'i'iie iiiociit.iiiis in titc noilli oi llic Tokio |)laiii. l>or<lering the ft.-.\, are next 

 to \k nu'iitioncil. The exposures of tertiary Ik-hIs arc chiefly found n!on^ the 

 coast at some distance from Mifo. In a few places hrown coal occurs, a« it sivms, 

 nndiT the UhIs described liere, and it is said to extend even into the sea. Tho 

 fiissiliferous strata liclong to a very thick system of [»artly hard, partly softer 

 sjindstones, sometimes n little tufaceons, biit ninth oftenor somewhat marly nml 

 intermixed with small rounded grains of rocks from the nei;^hlH>uring cryslntlinu 

 nioimtains. In one instance, these tertiary nKks are en.-l(;8etl within the schistose 

 crystalline roeks and form a separjite b:Lsin; this is the c;isc upwards, or wt-st, of 

 Sukegawa. In all the other Cixscs, for instance cast of Sukegawa. oral Tagagori, 

 ^liyaku, they form the very hust solid rotks next to the sea. They arc covered 

 by diluvial strata uuieh in the same way as at Tokio, and it is worthy of notice 

 that these diluvial strata are always horizontil. whilst the dip of tho tertiary 

 strata, as has liccn stated above, is mostly Ixitween 8" and If)". 



The fossils themselves are numerous but very often too badly prewrve«! to 

 lie detennined. It seems the less to lie neccssjiry to describe tlieni here comple- 

 tely, as they will be tlic object of another jxijier prcpaa'd by Mr. Kochilx-, 

 gnubiate and ex-assistant of the Daigaku, now ap[)nintc<1 at tho Geologicnl 

 Surveyiii;.;-Ofli(e of Tokio. Rut in order to give a < ' i of the fauna in
