Phocide have truly a sub-family value, —the Otariade must be considered ` 
as divisible into two sub-family groups, of which the hair seals consti- 
and Oulophocine t for the fur seals, in m to the different character 
of the pelage in the two groups." To the Trichophocine, are referred the 
genera Otaria, Eume es tor a Zalophus; to the Oulophocine, the genera 
Arctocephalus aud Callor. 
Mr. Allen has riens uem A ENEA for his sub-families, solely from 
the nature of the pelage, the size and form of the entire animal, the 
length of the ears, the length of the toe-flaps of the hinder limbs, and the 
number of molars. His definitions are as follow

We may at once concede the MUN of the distinctions based on 
the pelage, remarking, however, that the character is not as absolute as 
the homologue of the under-fur of the fur-seals, and Gray attributes to 
difference in the extent of the under fur in the species of Arctocephalus,
