Breeds along west coast of North America from San 

 Miguel Island, Calif., northwest to Prince William 

 Sound and the Alaska Peninsula, throughout the 

 Aleutian and Pribilof islands, along the east coast of 

 Kamchatka, throughout the Kuril Islands, and on 

 islands in the Okhotsk Sea. Some move north into 

 the Bering Sea in summer, as far as St. Lawrence Is- 

 land. Sometimes hauls out on ice. The spelling of 

 jubatus follows a rule in International Trust for 

 Zoological Nomenclature (1964:31): "a noun of 

 variable gender ... is to be treated as mascu- 

 line " 



Genus CALLORHINUS Gray, 1859 



Calorhinus ursinus (Linnaeus, 1758) (northern fur 



seal). 



Breeds on Ostrov Tyuleniy (Robben Island) in the 

 Okhotsk Sea, some of the Kuril Islands, the Pribilof 

 and Commander islands in the Bering Sea, and San 

 Miguel Island off southern California. Formerly bred 

 on Ostrov Iony in the Okhotsk Sea 120 miles north of 

 Sakhalin (Stejneger 1898), and possibly on Buldir Is- 

 land in the Aleutians (Murie 1959) and the Farallon 

 Islands off central California (Repenning et al. 

 1971). Bones, including those of young pups, from 

 San Miguel Island, the Monterey area, and Ano 

 Nuevo Point, Calif., and from Bella Bella, British 

 Columbia, suggest that it formerly bred all along the 

 west coast from San Miguel Island to Alaska 

 (Repenning, pers. commun.). 



Genus ARCTOCEPHALUS E. Geoffroy Saint-Hilaire 

 and F. Cuvier, 1826 



The breeding ranges of the species of 

 Arctocephalus are strictly allopatric; further studies 

 on the relationships of these seals are much needed. 

 The present classification follows Repenning et al. 

 (1971). 



Arctocephalus pusillus (Schreber, 1776) (Giant fur 

 seal; Victorian, or Tasmanian, and South African, or 

 Cape, fur seals). 

 There are two widely separated subspecies. Arc- 

 tocephalus p. pusillus breeds in temperate coastal 

 waters from Cape Cross, South West Africa, to Algoa 

 Bay, South Africa; ranges north to Angola. Arc- 

 tocephalus p. doriferus Wood Jones, 1925, breeds 

 along the coast of southeastern Australia from Lady 

 Julia Percy Island east to the Skerries, Victoria, in- 

 cluding coasts of Tasmania and islands in Bass 

 Strait; ranges east to Port Stephens, N.S.W. 



Arctocephalus gazella (Peters, 1875) (Antarctic fur 



seal). 



Islands south of the Antarctic Convergence; South 

 Shetlands, South Orkneys, South Sandwich, South 

 Georgia, Bouvet, Kerguelen (not breeding), Heard, 

 and McDonald. 



Arctocephalus forsteri (Lesson, 1828) (Antipodean fur 

 seal; Western Australian and New Zealand fur seals). 

 Breeds around South Island, N.Z., on nearby suban- 

 tarctic islands (Chatham, Bounty, Antipodes, Auck- 

 land. Campbell, Macquarie, Snares, Stewart, and 

 Solander), and along coast of southwestern Aus- 

 tralia from Eclipse Island, Western Australia, to 

 Kangaroo Island, South Australia. 



Arctocephalus tropicalis (Gray, 1872) (subantarctic 



fur seal). 

 Subantarctic islands of Atlantic Ocean and Indian 

 Ocean, north of the Antarctic Convergence (Tristan 

 da Cunha, Gough, Marion, Prince Edward, Crozet 

 (not breeding), Amsterdam, and St. Paul). Rarely 

 wanders to South Africa, New Zealand, and Mac- 

 quarie Island. 



Arctocephalus australis (Zimmerman, 1783) (South 



American fur seal). 



Falkland Islands; coasts of South America from 

 Tierra del Fuego north to Rio de Janeiro, Brazil, and 

 Lima, Peru. The proposed subspecific separation of 

 the Falkland Islands and mainland populations is 

 not justifiable (Vaz Ferreira 1976). 



Arctocephalus galopagoensis Heller, 1904 (Galapagos 

 fur seal). 



Confined to the Galapagos Islands. 



Arctocephalus philippii (Peters, 1866) (Juan Fernan- 

 dez fur seal). 

 Now known to breed only on the Islas Juan Fer- 

 nandez, Chile. Probably bred formerly on Isla San 

 Felix and Isla San Ambrosio, Chile. 



Arctocephalus townsendi Merriam, 1897 (Guadalupe 



fur seal). 



Now known to breed only on Isla Guadalupe, Baja 

 California. Occasionally seen on other islands off 

 southern California and Baja California (San 

 Miguel, San Nicholas, and Cedros), where it may 

 have bred formerly. An old sealer's report from Isla 

 Socorro (Morrell 1832) and bones from an Indian 

 midden on Monterey Bay (Repenning, pers. com- 

 mun.) suggest that it originally ranged more widely. 



Family MUSTELIDAE 



This family includes the weasels, badgers, otters, and 

 their allies. Only the otters (subfamily Lutrinae) in- 

 clude marine species and only the sea otter is usually 

 regarded as marine, although several species of river 

 otters of the genus Lutra — especially the chungungo, L. 

 felina (Molina, 1782), of Chile and Peru — feed exten- 

 sively in salt water. 



Genus ENHYDRA Fleming, 1822
