shale, and there is little doubt that they come from a similar bed of shales to that 
mentioned before as above the sandy micaceous greenish-yellowish shales with 
fossils. They comprise— 
Schizoneura gondwanensis, Fstin. The same form as in the Eauigauj, Jherria, and Hingir 
coal-fleld. 
Olossopteris communis, Fstm. The same form as in other places. 
Besides these there is a single specimen labelled “ Denwa naddi, Pachmari.” 
It contains— 
Trizggia speciosa, Eoyle {Sphenophyllum trizggia, Ung.), which chiefly occurs in the Rani- 
ganj coal-fleld (Haniganj group), in the Talchir coal-field (Barakar group), and is doubtfully quoted 
from the Damuda rocks at Pankabari. 
There is no doubt th,at this specimen also comes from this fossiliferous zone 
of shales in the Bijori horizon in the Upper Denwa valley. 
If we now consider the fossils mentioned above as coming from the Bijori 
horizon in the Denwa valley, i. e., Schizoneura gondwa- 
seJt^tS^ldmlrEanTg^ani ’ ^rizygia spemosa, Eoyle, Vertehrariaindica, 
group. Royle, Olossopteris in various foi’ms, Peeopteris angusta, 
H., etc., w'e find that all these occur also in the Rmi- 
ganj group in Bengal, so that the fossiliferous band is correctly considered 
as representative of this group in the Satpura coal basin, in which case those 
sandy micaceous unfossiliferous shales immediately below the Pachmari sandstone, 
and the beds of the same position near Almod and Rorighat (which have been 
distingui.shed as Almod beds), would perhaps represent the Panchet group of 
Bengal, this the more if we consider the close relation of this group in Bengal 
with the Raniganj group, and the much smaller number of fossils in the former 
than in the latter. 
. I made also a search from Barikondam to the west, at and round the spot 
Archegosaurns in the where the said Archegosaurus was picked up by Major 
Bijori horizon. Gowan but no trace of any fossil was found in the 
Bijori sandstone. 
Fine earthy sandy-micaceous gi’eenish-yellowish shales were observed, as 
Shales at Almod and Ro- already mentioned, near Almod and Rorighat; except 
righat. indistinct marks, they were found otherwise unfossili¬ 
ferous, and they appear to be the same as those mentioned before as imme¬ 
diately underlying the Pachmari sandstone. 
Further to the west, however, on the road from Rorighat to Shapur (by 
Plants between Rorighat Harapala, Jhuli, &c.), about five miles from this place, 
and Harapala. j found in a nalla some shales containing plant remains.
