A study was recently made on a small collection of Radula made by Dr. K. Stella Gambarjan in the Primorye territory of USSR. In 12 collections four species were recognized : Radula auriculata, R. complanata, R. constricta, and R. obtusiloba. R. auriculata is the first record from USSR, and R. obtusiloba is a new addition to the hepatic flora of continental USSR.
