Coloration. Upper plumage olive-brown, deeply tinged with rufous on the tail and exposed parts of closed wings; ear-coverts and cheeks greyish brown; lores grey; a line commencing above the eye, passing over the ear-coverts and terminating in a broad patch behind them bright rusty ; chin, throat, breast, and abdomen white; sides of breast deep slaty grey streaked with white; the breast with a few small spots of slaty grey; sides of body and the thighs rufous-ashy; under tail-coverts ferruginous.
Bill pale greenish or greyish horny; legs and feet pale silvery-leaden ; iris brown (Hume).
Length about 11; tail 4.5; wing 4.3; tarsus 1.5; bill from gape 1.8.
The young bird wants the bright rusty colour on the side of the head.
There has been a good deal of controversy regarding this bird. After studying the series in the British Museum, consisting of about a dozen skins, I have arrived at the conclusion that P. inglisi is the young bird, and P. hypoleucus the adult. The series contains intermediate .specimens showing a perfect gradation between the two supposed species.
Distribution. Assam from the Daphla hills to Sadiya; the Garo, Khasi, and Naga hills ; Cachar ; Manipur; Arrakan.
