of the Ckittrawutty river as it enters the Kadapak District. Here, they are quite distinct 
from the adjacent granitoid gneiss and the superincumbent Yindhyan quartzites. Again, 
on the western edge of the Nellore District, south of the Pennair, there is an extensive 
belt of similar rocks which I have doubtfully mapped for the present among the Vindhyans 
of that part of the country. 
Close to Ycllambile, however, the series is rendered extremely interesting from its in-

A short distance (some 500 yards or so) north of the village, there are several beds of 
limestone cropping up in the jungle, on either side of the path to Munderkheil. They 
are striking about east by north, west by south, and aro either vertical or dipping at high 
angles north, or south; while they arc traceable to the northward for some short distance, 
and southwards as far as Gutmulla. Bulges and bands of highly altered and crushed quart¬ 
zites run between the bands of limestone strata. 
Again, some 8 or 9 miles north-west, at the villages of Bungarchilka and Ivoyergoodium, 
there is a further exhibition of limestone beds of the same

plainly. 
Generally, the beds are of pale (weathering darker) grey and white laminated sub¬ 
crystalline (not saccbariue or granular) limestone; the 
lamina; running easy or parallel with the strike. This, for 
instance, is the style of the beds nearest to Yellambile; but almost immediately north there are 
other beds forming a broad belt traceable south-west almost to the Bannersammi Vagu, which 
are not simply laminated but have their layers of different matter arranged in waving and 
undulating lines, rapid contortions, lenticular masses with enveloping laminae, and knots of 
all forms. The undulations are equally various on surfaces across, or with the strike. 
The harder lamime, still soft enough however to be scrached with a knife, stand out 
well on weathered surfaces; and they appear to consist of some form of Pyroxene, and are 
generally of a grey or greyish-green color, and again at times quite white. Somo of the 
laminae are occasionally of a more decided green color, and they then are possibly serpentin• 
oas, but this is rare. They are equally unaffected by acid on fresh or exposed surfaces. 
The outstanding layers are also themselves finely laminated; and as they widen out 
often to half an inch or more, they assume a granular form, and are occasionally fringed on 
one edge. A number of such layers often run together and thus make up a broad seam of 
irregular laminar-granular structure. 
Though not a particularly bright-colored rock, it still shows these characters on half 
polished surfaces (I could only grind them down so far in camp), and they are then if 
anything more 'Eozoon-like. 
Much of this limestone is more or less micaceous, and is then somewhat schistose; but
