4. Series of Marine Beds, with inlaid coal measures. This series 
consists of three groups : — 
a, Lower Marine Beds— containing marine animals. 
b, Lower Coal Measures— with plants, at Greta, Anvil Creek, Stony Creek, 
Raymond Terrace, &c. The plant-fossils are —

It is in these marine beds that Mr. R. 1). Oldham (see No. 59) dis- 
covered striated pebbles in those peculiar conglomeratic beds, the accumulation 
of which cannot be accounted for except by the action of ice floating in large 
masses. These conglomeratic beds are then strictly comparable with those of 
Bacchus Marsh (to be mentioned hereafter), and not, as hitherto supposed by 
me, the conglomerates at the base of the tlawkesbury rocks. 
I have also under No. 59 quoted Mr. "Wilkinson’s letter, dated Sydney, 
29tli September, 18S6, where reference is made to the above discovery. 
* This is quoted from Arowa, but it appears doubtful whether it really occurs there with Rliacopiai 
viikquilatcra = Otoptcris ovala, M‘Coy.
