prove the existence of a pair of bounding faults. 



This is further evidenced by the high inclinations of the beds, dipping 

 from the faults on both sides, which thus form a very decided synclinal 

 trough. I have already spoken of the obscurity of the relations near

right in relegating the anomalous beds to Talchirs, I think the rela- 

 tions represented must be correct, and that the Mahadevas rest here upon 

 Barakars, the Panchets and E-aniganjes having died out.

village. The thickness cannot be less here than 



about 700 feet. 



At the foot of the hills south-east of Panripura I found some red 

 shales of limited extension containing fossil plants. This was in im- 

 mediate proximity to the line of faulty and it was not possible to deter- 

 mine to which group they belonged. They arc 

 overlaid by whitish sandstones of somewhat doubt- 

 ful character, but higher on the slope are very similar red shales belong- 

 ing to the Mahadevas. The fossils include species of Glossopteris, 

 Vertehraria, Pecopteris and conifer seeds. It would be dangerous under 

 the circumstances, to refer them to any definite horizon. 



About three miles to the west of Latiahar there is a small hill formed

 ^^^* The beds here rest directly on Barakars. From an 



observation I made in the hot weather, when the jungle was bare and 

 the lines of stratification visible in profile from a long distance off, I am 

 inclined to believe that the beds have been faulted on the north, since it 

 was then apparent that the lower beds of the southern scarp were cut 

 out on the north.
