WILSON'S PETREL. 



PLATE CCXXXIl. FIG. II. 



Procellaria Wilsoni, .... Jentns. 



TJialassidroma Wilsoni, .... Temminck. 



These birds appear to build in numbers, about the 

 beginning of June, on sandy islands, in which they 

 burrow small holes to the depth of two feet or two and 

 a half: the necessary bedding provided is a little grass. 



The egg is a single one, and its colour white. 



The young are able to go to sea by the beginning 

 of August. 



The e^^ figured in the plate was lent to me by the 

 Rev. H. B. Tristram, Curate of Castle Eden, Durham. 

 He had it from Newfoundland.
