The nostrils are oval and partially covered by the frontal bristles, which are well developed. The feathers of the crown are somewhat ample, but they do not form a crest.

The wing is rounded; the tail is about two thirds the Length of. the wing and slightly rounded, and its coverts reach to about the middle of the tail. The tarsus is strong and smooth.

The birds of this genus are entirely arboreal, being found in flocks traversing the highest trees. They are confined to the hilly portions of the country, and feed upon both insects and berries.
