distinct species under the name melanogaster, though other authors 

 have regarded these names as s^aionymous. Mathews ranks 

 melanogaster as a sub-species of tropica, and has named the New 

 Zealand race F. t. australis. This is the form that occurs in 

 AustraHan seas. 



[Fregetta leucogaster (Gould). White-bellied Storm-Petrel. 



This species has commonly been regarded as the same as F. 

 grallaria, but Mathews shows that it is distinct (7, p. 42). 



The type locality is the South Atlantic, and there are two 

 specimens in the British Museum, labelled as froni South Aus- 

 tralia, presented by Sir George Grey. No doubt these were 

 collected on one of Grey's voyages.] 

 Fregetta tuhulata (Mathews) (7, p. 42). 



A specimen killed near the coast of Australia on a voyage to 

 Sydney, by a Mr. Denison, who presented it to Gould, is in the 

 British Museum. There seems no reason to doubt its authenticity, 

 and Mathews has described it under the manuscript name which 

 Gould had written on the label. No other known bird agrees with 

 it. 



Sub-genus Frcgcttornis. 

 Fregetta grallaria (Vieillot). White-bellied or White-breasted 

 Storm-Petrel. 



Mathews records a specimen obtained in lat. 35° S. long. 158^ 5' 

 E. — a locality practically equidistant from Australia and Lord 

 Howe Island (7, p. 40). He states that the bird agrees with the 

 type in the Paris Museum, which is said to have come from 

 Australia. 



Family PROCELLARHD.E. 



This is the family generally known as Pitfinida;, but, as has 

 been noted above, it includes Procellaria, the oldest Petrel genus, 

 from which, therefore, it should take its name. 



Genus Puffinus — Shearwaters or Mutton-Birds. 



Sub-genus Alphapitffinits. 



Piifinus assimilis (Gould). Allied or Gould Petrel or Shearwater. 



This species breeds on the Houtman's Abrolhos Islands, off the 

 west coast of Western Australia, and in the Recherche Archi- 

 pelago, off the south coast. Specimens are in the Western 

 Australian Museum, obtained on the beach at Cottesloe, near 

 Fremantlc. 



The type locality of the species is Norfolk Island, and the 

 typical form may be expected to occur on the East Australian 

 CJast ; but at present there is no record of its having done so. 

 The West Australian form has been separated by Mathews as 

 P. a. tiinneyi. 



[Piiffnuis Iheriiiinicri (Lesson). Black-and-White Petrel or Shear- 

 water. 

 Mathews considers that a bird obtained by Solander on 6th 

 June, 1770, off the Queensland coast, and described in his manu-
