5. Note on the Petrel named (Estrelata leucopJirys by 

 Captain Hntton. By Sir Walter L. Buller, K.C.M.G., 

 F.R.S., C.M.Z.S., &c. 



[Eeceived August 15, 1894.] 



I am indebted to Captain Hutton for a copy of his paper " On 

 a Collection of Petrels from the Kermadec Islands," which 

 appeared in the ' Proceedings ' of the Zoological Society for last 

 year (see P. Z. S. 1893, p. 749). 



In this paper Captain Hutton describes what he takes to be a 

 new species of Petrel under the name of (Estrelata leucopJirys, as 

 to which I desire to offer one or two observations. But before 

 doing so, I should like to notice another point, although it is of 

 only trivial consequence. It is this : Captain Hutton, in writing 

 of Puffinus chlororhynclius gives the following as a synonym : — 

 " P. carneipes, Cheeseman (fide Buller), Trans. IS". Z. Inst. vol. 

 xxiii. p. 226, not of Gould." Now I should like to know what 

 authority Captain Hutton has for quoting me here. I never saw 

 Mr. Cheeseman's specimen and was never consulted about it. 

 On turning to Mr. Cheeseman's paper, cited above, I find that he 

 says : — " 1 am not quite certain whether this species is correctly 

 identified, all my specimens being fledglings that have not yet lost 

 their down." 



The same remark, as to want of authority, applies to the fol- 

 lowing quotation, as a synonym of (E. nigripmnis, Rothschild : — < 

 " (E. coohii, Cheeseman (fide Buller), Trans. N. Z. Inst. vol. xxiii. 

 p. 224, not of Gray." 



Where Mr. Cheeseman sought my assistance in the identification 

 of species he has mentioned the fact in his paper. 



As to " (Estrelata leucophrys " (of which an excellent figure is 

 given in the ' Proceedings ') I may mention that I took to England 

 with me on my last visit a good series of specimens which I had 

 received from the Kermadec Islands. These I submitted to 

 Mr. Salvin, our acknowledged authority on the Procellariidce, and 

 he unhesitatingly referred them to the highly variable (Estrelata 

 neglecta. At his suggestion I afterwards called at the Zoological 

 Society's rooms to examine the specimen sent home by Captain 

 Hutton, and the type of his new species, of which a drawing was 

 then being prepared for the ' Proceedings.' It was undoubtedly 

 of the same species.
