Like so many other Upper Amazonian types, e.g. Anoplops salvini, A. melano- 
sticta, etc., this species ranges from Eastern Pern to the left bank of the Rio 
Madeira, but does not appear to occur on the right side of the stream. Miss 
Snethlage* has lately recorded it from the Upper Purts.]

“Tris brown, feet greyish green, bill black, below greyish.” 
The adult birds agree with others from Venezuela (Caura) and Rio Negro 
(Natterer coll.). C. variegatus inhabits the Guianas, the Caura district in Eastern 
Venezuela, as well as Northern Brazil from the upper Rio Negro (Marabitanas) 
to Pard& and south to the Rio Madeira, where it is as yet only known from the 
right bank. In Hastern Ecuador it is apparently replaced by a closely allied 
form, C. salvini Salvad.,f which may be only subspecifically distinct, but so far I 
have not met with this race.

The skin agrees perfectly with several others from Cayenne, etc. The two 
birds named A, rujicollis by Pelzeln are more deeply coloured on the lower parts, 
but similar specimens occur also in Cayenne, Surinam, etc., along with pale-bellied 
ones.
