extremely delicate membrane, in which rays are visible like fine striae, and which on its 

 hinder margin is provided with long fringes. The eight lower or anterior rays are quite

 snout, and considerably less than the width of the interorbital space, which is very convex. 

 Jaws even in front, the maxillary extending nearly to the hind margin of the orbit.
