This has been one of the species doubtfully attributed to the Californian coast, the 

 occurrence of which has only recently received verificat^^ion. It had not been met witii 

 there by Dr. Cooper, and until identitied by Mi: Ileiisliaw, there was no satisfactory 

 evidence in support of its claim to a place in the fauna of North America, lint little 

 is known as to its habits, its distribution, or the places to which it resorts for breed- 

 ing. Mr. Henshaw states that I'etrels appear to be (juite nununous along the entire 

 coast of California. He received an example of this species from Captain Forney, who 

 had procured it on San Miguel, where it was said to be breeding in great miu)ber,s. 

 As usual with this family, it was nesting in bui-rows.
