 reaching vent, one-half-head. Pectorals long and narrow, reaching 

 front of anal, with narrow scaly base, the posterior margin obliquely 

 truncate or somewhat /-shaped in the spread fin, the lower rays

 peduncle. 



Head, 2J in length; depth, 3i; depth of caudal peduncle equaling 

 diameter of orbit. D. IX, I, 12; A. Ill, 7. Lat. 1. 48, 4i series above 

 it, thirteen between lat. 1. and front of anal. Five series of scales on 

 cheeks parallel with posterior margin of orbit. 



Color in sjnrits : Dusky brownish above, lighter below; a series of 

 about seven ill-defined dusky blotches along lateral line, from which 

 si ill fainter bars run downwards, soon disappearing. Lining of opercle

Specific description: Body elongate, tapering regularly backwards 

 from shoulder, the lower outline nearly straight; head thick; mouth 

 terminal, oblique, the mandible laterally included, its tip fitting into an
