" Iris dark brown, feet and bill black." 



The females are smaller, with the median i-ectrices less elongated, 

 and the pileum is uniform dark sooty without hoary margins. 



There is apparently no diflerenoe between specimens from so 

 widely separated localities as Costa Rica and Colombia,, nor do 

 skins from Western Ecuador differ.

'•'■ Iris dark brown, feet pink, bill black." 



This bird is quite typical. Skins from Chiriqui and Costa 

 Rica agree in coloi'ation, but are slightly smaller (wing 57- 

 59 mm.). I have not seen specimens from Eastern Ecuador t and 

 Northern Peru % which may, or ma.y not, be strictly referable
