DACNIS CAYANA ULTRAMARINA (Lawrence). 

 ULTRAMASINE DACNIS, 



Similar to D. c. cayana, but adult male usually with the blue of a 

 much deeper and less greenish hue, the color changing from bright 

 ultramarine or cobalt blue when viewed toward the light to greenish 

 blue viewed from the light; chin and throat decidedly duller black,^or 



' The throat is similarly dull colored in examples of so-called D. cayana from 

 southwestern Brazil (Chapada) , but the birds from that district should undoubtedly 

 be separated as a distinct subspecies from true D. cayana, being much larger as well 

 as greener than the typical form from the lower Amazon Valley, Cayenne, etc.
