146 KING: KADAPAH AND KARNUL FORMATIONS.  . [PART III. 
Chey-air and its tributary, the Chitt-air, his observations showed that 
other and lower bands of slates and sands were very gradually tailing in 
from the north. 
T subsequently followed out the western scarp rocks and the depo- 
‘near beds gf. SIU above them, finding, likewise, from Kurnool‏ مان 
northern half. southwards, that the lowest beds are sands and‏ 
conglomerates, with, however, a not very decided band of slates; over‏ 
these comes a very continuous and well-marked series of slates with‏ 
limestones, to some extent rather like the slate series which Mr. Oldham‏ 
traced above the southern quartzites, or, as he used to denominate them,‏ . 
the * Naggery quartzites.’‏ 
But, to the south of Cuddapah, this so well-marked series of 
Near Goolcheroo, south /mestone-slates of the Paupugnee river valley 
prec Op disappears quite suddenly, partly by faulting, 
partly by being covered up by a superincumbent unconformable series of 
quartzites, and by thimning out. At any rate, they thin out along 
the base of the northern slopes of the Goolcheroo hills; and they 
cannot, on any view of faulting or undulation of strata, as far as is 
at present known, be supposed to be represented by the limestone-slate 
band further eastward under the Polleonda hill,* which is continuous 
into the slate series of the Chey-air valley. 
Indeed, Mr. Oldham shows by his notes that there are represent- 
atives along the hills north of the Chitt-air, of slate and quartzite bands 
which I have seen on the western slopes of Polleonda and im the flat 
Bogroo (Booggoo) valley south of Cuddapah, which are not associated 
with the quartzites of the Goolcheroo hills. 
So far there is good reason to suppose that the Goolcheroo quart- 
Gdoleheroo MET zites and the slates above them are not represent- 
Joest beds: ative of the Naggery quartzites to the south 
and their superincumbent slates, but that the Naggery quartzites 
* South-east of Cuddapah town.
