'Typical specimens (received from the Branicki Museum) are undistinguishable 

 from a light-colored example of D. c. uUramarina from Chiriqui. All Peruvian 

 specimens examined agree with the Central American form in the color of the 

 throat (af distinguished from that of D. c. cayana), but none of them exhibit the 

 deep blue color characteristic of most specimens of D. c. uUramarina, being in this 

 respect like true D. my ana.
