Bracliiopoila-beds' from the frcquoricy of those two species. This is the more 

 striking as other fossils are comparatively rare ami liclouy; ouly to 5 species, viz. 

 Pecteu laetus Gould, liima S(]uaraosa I.amarek, Ostrea gig;xs Thnnberg, Ostrea 

 (len.^elamellosa Lisohke ami Anomia patcllifoniiis Liniie. Tlie identity of the 

 formation, however, is evidently proved hy the similarity of the rocks to 

 those near the coast, and by the species of shells ; fur they are all recent Japanese 

 and uith one exceiition found also at Oji, Takigashira £c. 



Among the other fossils some sca-iirchins might be mentioned, and some 

 fragments of fossilized wood p.artly reaching luige dimensions. Unfortunately, 

 they are all too badly preserved to be of any importance. 



In concluding the remarks about Hidachi, I have to mention a locality on 

 the road from Tokio to Mito, ne.ir the Toneg.nva and next to the village of 

 Kogone. This locality is included within the compass of the Tokio environs, 

 but its formations are intermedi.ite between those of Tokio and those of Hidachi. 

 They consist of a tufaceous sandstone, very much like that of Sukegawa, only a 

 little softer. It is covered l)y diluvial strata, mostly also sandy. From the 

 tertiary strata Mactra veneriformis Desh., Cythorea raeretrix L , Area iaflata 

 Reeve were brought to me. 



LOCALITIES ON TUE ISLAND OF KIL'SIC. 



The thick and varied system of sandstones, tufas, conglomerate and shale 

 which is seen along the coast on both sides of the Tokio plain as well as in the 

 hills surrounding it, is, of course, not limited to central Japan. I am fully con- 

 vinced that it will be discovered almost along the whole eastern and southern 

 shore, and probably it does not end there. To the south and west, this may be 

 said to a certainty; for in the island of Kiusiu several places are already known 

 and have been explored which doubtlessly cont^iin the same formation. 



At Amakusa, tufaceous rocks, somewhat fine-drained, contain a great many 

 moulds of bivalves — Tellina nas\ita Conr., Tapes rigidus Gould, Pecten plica L., 

 JIactra Sachalinensis Schreuck, Dijjlodonta trigonula Desh., Area granosa L., 

 Cardium Californiense Desh., Saxidomus purpuratus Sow.— and moulds and shells 

 of Turritella communis Risso. 



In the ken of Kagoshima the amount of tertiary fossils is still larger, though 

 we cannot include in tliis formation all the layers of plants frequently funnil iti 

 tliis part and in other districts of the island; fur some of them are rpiateruary 

 and belong to very modern fresh-water deposits. The fossil shells are Niissa 

 livescens Phil., Natica pyriformis Recluz, Lampania zonalis Lamarck, Tellina 

 pa.suta Conr., Mactra vcnerifonnis Desh., Cytherea meretrix L., Cardium Califor- 

 niense Desh., all tlie three Arae descriljcd alwvc and both species of oysters. 



Near Bungo, on the nortbea-stern corner of the island, blocks with Dosinia 

 exoleta L., Mactra veneriforraia Desh., Saxidomus purpuratus Sow. and Cardium 

 Californiense Desh. arc found.
