HYDROBATES PELAGICUS* 



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



PROCELLARIA PELAGICA Linnaeus, Syst. Nat., 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. 



DISTRIBUTION. British Isles. Resident. Breeds Scilly Isles, possi- 

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

 coast, many western isles Scotland, as well as Orkneys and Shetlands, 

 and several islands off north and west coasts Ireland. A pair nested

 British waters, and often driven inland in rough weather ; in winter

DISTRIBUTION. Abroad. Eastern portions of north Atlantic, south 

 to western Mediterranean and west Africa, but rare south of Canary 

 Islands ; also recorded from south Africa and seen in Straits of 

 Bab el Mandeb, but specimens should be compared. 



OCEANODROMA LEUCORHOA 



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

 TAILED PETREL. 



PROCELLARIA LEUCORHOA Vieillot, Nouv. Diet. d'Hist. Nat., notiv. 

 ed., xxv, p. 422 (1817 Picardy in France). 



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

 (Vieillot), Saunders, p. 729. 



* In the Cat. B. Brit. M.U8. this species has been called Procellaria 

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

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

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

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