Head lar<ie, dieej), or with <i;reate.st depth of entire body fulling at 

 orijiiin of ventral, and u])per profile at first very steeply inclined up from 

 tip of snout till above front of eye, and then slightly inclined to origin 

 of dorsal. Snout rather broadly convex over surface, so that its 

 Avidth is a little gi'eater than its length. Eye large, circular, close to 

 upper profile, and placed about first third in head. Mouth large, low,

Skin naked and apparently smooth. Lateral line of simple tubes,

 down till about lower g in depth of trunk at that point. About 20 

 tubes, each opening in a pore, in anterior curved jiortion of lateral 

 line, and about 9 tubes continued back in a straight series anteriorly.
