The height of the body is one-third of the total length (without 

 caudal), the length of the head one-fifth. Snout scarcely as long as 

 the eye, with the lower jaw projecting beyond the upper. Cheek 

 entirely covered by the suborbital ring. The first dorsal ray is oppo- 

 site to about the eighth of the anal fin. Pectoral fin much longer 

 than the head, but not quite reaching the anal fin. Outer ventral 

 ray prolonged into a long filament, the other rays being quite rudi- 

 mentary. Greenish, with a silvery lateral band.
