THE CROWNED DUIKER 



( CeplialopJms coronatiis) 



This species, which was named by Dr. Gray in 1843 on the 

 evidence of Gambian specimens in Lord Derby's menagerie at 

 Knowsley, may perhaps be regarded as the West African repre- 

 sentative of the duikerbok. Standing about 15 or 16 inches at the 

 shoulder, it is characterised by the bright yellow colour of the coat, 

 with a faint suffusion of black ; there is, however, a dark streak on 

 the top of the nose, and the tip of the tail and the legs below the 

 knees and hocks are blackish brown or black. Further specimens are 

 required to illustrate fully the affinities of this species. 



Although typically from Senegambia, this species is stated to 

 range into Nigeria and the Lake Tchad district. 



THE YELLOW-BACKED DUHvER 



( CeplialopJnis sylviailtoi-) 

 (Plate vi, fig. i) 



With this, the largest, member of the genus we come to the second 

 group, in which the horns incline backwards more or less nearly in the 

 plane of the nose. The number of forms which have received separate 

 names is very large ; and as many of them are evidently more or less 

 closely allied to one another, it is probable that in several instances 

 they might advantageously be reduced to the rank of races. In the 

 present state of our knowledge it seems, however, best to follow the 

 arrangement generally adopted and to allow specific rank to nearly 

 all. As the majority are of comparatively little interest to sportsmen, 

 they are treated as briefly as possible. 



The "bush-goat," as the yellow -backed species is called by 

 Englishmen on the west coast, is easily recognised not only by its 

 large relative size, but likewise by its peculiar and characteristic type 

 of colouring. 



Standing about 34 inches at the shoulder, this antelope is of heavy 

 and ungainly build, with short, broad, and rounded ears, and the coat 

 very short on the fore-quarters, but longer on the loins, where, however,
