which it diEEers much ia the stoutness of the bill and in the 

 colours of the feet, as well as in the plumage. From (E. leuco- 

 ptera it differs in being lighter in colour and in the outer tail- 

 feathers having the inner web white at the base and speckled with 

 grey at the tip. 



" jVot uncommon diu-ing the summer months, arriving about 

 the beginning of ^November and leaving again at the end of April. 

 It breeds on Meyer Island and more sparingly on Sunday Island, 

 generally in company with P. assimills. It constructs a burrow 

 sometimes over a yard in length, depositing a single pure white 

 egg at the extremity." (Cheeseman.)

 regions, neck all round, breast, abdomen, and crissum pure white. 

 Under wing-coverts -nhite, with a dark patch inside the wTist- 

 joint. Back sooty black ; between the shoulders the feathers are 

 largely tipped with grey, which gets less and less and disappears 

 on the uropygium. The anterior part of the back is entirely grey, 

 and this colour extends slightly on to the breast on each side, but 

 not below the wings when folded. Some of the feathers of the 

 flanks are tipped with grey or blackish. Upper taU-coverts 

 brownish grey. Tail-feathers brownish grey, white at the base;

 in the adult. On the other hand the yeUow of the feet and tarsi 

 is much darker. The measurements of the two are much the same. 



I have to thank Mr. O. Sahin for identifying this bird. I have 

 not seen his description in ' The Ibis.' 



" It arrives about the end of September and remains until the 

 end of June, being one of the last Petrels to leave the island. It 

 is solitary in its habits, and very seldom can two nests be found in
