The height of the body is rather more than one-half of the total 

 length (the caudal fin not included) ; the width of the interorbital 

 space is more than that of the orbit ; the scales advance to the front 

 margin of the eye. The breadth of the infraorbital ring below the 

 centre of the eye is more than one-half of the greatest breadth of the 

 prsBorbital. Teeth very narrow and slender ; vertical fins obtusely 

 rounded ; caudal deeply emarginate. Body with about six dark, 

 rather indistinct cross-bands, broader than the interspaces of the 

 ground-colour between them ; a large black spot across the back of 

 the tail, immediately behind the dorsal. 



Young specimens have the anterior half of the spinous dorsal fin 

 black.
