FORAMINIFERA IN THE RAISED REEFS OF FIJI. 355 



Singatoka. This place is situated on Viti Levu, which is the main 

 island of the Fiji Group and of a considerable size. It is largely com- 

 posed of volcanic rocks, and is much older than the smaller members of 

 the group. At Singatoka hard blue limestones, with a dip of 50°, under- 

 lie more friable limestones with a much lower dip (15°). The total 

 thickness of the beds approaches 1500 ft.
