to be also present in the skulls of C. sexlineatus, burti, tessellatus, perplecus, gularis, grahami, deppit, melanostethus, and likewise in many unidentified skulls. They were not absent in any of the 106 skulls examined although occasionally they were detached. They were present in Ameiva undulata which is the only species of that genus available to me at present. I have examined some 200 skulls of lizards belonging to other families, all prepared by the same (dermestid) method and in none do I find sesa- moid bones present. In ten alcoholic specimens dissected, I was likewise unable to demonstrate their presence in the palatal region. In several genera of lizards I find a small ossified element intercalated 25—Proc. Brox. Soc. WasxH., Vou. 53, 1940. (119) OCT 9 1940 = 120 Proceedings of the Biological Society of Washington. between the end of the pterygoid process of the basisphenoid and the pterygoid bone, which has the appearance of an epiphysis. In some cases this adheres to the process and if, as may occur (Phrynosoma) the process does not contact with the lateral groove on the pterygoid but has a free edge exposed, this may assume the appearance of the sesamoid of the Tetidae. I do not believe, however, that they are in any sense homologous. In a skull of Varanus this element appears to be ankylosed to the pterygoid rather than to the end of the pterygoid process. What the history or significance of this small element is I can not say. The presence of palatal teeth in modern Sauria has been regarded as being of significance in determining whether a given species or genus was primitive and ancestral, or recent and derivative. Camp (1923) states: ‘““T should consider the simple presence of teeth on the palate as paleotelic. Such teeth would seem to be ancestral owing to lack of development in secondary lines of decent and prevalence of teeth in greater numbers in certain more ancient forms.”’ Since there are available here at Kansas University two collections of saurian skulls Kansas University Collection! KU and the E. H. Taylor- H. M. Smith Collection, EHT—HMS, which together number nearly 400, I have examined them for data on palatal teeth. In the literature dealing with these teeth there are certain contradictory statements and certain errors, which the following data will help to interpret or correct. TEIIDAE. Cnemidophorus. Concerning the Teiidae, Cope (1900) quotes Boulenger as follows: ‘‘Pterygoid teeth are but seldom present, and if so but feebly developed.”’ In Cope’s osteological description of Cnemi- dophorus he makes no mention of the presence of teeth on the palatal bones. Camp (1923) gives but little concrete information on this point stating that according to authors cited pterygoid teeth are present ‘‘in some teiidae”’; and later he states that the palate appears to be toothless ‘‘in some Teiidae.”’ Burt (1923) in his description of the genus Cnemidophorus states specifi- cally and erroneously that there are no palatal teeth in the genus. I have 106 Cnemidophorus skulls available. These include nine or more species. Teeth are present on the palates of all species and in all individuals save one or two specimens (or where the pterygoid is missing or the teeth have been removed in cleaning the skull). One case where teeth are want- ing is that of a very young specimen. The species here listed have the following pterygoid tooth formulae (although all specimens have been examined only formulae of those with certain identifications are included): Cnemidophorus perplecus (New Mexico and Arizona): 4-4, 2-2, 3-4, 5-6, 7-6, 6-4, 4-4, 4-5. In a very young Texas specimen I found no trace of pterygoid teeth. Cnemidophorus gularis (Southern Texas): 3-3, 2-2, 4-2, 2-1, 3-2, 3-2, 4-3, 4-2. Cnemidophorus grahami (Western Texas): 3-3, 3-3. Cnemidophorus sexlineatus (Kansas and Texas): 3-3, 3-3, 1-1, 2—?, 3-2. 1 I am indebted to Mr. Charles D. Bunker, assistant curator, for privilege of studying material in the Kansas University Collection. Taylor—Sesamoid Bones and Teeth in Cnemidophorus. 121 Cnemidophorus tessellatus tessellatus (Western Texas to Arizona): 3-2, 3-2, 2-3, 3-3, 4-5, 3-4, 3-3. Cnemidophorus melanostethus (Southern Sonora): 3-3, 0-0, 2-2, 2-2, 318) 4-8,.4-3.4-4 9-2 9-1. Cnemidophorus guitatus (Morelos and Guerrero) : 3-1, 2-2, 2-2, 3-4, 3-2. Cnemidophorus deppiit (Guerrero and Colima): 2-2, 2-3, 3-?, ?-?, 6-5, 5-6, 3-4, 3-2, 3-3, 2-0. Ameiva: Only two prepared skulls of wndulata are available. In one of these the pterygoid teeth are absent (some evidence that teeth have been present), the other has one tooth on one side, and none on the other. HELODERMATIDAE. JHeloderma. Boulenger (1885, p. 300) states, concerning this genus, ‘‘teeth on the pterygoid and palatine bones.”’ In three skulls of Heloderma suspectum Cope examined, I find the pterygoid formulae, 2—2, 2-2, 0-2 (much worn). No palatine teeth are present and there are no indications on the bone that teeth had ever been present. All are adult. A single preserved specimen of Heloderma horridum from Morelos has the pterygoid-palatine formula: 5-5, 1-1. The palatine teeth are near the posterior part of the bone and not far from the pterygoid series. ANGUIDAE. Ophisaurus. Hilgendorff (1885) and Camp _ (1923) report the presence of teeth on prevomers and pterygoids of certain species of this genus. Camp states, (p. 365) ‘‘Ophisaurus, having the most denti- gerous palate of all living lizards, is the only recent genus known to have prevomerine teeth? (df. Briihl, 1875-1888.)”’ Five specimens of Ophisaurus ventralis from Kansas show the following formulae for the pterygoid, palatine and prevomers respectively: 17-19, 5-6, 0-0; 27-24, 3-2, 0-0; 19-16, 3-2, 0-0; 9-11, 3-2, 0-0; 14-16, 3-3, 0-0. The pterygoid teeth are arranged in two or three irregular rows. The limited number of data on the absence of the prevomerine teeth in this species is not conclusive, but suggests strongly that they are absent at least in adults. IGUANIDAE. Crotaphytus. Camp (1923, p. 365) states, ‘‘Genera of Iguanidae with such [pterygoid] teeth are given in Boulenger 1885: Crota- phytus 1 species with, 1 species without, Sauromaulus hispidus, Dipso- saurus ...”’ The following formulae were found in specimens examined: Crotaphytus wislizenii. Pterygoid teeth are 4-5; palatine teeth, 1-2. Only a single adult specimen from Boise, Idaho, was examined. Crotaphytus reticulatus. This has a pterygoid formula of 15-12. I found no trace of palatine teeth in this adult specimen, from Starr Co., Texas. Crotaphytus collaris collaris. Both pterygoid and palatine teeth are present in this form. A series from a single locality in Greenwood Co., Kansas, has the following formulae for the pterygoid and palatine teeth respectively (arranged from young to old): 3-3, 0-0; 6-6, 0-0 9; 6-7, 1-0 9; 7-7, 0-0; 10-7, 3-2; 8-10, 4-3; 12-11, 1-1; 12-14, 2-1. In the last two specimens some of the palatine teeth apparently have been lost, as 2 Prevomerine teeth have been reported by Kingman (1932) as occurring in HLumeces (Scincidae). ‘‘At the posterior end of the plate near the median groove is found a pair of tooth-like processes that may be considered the homologue of prevomerine teeth.” 122 Proceedings of the Biological Society of Washington. evidenced by the presence of shallow grooves. Certain other specimens from various Kansas localities have the following formulae: 17-14, 3-3; 12-6, 0-07, 16-16, 0-0 co"; 16-10, 2-0 9 ; 24-21, 2-5; 13-19, 2-3. Crotaphytus collaris baileyi. The formulae for a young specimen is, 4-4, 0-0; for an adult 18-13, 2-1. Camp, loc. cit., lists this form as lacking teeth. This statement may be true of some younger specimens. In this genus it appears that the pterygoid teeth are acquired gradually from youth to adult age. The palatine teeth appear to be acquired at a later time and in some cases seem to be partially or totally lost with old age. Dipso-saurus. A single form, dorsalis sonoriensis, lacks all trace of palatine teeth. The pterygoid teeth are as follows, in a series of skeletons from the type locality: 3-2, 0-0, 2-1, 4-2. Sauromaulus. Camp reports pterygoid teeth present in Sawromaulus hispidus. In an old specimen of Sauromaulus townsendi from Guaymas Sonora, I find the following pterygoid formula: 1-0. Sauwromaulus obesus. Three specimens from Arizona have the following pterygoid formulae: 6-8, 8-7, 0-1. Holbrookia. Fifteen specimens belonging to seven forms of this genus show no trace of pterygoid or palatine teeth. Uta. Twenty-nine specimens examined belonging to 11 species show no trace of any palatal teeth. Sceloporus. Eighty-two specimens belonging to twenty-six species show no trace of palatal teeth. Phrynosoma. Six specimens belonging to five species lack all trace of palatal teeth. i Basiliscus. Specimens of Basiliscus vittatus examined have no palatine teeth. The pterygoid teeth are, 6-1+ 07; 5-7 9; 5-5. Iguana. A single skull of Iguana rhinolopha has the pterygoid teeth in a short, transversely curved group, 5-6. No palatine teeth are present. Ctenosaurus. Bailey (1928) states in his diagnosis of this genus, “‘ptery- goid teeth present.’’ Two specimens of C. acanthura have the following formulae: 12-4; 21-23. These are arranged in a double row. There are no palatine teeth. Anolis. This genus is reported by Boulenger and Camp as having some forms with pterygoid teeth, some without. Two Mexican species exam- ined, nebulosus and nebuloides, show no pterygoid or palatine teeth. SCINCIDAE. EHumeces. Kingman (1933), has recorded the presence, and given figures, of the occurrence of pterygoid and vomerine teeth in this genus, based largely on the collections mentioned in this paper. I can add another species (Humeces copet) which has a formula 2-2 for the pterygoid, and 1-1 for the vomerine teeth (in this specimen the processes do not appear to be enamel covered). Mabuya. I have examined only the Mexican species, Mabuia agilis, of this genus. In this single specimen there is no trace of palatine teeth. Leiolopisma. In a single skull of L. unicolor, I find no trace of palatine teeth. Proc. Brot. Soc. Wasu., Vou. 53. PuaTte II Puare Il.—Taytor, Palatal sesamoids and palatal teeth in Cnemidophorus.

BY EDWARD H. TAYLOR AND IRVING W. KNOBLOCH. The material on which the following report is based was collected by one of us (Knobloch) during the summer of 1939. Since the fauna of the Sierra Madre Occidental is but little known it seems important that the following records be pub- lished. A specimen of Crotalus, perhaps related to lepidus and a small series of Ambystomid larvae await further study. Two forms, an Eleuthero- dactylus and a Lampropeltis are believed to be new, and are described elsewhere! by the senior author. (Numbers refer to the E. H. Taylor- H. M. Smith collection). Bufo simus Schmidt. Bufo simus Kellogg, Bull. U.S. Nat. Mus., No. 160, 1932, pp. 63-68, fig. 14. Several specimens in the collection Nos. 18485, 23020-23025 belong to a form which has the tympanum concealed. When more specimens are available from Western Mexico it may be possible to demonstrate that Bufo monksiae Cope? is a legitimate species to which the present specimens may be referred.

The crown of the head is a little broader and the head somewhat shorter than in a specimen from near Mexico City. These specimens give no evidence of a closer approach to Phrynosoma douglassii hernandesi or P. douglassit douglassii than do specimens from the southern part of the plateau that are available tome. And in consequence I am inclined to question the wisdom of associating douglassiz and hernan- desi as subspecies of this species. Holbrookia maculata approximans Baird. A single, very young specimen, No. 23048, is in the collection. It is referred with some hesitancy to this species, since adult color and markings are wanting. Sceloporus jarrovit jarrovit Cope.

Gerrhonotus nobilis Cope, Rept. U. 8. Nat. Mus., 1898 (1900), pp. 519-520, fig. 92. This series of five specimens, Nos. 18982, 23026-23029, agree in pertinent detail with the figure given by Cope (loc. cit.) of an Arizona specimen. There are 14 or 16 longitudinal rows of enlarged dorsal scales, there being strong variation in the size of the outer row of scales. The number of dorsal dark bands varies from 10 to 13 (youngest specimen). This latter specimen (No. 18982) has the transverse dark bands with the white edge usually confined to a single row of scales, although medially the darker part may encroach on the preceding scale row; the four larger specimens have the dorsal blackish or blackish-brown bands usually covering two whole rows and often one or two half rows as well. On the sides the bands are usually confined to two scale rows, rarely covering the whole of them. The groove of the lateral fold is largely black, and some faint blackish spots are dis- cernible immediately below the fold. The ground color above varies from olive-gray to gray, occasionally with a faint reddish brown shade discernible. The head is variously marked with black; the side of head below eye whitish or cream with some black spots. Below the color is lemon yellow on under- side of abdomen and tail; chin, throat and breast cream. There are some minute grayish flecks, but there are no distinct dark spots on each scale as is true of Arizona specimens. Cnemidophorus perplexus Baird and Girard. A single specimen of the species (No. 29061) is present in the collection. Eumeces callicephalus Bocourt.

(Diag- nosis states the adpressed limbs do not touch. However, in medium sized males the toes may touch). The single specimen No. 23019 in the collection agrees with the charac- ters recorded by Taylor (op. cit.). The postnasal is present on both sides; there are seven upper labials (the postlabial scale is large, elongate and may be mistaken for an eighth labial); the black stripe on the side which contin- ues to base of tail is on parts of three scale rows but not more than two scale rows wide; the light stripe on labials continues through the ear, and can be traced as a grayish silver line to the hind leg. Dorsal color greenish gray, somewhat browner anteriorly; chin and throat white; head lines join on the nuchals, of which there are two on one side and three on the other. 128 Proceedings of the Biological Society of Washington. Eumeces parviauriculatus Taylor. Eumeces parviauriculatus Taylor, Proc. Biol. Soc. Wash., XLVI, Oct. 26, 1933, pp. 178-181, fig. 2; Univ. Kansas Sci. Bull., 1935 (1936), pp. 368-371, plate 31, fig. 5; text figs. 59, 61. Two specimens are referred to this species, No. 18984, certainly, and No. 18983 with some doubt, since the latter lacks the head. The first specimen agrees with the type (figured loc. cit.) save that the frontonasal is larger and forms a very broad suture with the frontal; in consequence the prefrontals are distinctly smaller. Probably the most distinctive characters of the species is the very large anterior temporal, the still larger lower secondary temporal, which exceeds the upper secondary in size, and the consequent reduction in the size of the sixth and seventh labials. These characters are clearly defined in this specimen. There is an ear lobule distinguishable, which was not observed in the type. There are twenty scales about body; 68 scales from parietals to above anus; and 24 scales about constricted part of neck. The specimen, preserved in formalin, is grayish black, the dorsolateral white lines visible from the snout to the base of the tail. The black lateral stripe is distinct to above the hind leg. The lateral white stripe beginning on the anterior labials extends only to arm, passing through lower half of ear; the very short limbs when adpressed are separated by about 18 scales. The subcaudal scales are not or but very slightly larger than adjoining scales. The snout to vent length is 57 millimeters. The headless specimen has a clear bluish-gray coloration above with a greenish-white dorsolateral line. The black stripe on side is about 3 scales wide on the neck but only about the width of two scales posteriorly. The tail is grayish blue above and below; neck creamy-white the belly grayish. The limbs adpressed are separated by 18 scales. The body is extremely slender, its greatest width being 4.6mm. The distance between axilla and groin is 22 millimeters. The length of the tail is 61.4 millimeters. There are 20 scales around middle of body. Despite the absence of the head I have but little hesitancy in regarding it a young specimen of this species.

A single juvenile specimen No. 23018 agrees fairly well with the type description save that there is a small loreal present. Both Giimther and Boulenger confuse with this species certain other species of the genus, especially the Oxyrhina varians Jan. This latter form is variable and is widespread, occurring in Hidalgo, México, Veracruz, Tlaxcala, Puebla, Morelos, Distrito Federal, Guanajuato, Michoacan and Jalisco. Taylor and Knobloch—Report on Herpetological Collection. 129 C. nasus is known from Michoacan, Jalisco, Guanajuato and Durango and overlaps the territory of varzans in the southern part of its range. The two difier greatly in size and in dorsal and ventral coloration, and markings. I have seen only one specimen of varians (in more than 100 specimens), with the internasals and prefrontals fused—this a specimen from far out of the range of nasus. I have seen no specimen of nasus (with the median, dorsal, dark quadrangular spots, and with the dark quadrangular marks on the ventrals) that failed to have them fused (20 specimens). The two forms may occur on the same hillsides in the same identical habitats (under rocks). It is probable that with an accumulation of specimens, subspecific forms may profitably be separated in both species. The specimen recorded here is the most northern record. Ventrals, 126; _ subcaudals, 34; such differences as obtain between this specimen and other specimens I have from other parts of Mexico, may be due to age (i. e., shorter, slightly less pointed snout).

A large female specimen (No. 23062) was collected at Moguarichic, Chihuahua. It was found dead and partly eaten, so that the continuity of the ventral scale series is broken. The squamation of the head is typical. Thamnophis eques (Reuss). Six specimens of this species have been collected. These are Nos. 18962, 18963 and 23063-23066.

Atomarchus multimaculatus Cope, Amer. Nat. 1883, pp. 1300-1301. This form, which Cope designated as the type of a new genus, has for a number of years been regarded as a synonym of Thamnophis angustirostris Kennicott. An examination of the type of the latter species shows this relationship does not exist. The single specimen present, No. 23015, has a median postrostral scute 130 Proceedings of the Biological Society of Washington. separating the nasals, and likewise separating the internasals from the rostral. This contains a deep circular pit; a pair of pits are present in the parietals. This is regarded as probably anomalous, since the presence or absence of the median postrostral varies. In a specimen in the National Museum the pit is present in a specimen from Arroyo del Alamas, 70-74 km. south of Nueva Casas Grandes, Chihuahua, México (No. 42874). The pit is present in the postrostral scale, but the pits are lacking in the pari- etals. The general appearance of the snake is far more like Natriz than Thamno- phis. It may be a Natrix with a fused anal. Tantilla wilcoxi Stejneger. Tantilla wilcoxi Stejneger, Proc. U. S. Nat. Mus., 25, 1902, p. 156 (type description; type locality Fort Huachuca, Arizona). Four specimens of this rare species (Nos. 18967-18970, are in the col- lection, and are, I believe, the southernmost records. The following data apply to the above specimens respectively: «7, 2, 9, 2; ventrals, 155, 164, 159, 159; subcaudals, 62, ?, 67, 64; mental touches chinshields; nar- rowly on one side; narrowly on one side, broad contact with both, broad contact with both. This data with that given by Blanchard (Zool. Series Field Mus. Nat.

Pericrocotus peregrinus sacerdos, subsp. nov. Type.—Male, U.S. National Museum, No. 360,788, Sambor, Cambodia, January, 1940. Similar to Pericrocotus peregrinus vividus Baker, but more deeply colored below, on the rump, and on the tips to the outer tail feathers; size slightly smaller. Wing, 70; tail, 67.5; culmen, 11. Remarks.—This form is founded on three males from Cambodia and a pair from the Langbian Plateau, southern Annam. These have been com- pared with a good series from Siam and Tenasserim. The male from the Langbian Plateau is in a bleached post-breeding season plumage and is indistinguishable from Siamese males, but I am placing it with the Cam- bodian series on size. The three males from Cambodia and one male from South Annam measure: wing, 67.5-70.5 (69.4); tail, 67.5-68.5 (67.9); culmen, 10.5-11 (10.7). Ten males from Tenasserim (3) and Siam (7): wing, 67-75 (71.7); tail, 69-76 (72.6); culmen, 10.5-11 (10.8). The single female from the Langbian Plateau does not differ appreciably in color from the same sex from northern and central Siam, except in size, being some- what smaller. 1Published by permission of the Secretary of the Smithsonian Institution. 27—Proc. Biou. Soc. Wasu., Von, 53, 1940. (131) 5 on . 1 \\ Qn 132 Proceedings of the Biological Society of Washington. Dicrurus leucophaeus rocki, subsp. nov. Type.—Male, U. S. National Museum, No. 360,828, Arbré Broyé, South Annam, October, 1939. Similar to Dicrurus leucophaeus mouhott, but averaging slightly darker and considerably smaller in size. Also similar to Dicrurus bond but darker and the black bristle-like feathers across the forehead well developed. Wing, 137; tail, 128; middle tail-feathers, 91; culmen, 22. Remarks.—This form is founded upon seventeen specimens from the Langbian highlands of South Annam which have been compared with a good series of Dicrurus leucopaeus mouhoti, mostly from northern and southeastern Siam, and four specimens of Dicrurus bondi (including the type). The measurements of the three forms are as follows: Ten males from northern and southeastern Siam: wing, 138-143 (140); tail, 136-151 (142.8); middle tail-feathers, 93.5-107.5 (99.3); culmen, 22.5-24 (23.2). Hight males from South Annam: wing, 129.5-138 (134.6); tail, 118-135 (128.3); middle tail-feathers, 81-99 (91); culmen, 19.5—-22 (20.9). The three males of Dicrurus bondi: wing, 127-134 (131); tail 114.5-120 (118); middle tail-feathers, 86-94 (89.3); culmen, 20-21 (20.5). Walden (Ann. & Mag. Nat. Hist., ser. 4, vol. 5, 1870, p. 220) described Buchanga mouhoti from Cambodia as darker than B. lewcophaea, when the opposite is the case. I believe this type must have been an immature specimen. His measurement of the wing is too short and of the middle tail-feathers too long. As no specific type locality was given, I would definitely designate Angkor, Cambodia, as the type locality. Named in honor of Dr. Joseph F. Rock, who has done so much for the botany and ornithology of the East. Drymocataphus albiventer vicinus, subsp. nov. Type.—Male, U. 8S. National Museum, No. 360,926, Fimnon, South Annam, November, 1939. Similar to Drymocataphus albwenter connamomeus, but the throat is more extensively white, the hastate markings on the throat more pronounced and blackish rather than brownish; sides of face more grayish; color above and below, averaging lighter; culmen longer. Wing, 56; tail, 48; culmen, 14. Remarks.—The present form is founded upon six specimens from the Langbian region of South Annam, but only a pair has been available for comparison of Drymocataphus albiventer cinnamomeus. While the two forms are separated widely geographically, they are remarkably alike in color. Stachyridopsis ruficeps paganus, subsp. nov. Type.—Male, U. S. National Museum, No. 360,911, Fimnon, South Annam, November, 1939. Similar to Stachyridopsis ruficeps davidi from Szechwan, but a lighter, brighter yellow below; pileum lighter, more yellowish rufous; upperparts lighter, grayish olive, instead of citrine drab. Wing, 54; tail, 50.5; culmen, 13. Remarks.—The present form is founded upon two males and two females Riley—Six New Forms of Birds from Indochina. 133 from the Langbian region of South Annam. ‘These have been compared with nineteen specimens of S. r. davidi from Szechwan. The female is much lighter below than the male, olive buff, very lightly washed with chartreuse yellow, the throat with fine dusky streaks. It differs in the same way as the male in a lesser degree. There is little or no difference in size between the two forms. Pycnonotus finlaysoni eous, subsp. nov. Type.—Male, U. S. National Museum, No. 360,964, Col. des Nuages, Quinhon Road, Central Annam, January, 1940. Similar to Pycnonotus finlaysoni finlaysoni from the Malay Peninsula, but the underparts grayer, the crissum and under tail-coverts averaging a deeper yellow; upperparts darker; closed wing outwardly a more greenish yellow. . Wing, 78.5; tail, 73; culmen, 15. Remarks.—Of the present form, the series consists of one male from the Langbian Plateau, three males from the type locality, two males and one unsexed from Cambodia. These have been compared with a good series from the Malay Peninsula and a large series from Siam. The specimens from the lower Malay Peninsula have a brownish tinge to the lowerparts, especially on the chest, rarely found further north in the upper part of the Peninsula. Specimens from eastern Siam grade towards the present form if they should not actually be placed with them. There is little or no differ- ence in size between the two forms. Microscelis psaroides impar, subsp. nov. Type.—Male, U. 8. National Museum, No. 360,989, dense forests south of Dalat, South Annam, October, 1939. Similar to Microscelis psaroides concolor but smaller and averaging lighter on the back. Wing, 121; tail, 98; culmen, 21.5. Remarks.—This form is founded upon fourteen specimens from the mountains of South Annam and has been compared with thirty-seven specimens from Siam, six adults from Yunnan, three specimens from French Laos, and one specimen from Tonkin. Ten males from northern Siam measure: wing, 125-134 (128); tail, 102-113 (106); culmen, 24-26 (24.8). Seven males from South Annam: wing, 115.5-125 (121); tail, 89.5-105 (97); culmen, 21.5-24 (22.6). The females are smaller than the males and the differences in this sex are not so great. Ten females from northern Siam measure: wing, 116—123.5 (119.6); tail, 94-105 (98.7); culmen, 21-25 (22.7). Seven females from South Annam: wing, 113.5-118 (115.6); tail, 88- 97 (90); culmen, 21—23.5 (22.3). Only four of the Yunnan specimens are sexed, three as males. They are slightly darker above than the northern Siamese series, but upon measure- ment agree with them. The differences, if there are any, are too slight to be recognized by name. The Laos and Tonkin specimens are in bad shape and not suitable for comparison, but they probably belong with the northern form. sm Ri ; me A de md Vol. 53, pp. 135-154 December 19, 1940 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON EIGHTH SUPPLEMENT TO THE FLORA OF THE DISTRICT OF COLUMBIA AND VICINITY. BY W. L. McATEE. In view of plans for a manual of the flora’ of a greatly enlarged region, including the area that has usually been adopted for publications on plants of the District of Columbia and vicinity, it seems desirable to summarize progress of knowledge since issuance of the Seventh Supplement* ten years ago. In the preparation of that publication and the present one, the writer has acted as a compiler only. He is not an expert botanist and owes much to the contributions of numerous individuals men- tioned in the text. He is especially indebted to Neil Hotchkiss, F. J. Hermann, and 8. F. Blake for critical comment as well as for notes on the flora. Doctors Hermann and Blake also have kindly gone over the manuscript and made numerous useful suggestions.

Section I includes references to descriptions of new forms based in part upon local material but not to apparent additions resulting from nomenclatorial changes. Many of the latter were collected but they have been omitted to conserve printing funds. Section III, however, includes references to changes in names in connection with which locally collected specimens were defin- itely cited.

Separate collections by Shreve and Morris are listed. Morris recorded his find in the Proceedings of the Biological Society of Washington xiii, pp. 157-158, 1900, but as the plant has not been included in publications on the D. C. flora, the locality must have been considered outside of the accepted limits. It is, however, within a 20-mile radius, so this record for a plant of a subgenus otherwise unrepresented in the local flora may well be recognized. Thlaspi perfoliatum L.

Lespedeza stipulacea Maxim. Plummers Island, Md., Sept. 19, 1937, E. P. Killip. P. L. Ricker states that this species is becoming established at several places in the region. Polygala verticillata L. A race with smaller floral parts and fruits from a range including the District of Columbia is described by M. L. Fernald (Rhodora 40, 4 While recording the conclusions of these later botanists, let us not forget the pioneer work of E. 8. Steele who understood the diversity in species of Rubus before other Wash- ington botanists were prepared to accept it.

Specimens recorded are from near Cabin John, Md., Aug. 1, 1920, Maxon; and High Island, D. C. (should be Maryland), June 23, 1897, Holm. Potamogeton panormitanus Biv. var. major Fischer. This form confused in the past with P. pusillus includes most of the local material assigned to that species (M. L. Fernald, Mem. Gray Herb. 3, 1932, p. 61). This author lists the following local collections: Flats of Potomac River opposite Alexandria, G. H. Shull; Hunting Creek, Va., McAtee; Dyke, Va., Metcalf and Sperry. Potamogeton epihydrus Raf. Two varieties are recognized by M. L. Fernald (Mem. Gray Herb., 3, 1932, pp. 113-123), of which var. nuttallii (Chamisso & Schlech- tendal) Fern. is recorded from Maryland and Virginia localities near the District of Columbia. Potamogeton zosteraefolius Schumacher. This is a European species from which the American is distinct. The latter is described as P. zosteriformis n. sp., in part from local material by M. L. Fernald (Mem. Gray Herb. 3, 1932, pp. 36-40): Hunting Creek, Va., Shull, McAtee; Dyke, Va., Metcalf and Sperry. Anacharis canadensis (Michx.) Babinet. Harold St. John, revising New England representatives of this group (Rhodora 22, pp. 17-29, Feb. 1920), applies the name Elodea occidentalis (Pursh) to the form occurring here and records a speci- men collected in the District of Columbia by Ward, June 11, 1882. Panicum dichotomiflorum Michx. M. L. Fernald (Rhodora 38, pp. 387-390, Nov. 1936) mentions 4 varieties of this species from the United States of which 2 are recorded from the District of Columbia. They have considerably over-lapping ranges, the typical variety occurring in purest form to the northward and westward, and the other, geniculatum (Wood) Fernald, to the south and east. (Suppl. 7, p. 47.) Panicum scoparium Lam. A. S. Hitchcock says, in a letter of March 15, 1930, that although following usage at the time, Scribner was in error in using this name, the grass he collected at Great Falls being that now called P. scribner- zanum Nash. Cyperus microdontus Torr. According to Hugh O’Neill (Rhodora 42, pp. 84-86, March, 1940) this plant should be known as Cyperus polystachyos Rottb. var. texensis (Torr.) Fern. He records a specimen from the District of Columbia, 1896, Steele. . Cyperus diandrus Torr. Hugh O'Neill, who has recently made a monographic study of the genus Cyperus, reports that all the material from the District of Columbia’ determined as C’. diandrus that he has seen represents C. rivularis Kunth. 150 Proceedings of the Biological Society of Washington. 95. 96. 107. 109. Eleocharis acuminata (Muhl.) Nees. This name is considered unidentifiable by H. K. Svenson (Rhodora 34, pp. 215-217, Nov. 1932) who uses for our plant the designation Eleocharis compressa Sull., citing specimens from Montgomery County, Md., and the District of Columbia. Eleocharis flaccida (Reichenb.) Urban. Specimens from Hunting Creek (S. F. Blake 11,086), referable to this species as treated in the 1919 Flora and collected at the only locality given for that species in the Flora, were identified as E. olivacea by H. K. Svenson, who states (Rhodora 31, p. 236, Nov. 1929) that he has seen no undoubted specimens of F. flaccida from north of Georgia. Carex. In Mackenzie’s treatment (N. A. Flora 18, 1931-35) of the genus, names different from those given in the 1919 Flora are used for the following species for which District of Columbia occurrence is cited: MaAckENzI& PAGE 1919 FLora NUMBER . radiata (Wahl.)

J. Hermann contributes the following remarks on two species of the preceding list: C. plana Mack. d Since intermediates between this and C’. muhlenbergi are frequent, I believe it is better kept as C. muhlenbergii var. enervis Boott. C. albicans Willd. H. K. Svenson has recently shown that this name is untenable (Rhodora 40, pp. 330-331, 1938). C. emmonsit Dewey, the term used for it in the 1919 Flora, seems to be the earliest available appel- ation. Carex angustior Mack. The basis of this record, both in the 1919 D. C. Flora and in N. A. Flora 18 : 118, is a collection in the District Herbarium by Standley (No. 11,751) from Paint Branch swamp which was so named by Mackenzie. The collection, however, represents a form of C. howez Mack, in which the perigynia are unusually narrow. C. angustior isa McAtee—S8th Supplement to Flora of D. C. and Vicinity. 151 109. 110. 118. 119. 120. 139. 140. 154. northern species, occurring south of Connecticut only in the moun- tains. F. J. Hermann. Carex projecta Mack. The only specimen in the District Herbarium under this name is a collection of C. scoparia Schkuhr. This is apparently the basis of the reports here and in N. A. Flora 28: 166. On account of its northern range, C’. projecta is not likely to occur in the District of Columbia region. F. J. Hermann. Carex gynandra Schwein. C. A. Weatherby (Rhodora 25, p. 18, Feb. 1923) treats this as a variety of C. criniia and records a specimen from Takoma Park, D. C., May 17, 1903, J. H. Painter. Juncus marginatus Rostk. The name Juncus coriaceus Mackenzie (Bul. Torrey Club, 56, pp. 27-28, Jan. 1929) applies to the plant that has been passing as J. setaceus rather than to J. marginatus. F. J. Hermann. See also Section I. Juncoides campestre bulbosum (A. Wood) Coville & Blake. Theo. Holm (Rhodora 28, pp. 134-138, Aug. 1926) considers Luzula multiflora (Erh.) Lej. as a species distinct from L. campestris DC, and says it is “very frequent in the vicinity of Washington, D. C.” Basing comment on his studies reported in Rhodora 40 : 83-86, 1938, F. J. Hermann says, “The commoner D. C. form is Luzula echinata (Small) Herman and the less frequent form is L. multiflora (Ehrh.) Lejeune, var. bulbosa (Wood) Hermann. Stenanthium robustum 8S. Wats. Thriving colony in a meadow at Merrifield, Va., Fairfax County. H. A. Allard, 1937. This form was recorded in Ward’s Flora 1881 and there is difference of opinion as to its validity (see Gray’s Manual, 7th Ed., 1908, p. 284). Quercus heterophylla Michx. This hybrid, ascribed to crosses of various species, is said by H. A. Allard (Bul. Torrey Bot. Club, 59 (5), May, 1932, p. 276), agreeing with D. T. MacDougal (Bot. Gaz. 43, 1907, pp. 45-58), to have the parentage phellos X maxima (i. e. rubra) not phellos X velutina as recorded in the 1919 Flora. Quercus ilicifolia Wang. The 1919 Flora notes “possibly not reaching our limits,’’ but the species occurs in sandy land between the Baltimore Boulevard and Little Paint Branch near Ulle’s Crossing, Md. Not far outside of our limits at Odenton, Md., it is common. W. L. McAtee. Silene caroliniana Walt. Robert T. Clausen (Rhodora 41, pp. 575-584, Dec. 1939) assembles with this form two other plants usually accepted as species and treats them as subspecies. The local representative, of which several specimens are cited, is S. c. pennsylvanica (Michx.) Clausen. . Hydrangea arborescens L.

C. region: the typical one ‘‘in silvis frequens prope Washington, D. C., July 15, 1888,” Th. Holm; and var. oblonga T. & G., District of Columbia, Herbarium of A. Gray. Aruncus vulgaris Raf. M. L. Fernald (Rhodora 38, p. 181, May, 1936) notes that Rafin- esque’s proposals for this genus were nomina nuda and recognizes A. alleghemensis Rydberg as the valid name for the eastern North American species. The name A. pubescens Rydb. is segregated in its application to ‘‘an interior variety,’ yet plants with ‘the lower leaf-surfaces soft-pubescent”’ are cited from Washington, D. C. (Steele et al) and other eastern localities. ‘The really distinctive character of the variety is more slender follicles.”’ In September, 1939, the same author (Rhodora 41, pp. 423-424) points out that Walter described the American plant in 1788. The name is, therefore, changed to Aruncus dioicus (Walt.) Fern. var. pubescens (Rydb.) Fern. Potentilla canadensis L. According to M. L. Fernald (Rhodora 33, pp. 180-191, Sept. 1931), usage of this name reverts to that of Ward (Flora 1881), its applica- tion being to the plant called P. pumila in the 1919 Flora. Fernald records the typical variety from Bladensburg, Md., and Takoma Park, D. C. 176. Potentilla simplex Michx. 195. 200. M. L. Fernald (Rhodora 33, pp. 180-191, Sept. 1931) returns to the usage of Ward (1881 Flora) in this case, this name replacing P. canadensis of the 1919 Flora.- However, the specimens cited from our region are of a glabrate variety for which the name calvescens is proposed. A specimen from Naucks, D. C., June 1, 1913, Steele, is cited. Acalypha gracilens A. Gray. According to C. A. Weatherby’s treatment (Rhodora 29, pp. 193- 204, Oct. 1927) of this group, 3 instead of the usual 2 species are recognized, of which digyneza Raf. is that listed as A. gracilens in the 1919 Flora. This latter species is not recorded from our region by Weatherby. His citations are: A. virginica, Cabin John, Md., Oct. 10, 1912, Maxon; and A. digyneia, Bethesda, Md., Sept. 10, 1899, Steele. According to a later revision by Weatherby (Rhodora 39 : 14-16, 1937), Acalypha virginica of his 1927 account becomes A. rhomboidea Raf. and A. digyneia becomes A. virginica L. (Supl. 8, p. 47.) Acer pseudo-platanus L. In September, 1930, E. S. Steele said in a letter ‘“‘my record [of this species] probably was a misdetermination of the common Norway maple, of which I found seedlings.”’ . Ascyrum hypericoides L. M.'L.

JOHNSON, Museum of Vertebrate Zoology, University of California. Chipmunks were well represented in the collection of mam- mals taken by the Alexander Nevada Expedition of 1909 in the Pine Forest Mountains of northern Humboldt County, Nevada. Lacking adequate material for comparison, Taylor (Univ. California Publ. Zool., 7 : 222, June 24, 1911) in his published report included the two species, Hutamias minimus and Hutamias amoenus of current nomenclature, under the name Eutamias pictus. Howell (North American Fauna, 52 : 65, Noy. 30, 1929) distinguished the two species in the mentioned collection and referred specimens of the species amoenus to the subspecies monoensis, which had been described by Grinnell and Storer (Univ. California Publ. Zool., 17:3, Aug. 28, 1916) from the Mono region of east-central California. The race monoensis was thus made to include populations from two areas separated by about 175 miles of desert not inhabited by Hu- tamias amoenus. This unusual distribution led us to examine the pertinent material, with the result that we found numerous differences, some of which were pointed out by Howell (loc. cit., p. 66), between specimens from the two areas. According to our interpretation, each of the two populations currently assigned to monoensis is a restricted and independently evolved race peripheral to the wide-ranging subspecies amoenus. For the more northern race we propose the name: Eutamias amoenus celeris, new subspecies. Type.—¥emale, adult in fresh summer pelage, skin and skull; no. 7950, Mus. Vert. Zool.; near head of Big Creek, 8000 ft., Pine Forest Mountains, 29—Proc. Brox. Soc. Wasu., Vou. 53, 1940. (155) c DFC 28 1940 Gee Sp 156 Proceedings of the Biological Society of Washington. Humboldt County, Nevada; July 21, 1909; collected by C. H. Richardson, Jr.; original no. 3198. Range.—Higher parts of the Pine Forest Mountains of een Hum- boldt County, Nevada. a Diagnosis.—Size small; color pale, particularly on edges and top of tail; skull narrow. Comparisons.—F rom monoensis, as known to us by topotypes and other specimens from the southern Sierra Nevada, celeris differs in: hind foot shorter, tail slightly shorter, top of head grayer, light facial and dorsal stripes clearer white, ochraceous color of sides more intense, top and edges of tail paler, feet paler, skull narrower. From the subspecies amoenus, celeris differs in paler color of the sides and otherwise in the same ways as from monoensis although in each instance to a greater degree. Remarks.—Individuals of this race average smaller even than monoensis, and these two races are the smallest and palest of the species. The pale coloration we interpret as a response to the arid conditions under which both subspecies live. Howell (op. cit., p. 66) referred one specimen from the Cottonwood Range [= Santa Rosa Mountains], the next range east of the Pine Forest Mountains, to Hutamzas amoenus monoensis. In response to our inquiry about this record, Dr. H. H. T. Jackson sent us for examination a skin and skull, U. S. Nat. Mus., Biol. Surv. Coll., catalogue no. 80755, collected on September 17, 1896, by Clark P. Streator in the “Cottonwood Range.” The label has stamped on it “‘Hutamias a. monoensis”’ but the specimen proves to be Hutamias minimus scrutator. Thus if, as we suppose, this is the specimen identified by Howell as #. a. monoensis, the reported occur- rence of the species Hutamias amoenus in the Santa Rosa Mountains is based on a misidentification. Measurements.—Average and extreme measurements of 5 adult males and 3 adult females are: Total length, o 190 (187-194), 2 193 (189-195); length of tail, 83 (78-86), 84 (82-85); length of hind foot, 31.2 (80-82), 29.3 (29-30); condylobasal length of skull, 29.0 (28.6-29.3), 29.6 (28.7- 29.2); greatest length, 32.5 (31.8-32.7), 32.2 (31.9-32.5) ; zygomatic breadth, 17.5 (17.38-17.8), 17.7 (17.6-17.8); cranial breadth, 15.0 (14.9-15.2), 15.2 (15.0-15.3); interorbital breadth, 7.5 (7.3-7.7), 7.3 (7.2-7.4); length of nasals, 9.6 (9.49.9), 9.9 (9.89.9).

RTT, OG 79 Vol. 53, pp. 157-158 December 19, 1940 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON A NEW COTTON RAT (SIGMODON) FROM ARIZONA AND NEW MEXICO. BY SETH B. BENSON, Museum of Vertebrate Zoology, University of California. Specimens of cotton rats obtained in March, 1940, in the Huachuca Mountains of Arizona make possible the recognition of an heretofore undescribed race of Sigmodon ochrognathus Bailey ranging in southeastern Arizona and southwestern New Mexico. Sigmodon ochrognathus montanus, new subspecies. Type.—Male adult, skin and skull, no. 92287 Mus. Vert. Zool., collected at Peterson’s Ranch (also called Sylvania), 6100 ft., Huachuca Mountains, 2 miles north of Sunnyside, Cochise County, Arizona, on March 15, 1940, by Seth B. Benson, original number 6649. Distribution.—Known only from the Huachuca Mountains in Arizona and the Animas Valley in New Mexico, but probably also occurring in suitable habitats in the adjacent area. Diagnosts.—A race of Sigmodon ochrognathus characterized by a sharply bicolored tail, hairs on inside of pinnae of ears tipped with yellowish, yellowish feet, small audital bullae, largeears. InS. 0. ochrognathus the tail is only indistinctly bicolor, the hairs on the pinnae of the ears and on the feet are grayish, and the audital bullae are more inflated, the ears slightly smaller. Color (Capitalized color terms after Ridgway, Color Standards and Color Nomenclature, 1912).—Dorsal surface grizzled gray tinged with yellowish ranging from Pale Ochraceous-Bufi mid-dorsally to Ochraceous-Buff on flanks and rump. Belly hairs white-tipped. Basal portions of hairs Blackish Plumbeous. Nose and distinct ring around eyes Light Ochraceous- Buff. Tail sharply bicolor for most of its length, tipped with black. Hairs on dorsal surface of tail black, on ventral surface Light Ochraceous-Buff. Dorsal stripe on tail strongly accentuated by dark skin pigments. Hairs on inside of ears black, tipped with Light Ochraceous-Buff. Ear tufts Light Ochraceous-Buff. Feet tinged with Light Ochraceous-Buff. The color in S. 0. montanus is richer than in S. 0. ochrognathus and is most evident on the ears and feet. - 30—Proc. Bron. Soc. Wasx., Vou. 53, 1940. ~ (187) 158 Proceedings of the Biological Society of Washington. Measurements.—Two young adult males (type and a paratype, respec- tively): Total length, 233, 236; tail, 100, 106; hind foot, 28, 28; ear from notch, 18, 18; ear from crown, 14, 14; weight in grams, 73.1, 76.3; basal length, 27.8, 27.0; nasals, 11.3, 11.4; zygomatic breadth, 18.7, 17.7; mastoid breadth, 13.0, 13.0; alveolar length of upper molar series, 5.8, 5.9. Specimens ecamined.—Total number, 7, as follows: Huachuca Mountains, Cochise County, Arizona: Peterson’s Ranch, 6100 feet, 2 miles north of Sunnyside, 5; Head of Miller Canyon, 8400 feet, 1. Animas Valley Hidalgo County, New Mexico: 4 miles northwest of San Luis Pass, 5200 feet, 1. Remarks.—F¥our of the specimens from the Huachuca Mountains and one from Animas Valley were tentatively referred to Sigmodon hispidus cienegae by Hall and Davis (Proc. Biol. Soc. Washington, vol. 47, February 9, 1934, p. 54). They pointed out the differences in color between the young speci- mens and S. h. cienegae, but did not name the variant because the immatur- ity of the specimens made it possible that the observed characters were not significant from a systematic standpoint. Actually, the young specimens are specifically distinct from S. hispidus. I visited the Huachuca Moun- tains to obtain adult specimens of the yellow-nosed cotton rats, and the Chisos Mountains of Texas for topotypes of Szgmodon ochrognathus, which had been described as a yellow-nosed species, to compare with the Arizona specimens. In spite of the strong geographic isolation between the two populations, and the differences in characters noted above, the populations are so similar in most features that it seems best to consider netaee only subspecifically distinct. Me The species S. ochrognathus has been recorded from only a few localities. Bailey (Proc. Biol. Soc. Washington, vol. 15, June 2, 1902, p. 115) recorded it from the Chisos Mountains, Texas, and from near Parral, Chihuahua. Blair (Mise. Publ., Mus. Zool., Univ. Michigan, no. 46, June 28, 1940, p. 32) recorded the species from the Davis Mountains of Texas. To my knowledge these are the only records for the species. Therefore, the records for New Mexico and Arizona are new and indicate a much more extensive distribution for this species than was formerly known. INDEX. New names are printed in heavy type.
