Genus DELPHINUS Linnaeus, 175 8 



(The species previously called D. 

 roseiventris is now placed in the genus 

 Stenella .) 



Delphinus delphis Linnaeus, 1758 (con-imon 

 dolphin; saddleback dolphin). Widely dis- 

 tributed in warm temperate and tropical 

 waters of all oceans, including the Black 

 Sea. There n-iay be several subspecies, 

 but much more collecting and study are 

 needed. We tentatively follow Hershkovitz 

 (1966) in listing D. capensis Gray. 1828, 

 as a synonym of D. delphis; further study 

 of its status is needed. 



Genus LISSODELPHIS Gloger, 1841 



The two species of this genus differ mainly 

 in color pattern, and they could well be re- 

 garded as races of a single species. 



Lissodelphis borealis Peale, 1848 (northerr 

 right-whale dolphin). Temperate waters 

 of the North Pacific from Japan and the 

 Kurils to British Columbia and California. 



Lissodelphis peroni Lace'pede, 1804 (south- 

 ern right-whale dolphin). Temperate 

 waters of the Southern Ocean. 



Genus CEPHALORHYNCHUS Gray, 1846 



The taxonomy of this genus is in need of 

 revision. See Harmer (1922). The following 

 four species are currently recognized. 



Cephalorhynchus commersoni Lacepede, 

 1804 (piebald dolphin, Commerson 

 dolphin). Tierra del Fuego, Strait of 

 Magellan, coast of Patagonia, and Falk- 

 land Islands; also Kerguelen Island in the 

 southern Indian Ocean. 



Cephalorhynchus eutropia Gray, 1849 (white- 

 bellied dolphin; black dolphin). Coast of 

 Chile between lat. 33° and 40° S. 



Cephalorhynchus heavisidei Gray, 1828 

 (tonine; Haviside [sic] dolphin). Cape of 

 Good Hope. 



Cephalorhynchus hectori Van Beneden, 1881 

 (Hector dolphin). Coastal waters of New 

 Zealand. Individuals with variant color 

 patterns have been named C.. albifrons 

 True, 1899, and C. h, bicolor Oliver, 

 1946. Also said to occur in Sarawak, 

 Borneo. 



Genus PEPONOCEPHALA 

 Norris, 1966 



Nishiwaki and 



Peponocephala electra Gray, 1846 (broad- 

 beaiiad dolphin; many-toothed blackfish). 

 Tropical Atlantic, Indian, and Pacific 

 Oceans. 



Genus FERESA Gray, 1871 



Feresa attenuata Gray, 1875 (pygmy killer 

 whale). Known only from Se'negal, Japan, 

 Hawaii, and the "South Seas." 



Genus PSEUDORCA Reinhardt, 1862 



Pseudorca crassidens Owen, 1846 (false 

 killer whale). All temperate and tropical 



Genus GLOBICEPHALA Lesson, 1828 



There appear to be two well-defined species, 

 the ranges of which overlap off the middle- 

 Atlantic coast of the United States, off south- 

 ern Europe, off South Africa, and perhaps 

 elsewhere. 



Globicephala melaena Traill, 1809 (common 

 pilot whale; common blackfish; pothead 

 whale). Nominate race in the temperate 

 North Atlantic Ocean; G^. m. edwardi A. 

 Smith, 1834, throughout temperate waters 

 of the Southern Hemisphere. 



Globicephala macrorhyncha Gray, 1846 

 (short-finned pilot whale; short-finned 

 blackfish). Tropical Atlantic, Indian, and 

 Pacific Oceans. We believe G. sieboldi 

 Gray, 1846, of the temperate (and tropi- 

 cal?) North Pacific is conspecific with 

 G. macrorhyncha , although it nnay be 

 recognizable at the subspecific level. The 

 taxonomy of Pacific Globicephala is being 

 studied by R. L. Brownell, D.K.Caldwell, 

 T. Kasuya, and M. Nishiwaki. (The latter 

 two are in the Ocean Research Institute, 

 University of Tokyo.) 



Genus ORCINUS Fitzinger, I860 



Orcinus orca Linnaeus, 1758 (killer whale). 

 All oceans, chiefly in coastal waters and 

 cooler regions. 



Genus ORCAELLA Gray, 1866 



Orcaella brevirostris Owen, 1866 (Irrawaddy 

 dolphin). Coastal waters from the Bay of 

 Bengal east to New Guinea and northern 

 Australia; ascends far up the Mekong, 

 Irrawaddy, Ganges, and other rivers. The 

 population in the Irrawaddy River is 

 sometinnes considered a separate sub- 

 species, O. b. fluminalis Anderson, 1871. 



Genrs PHOCOENA G. Cuvier, 1817 



According to Norris and McFarland (1958) 

 the genus includes four species. 



Phocoena phocoena Linnaeus, 175 8 (harbor 

 porpoiseTi Coastal waters of the North 

 Atlantic from Delaware and the Mediter- 

 ranean and Black Seas (one record from 

 Se'negal) north to Davis Strait, Iceland, 

 and the White Sea; coastal waters of the 

 North Pacific from Japan and Baja 

 California north to Point Barrow, Alaska.
