BANDED DUIKER 159 



nape, dorsal patch, and feet of the type race gives place to slaty grey 

 in the Welle race. In both races the chin and the inner sides of the 

 thighs are white. 



THE BANDED DUIKER 



( CepJialopJuis doricE) 



Very few words will suffice for this striking species, which is a 

 native of Liberia (where it is commonly known as the " mountain 

 deer "), distinguished from all its kin by the pale rufous back being 

 marked by a number of broad black transverse stripes. In height it 

 stands about 16 inches. The zebra-antelope, as the species is often 

 called, may be regarded as an aberrant off-shoot from the group of 

 red duikers. 



WALKER'S DUIKER 



{CepJialoplius ivalkeri) 



With this species, which was named by Mr. O. Thomas in the 

 Zoological Society's Proceedings for 1906, on the evidence of a female 

 specimen killed on the Tachila river, about twenty-five miles from 

 Blantyre, Nyasaland, we come to the first of the dusky or blackish 

 duikers, which are evidently specialised derivatives from the more 

 primitive red group. It is a very dark-coloured, medium-sized species, 

 about equal in size to CephalopJnis leticogaster. 



The general body-colour is dark greyish brown, approaching sepia ; 

 the hairs, except on the back, where they are nearly black, being speckled 

 with huffish ; while on the under-parts and inner sides of the limbs 

 the colour lightens to the tint known as hair-brown. From the muzzle 

 to between the ears the front of the face is black, as is the tuft ; but 

 the chin and cheeks are pale fawn, with a line of more distinct buff near 

 the black above the eyes ; the backs of the large ears are grizzled 

 brown or blackish. A black line along the nape connects the black 

 face-patch with that of the loins. The limbs are wholly dark, with the 

 lower portion nearly black ; but there seems to be some white on the 

 tail. 



This species may prove to be allied to C. nigcr ; the dark forehead 

 distinguishes it from C. leucoprosopus, in which that part is chestnut.
