stratigraphical and palaeontological breaks. It is with the 

 lower divisions that we are at present concerned ; this in- 

 cludes three series, at the base the Talchir and Karharbari 

 beds, followed by the Damuda and Panchet series.

"Ranigunj and Kamthi. 

 Barakar. 

 "Karharbari. 

 _Talchir. 



The Talchir and Karharbari beds consist of shales, 

 sandstones, conglomerates and coal seams. Towards the 

 base of the series boulder beds occur over a wide area, 

 made up of fine silt full of rounded and subangular striated 

 rocks, varying in size from ^ inch to 15 feet in diameter. 

 In some places the boulder beds rest on a platform of 

 older rocks exhibiting the polished and striated appearance 

 of an iceworn surface.
