282 AFRICAN GAME ANIMALS 



by a bare interspace but continued again on the rump. 

 The hair covering of the sides, under-parts, and legs is very- 

 short and sparse, the individual hairs being separated by 

 interspaces of half an inch or more. The tail is slender and 

 quite naked with a tuft of black hair at the extreme tip. 

 The female lacks the warts of the male with the exception 

 of a small rudiment below the eye and the ridge of whiskers 

 on the cheek, has much smaller upper incisors and smaller 

 body size, but shows no differences in coloration or hair 

 covering. The mammae are only four. The young differ 

 from those of other wild hogs by being uniform in color 

 without lighter stripes or spots. The wart-hogs are con- 

 fined at the present time in their distribution to Africa, to 

 which region they appear always to have been limited; for 

 no trace of them has been discovered in the fossil-bearing 

 beds of Europe and Asia. Two Pleistocene species are 

 known from the extreme points of the African continent, 

 one from the Cape region and the other from Algeria. 

 Three distinct species may be distinguished by differences 

 in dentition and shape of skull. Two of these species lack 

 both upper and lower incisor teeth and occur widely sep- 

 arated from one another; one, cethiopicuSy at the Cape of 

 Good Hope, and the other, delamerei, in the desert region 

 of East Africa and Somaliland. The other species, to which 

 the name ajricanus has been given, occupies the intermedi- 

 ate territory from Natal northward to Abyssinia and west- 

 ward to Senegal. This species has two well-developed 

 upper incisor teeth and either four or six lower ones. Sev- 

 eral geographical races of this species may be recognized 

 which are based on differences in skull shape. It is this 

 wide-spread species alone which is familiar to sportsmen, 

 the Cape, cethiopicus^ being now doubtless extinct and the 

 northern one, delamerei, being quite rare in the region of its 

 occurrence. 



Wart-hogs were common on the bare plains of East 

 Africa, and they occasionally went among the thin groves 

 of thorn-trees. We found them in the Lado. They were 

 never found in thick forest. When persecuted by man they
