254 The American Geologist. April, 1902. 
The first knowledge of the natural history of the Riukiu curve is 
due to the American expedition under Commodore Perry, 1852-1854, 
in whose report is a sub-report by R. G. Jones, giving some geological 
descriptions of the “island of Great Lew Chew.” Later studies have 
been by Furet who regarded the formation, as indicated by fossils, as 
belonging to the upper part of the Mesozoic. Déderlein, in 1880, after 
two weeks’ travel in the interior of the islands in the Oshima group, 
thought that the formation consisted of Archean rocks chiefly 
granulyte and gneiss. Several Japanese geologists have more recently 
reported on some parts of this “curve,” and on the geology of the 
northern part of Taiwan. 
In general, the author has concluded that these islands consist 
chiefly of Paleozoic rocks having a steady dip northwestward, toward 
the China sea. They rise sometimes over 1,500 feet above the sea. 
Westward from the axis of the curve is a series of volcanic islands, 
located as supposed, along a great fissure, which seems to extend a 
great distance further southwest, while eastward from the axis is 
found an outer sedimentary zone made up of Tertiary sediments, the 
older portion of which is toward the south. These parts are called the 
“inner neovolcanic belt,” the “median Paleozoic belt,” and the “outer 
Tertiary belt.’ These, according to Prof. Koto, coincide with those 
in the peninsula of Malaca, the Andaman isles, and the Nicobar isles 
in the Indian ocean, with the Banda isles in the East Indies, and with 
the Lesser Antilles in the West Indies. 
This paper consists of a summary statement of results. Its weak- 
est feature is that it gives none of the paleontological data on which 
was based the determination of the age of the Paleozoic rocks. It is, 
however, a very valuable contribution to the geology of the Japanese 
empire. NW. We
