I call this species — 
Actinopteris Sengalensis, Fstm. 
Fronde orliculariter ovata, peltata,, ex foliolis singulis, segmenta farmantibus com- 
posit a; foliolis e media parte radiantibus, dichotome partitis, marginem versus latioribus, 
apice rotund atis ; loco insertinnis petioli medio. 
The whole frond is rather large, circularly ovate in outline, and the leaflets radiate 
towards the margin from the insertion of the stalk ; they are very well marked by a thin layer 
of coal, and are dichotomous in the same way as in Actinopteris radiata, Link. Not a 
moment’s doubt can exist as to this specimen being a fern. 
It seems to me different from those from Ehaetic strata, but is another proof of the me- 
sozoic character of our flora. From the upper coal measures in Australia there is men¬ 
tioned also “ a peculiar peltate leaf,” which may, perhaps, be also an Actinopteris, Schenk. 
(See Mines and Mineral Statistics of New South Wales, by John Lucas, etc., 1875, p. 129.) 
Besides the ferns already mentioned, some other forms occur, which, however, need not 
be noticed here, as they are not of any greater importance than those I have already described. 
I may, however, add that Pecopteris Lindleyana., Boyle, which has been noticed in relation 
with Pecopteris australis , Morr. (from Tasmania), belongs undoubtedly to the group of Ale- 
tlwpteris Whitbyensis, Gopp-, which seems to include only mesozoic forms; still another 
Pecopteris (Aletkopteris , Gopp.) is not uncommon, but this also exhibits a mesozoic habitus. 
Amongst the ferns we have therefore to note especially the following species :— 
Glossopteris indictt, Sehirnp., for the series. 
Gangamopteris cydopteroides, Fstm., for the relation of the Damiidas with 
the Talchir s. 
Tceniopteris danmoides, Mc’Clell. (Eoyle), and the other broad-leaved species of 
Tceniopteris from Kamthi for the mesozoic age of the Damn das. 
Neuropteris valida, Fstm., for the triassie (Buntsandstein) age of the 
Damiidas. 
Actinopteris Pengalensis , Fstm., mesozoic form. 
C.—C0NIFER2E. 
Coniferm are very rare in the Damiidas, but a very important genus has lately been 
found in the Kurhurbari coal-fields. 
a.— Voltzia. 
This genus is peculiar and limited to the middle and lower Trias as Schimper states.* 
Brongniart, the founder of this genus, was very well acquainted with it, and described four 
species, all from the Gres bigarre. 
On the large specimen from Kurhurbari, which I mentioned before when describing 
Neuropteris valida, Fstm., there are some branches of a coniferous plant, which, judging by
