The dimensions of the three skulls of Forest-Pig which I have had for com- 

 parison are recorded in the accompanying table of measurements. The general pro- 

 portions agree approximately with other specimens described before. The dimensions 

 of the female skull from Mau resemble rather closely those of Thomas' type which 

 was a young adult boar. 



The zygomatic arch of the big boar skull is very strongly thickened and has 

 a very rugged surface which corresponds to the enormous wart with which these 

 animals are provided, and which is homologous with the wart below the eye in the 

 Wart-hog. 



In one respect viz. with regard to the shape of the nasals my two specimens 

 from Kenia are more alike inter se than either of them resembles the specimen from 



^ Approximately, tips of nasals broken! 



^ The length of the anterior molars is diminished with the increasing age of the animal.
