Marila marila (Linnaeus). Scaup Duck. 
A greater scaup duck was shot at Windfall Harbor, Admir- 
alty Island, April 22, but was not preserved. Others were seen 
there almost daily. Littlejohn records that at Glacier Bay a 
large flock was frequently seen about the narrow channels among 
the small islands. They were not paired, and showed no indica- 
tions of breeding. 
Marila affinis (Eyton). Lesser Scaup Duck. 
This species was met with only at Glacier Bay, where at the 
edge of a small pond on one of the islands Littlejohn found a 
set of ten eggs, July 16. The nest was placed within a heavy 
growth of grass about a foot from the water’s edge, and con- 
sisted of grass stems lined with a little down from the parent’s 
breast. Although the eges were almost on the point of hatching, 
they were brought home and later successfully prepared. They 
are plain olive-buff in color. <A selected average egg measures 
59.7 * 40.4. The female was shot as she left the nest and is 
No. 91 of the University collection. Stephens saw another fe- 
male with a brood of young. This is the first breeding record of 
M. affinis that I know of for Alaska. 
Clangula clangula americana Bonaparte. 
American Golden-eye. 
A golden-eye thought to be of this species was found only on 
and about Admiralty Island, where it was seen oceupying about 
the same loealities as the American merganser. At Windfall and 
Mole harbors, and about the lakes inland from the latter place, 
the species was noted more or less commonly. Both Littlejohn 
and Dixon believed it to be breeding in the region, but neither 
eggs nor young were discovered. No skins of this duck were 
obtained. 
Charitonetta albeola (Linnaeus). Buffle-head. 
_ At Windfall Harbor, Admiralty Island, buffle-heads were 
rather common. for a little while during the last of April and 
early May. A female specimen (No. 70) was preserved. The 
species was met with nowhere else.
