CLANGULA ALBEOLA.—C. ISLANDICA. 609 
generally very similar to that of the Pintail. “ From personal observation,” 
he goes on to say, “ I have come to the conclusion that the usual quantity of 
down necessary for a duck’s nest is seldom met with before a full set of eggs 
has been deposited, and that the process of lining with down, which is plucked 
off from the body of the female, goes on simultaneously with their laying.” 
CLANGULA ALBEOLA (Linnzus). 
BUFFEL-HEADED DUCK. 
[§ 5821. One.—Fort Yukon, Alaska. From the Smithsonian 
Institution, through Professor Baird, 1870. 
The ticket shews that it was one of nine, obtained as above with the 
parent (no. 49868) by Mr. J. McDougal, the chief officer of the Hudson’s Bay 
Company’s post there. Mr. Dall says (Trans. Chicago Acad. Sc. i. p. 298) the 
bird is “not uncommon on the Yukon, where it breeds,” and “abundant at 
the Yukon mouth, where there are no trees, except scrubby willow and alder, 
and probably breeds there.” (Cf. Proc. Zool. Soc. 1871, p. 57.) | 
CLANGULA ISLANDICA (Gmelin). 
BARROW’S GOLDENEYE. 
§ 5822. One.—Iceland. From Mr. Hewitson, 1844.

[§ 5826. Zhree—Myvatn, 10 July, 1862. “G.G. F.” 
Given to me by Mr. G. G. Fowler, of Gunton Hall, near Lowestoft, and 
obtained by him during his late visit to Iceland in company with Mr. Shepherd 
but I do not think the eges were actually taken by either of these gentlemen. }
