Back with a broad black dorsal band commencing behind the withers, broadening posteriorly, and involving the whole of the hams and backs of the hind legs down to the heels, and also the tail, with the exception of the extreme tip below, where the hairs are white-tipped. On the sides of the thighs, edging the black, the general body-colour becomes rich rufous. Horns short, directed backwards, lying below the level of the nasal profile. Dimensions.- $ . " Total length to tip of tail 1170 m m . " ; " tail 210;" "ear 70." Skull (taken from figure, and therefore only approximate):- Basal length 164; anterior edge of orbit to gnathion (more or less decreased by perspective) 98 ; nasals, length 74 ; length of molar series (milk-teeth still in place) 60. " Length of skull" (fide Peters) 180 (the greatest length of the drawing is 184 mm.). Hab. Gaboon [Buchholz (Berl. Mus.).]. The description is compiled from Dr. Peters's description and figure of this striking species, of which I have never seen a specimen. 10. CEPHALOLOPHUS RUFILATUS, Gray, Ann. Mag. N. H. (1) xviii. p. 166 (1846). Size small; form slender. General colour partly bright yellowish rufous, and partly a peculiar bluish grey, the former colour covering the sides of the face, the whole of the neck, the shoulders, flanks, rump, and belly, while the latter prevails on the middle line of the nose, on the forehead, occiput, back of ears, centre of back from withers to rump, and all four limbs, from the elbows and middles of lower legs downwards. Crest long, blackish. Tail rufous above basally, black terminally. Horns placed in the same line as the nasal profile:- $. Short, conical, pointed (but no adult wild specimen available for description). $. Rudimentary, mere low rounded knobs, hardly projecting above the skin of the head. Skull with a long and slender muzzle. Anteorbital fossae remarkably deep, more so than in any other species, their bottoms within from 5 to 10 millim. of each other. Mesial palatal notch some distance (5 to 7 m m . ) anterior to the lateral ones. Dimensions.- d1 • Height at withers 360 ; ear 58; hind foot 179. Skull (?)-basal length 132; greatest breadth 66; orbit to gnathion 73 ; nasals, length 53, breadth 25 ; muzzle 45; upper molar series 49. Hab. W . Africa. Gambia [Whitfield (Brit. Mus.)]. A young skull from the Niger [Baikie (Brit. Mus.)] has also, and probably correctly, been referred to this species. It is difficult to say to which of the other species this peculiar little animal is most allied, especially as the absence of wild-killed male specimens renders me unable to describe the fully developed |
