32 KTNG : COASTAL REGION OP THE GODAVARI DISTRICT. 



Nevertheless, there are undoubted hard and vitreous bands and beds 

 which owe their induration and jaspery condition to other than mere 

 weathering forces, which are properly characteristic of the group. 



Such is the style and condition of the first 40 feet of the group in 

 the greater part of the length of the outcrop, that is, between Davanawar- 

 gudem and Yadavol. Beyond the latter place the beds are generally 

 softer and freer ferruginous sandstones, still of the usual dark-brown and 

 reddish colours. To the south-west of Davanawargudem there is quite 

 a change in the character of the beds, which will be referred to imme- 

 diately. 



Above the scarp beds is a set of somewhat softer and more variegated 

 freer sandstones which are only known by the few wells between 

 Unnamalanka and Yernagudem. 



A few poor and unrecognisable vegetable remains, such as fossil 

 wood, probably coniferous, were all that could be found ; and these are 

 always in the softer beds between Yadavol and Annadavarupad. 



To the south-west of Davanawargudem, the hard ferruginous or 



Variations in members scar P beds tnin out under tne low scar P to the 

 of group. south of Tundkalpudi, and are very little separated 



from the heavy ferruginous beds of the Gollapilis, which are here locally 

 the ' Gut ' beds of Sanashi and Kunlacheru ; and they are more or less 

 recognisable as far as the left bank of the Tammileru. The upper 

 softer variegated beds are replaced by a set of strata in the scarp 

 which are quite different to the usual style of beds in the three groups, 

 with the exception of some of the Kunlacheru beds, the resem- 

 blance to which is such that W. T. Blanford 1 was very naturally in 

 the preliminary survey led to suppose that they belonged to the Kamthi 

 series. 



These new beds begin to show in the jungle to the west of Davana- 

 wargudem, south of Tripati. Yellowish-brown laminated felspathic 

 sandstone, the sand fine or not easily distinguishable, more properly 

 a fine clayey sandstone with frequent seams of white clayey fragments
