Mr. Stejneger has shown (/. c.) that Illiger's name obesus for this 

 species is a nomen nudum, being " without any trace of diagnosis, in- 

 dication, or literary reference whatever"; but on page 68 of the same 

 paper he bestows a tenable name, divergens, upon the animal, which 

 will be the one by which it must hereafter be known.

Subfamily Phocinae.

 has also been employed by some writers as a distinct genus.
