found so very clearly in some localities as one set of beds without inter- 
calated slates, while in others they show as numerous bands among 
slates. Or there may be two sets of beds, one low down in the Cumbums 
and the other near the top of the series. In the Kullsapad belt, the 
beds are generally of grey colors, fine-grained, semi-crystalline, and 
waxy-looking. 
The limestones of the Penn-air are generally of a more compact and 
Limestones ofthe Penn. ‘Wicious character than those in the Cumbum 
ae country, though they seem to belong to the same 
series.* There are likewise two bands of limestone here, which come 
out more distinetly in the Lunkamulla range north of the Penn-air, on 
the western flanks of this mountain mass, the lowest running along the 
base or near the base, while the second crops out about halfway up 
the slope. 
There is a fine show of the lower band of limestones in the Bauk- 
rapettconda to the east of Cuddapah town; but

their lie, and that of the quartzites and slates 
both above and below them, is exceedingly obscure, owing to the crushed 
up arrangement of the strata between Baukrapett Peak and Polleonda 
on the western side of the marrow valley leading south-west from 
Cuddapah. 
* For the present, this doubtful area is considered as belonging to the Cumbums و‎ 
though I feel in my own mind that it is a mistaken view of the relations of these strata. 
I am strongly inclined to look on these beds of the Baukrapett hill and even of the whole of 
the Lunkamullas as not of the Cumbums at all, but as Poolumpetts, and that they are 
let in here by a series of faults, of which the Kaukulconda fault down on the Penn-air, the 
evident dislocation in the Baukrapett pass east-south-east of Cuddapah, and the fault along 
the Nundiallumpett beds of the Nullamullays are parts. Certainly the Baukrapett lime- 
stones are intensely like the Poolumpett beds; while the Lunkamulla strata are not at all 
like the strata north of the line of faults striking east and west through Nundiallumpett. 
At the same time I do not consider the strata of Ontimitta and to the south of that 
village as anything else but Cumbums. 
I confess, however, that I am at a loss to show this at all clearly on the map; and in 
fact it could not be done except after a thorough and close re-examination of the Lunkamulla 
region. —W. K.
