1892.] OF THE GENUS CEPHALOLOPHUS. 427 



15. Cephalolophus monticola, Thunb. 



Antilope monticola, Thunb. K. Vet.-Ak. Hand], xxxii. p. 93 



(1811). 



Antilope {Cephalophus) ccerula, Ham. Smith, Gnff. Cuv. Au. K. 



iv. p. 268 (1827). 



Cephalophus bicolor, Gray, P.Z. S. 1862, p. 263, pi. xxxiv. (animal). 



Size and characters of horns as in 0. melanorheus. Colour as in 

 G. maxwelli, except that the legs from the elbows and knees down- 

 wards are bright rufous. 



Dimensions. — $ . Height at withers 320, ear 40, hind foot 154. 



Skull — basal length 109 ; greatest breadth 57 ; anterior edge of 

 orhit to gnathion 61 ; nasals, length 40\ breadth 24*3 ; muzzle 38 ; 

 upper molar series 34'5. 



Hab. South-east Africa. Umgozy Forest, Zululand [Bunn (Brit. 

 Mus.)]; Eland's Post \^Atm,oi'e (Brit. Mus.)]; Galgebosch", Uitenhage 

 IDr. Burchell (Brit. iMus.)]. 



This and the last species, and, if the female is not always hornless, 

 C. maxwelli also, might be considered to be merely geographical 

 races of one single species. To settle the question, however, we must 

 wait until the opening up of the interior of Africa shows what are 

 the characters of any representative forms that may be found there. 



16. Cephalolophus coronatus, Gray. 



C. coronatus. Gray, Ann. Mag. N. H. (1) x. p. 266 (1842). 



Size probably, in adult animals, about equal to that of C. abyssin- 

 icus ; form slender. Colour uniformly light yellow all over, except 

 a small streak on the nasal region, the tip of the tail, and the meta- 

 carpus and metatarsus, all of which are black. The yellow hairs of 

 the body finely grizzled with black. 



Horns, skull, and teeth of adult not yet known. In the type 

 skull, that of a half-grown animal, the anteorbital fossae are of 

 moderate depth, and the mesial notch on the palate is about 1 mm. 

 in advance of the lateral ones. 



Dimensions of type, immature c? . — Height at withers 410; ear 

 75 ; hind foot 206. 



Hab. W. Africa. Gambia [Whitfield (Brit. Mus.)]. 



Of this pretty species there are only in the Museum immature 

 and young specimens, and from this material I am unable to come 

 to a definite conclusion as to its relationship. In its general ap- 

 pearance, however, it has a certain amount of resemblance to the 

 Duiker group, of which it may be the West-African representative, 

 and 1 have therefore in the synopsis included it provisionally in the 

 same section as C. grimmii and abyssinicus. I should, however, feel 

 no surprise if the examination of adult skulls and horns proves this 

 conclusion to be wrong. 



17. Cephalolophus abyssinicus, sp. n. 



Size about one-third smaller than that oiC. grimmii. Ears elongate, 



1 From another specimen. 



■^ Collected in February, 1814. Type of A. ceerulea.
