Adult.—Upper parts dark brown; nearly black on head, neck, and back 
which have a faint green gloss; feathers of rump and upper tail-coverts 
lighter brown and narrowly fringed with gray in unworn plumage, the 
tail-coverts with dark shafts; wing-feathers blackish brown, glossy on 
outer webs; short primaries narrowly edged with white on inner webs; 
tail of the same color as wings; sides of head brown; chin and throat 
light drab-gray, merging gradually into the dark drab-gray of the lower 
breast and abdomen where the feathers are narrowly edged with whitish ; 
stiff feathers in front of eye white with brown tips. Length in flesh, 
114; wing, 119; lateral rectrices, 50; central rectrices, 31. 
This species is easily recognized by the deeply-forked tail and peculiar 
paired toes; it is a near relative of Tachornis infumata from which it 
differs chiefly in having a paler chin and throat. It has been found in 
small numbers in the islands from which it is recorded.
