 abstract={44 samples taken in two different months (July 1952 - 31 samples, September 1952 - 13 samples) from various species of plants growing in the water of one of the old branches of the Vistula, now cut off from the river, confirmed the occurrence of the following species of Rotatoria:Collotheca gracilipes (Edmondson 1939)Collotheca ornata cornuta (Dobie 1849)Floscularia ringens (Linneus 1758)Lacinularia flosculosa (Müller 1773)Limnias ceratophylli (Schrank 1803)Ptygura sp.Sinantherina socialis (Linneus 1758)Stephanocereos fimbriatus (Goldfus 1820)One of the above species, Collotheca gracilipes, found by Edmondson in similar environments in the United States, is new to Polish fauna. The wide differences in the numbers of individuals obtained from consecutive samples indicates both the sporadic character of the occurrence of Rotatoria in this plant environment, and the tendency to form groups.Several groups were distinguished of the following species: Collotheca ornate cornuta and Limnias ceratophylli, which are the most common and most numerous specimens of Rotatoria in the environment examined. They form about 93% of the entire material collected. The remaining species occur rarely and in very small numbers.The following plants are the ones chiefly settled by the Rotatoria: Ceratophyllum demersum, Elodea canadensis, Myriophyllum spicatum, Najas minor and Ranunculus spicatus. About 97% of the entire Rotatoria fauna occurs on these plants.},
