No fossils, except a few indistinct fragmentary plant remains, were 

 found here. 



The lie of the beds is rather flatter than at Ragavapuram, but there 

 is at times a good deal of undulation, which, however, is in part due to 

 slipping of the strata on the slopes. 



Here there is little correspondence with the Bagavapuram section, 

 except in the thick band of shales, now much lessened, and in the stronger 

 development of the ironstone band. The beds below the shales are 

 very variable, and they are not constant for any distance, showing that 

 they are, in fact, bottom beds of a series. 



There is no large exposure of the mode of superposition of this shale 



Eelation to Gollapili series on the Gollapili beds. Where the junction 



S* ^' is seen, they are always lying on hard ferru-
