Description. —A bright silvery fish with a very bowed back and an almost 
straight abdomen. Body much compressed. Scales very small Lateral line dis¬ 
tinct. Abdomen with a double serrature. Upper profile of the head concave. Nar¬ 
row bands of small teeth on both jaws ; two series of teeth on the tongue. Anal 
fin very long, and united with the caudal; dorsal fin very short. Ventral fins 
wanting. Dorsal rays 8 to 10 ; anal, 110 to 125 ; scales, 180. This fish is sometimes 
marked with dark crossbands on the back, and with round black occellated spots' 
along the lower part of the tail. Its mouth is remarkably small, and it is best 
taken by slow spinning and constant waits on the bottom, and using a sensitive 
rod, for it is a very gentle nibbler. It runs from a few inches in length up to 
nearly 4 feet, and has a peculiar habit of rolling over and over on the surface of 
the water, and jumping clean out of it towards evening.
