Fresh-Water Sponges From China and Description of 3 New Species

The paper gave a view of classification and geographical distribution for the fresh-water sponges (Spongillidae) from China.Though 26 species and varieties in 5 genera have been recorded,they are only a very small portion of the fresh-water sponges in China.It is clear that an instensive study of the fresh-water sponges in our country should be made.Their geographical distributions are from 100°23′ to 124°0′ east longitude and from 23°1′ to 35°0′ north latitude.This paper dealt with the descriptions of 3 new species in the genera Spongilla and Trochospongilla from China.They are S.jiujiangensis sp.nov.,S.chaohuensis sp.nov.and T.tsingpuensis sp.nov.
