The Wedge- tailed Petrel breeds on Nepean Island, which is so 

 honeycombed that it is dangerous to walk over some parts, the 

 thin crusts over the burrows being insufficient to support one's 

 weight. The northern slopes of Phillip Island are similarly 

 riddled, and many birds breed in the shallow holes drilled in the 

 slight soil covering the rocky islets to the north of the main 

 island. I found a pair preparing their burrow on the Redstone 

 in October, 1908. 



At Lord Howe Island it breeds on Goat Island in the Lagoon, 

 Mutton Bird Island, and on the Admiralty Islets. Although I 

 was too early to find any eggs, I surprised some birds in the act 

 of clearing out the old burrows preparatory to laying. 



I received several eggs from Mrs. Nichols taken in December, 

 1907. Dimensions: («)2-5xl-66; (6)2-25 x 1-58(L.H.L, Dec, 

 1907). 



Sir Walter Buller expressed the opinion that Dr. Crowfoot's 

 P. sphenu7'us is P. griseus. Crowfoot gave the dimensions of 

 eggs of P. sphenurus as varying from 2*5 to 2*75 inches in length, 

 and from 1-5 to 1'75 inches in breadth. These dimensions are 

 sufficiently wide to embrace both species.
