Amazonia. A pair obtained at Xeberos by Mr. E. Bartlett consist 

 of an old male and a younger female. They can scarcely be called 

 the same as T. rufulus, for the male differs from the Ecuador birds 

 in its distinctly barred under tail-coverts, though it agrees with 

 them in its whitish throat. I consider, however, that they are 

 nearer to the Guiana and Ecuador form than any of the others. 



The White-breasted House- Wren ranges from Guiana through 

 Teuczuela and Trinidad to the Sierra Nevada of Santa Marta. It 

 also inhabits Ecuador, and extends to Upper Amazonia; here it is 

 less typical.
