I have in this paper adhered to the " Check-list " nomen- 

 clature, but in describing the two birds found on the Brush Island 

 trip * 1 followed Mathews's " Hand-list " for the new sub-species 

 of the Short-tailed Petrel, and ventured to place the " Fluttering " 

 Petrel in a new genus, thus departing from the principles of the 

 " Check-list," but following Mathews. Possibly, when the new 

 " Check-list " is prepared, and further investigation reveals more 

 of the life-history and habits of the Fluttering Petrel, some altera- 

 tion may be necessary. I here take the opportunity of correcting 

 an error in the generic characters of Cinathisnta cyaneoleuca. 

 The number of rectrices should be 12. 



It is somewhat remarkable that we should have encountered 

 such large numbers of the Fluttering Petrel, in view of the fact 

 that Puffinus gavia {Reinholdia reinholdi hyroni, Mathews) is con- 

 sidered to be a very rare bird indeed, and the two white-breasted 

 birds might easily be taken for the one species by superficial 

 observers. The records of occurrence of P. gavia are four only, 

 — the first l)eing a h\dng bird, picked up after a storm at Victoria 

 Park, Sydney, by Professor Anderson Stuart, and by him presented 

 to the British Museum ;t the second was picked up dead on 

 Bondi beach by Mr. William Barnes, after an easterly gale, in 

 September, 1908,$ the skin of which was exhibited at a meeting of 

 the Linnean Society, of New South Wales, by North, in 1909 ; the 

 third was Mathews's type, which, I understand, was also picked 

 up dead on one of the northern rivers ; while the fourth occur- 

 rence was the specimen found by Rohu at the Five Islands 

 (see ante). 



By the courtesy of Mr. Sylvester E. Rohu I am enabled to add 

 to this paper a transcript of some notes compiled from observa- 

 tions taken over a period of eighteen months — ^April, 1913, to 

 September, 1914 — by Messrs. E. A. Windle and W. Newton, 

 fishermen working between Broken Bay and Botany Bay, New 

 South Wales, and Mr. Rohu. These notes are of great value as 

 showing the periods of greatest frequency of the species mentioned 

 within the area in question, and throw valuable light on the 

 problems connected with their breeding seasons. The nomen- 

 clature is that adopted by Mr. Rohu, and it is only necessary to 

 suggest that the " Puffinus assimilis " mentioned in the list 

 })robably refers to both of the white-breasted Petrels — Reinholdia 

 reinholdi hyroni, Mathews, and Cinathisma cyaneoleuca, Hull.
