1607. Nyroca baeri.

The Eastern White-eyed Duck.

Anas (Fuligula) baeri, Badde, Reis. S.O. Sibir. ii, p. 376, pi. 15 (1863). Nyroca baeri, Salvadori, Cat. B. M. xxvii, p. 344. Fuligula baeri, F. Finn, P. A. S. B. 1896, p. 61; id. J, A. S. B. lxvi, pt. 2, p. 525 ; Sclater, P. Z. S. 1896, p. 780.

This Duck is a very near ally of N. ferruginea, but is distinguished by both sexes having the head and neck black, glossed with green in the male, but brownish and with very little gloss in the female, in which sex also the lores are rufous-brown. The basal portion of the primaries, too, in the present species is light greyish brown, not white. In other respects the two species are similar, there is the same white speculum on the secondaries, and the same sharp division between the chestnut breast and white abdomen in the male, whilst the two pass into each other in the female.

Bill bluish, the base and nail black ; irides white or pale yellow ; feet lead-grey (David).

Length 18 ; tail 2.4 ; wing 8.25 ; tarsus 1.3 ; bill from gape 2.

Distribution. Eastern Siberia, China, and Japan. Although specimens appear to have been obtained in Bengal by Duvaucel, the occurrence of this Pochard in India had been completely overlooked until Mr. Frank Finn, in February 1896, obtained several specimens in the Calcutta bazaar and identified them. He then, on examining the specimens of Fuligula nyroca collected by Mr. Blyth, found that one of them, which had been in the Asiatic Society's Museum since 1842, was a female of N. baeri. I learn from Mr. Finn that in the present year (1897) this Duck has again been obtained commonly in Calcutta, so it is probable that this species has hitherto been confounded with the nearly allied N. ferruginea.
