GLOSSOPHAGA, with various other genera ending with CHOSRONYC- 

 TERIS, compose the group GLOSSOPHAGA, the members of which are 

 distinguished by the long, slender tongue covered with papillae, 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.
