have we the marine sediments of the Upper Carboniferous age in complete 

 development ; it is also there that the Lower Carboniferous sediments appear 

 •to be developed to a notable extent. 



The most interesting fossils in the present collection are those of the 

 Permotriassic age, namely Pseudohalorites subglobosus Yabe and P. celestris 

 Yabe from Hsiang-tan hsien, Prov. Hu-nan, and Pseudomonotis griesbachi 

 Bittner var. concentrica Yabe from Tieh-shi-kou, Prov. Kiang-si ; these 

 occurrences show the extension of the Himalayan Permotriassic sea to the 

 interior of southern China. 



Perhaps already in latest Permian and surely in early Triassic, terrestrial 

 conditions prevailed in a part of the present provinces of Yun-nan and Fuh- 

 kien ; in these places we now find coal bearing deposits covering Permian 

 Fusulina limestones and containing Gigantopteris dentata flora. The dis- 

 tribution of this flora is not confined to these provinces, but extends to 

 northern Korea. On the other hand, there are also developed over an 

 extensive area of southern China the Lower and Middle Triassic marine 

 deposits in the so-called German facies, with Beneckeia and many forms of 

 Myophoria. Since the Rhaetic age, southern China has never been over- 

 flowed by marine water, but has remained in a terrestrial condition to the 

 present time, accordingly there are developed coal-bearing formations in the 

 Rhaetic-Liassic, Upper Jurassic and Lower Cretaceous ages, sometimes 

 occupying the same basin with the coal-bearing formation of the Permian 

 age. Only in the province of Yun-nan, does the Upper Triassic formation 

 comprise marine deposits with ammonites in open sea facies. 



Volumes I and II of this report, just published, contain detailed accounts, 

 in Japanese, of the geology and geography of the districts traversed by each 

 of the geologists despatched ; and in the last chapter of the first volume, Mr. 

 Noda gives a short, but concrete summary of all of the facts obtained by 

 them, taking into consideration also those previously known. In this most 

 valuable chapter, he distinguishes the following divisions in the geological 

 formations developed in southern China : ' .
