Irides hazel; feet dull grey, front of tarsi and toes blackish, polished; beak grey, blackish at tip, tinged with flesh-colour at base; tongue ending in a long horny point; no naked skin on head. General plumage brown, each feather marked through the centre with a pointed pencil of pure white. On the crown the hue is dusky, the centres being merely paler; on the neck the centres are large, and give the prevailing hue; it is on the fore-back and wing-coverts that the centres assume their beautiful form and distinctness. The quills, greater coverts, loins, rump, and tail, are destitute of white centres. On the inner wing-coverts, the breast, belly, and thighs, the brown is dull, and the centres large and well marked; the edges of the feathers loosely webbed. On the cheeks, the markings pale and indistinct; chin impure white. The brown of the back, wings, and tail is of an exceedingly rich deep hue, very silky, and displaying an iridescent glow of purple, like that of shaded silk. Wings short, third, fourth, fifth, and sixth quills, equal. First quill short, sickle-shaped; the outer web attenuated, and the inner dilated, towards the point. Tail broad, rounded, of twelve feathers. Under tail-coverts, large, nearly reaching the tip. Claws obtuse. Beak slender, upper mandible curved, blunt at tip; lower mandible straight; both rounded at edges; the rami of the lower soldered together at about half the length, where the cavity is nearly obliterated. The mandibles do not close accurately. Nostrils perforate.
