of second dorsal slightly in advance of origin of anal, the rays varying 
in length, the posterior ones the longest, often reaching base of caudal; 
caudal fin scaly at base, its margin strongly convex; anal fin similar to 
second dorsal; ventral fins rather long, reaching vent and sometimes to 
or past origin of anal, 1.04 to 1.43 in head; pectoral fins long, usually
