This genus is closely allied to Carnnx, from which it differs only in its 

 distortion of form, and in its weak teeth and very low tins. Body broad 

 ovate, very strongly compressed, all the outlines sharply trenchant. 

 Head very gibbous above the eyes, its anterior profile vertical ; lateral 

 line strongly arched, its posterior portion with very weak shields. Scales 

 minute, rudimentary ; soft dorsal and anal extremely low, not falcate. 

 Young much deeper in form than the adult, all the fins higher, resembling 

 Selene. Warm seas, {vomer, a plowshare, from, the form of the body.)
