## Summary

Dr. N. Annandale's volume on the Freshwater SPONGES, POLYZOA, and HYDRIDA contains an account of three of the chief groups of freshwater organisms. Although he deals mainly with Indian forms the book contains an unusually full account of the life-history and bionomics of freshwater Sponges, Polyzoa, and Hydrozoa.
