JUEASSIC PLANTS FROM KAGA, HIDA, AND ECHIZEN. 



1) 



(3.) Oz7j (Prov. Kaga) on the Ozögawa, a branch of the Tetori- 

 gawa, about 3 ri (12 kilom.) in direct distance X.E. of Shimamura, 

 and 370 m. above the sea-level. Here the fossils are found mainly in 

 black carbonaceous, partly micaceous, sandy shale, from which the 

 plants, which are also black, can hardly be distinguished, unless by 

 their more shining colour ; and partly in highly micaceous dark 

 sandstone, which may be considered as differing from the shale in 

 having less clay admixed. 



At Setomura, a village lying between this place and Kinameri, 

 Mr. Kochibe observed the following series of rocks : 



a. Siliceous Sandstone, grey and medium-grained, underlayed by 



b. Marly Conglomerate. The pebbles composing this rock are 

 partly of limestone, which is often dissolved out, leaving cavities. 

 The solution penetrates amongst the combining medium, making the 

 rock harder and harder. 



c. Black Shale, which is the lowest, probably corresponding to 

 the fossil bearing rock of Ozö. 



(4.) Hakogase (Prov. Echizen), situated in the upper valley of 

 the Kudzuriugawa, very near the boundary of Mino, and about 10 ri 

 (39 kilom.) S.E. of the town of Ono. The strata are somewhat ir- 

 regular, but generally strike N.W. with dip, varying from a very 

 gentle one to up to 70° at Mochiana. The following is a section along 

 the Ishidoshirogawa from Maezaka (529 m.) to Asahi (430 m.), a 

 distance of 2 ri (7.8 kilom*) 



Nochino.
