LAND SHELLS OF THE OKI ISLANDS, JAPAN, 



BY H. A. PILSBRY AND Y. HIRASE. 



The Oki Islands, in the Sea of Japan north of western Hondo, 

 consist of one large and three smaller islands and several islets, the

 of about 10 miles. The highest elevation is said to be about 

 1700 feet. 



The mollusks of Oki have not before been noticed.
