Under this head I propose to place Arremon and its allies, in which 

 the bill is shorter and nearly conical, and the feet are much weaker 

 than in the last section.

The shorter and more conical bill distinguishes this genus from 

 Buarremon ; the tail is also shorter and but slightly rounded. The 

 coloration is mostly olive above and white below, with a more or 

 less evident black gorget ; the head is black, often with a white or 

 greyish superciliary and mesial stripes. The fourteen species of 

 Arremon range from Southern Mexico to Northern La Plata.
