Saunders, Manual Br. B. ed. ii. p. 734 (1899).

This interesting little Petrel was first described by the late Mr. E. Vernon Harcourt in 

 1851 under the name of Tkalassidroma castro, but was entirely lost sight of till it was again 

 described by Mr. Ridgway in 1882 as Oceanodroma cryptoleucura. It has an immense 

 range, specimens being on record from Niibau, Sandwich Islands, Madeira and surrounding 

 islets, Cape Verde Islands, St. Helena, the Galapagos Islands, Washington City (picked up), 

 Drogden lightship off Copenhagen, Kobbergrunden in the Kattegat, and lastly one picked 

 up dead at Littlestone, Kent, in December 1895. 



In Part I. of this book there is a printer's error, the wing measurement beind given 

 as 575 to 8*3 instead of 63 inches. 



87. BULWERIA ANJINHO {Eeineken). 



Antea, Pt. I. p. 51 (sub nomine B. bulweri) ; Salvin, Cat. B. Brit. Mus. xxv. p. 420 (1896) {B buhveri). 

 Knudsen obtained this bird on Kauai. 



8b. PUFFINUS CUNEATUS, Salvin. 



Antea, Pt. I. p. 47 (1893); Salvin, Cat. B. Brit. Mus. xxv. p. 371 (189(3) ; Anthony, Auk, 1898, pp. 39, 313, 

 316 (San Benedicte and Socorro Islands). 



This Petrel is only known in the Sandwich group from Kauai, where it was procured by 

 Mr. Knudsen. Palmer only sent specimens from the Laysan group. 



Professor Schauinsland's Laysan series consists of adult birds of the phase with white 

 under surface, and young in down. The latter are pale grey, lighter and almost white on the 

 neck, breast, and middle of abdomen. The feet, according to Schauinsland, are bluish white 

 or whitish grey (not yellow or red !) ; the bill grey with black tip. 



In Part I. of this work I stated that the underparts were brownish grey in the young. 

 I find, however, from the observations of Mr. A. W. Anthony on Socorro and San Benedicte 

 islands, that these entirely grey birds are not necessarily young, but represent a regular 

 phase of plumage, found also in other species of Petrels and also in the Skuas. 



Mr. Anthony found on the above-named islands that the dark birds outnumbered the 

 light by two to one; while on Laysan, in a series of at least fifteen skins, not one dark bird 

 was found, and the only specimens with dark underside I possess from this region were 

 procured by Palmer on French Frigate shoals. I possess also two specimens with white under 

 surface from the Bonin Islands.
