Vernacular Name:—Coquetoon on the Gambia (Whitfield).
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; those of male short, conical, pointed (but no adult wild specimen is available for description); those of female rudimentary, mere low rounded knobs, hardly projecting above the skin of the head.
Skull with a long and slender muzzle. Anteorbital fossæ remarkably deep, more so than in any other species. Mesial palatal notch about a quarter of an inch anterior to the lateral ones.
Dimensions:—♂. Height at withers 14 inches, ear 2·3, hind foot 7.
