268 Great and Small Game of Africa 



the plateau of Central Somaliland, and thence into British East Africa. 

 It differs little in size and habits from the other Somali dik-diks, but it 

 may be noted that the horns are slightly longer, a pair measuring as much 

 as 2i inches in length. Giinther's dik-dik, too, is found in small com- 

 panies, three or four at a time, instead of in pairs, and the females are, in 

 the opinion of Major Swayne, somewhat larger than the males, so much so 

 that it is safer, if the hunter wishes to bag a buck, to fire at the smaller 

 animals as they start up. They give good sport with shot-gun or rook- 

 rifle, and especially so in the evenings, "when they are at their liveliest."

THE WATERBUCKS AND KOBS 

 Genus Cobus 



The members of this genus, together with the Vaal rhebok, belong 

 to a sub-family of large or medium-sized African antelopes typified by the 

 reedbucks, and hence known as the Ceruicapriruz. All have the muzzle 

 naked, the face- glands rudimentary or wanting, the tail moderate, the 

 lateral hoofs well developed, and the horns confined to the male sex. The 

 upper cheek-teeth are of a narrow sheep-like type, and the second pair 

 of lower incisors have expanded crowns. Pits for the reception of face- 

 glands are wanting in the skull. In form the long or medium-sized horns 

 of the bucks are never twisted, but are generally curved backwards at the 

 bases, where they are strongly ridged, after which they curve upwards and 

 forwards to the smooth tips ; they may, however, have a sinuous flexure 

 or be perfectly straight. 



The waterbucks and kobs may be distinguished from the other 

 members of the sub-family by their large size, long and somewhat lyrate
