 Carnegie Museum: Guapiles (Carriker). Two skins. 



This is a well-marked bird, and need not be confused with the other 

 forms of Stelgidopteryx in Costa Rica, being easily distinguished by the 

 rufous throat and black tips to the under tail-coverts. 



It has been taken on both the Caribbean and Pacific slopes from 800 to 

 2,000 feet, and probably is found over the whole of the lowlands and foot- 

 hills. I found the birds breeding at Guapiles.
