Hydrozoa and Ctenophora. 
117 
A ctenophore that answers well with Browne's description was common in the 
outer part of the Tale Sap in January, 1916, in water of a specific gravity (corrected) 
of from 1-0062 to 1-0085. 
This form is intermediate between the forma typica of the species ' from the 
Malay Archipelago and the race ' that occurs in the upper part of the Bay of Bengal ; 
it has been known hitherto only from the coast of Ceylon.
