basi racliantibus (Cyclopteridis instar), anastomosantibus, rctia longiuscula 
ac latiuscula media in folii parte, sed angustissima marginem versus forman- 
tibus (Glossopteridis instar) ; basi attenuante, amplexicauli. 
Ohs . — This is the commonest form in the Talchir and Karharbari beds 
in India, and it there represents M £ Coy’s Gangamopteris obliqua, from the 
Bacchus Marsh beds in Victoria. 
Locality and Horizon . — I have recognized the same species amongst 
the fossils from the Mersey Coal beds in Tasmania. 
In the same beds there occurred also two varieties of the same species, 
which are also frequent in the Talchir and Karharbari beds in India, viz. : — 
Gangamopte ris cyclopteroides, var. attenuata. 
Feistmantel, loc. cit., 1879, p. 14, ct figs. 
Gangamopteris cyclopteroides, var. subauriculata. 
Feistmantel, loc cit., 1879, p. 13, ct figs. 
These forms now aid considerably in correlating the Mersey beds with 
the Talchir and Karharbari beds.

S'p. Char . — Pronde lata, insequilatera, obliqua, basim versus sensim 
attenuante ; basi oblique truncata sessili. 
‘•'Wide, inequilateral, oblique, subtrigonal, widest near the broadly 
distal end, gradually tapering towards the base, which is not petiolate, but 
obliquely truncated, with a moderately wide sessile base of attachment ; 
length commonly about 4 or 5 inches, width near apex about 3.1 inches, width 
near base commonly about 9 lines.” 
Locality and. Horizon . — “ This is the most variable and common of 
the three forms abundant in the sandstone quarries of Bacchus Marsh, 
Victoria” (? Permian). It is also found in the Mersey coal beds, and at 
Porter Hill, near TIobart, Tasmania (? Permian).
