seen, are in the long fault lines west of this. These beds, which are lying 
easily close by, are laminated with the white oolitoid chert of the 
Vaimpullys. * 
Now, the conglomerates, &c., just described, are evidently the same 
O e el beds which strike round here from the ridges on the 
CRUS e cs Ded western bank of the Paupugnee, but their continuity 
with the quartzites on the eastern side of the Bankrapett stream is hidden 
by alluvium and possibly broken by some faulting. In the hill plateau 
south-east of Bankrapett there 1s, however, the same series of quartzites 
again overlying red shales and limestones which eventually thin out 
and disappear.

Taking a section aeross the valley south of Cuddapah, the conglo- 
Section south of Cuq- Merate and grits of Chintakonadinna hill are 
CAPAS overlaid by thin sands and sandy shales and more 
quartzite, which are the rocks close up to the Bankrapett stream. Then 
there is nothing seen but alluvial deposits until the Boogoo stream is 
* The oddly picturesque masses of quartzite strata capping the plateau hills beyond 
(south of ) Cummawarpully are, I think, of the newer KARNULS; they overlie, at any rate, 
the quartzites referred to above, further westward.—-W. K.
