F. rodgersi was named by the late John Cassin from a specimen said to have been 

 obtained in the South Indian Ocean (Pr. Acad. Philad., 1862, p. 326) by Commodore 

 John Rodgers, commander of the United States North Pacific Exploring Expedition ; 

 but Dr. Elliott Coues corrected this statement, though the exact locality was not 

 then known (Pr. Acad. Philad., 1866, p. 29). 



Rodgers' Petrel, or " Lupus," as it is called by the natives, is an inhabitant of 

 the Pribylof Islands, where it is said to be the only representative of the Procellariince ; 

 it is abundant over all the deep water areas of the Bering Sea, extending into the 

 Arctic Ocean to the vicinity of the Ice Pack. It rarely visits the eastern shores from 

 the mouth of the Kusoquim to the head of Norton Bay, the shallow and muddy water 

 apparently not providing the food on which the bird subsists. On the western coasts, 

 in the neighbourhood of Plover Bay and Lawrence Island, thence north through the 

 Bering Straits, and along the Siberian shore, the birds were seen in abundance during 

 the visit of the " Corwin," while the shallow character of the water on the American 

 coast north of the Straits again failed to attract the birds. It was noticed that areas 

 sometimes frequented by large numbers of F. rodgersi would on other occasions be 

 absolutely devoid of them (Nelson, Cruise of the " Corwin," p. 112). This Fulmar
