in a horizon higher than the shells, and are imbedded in a dark, soft, 

 often sandy, and at the same time micaceous, shale, easily splitting 

 into slabs. The state of preservation of the fossils leaves much to be 

 desu'cd, most of them being changed int(3 a black coaly substance. The 

 number of species which I could distinguish is 7, among which 

 Ciiparissidimii (?") japoïiicuni is by far the most abundant. 



2. Yuasa. 



In 18.S1, while I was engaged in reconnoitring the geology of 

 Kii, I discovered fossil plants on the northern shore of the lîay of 

 Yuasa, Yuasa being a town about 7 ri south of AVakayama. The 

 spot is locally known as Mizutani, and lies between low and high water 

 marks. Here a well stratified sandstone crops out from beneath the 

 water, steeply dipping towards the north. This sandstone passes ab(3ve 

 into a conglomerate overlaid by a dark-blue shale. The rock in which 

 I found the fossils is the sandstone. It is soft, fine-grained, greyish 

 to yellow, Ijrittle and often argillaceous, and easily splitting into thin 

 plates. The f jssils are generally in good preservation, but (jwing to the 

 brittle nature of the rock, large specimens are difiicult to obtain. The 

 number of species found is 13, among which recopteris Geijlerianü is 

 the most frequent. I obtained here also a species of Esther la. 



3. Sakamoto, Fujikawa, and Tanno. 



These three places all lie in the valley of the Katsuragawa, in 

 Awa, and very close to one another. The discoverer of the fossils was 

 my lamented colleague, the late Prof. Y. Kikuchi, who surveyed the 

 district in 1885. According to his report,'^ the valley is composed of the 

 Mesozfjic plant-bearing series, overlaid by the Cretaceous sandstone
