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 
separate 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 ; six specimens measure 
as follows :—length (A) 2-G3 x 1-78 inches ; (B) 2-8 x 1-73 inches; 
(0) 2-78 x 1-8 inches ; (D) 2-Go x 1-81 inches; (E) 2-82 x L72 
inches; (E) 2-87 x 1-81 inches.

This bird is found breeding during November and December, 
its single egg is laid under the shelter of projecting ledges, of 
almost inaccessible rocks, on the face of cliffs, and are consequently 
very difficult to procure. The eggs are oval in form, being thickest 
at the centre and tapering slightly at one end, of a dull reddish- 
brown colour, which is nearly obscured by minute freckles and 
spots of purplish-brown and grey, in some instances they are 
blotched and smeared, not unfrequently on the smaller end. Two
