IDENTIFICATION AND RELATIONS OP THE ROCK GROUPS. 95 



Nagptfr. They are distinct in lithological characters from the ironstone 

 shales and Raniganj divisions of the Dainuda series in the east, but 

 the fossil plant-remains which have been discovered in them and deter- 

 mined by Dr. Feistmantel shew them to be the representative in time 

 of these groups. 



The single Labyrinthodont reptile from Mangli affords no certain 

 clue to the correlation of the beds in which it occurs. 



I am not aware, and I think it was impossible to tell, owing to the 

 imperfections of the sections, at what horizon in the Kamthi series 

 the plant-remains procured near and around the station of Kamthi were 

 obtained. In the Wardha valley, the specimens by which the affinity of 

 the Kamthi and Raniganj groups was pointed out were derived from 

 the lower beds of the Kamthis. None were found in the higher strata. 

 There is thus left an upper horizon, which being as yet barren of evidence 

 connecting it with the Raniganj epoch, may be assumed as the represen- 

 tative in part or in whole of the Panchet period. 



I think it probable that this assumption may turn out to be a correct 

 one, unless it be eventually shewn that the Kota-Maleri beds are the 

 equivalents of the Panchets. 



Kota-Maleri group. — As far as the evidence at present accumulated 

 may be depended upon, the Kota-Maleri group is younger than the 

 Panchet series of Bengal, the plants that it contains being of Jabalpur 

 and Rajmehal age, and the fauna exhibiting weaker European triassie 

 affinities than that of the Panche't series. 



In this field the Kota-Maleri beds are the highest representatives of 

 the Gondwana series, and they are provisionally placed between the Raj- 

 mehal and Panchet groups, as the oldest members of the Upper Gond- 

 wanas (see table, page 9). 



Dr. Feistmantel, in a paper contained in the last issue of the Records 

 of the Survey, has endeavoured to shew that judging by the flora of
