Typical locality Gabun. 



A medium-sized species, standing about 18 or 19 inches 

 at shoulder, distinguished from C. natalensis by a blackish 

 blaze on the face widest on the forehead and the dark 

 shanks and feet. It is further distinguished by the greater 

 uniformity of colouring, which is scarcely paler below than 

 above, and by the absence of pale bay on cheeks, sides of 

 neck, and throat, as well as of a white chin. 



General colour deep chestnut, scarcely paler below than 

 above, but head-crest and middle line of face blackish, and 

 contrasting strongly with rufous eyebrow-streak ; nape 

 rather browner ; limbs from knees and hocks downwards, 

 and tail, except for some white hairs in terminal tuft, 

 blackish. Horns short, somewhat expanded at base; skull 

 with convex frontal region ; hoofs relatively long. Basal 

 length of skull 6J, maximum breadth 3|- inches. 



The range extends along the west coast from the Gabun 

 to the Cameruns, and to Stanley Falls on the Upper Congo.
