A specimen in Mr. Bartram’s collection, captured while sitting on its 
solitary egg ina rocky hole on a small island in Castle Harbor, in 
April, 1864. The egg was unfortunately broken. There is no record of 
the bird’s breeding on any other occasion, nor of any other specimens 
being obtained; but it is quite possible that it, as well as Wilson’s Pe- 
trel and other Procellaride, may formerly have frequented the islands 
in numbers, and that an occasional pair may revisit their old haunts. 
Such birds would, from their habits, be but little noticed by any but 
fishermen.

Since Mr. Hurdis, in 1849, identified the “‘Cahow” or “ Cowhow” of 
the historians of Bermuda with this interesting species, very few ob- 
servations have been made on the few pairs still frequenting the islands. 
That the poor ‘‘Cahow” has almost ceased to breed there is a melan- 
choly fact. Formerly it was plentiful, and even within the last fifteen 
years, Mr. Bartram informs me, there were many nests in the isolated 
rocks, both on the north and south shores. On the north side the bird 
was formerly called ‘“‘ Pemblyco” or “ Pimlico,” probably from its call- 
note, while on the southern shores the name ‘‘ Cahow” or “‘ Cowhow” 
was applied to it. I found two nests in 1874, each containing a single 
young bird, one of which I kept alive for about six weeks, intending to 
send him to the Zoological Society’s Gardens in London; but before I
