6| in length of head, 1| diam. from end of snout and also apart. 

 Head rather compressed, snout pointed. Posterior border of pre- 

 opercle short, angle rounded, and lower edge at least twice as long 

 as vertical. Fins first dorsal spine the broadest, equal in height 

 to second, and k as long as head. In some specimens the first 

 dorsal fin is continued to within a short distance of the second, in 

 others (as in the one figured) the last few spines are nearly or 

 quite hidden in the integument. Second dorsal highest anteriorly, 

 having a concave upper edge, its three spines are short and con- 

 cealed by the skin ; finlets rather large. Between the two ventral

fins an oval or elongate lamella, under which they can be partially 

 received. Anal similar to second dorsal, the three spines equally 

 concealed. Scales forming a corselet anteriorly in three portions 

 separated by two deep emarginations. Superiorly the corselet 

 embraces the two dorsal fins, and is divided from its central 

 portion by an emargination which reaches to below the eighth 

 dorsal spine. The central portion of the corselet is mostly beneath 

 the pectoral fin, and the emargination which divides it from the 

 inferior portion extends to below the base of the pectoral. The 

 lowest portion goes to below and behind the ventral fins. Colour 

 bluish along the back, with a number of undulating oblique 

 dark bands ; silvery below the lateral line ; sometimes black spots 

 on the chest or breast. 



Hub. Bed Sea, seas of India to the Malay Archipelago, where 

 this fish is common during the cold months ; also found in the 

 Mediterranean, tropical parts of the Atlantic, and in Scandinavian 

 seas. Often seen in the Bombay markets in the cold season up to 

 two feet in length.
