Somateria v. nigrum, G. R. Gray, P.Z.S. 1855, p. 212, pl. cvii. ; Elliot, Illustr. Am. B. pl. 48 ; Tacz. F. O. Sib. O. p. 1192 ; Salvadori, Cat. B. Br. Mus. xxvii. p. 430 ; Ridgway, p. 110.
Male ad. (N.W. America). Differs from S. mollissima in having a V-shaped black mark on the throat like S. spectabilis and the bill bright orange or orange-red with the tip paler. Culmen 2.0, wing 12.20, tail 5.5, tarsus 2.15 inch. The female closely resembles that of S. mollissima but is as a rule larger.
Hab. North-west America, east to the Great Slave Lake ; North-east Asia ; the coasts of the Arctic Ocean ; Kamchatka and the Commander Islands.
In habits it is said not to differ from S. mollissima, and its eggs also resemble those of that species, being according to Mr. Nelson light olive-drab, oval in form, and measure from 2.87 by 2.03 to 3.12 by 2.04. Unlike our European Eider, how¬ever, the Pacific Eider does not breed in colonies, but in single pairs, nesting in salt marshes close to a pond or a tide-creek, and not often in close proximity to the sea-shore, and the eggs are deposited in June.
