KHIRTHAR RANGE. 81 



In this part of the hills there is a great resemblance between the 



Resemblance between Nari and Manehhar beds, and it is highly probable 



Nari and Manehhar beds. tnat hoth were deposited under similar conditions. 



The Nari rocks are harder than the Manehhar, but the sandstones in 



both are often of similar grey colour and structure. The shales in the 



Nari beds are usually darker than the Manehhar clays, but in the Kenji 



stream some nodular orange-brown shales are seen in the former, o£ 



precisely the same colour as the clays in the latter, and purplish-red 



clays, precisely like those of the Manehhar beds, are associated with the 



limestone bands near the base of the group. 



There is nothing worthy of notice in the two streams, Mogrio and 



Trappen, traversing the hills of Gaj and Nari beds

south of the Kenji Nai. On the Sita Nai (Toonee- 



waree of map), an excellent section of the Gaj beds is seen at the 



entrance to the gorge through the hills, the lower portion of the group 



being especially well exposed. The upper portion consists, as usual, of 



sandstone, limestone, and clay; the section towards the base is the 



following : descending —

1. Brown calcareous sandstone . . 



2. Hard brown limestone with Breynia carinata, EcMnolampas, 



Ccelopleurus, Schizaster, &c. This is a conspicuous hard bed, 

 always containing numerous echinoderms, and well developed 

 to the southward ......... 6

which are seen on the weathered surface .... 6
