| Abstract. | 
Tus paper, though dealing principally with the relation to one 
another of the different Palzeozoic coalfields of New South Wales, 
describes also the author’s views with regard to the probable 
relation of the Paleozoic and Mesozoic coal measures of New 
South Wales to those, when represented, of Queensland, Victoria, 
New Zealand, and Tasmania. The coal-bearing strata of New 
South Wales belong to three distinct systems. 
lst System.—The first system, probably of Lower Carboniferous. 
age, has not yet been proved to contain workable seams. Two 
seams, however, 5ft. and 7ft. thick respectively, occur near the 
top of this system, but the coal in both is too dirty and full of 
bands to be marketable. 
Both of these seams occur in the Rhacopteris series overlying 
the Lefidodendron beds, of which, however, they form a part, and 
this series is separated by a vast interval of time, as evidenced by 
a strong break in the flora, from the overlying Permo-Carboniferous 
system. 
The Lepidodendron beds of New South Wales are considered to 
be the equivalents of the Avon River sandstone in Victoria, and 
of the Star Basin and Drummond Range beds in Queensland. 
The observations of Professor McCoy that the Zepzdodendron of 
the Avon River in Victoria was not the Devonian variety—Lepr- 
dodendron nothum—but a variety of possible Lower Carboniferous 
age, is quite in accord with the recent observations of geologists 
in New South Wales, no true specimens of the above-mentioned 
plant, in the opinion of Mr. R. Etheridge, jun., having ever been 
found in New South Wales.
