GLOSSOPHAGA, with various other genera ending with CH@RONYc- 
TERIS, compose the group GLOSsSOPHAG#®, the members of which are 
distinguished by the long, slender tongue covered with papille, and 
by the deep groove in the under lip. They feed on fruit, berries, and 
insects, and they vary so much from each other in the shape and 
number of teeth and other characters, that there are almost as many 
genera as species. Some are widely distributed and very abundant, 
while others are local and comparatively rare.
