Common in the Subtropical Zone of all three ranges. Specimens from 

 the Central and Western Andes average somewhat darker below than those 

 from the Bogota region; some of them closely approaching Santa Marta 

 specimens of P. b. coloratiis Bangs.

A specimen from Villavicencio cannot be satisfactorily referred to any 

 of the recognized forms of this species. It has the throat ochraceous-buff, 

 with barely perceptible margins, and is thus unlike true cuneattis in which 

 the throat is but faintly tinged with buff and distinctly margined. The 

 underparts have a more olivaceous cast than in the other forms, identi- 

 fication of this specimen would not alone require additional examples from 

 Villavicencio, but a revision of the entire group, which appears, from a 

 casual examination of the specimens in our collection, to contain several 

 undescribed forms.

Seven specimens from the Tropical Zone in Amazonian Colombia, agree 

 essentially with one from Pebas, Peru, and are apparently, therefore, typical. 

 Together with four specimens from the foot of Mt. Duida they possess the 

 cinnamon-rufous throat which characterizes this form.
