The nesting is performed in burrows, as described, or else the egg is deposited on the ground in 



ti„- aholtoi -I Its or bushes. Usually one egg Is deposited. It is of great size, being two inches and 



three quarters long by one inch and Beven-eighths broad, and snow-white in colour. The albuminous 

 l ,. 1 1 1 \a very large, and il is a strange facl that, no matter how long it is boiled, the yolk and a portion 

 a th< white -till remain soft and watery. 



The young leave the breeding-ground about the end of April, and tor some time after this the 



. i m i| ighbourl I of their birth-places is covered with them for miles. They finally separate into 



Hooka and depart in various directions. 



Th< whole of the plumage a very dark brown, the upper surface darker than the lower; bill, 

 blackish-brown; the under mandible with a longitudinal mark of grey; outer side of the tarsi and outer 

 brownish-black; webs, yellowish flesh-colour, darkening towards the extremities. 



Habitats The numerous islands in Bass's Straits are the particular resorts in summer for the 

 purijos* of breeding and roaring the young; numbers are also met with along the south-eastern seaboard 

 of Nov Zealand, and froqueut thai part of the Pacific lying between that country and the southern 

 portion of tiie Australian continent. 



GENUS PUFFIN US (Brisson). 



f Ml I IS is .in example of the Shearwater. Members of this tribe have of late years been classified into 



J i <• sub-families than formerly. The Mutton-bird, the Fleshy-footed Petrel and others are now 



classed under different species than formerly. The members of these various groups are all gregarious, 

 differing otherwise somewhat in their habits. 



PUFFINUS NUGAX. 



ALLIED PETREL. Genus: Puffinus. 



VTORFOLK [SLAND and parts ol the east coast of Australia are the chief haunts of this variety, 

 1 * where it may be seen in considerable numbers at the breeding season. It is not, however, to be 

 found in such vast flocks as the Mutton-bird. Gould reports that he saw numbers of this Petrel off the 

 north-eastern shores of New Zealand ; he considered this to be the Antipodean representative of the 

 Puffintu Obscunm of Europe. 



The egg is pure white: two inches long by one inch and three lines in breadth. 



Crown of the head, the whole of the upper surface, wings and tail, black: sides of the face,

Total length. 11 inches: bill, 2| inches: wing, 6^ inches; tail, 3 inches; tarsi, lj inch. 



Habitat-: Norfolk Island appears to be the principal breeding place, although met with in 

 considerable numbers on the eastern seaboard of Australia. The vicinity of the Three Kings Islands, 

 oil the northern coast of New Zealand, also seems to be a favourite haunt of this species.
