Comparative studies were carried out on the anatomy of teeth of Japanese Reptilia (Gecko japonicus, Thakydromus thahydromoides, Elaphe climacophola, Eumucus latiscutatus.), and Amphibia (Rana nigromaculata, Hynobius nebulos, Diemyctylus pyrrlogaster) with special reference to their distribution, their contour and their implantation. These observations were summarized as follows. 1) Distribution of teeth. The teeth were equally distributed on the maxillar and praemaxillar in all reptilian and Amphibian animals studied. The vomer had teeth in Amphibia but not in Reptilia. It was Elaphe climacophola in Reptilia that had teeth on the pterygoid and palatal bone. All the teeth implanted on these bones were arranged in a single row. 2) Contour of teeth. In Reptilia the contour of teeth differed between four Kinds of animals studied, that is, those of Diemyctylus pyrrlogaster were nearly conical, those of Takhydromus tachydromoidia were like triangular cone, those of Eumucus latiscutatus were wedge like, and those of Elaphe climacophola exhibited sharp and long conical shape, while in Amphibia, the teeth of each species exhibited nearly the same curved conical contour. 3) Implantation of teeth. Both amphibian and reptilian animals except Elaphe climacophola exhibited one-sided row of teeth on the bony process, while the teeth in Elaphe climacophola were seated at the top of the bony-process. The teeth of all the animals studied were connected to the bones by means of tooth sockets.
