710. Cinclus pallasi.
Cinclus pallasii, Temm. Man. d'Orn. ed. 2, i, p. 177 (1820); Salvin, Ibis, 1867, p. 118; Hume, S. F. vii, p. 378 ; id, Cat. no. 349 bis; Sharpe, Cat. B. M. vi, p. 316; Hume, S. F. xi, p. 124.
Coloration. The whole plumage with the lesser wing-coverts a very rich dark chocolate-brown ; the eyelids clothed with white feathers; the abdomen blackish ; greater wing-coverts dark brown, edged with chocolate-brown ; wings and tail blackish, suffused with chocolate-brown on the outer webs.
The young differ markedly from those of C. asiaticus. The whole upper plumage and the sides of the head and neck are blackish brown with subterminal rufous margins; the wings and coverts with white, or on some of the feathers slightly rufous, edges ; tail black, narrowly tipped with white; the whole lower plumage blackish brown, with ashy fringes to all the feathers.
Another bird, which has just completed its first autumn moult, resembles the adult, but the throat, breast, and middle of the abdomen are mottled with white and the wings retain their white edges.
Iris hazel; bill horny; legs plumbeous in front, dusky behind (Cockburn).
Length about 8; tail 2.1; wing 3.9 ; tarsus 1.15; bill from gape 1.15.
Distribution. In the British Museum there is an adult procured by Cockburn at Shillong and two young birds obtained by A. W. Chennell in the North Khasi hills. The latter were shot in March and are those described above. In the collection of Godwin-Austen are three specimens of this species, two adults, procured at Shillong in April and May respectively, and a young bird procured in North Cachar without date. I have seen no other specimens from Indian limits. This species is found in China and the whole of North-eastern Asia.
