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 Bogota districts and those from Venezuela have 

 the middle rectrices either very dull bronzy or blackish faintly glossed basally with 

 bronzy, while two from Panama (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 jjurplish bronze. The series examined is, however, much too small to 

 enable one to decide the question properly.
