Type 



Puffinus, Brisson, Orn., VI., p. 131 (1760) ; Coues, Pr. 

 Acad. Nat. Sci. Philad., 1864, p. 127, 1866, p. 192 ; 

 Ridgway, Man. N. Amer. Birds, p. 58 (1887) ; 

 Salvin, Cat. Birds Brit. Mus., XXV, p. 368 (1896) . . P. puffinus* 



* In his synonymy of the genus Puffinus, Salvin gives the type of Brisson's genus as Puffinus puffinus, 

 which is the name now generally employed. In the body of the ' Catalogue,' however, he calls the 

 typical species Puffinus anglorum, and does not use the duplicated specific and generic name.
