It's very oeclogically interesting that the kidney of the chiroptera is different from that of the mammalia, rather similar to that of the aves at several respects ; moreover in my studies there were some special findings about it. so I adjusted in the essay. Materials were Rhinolophus ferrum-equinum , Rhinolop. cornutis, Pipisterus abramus, Miniophtereus schreibersii japonicae and Plecotus auritus Lineaus. I compared them with the ayes, rodentia and carnivora concering the structure of the kidney. The papilla of chiropteran kidney extends longly to ureter; it resembles to the medulary cylinder of the aves. On the sagittal plane through the hilus it floats as an island in the calyx renalis, which enters deeply into the parenchym and forms a split covered with the thin epithelium on its surface. This split is essetially different from that around the medulary cylider of the aves, but resemble each other in their structures. M. sphincter papillae rises into the lumina of the calyx at the fornix ; so-called reabsorption theory of the calyx renalis may be easily explained by these morphological studies of the chiropteran kidney. There are special cells in the epithelium of the collecting tube at the outer zone of the chiropteran kidney.
