The Tik Kossah of the Cingalese inhabits rocky situations, seldom 

 exceeds eighteen inches in length, and is a firm-fleshed and whole- 

 some fish. 



Many of the fishes on the coast of Ceylon vary in their colors 

 after having attained their utmost length ; therefore the most brilliant 

 specimens are those of medium size. Gratitude for kindnesses re- 

 ceived, and favorable recommendations to the author's superiors in 

 India, (however neglected by those to whom addressed,) have induced 

 the denomination of this Gcrranus, the only mode the author has of 

 recording his deep sense of respect to the memory of the late Right 

 Hon. Charles Augustus, Earl of Tankerville.
