North of Allur (beyond the Penner), sub-fossils of the same species 

 are common, but not in such numbers as at Tada. 



There are also thin seams of indurated sand with recent shells occur- 

 ring" at intervals along the coast at the depth of a foot or so beneath the 

 surface, and fragments of such a deposit, apparently thrown up by the 

 waves, may often be seen along the sea-shore. I observed these more 

 particularly at Sriharikota, about a mile east of Raiaduru, where a shal- 

 low pool had been dug" in the sandy alluvium, and at the bottom of this 

 is a layer of indurated sand, with remains of Area, Cyrena, &c. Again, 

 on the shore here, at the fishing village, are fragments of a recent shelly 

 sandstone scattered about the beach. At this point the sea is cutting 

 into the bank, exposing a cliff of 4 or 5 feet in sandy alluvium, but 

 I could not find the outcrop of indurated sand. 



The alluvium of the rivers is very various. Those of the Penner 

 are pale sandy deposits, with more of the brown 

 and humic soils than occur in the deposits of the 

 streams to the south. Along the banks of this river there are only very 

 narrow strips of alluvium, with an occasional band up the tributary 

 streams. Out in the delta spread, there is generally pale-grey sandy allu- 

 vium, with good thicknesses of dark- brown and reddish-brown soils with 

 a mixture of lateritic sand and gravel. For the Kandleru, which flows out 

 to the sea at Kistnapatam, there is very little of the pale sandy deposits
