2 HAND-LIST or SEALS, MOESES, 



the northern Sea-bear (OaUorJiinus io-simis), figures the skull and 

 teeth of two adult animals and the skull of one only thirtj'-five days 

 old — the latter showing the teeth exactly placed as in the figures 

 of the two adult specimens. These skulls also exhibit the varieties 

 that exist in the form of the hinder opening to the nostrils of the 

 same species, the chief difference arising in the more or less imperfect 

 manner in which the hinder margin of the palate is developed.

 Lower grinders 4-lobed. Palate-opening arched, with a notch 

 in the middle. Crown of the adult skull with an elongate linear 

 ridge between the temporal muscles, suddenly diverging behind. 

 Grinders : upper front roundish, the rest with comjjreased crowns 

 and with an obscure marginal lobe in front and a rather larger 

 one behind ; lower grinders with one marginal tubercle before and 

 two behind the rather larger central one ; the second lower grinder 

 placed rather obliquely to the series. The teeth in the very young 

 skull are crowded, the 2nd and 3rd upper and lower grinders being 

 placed obliquely to the line of the jaw, the 3rd and 4th level; but 

 this is not so distinct in the adult skull.
