 Head and body strongly compressed, the latter entirely armed with 

 angular osseous plates. Teeth excessively small on both jaws, none on 

 vomer or palatines. Dorsal fins separate; a long, fleshy barbel on tiji 

 of snout; mouth small; a very high, broad, somewhat recurved spine or 

 bony projection above each orbit; occipital spines not prominent; origin 

 of first dorsal above nape, the profile from nape to fin very steep; pectoral 

 rays somewhat exserted ; gill membranes probably united and free from 

 isthmus. Closely related to Hypsagoniis. {Agonus; 6/arAd5, level, even, 

 or flat; i. e., compressed.)
