Furet has studied the fossils in the limestone and clay in the 

 southern part of Okinawa-jima (Die Physikalischen Verhältnisse der 

 Lutschu-Inseln. — Vetcmianiis Mlttheihingen^ 1860, p. 156) and found 

 in the limestone near Xapha (Xaha) and Tkiatung (?) the following 

 eleven species: 



Honicidaris sp, Vecleii ae<piiralrif>, 



Vecten sp, Pecten quinqw'costahis Î, 



Pholadomia sp. Isocardiiim sp, 



Ferna sp /. Tcrehmtida ohovata., 



Ävicula up /, Gerithium nudmii, 



Fnsiis sp. 

 He also mentions the following nine species as taken from the 

 cL'iy in the south of Xapha: 



(Jlica clavida. Natica cepacea^ 



Fectuncuiiis aeqviralcis^ Östren ßahelloides, 



Area sp, Fiisus neucomiensis, 



Spondijhis Kp, Flicatida sp, 



Ostrca niarsliii. 

 He seems therefore to have reo-arded the formation as belong-ino- 

 to the upper part of the Mesozoic group. 



A long time after the publicati<m of the above two works, Prof. 

 Döderlein* in 1S(S() made a two-weeks trip to Oshima (in the Oshima 

 group). He started from Xase on the west coast on August 16th, and 

 first travelled on foot through the island over Yuwan, Xagara and Knji, 

 following the shortest route. He then passed over to the next island,
