I have not seen any skull or specimens from Japan ; so that I am 

 not quite sure that the specimens from the coast of Asia are the same 

 as those from the west coast of America. 



6. NEOPHOCA. 



Palate concave, broad, as broad before as at the hinder part of 

 the tooth-line, then rather suddenly contracted. The hinder nares 

 broad, rather longer than broad, with the front edge broadly arched, 

 which is further back than the front edge of the orbital process of 

 the zygomatic arch, or malar bone, which is thick and flat. Fur 

 with very little under-fur. Flap of toes moderate.

The upper grinders all single-rooted, the root of the last two (the 

 fourth and fifth) being rather compressed, with an obscure central 

 longitudinal groove on the inner side ; the first two grinders of the 

 lower jaw with oblong, the last three with compressed roots, and the 

 fourth and fifth with a slight longitudinal groove on the side. 



In the younger skulls the roots of the grinders are more oblong, 

 less compressed, and do not show the lateral grooves, as far as the 

 teeth can be seen without being drawn from the sockets. In the
