Lissodelphis is not recorded from the 

 North Atlantic, although it is a cold-water 

 form sometimes seen far at sea. 

 Lissodelphis peroni Lacepede, 1804 (south- 

 em right-whale dolphin). Temperate waters 

 of Southern Ocean. 

 Genus Steno Gray, 1846 

 Steno bredanensis Lesson, 1828 (- S. 

 rostratus Desmarest, 1817, preocc.) (rough- 

 toothed dolphin). Temperate and tropical 

 seas of the world. A specimen from the 

 coast of southern East Africa was de- 

 scribed by Mirando-Ribeiro in 1936 as 

 Stenopontistes zambesicus, new genus and 

 species (EUermEin et al., 1953, p. 330). 

 Genus Sotalia Gray, 1866. There is no appro- 

 priate vernacular name for the group, 

 though "river dolphins" and "white dol- 

 phins" have been used. The species are 

 poorly defined. Most members live in trop- 

 ical rivers and estuaries; a few in warm 

 coastal seas. South America, Africa, 

 India, and the Orient (Eraser, 1949, p. 333). 

 Sotalia pallida Gervais, 1855 (= S. tucuxi 

 Gray, 1856; S. fluviatilis Van Beneden 

 and Gervais, 1880) (Amazon river dolphin; 

 bufeo; tucuxi; pirayaguara). Upper Amazon 

 River drainage. (Not to be confused with 

 Inia geoffrensis.) 



Sotalia guiaaensis Van Beneden, 1864 

 (= S. brasiliensis Van Beneden, 1875^ 

 (Guiana river dolphin). Coastal waters 

 and streams of northeastern South America, 

 from Rio de Janeiro to British Guiana. 

 Sotalia chinensis Osbeck, 1765 (= S. 

 sinensis Desmarest, 1822) (Chinese white 

 dolphin). Coast of southern China. For 

 discussion of the name, see Hershkovitz, 

 1961. 

 Sotalia borneensis Lydekker, 1901 (Bornean 

 white dolphin). Sarawak coast of Borneo; 

 doubtfully recorded from Straits of Malacca. 

 Probably closely related to S. chinensis. 

 Sotalia lentiginosa Owen, 1866 (speckled 

 dolphin; bolla gadimi). India, Ceylon; one 

 specimen from False Bay, South .^f^ica. 

 Sotalia plumbea G. Cuvier, 1829 (plumbeous 

 dolphin; lead-colored dolphin). Indian 

 Ocean: Ceylon, Madras, Malabar coast, 

 Karachi, Burma, and Strait of Malacca. 

 Sotalia teuszi KUkenthal, 1892. West Africa, 

 from Cameroons to Sene'gal. 



Genus Tursiops Gervais, 1855 

 Tursiops truncatus Montagu, 1821 (bottle- 

 nosed dolphin). Coastal waters of Europe 

 (including Baltic, Mediterranean, and 

 Black Seas), southeastern United States, 

 West Indies, eastern South America, Sey- 

 chelles, Muscat, Bay of Bengal, New 

 Zealand, Japan, Hawaii, and west coast 

 of North and Middle America. T. t. gilli 

 Dall, 1873 (? = T. nuuanu Andrews, 1911), 

 from the Pacific is distinct from the Atlantic 

 populations. Because it has been inten- 

 sively studied in the wild and in oceanaria 

 it "must now be classed as the best-known 

 cetacean species" (Norris and Prescott, 

 1961, p. 291). 



Tursiops aduncus Ehrenberg, 1833 (= T. 

 abusalam riippell, 1842; T. catalaniaGiay, 

 1862; Sotalia gadamu Owen, 1866) (gadamu). 

 Red Sea, Indian Ocean (west Pakistan, 

 India, Sumatra, Java), South Africa, and 

 Australia. By some authorities (e.g., 

 Tomilin 1957) considered conspecific with 

 T. truncatus. 

 Genus Grampus Gray, 1828 (= Grampidelphis 



Iredale and Troughton, 1933) 

 Grampus griseus G. Cuvier, 1812 (grampus; 

 gray greimpus; Risso dolphin). All seas ex- 

 cept polar. 

 Genus Globicephala Lesson, 1828 

 Globicephala melaena Traill, 1809 (common 

 pilot whale; common blackfish). Nominate 

 race in North Atlantic Ocean; G. m. edwardi

 Pacific?) Oceans. 

 Globicephala scammoni Cope, 1869 (North 

 Pacific pilot whale; North Pacific black- 

 fish). North Pacific Ocean; in eastern 

 waters from Alaska to Guatemala. G. 

 sieboldi Gray, 1846, is probably the correct 

 name for this form, and it is probably 

 conspecific with G. macrorhyncha. 

 Genus Orcaella Gray, 1866 {- Orcella 

 Anderson, 1871) 

 Orcaella brevirostris Owen, 1866 (Irra-
