Tue 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 Gerranus, 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.
