Body oblong, compressed. Mouth large, terminal, oblique j jaws 

 about equal, their edges nearly straight 5 maxillary extending to the 

 front of the eye. Premaxillaries narrow posteriorly, anteriorly protrac- 

 tile. Villiform teeth in bands on jaws, vomer, and jialatines. Species 

 numerous, mostly European. {aOzjih-q.^ the ancient name, from d^ij^o, a 

 barb or spike, from the form of body or the numerous bones; possibly 

 from aOepi'Ut'', to despise, from their diminutive size.)

 greater than interorbital width and more than twice the length of the 

 snout. Spinous dorsal beginning behind the vertical from the tips of
