This bird was likewise found breeding in great numbers during 

 the months of November and December. The mode of nidification 

 is so precisely similar to that of P. sphenurus, Gould, that a 

 sejiarate description is not necessary. Like all Petrel's eggs they 

 ,are white and have a peculiar musky odour, which they always 

 retain, even when empted of their contents and ,kept for many 

 years. Only one egg is laid for a sitting j six specimens measure 

 as follows :— length (A) 2-63 x 1-78 inches ; (B) 2-8 x 1-73 inches; 

 (0) 2-78 x 1-8 inches; (D) 2'65 x 1-81 inches; (E) 2-82 x 1-72
