658 Bett— On the Echinoderm Fauna of the Island of Ceylon. 
DESCRIPTION OF PLATES XXXIX. anp XL. 
[The figures here given are illustrations merely of the external form of certain Holothurians; but, 
as these creatures are greatly deformed by preservation in spirit, and speedily become deprived of all, 
or much of their colour, the drawings taken on the spot, and from living specimens, are of especial 
interest and value ; they are here reproduced exactly as they left the hands of the Cingalese Artist.]
