Adult male, at the withers, about five feet ten inches or, according to some writers, sometimes considerably over six feet in height. Body, head, legs, and neck of a tolerably uniform tawny colour, but often assuming a slaty-grey hue in old age, owing to the rubbing off of the hair and the consequent exposure of the skin beneath. Frontal mat of hairs varying from yellowish brown to black, apparently becoming darker with age; nose generally ashy black; lips and chin white. Ears narrow and pointed, of a uniform greyish-fawn tint, with at most a small black patch on the lower rim in front. A narrow black spinal stripe, extending from the withers to the base of the tail. Tail-tuft and tuft of hair on the dewlap black. Legs like the body, but, on the inner side, sometimes with a greyish patch above the knee on the pasterns; back of the pasterns and narrow rim above the hoofs and false hoofs black. Horns about 30 inches or more in length. _Female_ like the male in colouring, but smaller and more slightly built; the horns thinner, less strongly crested, and less twisted, but usually longer and (exceptionally) reaching a length of 34 inches. The subspecies _T. o. livingstonii_ is generally similar to the typical form, but has the coat of a ruddier fawn-colour, and is ornamented on each side of the body and hind-quarters with from about eight to eleven narrow vertical white stripes: these are strong upon the flanks and faint upon the haunches; they commence from the black spinal stripe and gradually fade away upon the belly and lower part of the thighs. In the typical form, moreover, there is a large black patch on the inner and posterior side of the fore leg above the knee. Horns reaching about 32 inches. _Female_ differing from the male in the same respects as in _T. o. typicus_. The subspecies _T. o. gigas_ is based on a pair of horns obtained by Heuglin on the White Nile, and distinguished by their large size, great length (35 inches), and strong corrugations. From Schweinfurth’s observations we learn that this form carries well-marked body-stripes throughout life, sometimes 15 in number. In these two respects it would seem to approach _Taurotragus derbianus_, but Schweinfurth says nothing about the black neck of the last species. _Hab._ South Africa, from the Cape Colony (where it is now extinct) to Angola on the west and to the Transvaal and Mozambique on the east, and thence up to the Zambesi; at its northern limits passing into the striped form (_T. o. livingstonii_), which extends throughout Eastern Africa up to and rather beyond Mount Kenia; also found on the White Nile and in the adjacent districts (_T. o. gigas_). At the close of the long series of Antelopes we arrive at the largest and finest form of the whole group, and one, moreover, that might well become of great economical importance to mankind, if proper measures were taken for its acclimatization.
