distance of 80 to 100 m. animals that 

 they identified as sea cows. We doubt the 

 identification. Surely, over a period of 

 two centuries, a remnant stock would 

 have been seen by coastal natives. 



Family TRICHECHIDAE 



Genus TRICHECHUS Linnaeus, 1758 (mana- 

 tees) 



General range, shallow tropical marine 

 waters, estuaries, and rivers on both sides 

 of the Atlantic Ocean. 



Trichechus manatus Linnaeus, 1758 (Carib- 

 bean manatee). Two races have been 

 described: T_, _m. manatus from the sea 

 coast, and lower reaches of rivers, from 

 Bay of Campeche, Mexico, to Rio Atrato, 

 Colombia, and in the Bahamas and the 

 Greater Antilles; and T. m. latirostris 

 Harlan, 1824 from the coast and coastal 

 rivers of United States from Beaufort, 

 N.C., to Florida Keys and coasts of Gulf 

 of Mexico; westward along coast of Texas 

 to mouth of Rio Grande, Now extinct in 

 many parts of its former range. 



Trichechus senegalensis Link, 1795 (West 

 African manatee). Coastal lagoons and 

 the lower reaches of rivers from Senegal 

 to the Cuanza River, Angola, and in the 

 Niger and Benue drainages of Nigeria. 



Trichechus inunguis Natterer, 1883 (Amazon 

 manatee). Rivers of northeastern South 

 America, particularly the Amazon and 

 Orinoco systems. 



Order MYSTICETI 



Family BALAENIDAE 



Genus BALAENA Linnaeus, 1758 



Balaena glacialis Miiller, 1776 (black right 

 whale). Temperate waters of the North 

 Atlantic (B. g, glacialis ), the North Pacific 

 (B._g_. japonica Lacep'ede, 1818), and the 

 Southern Hemisphere (B. g. australis 

 Desmoulins, 1822), The valTdity of the 

 three nominal subspecies has not been 

 confirmed. 



Balaena mysticetus Linnaeus, 1758(bowhead 

 whale). Arctic waters. There are four 

 geographically isolated populations; 

 (1) From Spitzbergen west to east Green- 

 land; (2) in Davis Strait, Baffin Bay, 

 James Bay, and adjacent waters; (3) in 

 the Bering, Chukchi, and Beaufort Seas; 

 and (4) in the Okhotsk Sea. The Alaskan 

 Eskimo recognize two kinds: the larger 

 " kairalik" or true bowhead, and the smal- 

 ler " ingotok " (known as the "poggy" to 

 the 19th-century American whalers). We 

 believe that the ingotok is most likely a 

 young bowhead; the taxonomy of these 



whales is being studied by Floyd Durham 

 of the University of Southern California. 



Genus CAPEREA Gray, 1864 



Caperea marginata Gray, 1846 (pygnny right 

 whale). Southern Ocean; known only fronn 

 strandings on New Zealand, Australia, 

 South America, and South Africa. 



Family ESCHRICHTIIDAE 



Genus ESCHRICHTIUS Gray 1864 



Eschrichtius gibbosus Erxleben, 1777 (gray 

 whale). Shallow coastal waters of the 

 North Pacific, from the Gulf of California 

 to the Chukchi Sea on the eastern side, 

 and from Korea to the Okhotsk Sea on 

 the western side; formerly in the North 

 Atlantic. If the Pacific population is 

 eventually shown to be subspecifically 

 distinct from the extinct North Atlantic 

 population, the name _E. g. glaucus Cope, 

 1868, is available for it. 



Family BALAENOPTERIDAE 



Genus BALAENOPTERA Lace'pede, 1804 



Balaenoptera acutorostrata Lace'pede, 1804 

 (minke whale; little piked whale). Widely 

 distributed in all oceans, though rare in 

 tropical waters. In some SouthernHemis- 

 phere waters, what is presumably a dif- 

 ferent color phase predonninates; the 

 name bonaerensis Burmeister, 1867, has 

 been applied. Specimens from Ceylon have 

 been described as a separate race, B. a. 

 thalmaha Deraniyagala, 1963. 



Balaenoptera edeni Anderson, 1878 (Bryde 

 whale). Tropical coastal waters of the 

 Atlantic, Indian, and Pacific Oceans. 



Balaenoptera borealis Lesson, 1828 (sei 

 whale). All oceans. Two races distin- 

 guished, a smaller one (B^. _b. borealis ) 

 in the Northern Hemisphere, a larger 

 one (B. b. schlegeli Flower, 1865) in 

 the Southern Hemisphere. 



Balaenoptera physalus Linnaeus, 1758 (fin 

 whale). All oceans, but rarely in tropical 

 waters or among pack ice. Two races 

 are recognized--a smaller Northern 

 Hemisphere form (B. p. physalus ) and a 

 larger Southern Hemisphere form (B. p. 

 quoyi Fischer, 1830). 



Balaenoptera musculus Linnaeus, 1758 (blue 

 whale). All oceans. Three races are 

 recognized; a small one (B. m_. musculus ) 

 in the North Atlantic and Nor I'. Pacific; 

 a large one (B. ni. intermedia Burmeister, 

 1871) that spends the summer in Ant- 

 arctic waters; and a pygmy race (B. m . 

 brevicauda Zemsky and Boronin, 1964) 

 in the southern Indian Ocean. The sub- 

 species brevicauda was proposed by 

 Ichihara in a paper read in 1963 at the
