Genus PTERODROMA, Bonaparte. 



Of this genus, which is intended to comprise the nearly 

 uniformly coloured black Petrels of the Southern Ocean, there 

 are at least three species which frequent the Australian seas, 

 and which I believe are correctly named in the succeeding 

 descriptions. 



Sp. 627. PTERODROMA MACROPTERA. 

 Great Winged Petrel. 



Procellaria macroptera, Smith, Zool. of South Africa, Aves, pi. 52. 



brevii'oatris, Less. 



Ossifraga macroptera, Reichenb. 



Pterudroma macroptei-a, Bonap. Consp. Gen. Av., torn. ii. p. 191, 

 Fterodroma, sp. 1. 



I consider a bird I killed over the seas surrounding Tas- 

 mania, where it was tolerably abundant, and which differs 

 from the next species in being of a larger size, having much 

 longer wings and a greyer face, to be identical with the P. 

 macroptera of Smith, and I therefore retain it under that 

 appellation, in preference to assigning it a new name. 



" This bird, when on the wing," says Capt. Hutton, " looks 

 very like a huge Swift. R is not by any means common, and 

 I have only seen it east of the Cape of Good Hope. R is not 

 found on Prince Edward Islands nor Kerguelen's Land." — 

 Ibis, 1865, p. 286. 



Sp. 628. PTERODROMA ATLANTICA, Gould. 

 Atlantic Petrel.
