Coloration. Forehead, crown, nape, and hind neck dark olive-brown, an ill-defined but rather broad coronal band pale buff; upper plumage yellowish green; lower part of the rump bright sulphur-yellow; wings dark brown, edged with yellowish green, the greater wing-coverts broadly edged with bright yellow, the median tipped more narrowly and less distinctly; the later quills tipped with yellowish white; the three outer pairs of tail-feathers white, except on the terminal half of the outer webs, which is brown ; the three middle pairs brown, edged with yellowish green; lores and behind the eye dark brown; a distinct supercilium to the nape pale buff; chin, throat, and upper breast grey ; remainder of the lower plumage yellow.
Bill black ; legs dark fleshy brown.
Length nearly 4; tail 1.4; wing 1.9; tarsus .65; bill from gape .4; first primary .5; the second is about equal to the ninth or tenth.
Distribution. The Himalayas, from the Sutlej river to Bhutan. This appears to be a resident species, merely moving vertically according to season.
* However indulgent ornithologists may wish to be to Hodgson, it is, in the ease of this bird, most undesirable to attach the name chloronotus to it. Seebohm has fully stated the case, and so has Hume; and after a personal investigation into the matter I agree with the former and also, I may add, with Brooks in their views of the question.
