Ilab. Rio Madeira and Mate Grosso (Natterer) ; Rio Tapajos (Bates) ; Eastern Peru, 

 Chamicurros, and Loreto (JE. Bartlett). 



The occurrence of this Curassovv in British Guiana, though asserted by Schomburgk, 

 appears to be very doubtful. It is a more southern species, and is probably only met with 

 on the south side of the Amazons. Natterer obtained specimens of it near the city of 

 Mato Grosso, and at various other points as he descended the Madeira. Bates met 

 with it on the Rio Tapajos, and Bartlett on the Upper Amazons in Eastern Peru. 



Two males of this species [h and h of list), examined by Mr. Garrod, both presented 

 a fair-sized tracheal loop.

Hah. British Guiana {ScJiomh.) ; Rio Negro {Spix and Natt.) ; Rio Brancho (Natt.). 



Spix, the discoverer of this species, met with it on the Rio Negro, where Natterer 

 also obtained many examples, as likewise on its northern affluent, the Rio Brancho. 

 Schomburgk tells us that it is found on the wooded river-banks of the Savanna-rivers of 

 British Guiana.
