THE LARGER EAST AFRICAN ANTELOPES 



defassa. The white eye-stripe is clear and well defined, 

 but does not extend farther backward than over the an- 

 terior third of the eye. Above the black face the forehead 

 is bright rufous, somewhat mixed with black. The sides 

 of the face behind the lateral extension of the black have 

 the same color as the forehead, except that the region from 

 below the eye to the root of the ear is paler, huffish brown, 

 shading into whitish at the ear. The sides and the under 

 parts of the lower jaw behind the clear white chin are 

 dark brown, somewhat mixed with hoary white from the 

 basal parts of the hair. The back of the ears is rufous, 

 but with broad white areas on either side ; the tip is black 

 and the inside white. 



" The upper side of the neck is rufous with black tips 

 to the hairs, but the sides and the lower parts of the neck 

 behind the white throat patch is of a mixed grayish brown 

 color, produced by the hairs having their distal parts black- 

 ish and their basal parts light gray and partly rufous. The 

 color of the body is also mixed in a peculiar manner. It 

 is dark brown, in some light, almost blackish brown, but 

 to a certain degree mixed with red. This is effected by 

 the hairs having long black tips and rufous bases, and be- 

 sides some scattered hairs are (basally or wholly) whitish. 

 Toward the root of the tail and at the borders of the white 

 rump-patch the rufous color is more dominating, but other- 

 wise the whole animal is much darker than the rufous 

 brown typical Cobus defassa. The hairs are rather short, 

 only measuring about 2 cm. on the back and sides. 



" The under parts are dark brownish gray, the distal 

 parts of the hairs being dark smoky brown, and the basal 

 parts hoary gray. The posterior of the belly, from the 

 inguinal tract to around the naval, is whitish with long 

 hairs. At the prepuce a tuft of brown hairs is placed. The 

 legs and feet are black with a brownish shade in front. A
