is most plentiful on the highlands between three thousand

 or in scattered bush. It is rare in the low desert nyikae of 

 the coast slope.

Range. — Nile Valley from the Albert Nyanza north- 

 ward to the Bahr-el-Ghazal and Sobat Rivers; limits of 

 range unknown. 



The Nile wart-hog has been recently separated as a new 

 race on the evidence of a skull collected by the Smith- 

 sonian African expedition at Rhino Camp in the Lado 

 Enclave. The type specimen was collected on the shores 

 of a small pond near Chief Sururu's village in the vicinity 

 of Rhino Camp. The wart-hog had been killed by a lion the 

 night previous to our arrival and the head was the only portion 

 which remained uneaten. Wart-hogs were rare in the Lado 

 Enclave, less than a score being seen by the members of 

 the Smithsonian African expedition during a month's so- 

 journ in the upper Nile district. In addition to those ob- 

 served at Rhino Camp a few were seen in the vicinity of a 

 small lake near Gondokoro. 



The Nile wart-hog differs from csliani of Abyssinia and 

 East Africa by the greater breadth and length of the post- 

 orbital or parietal portion of the skull and the flatter inter- 

 orbital region. Other minor differences from celiani are 

 the absence of elevation of the parietal or lambdoidal crests, 

 which are on the same level as the interorbital region, the 

 narrowness of the choanae posteriorly, and the smaller size 

 of the tympanic bullae. The type is unfortunately an im- 

 mature skull in which the last molar is just erupting and 

 with all the maxillary sutures still evident. Skulls of this 

 age from the highlands of British East Africa show a much 

 narrower, shorter, and more elevated parietal region. In 

 the flatness of the interorbital region and in the general 

 shape of the postorbital part of the skull the type resem-
