 outer secondaries and tail ferruginous; beneath paler; throat j)ale

 tail rufescent [" rubiginosis "], wing-coverts concolor with back, head 



« Ten specimens from southwestern Costa Rica . 



b Seven specimens. 



c Among specimens from Boruca are some that I can not distinguish from typical 

 D. sancti-thomse; in fact, while the difference of coloration in the two forms is quite 

 obvious when extreme examples are compared, the absence of strict corellation 

 between the color-differences and geographic distribution is difficult to understand.
