fin one third longer than the abdomen, its^ anterior lobe 

 about as high as the soft dorsal. Caudal fin forked, the 

 middle rays shorter than the eye ; caudal peduncle wider 

 than deep. Pectoral fin slightly curved, extending to below 

 the origin of the soft dorsal. Ventral small, reaching 

 midway to the base of the 2nd anal spine. 



Gill-rakers long and slender, 134-35, the longest 1-80 

 in the eye-diameter, but not quite so long as the middle 

 fringes.
