First International Symposium on 

 Cetacean Biology. His paper was not pub- 

 lished until 1966 (Ichihara, 1966). Mean- 

 while, Zemsky and Boronin (1964) pub- 

 lished the name brevicauda without calling 

 it a new subspecies and without crediting 

 Ichihara. The taxonomic status of blue 

 whales off the coasts of Chile and Peru 

 is not settled. 



Genus MEGAPTERA Gray, 1846 



Megaptera novaeangliae Borowski, 1781 

 (humpback whale). Nearly worldwide; 

 winters largely in tropical waters near 

 islands or the coast, summers in tem- 

 perate and subpolar waters. This species 

 shows little or no geographical variation 

 in size; the several discrete populations 

 differ in the frequency of color varia- 

 tions. 



Order ODONTOCETI 



Family PLATANISTIDAE 



Genus PLATANISTA Wagler, 1830 



Platanista gangetica Lebeck, 1801 (susu; 

 Ganges dolphin). Ganges, Brahmaputra, 

 and Indus Rivers and their larger tribu- 

 taries from tidal limits to the foothills. 



Genus INIA D'Orbigny, 1834 



Inia geoffrensis Blainville, 1817 (bouto; 

 bufeo; Amazon dolphin). Amazon and 

 Orinoco basins of South America, David K. 

 Caldwell (Marineland of Florida) and 

 Robert L. Brownell (Smithsonian Insti- 

 tution) are studying geographical variation 

 in this species. 



Genus LIPOTES Miller, 1918 



Lipotes vexillifer Miller, 1918 (pei c'hi; 

 white flag dolphin; Chinese lake dolphin). 

 Restricted to Tung-t'ing Hu (Lake) on the 

 upper Yangtze River, China, 



Genus PONTOPORIA Gray, 1846 



Pontoporia blainvillei Gervais, 1844 

 (franciscana; La Plata dolphin). Coastal 

 waters and estuari^es of eastern South 

 America, from Baia de Santos, Brazil, 

 to Golfo San Matias, Argentina. 



Family DELPHINIDAE 



Genus STENO Gray, 1846 



Steno bredanensis Lesson 1828 (rough- 

 toothed dolphin). All tropical and warm 

 temperate seas. 



Genus SOUSA Gray, 1866 



The taxonomy of the humpbacked dolphins 

 is greatly in need of revision. Five nominal 

 species are recognized, but individual, sexual, 

 age, and geographic variation have not been 

 adequately studied. 



Sousa teuszi Kiikenthal, 1892 (vernacular 

 name?) Coastal waters of west Africa 

 from Seliegal to Cameroon. 



Sousa plumbea G. Cuvier, 1829 (plumbeous 

 dolphin; lead-colored dolphin). Coastal 

 waters of the northern Indian Ocean; 

 recorded from Arabian Sea, Gulf of Aden, 

 Red Sea, Persian Gulf, Karachi, the 

 Malabar Coast, Ceylon, Madras, Burnna, 

 and the Strait of Malacca. 



Sousa lentiginosa Owen, 1866 (speckled 

 dolphin; boUa gadimi). Recorded from 

 South Africa, Zanzibar, Somalia, India, 

 and Ceylon; questionably recorded from 

 Australia, 



Sousa borneensis Lydekker, 1901 (Bornean 

 white dolphin). South China Sea from 

 Sarawak coast of Borneo to Gulf of Thai- 

 land; doubtfully recorded from Strait of 

 Malacca. 



Sousa chinensis Osbeck, 1765 (Chinese white 

 dolphin). Coast of southej-n China, and 

 lower reaches of Yangtze, Foochow, and 

 Canton Rivers. 



Genus SOTALIA Gray, 1866 



Further taxonomic studies of this genus 

 are needed. Two species are recognized-- 

 one chiefly in coastal and estuarine waters, 

 the other in fresh water. The differences 

 between them are slight; perhaps they are 

 subspecies of a single species. (The Old 

 World species formerly placed in Sotalia are 

 now placed in a separate genus, Sousa .) 



Sotalia fluviatilis Gervais and Deville, 1853 

 (tookashee). Amazon River and its tribu- 

 taries; either this form or S. guianensis 

 occurs in the Orinoco River. 



Sotalia guianensis Van Beneden, 1864 

 (Guiana dolphin). Coastal waters and lower 

 reaches of rivers of northeastern South 

 A m e r c i a, from Lake Maracaibo, 

 Venezuela, to Rio de Janeiro, Brazil. 

 Either this form or S_. fluviatilis occurs 

 in the Orinoco River. 



Genus TURSIOPS Gervais, 1855 



The taxonomy of this genus is under study 

 by Robert L. Brownell. 



Tursiops truncatus Montagu, 1821 (bottle- 

 nosed dolphin). Widely distributed intem- 

 perate and tropical waters, mostly close 

 to shore and near islands. Ranges north 

 to Japan, Baja California, southern 

 Greenland, and Norway; south to southern 

 Australia, New Zealand, Chile, Argentina, 

 and South Africa. Several supposed races 

 or specie-s have been named, but their 

 characters and ranges are poorly de- 

 fined. T_. _t_, aduncus Ehrenberg, 1833,
