404 THE ZOOLOGIST. 



Magazine, who considers it a vegetable-feeder — is a true carnivore, 

 the peculiar conformation of the skull being correlated with the 

 support and use of its enormous tusks. With these it digs up the 

 mollusca which form its principal food. 



The Otariidce, or Eared Seals, form the first division ; these 

 are chiefly distinguished from their congeners by the following 

 characters : — They all possess external ears or conches, turn the 

 hind limbs forward to aid in terrestrial progression, and are 

 distinctly and jealously polygamous in their habits. Some of 

 the species are commercially valuable, as furnishing the " seal- 

 skin" of fashion; these, which are known as " Sea Bears," are 

 smaller than those without this valuable coating, which are 

 called " Sea Lions." 



In bis ' History of N. American Pinnipeds,' Mr. Allen recog- 

 nizes nine species of Otariidce, of which five are hair Seals, or 

 Sea Lions, and four are fur Seals ; but as they are very widely 

 distributed and still imperfectly known, there are probably a 

 greater number. They are : — 



1. Oturia jubata. The large " Sea Lion " of the south coasts of South 

 America. 



'2. Phocarctos hookeri. Auckland Isles. 



3. Eumetopias stelleri. The large northern "Sea Lion" of the coast 



of California, and North of Japan. 



4. Zalophus calij "or aianus. The lesser " Sea Lion" of California and 



Faralloue Islands. 



5. Zalophus lobatus. The lesser " Sea Lion" of the Australian coast, 



with soft under fur. 



6. Callorhiuus ur sinus. The northern Fur Seal of California and Japan 



northward to Behring Strait. 



7. Arctocephalus australis. Round the south coast of South America, 



from Galapagos Isles to Rio de la Plata. 



8. Arctocephalus aniarcticus. Cape of Good Hope. 



9. Arctocephalus forsteri. The Fur Seal of Australia and New Zealand. 



Of the Walruses, Mr. Allen labours hard to establish two 

 species, whieh he names : — 



1. Odohceuus rosmarus. The Walrus of the North Atlantic and Arctic 



Oceans. 

 Q. Odob&nus obesus. The Walrus of the North Pacific. 



The differences which he points out, however, are slight, and 

 as the ' Vega/ in its N.E. passage to the Pacific, found the 

 Walrus in nearly all parts of the Arctic Ocean, it seems more
