(1) Bluish gray hard limestones without macroscopic fossils, and dip- 
ping at steep angles. This was seen only in the Singatoka area, Viti 
Levu, where it underlies the bedded foraminiferal limestone. 
All the specimens of this have been forwarded to you, and this rock, 
as being probably the oldest hitherto observed in Fiji, should be worthy 
of careful microscopic examination. It may possibly have some relation 
to the Globigerina limestone of the Solomon Islands, and that recently 
brought to Sydney by Mr. Danvers Power from Noumea in New Caledonia, 
which is also a Globigerina limestone. 
(2) Volcanic rocks, such as spherulitic rhyolites and diabasic dolerites, 
which must have supplied the well-rolled pebbles in the conglomerates 
of the Fiji soapstones. 
(3) (a) “ Bedded limestones.” These are developed, as observed, by 
Mr. Andrews chiefly at the Singatoka area. Their angle of dip is 15°, 
and they are largely foraminiferal (forms like Amphistegina, Globigerina, 
Textularia, etc., being well represented), mixed with fragments of nulli- 
pores, gastropod and lamellibranch shells, polyzoal skeletons, fragments 
of echinus spines, etc. As you will see from the specimens sent, this is 
distinctly not a coralline limestone, but rather a foraminiferal nullipore 
rock. If the planes of bedding represent originally horizontal planes 
which have been subsequently tilted so that they now dip at 15°, the 
thickness of these bedded limestones at the Singatoka area, as measured 
by Mr. Andrews, cannot be much less than 1500 feet. 
Outcrops of similar limestones have been observed by Mr. Andrews at 
the raised atoll of Mba Vatu, Vanua Mbalavu, in the Lau Group, where 
they form the foundation rock upon which the raised limestone rock 
rests. 
(6) Calcareous fossiliferous volcanic conglomerates probably passing 
in places into the “soapstone” formation of Fiji, the latter bemg a 
foraminiferal submarine volcanic tuff and tufaceous foraminiferal mud- 
stone. 
These may be slightly newer than, or possibly contemporaneous with, 
the foraminiferal ‘‘ bedded limestones” of the Singatoka area. 
In the Lau Group they are seen at Mango, where, as shown on the 
left-hand side of the upper of Mr. Andrews’ sections, they form the basal 
rock on which the raised reef limestone rests (Plate 2). 
A thickness of only about four feet is exposed at Mango. They ap- 
pear to be associated in places at Mango, as observed by Mr. Andrews, 
with a steatitic fine basic tufaceous rock, homotaxial perhaps with the 
Suva “ soapstone.”
