worked for, aud found, in quartzites of the Hyderabad territory which 
appear to be KADAPAHS. ۱ 
In 1867, Mr. H. B.. Medlicott made a run over certain rocks on 
the Mahanuddi, which he considers as Lower

rocks, while others are like the KADAPAHS. 
They consist of a set of limestones, slaty-shales, and quartzites, with 
porcellanic trappoid beds. 
The slaty-shales are very like rocks of the same kind among the 
Cumbums of the KADAPAH formation, which occur to the east of 
Mookundoo hill near Nundiallumpett, on the western flanks of the 
Nullamullays. The dark grey (weathering lighter), argillaceous 
limestone is remarkably like the flaggy limestones of the Koilkoontlas 
in the KARNUL ROCKS. 
The compact purple and greenish grey banded limestones may be 
either Nerjee limestone of the Jwmmulmudgoos (karnuL E), or 
Vaimpully limestone of the KADAPAHS; it is more like the rock of 
some of the Nerjee beds. 
For my own part I should certainly say that these rocks of the 
Mahanuddi are KARNUL and KADAPAH rocks; and they are by their 
lithology preferably of the KADAPAH formation. 
Again, Mr. W. T. Blanford has been working at rocks in the 
MAE EA. neighbourhood of Nagpur, about Chanda and 
puyans in the Nagpur the Pemgunga river. Looking at the specimens 
SERES of these rocks collected by him, their resemblance 
to beds of the KARNÜL and KADAPAH formations is very strong. 
Mr. Blanford considers them as Upper vixpHyaNs. They are shales, 
limestones, and quartzites. The shales are soft, red-purple, argillo- 
calcareous rocks. "They are, in fact, Nundial shales of the Khoond-airs. 
There is a specimen of argillaceous limestone from bands occurring in 
these < Pem shales,’ exactly like the same bands in our Nundials.
