319. Hydrobates pelagicus (L.)— THE STORM-PETREL. 



Procellaria pelagica Linnaeus, Syst. Xat., ed. x, i, p. 131 (1758— 

 ' ' Habitat in albo Oceano." Restricted typical locality : coast of Sweden). 

 Procellaria pelagica Linnaeus, Yarrell, iv, p. 42 ; Saunders, p. 727.

 bly an islet off Lundy, several islands off southern portion of Welsh

OCEANODROMA LEUCORHOA 



320. Oceanodroma leucorhoa (Vieill.)— LEACH'S FORK- 

 TAILED PETREL. 



Procellaria leucorhoa Vieillot, Xouv. Diet. d'Hist. Nat., nouv. 

 ed., XXV, p. 422 (1817 — Picardy in France). 



Cymochorea lencorrhoa (Vieillot), Yarrell, iv, p. 37 : Oceanodroma leucorrhoa 

 (Vieillot), Saunders, p. 729. 



*In the Cat. B. Brit. Mvs. this species has been called Procellaria 

 pelagica, and it has been stated that P. pelagica was the type of Procellaria. 

 This is an error (c/. Nov. Zool., 1910, p. 497). American and other authors 

 have accepted the generic name Thalassidroma, but Hydrobates is older, and 

 it need not be rejected on account of the previous name Hydrobafa. — E.H.
