Coloration. Male above very similar to 0. phayrei, except that the grey of the crown and nape is lighter, french-grey rather than ashy ; the chestnut of the mantle is duller and does not extend on to the wings far beyond the scapulars, most of the smaller coverts being green; the lower back and upper tail-coverts are a more yellow-green than the middle tail-feathers ; beneath there is no orange on the breast, all the lower parts are light yellowish green to the lower abdomen, the feathers of which and of the lower tail-coverts are dark green with yellowish-white tips edged with yellow.
The female, as usual, lacks the maroon on the mantle ; the grey of the cap is generally ill-defined, and passes into green at the sides ; the under tail-coverts as in the male.
