B. aculeatus (3 viridis. First dorsal fin three-rayed. Tail entire, with

The Ratoopotobarah, or Mol-Kotah of the Cingalese, inhabits 

 rocky situations. It is eaten by the natives; but, owing to its 

 insignificance as an article of food, and its almost impenetrable skin, 

 is never sought after by the regular fisherman. 



This fish seldom exceeds nine or ten inches in length ; and when it 

 attains that size, the green colour of the body gives place to a darker 

 hue, and the fine orange colour of its lines and fins becomes of a dusky 

 yellow. 



Figure — Half the natural size of the Specimen.
