NtfRBUDDA DISTRICT. 207 



within the larger area examined by us there is not the slightest shadow of 

 evidence to bear out this supposition of the subsequent intrusion of the 

 lower trap. In many cases the bed of the intertrappean sedimentary 

 rock shows every gradation from a hard porcelanic flinty mass to soft 

 clay, and in every case this gradation is distinctly from the hard mass in 

 contact with the lower surface of the upper flow, to the soft and unalter- 

 ed deposit in contact with the surface of the lower trap. It is obvious 

 that precisely the opposite of this would be the fact, if Mr. Hislop's 



Goraha a small village situated in the flat country beneath the Northern scarp of the Omur 

 Kantak table land. The drainage of this plain falls into the Sone. The village of Goraha 

 is itself placed on sandstone Cof " lower Damuda" age) over which are strewed numerous 

 blocks of altered intertrappean strata, derived from the beds in situ on the hills adjoining. 



Near Mundla, further to the west, at a village called Pulsagur, the intertrappean beds are 

 seen in situ : and here are interesting from the gradation which they exhibit in the 

 amount of alteration they have undergone. The upper portion is converted into a black 

 cherty mass, from which it is exceedingly difficult to extract specimens, although shells 

 (principally Physa Prinsepii) are by no means rare: while the lower portion of the bed is 

 softer, of a brownish colour, and in parts earthy. In this portion the shells (chiefly Lymncea 

 and Paludina Deccanensis) are well preserved, and easily procured. 



The rich localities in the Nagpur territory, are next, in position, as we proceed westward. 

 AH our specimens from these have been contributed by Kev. S. Hislop. These are Chikni, 

 Taki, Telankheri, Phisdara, Karuni, Butara, and, further to the west, Ellichpur. These 

 localities, or at least some of them, have also yielded numerous vegetable remains, which 

 are of great interest; and which it is hoped, Mr. Hislop will succeed in having carefully 

 examined and described. 



Similar fossils occur at Gujri at the base of the Gharee ghat in the valley of the Nerbud- 

 da, and in a few places near Buowai (chiefly, if not entirely Physa). 



A very important fact, if supported by further and more careful investigation, has been 

 stated with regard to these deposits by Messrs. Schlagintweit, and repeated by Mr, Hislop. 

 This is the occurrence in the same beds of " the unmistakeable freshwater Physa 

 Prinsepii, with numerous true marine species " (a) near to Rajahmundry, on the God- 

 avery. Mr. Hislop, who, however, ha's not had the opportunity of visiting the locality, bears 

 out this statement. (b)
