Genus Thamnophilus, Vieillot. 235 



13. Thamnophilus hyperythrus, Gould. 



9 T. supra schistaceus ; alis caudaque nigris, tectricibus ala- 

 ribus albo guttatis ; subtus rubro-ferrugineus ; rostro nigro. 



Long, tota 7 # 0, alae 3-2, caudae 2*3. 



Hab. Chamicurros, on the Peruvian Amazon. Mr Gould's 

 bird is marked " female, irides brown." It is the only indi- 

 vidual I have seen of the sort. Chamicurros I take to be the 

 place marked Camucheros in the Society's Atlas, on the right 

 bank of the Amazon above Tabatinga.

Hab. British Guiana (Schomb.) ; Cayenne (Buff.) ; Trini- 

 dad (S.), Nicaragua and Guatemala (Bp.) 



Specimens of this bird from Cayenne, Guiana, and Trini- 

 dad agree well, and must be taken for the true " doliatus " 

 of Linnseus. Nor can I discover any great points of difference 

 between these and the examples I have seen from Central 

 America, and must therefore conclude that the range of this 

 species extends beyond the Isthmus of Panama, though seve- 

 ral corresponding forms represent it in the intervening coun- 

 tries, where this bird does not appear to exist. Schomburgk 

 says it is one of the commonest birds of the coast of British 

 Guiana. Its favourite resort is the thick Avicennia bush and 

 damp underwood. It is an active bird, always in motion, and 

 slips quickly through the thick bush. The male and female
