Testaceous amoebae in plankton peryphithon and benthos of the Ganlı-Gol lake in the Baku suburbs were investigated with respect to specific composition and number. Twenty-four of 64 species were recognized as a new faunal assemblage for the Caucasus. The largest diversity and number of species df testaceous amoebae occurred in benthos in silty deposits. Representatives of Difflugiidae, Centropyxidae and Arcellidae families appear to be dominant on the basis of the abundance of species.
