The skulls of four half-grown specimens are aU very uniform in 

 their characters. 



There is in the Museum a skull of a very young Seal which appears 

 to belong to the same species. 



In three of the skulls the outer upper cutting-teeth are very large 

 and acute, more than half the size of the canines, and hlfe them in 

 form. In one skull (perhaps of a female '?) the upper outer canines 

 are much smaller and more slender, not half the size of the same 

 teeth in the other skulls of the same size, and the canines themselves 

 are also much more slender; the front of the palate is also more 

 concave.— G^ray, P. Z. S. 1859, 107. 



The skull of A. IlooJceri, in the concavity and comparative greater 

 width of the palate behind, and in the form of the hinder palatine 

 opening, most resembles that of the genus Otaria ; but it is very 

 distinct from the skulls of that genus.
