Crown of the head, back of the neck, cheeks and chest emerald-green, which is lightest on the forehead and cheeks; back brownish green; rump scarlet; tip and under surface of the shoulder, spurious wing, and the outer edge of the basal half of the primaries rich ultramarine blue; the blue of the shoulder above passing into sulphur-yellow, and forming a conspicuous spot of the latter colour in the centre of the shoulder; greater and lesser wing-coverts and secondaries bluish green; upper tail-coverts and two centre tail-feathers green, passing into blue towards the tip, which is blackish brown; the remainder of the tail-feathers green at the base, gradually passing into delicate greyish white on the inner webs and the tips; centre of the abdomen yellow; thighs dull bluish green; under tail-coverts greyish white; bill horn-colour; feet brown; irides pale brown.
