Characters. Similar to true C. lucidus of Guatemala, but smaller with 

 shorter and much more slender bill; the adult male with the blue color 

 of the body darker (in true C. lucida body and head are of about the same 

 shade, in the new form the body is darker than the head, the latter being 

 of the same light blue color as in true C. lucida); adult female rather duller 

 green on the back, and with the head less washed with bluish. 



For comparison with these a series of true Cyanerpes lucidus affords 

 the following:
