e. Barakur group, with which the 



d. Talchir group — is in closest relation. 



Thus stands now our knowledge of the relations and conditions of the 

 Damudas, in which of course our Raniganj coal-field is included. 



The flora — the only remainder of former life— of that Damuda series 

 will be worked out as a whole later on. But in the meantime some 

 shorter papers may illustrate certain groups of fossils which are contained 

 in collections other than those of the Geological Museum. 



Of such papers the present is the first, and the fossils were collected 

 by Mr. Wood- Mason. 



First of all I will give a list of the fossils found by Mr. Wood-Mason, 

 then the descriptions, amongst which I also include short notices of 

 such fossils as occurred in the Raniganj field, but were not found again by 

 Mr. Wood-Mason.
