concave, and sides of nasal region sloping evenly outwards, 

 as in the next, without the sharp lateral angulation of the 

 nasals found in FotamGchccrus and Sus. Coloration of young

The distributional area is probably co-extensive with the 

 great forest-tract of equatorial Africa, in which it is known 

 to extend from the Cameruns in the west, to the Ituri and 

 Semliki A^alleys in the east, while nortliwards it reaches 

 southern Abyssinia.

Typical locality the Kenia district of British East Africa : 

 the range co-extensive with that of the genus. 



Size very large, build heavy, and limbs relatively long ; 

 coat long, coarse, and wholly black, becoming sparse in old 

 age ; skin Ijlackish grey. 



The external characters by which IT. ituriensis, from the 

 Ituri A^alley (with which i/". (jigliolii, from the Upper Congo, 

 is almost certainly inseparable), is stated to be distinguished 

 appear to be mainly features of immaturity ; the under- 

 mentioned skull from the Semliki does not appear to be 

 racially separable from that of the type. 



The two races here recognised are distinguishable as 

 follows : — 



A. Molars broad, with much cement H. ni. meinertzJiageni. 



B. Molars narrower, with less cement H. ni. rimator.
