Inhabits the Tropical Zone of the Cauca and Magdalena Valleys. Speci- 

 mens from the vicinity of Honda are doubtless topotypical, and with Cauca 

 Valley birds average larger and have more jpurple above than those from the 

 northern parts of the range of the species (Costa Rica to east Venezuela) for 

 which von Berlepsch^ accepts the name brachyptera (Cab.). 



Specimens from Puerto Berrio, while as small as northern birds, have 

 the purple color above of extreme examples of crassirostris.
