 ^ I have not seen specimens from Ecuador. The three forms which occur in Col- 

 ombia may be readily distinguished by the color of the throat. 



1. A. a. albivitta, throat grayish white or whitish. 



2. A. a. griseigularis, throat gray. 



3. A. a. phaolcemus, throat bluish gray or grayish blue.
