MONOGRAPH OF THE PETRELS. 



volume of Gould's " Birds of Australia," where he figures a pale bird of P. chlororhynchus, 

 which appears to answer to the white-breasted phase of P. cuneatus. Gould supposed 

 that this was the young of P. chlororhynchus, but I have never seen an Australian 

 bird corresponding with his figure. If it should be proved that P. chlororhynchus 

 has a light-breasted phase, I do not see how P. cuneatus can be upheld as a species. 



It is possible that the colour of the bill and feet may distinguish the birds in life, 

 but with regard to this point there is not much definite information. 



According to Mr. Seebohm (Ibis, 1891, p. 191,) the late P. A. Hoist gave the soft 

 parts of P. cuneatus from the Sulphur Islands as follows : — " Bill light grey with a 

 black hook : tarsi and feet pale pink." Hoist was a Swede, and wrote very fair 

 English, and I have given above the note on his original label, which Mr. Seebohm 

 has paraphrased. 



Professor Schauinsland says that the colour of the bill in Laysan specimens is grey, 

 with a black tip, and the feet bluish-white or whitish-grey, not yellow or red (c/. 

 Rothschild, Avif. Laysan, II., p. 287). 



My description and figure are taken from the type in the British Museum.
