In the introduction to the account of the fossil flora of the Rajmehal 

 series in the Palseontologia Indica, the several 

 formations which occur in the Rajmehal hills are 



enumerated, and a general account of the character of the fossil-bearing 



beds is given. This latter is reproduced below. 



In a memorandum on the coal resources of India, Dr. Oldham gives

 refers to Rajmehal coal, will be found embodied in the tables appended to 

 the chapter on the economic resources.
