Body fusiform, much tapered at both ends, moderately com- 

 pressed, its greatest hight one fourth of total length without 

 -caudal, its width one half the length of the head; least depth of 

 -caudal peduncle one third of length of snout; keel well devel- 

 oped, three eighths as long as the head; head moderate, pointed 

 in front, its length one fourth of the total to end of middle 

 caudal rays, its width over the opercles equal to eye and snout 

 combined ; snout not long, acute at tip, its length two sevenths 

 of length of head; the interorbital space equal to snout; the 

 mandible heavy, not projecting, the maxilla expanded poster- 

 iorly, extending to below middle of pupil; the mandible extends 

 to below hind margin of orbit, its length nearly one half the 

 length of head. The eye is one fifth as long as the head, and 

 two thirds of width of interorbital space. The spinous dorsal 

 originates directly above the insertion of the ventral and 

 slightly behind that of the pectoral; the base of the fin is nearly 

 as long as the head; the longest spine is one half as long as 

 the head, the last spine 'about one half as long as the eye; 

 the interspace between the dorsals extremely short. The sec- 

 ond dorsal is preceded by a short, stiff spine, which is about one 

 third as long as the eye; the base of second dorsal is one fourth 

 as long* as the head; the longest ray is two ninths as long as 

 the head, the last ray one half as long as the eye; the fin is 

 followed by eight finlets, of which the fourth is longest, two 

 thirds as long as the eye. The middle caudal rays, measured 

 from the root of the fin, are two fifths as long as the tmter rays, 

 which are two thirds as long as the head. The anal origin is 

 under the first detached finlet; the base of the fin is as long 

 as the snout; the longest ray two ninths as long as the head, 

 the last ray two thirds as long as the eye; the fin is followed 

 fcy seven finlets, which are similar to the dorsal finlets. The
