 peduncle in head 2; eye 3.5; snout 3; maxillary 4; interorbital 3.33; pectoral 1.5;

 back; longest rays equal to length of head; caudal deeply forked; pectoral short; 

 narrowly rounded; apex falling short of ventral base by a distance equal to 

 diameter of eye; ventrals inserted under second dorsal ray, short, not reaching

 head, and reaches about half-way to the base of the caudal when depressed. 



Color on top of head and back dark; scales on sides above level of pec- 

 torals each with a large, vertical, crescentic area of dusky, producing a spotted
