GREATER SHEARWATER. 653 



with dull white and ash brown ; legs, toes, and their mem,- 

 branes, brownish-yellow. The whole length is eighteen 

 inches ; of the wing, from the bend, thirteen inches ; whole 

 length of the bill one inch and seven-eighths ; of the tubular 

 portion half an inch ; of the tarsus two inches and one- 

 eighth ; of the middle toe and claw two inches and seven- 

 eighths. 



The egg is very large, but only one is produced. Two 

 specimens in my own collection measure two inches and 

 three-quarters in length by one inch and seven-eighths in 

 breadth, each ; the colour pure white when first deposited, 

 becoming soiled as incubation progresses. 



There are specimens in the British Museum from South 

 Africa, and known to be the young and adult of the same 

 species, which exactly resemble the two birds here figured. 



M. Temminck says this species breeds by thousands on 

 the banks of Newfoundland. It is probably the Wander- 

 ing Shearwater of Messrs. Audubon and Nuttall.
