A pair of birds from Buena Vista near the eastern base of the Eastern 

 Andes appear to be typical of this form, the female being grayer than any 

 of om- females from Matto Grosso. We have, however, no topotypical 

 specimens from the lower Amazon.

An adult male from Noanama agrees in size with specimens of T. s. 

 esmeraldoe from Esmeraldas, Ecuador, but resembles Santa Marta speci- 

 mens in color and in the pattern of the tail-markings, the black area on the 

 inner vane of the outer feather being separated from the shaft by a white 

 line connecting the white basal and apical portions of the feather. On the 

 other hand specimens from Dabeiba and Puerto Valdivia agree in size with 

 C. columbiana (wing, 124 mm.) but the tail-markings are not so near those 

 of columbiana as in the Novita specimen, the black on the inner vane of 

 the outer feather reaching to the shaft, though by no means so broad there 

 as on the inner border of the vane. 



Our series of eight topotypical (Santa Marta) specimens of this form 

 differ from Chapada, Matto Grosso, specimens in having the black frontal 

 band slightly narrowjer and in being smaller, while the females average 

 darker.

 (Esmeraldas, Ecuador). 



Char, subsp. — Tail in the male with a broad subterminal black band which 

 reaches the shaft of every feather and is of essentially equal extent on each; closely 

 agreeing therefore in tail-pattern with T. s. costaricensis but with the terminal white 

 band narrower, the subterminal band broader, the body plumage whiter and size 

 smaller; female wholly unUke the female of costaricensis, and closely resembhng in 

 general coloration the female of T. s. semifasciata but with the black subterminal 

 band much broader, the basal gray band correspondingly reduced, and dimensions 

 much smaller. 



A female from Barbacoas agrees in color and size with specimens from 

 Esmeraldas, Ecuador.
