96 THE NATURALIST IN BERMUDA. 
without difficulty, and upon a ledge about half way from 
the summit, captured two fine specimens of Puffinus 
obscurus, 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. 
I carefully examined these specimens, and found the 
length to be 134, 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, Pufinus 
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 Pujinus obscwrus, or the Dusky Shear- 
water, discovered on the Black Rock, by Captains Orde and 
McLeod. | 
Whether the dusky shearwater continues to frequent 
the rocky coast of the Bermudas during the winter months, 
IT am unable to state. It is not described by Wilson.
