摘　　要：扁玉螺消化系统由消化道——口、食道、胃、肠和直肠以及消化腺——食道腺和肝脏组成，无唾液腺．消化道粘膜上皮有纤毛柱状细胞、杯状细胞和颗粒细胞三种细胞．食道腺仅有一种腺细胞．肝脏由消化细胞、隐窝细胞和贮藏细胞组成。The digestive system of Neverita didyma Rding consists of digestive tract mouth, esophagus,stomach,intestine and tectum,and digestive glands esophageal gland and liver, no salivary gland. The epithelium of the mucous membrane of the digestive tract is composed of columnar ciliated cells, goblet cells and granular gland cells.A kind of gland cells is only distinguished in the epithelium of the esophageal gland. The epithelium of the liver consists of digestive cells,crypt cells and storage cells. The storage cells have not been found in the liver of other Gastropods.
