96 THE NATURALIST, IN BBEMUDA. 



without difficulty, and upon a ledge about half way from 

 the summit, captured two fine specimens of Pupnus 

 ohscurus, the dusky shearwater, of Audubon, one of which 

 was sitting upon a single white egg ; the other had nothing 

 under it. Both these birds were found in holes of the 

 rock, and allowed themselves to be captured by the hand. 

 A young bird of the same species, covered with black 

 down, was also found upon the rock : it was not disturbed. 

 The egg was nearly as large as a common fowl's, but more 

 finely polished on the surface. t 



I carefully examined these specimens, and found the 

 length to be 13^, and 13| inches ; extent, 26 inches. They 

 proved, on dissection, to be a male and female. This dis- 

 covery is highly interesting. The larger species, Piiffinus ■ 

 cinereus, or Wandering Shearwater, of Audubon, is rarely 

 met with in the Bermudas, and certainly does not breed 

 upon their shores. It is, therefore, beyond all doubt that 

 the cahow, described by Governor John Smith, in 1629 ; by 

 Purchas, in 1738 ; and by the native islanders of the present 

 day, is identical with Puffinus obscurus, or the Dusky Shear- 

 water, discovered on the Black Eock, by Captains Orde and 

 McLeod. 



Whether the dusky shearwater continues to frequent 

 the rocky coast of the Bermudas during the winter months, 

 I am unable to state. It is not described by Wilson.
