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

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

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

 for that species. 



tls not A. monteriensis Gray identical with Otaria Stdleri Mull. Arc. far 

 Nat. 1841,1. 330? 



J TRICHECHUS was originally based solely on the Manati (T. Manatus) 

 by Linnaeus, Syst. Nat. 10 ed. 1758, 1. 34. It must therefore be retained for 

 that animal.
