ON SOME FOSSILS FROM THE ISLANDS OF FORMOSA & RIU-KIU. 15 



Operculinse it has yielded numerous other species of Foraminifera 

 as will be seen from the appended " Tabular Statement of Deter- 

 minations." 



Occurrence : Itoman, Southern Okinawa, Riü-Kiü Islands. 



Carpenteria, sp. (PI. II, fig. 3 ; PI. Ill, fig. 6.) 



The genus Carpenteria has played an important part in 

 building up the Orbitoidal-limestone of Iriomoté Island. Frag- 

 ments are very numerous in the sections and possibly two or 

 more species are present. We have however not had sufficient 

 material at our disposal to satisfy us in referring our examples to 

 definite " species." The specimen shown in PI. II, fig. 3 appears 

 to bear a strong resemblance to the Carpenteria capitata described 

 by Messrs. Jones and Chapman from the Tertiary limestones of 

 Christmas Island (Monograph of Christmas Island, p. 246, PI. 

 XX, fig. 7). The specimen figured on Plate III, fig. 6, does 

 not at first sight look like a Carpenteria, but from numerous 

 specimens in our slides connecting it with undoubted examples 

 of the genus there can be no question as to its affinities. 



Occurrence : Iriomoté limestone, Riri-Kiü Islands. 



Linderina, sp. ? (PI. I, fig. 2). 



We are in some doubt as to the proper affinities of the 

 organism represented in the figure quoted above. It certainly 

 bears a very striking resemblance to the horizontal section of 

 Linderina brugesi Schlumberger, as figured by M. Schlum- 

 berger (Bull. Soc. géol. France, 1893, Sér. Ill, Vol. XXI, PI. 

 Ill, fig. 9) ; and in the Orbitoidal limestones of Gomanton Hill,
