In the adult nude the general colour of the upper parts is chocolate- 

 brown, somewhat darker on the head, and shading into slate-brown on 

 the rump and into slate-grey on the upper tail-coverts ; lores and ear- 

 coverts dark brown ; no trace of ej'e-stripe ; wings brown ; wing- 

 coverts, outer webs of innermost secondaries, and unemargiuatcd por- 

 tion of outer webs of quills russet-brown ; tail brown. Chin white ; 

 cheeks and upper throat white, each feather having a fan-shaped dark- 

 brown terminal spot ; lower throat white ; breast pale slate-grej', 

 somewhat darker on the flanks, and shading into nearly white on 

 the centre of the belly and into pure white on the under tail-coverts ; 

 axilhiries and under wing-coverts pale slate-grey, obscurely mar- 

 gined with white ; inner margin of quills pale brown. Bill dark

The female does not differ from the male. Examples from 

 Tobago are large, more ohve in colour, and have the rump slate- 

 grey ; but skins from Trinidad are intermediate. Birds of the 

 year show ochraceous tips to some of the greater wing-coverts. 

 Younij in first pJuimtrie have ochraceous shaft-lines and dark tips to 

 most of the small feathers of the upper parts, and ochraceous centres 

 and dark tips to the feathers of the underparts.

 in North Brazil, Para, East Ecuador, and North-east Peru.
