Description of adult male. 
Colour. — Entire dorsal aspect umber brown: base of feathers on hind part of 
neck, white ; base of those on back, irregularly banded with pale fulvous, and 
the scapulars with a distinct band of it. The inferior feathers of upper tail co- 
verts banded in like manner to their extremities. Tail dusky clove-brown, 
obscurely marked with darkened transverse narrow bands. Primaries per- 
fectly black towards their extremities, but with the outer edge of their base, 
gray : inner web banded and freckled with gray, brown, and white, which in 
the secondaries takes the form of regular bars. Under surface, entirely umber 
brown, but rather paler than the upper. Lining of wings gray, with irregular 
transverse brown bars : under-side of tail the same, but paler. Thighs of a 
rather yellower brown. Bill and cere horn colour, mottled with pale gray : 
tarsi yellow. 
Form. — Beak, with apex much arched, both longer and more pointed than it is 
in the group of the Polyborince. Cere naked, with few bristles ; nostrils large, 
quite uncovered, irregularly triangular, with the angles much rounded, and 
situated rather above a central line between the culmen and commissure. 
Fourth primary longest, but third and fifth nearly equal to it ; first, four 
inches and a half shorter than fourth, and equal to the eighth; second shorter 
than fifth. Extremities of wing reaching within half an inch of end of tail
