Abstract
The radulae of six species of bithyniid snails, Bithynia striatula, B. tentaculate, B. siamensis, B. leachi, Gabbia misella and G. australis, were observed by SEM. The radular formula of all the bithyniids studied was 2 : 1 : 1 : 1 : 2. The all teeth were multicuspid and the central teeth had numerous basal denticles. The mesocones of the central and lateral teeth were spade or arrow-head shape. The mesocones of the central teeth and the lateral teeth of B. leachi, G. misella and G. australis were slightly larger than the other cusps in contrast of those of the other species. Number of cusp was varied by the specimen and the species.
