Scales. Body covered with cycloid scales of moderate size, which are con- 

 spicuously concentrically striated, and have radiating ridges on their basal por- 

 tions : they are slightly larger posteriorly than anteriorly, and are largest on the 

 silver lateral band ; those of the median row on the back before the dorsal fin are 

 larger than the others on each side of them : the scales cover the base of the 

 catidal fin, extend forward to between the eyes, and become much enlarged on the 

 top of the head : there are 13-14 row s between the liack and belly before the second 

 dorsal and anal fins, and 31-33 on the lateral band from behind the pectoral fin to 

 the hypural.
