Body oblong, abruptly tapering at both ends, stout, short, its 

 greatest hight one fourth of total length to end of middle caudal 

 rays, its ^Yidth a little more than one half the length of head, 

 equal to postorbital part of head; least hight of caudal peduncle 

 one half the length of eye; keel one fourth as long as the head; 

 head rather long, somewhat compressed, acute in front, conical, 

 its length two sevenths of the total without caudal, its width 

 over the opercles one half its length; snout not long, acute at tip, 

 somewhat compressed, its length two sevenths of length of head; 

 the mandible heavy and prominent, scarcely projecting; the 

 maxilla with rounded extremity extends to below middle of 

 pupil; the mandible extends to below hind margin of eye, its 

 length nearly one half the length of head. The eye is obliquely 

 oblong, its length about one fifth of length of head. The spinous 

 dorsal orginates immediately over the origins of the pectoral 

 and ventral; the base of the fin is four fifths as long as the head; 

 the first and longest spine one half as long as the head, the last 

 spine one fourth as long as the snout. The interspace between 

 the dorsals equals two thirds of length of snout. The second 

 dorsal is equidistant from the upper angle of the gill opening and 

 the base of the caudal fin; the base of the fin is as long as the 

 snout and equal to base of anal; the longest ray is a very little 

 longer than the base of the fin, the last ray is one fourth as long 

 as the snout; the fin is followed by eight finlets, the largest in 

 front, two fifths as long as the snout. The middle caudal rays, 

 measured from keel, one third as long as the outer rays, which 

 are nearly two thirds as long as the head (equal to postorbital 

 part of head). The anal origin is nearly under the end of the 

 second dorsal; the base of the fin is two sevenths as long as the
