71 6 g. Skull of young female. Length , height inches. Nepal; 

 B. H. Hodgson. Nose much narrower and contracted behind in 

 front of the orbit, perhaps the character of the female sex. The 

 skulls of female exotic Pigs are very rare in collections. 



This series of skulls differ in the depth of the concavity on the 

 hinder part of the cheeks in front of the orbit. It is very deep, and 

 with a well-defined wide ridge behind in 716 0, 716 z;, and 716^. 

 It is less marked in the others, in different degrees of distinctness 

 and depth. 



In the skulls of the younger animals the concavity is very shallow 

 behind, and gradually shelving off to the orbit, as in 716 c, 716 w, 

 71 6 »z, 716 <^, 716 a?. It is one of these skulls (716 w) that Mr. Blyth 

 marked as like his type of S. bengalensis. 



The skull of this species is like that of Sus verrucosus from the 

 Malay Islands ; but all the skulls differ from the skulls of S. verru- 

 cosus in the flatness of the zygomatic arch, compared with the thick 

 swollen form of the zygoma in all the skulls of that species. The 

 sides of the lower jaw are convex and swollen, but not so much so 

 as the lower jaw of S. verrucosus. 



b. Concavity on the cheeks of the skull in front of the orbit shallow 

 behind, only separated from the orbit by a narrow ridge.
