^.—Bara&ars, are much faulted, and, as the nullah is extremely sandy, 

 it is scarcely possible to make out the sequence. At first the 

 beds are much obscured by sand for about 500 yards, followed 

 by beds which I identified with beds of the Sendur sections 

 as follows : — 



4. Purplish-red and grey shales, about 14'. 



2&3. Grey carbonaceous sandstone, locally faulted and 



crushed. 

 1. Red and grey shales, 14', with the following fossils : — 

 Vertebraria indica, Eoyle. 

 Olossopteris communis, Fstm. 



„ browniana (indica 1). 



„ damudica, Fstm. 



k,-^TalcMrs, are represented in this section in great thickness, and are 

 typical in lithological character. Great masses of the boulder 

 bed, with associated marly shales showing the jointing as usua , 

 of greenish-grey colour, occasionally reddish-brown and 

 mottled. The strike is north-west to south-east, with a dip to 

 the south-west of from 25 to 30°. With it occur large masses 

 of fine mealy yellowish sandstones, with layers and bands of 

 boulders, rapidly swelling or thinning out, being then often 

 replaced by boulder ^beds. The sandstones are worn into
