 of the common Mackrel : scales small : lateral line 

 pretty distinctly marked at its beginning, curving 

 over the base of the pectoral fins, and afterwards 

 becoming very strongly mailed by broad acumi- 

 nated scales, and running strait to the tail, which 

 is strongly forked : fmlets ten both above and 

 below : before the anal fin two strong spines, con- 

 nected by a membrane. Native of the Indian

 rather coarse.
