the age of the Australian coal-beds.

District, New South Wales. Trans. Toy. Soo. Victoria, 18G5, Vol . VI., p. 27. 
Therein the Rev. Mr. Clarke lias treated of the same subject, with 
the intention of showing that the lower beds, containing Carboniferous 
animals, were conformable to the higher beds, with plant fossils, and that 
Glossoptcris beds were really intercalated with marine strata containing 
Palaeozoic fossils.

Baron dc Zigno modifies in this paper his communications about the 
Oolitic Flora. The greater portion of the Australian plants are correlated 
more closely with Triasic, and Liassic forms than with simply Oolitic.

The author gives at first a brief summary of the various divisions of 
the coal-bearing beds of New South Wales, as follows, in descending order : — 
700 to 800 feet.

Oil-bearing products (viz., cannel coal) have already been found in the 
third and fifth divisions.

forwarded by the Rev. W. B. Clarke. Quart. Joum. Geol. Soc., Vol. XX, p. 1, PI. I. 
This paper contains descriptions of three species of fishes from the 
Wianamatta and Ilawkesbury beds, viz., Paheoniscus, Cleithrolepis, and 
* The various papers to be quoted now are of greater and more positive importance than those named 
before, because they contain greater details about the several formations, and I would especially draw attention 
to them, because they will enable us to construct the general sequence of geological strata in New South Wales 
with regard to the plant fossils, and because from them it will be apparent which strata are to be correlated with 
those in the neighbouring provinces — in India and elsewhere.
