transverse series counted from vent upward and backward to soft 

 dorsal ; twenty-two predorsal scales. 



Body oblong, elongate, tail very slightly compressed; dorsal profile 

 nearly straight, more or less descending anteriorly, ventral profile 

 strongly curved ; head rather small, with depressed top ; interorbital 

 space broad, nearly flat ; snout short, truncated in front ; mouth sub- 

 inferior, oblique, its angle reaching beyond a vertical through the 

 posterior nostril; cleft of mouth one and half times as broad as deep; 

 mandibular angle obtuse; extremity of maxillary not exposed; lower 

 part of anterior and inferior edges of preorbital denticulated; lower 

 jaw slightly shorter than the upper, outer edge rather sharp, with an 

 inner median keel, which fits into the corresponding concavity on the 

 roof of upper jaw; microscopical teeth on both jaws; upper lip fleshy; 

 lower lip thin, distinct at the angle of mouth only ; mandible with two 

 pairs of small open glands beneath ; eye large, with well-developed 

 adipose eyelid, which covers part of iris anteriorly and posteriorly; 

 nostrils well separated, the anterior a single pore, the posterior slit- 

 like, in front of eye above. 



Scales large, cycloid, outer margin rounded, those on the top of 

 head somewhat larger than others, not reaching to tip of snout; a 

 sharply pointed scaly flap along the base of spinous dorsal ; pectoral 

 scaly flap rather short and broad ; ventral with a sharply pointed scaly 

 flap at the root ; a triangular, broad scaly flap between ventral bases ; 

 all the fins, except spinous dorsal, covered with minute scales. 



Origin of the spinous dorsal a little nearer to tip of snout than 

 base of caudal, first and second spine subequal in length ; soft dorsal 

 inserted slightly nearer to origin of spinous dorsal than base of 

 caudal ; origin of anal one scale in advance of that of the soft dorsal, 

 much nearer to caudal base than origin of ventral ; pectoral inserted 

 above the middle of body, rather short, not reaching to the spinous 

 dorsal ; ventral inserted below the apical one-third of pectoral, not 

 reaching half-way to vent; caudal fin forked. 



Color dark gray above, belly and lower part of sides silvery; shin- 

 ing dark stripes along several series of scales ; pectorals, dorsals, and 

 caudal dusky, the rest of the fins whitish; a black speck at the base 

 of pectoral. 



Total length 600 mm.
