The Athgarh sandstone (near Katak in Orissa) also represents the 

 Rajmahal group. 



On about the same horizon the following have most probably to be 

 placed : 



The " Pachmari sandstones,"* base of the Mahadeva in the Satpura 

 basin without fossils ; the " Dubrajpiir group"f of the Rajmahal hills, 

 which so far as is known with certainty, contains the genus Ptilophyllum 

 only ; the Sironcha sandstones,;*; near Anararn, on the Pranhita river, Central 

 Provinces, with fragmentary plant remains (conifers) ; and lastly, from its 

 geological position (below the Vemaveram shales), the Budavada group,§ 

 is probably also to be classed here although containing plants and marine 

 animals. 



Certain red shales on the Northern face of the Latiahar hill, in the 

 Aurunga coalfield, and containing Lower Gondawana fossils (Glossopteris, 

 Vertehraria &c.,) should most probably be included here also. 



a. Panchet Division. 



Panchet group. — 1861, Blanford (W. T.) Report on the Raniganj coalfield Mem. 

 G. S. I. Vol. Ill, p. 126. 



The uppermost group of the Lower Gondwanas is typically developed 

 in the Raniganj coalfield, from whence it was first described. It is here 

 fossiliferous, containing Labyrintlioclontia and Dicynodontia and plants. 

 It has its name from the Panchet hill, Bengal 



This group is also developed in several other basins but is scarcely 

 fossiliferous ; and the Almod beds (H. B. Medlicott) in the Satpura 

 basin are representatives of this group. 



h. Damuda Diyision. 



Banig an j group.— 1861, W. T. Blanford, M. G. S. I. Vol. III. 



Top-group of the Damuda series, highly fossiliferous and coal- 

 bearing. 



At first described from the Raniganj coalfield, where it is typically 

 developed. 



It was afterwards recognised in all the Damuda valle} r coal-basins, but 

 also beyond this region it is developed ; in the Aurunga coalfield, Kamkola 

 and Tatapani coalfields and quite typically also in the South Rewah basin.
