Note; — In the Suppl. vol. i. p. 112, Buller included 

 (Estrelata incerta with the remark, '* The ' Doubtful Petrel ' 

 having been finally accepted by Mr. Salvin may now be 

 regarded as a valid species. But, apart from this fact, I 

 fear I have nothing to add to its history, no further New 

 Zealand specimens having come to my knowledge." No 

 authentic specimens have ever been procured in New 

 Zealand waters, nor is it likely that any ever will be, seeing 

 that P. incerta Sclilegel is a South Atlantic species with, as 

 far as is yet known, a quite restricted habitat. One of us 

 (Mathews, Birds Austr. vol. ii. pp. 149-151, 1912) has 

 detailed the history of the names P. alba Gmelin and 

 P. sandaliata Solander, and has come to the conclusion that 

 they are both founded on the same specimen and refer to 

 this species; as a consequence, the correct name would be 

 P. alba (Gmelin), but it must be omitted from the New 

 Zealand list, as was pointed out by Finsch (Trans. New 

 Zeal. Inst. vol. vii. 1875, p. 233) almost forty years ago.
