Characters. — Size comparatively large, the height at the shoulder 

 varying from about 3 feet 2 inches to 3 feet 6 inches in the larger races. 

 Face-glands very small, and the pits in the skull for their reception corre- 

 spondingly reduced in size. Horns of adult male markedly triangular, with 

 the transverse wrinkles much less developed and the longitudinal stris 

 distinctly more apparent than in any of the species hitherto mentioned ; 

 the outer front angle markedly prominent, but the inner one partially 

 rounded off; the curvature forming a more or less close spiral, but little 

 if at all exceeding one complete circle. General colour ot upper-parts 

 varying from white or pale tawny to dark grayish-brown, frequently with 

 a darker streak along the middle line of the back ; a white disk ot variable 

 size on the buttocks, which is always divided in the middle line by a dark 

 streak connecting the brown of the back with the dark upper surface of the 

 tail ; flanks and front surfaces of the legs darker than the back ; more or 

 less of the under-parts, as well as a considerable portion or the whole ot 

 the posterior surfaces of the legs, together with a variable proportion 

 ot their inner sides, white ; outer aspect of thighs always dark coloured 

 like the back.
