Species of Bush-hick. 43 



more abundant and form the indistinct streak down the back 

 of the neck and front part of the back ; but in the latter part 

 they are more or less spread over the shoulders so as not to 

 form any regular dorsal band ; the black hairs are abundant 

 on the front part of the fore legs ; fore legs from the knees to 

 the hoofs and the hind feet blackish ; underside of the head 

 rather paler; chest blackish, hinder part of the belly and 

 inner side of the thighs white ; tail dark brown, white on 

 the underside. Hoofs elongate. 



Hab. West Africa, Gaboon {Du Chaillu). 



Differs from C. dorsalis in the softness of the fur, in the 

 underside of the head being bay and not whitish, in the hind 

 legs being brown, and in the hocks and feet to the upper 

 hinder hoofs only being black. In many respects it is like 

 C. nigrifrons ; but the fur is softer and longer and much paler. 



2. Cephalophus leucogaster. 



Fur bay, darker in the middle, with a broad black unde- 

 fined dorsal streak, which is broader in the middle and nar- 

 rower and more defined on the rump ; crown darker blackish 

 brown, paler-grizzled ; underside of the head, middle line of 

 the throat, the chest, belly, and inner side of the limbs white. 

 Tail rather bushy, with intermixed black and white long 

 hairs. 



Hab. West Africa, Gaboon {Du Chaillu). 



In Cephalophus badius the underside of the body is rather 

 paler bay ; the chest is black, which extends some way down 

 the belly in a narrow line ; the underside of the head is paler 

 whitish, the hinder part of the belly and inner side of the 

 thighs whitish. 



The Cephalophi, with conical, short, more or less re- 

 cumbent horns and separate nasals, may be divided into 

 groups according to the bones of their skulls.
