TRANSACTIONS OF THE 
14:7» Mareca americana Steph. (585.) BaUlpate. Not uncom- 
mon near Nulato and on the Yukon. Rather rare at St. Michael's. 
Eggs and nest resemble those of Dajila acuta, but the bird is less active 
and slower in flight than tliM species. D. 
148. Chaulelasmus streperus Gray. (584.) Gadwall. One speci- 
men was obtained in British Columbia by Mr. Elliott, and it is probable 
that its range extends to the vicinity of Sitka. D. 
149. Fulix marila Baird. (588.) Gogle (Rus.). Greater Blackhead. 
Abundant at Sitka, where it was plentifully obtained by Bischoff. One 
of the first ducks to arrive, and common on the Yukon and the seacoast. 
I obtained the eggs at the mouth of the Yukon in the early part of June. 
Nest very rude, a mere excavation with a few straws about it. Poor 
eating, usually tough and lean. D. 
150. Fulix afflnis Baird. (589.) Little Blackhead. Not uncommon 
at the Yukon mouth, where the eggs were obtained. D. 
151. Aythya vallisneria Bon. (592.) Canvas-back Duck. Quite 
common at Fort Yukon, where it breeds in abundance. I have never 
seen it southwest of that point on the Yukon. D. 
152. Bucephala americana Baird. (593.) Golden-eye. This was 
the first duck killed at Nulato, May 3rd, 1868, and is always early in 
arriving. It is common on the Yukon and on the seacoast. The ogiis 
were obtained near Pastolik, from the marshes. A skin of this duck, 
stufied and ornamented with beads, used as an ornament in the lodge, 
was bought from some Indians on the Yukon, near the Mission. D. 
153. Bucephala islandica Baird. (594.) Barrow's Golden -eye. 
Obtained by Bischoff at Sitka, and rarely on the Yukon. D. 
154. Bucephala alheola Baird. (595.) Batter Ball. Not uncom- 
mon on the Yukon, where it breeds. It is abundant at the Yukon 
mouth, where there are no trees, except scrubby willow and alder, and 
probably breeds there. Obtained by Bischoff at Sitka. D. 
155. Histrionicus torquatus Bon. (596.) Obtained at Sitka and 
Kadiak by Bischoff. Rather rare in the vicinity of the Yukon. This is 
an essentially solitary species, found alone or in pairs, only in the most 
retired spots, on the small rivers flowing into the Yukon, where it breeds ; 
and not, except accidentally, on the main river. D. 
156. Harelda glacialis Leach. (597.) Safka (Rus.). Old Squaw. 
Very common at St. Michael's ; was one of the last ducks to leave in 
the fall of 1865. B. 
An extremely common duck on the seacoast, but very rare on the 
Yukon. One specimen was killed June 1st, 1868, at Nulato, while the
