upper parts, and the white mirror was not confined to the 
secondaries, but extended to the primaries, the four or five 
_ external ones excepted. A broad white band of brilliant 
white plumage surrounded the base of the bill. They were 
evidently young birds, and probably all females. 
Two species of scaup are described in De Kay’s Fauna 
of New York; the larger, F. marila, 19 to 19 5 inches in 
length ; and the lesser, /. minor (F. marila, of Audubon), 
17 inches in length, the mirror of which is restricted to the 
secondaries only. - 
Is the female of the larger species, which I consider the 
Bermuda specimens to belong to, so much less than the male ? 
HOoDED MERGANSER (Mergus cucullatus). Col. Drummond 
(late 42nd Highlanders) when stationed at St. George’s, shot 
a merganser on the 23rd of December, 1850, which measured 
nineteen inches in length, and was marked with white on 
each wing. I did not see this specimen, though, from the 
description, there can be no doubt it was the young of the 
Hooded Merganser. 
HORNED GREBE (Podiceps cornutus). On the Ist of Feb- 
ruary, 1855, Captain Tolcher (56th Reget.), presented me 
with a beautiful specimen of this grebe, in spring plumage, 
which he shot near Spanish Point. It was in company with 
three or four others at the time. 
PIED-BILLED DoscHIcK (Podiceps Carolinensis). On the 
18th of November, 1851, I found the perfect skeleton of a 
grebe of this species, on the margin of Chief Justice Butter- 
field’s pond. | 
DOUBLE-CRESTED CoRMORANT (Phalacrocoraxz dilophus). 
In January, 1847, a single cormorant of this species ap- 
peared in the waters of Bermuda, and became the object of
