General Conclusions. 



Bidweria bulweri breeds in the Pacific as well as in the 

 north Atlantic Ocean. In the Pacific it appears to be 

 confined chiefly to the Hawaiian Islands, another case of 

 somewhat remarkable distribution. 



It will be seen by glancing at the appended schedule that 

 IBulwer's Petrel is not found inhabiting the north Atlantic 

 Islands throughout the year. It appears to arrive at the 

 earliest date in March aud April, more commonly in Mav, 

 and to commence laying early in June, but this varies con- 

 siderably in the different groups of islands. The majority 

 depart at the end of September.
