Mr. J. E. Gray on some Species of Cephalophus. 167 



thigh white ; broad streak over each eye to the base of the horns 

 yellowish white ; feet and end of nose rather darker ; fur rather 

 rigid; hair uniform. 



Inhab. W. Africa. 



This species is known from C. monticola by being larger, by the 

 white of the eye streak and the white on the front of the thigh 

 and chest and the rigidity of the hair. 



There is an adult male and female of this species in the British 

 Museum ; the male is bright sooty brown, darker near the rump ; 

 the female is nearly uniform pale gray brown. It is well-figured 

 by M. F. Cuvier. 



11. The Blau Boc or Cape Guevei, Cephalophus monticola.

 mea, Licht. S. t. 16, Desm., Sund. 



Gray brown ; streak over the eyes, legs and outer part of thighs 

 rufous ; feet gray brown ; chin, chest, abdomen, and under side 

 of tail and inside of ears white ; fur soft gray with intermixed 

 rather rigid black hairs. 



Inhab. South Africa. 



The colours vary in intensity in a female in the British Mu- 

 seum j the rufous colour of the thigh and the white of the breast 

 are more distinct than in the male, but this depends on the sea- 

 son when they were killed. 



A very young fawn, which was brought home from the Cape 

 by M. Verreaux, is darker, and the reddish tint extends over the 

 head and the whole body. 



12. The Black-rumped Guevei, Cephalophus melanorheus. Ce- 

 phalophus Philantomba, Gray, Cat. Mam. B. N. 163. 



Gray brown ; throat and sides paler ; rump and upper part of 

 tail black ; chin, chest, abdomen, back and front edge of thighs 

 and under part of tail white ; narrow streak over the eyes whitish ; 

 feet like the back ; fur soft, pale gray, with intermixed rather 

 rigid black hairs. 



Inhab. Fernando Po. J. Thompson, Esq. 



There are two specimens of this species in the British Mu- 

 seum ; they are easily known by the black mark on the rump ; 

 they are coloured like the Guevei from W. Africa, but smaller, 

 and have the soft fur and interspersed black hair of the Cape 

 Guevei, C. monticola. 



13. The Grisled Guevei, Cephalophus punctulatus. A. Philan- 

 tomba, H. Smith, G. A. K. ? 



Dark fulvous brown ; sides and legs rather paler ; narrow streak
