Biologically the material now at hand comprises fossils belonging- to 

 very varied groups : it includes calcareous algae, fern-like plants, spheno- 

 phyllales, equisetales and cycads among the plants ; and foraminiferas, 

 corals, brachiopods, bryozoas, molluscs and trilobites among the animals. 

 Of these fossils. Palaeozoic corals — together with those from Northern China, 

 Japan and Korea — have been studied by myself since 19 12, in collaboration 

 with Mr. I. Hayasaka ; the full accounts of these fossils will be given in a 

 paper entitled " Palaeozoic Corals from Japan, Corea and China " which will 

 apear in the near future in the Science Reports of the Tohoku Imperial 

 University, Second Series Geology. To this collaborator was also offered the 

 study of the brachiopods which form an essential part of the present material, 

 these brachiopods — all of the Palaeozoic age — have been worked out in 

 connection with his study in a wider scope, comprising all the Palaeozoic 

 brachiopods from Southern and Northern China, Japan and Corea ; and his 

 results, as a whole, will be published also in the near future in the same 

 Science Reports.^' The descriptions of all other fossils in the present report 

 together with some geological statements of general interest and a summary 

 of our previous knowledge concerning the palaeontology and geology of 

 China are my contributions. 



Geologically the present material comprises fossils ranging in ages from 

 Cambrian to Jurassic, those of the Permian age being most numerous among 

 them. From Southern China, some Lower Cretaceous plants and fresh water 

 shells have lately been described by M. Yokoyama'-' and Frech,^' numerous

 all these parts also will soon or later and in modified or unmodified form be published in the said 

 Science Reports. 



2) Yamada collected some plant fossils from Shi-kuan-tsu in Chao-hua-hsien and Sha-chi- 

 miao in Ho-chou, both in Prov. Sse-ch'uan: these Yokoyama assigned to the Lower Cretaceous age ; 

 they are : —

3) Cremer found some fresh water bivalves in a coal bearing formation developed at Li- 

 tschong-yuan along the Yang-tse-kiang, 5 li above Fu-tschou, Tshung-king-fu, Prov. Sse-clvuan; 

 Freeh who described tijese fossils under the name Unio cremeri Freeh, U. j. bohmi Freeh and 

 Cyrena (Miodon) cf. kiliani believed the age of the formation to be the lower Cretaceous. Freeh:
