the form of the leaves, can only belong to the genus Voltzia, Brgt. Our specimen agrees best 
with the following :— 
Voltzia acutifolia Brgt. 
1838. Broil srniart: Prodroraus, pp. 108,190. 
1814. Schtaipor et Morjgcot : Monooraphie, etc., p. 20, Tab. XV. 
1871-72. Schimper : Palirontologie rSgat, p. 211, Vol. II. 
"When I compare our species with V. acutifolia, Brgt., I must also add that the leaves, 
especially towards the end of the branches, are a little longer and broader. Voltz. acutifolia, 
Brgt., is, with Voltz. heterophylla, Brgt., most characteristic of the Gres Bigarre. 
Besides this distinct Voltzia thereis also a branch, with much longer and broader leaves, 
which I cannot identify with any known Voltzia, but rather with Alhertia speciosa, 
Scliimp. (see Schimper and Mougeot, 1. e. PI. V, f. B), which is also a well known species 
characteristic of Lower Trias. 
This is all that need now be said about the Conferee. 
The above are tbe most important plant remains from tbe Damudas, so far as they 
have hitherto been determined, and no further discussion is necessary in this paper, as 
sufficient evidence has been brought forward for tbe determination of tbe age. 
Prom the previous discussions I have been led to tbe following results:— 
a. —i ScJiizoneura is represented by' the same species (ScJiizoneura Gondwanensis, Fstm.), 
in tbe Pauchet group and in the Damiidas, especially in tbe Upper Damudas, or 
Banigan j, proving that both belong to tbe same general epoch. 
b. —The occurrence of Glossopteris, Brgt., in all the three sub-divisions of the 
Damudas, besides the occurrence of triassic species (of the age of the Gres bigarre) 
in both the Upper and Lower Damudas, proves that all three sub-divisions belong 
to the same age. 
c. —The species Gangamopteris cyclopteroides, Fstm., which occurs in the Lower 
Damudas (Barakars of the Kurhurban coal-field), and which is the prevailing fossil 
again in tbe Talchirs, brings tbe latter into relation with tbe former, as I shall show 
presently. 
d. —There is no difficulty in determining the age of the Damudas. We have to 
regard only the most important fossils, viz.: — 
ScJiizoneura Gondwanensis, Fstm. (a triassic form) ; 
Sagenopteris (gcaulis ?) Mesozoic. 
NeuropterU valida, Fstm. (a triassic form) ; 
Act inop teris Bengalensis, Fstm., Mesozoic. 
Voltzia acutifolia, Brgt. (Gres bigarre); 
and perhaps Alhertia speciosa, Scliimp. (Gres bigarre). 
All these are closely allied, and some are identical with species which hitherto are 
known onlylrom lower triassic; no form is palaeozoic, except Sphcnophyllum, Brgt., 
which,however, shows very different characters from thoseof species from palasozoic rocks, 
therefore, considering all that 1 have said and determined, we are obliged, following the 
generally adopted palaeontological laws, to consider our Damuda formation as of lower 
triassic age. Considering the relations of the Damuda beds and the coal-strata in 
Australia, only the upper portion of the latter present some analogy with these Damuda
