GENERA, . 191 



^as founded on tlie Otaria giUespi of M'Bain. The genera recog- 

 nized Trere live in number, namely : 1. Otaria ("Peron, 181G, 

 type P/iom JM&rtteSclireber"); 2. Arctoceplialus ("F.Cnvier, 1824, ^ 

 .... type Fhoca nrsina Linnieus," lience = Callorhimis, Gray, 

 1859, and not Arctocephalus, F. Cuvier); 3. Einnetopias, Gill (nov. 

 ^en., "type Otaria caJiforniana Jje&aon, = Arctocephalus monte- 

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

 4. ZaJopliuSj Gill (nov. gen., "type Otaria Gilliesptii, Macbain"); 5. 

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

 Arctoceplialm^ F. Cuvier, 1824). Although three new names 

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

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

 phahis, as here defined, with CaUorhimis, 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 hoolieri (then known to Pe- 

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

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

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

 The type of Arctoplioca was originally Otaria philippiij Peters, 

 sp. nov., ^vo\yA\)\y = Arctocephalus faUdandicmj fem.; at all 

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

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

 jSTovember, Phocarctos iilloa was removed bv Dr. Peters to his 

 section or subgenus Otaria^ and Otaria faJklandica, Shaw ( = 

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

 which 0. p)hilippii was now apparently referred as a subspecies 

 or a doubtfid form. Thus Arctocephalus faMandicus is here re- 

 moved from Arctocephalus, where he formerlj" idaced it, to be-" 

 come a new type oi Arctophoca ! 



In September, 1866, | Gray adopted the above named generic 

 and subgeneric divisions, to which he added J^eophoca as a " new 

 genus," based on his Arctocephalus Johalus, referred previously 

 by Peters to Zalophus^ and Euotaria and Gypsophoca as subgen- 

 era of Arctocephalus. Euotaria was based on his ArctocephaJus 

 nigrescens, and Gypsophoca on his Arctocephalus cinereus. In
