GENERA. 191 



was founded on the Otaria gillespi of M'Bain. The genera recog- 

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

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

 , . . . type Phoca ursina Linnaeus," hence = CallorhinuSj Gray, 

 1859, and not Arctocephalus, F. Ouvier) ; 3. Eumetopias, Gill (nov. 

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

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

 4. ZalophuSj Gill (nov. gen., "type Otaria Gilliespiij Macbain"); 5. 

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

 Arctoceplialus , 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- 

 plialusj as here denned, 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 subgeneric 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 Jiookeri (then known to Pe- 

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

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

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

 The type of Arctoplioca was originally Otaria philippii. Peters, 

 sp. nov., probably = Arctocephalus falklandicus, fern. 5 at all 

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

 groups were first established in May, 1866, but the following 

 November, Phocarctos ulloce was removed by Dr. Peters to his 

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

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

 which 0. philippii was now apparently referred as a subspecies 

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

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

 come a new type of Arctophoca ! 



In September, 1866, J Gray adopted the above-named generic 

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

 genus," based on his Arctoceplialus lobatus, referred previously 

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

 era of Arctocephalus. Euotaria was based on his Arctocephalus 

 nigrescens, and Gypsophoca on his Arctocephalus cinereus. In
