FORAMINIFERA IN THE RAISED REEFS OF FIJI. ail 
Vatu Vara. Of purely limestone composition. The island forms a 
steep pyramid 1050 feet high, surrounded by a broad flat. At least 
four periods of elevation are shown by terraces (three) and beach lines 
at the 800 ft., 600 to 700 ft., 350 ft., 25 and 15 ft. levels. 
500 ft. Organisms are few in number and very indistinct. Corals, a 
gasteropod, Lithothamnion, and Carpenteria fragments are recognizable. 
Foraminifera : CARPENTERIA. 
309, No. Fv.v., ht. 650 ft. The organisms have been quite de- 
stroyed by dolomitization. Lithothamnion is indicated by certain dark 
patches. 
1000 ft. Lithothamnion and echinoderm fragments. Corals. 
Foraminifera : GyYPsINa. 
Nummuloid form. There are numerous shattered specimens of un- 
certain genus, possibly Heterostegina. 
Namuxka. A small island composed entirely of limestone. It must 
not be confused with Nomuka, which is in the Tonga Group. 
30 ft. This rock is of considerable interest as, with the exception of 
that from Mango, 310 ft., it is the only one containing Orbitoides. 
The specimen is too indistinct to enable the species to be determined, 
but the rock is shown by its presence to be not younger than the 
Miocene. Lithothamnion occurs. All the organisms are altered. 
Foraminifera : ORBITOIDES, 
ORBITOLITES, One very indistinct specimen. 
1 ANOMALINA. 
75 ft. This rock much resembles the last. It contains Lithotham- 
nion and the following :— 
Foraminifera: ORBITOLITES. 
Rotaline form. 
162 ft. A much altered rock. Lithothamnion and Polytrema are 
the only organisms recognizable. 
Foraminifera: PoLYTREMA. 
YatHata. Partly of volcanic origin. The flat top of the island is 
840 ft. above sea level and is the highest of six terraces. 
800 ft. The organisms are in a fragmentary condition. They 
include corals, echinoderms, Lithothamnion, and Foraminifera. 
Foraminifera : PoLyTREMA, growing attached to Lithothamnion. 
CaRPENTERIA.
