nor are they very coarse; the pebble beds and grits with layers 
of clay-gall cavities being more frequent. Some of the beds, 
more particularly the lower ones, are very ferruginous, as may be well 
seen in the quartzite cappings of the flat-topped hills of the Koilkoontla 
taluq, where the beds are quite unaltered-looking laminated ferruginous 
grits and sandstones, full of clay-galls in layers, and obliquely laminated. 
The thicker beds here are much weathered into little pits and hollows, 
and are full of spherical concretions of brown peroxide of iron about 
the size of a walnut. 
It is from these peculiar flat-topped or plateau hills of the Koil- 
koontla taluq that the name appended to this member of the Paneum 
group has been adopted. Most of the hills detached from the main 
Oopalpád plateau are, in profile, like exceedingly squat truncated cones 
with flat tops; the capping being of these quartzites. The following 
sketch will give an idea of these hills :—
