As to the stratigraphic succession and zoning of the Gotlandian and Devonian deposits in Japan, we have had only the conceptive explanations., The writer wishes to make them clear in detail on the basis of the following standard succession : The Gotlandian and Devonian deposits in this district, called the Takainari System by the writer, may be classified into four groups, basing upon the lithologic characters., They are summarized and tabulated in Table 1., For the evidence of the geologic age of the Takainari System, we have hitherto found the Middle Devonian and the Middle Gotlandian faunas from the III Group and I Group respectively., The relations between the Takainari System and the Lower Carboniferous have not yet been clearly determined for the absence of the Upper Devonian index fossils, and the base of the Takainari System is indiscernible by the granitic intrusion.,
