and frequently cut up by dykes and large irregular intrusions of trap, 

 but, despite their much older appearance'^ and greater thickness, they 

 appear all to be attributable to the Bagh group. Similar sandstones are 

 associated with those beds west of Chota Oodipoor. The uppermost beds 

 near the Deva, too, are calcareous shales, similar to those which occur 

 north of the Nerbudda, and containing the same fossils.

 steadily under the traps ; the north and south boundaries are faults, and 

 the east boundary may also be a fault, but it has 

 rather the appearance of an abruptly denuded 

 termination, as if the lower traps had been consolidated against a pre- 

 existing sandstone cliff.

At the junction with the trap close to Doomkhul,

these beds roll somewhat with a general rather low north-west dip, and
