PLATE CCXXXII. FIG. II. 



Procellaria ~Wilsoni t 



Thalassidroma Wilsoni, TEMMDTCK. 



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 gra>?. 



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



The young are able to go to sea by the beginning of August. 



The egg figured in the plate was lent to me by the Rev. H. B. 

 Tristram, Curate of Castle Eden, Durham. He had it from 

 Newfoundland.
