46 BULLETIN OF THE 



between the single known species of Eumetopias (E. Stelleri) and the 

 single known species of Otaria (0. jubata). 



Eumetopias differs from Zalophus through the presence of a wide 

 space between the fourth and fifth pairs of upper molars, the less 

 emargination of the posterior border of the palatine bones, the quad- 

 rate instead of the triangular and posteriorly pointed form of the post- 

 orbital processes, the less relative breadth of the posterior nares, and 

 the larger size of the facial angle ; also through its much broader muz- 

 zle, the less degree of the postorbital constriction of the skull, and its 

 much less developed sagittal crest. It differs from Neophoca Gray, as 

 nearly as can be determined from the published figures and defective 

 descriptions, in nearly the same manner.
