sandy, aiifl easily 8|)lit into thin ])latcs. Tho only species which 

 I could find in a collection made l)y Mr. Xasa is that already des- 

 cribed by Xatliorst, viz., l\'copten'>; Broirniatia. However from the 

 specimens, which are ])resent in large nnmbers, I could convince 

 m^^self how variable the form of the ])innules is in different parts 

 of the frond. In the nnderlyino' limestone we find also now and 

 then impressions of plants which have been very probably drifted 

 into it. I have been aljle to distino'uish only two forms, one a 

 Cliladojihkhis, and the other a Nilssom'a resembling y. ptcrophyUoidef^. 

 However, owing to their unfavourable state of preservation precise 

 determination is not possible. 



7. Chöja. 



Chöja is a mountain village in the valley of the Shiraisliigawa, 

 many kilometers to the west of Sakawa. I got only a single ])iece of 

 stone from this locality, collected ])y ^Ir. Toyama, a zealous collector of 

 fossils at Sakawa. It is an ash-grey sandy shale, quite similar to that 

 of Yoshida-yashiki, and contains also only a single species, Fccoptens 

 Broiniiana. According to Toyama and others, a limestone occurs in 

 the locality. 



Conclusion. 



The number of fossils which I liave been able to obtain from the 

 above enumerated places amourits to 24 species and 1 variety. Of 

 these 24 species, 28 are jjlants and 1 a ])h3'llopod. Adding to these, 

 3 species and 1 variety described by Xathorst, viz. Macrotceniiiteris 

 mcmjinata, Lj/copodites sp., rtilophijlhim cf. cutchoise and Podozamites 

 lanceolatus var. latifolia, the total number becomes '2ß species and 2 

 varieties of plants, and I species of animal, lîefore proceeding, however 

 directly to the conclusion which is to be drawn from the occurrence
