little doubt that tbo Aiuiraiu sti-ata are overlying Karutliis, whicb, tliougb this 
is partially concealed and interrupted by the fault, are apparently continued 
in the Arjunguta bill and at Sironeba. No red Maleri clays come in between 
the Anaram strata and the Kamthis of Linganapeta, but true red clays occur 
near Isnai, some 5 or 6 mile.s west-nortb-west, serially at a much lower hori¬ 
zon than the Anaram beds. 
At Ycdlabundun everything is covered up for some miles along the valley of 
the tributary stream, so that neither the Anaram nor the Linganapeta beds are 
traceable with any certainty to the north-west, though the Anaram beds seem to 
be continued in the sandstone bolt underlying the great zone of limestones 
striking away to Mulkalapeta, which, as will be seen further on, I take to be the 
same as the Kota band. 
Thus far, the points gained or advanced in this enquiry are— 
First, that my so-called Sironcha sandstones are of lower Gondwana age and 
j)robably belong to the Kamthi group. They are extremely like those of Aravi- 
Somnapali, which are on a horizon corresponding to that of the beds near Porsa, 
which Mr. Hughes had already determined as Kamthis, a conclusion verified by 
the fossils I afterwards found in them. 
Second, that the Anaram plant shales are locally bottom beds resting on 
Kamthis, and lower in the Kota-Maleri group than the Kota zone of limestones. 
The Kota-Maleei Group. 
The most definite and recognizable strata in the Kota-Maleri series are the 
limestone bands. Hitherto, we have been under the impression that there might 
be only one of these, that of Kota itself, of which the outcrop at Itial (on the 
Jangaon river) was a portion. I have, this season, been at the trouble of look, 
ing up all the outcrops of these rocks, and there is now no doubt at all that 
there are at least three bands or zones; still the evidence is not quite clear ag 
to the course of the Kota outcrop, that is, it is not continuous over the most 
important parts of the field. Indeed, the whole limestone sub-division, or what 
I have previously called the Kota group, is so much broken and interrupted near 
Sironcha that it will perhaps be better to treat of it separately, as it occurs in two 
areas, to the north-west and to the south-east of that town. 
The Franhita area. 
The Kota Band (No. 2).—To the north-west of Sironcha thei’eare, first of all, 
the historic beds of Kota, a mere isolated outcroj) in the left bank of the Pran- 
hita. It is to all appearance the same band as that of Tondala to the east of 
Sii'oncha, and it appears again to the north-west as the great band, with similar 
fish scales, at Katapur, whence it stretches away up to near the bank of the 
Jangaon river at Parwatipet. The lino of the Arjunguta fault may strike 
across between the Kota and Tondala outcrops, so that it is possible they may 
not bo of the same band, though I think they are, being merely stopped for a 
short distance, but there seems no reason to doubt that the Kota and Katajmr 
outcrops are of one and the same band.
