DR. J. E. GRAY ON THE JAPANESE PIG. [Jan. 28, 



The skulls of the common domestic Pig, which we have in the 

 British Museum, for example, chiefly differ from the skull of a Wild 

 Boar from Germany in the same collection in being smaller and 

 considerably shorter, and in the angle of the forehead being much 

 more acute and sudden, caused by the back of the two skulls being 

 nearly of the same height, while that of the domestic one is generally 

 much the shortest in length. The position and size of the holes for 

 the blood-vessels and nerves are nearly the same in all these skulls. 

 The underside of these two skulls and the forms of the palates are also 



Skull of Sus pliciceps.
