Fur close and uniform, not intermixed with long black piles; long hairs of back about 33-35 mm. in length. General colour above clear grey suffused with the buffy of the underfur, the net result being nearest to Ridgway's " smoke-grey." Individually the longer hairs are light for their basal and black for their terminal halves, with a white subterminal ring about a quarter of an inch from their tip. Underfur brownish plumbeous basally, buffy clay-colour terminally. Under surface little paler, dull brownish, lighter in the axilla? and groins. Muzzle and chin blackish. Crown like back, but the light ends to the underfur almost obsolete. Back of ears brown, grizzled with clay-colour; longer hairs of inner surface creamy; a large postauricular patch yellowish clay-colour. Forearms and thighs like body ; hands and feet, both above and below, blackish brown. Tail brownish grey, broadly washed with black at the end and over the caudal gland. Skull, as compared with that of C. vetulus, markedly larger throughout; interorbital region longer and narrower, the part behind the postorbital processes specially lengthened ; frontals smooth and swollen ; palatal foramina very long; palate ending opposite to middle of m.2; mesopterygoid fossa long, the distance from the hinder edge of the palate to the concavity below the hamular processes 22 mm. ; front edge of prsesphenoid 6 mm. behind the palatal edge. Penis-bone of the usual canine canoe-shape, but much less strongly keeled than in the one example of C. vetulus available. Teeth of the general type of those of C. vetulus ; p.4 short and rounded ; a supplementary and probably abnormal m.3 present on each side, longer on the left than on the right. Dimensions of the type, measured in the flesh :- Head and body 650 mm.; tail 310; hind foot (s. u.) 130; ear 76. |
