occurrence in great abundance of certain foiuns, such as Voltzia and Newropteris, 
which had never been noticed in true Damuda rocks, made me suspect that there 
must be some distinction in the beds, and this view was strengthened by further 
examination of the flora. In July last Mr. Hughes and I paid a short visit to 
Karharbari, and by the assistance of Mr. Whitty, Superintendent of the East 
Indian Railway Co.’s collieiies, we were enabled to see much of the ground in a 
short time. Wo came to the conclusion that there was an important distinction 
between the Karharbari coal and that of the Damuda series (both Barakar and 
Raniganj), the laminated structure so peculiarly chai’acteristic of Damuda coal 
being almost absent in the Karhai'bari seams, and, moreover, the conglomeratic 
beds associated with the Karhai’bari strata contained subangular fragments, 
whereas the Barakar pebble beds contain usually none but well-rounded jjebbles. 
The topmost beds in the little field had rather the aspect of Barakars, and some 
indications appeared to suggest that these beds overlapped the Karharbari group 
nnconformably, but this was not by any means clearly determined. Still, con¬ 
sidering the great similarity between all the coal-bearing beds, the distinctions 
noticed all tended to bear out the separation of the group first suggested by the 
fossils. 
The following is a list of the fossil plants determined by Dr. Feistmantel: — 
Eqtjisetacbj:— 
Yertehraria Indica, very rare. 
ScMzoneura sp., near Equisetum Meriani. 
Filices— 
Neuropteris valida. 
Gangamopteris cgelopteroides. 
G. angitstifolia, nntl two other species of Oangamopteris. 
Olossopteris decipiens. 
G. communis. 
Saqenopteris StoUczJeana. 
CvCADEACEiE— 
Glossozamites ^toUezhana. 
Noeggerathia {Zamia ?) Hislopi, var. 
W. Iz. ?), sp. 
A peculiar genus, unnamed. 
CoNIFERjE— 
Voltzia heteropliylla. 
Alhertia, sp. 
If this flora be compared with that of the Damuda scries quoted at page 134, a 
very marked difEerence will be noted, a difference nearly, if not quite, as marked 
as that which divides the Damudas from the Panchets, and which is considered 
by Dr. Feistmantel to justify the classification of the former as Bunter, and of 
the latter as Keuper. Out of four fairly recognized plants in the Panchet beds, 
one is a Damuda form, but it is the commonest and best preserved of the Panchet 
species. Of the sixteen species above mentioned only three arc known to be 
found also in the Damudas, viz., Olossopteris cornmnnis, Vortehraria Indica and
