The ureteral epithelium of male adult rabbits was observed with a scanning electron microscope and the following results regarding the developmental changes were obtained. 1. The ureteral epithelium changes remarkably in form developmentally or on account of mechanical depression or traction. 2. The epithelium which developed in the basement membrane seems to be a ridge toward to the longitudinal direction of the ureter. 3. In the next stage, these cells develop in columnar form and touch with the basement membrane directly or indirectly through another cells. These cells seems to be a pseudostratified epithelium, because they are isolated from other surrounding cells. 4. The epithelial cell with a pointed end matures and it transforms into a flattened one approaching to the inner surface of the ureter. 5. It has become obvious that the covering epithelium of the ureter is a transitional type. Because, numerous furrows are observed on the surface of the covering epithelium reached to the inner surface of the ureter. These furrows indicate the elasticity of the cell.
