or E-W, S 30° in the vicinity of Haomi. Then along the southern 

 coast from Haemi to Kanokawa, the inclination is different. After 

 going about a mile to the west of Haemi, the rock oljserved is a fine- 

 grained sandstone, which shows various inclinations, until finally the 

 dip is due north. After this point and until Kanokawa is reached, we 

 find the strike and dip X 70°-80° E, NW 5°-25°, N 80° W, XE 20°, 

 or E-W, X 30°. From Kanokawa to the west of Ochimizu-zaki where 

 a thin coal-seam occurs, I found the strike to be nearly the same, 

 viz., E-AV and the dip X 20.° At Ubiraishi there is a calcareous 

 sandstone with fossil shells, closely resembling the rock on the north 

 of Urauchi. Then we enter the northern and western parts of a 

 tongue shaped region including the places called Yaeme-zaki, Xohama, 

 Sakiyama, Amitori, Funauke and Kuira-gawa. Here the Tertiary 

 rocks are very much disturbed, the dip and strike never remaining con- 

 stant even for a short distance; the coast is very deeply indented as is 

 shown in the plate. All these are perhaps due to a fault along the 

 south-western coast of the islets Uchi-banare and Hoka-banare. In 

 this region, which consists essentially of brownish sandstone, I have 

 found four thin coal-seams which can not be identified with those in 

 the main part of the island. The first seam is exposed at Xohama ; 

 the second runs from Sakiyama to the south of Amitori ; the third is 

 exposed on the south of Amitori; and the last is on the road from 

 Ubiraishi to Ochimizu-zaki. In the brownish sandstone are sometimes 

 found shale beds ; a calareous shell-bearing sandstone, probably a 

 continuation of that of Ubiraishi, is seen on the east of Funauke and 

 in Saba-zaki. 



Though the whole interior is almost entirely composed of Tertiary 

 rocks, they contain very few fossils. Except Litliothamnium and 

 Orbitoides and a few other Foraminifera found in the limestone, and 

 some indeterminable shells in the calcareous sandstone, I have found
