In a recent paper on the Clionidae of Indian seas (Rec, Ind. 
Mus. XI, pp. 1-24) I referred incidentally to other sponges 
parasitic in their burrows. I now propose to give an account of 
these sponges adding some additional notes on the Indian 
Clionidae. 
The systematic position of the different species may be con- 
sidered first, in taxonomic order, and then their biological rela- 
tionships.
