Bacchus Marsh Sandstones .—“ Now, perhaps, tlie Bacchus Marsh sand¬ 
stones hare to bo placed as above or partly on the horizon of tho Newcastle 
beds. They niay, perhaps, also bo called the ‘ Gangamopteris beds as so far 
as I could inform myself, they contain Gangamopteris only (coming in this 
very close to our Talcrnr group, underlying the Coal-beds where Gangarao- 
pteris preponderates). 
The species described from hero aro :— 
Gangamopteris angustifolia, M‘Coy 
„ spathulala „ 
„ obliqua „ 
‘‘If this position is correctly assigned, then the Indian coal flora (with Glossop- 
teris) is a third re-appearance or the Australian Lower flora, in tho Upper 
Marine beds, as in column marked h in the 1 Systematic Table.’” 
Hawkesbury and Wianamatta Beds. —Dr. Feistmantel makes the following 
observations respecting these:—“Although representing, perhaps, strnti- 
grapliically two groups, they seem to me, from a palaeontological point of view, 
to be of tho same age, or very nearly so. It is true they contain fishes, some 
of which (one, Paicconiscus) are heterocercal, but another one seems not 
hctorocercal ( Cleitholepis gramdatus) —[But Egerton distinctly calls it 
heteroc.—W.B.C.]—while of the third one tho tail is not known. If we now 
take into consideration that a Paicconiscus is known from the Karoo beds in 
South Africa, which are more than probably Trias, and if we consider that 
a Paicconiscus superstes, Eg., is described from Keuper in England, then we 
must not be astonished that a l } alctoniscus should be found in these Ilawkcs- 
bury and Wianamatta beds, which I would consider Upper Tnassic (although 
the plants by themselves would justify to consider these beds as on the horizon 
of the Rhaetic between Keuper and Lias). These are all 1 could determine 
or get information of.” 
Jurassic or Highest Beds. —Dr. Feistmantel writes :—“ There is one 
point not quite clear to me, if that Olossopteris which Professor M‘Cov 
( ( Prodomus”J and Mr. B. Smyth ("'Report of Progress”) mention as occurring 
in one specimen together with Pccopicris Australis, Morr., from Tasmania, 
belongs also to this group of strata.” 
General Remarks. —Dr. Feistmantel romarks, with reference to India, “It 
always results moro and more that our Coal-bearing strata are only ‘ plant - 
bearing ’ ; no Marino fossils are here. Always more evidence is procured for 
Triassic age of the Coal Measures, and there is no other ovidonco for tho view 
of their probably Upper Paloeozoic age than the genorieal affinity of some 
plants, as Verlebraria, Phgllotheca, and Olossopteris , with the Newcastle beds, 
and partly in 6ome of your Lower beds. As I have once before mentioned, 
you may have every reason for an * Upper Pakeozoic ’ ago of your Newcastle 
beds, but there is nothing of this sort in our Indian Coal-seams. 
“ As I mentioned also before, our Indian Coal Measures are underlaid by 
tlio so called Talchir group, and another group of Coal-seams which I dis¬ 
covered and proved in two Coal-basins (in Kurhurbali, in Bengal, and Mohpani, 
in the Sutpura Basin), which are characterised by the preponderance of Gango 
mopteris, by tho absence (orrareness) of Verlebraria , by the rareness of Glossop- 
teris , which reminds strongly of the Bacchus Marsh sandstones. If it would 
be proved that the Bacchus Marsh sandstones aro on the horizon of your 
Newcastle bods or tho termination of them, then our Coal flora of India would
