and Tundkalpudi scarps is that they have not as yet yielded any reeog- 

 Eepresented in the sizable fossils, while their abrupt finish at the 

 Vizagapatam country. river banks limits their identification with other 

 sandstones in the field. However, some 2-4 miles away to the north- 

 east of Rajahmundry, at Jaggampet, coarse ferruginous sandstones and 

 conglomerates are lying directly over a sloping floor of gneiss; and 

 beyond this, smaller and smaller patches of these occur near Kirlampudi, 

 Ayaparaz-Kotapili, Paidikonda, and to the east of the Srirampuram, one 

 of which has yielded fossils of Umia (Survey classification) or upper 

 Jurassic age. These sandstones are, in many respects, very like those 

 of either the Gollapili, Tripati, or even the Rajahmundry zones but 

 they are, on the whole, more like Tripati beds, and their upper Jurassic 

 age favours this correlation of them.

flat on the south side of the village. This is of gneiss overlaid by very 

 coarse ferruginous indurated clays and conglomerates, which are suc- 

 ceeded by a set of fine thick and thin-bedded grey and purple sands, with 

 a few clay-ironstone concretions, containing a few fossil shells. 



The beds are dipping about 8° — 10° south-south-west, and the ridge 

 may be about 40 feet high at the eastern end. 



The fossil bed is thin, a coarsish soft muddy sandstone of a purple 

 color, ferruginous, full of fragments of shells, which, from their ferru- 

 ginous constitution, break up very easily and fall to dust. It runs 

 along about half-way up the ridge between pale yellow and buff, and 

 pale purplish sands, soft and fine-grained, largely made up of concre- 

 tionary masses with hard purple sandy cores. Occasionally, fossils are 

 seen on a hard brown surface of some of the sandstone beds. 



The finer and more compact beds are overlaid by very coarse-grained 

 hard ferruginous sandstones of little rounded particles of clear semi- 

 translucent quartz, with occasional small pebbles of white quartz and 

 clay.
