Fore-feet rather large ; claws mdistinct; tail very short, coni- 
cal; hind-feet large, with the three middle claws long, subcylin- 
drical, the 5th or mner one rudimentary ; toe-flaps very long, the 
outer one broad, 2nd, 3rd and 4th rather longest and narrow, 
the 5th shortest, all much longer than the very short toes; fur 
rather rough, of the head, neck and chin longer ; hair cylindrical ; 
under-fur none. 
The skulls of the adult Arctocephali have been mistaken for 
the skulls of this genus, but the form of the hinder part of the 
palate, which is little altered by the age of the specimens, at 
once separates the two genera. I was formerly inclined to be- 
lieve that the form of the hinder part of the palate altered, but 
the examination of the skin, with its skull attached, of an adult 
Arctocephalus lobatus, has proved the error of this theory.
