The [ox's] horns are of nearly equal size in both sexes, are placed on or near the vertex of the skull, and may be either rounded or angulated, while their direction is more or less outwards, with an upward direction near the tips, and conspicuous knobs or ridges are never developed on their surface.
Except in the bongo and elands, horns are present only in the males, and these are angulated and generally spirally twisted, and without rings.
The long face, high crest for the horns, which are ringed, lyrate and more or less strongly angulated, and the moderately long tail, are the distinctive features of the hartebeests.
In the males the horns are generally angulated, and marked by fine transverse wrinkles; their colour being greenish or brownish.
The forelegs should be straight and strong and the hindquarters moderately angulated with well turned stifles.
