 eye 3, much greater than snout or interorbital; maxillary reaches 

 three-fifths in eye, expansion 2 in eye, length 2}/g in head from snout 

 tip; teeth villiform, in bands in jaws, on vomer and few on front of 

 each palatine, tongue smooth; interorbital 4 in head from snout tip, 

 slightly convex. Gill rakers 2+9, lanceolate, greatly longer than gill 

 filaments or 3}^ in eye; 2 upper and lower rudiments. 



Scales 18 + 7 + 2 in lateral lines, with last on caudal base; 5 scales

 and anals, and caudal base broadly seal} 7 . Lateral line of simple 

 tubes, upper section high along bases of dorsals on back and lower

 radiating striae; about 40 small apical denticles with 9 series trans- 

 rersely; circuli very fine.
