ISO ANTELOPES 



duikers afford good sport. In sunlight their bright colour renders 

 them conspicuous, although in shade they are stated to be almost 

 invisible. They are difficult to drive out of covert with dogs, but when 

 in the open are easily caught. Lesser red buck is a common name 

 in Natal for this duiker. 



ITURI RED DUIKER 



( Cephalophns centralis) 



The Ituri Forest of East Central Africa is inhabited by a red 

 duiker closely approaching the typical CcpJialopJius natalensis, but 

 distinguished by the following features : — 



The more sombre colour of the feet, the exclusively red hue of the 

 crest on the vertex of the head, which has no mixture of black hairs, 

 the brighter tint of the forehead, and the somewhat superior bodily 

 height. 



This species, or race (and it is almost certainly the latter), was 

 described and named by Baron Maurice de Rothschild and Mr. H. 

 Neuville in the Coviptes Rendus of the Paris Academy of Sciences for 

 1907. 



THE BLACK-FACED DUIKER 



{CephalopJius ^tigrifrons) 



Ngolo, West Africa 



(Plate vi, fig. 4) 



This is a medium-sized member of the red group distinguished 

 from natalensis by the presence of black on the face and limbs. 

 Although discovered by Paul du Chaillu so long ago as 1865, it was 

 not named till many years later, by Dr. J. E. Gray of the British 

 Museum. 



In height it stands about 18 or 19 inches at the withers. The 

 general colour is deep chestnut, scarcely paler below than above ; but 

 the crest and middle line of the face are black, thus forming a striking 

 contrast with the rufous eyebrow-streaks ; the nape is also browner, 

 and the legs from the knees and hocks downwards are blackish, as is 

 also the tail, except for the white hairs in its terminal tuft. The horns,
