the other side of the jaw this tooth appears to have been broken and resorbed as 

 there is a mark in the jaw bone. 



The female specimen from Kenia has also had on one side of the lower jaw a 

 well developed ig to judge from the size of the alveole, but on the other side' there 

 is only a trace of an alveole. 



These observations prove that there is a considerable variation with regard to 

 the development of the dentition of Hylochcerus, but this variation is probably in- 

 dividual. 



The following measurements of different bones of the skeleton from Mau agree 

 as a rule, more closely with the corresponding measurements recorded by Rothschild 

 and Neuville for their greatest boar from Nandi than with those of the biggest sow 

 (conf. 1. c. p. 160—163). This appears to indicate that the Forest-Pigs attain a greater 

 size on the Mau mountains than in the Nandi forest. The same is probably also the 

 case with the Forest-Pigs of Kenia as the old boar skull picked up there by this 

 expedition is larger than those from Nandi.
