CEPHALOPHUS COXI. 119 



animal is of about the size of our adult Congo-specimen 

 of C. silvicultor (N. L. M. Vol. XXII, p.p. 179—187), there- 

 fore a trifle smaller than our Liberia-female; horns shorter 

 and hoofs more slender than in C. silvicultor ; color quite 

 different from and triangle on back larger than in the 

 latter species ; buttocks colored like triangle and not like 

 sides of the animal as in C. silvicultor ; triangle not sepa- 

 rated from the rump-disk by a black band as in that species. 



Description of the type-specimen, an adult male: the 

 figure in the Book of Antelopes, Plate XIV, fig. 2, may 

 give a fairly impression as to the general color and its 

 distribution, so that I here have to add mere small pecu- 

 liarities not so easily to reproduce in such a small drawing. 

 In C. silvicultor is a light colored streak above each eye, 

 in C. Coxi not ; between the horns is a very good developed 

 crest of very long bright rufous hairs; basal part of horns 

 anteriorly concealed by the same kind of elongated rufous 

 hairs. Whitish triangle beginning on the back above the 

 fore-legs, ending a good deal nearer to the tail than in C, 

 silvicultor ; the disk is much less developed than in silvicultor 

 and clad with black hairs; buttocks largely adorned with 

 the same kind of beautiful whitish hairs as the triangle; 

 upper part of tail for its basal part with brownish rufous 

 hairs, for the rest whitish ; distal part of tail and tuft with 

 a mixtum of elongated black and rufous black hairs. 



Horns shaped like in C. silvicultor and for their basal 

 half more strongly roughened than in that species, however 

 shorter as they measure 104 mm. only. Hoofs more slender 

 than in silvicultor and relatively as well as absolutely larger 

 and more elongated than in that species. I got the animal 

 stuffed with the skull in it; I do not like to run risk of 

 destroying the skin by removing the skull.
