3 .—A new Gangamopteris from the Kamthi beds and another front Karharbdri. 
Of tlie genus Gangamopteris, which McCoy established for some transitions forms 
between Cgdopteris and Glossopteris, I described already one species in my first note on 
the flora of the Damndas and the Talchir group: I called it Ganqamopt. egclopteroid.es, 
Fstm.,* on account of the more Cyclopieris -like form of the leaf. From the occurrence of 
this species both in the Barakar and Talchir groups, I draw the conclusion that these 
groups are both of the same age, as the Talchir group contained little else than this 
species. McCoy described it first from some rocks in Victoria, where no marine fossils 
occur, but where Tmriopteris Daintreei, McCoy, is found, which latter in Queensland is 
considered as characteristic of the mesozoic beds there. With these also Phyllotheca Aus¬ 
tralis, McCoy, occurred in Victoria, 
Mow I have also from the Kamthi beds very closely allied forms ;f they are, however, 
much smaller, seem to have a thicker substance, thicker veins and wider venations, so that 
I will describe it as a species of its own. Another species, brought lately by Mr. Wood- 
Mason, I mention further in the note on the fossils he brought from Raniganj. 
GahGamopteris Hughesi, Fstm. 
Fronde simp/ici, rotunde ovali, sub coriarea basi tit nidelur subcordata, margine 
intergra, medioenter lonr/a, marimo sped mine 10-1.1 cm. tonga, 5 cm. la to; rhachide 
vet. nemo medio radio; nereis radiatim c basi usque ad marginem eurrentibus, arcuatis, 
non mi tie mediis, omnibus parte inferiori craseioribus, dehinc omnibus repetito furcatis 
anastomosantibus retia lutiora, breviura forniuntibus. 
I have called this form after Mr. Hughes of our Survey, who has already collected a 
great many of interesting fossils from the Damuda series. 
Although describing this fossil b} T a name of its own, I yet believe it related with that 
species from the lower Damndas and the Talchir group, i. e., Gangamopt. cyclopte- 
roicles, Fstin. 
This again supports, what I have already supposed, that all the three sub-groups of the 
Damndas, although in reality existing, are yet of the same age, and that the Talchir 
group too is to he subnamed m tins epoch. 
Another form must be noticed from the Karharbdri coal-field , it is— 
Gangamopteris angttstifolia, McCoy. 
IS . Ci/clopleris august folia. Me oy : Annuls and Magaz. of Nat. Hist., Vol. 20. 
IS . &avgamoplerit anguttifolia, McCoy : Prodrome of Pateontology of Victoria. Des. 
Amongst those specimens which, as I already mentioned several times, Dr. Stoliczka 
Pro u tv hi from Karharbdri coal-field, is also a specimen which already at that time was 
determined as C/clopl. august folia, McCoy, which, however, is now by McCoy himself 
ranged with Gangamopteris, McCoy. 
This Gangamopteris is in Victoria found in certainly mesozoic rocks, being associated 
with Tceniopteris Daintreei, McCoy, which is characteristic of mesozoic rocks in Queens¬ 
land.+
