Body elongate, slender; head narrow, depressed. Snout long, 

 tapering, blunted at end; eye small, pupil horizontal, orbit 2% in 

 snout; mouth small, width % snout length, length half its own 

 width, short labial folds less half jaw length, upper little longer; 

 teeth smooth, cusps rather produced and angular, with concave in- 

 dentation on outer edge, though not denticulate ; nostrils at last third 

 of preoral length, front valve produced in rounded lobe. Gill open- 

 ings narrow, greatest width % orbit length. 



Fins all concave on hind edge and rounded on outer angles first 

 dorsal origin above inner pectoral angle, height % base length which 

 half space to second dorsal, end reaching opposite ventrals; second 

 dorsal base nearly equals first, fin about half as large, middle of 

 base above anal origin; anal extends l^ orbit length farther back 

 than second dorsal, base length % of space to subcaudal; caudal 

 nearly 5 in total, subcaudal weak ; pectoral rather small, not reaching 

 middle of dorsal base, width li/^ in length.
