The lowest sandstone lied discordantly overlies the Pakvozoic rocks 

 which show a northerly dii) Avith an ano-le of 35°. The agfo-lo- 

 merate-tntf encloses laruc blocks of andésite which are from the 

 Nosoko \olcano, aiid are dejjosited on its fringes ; and covers quite 

 concordantiv the limestone with alternatino- sandstone. The latter is 

 the same as that in Iriomote-iinia. and the a sfoflomerate-tuff contains 

 thin layers of this sandst(3ne. besides shale and a very hard quartzose 

 sandstone. Thus the above mentioned alternation of limestone and 

 sandstone is probably similar in age to the agglomerate- tuff, which 

 has been erupted from the N^osoko volcano. This tuff is not only 

 found along the northei'Ji side of the volcano, but also composes the 

 isolated hills near Tamatori-zaki. besides being exposed in small 

 patches in the neighborhood of Tnoda. In this rock there are 

 intercalated, in some places, thin lavers of bluish sandstone which 

 show the strike NoO" or E-W, and the dip SAV 2(f-4o° or 8 30°- 

 45°. Small exposui-es of the limestone, together wdth Pahcozoic 

 rocks, are foinnl on th<' coast near Inoda. A little to the south of 

 these exposures, then^ is a small region of Tertiary sediments wdth 

 andésite in contact, which forms a hill. These sediments are
