Ohs . — This is a long, narrow loaf, with a distinct midrib with once o 
twice anastomosing secondary veins. I cannot say whether it was a single 
leaf or otherwise. 
Locality and Horizon . — In the Newcastle beds at Blackman’s Swamp, 
New South Wales (? Permian). 
Genus — GAN GAMOPTEBIS, J/‘ Coy.

Gen. Char. — Pronde simplici (an impare pinnata ?), forma variabili, 
nnne ovali, latiuscnla, nunc obovato elongate, basi attenuata, amplcxicauli 
an subauriculata, nunc lanceolato-spatlmlata, truncata ; nervo medio (dis- 
tincto) nullo, omnibus nervis ex basi radiantibus anastomosantibus, retia varia 
formantibus ; fructiticatione adhuc ignota. 
Ohs. — The first species of this genus was described, in lSf-7, by Prof. 
M £ Coy as Cyclopteris (?) angustifolia ;* butM'Coy has rightly observed that, 
though the venation has the general distribution like a Cyclopteris, yet it differs 
by constant anastomosing of the veins. Later he formed the genus Ganga- 
mopieris, f and in 1875 he illustrated it especially from specimens from the 
Bacchus Marsh Beds in Victoria, where representatives of this genus arc the 
only fossils known. 
But the same genus also occurs in the Newcastle beds in New 
South Wales ; and it is also very frequent in the Mersey beds in Tasmania, 
where it is found together with species of the genus Glossopteris. Under 
quite similar circumstances it occurs in India in the Talchir Shales, and in 
the Karharbari coal beds. 
It was especially upon this occurrence that I have, in my original 
work on the Australian Plora (1S7S, p. 101), based the correlation of the 
plant beds in India and Australia (Victoria and New South Wales). It was 
* From Guntawang, near Mudgee, New South Wales (Upper Coal Measures). 
t [The correct date of this genus is 1861. It was first proposed in a paper by Prof M‘Coy — “A Communi- 
cation made by the Kev. W. B. Clarke, &e., on Professor M'Coy’s new Tceniop/eris ” (Trans. It. Soc. I 'ict 18C0 
[1861], p. 107, note.) — K. E., jun.]
