The excretory organs of oedematous tadpoles of Bufo vulgaris formosus (Boulenger) were histologically observed. In the limb bud stage, a discordance is found in these tadpoles between the degeneration of pronephroi or pronephric ducts and the development of mesonephori. This occurs in the following three manners. 1) The degeneration of pronephroi or pronephric ducts occurs earlier than in the normal tadpoles, when the mesonephroi cannot yet be functional. 2) While the degeneration of pronephroi and pronephric ducts take place normally, the mesonephroi are delayed in development. 3) The degeneration of pronephroi and pronephric ducts is more conspicuous than in the normal tadpoles, and, moreover, the mesonephroi are underdeveloped and especially the mesonephric ducts are rudimentary.
