 ULTRAMARINE DACNIS. 



Similar to I), c. caj/ana, ])iit adult male usuall}' 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 ti-ue D cayana, being much larger as well 

 as greener than the typical form from the Iow^t .\uiazon Valley, Cayenne, etc.
