GENERA. 191 



-\vas founded on the Otaria gillespi of M'Baiu. The genera recog- 

 nized were five in number, namely : 1. Otaria ("Peron, 1816, 

 type Phocajubata Schreber"); 2. Arctocephalus ("F. Cuvier, 1824, 

 .... type Phoca itrsina Linnseus," hence = CallorMnus, Gray, 

 1859, and not Arctocephalus, F. Cuvier); 3. Eumetopias, Gill (uov. 

 gen., "type Otaria californiana Lesson, = Arctocephalus monte- 

 riensis Gray," the intended type being Otaria stelleri of Miiller) ; 

 4. Zalophus, Gill (nov. gen., "type Otaria Gilliespii, Mac-bain"); 5. 

 Halarctus, Gill ("type Arctocephalus Delalandii, Gray," hence = 

 Arctocephalus, F. Cuvier, 1824). Although three new names 

 were proposed, only two new genera were added, Halarctus be- 

 ing synonymous with Arctocephalus of F. Cuvier, and Arctoce- 

 phalus, as here defined, with Callorhinus, Gray, as speedily and 

 almost simultaneously pointed out by Gray* and Peters,t and 

 as has been since freely conceded by Gill. A few months later 

 Professor Peters t adopted, in a sub gen eric sense, the genera 

 previously recognized by Gray and Gill, and added two other 

 subgenera, namely, Phocarctos and Arctophoca. The type of 

 Phocarctos was Gray's Arctocephalus hooker i (then known to Pe- 

 ters apparently only through Gray's description and figures), 

 with which, however, was associated the Otaria ullocc of von 

 Tschudi, which latter appears to be merely Otaria julata, fern. 

 The type of Arctophoca was originally Otaria philippii, Peters, 

 sp. nov., probably = Arctocephalus falldanrlicus, fern. ; at all 

 events, a Fur Seal from the Island of Juan Fernandez. These 

 groups were first established in May, 18C6, but the following 

 Xovember, Phocarctos ullocc was removed by Dr. Peters to his 

 section or subgenus Otaria, and Otaria falklanclica, Shaw ( = 

 " 0. nigrescens, Gray"), was taken as the type of Arctophoca, to 

 which 0. pliilippii was now apparently referred as a subspecies 

 or a doubtful form. Thus Arctocephalus falklandicus is here re- 

 moved from Arctocephalus, where he formerly placed it, to be- 

 come a new type of Arctophoca! 



In September, 1806, | Gray adopted the above named generic 

 and subgeneric divisions, to which he added Neophoca as a " new 

 genus," based on his Arctocephalus lolatus, referred previously 

 by Peters to Zalophus, and Euotaria and Gypsophoca as subgeu- 

 era of Arctocephalus. Euotaria was based on his Arctocephalus 

 nifjrescens, and Gypsophoca on his Arctocephalus cincreits. In
