Pelzeln's Cactus-Wren is stated to be from Spanish Guiana. It 

 was only known from the description given by Herr von Pelzeln 

 (I.e.), who remarks that it is similar to //. r/riseus, but is larger, the 

 upper surface and the wings externally being uniform dull brown. 

 A specimen of Schomburgk's seems, however, to belong to this species, 

 which must therefore also inhabit British Guiana.
