CHAP. 1.] THE KADAPAH FORMATION. 147 
are those which are overlying the Paupugnee limestones south-west of 
Cuddapah. 
There are, however, some features against this: the Paupugnee band 
Dx against this Of Slates is overlaid quite unconformably by 
VIS this band, the lowest beds being of conglomerate 
and breccia, made up of the debris of the subjacent strata; but these 
cease to the south of Cuddapah, and there is no unconformity visible 
in the hilly country further southwards, traversed by the Chitt-air and 
Chey-air. The basal conglomerates and breccias of Goolcheroo may 
certainly have died out to the east, while the thick upper sandstones 
and grits of the same band were eventually spread out beyond the 
Goolcheroo beds on to the cRYSTALLINES, and are thus the bottom beds 
for the southern portion of the western scarps. 
Again, the strata seen south of Cuddapah between the conglome- 
rates of the low hills south-west of Chintakonadinna and Pollconda, 
are very far from resembling the strata above the quartzites on the 
left bank of the Paupugnee, except in the presence of limestone bands. 
Still, these changes of characters in strata are not Impossible; and 
it is very probable that only a small portion of the slate group under 
Polleonda is there visible; for the quartzites capping this hill are 
unconformable on the subjacent beds. - 
There is, besides, a great deal more of the strata above or north of 
the quartzites on the left bank of the Paupugnee obscured by superficial 
deposits, than of the strata of the Chey-air valley, and this alone, with- 
out taking into account the presence of voleanie deposits in the former 
area, would hinder any recognition of general resemblance between 
the two. 
It is to be confessed that, on the face of the map, and even from the 
appearance of the rocks and of the country, the long outcrop of lowest 
beds from Tripetty to Kurnool is very like that of one series ; but it is 
impossible to get over the fact of the Paupugnee limestones dying out
