_Adult male._ Height at withers about 50–52 inches. General colour of body varying from reddish to pale slaty bluish grey, the latter especially prevalent in older animals, and perhaps due, in part, to the scantiness of the hair revealing the tint of the skin. Neck brown on each side at its base and darker than the shoulders, becoming paler towards its anterior extremity. Head darker fawn than the anterior end of the neck, whitish around the eye, a white bar running inwards from the corner of each eye and forming an incomplete v-shaped mark on the nose; two or three white cheek-spots; edge of the upper lip and chin white, the white of the chin extending back on to the fore part of the inter-ramal area. From the middle of this area back to the hinder end of the throat extends a thickish mane of white and blackish-brown hairs; no white patches on the throat. There is also a dorsal mane passing from the occiput, backwards along the nape, over the withers and down the spine to the root of the tail; the mane brown on the neck and shoulders, white along the back. Sides of the body and hind-quarters marked with white stripes, which vary in number from about four in the northern forms to about nine or ten in the southern. Tail white below, black at the tip. Belly greyish, blacker in the middle. Fore legs of a rich fawn down the front, whitish at the base on inner side and behind the knee, also on the inner and posterior side of the cannon-bone, a pale blackish-brown patch above the knee on the inner side; fetlocks and pasterns also rich fawn, black behind; the white pastern-spots only just traceable. Hind leg coloured like the fore leg; inner side of the thigh at the base and anterior side down to the hock white, the white fading away between the hock and the pastern. Horns with bold and open spiral curvature, measuring about 40 inches or more in a straight line, and an additional 12 inches or so round the curve; distance between the tips varying, irrespective of the length, from about 24 to nearly 40 inches. The skull of an adult gives the following measurements:—Basal length 15 inches, orbit to muzzle 9, greatest width 6·33. _Female._ Generally similar to the male, but hornless and smaller and slighter; similarly marked with white, but the ground-colour of the body of a tolerably uniform fawn, becoming darker above. _Young_ redder in colour than the adult and strongly marked with white. _Hab._ Africa south of the Zambesi, extending on the west into Angola, and on the east throughout East Africa up to Abyssinia, mostly in the higher districts.
