Hoofs large, cylindrical, blunt, in shape and position quite different to 
those of other Antelopes. The animal in life walks upon what is normally 
the pointed tip of the hoofs, so that the hoof stands up vertically, only its 
blunted end resting on the ground. Accessory hoofs present. Hairs of coat 
thick, pithy, somewhat similar in texture to those of the Musk-Deer. Tail 
a mere stump, scarcely projecting beyond the fur. 
Skull peculiarly short and broad, stoutly built. Anteorbital fosse large. 
Horns directed nearly vertically; slightly curved forwards; their basal 
third ringed. 
Distribution. Eastern and Southern Africa, from Abyssinia to the Cape. 
Only one species is known.
