vations separated from each other by narrower lines of the naked lining 

 membrane. The greatest vertical diameter in front of the second dorsal 

 fin equals the length of the head. The lateral line, consisting of little 

 rectangular elevations, follows the outline of the back while gently 

 declining till opposite the third or fourth dorsal spurious fin ; from 

 thence it continues straight to the strong keel in front of the caudal 

 fin. Tn the young of this and the preceding species the latter keel is 

 very little developed. Single individuals occur at Pinang at all seasons, 

 and are valued as articles of food. In Calcutta they are very rarely 

 seen, and during the cold season only.
