Out of all these, only one, Cardita variabilis, is common to the inter 

 and infra-trappeans. The latter are clearly marine, in contradistinction 

 to the Pungadi and Kateru beds which are estuarine. 



Infra-trappeans. — The lowest beds associated with the traps occur at 

 the base of the northern slope and along the western half of the Pungadi 

 range of hills, 12 miles to the west of the right bank of the Godavari, 

 where by their position they succeed the Tripati sandstones of Yerna- 

 gridem. They consist of a series of sandstones, calcareous towards the 

 top, with an upper seam or crust of fossiliferous limestone. These strata 

 are more or less exposed at three points along their outcrop, namely, 

 a little south of Gowripatnam, at their eastern end; again on the 

 road from Pungadi to Dudkrir, about a mile before reaching the latter 

 village ; at Dudkur itself, and a little south of it ; and again at a point 

 near Devarapili, at the western end of the outcrop. From end to end 

 the exposures indicate a length of about three and three-quarter miles. 



The greatest thickness ascertainable occurs at Dudkur, where there 



are 48 feet of sandstones, &c, and the lowest 



beds are not exposed, a good width of ground 



between these and the Yernagiidem sandstones of the Tripati group 



being made up of superficial deposits.
