Morphology and distribution of Argyrophil cells in the digestive tract in the postembryonic development of Salamandrella keyserlingii were investigated by means of silver nitrate method of Grimelius. The result showed: Argyrophil cells first appeared between mucous epithelial cells in the stomach of Salamandrella keyserlingii at stage 41 in round, oval, as well as conical shapes, with their processes extending to nearby cells. Argyrophil cells were first observed in the intestine at stage 42. They mainly distributed between epithelial cells in cone-shape or shuttle-shape. Argyrophil cells appeared in the esophagus as late as stage 43. They mainly distributed between epithelial cells in various forms. According to the morphology of the argyrophil cells, they have endocrine and exocrine functions.
