OF CENTRAL INDIA AND BENGAL. 335 



which are, I think, obviously of a totally different &ge.(a) The Umret 

 beds referred to by Mr. Hislop in a subsequent paper, (b) are " Damuda." 

 It is I think very doubtful if the Kota beds are of the same age. The 

 evidence derived from their abundant fish remains ; that from the occur- 

 rence, at Mangali, of the remains of Labyrinthodont reptiles, (Brachyops 

 laiiceps) and again of the abundant representatives of the genus Cera- 

 todus, at Maledi, convinces us that when the true physical relations, and 

 succession of these different groups have been made out, all these links, 

 now detached, and separate, will form one continuous chain, each finding 

 its own proper place in the system. And I think, great as the delay 

 may be, it is safer and wiser not to hazard any erroneous conclusions by 

 hasty speculation. 



Talcheer Beds. — From this lower group we have very few fossils. 

 These consist of a Phyllotheca (?) a large Cyclopteris like leaf and some 

 annelide markings. Data quite insufficient on which to base any conclu- 

 sion as to the age of the group. They seem, however, to indicate 

 that it is only a somewhat older sub-division of the great " Damuda" 

 series ; and this supposition is also borne out by the apparent passage of 

 one into the other in the Nerbudda, (and elsewhere). 



We shall reserve the discussion of the age of the Mahadeva series of 

 the " Intertrappean lacustrine" beds, and of the Miocene (? pleiocene) 

 ossiferous beds of the Nerbudda valley — for another opportunity.
