BIRDS OF BERMUDA. 257 
Hab.—North America, especially United States; breeding throughout 
in suitable places, and wintering chiefly in the south; Cuba (Coues). 
‘A female bird of this species was shot by Dr. Cole, Twentieth Regi- 
ment, on the 16th December, 1846” (Nat. in B., p. 48). 
Sub-family FULIGULIN Ai.

Length, 16.50; wing, 8; tarsus, 1.34. 
Hab.—The whole of North America, and south to Guatemala in 
winter; part of the West Indies (Coues). 
To make matters clear, in treating of this species, I must call in the 
aid of Dr. Coues, who says, in his “Birds of the Northwest” (p. 574): 
“Authors are at variance concerning the relationship of the bird to the 
preceding (f. marila), and the question is not yet settled. For myself 
I am rather inclined to keep the two apart, notwithstanding their very 
close resemblance, and admitting the probability that intermediate ex- 
amples may be found. There appears to be something different in their 
range, the F’. affinis being the more southerly. Not that it does not in 
the breeding season reach as high latitudes as the other, but that its 
autumnal movement is pushed to the West Indies and Central America, 
where the true F. marila is not recorded as occurring. It is improbable 
that two varieties, if they be really such, should preserve this differ- 
ence.” Armed with this authority, I think I may safely refer the speci- 
mens of the Scaup chronicled in “The Naturalist in Bermuda,” all of 
which measured only 16 to 164 inches in length, to this smaller species, 
F. affinis. The length of F. marila varies from 19 to 205 inches. The 
specimens alluded to are one killed by Mr. C. Abbott, Twentieth Regi- 
ment, on the 19th December, 1846, and two others by Colonel Wedder- 
burn, at Warwick Pond, on the 8th January, 1849. Lieutenant Deni- 
son, Royal Engineers, shot a female specimen at Tucker’s Town on the 
25th February, 1876, measuring 16 inches in length.
