采用扫描电镜技术对江西省分布的7科11属15种陆生贝类的齿舌进行了观察与详细描述.结果显示所研究的15种陆生贝类中,除环口螺科的矮小双边凹螺Chamalycacus nanus侧齿和缘齿均仅有单列外,其他各科种类均由多横列组成.每一横列上又包含若干个齿片.不同科的种类齿片上缘或侧缘的数目和形态有较大差异.同一属间种类的齿片形态较为相似.

The radula of 15 species of terrestrial mollusks, belonging to 7 families 15 genera, are compared on the basis of scanning electron microscopic(SEM)observation and described detaily. The results indicate that all of them consist of several rows of lateral teeth and marginal teeth except Chamalycacus nanus, which is belonging to Family Cyclophoridae. The radula bears many transverse rows of teeth, and a number of teeth in a transverse row. But the teeth all bear cusps. There are many obvious differences in number and shape of lateral teeth and marginal teeth of different families. The cusps in the same generas were similar with each other.
