The Supahi and its tributaries south of the Doothoo hills afford

Talchirs, above which there are coarse Barakar grits dipping at 25", to 

 north-west. Above these there are somewhat conglomeratic grits, which 

 resemble certain beds occupying the same relative position in the 

 Aurunga field. The next rocks seen are rusty Iklahadeva sandstones 

 dipping 15°, to north. It is uncertain whether they are superposed or 

 are separated by a fault. 



In the Ledkee stream, which joins the Supahi near its entrance to

beds seen in the Atee at Bijka, and with them 



some others whose lithological affinities are certainly not with ordinary 



Barakars. Besides the green beds, there are grits which include 



angular fragments of gneiss, &c., and also firiecalcai^eous sandstones. 



Any attempt to separate these rocks as constituting a distinct 



Difficuty in separating group is beset with difficulties, since there are 



not a few sections in which the Mahadevas
