CHAP.9.]  KADAPAH FORMATION.—PAUPUGNEE BEDS : SERPENTINE, 167 
Over the whole of the belt of these limestones sind slates south of 
Denudation of Vaim- MS Ryalcheroo and Gooty road, the strata are 
pullys. denuded into a set of parallel valleys between low 
rounded hills, which hills are quite characteristic in the marked way in 
which they are contoured by lines of outcropping strata showing along 
and round their flanks. The beds are dipping at so low an angle—as 
a general rule, from Boss MI they often crop out all round a 
hill or series of hills, giving the country a most picturesque look, with its 
ringed and sinuously parallel-lined ridges. This peculiar feature is 
seen at intervals very well displayed, more particularly in the epey 
area, and again to the north of the Penn-air.

There is no such characteristic form of denudation among any of 
the limestone series 1n any other part of the area. 
The greatest thickness of the Vaimpullys isover 3,000 feet, while 
that of the Goolcheroos is over 900 feet; but 
Thickness of group. 
they are never seen both. together equal to the 
sum of these estimates.
