This specie* seems to be widely distributed. I have examples from 

 Trinidad, British Guiana, Brazil, the Upper Amazon, and the Rio 

 Xapo, which I refer to it. It may be distinguished from all its near 

 allies, except the next following, by the thickly-feathered white 

 flanks. The specimens from Guiana and Cayenne are blacker on 

 the under surface than the Brazilian bird.

I refer to this species of D'Orbigny, not without doubt, a bird 

 from the Upper Amazon and Rio Xapo, which differs from .1/. axil- 

 laris in the want of the white flanks, and in the termination of the 

 black colouring below at the lower part of the breast.
