Diagtiosis. 



Gymuodontes without either pelvis or ril)s,| with a normally devel- 

 oped caudal regiou,§ with the intermaxillary and dentary bones sever- 

 ally connected by suture at middle, the supramaxillaries curved out- 

 wards behind the intermaxillaries, the ethmoid more or less projecting

Tetraodontoidea with the medifontines articulated with the supraoc- 

 cipitine and the spenotics (postfrontals) confined to the sides, the pros- 



* Odopsia=Gymuodoutes.
