Vernacular names. Do-di (Tibetan); Pegam-bejee (Gyantse).
Description. - Male. Differs from P. p. pulcherrimus in having the lores, cheeks, forehead and ear-coverts glistening rosy-red with no black marks showing; the crown is far more suffused with rosy ; the rump-band seems wider and the upper plumage is more ashy, less rufous.
Colours of soft parts. " Iris rosy-brown ; bill horny-brown, the lower mandible greyish; the feet rosy-grey " (David).
Measurements. About the same as in the preceding bird. "Wing 72 to 84 mm.

Distribution. Eastern Tibet, Bhutan, Hills North of Brahmaputra, Yunnan and China from Szechuan to Tsinling and Shensi. I cannot separate Sharpe's Propasser p. waltoni from P. p. davidianus, which latter form was practically unrepresented in the British Museum when Sharpe named waltoni.
