Formations of New South Wales. 349 
In New Zealand the greater part of the Coal measures is 
not Paleozoic, but some of it is said to be Secondary, to which 
epoch also belong the Jurassic Plesiosaurus and Ammonites ; 
and Triassic Avicule and Monotis. 
In New Caledonia, there is also a distinct Triassic series, of 
which some of the fossils are akin to those of New Zealand. 
But, at present, neither has this nor the Belemnites of Queens- 
la n found in New South Wales. 
So far as the question of Coal is concerned, no Coal seams 
(but only thin patches or very limited layers) have been found 
in the Wianamatta or the Hawkesbury rocks, that can be com- 
pared even with the alleged Secondary deposits of Victoria ; 
and in Queensland, where workable seams do exist, the fossils 
of New South Wales are also found. In the Secondary marine 
beds of Wollumbilla and the Amby, gold in minute visible 
particles was found by me in some of the quartz pebbles ce- 
mented with the shells, and a small quantity was detected by 
crushing the whole, shells, pebbles, and the calcareous cement

such deposits. But some of the leaves are supposed to represent 
among others the foliage of Fagus ; yet, it was only in 1866
