K-lmtUi group near Cliiniir. 
complicated by faulting that I have overlooked, the Tarcherla sandstones are,- I 
think, more properly placed with the Kamthis than below them. 
Eocks that I consider to be Kamthis occur east of Chiniir, and overlie the 
Barakars at Sandi-apali. The porous type sand¬ 
stones are exceptionally well develojjed near Chin- 
talapur, wliere they form a low ridge striking north-west and south-east. The 
more compact varieties are best seen in the direction of Kotapali. The upper 
boundary as marked by me, near Sironeha, is open to question, for the reason 
already pointed out, that Mr. King is inclined to introduce a group between the 
Kamthis and the Kota-Maleris. To the introduction of this group I am some¬ 
what opposed, the grounds for the separation being to my mind insufficient. 
IV. — Kota-Maleri Group. 
Overlying the Kamthi group are the Kota-Maleri beds, made up largely at 
the base of red and green clays; fine-grained, speckly-grey sandstones; open 
mottled purple or red and white sandstones; thick-bedded white sandstones, 
with coarse gravel scattered through it in parts or occuiring in ill-defined runs; 
soft and somewhat unctuous .sandstones of various colours; and pisolitic argilla¬ 
ceous sandstones and grits: most of these lower sandstones contain clay galls. 
The clays, and moi'e especially the red ones, are the most conspicuous beds of 
the group, and at the same time form a very striking feature in the surface 
aspect of the country. Over considerable areas, nothing but red soil is to be 
seen, and for many miles between Bibra and Nakalapali, on the high road to 
Sironeha from Chanda, this is the predominant colour. 
The clays are by no means constant in thickness, their most profuse development 
being in the west and the north-west division of the map. In the section exposed 
by the Pranhita, the proportion they bear to the other rocks of the group is small. 
Clays are not so abundant high up in the series as at the lower horizons. 
The dip of the Kota-Maleri group is in conformity with that of the under¬ 
lying series both in the Godfivari and Pranhita sections, but the unconformity 
of overlap becomes evident when the lower boundary is followed for some dis¬ 
tance. In the Memoir on the Wardha valley, I pointed out that this was the case, 
and the testimony is repeated here. 
Associated with the clays are the limestones at Kota, from which the fish 
Lep'idotus and Dapedius were obtained. At Kota the limestones, like the clays, 
are not of con.spicuous thickness; but, like the latter, they become much more 
prominent members of the series towards the north-west; and near Bimpur and 
Itial, 36 miles from Kota, they form a well-marked, though low hill range. That 
the limestones so abundantly developed in the north, and there attEiining a 
thickness of over 100 feet at the least computation, are the continuation of the 
few feet seen at Kota, is, I think, a point fairly established by the likeness 
that the rocks bear to each other, and by the discovery of fish scales at Itial 
similar to those found at Kota. 
I was not able to trace them much beyond the vicinity of Itial, but in the 
other direction, and the further side of Kota, Mr. King succeeded in picking them 
up in the Godavari.
