280 AFRICAN GAME ANIMALS 



the upper altitudes of the Kenia forest, recorded by Lonn- 

 berg, is considerably greater than any known wart-hog skull, 

 being i8X inches in length. Adult female skulls are smaller 

 than those of the males, averaging about isH inches in great- 

 est length. The tusks or upper canine teeth of the forest hog 

 do not show such great development as takes place in the 

 wart-hog. The larger of the two boars in the National 

 Museum has an exposed length of tusk of 5^ inches. Ward 

 records two specimens from Mount Kenia in which the ex- 

 posed portions of the tusks measure 8^ and y}^ inches, 

 respectively. The former of these may be taken as the 

 record tusk length. 



Mount Kenia is the farthest eastern point at which for- 

 est hogs have been collected, there being yet no evidence 

 of their occurrence in the extensive forests of Mount Kili- 

 manjaro. On Kenia they are known to occur from the 

 lower edges of the forest, at four thousand feet, to its upper 

 limits, at ten thousand feet, where the vegetable growth is 

 chiefly giant bamboo. At this extreme upper limit Akeley 

 has noted extensive areas rooted up by forest hogs, and in 

 places the uprooted vegetation, consisting of herbs and grass, 

 massed into small mounds like haycocks. In places where 

 the forest hog is abundant definite paths are made through 

 the undershrubs of the forest, and where the growth is 

 dense veritable tunnels are formed. They are much more 

 strictly confined to the forest than the bush pigs, and never 

 leave it to make forages into native fields, or shambas. 

 Like the wart-hog, they are much less gregarious in habits 

 than the bush pig, often living a solitary life. Specimens 

 have been secured by sportsmen and naturalists on the 

 northeast, southeast, and southwest slopes of Mount Kenia; 

 on the Aberdare Range in the vicinity of Nyeri Hill ; on the 

 summit of the Kikuyu Escarpment ; in the Mau forest near 

 Enjoro and on its summit at Molo; in the Nandi reserve, 

 at the base of the Mau Escarpment in the Kakumega forest, 

 near the shores of the Victoria Nyanza ; and on the slopes 

 of Mount Elgon.
