Northern Colombia (Cartagena) to Isthmus of Panama (Lion Hill 

 station, Panama Railroad). 



T have not been able to examine a specimen from the type locality 

 of this species (Cartagena), but the original description applies fairly 

 well to the Panama bird. The birds from eastern Peru, usually 

 referred to this species, however, are very distinct, and should proba- 

 bly' bear the name Bamjihoeelus melanogmtcr Swainson.^
