Show 18G6.] DR. J. E. GRAY ON A N E W SPECIES OF NASUA. 169 CERCOPITHECUS ERYTHROGASTER. (PI. XVI.) Fur blackish, minutely punctated with yellow; the yellow dots on the crown of the head more abundant, and nearly absent on the hands and wrist; outside of the hind legs and thigh grey, punctured with blackish ; face, moustache, and the frontal band, which is continued across the temple to the ears, black; round spot on each cheek pale yellow ; whiskers, beard, throat, and sides of neck white ; front of thighs and under surface of the tail greyish white; chest and belly red brown. Hab. West Africa. There is a young female of the species in the Gardens of the Society. The red bell}' and chest, the white beard and whiskers, and the black frontal band at once distinguish this species. The yellow crown is very peculiar; it is rather extended backward towards the nape, and separated from the fur of the back by an undefined blackish crescentiform band. 2. Notice of a N e w Species of Nasua. By Dr. J. E . G K A Y , F.R.S., V.P.Z.S., F.L.S., &c. (Plate XVII.) Mr. Whiteley, of Woolwich, has lately brought to the British Museum the skin of a Nasua, which differs considerably from any skin of the genus that I have hitherto seen, in having a distinct broad black streak along the hinder part of the back to the base of the tail. I believe that it may belong to a distinct species ; at any rate it presents a variation in colouring of this variable genus that I have not seen described. The fur is reddish brown. There are two specimens which agree with it in general colouring and kind of fur in the British Museum collection, but they are without the dorsal streak. NASUA DORSALIS. (PI. XVII.) Fur red brown ; underfur dull brown, longer hairs thin, pale, with thick red-brown tips; chin, throat, and chest whitish; face pale, blackish-grizzled; feet and broad streak on hinder half of the back black ; tail blackish, with irregular interrupted grey rings. The skull is imperfect, the face with the teeth only having been preserved. The face resembles that of the skull of Nasua narica in the Museum Collection, no. 225 a (the measurement of which is given in m y paper on Ursidar, P. Z. S. 1864, p. 703), in having a long narrow compressed nose and elongated canine teeth. It differs from the skull of N. narica in the upper jaw being rather shorter from the middle of the cutting-teeth to the end of the last molar, and rather wide at the hinder part at the sides of the hinder molars, and rather narrower at the end of the nose. The upper cutting-teeth are narrower; that is to say, the space occupied by the series P R O C ZOOL, Soc-1866, No. XII. |
