BROOKES D UIKER 1 5 7 



orange, with a more rufous tendency on the hind-quarters. With the 

 exception of the brown nose, the face is coloured Hke the body ; but 

 the nape and sides of the neck are brown or blackish, ahhough so 

 thinly haired that the skin shows through and the colour is little 

 affected. A black dorsal stripe commences at the withers, and after 

 becoming narrower and more sharply defined on the loins, is continued 

 on to the tail. With the exception of the brown or blackish fetlocks, 

 the limbs are dull yellowish in tint. 



BROOKE'S DUIKER 



( CepJialopJms brookei) 



The mainland (Fanti) representative of Cephalophus ogt'lbyi, from 

 which it is distinguished by the reversal of the hairs of the nape, the 

 broader dorsal stripe, which stops short of the tail, the lighter colour of 

 the lower part of the legs, and the less swollen frontal region of the skull. 



In size this species is slightly inferior to C. ogilbyi, its general 

 colour being very similar to that of the specimen figured in plate xviii, 

 fig. 2 of the Book of Antelopes under the latter name. That figure 

 probably indeed represents the present species, although the brow 

 lines are too strongly marked, and the limbs, which should be uniformly 

 light to the hoofs, too dark. In ogilbyi the front of the cannon-bones 

 and the whole pasterns are black. The hairs of the middle of the 

 nape are directed forwards for a distance of 3 or 4 inches, as in 

 C. iveynsi and johnstojtz. The broad black dorsal stripe ends 3 or 4 

 inches short of the root of the tail, the latter having the tuft at the 

 tip black and white. 



The species was named in 1903 by Mr. O. Thom.as in the Annals 

 and Magazine of Natural History, ser. 7, vol. xi. p. 290. 



PETERS'S DUIKER 



( CephalopJius callipygus) 



This rare but handsomely coloured species was discovered in the 

 Gaboon by Dr. R. Bucholz in 1874, ^i^*^ named two years later by 

 Dr. Peters. Its most characteristic feature appears to be the broad 

 black dorsal stripe, which commences at the withers, widens out at 

 the loins, and includes the whole of the hind surfaces of the hips
