southern part of the field, where indeed the most interesting denudation 
of the KaRNUL rocks seems to have gone on, and are just below the 
south-east corner of the Oopalpád plateau and its outlying flat-topped: 
hills in the neighbourhood of the villages of Noyanpally and Pellny- 
Limestone grite and O2: Close by these villages, the ‘blue beds? 
conglomerates, of the Nerjee limestones rest at once and uncon- 
formably on quartzites, and at the same time present the rather strange 
composition, for this particular band of limestones, of a calcareous grit, 
conglomerate, ard pebble bed. At Noyanpally, just west of the village 2 
are thick beds of the typical blue limestone in the stream-bank, 
weathering into coralloid forms. The bottom bed of these is a very coarse 
white calcareous sandstone, apparently enclosing fragments of the com- 
pacter limestone. This is, however, deceptive, the bed being irregularly 
seamed with white sand, which has assumed occasionally a-rather tortuous 
and broken course in its deposition throughout the rock. These lower 
beds of limestone and calcareous grit lie unconformably up against an 
undulating set of quartzites. 
To the west of Pellnycota, the Nerjee limestones are seen 
to be distinctly unconformable to these quartzites. They are lying 
horizontally over undulating beds, and in many places may be seen 
lapping round protruding knobs of quartzite with irregular bedding. 
The lowest beds of limestone are full of layers of small pebbles thickly 
gathered together; and these occasionally become a very coarse con- 
glomerate of large, smooth, and round pebbles of quartzite with occa- 
sional large pebbles of trap. There is also a thin bottom bed (in another 
part of the boundary west of the village) of nothing else but small 
pebbly gravel in a matrix of limestone. At two or three points west- 
south-west of the village and close to the boundary between the 
limestones and quartzites, there are calcareous conglomerates of the 
most coarse character which are quite wonderful in the size and 
smoothness of the enclosed boulders of quartzite and occasionally of
