was made out. They resemble the typical Lameta limestones in the 

 Jabalpur district. Of the less common varieties of limestones, One 

 exhibits a cone-in-cone structure; another, a honeycomb arrangement; 

 and some of them are built up on a curious kind of net-work plan, 

 through which strings of different-colored limestone pass. Thin, earthy, 

 calcareous beds, and arragonites also occur. 



At various times the Lametas have yielded very abundant collections 

 of fossils, and one of the most noted localities is

that of Pisdiira. This was one of the spots dis- 

 covered by Hislop, and in his paper " On the Tertiary Deposits asso- 

 ciated with Trap Hock in the East Indies"* he enumerates "bones of large 

 Pachyderms, Cqprolites of various sizes; Saurian teeth; vertebra of a 

 large fish; and fragments of the plastron of a fresh-water turtle;'" and 

 inter-trappean shells. " Paludina normalis ; Paludina Wapsharei, Lim- 

 nosa oviformis and Physa Prinsepii var inflata." 



In the Quarterly Journal for 1864, f further mention is made of the 

 discovery of bones. " One femur upwards of a foot broad at the con- 

 dyles," and one vertebra about 7 inches across. 



Following in Hislop's footsteps, I succeeded in also procuring some 

 bones ; coprolites, and the shells mentioned by him. The bones comprise 

 portions of limbs, and vertebrae. They were all much broken and 

 looked rolled. Of the vertebrse only the centra occur. Of the long 

 bones, the ends with the processes worn off. The coprolites do not 

 appear to have been subjected to any violent motion. 



The locality for these fossils is a field at the southern extremity of 

 Pisdura hill, and they occur on the surface, having been turned up by 

 the ploughing of the land. The most conspicuous beds are red clays, 

 but the ordinary-type sandstones may be seen in a small shallow stream 

 a few yards south of the road leading to Khemji.
