* Arctocephalus F. Cuv. was especially established for a species con- 

 sidered identical with Phoca ursina Linn, and as no other species was men- 

 tioned, and, as the identification appears correct, the name must be retained 

 for that species. 



t Is not A. monteriensis Gray identical with Otaria Stelleri Mull. Arc fur 

 Nat. 1841,1. 3301 



t Trichechus was originally based solely on the Manati (T. Manatvs) 

 by Linnaeus, Syst. Nat. 10 ed. 1758, I. 34. It must therefore be retained for 

 that animal.
