Widely distributed from the Tropical Zone of the Pacific coast to the 

 Eastern Andes and ranging upward to the lower border of the Subtropical 

 Zone. Specimens from the Pacific coast differ from those from the Mag- 

 dalena Valley (which may be considered essentially topotypic3,I) , in having 

 less bronze in the tail and the imderparts bluer green. They thus approach 

 C. casruleogaster of the eastern slopes of the Eastern Andes.

 this species appears to represent C. b. buffoni found by us only west of the 

 eastern slope of this range.
