Eye located midway between tip of snout and opercle, its upper 

 edge almost on a line with dorsal contour of head. Interorbital space 

 somewhat convex, the width equal to or greater than diameter of eye, 

 the proportions differing with age. Lower jaw included; maxillary

 of eye, its upper edge, except at tip, covered })y preorbital. Teeth 

 villiform, in bands on jaws, vomer, and palatines; premaxillary band 

 broadening posteriorly, then narrowing and growing sharply pointed 

 at the ends; mandibular band gradually narrowing from before back-

 others when tin is depressed, 1^ in head, apparently not preceded by 

 a minute, embedded spine; membrane of tin extending to tips of spines.
