back, interior scapulars, and primaries, umber-brown; sides of the head, the neck, and crest,
glossed with duck-green: rump and tail coverts, above and below*, with blackish-green.
Lower half of the neck, the breast, shoulders, shorter scapulars, ends of the greater coverts, and
sides of the rump, white ; longer scapulars, striped with berlin-blue, white and blackish-brown.
Lesser coverts berlin-blue. Speculum brilliant grass-green, broadly bordered above and
narrowly edged below with white; bounded interiorly with greenish-black. Belly and flanks
deep orange-brown, the latter undulated posteriorly with black. Bill black. Legs orange.
Form.—Bill a little higher than wide at the base, much depressed, dilated and rounded at
the end. Mandibles furnished with long slender crowded laminae, the upper ones acute
and projecting, forming an apparatus admirably fitted for sifting small insects from the
water. Surface of the upper mandible pitted near its oblong unguis. Wings scarcely
an inch shorter than the tail, which is graduated, moderately acute, and consists of fourteen
acute feathers. Tarsus scarcely compressed. Hind toe not lobed, and the outer toe shorter
than the middle one, as in the rest of the Anatince.
The female is fiver-brown above, with broad borders of pale wood-brown; underneath pale
wood-brown with obscure liver-brown marks. She wants the dark-brown and green colours
of the head, rump, and tail coverts, the white of the neck, breast, sides of the rump, and
scapulars, and also the orange-brown of the belly. The lesser coverts are slightly glossed
with berlin-blue, and the speculum is less vivid than in the male.
