Cuv. An. K. iv. p. 268 (1827). Cephalophus bicolor, Gray, T?.Z.S. 1862, p. 263,pl.xxxiv. (animal). Size and characters of horns as in C. melanorheus. Colour as in C. maxwelli, except that the legs from the elbows and knees downwards are bright rufous. Dimensions.- $ . Height at withers 320, ear 40, hind foot 154. Skull-basal length 109 ; greatest breadth 57; anterior edge of orbit to gnathion 61 ; nasals, length 401, breadth 24*3 ; muzzle 38 ; upper molar series 34\5. Hab. South-east Africa. Umgozy Forest, Zululaud [Dunn (Brit. Mus.)]; Eland's Post [Atmore (Brit. Mus.)]; Galgebosch'2, Uitenhage [Dr. Burchell (Brit. Mus.)]. This and the last species, and, if the female is not always hornless, C. maxwelli also, might be considered to be merely geographical races of one single species. To settle the question, however, we must wait until the opening up of the interior of Africa shows what are the characters of any representative forms that may be found there. 16. CEPHALOLOPHUS CORONATUS, Gray. C. coronatus, Gray, Ann. Mag. N. H. (1) x. p. 266 (1842). Size probably, in adult animals, about equal to that of C. abyssin-icus ; form slender. Colour uniformly light yellow all over, except a small streak on the nasal region, the tip of the tail, and the metacarpus and metatarsus, all of which are black. The yellow hairs of the body finely grizzled with black. Horns, skull, and teeth of adult not yet' known. In the type skull, that of a half-grown animal, the anteorbital fossae are of moderate depth, and the mesial notch on the palate is about 10 m m . in advance of the lateral ones. Dimensions of type, immature 3 •-Height at withers 410; ear 75 ; hind foot 206. Hab. W . Africa. Gambia [Whitfield (Brit. Mus.)]. Of this pretty species there are only in the Museum immature and young specimens, and from this material I am unable to come to a definite conclusion as to its relationship. In its general appearance, however, it has a certain amount of resemblance to the Duiker group, of which it may be the West-African representative, and 1 have therefore in the synopsis included it provisionally in the same section as C. grimmii and abyssinicus. I should, however, feel no surprise if the examination of adult skulls and horns proves this conclusion to be wrong. 17. CEPHALOLOPHUS ABYSSINICUS, sp. n. Size about one-third smaller than that of C. grimmii. Ears elongate, 1 From another speeimen. a Collected in February, 1814. Type of A. ccerulea. |
