PENRICE’'S WATERBUCK. 
By THE HON. WALTER ROTHSCHILD. 
[From Novitates Zoologice, vol. v. February 1895. | 
Cobus penricei sp. nov. 
At once distinguishable from its allies, Codus ellipsiprymnus, C. 
defassa,* and C. unctuosus, by its intensely blackish colour. The muzzle 
is whitish, the face black, interspersed with rufous hairs between the 
horns. The usual white stripe passes from in front and over the eye to 
the base of the horns. Ears—outside, rufous brown, with blackish tips 
and edges ; inside, white. Sides of face, neck, and body deep brownish- 
black, plentifully interspersed with reddish-brown hairs, all of them 
being white at base, which gives the animal a colour that in a horse is 
called “blue-roan.” This latter colour is more conspicuous on the 
belly, where the hairs are longer, but much less on the legs and hind 
half of the back, which parts are almost uniform brownish-black. ‘Tail 
black above, white below. There is a large patch of white on the 
upper throat. 
The hornless femave is similar in colour, but the ears are less rufous 
and more brown. 
The horns are much shorter than those of its three allies, and 
* The name must be spelt defassA, and not defassus, as defassa is a native name. It is, how- 
ever, spelt defassus in several books, and also on the plate, by mistake.
