94 KING: KADAPAH AND KARNÜL FORMATIONS. [PART II. 
Attention has been already drawn to* the occurrence of some flat- 
D E. cease topped hills in the western part of the Kuddapah 
Paupugnee and Chittra- district between the Paupugnee and Chittravutty 
dins rivers, which are capped with quartzites and which 
from the resemblance in shape and the fact of their sides being occasion- 
ally strewn with great blocks of quartzite might be taken to be of the 
same structure and constitution as the flat-topped hills below the Oopal- 
pád plateau. "These caps of quartzite are perfect outliers of one or other 
of the different groups already described; but it is utterly impossible, 
without a much closer examination than we could make, to say of which 
one. 
They lie unconformably on traps and shales which are known to be- 
long to the KADpAPAH formation; and the only other quartzites from 
which they can certainly be distinguished are those of the pinnacled 
beds. "They are very like the southern outerop of Banaganpilly beds, 
and seem naturally to be outliers of it, for both are only lying on Kapa- 
PAH rocks; but there is no record of diamonds having been found in 
them. For the present, it is taken for granted that they do belong to this 
group, though it is not impossible that they may be plateau heds of 
the Paneum group, or even the intercalated quartzitest of the Nerjee 
limestones so well and distinctly developed on the Oorchintala terrace. 
These doubtful and isolated quartzites certainly resemble the plateau 
beds very much, but if they be really so, we should have to account for 
the total thinning out and disappearance of the Owk shales, Nerjee lime- 
stones, and Baxaganpillys, of which there certainly do not seem to be 
very evident signs along their present southern edge, though they are 
thinning out. Again, the intercalated quartzites of the Nerjee lime- 
stones are thickening along their southern edge in the Oorchintala ter- 
race, while the belt of limestone below them has thinned out, and dies
