192 FAMILY OTARIID.E. 



1868 * he raised Euotaria and Gypsophoca to the rank of genera r 

 ten genera of Eared Seals being now recognized by this author. 

 In his formal synopsis of the family presented in 1869,t these 

 ten genera were all retained, and are the following : 



1. Otaria. 



2. Callorhinus. 



3. Phocarctos. 



4. Arctocephalus. 



5. Euotaria. 



6. Gypsophoca. 



7. Zalophus. 



8. Neophoca. 



9. Euinetopias. 

 10. Arctophoca. 



In 1871 he again treated two of them (Euotaria and Gypso- 

 phoca) as subgenera of Arctocephalus, thereby reducing the 

 number of genera to eight. In 1873 f eight genera of " Sea 

 Bears' 7 alone (i. e.. Eared Seals exclusive of Otaria) are enumer- 

 ated, Euotaria being omitted. In 1874, however, both Euota- 

 ria and Gypsophoca are given full generic rank, but no reference 

 is made to Arctophoca, the species (Arctophoca philippii) formerly 

 referred to it being neither recognized nor accounted for. The 

 number of genera is thus reduced to nine. Dr. Gill, in 1872 1| 

 and in 1876, fl retained the five generic groups first recognized 

 by him in 1866, with, however, the corrections in nomenclature 

 introduced by Gray and Peters later in the same year. These 

 five genera, namely, Otaria, Eumetopias, Zalophus, Callorhinus, 

 and Arctocephalus, were adopted by myself in 1870, in my paper 

 on the Eared Seals of the North Pacific.** 



Dr. Peters, in 1871,tt referred all the South American Fur 

 Seals (of which he then recognized four, namely, A. falklandicus, 

 A. nigrescens, A. argentata, A. philippii) to his subgenus ("Unter- 

 gattung") Arctophoca. Dr. Peters's later views respecting the 

 genera of the Otasriidce are given in his paper on the Eared Sdbls 

 published in August, 1877,f | in which he reduces the genera to 

 three, namely, Otaria, Eumetopias, and Arctocephalus. The Fur 

 Seals are all united under Arctocephalus; Otaria includes only 0. 

 jubata (to which his 0. leonina and 0. ulloce are referred as " Lo- 

 calrassen"), Eumetopias being made to include all the other
