_Description of Adult Male_ (type).--Throat, upper breast, lores
and forehead glossy wall-green, in certain lights with violet
reflections; upper tail-coverts much the same, but nape and back
brilliant peacock-green. Lower breast, sides, belly, and under
tail-coverts bright scarlet-red; feathering of legs dusky, with
faint green gloss and slightly bordered with whitish. Primaries
fuscous-black, the outer ones margined with white and the inner
ones white at the base. Alula and primary-coverts blackish;
lesser wing-coverts blackish, broadly margined with green; middle
coverts with less green and vermiculated with white. Greater
coverts and secondaries blackish vermiculated with white, the
former narrowly edged with green, the secondaries only very
faintly. Three middle pairs of rectrices blackish, slightly
glossed with violet-blue and margined with green; outer three
pairs white, with bases black faintly glossed with blue, this
blackish color extending out furthest on inner webs, and finally
breaking up into small dusky spots.

Iris red-brown; distal portion of bill light greenish gray, base
of bill and two naked patches beneath eye light cadmium-yellow,
naked skin above eye lemon-yellow; bare skin of foreneck (covered
in life by plumage) light blue; feet pale pink.

Length (skin) 254 mm.; length of bill (culmen from base) 18 mm.;
height of bill at nostril 9.5 mm.; greatest width of maxilla, near
gape, 16 mm.; wing (measured with dividers) 113 mm.; tail 146 mm.

In some of the other male specimens the green borders on the
secondaries are lacking, and the exact intensity of the white
vermiculation is of course variable. The measurements of a series
of 11 adult males are: bill, 17-18.5 mm.; wing, 108-115.5; tail,
136.5-151. This is smaller than any _Apaloderma_ heretofore
described.

_Adult Female._ Crown, back, and rump brilliant peacock-green,
upper tail-coverts viridian. Lores, forehead, and ear-coverts
more brownish; throat and upper breast snuff-brown, sometimes
with
