Orca ater var. fusca Dall, in Scammon, 1874, Marine mammals of the 

 northwestern coast of North America, p. 298, pi. 17, fig. 3 (animal) 

 [N. Pacific: U.S.A. (type locality: coast of California or Oregon); 

 name based on Scammon's account]. 



Orca antarctica Fischer, 1876, Journ. Zool., 5: 146 [S. Atlantic; name 

 based on M. Dumoutier's drawing and ms. of a killer whale seen at 

 sea between Powell and South Shetland Islands during the "Voyage 

 au Pole Sud" in the Astrolabe and Zelee, commanded by Captain 

 Dumont d'Urville]. 



Physeter microps, Fabricius (not Linnaeus), 1780, Fauna Groenlandica, 

 p. 44 [N. Atlantic (type locality: Greenland seas)]. 



Type : None in existence, name based on a description of the common 

 killer whale of authors. 



Type locality: "Oceano Europaeo." 



Distribution: All seas from Arctic to Antarctic and the coasts of Ant- 

 arctica; in South America from Cabo Corrientes, Buenos Aires (38°50 / S.), 

 Argentina, to Cape Horn, northward on the Pacific side to Conception, 

 Chile (37° S.) ; in the northwest Atlantic as far south as Florida (Moore, 

 1953, Midland Nat., 49: 138) and the Bahamas (Backus, 1961, Journ. 

 Mammal., 42: 418)]. 



Remarks: The name "Grampus" rectipinna Cope was revived for the 

 Northern Pacific killer whale by Scheffer (1942, Murrelet, 23: 44) on the 

 basis of a statement communicated to him by Dr. Remington Kellogg that 

 "all reported observations seem to indicate that the Pacific coast form may 

 have a higher dorsal fin than the Atlantic coast form" [italics mine]. In- 

 deed, Cope, in describing rectipinna said as much but neither he nor anyone 

 else has offered creditable evidence in support. On the contrary, a great 

 amount of individual and sexual variation in the size of the dorsal fin has 

 been observed and convincingly documented (cf. Scammon, 1869, Proc. 

 Acad. Nat. Sci. Philadelphia, 21: 57, figs. 15-17; Scammon, 1874, Marine 

 mammals of the northwestern coast of North America, pi. 17, figs. 1-3; 

 Wilson, 1907 Nat. Antarctic Exped., 1901-1904, Zool., 2: 4, 6, fig. 6, pi. 

 4; Lillie, 1915, British Antarctic (Terra Nova) Expedition, 1910, Zool., 

 1(3): 120. In the absence of any other external or cranial character I 

 treat Orcinus as monotypic.
