Eumetopias jubata Schrijber. (With a mane.) 



STELLAR SEA LION. 



Externally very similar to Zdophus calif omiamis; supposed 

 to average larger; colors similar and as variable. 



Type locality, North Pacific Ocean. 



Stellar Sea Lions range from Bering Straits east and south 

 along the Pacific coast of North America to the Farallone Is- 

 lands, California. I have never seen this species, but specimens 

 of it from the Farallone Islands are in scientific collections. None 

 are known from further south however, and this species is prob- 

 ably much less common there than the California Sea Lion. Ex- 

 ternally the two species seem to be much alike, but probably an ex- 

 pert would see differences on comparison. The gap in the molars 

 in the tooth row of the Stellar Sea Lion is quickly seen by any one 

 who has an opportunity for such examination. 



The habits of the two species are similar though the Stellar 

 Sea Lion seems to migrate with more regularity. There is a dif- 

 ference in their voices, however, the utterance of the Stellar Sea 

 Lion being a steady roar while that of the California Sea Lion 

 is broken intO' barks.

 at base, convex in upper outline ; sa'fgital and occipital crests not
