I am by no means satisfied that all the above-mentioned specimens represent a 
single form. Six males (three fully adult, three evidently immature) from the 
Santa Marta district of Colombia have the middle rectrices wholly metallic bronze 
or greenish bronze and the remaining rectrices (except the outermost) broadly edged 
with the same, at least basally. On the other hand, fully adult as well as immature 
males from the lower Magdalena and Bogot4 districts and those from Venezuela have 
the middle rectrices either very dull bronzy or blackish faintly glossed basally with 
bronzy, while two from Panamé (the only ones seen from that district) have the 
middle pair of rectrices wholly blue-black like the rest of the tail, and the upper 
tail-coverts purplish bronze. The series examined is, however, much too small to 
enable one to decide the question properly.
