Supplemental Note on the Plant-bearing Sandstones of Central 

 India *. By the Rev. Stephen Hislop. 



(In a Letter to the Assistant-Secretary, dated Nagpur, July 19, 1861). 



[Read at the Evening-meeting, January 8, 1862 ; and, by Permission of the 

 Coimcil, printed in the February Number of the Journal.] 



** Recently I have obtained more Insect-remains t from Kota, with 

 a morsel of Sphenopteris in the limestone; also smlchthyoUte, probably 

 JEchmodus Egertoni. 



^' I think there are strong reasons for believing that the ichthyo- 

 litic beds of Kota are superior to our plant- sandstone and coal J; and 

 hence, if the former be Lower Jurassic, the latter must be older. 



" In the sandstone at Sironcha, six miles further down the River 

 Pranhita, there is an abundance of compressed stems identical with 

 those at SilewacZa ; so that there can be no doubt that the argil- 

 laceous sandstone there is of the * Damuda group.' This sandstone 

 of Sii'oncha is stated by Mr. WaU to underlie almost immediately the 

 Kota limestone." 



After remarking that the genus Tceniopteris occurs both in the 

 Rajmahal Beds of Bengal and in the " Damuda Beds " of Nagpur, 

 Mr. Hislop proceeds to state that the largest Tceniopteris from 

 Kampti (near Nagpur) is exceedingly like T. lata and T. multinervis 

 of the Rajmahal Beds. The Tceniopterides, thus closely approaching 

 in form, prove, in his opinion, that the Damuda and the Rajmahal 

 Beds cannot be widely separated.

t The associated Est her ia {loc. cit. p. 356) has been carefully examined, and 

 appears to be different from that found at Mangali : both are new species ; the 

 latter, however, is very similar to an Estheria found living in Palestine. — T. R. J.
