The anterior ventral ray is elongated, bristle-like. In the peculiar 

 distribution of colours this species much resembles a Datnia from the 

 estuaries of the Ganges described and figured by Buchanan Hamilton 

 as Coius polota,f (pp. 25, 370, PI. 38, fig. 31.) From the latter the 

 present differs not only in the number of its branchiostegous- and fin- 

 rays, but also by its more elongated form. But. two individuals were 

 at different times observed at Pinang : both were taken in rivulets, 

 which however communicate with the sea.

 Anoplus. The latter name however is inadmissible, as it has been preoccupied by
