Habitat. — Guatemala to Colombia.

 shining greenish-bronze, next one shining bronze-green with 

 dark brownish spot on inner web near the inner tip which is 

 white, last lateral and outermost ones shining bronzy-green 

 with a subterminal blackish bar and broadly tipped with white. 

 Underside dull bronze-green passing to gray, with rufous tinge 

 on abdomen and flanks. Undertail-coverts bronzy-green 

 fringed with white. Wings purplish-brown. Maxilla black. 

 Mandible flesh colour for a little more than half its length, 

 rest black. 



Total length, 4^in. Wing, 2|^. Tail, i|^. Culmen, |-. 



Female. — ^Exactly like the male. 



The differences between C. roberti, and this species are so 

 slight, that I cannot see how they can be separated. 



In one specimen which I have from Guatemala, the base of 

 the mandible is flesh colour, and the lateral rectrices have a 

 broader blackish subterminal bar, but the base is also bronzy- 

 green. 



It is a rare species. 



I have collected my specimens in Guatemala, Costa Rica, 

 and Colon. I have also one specimen collected by Arce, at 

 Chiriqui. 



The type of this species was discovered by Delattre, in 

 Guatemala, and it was dedicated by him and Bourcier, to the 

 eminent French Naturalist, Cuvier.
