50 CRETACEOUS TICCK.S OF S. iXlilA. [PaRT II. § 1. 



been noticed on the map, and having simply determined the existence of 

 these plant remains, without delaying to investigate more carefully their re- 

 lations, I communicated the facts to Mr. Blanford, leaving it to him to work 

 out the relations of these beds, when he came to finish this portion of the map. 



The results arrived at during my personal examination of these plant- 

 bearing beds, I briefly stated in a short notice in the 2nd volume of these 

 Memoirs (page 320). In this paper I took as the true age of the Ootatoor 

 beds what was then supposed to be so, and assumed them to be Neocomian. 

 Since then Mr, Blanford has had fuller opportunities of working out the 

 fossils of these beds, and so far as the Cephalopoda are concerned (the 

 only group as yet examined in any detail), they seem to indicate that the 

 Ootatoor beds are not older than the middle portion of the Cretaceous 

 period. So far, of course, the reasoning as to the age of these plant-beds 

 must be modified, and, as very justly stated by Mr, Blanford, all that is 

 proved by their position in Trichinopoly is that they are not newer than 

 the lower portion of the Middle Cretaceous period. 



Mr. Blanford, however, as will have been seen, considered that these 

 beds at Maravattoor were conformably in sequence with beds containing 

 marine fossils of undoubted Ootatoor age, and were probabl}'- intercalated 

 with them, while the fact of his having found no trace of the remains of 

 plants during his careful and repeated examination of the beds, left a 

 doubt hanging over their true relations, which it was all important to 

 solve if possible. As soon, therefore, as I was aware of these results 

 arrived at by Mr. Blanford, I made arrangements to revisit the ground, 

 and to determine if any thing further could be made out. This I have 

 just accomplished and with the following result: — 



1. The plants first noticed by myself and Mr. Charles M. Old- 

 ham in 1859, do occur in several beds ; these plants are identical 

 with several found in the Rajmahal beds, and there are two which 

 appear to be identical with the only two recognizable species figured 

 as occurring in Cutch.
