Coloration. Very similar to O. penicillata, but differing in having the white of the throat passing under the cheeks and ear-coverts and merging into the pale colour of the side of the neck, thus isolating the black on the fore neck and upper breast; the present species is also much larger and the feathers of the upper surface have, in the worn summer plumage, very much larger and more conspicuous dark shaft-streaks. The pale parts of the head are at all seasons white, never yellow.
The colours of the soft parts of this Lark do not appear to have been recorded.
Length about 8.5 ; tail 3.7 ; wing 5 ; tarsus .95; bill from gape .8 ; bill at front .55 to .6.
Distribution. The higher parts of the Himalayas from Kashmir and Ladak down to Kumaun, extending into the adjoining parts of Tibet. This species appears to be found only at very high altitudes.
