NO. 2 BIRDS OF ISLA ESCUDO DE VERAGUAS — WETMORE IO, 



del Toro, Panama. Specimens from Cricamola at the eastern end of 

 the Laguna de Chiriqui are intermediate toward castaneus. 



Sharpe described this bird from a single specimen that he said was 

 collected by Adolphe Boucard in Costa Rica, without giving a more 

 definite locality. Boucard (1878, p. 51) in an account of his collec- 

 tions made in Costa Rica listed this wren as Thryophilus castaneus 

 Lawrence, with the statement "Several specimens, from San Carlos ; 

 killed in February." In his itinerary he says that this locality was in 

 the Valley of the Rio San Carlos, a tributary of the Rio San Juan on 

 the Atlantic slope. I have therefore designated this area as the type 

 locality.
