greenish-grey sandy shale which passes into a shaly sandstone. It is 

 fine-grained and tolerably firm, Ijiit where it is exposed to air, it is 

 yellowish and more l^rittle. The plants are very well preserved. I 

 obtained 8 species, but principally Pecopteris Broivuiana, Zamiopliijllmu 

 Buchianum and Nilssonia scliauvihurgensis. 



The majority of the fossils from the above three localities are 

 those sent by Mr. Gyöken Otsuka of Kyöseki at the request of Prof. 

 Koto. 



Nathorst in his paper described also some from Yakyö, Ueno, 

 Torikubi, Otani, and Haginotani, places all in the neighbourh<iod of 

 Kyöseki. 



5. Kaisekiyama. 



This is a mountain north of Sakawa, also called Kompirayama 

 from a temple dedicated to Kom})ira standing on its top. The spot 

 where plants occur is on the southern flank of this miKintaiu, in a 

 soft, yellow, sandy shale, wdiere there are nnmerous impressions of 

 plants from which collection has been made partly by Mr. T. iSasa, 

 and partly by myself. The preservaticm is excellent, but the rock is 

 so soft and brittle that unless the greatest care is taken, the s})ecimens 

 are apt to fdl to pieces. The number of species which I could 

 distinguish from this locality anunuits to S, besides 1 variety, among 

 "vvhich l^ecoptcris Broicniana is the most abundant.

At this place close to the town of Sakawa a series of sandstones 

 and shales covers unconformal)ly a dark, compact, bituminous, 

 so-called Torinosu-limestone containing fossils wliich are referable 

 to the Malm.'^ T'he plants occur in shales which are ash-grey and
