teeth, and four cutting teeth in each jaw; the hooded seal ( Cysto - 
phora ), and elephant seal ( Morunga ), which have the end of the nose 
of the male sex inflatile. The last group of genera are called eared 
seals, because they have small cylindrical external ears ; their toes end 
in very long membranaceous flaps, and the soles of the feet are bald 
and grooved; their nose is simple, as the bear seal (Arctocephalus), 
and the sea lion ( Otaria .)

The third order, or Whales (Cete), are peculiar for their fish-shaped 
nearly bald body; their hinder limbs are united, forming an horizontal 
tail, and they have simply conical rootless teeth, or whalebone in the 
jaws. The more typical kinds have a perfectly bald skin and no whiskers, 
even about the mouth. 
The family of Whales (Bal^nid^e) have a very large head, at 
least one third the length of the body, as the tribe of whales (Bala-
