Light microscopy was used to study the morphology of the radula of four nominal species of the Bithyniidae family living in Siberia: Boreoelona contortrix, B. sibirica, Opisthorchophorus baudonianus, O. troschelii. A significant difference in the structure of radula B. contortrix from the other three species is noted.
