I have been able this year tu trace decisively the bods of Sironclia town 
across the Pranhita into the rising ground culminating in the hill-station above 
Arjunguta. We had, I think, always supposed this to be the case, and the hill- 
station beds had ever seemed to me of a true Kamthi facies, while the ascer¬ 
tained continuity of strata so far cai'rics these bods nearer to the Anaram strata 
Avith their upper GondAvana plant remains. The hill-station beds ai-o brown and 
ferruginous with a decided Kamthi look, and ai-e in part very hard and vitreous, 
haA'ing thus a much older appearance than the Sironchas; however, I actually 
found unmistakoable Sironcha bods merging into these hard vitrcoxr.s bods ; and 
so there is no doubt at all, in my mind, that the Arjunguta bod and those of 
Sii’oncha ai*e the same; while the fonner have the Kamthi facies. The Arjun¬ 
guta hill-station is at the west-south-Avest end of a line of faidts which may be 
said to limit in part the north-Avesteily extension of the Sh’oncha strata, those 
being also cut oS to the south-east, after a length of some 15 miles, by another 
more or less east-and-Avest fault near Ardium on the left bank of the Godavari. 
To the north of the Arjunguta hill-station are the oft-noted Anaram beds 
Avhich yielded the j)lant remains Palissya confeda, and Ghirolepls miinsteri, and 
Avhich I had concluded were overlying the Sironcha beds in natural sequence. 
The sections and exjxosures of rock in this jxart of the country arc not continu¬ 
ous, as they are coAxrod up in the most disappointing Avay by alluvium, and 
there is the fault just mentioned; still a certain connexion of the Sironcha beds 
with others in the Kota-Malcri field is apparent, Avhich Avill ahvays, until fossil 
evidence be found, cast a shadoAV of doubt over the grouping and mapping of 
this series, 
As it happens, the Anaram beds are not traceable in the Arjunguta outci’op, 
but they may bo followed down by the right bank of the Pranhita to a point 
cast-north-east of the hill-station, where the outcrop ceases suddenly, there being- 
nothing hence for a mile or so but the high alluvial bank of the riA-er, Avhich 
bays inland for some distance, lapping round the slopes of the Arjunguta high 
ground. Not only is there this abrupt ending of the strata, but, after pui-- 
suing an even course with a lie of 20° to 30° to the cast-north-oast, they suddenly 
shoAV signs of a sharp bond to the south-south-oast, Avith rough slickensidos and 
much silicious and ferruginous infiltration. Nearly all safe signs of lamina¬ 
tion and bedding are obliterated in the strong silicious infiltrations which sti-ike 
irregularly in a general east-north-east to Avest-south-west run and nearly vertical 
dip. Prom this point to the hill-station there is a decided hard wall or ridge of 
beds much impregnated with silicious and ferruginous matter in the same irre¬ 
gular strips and seams ; Andram pebble beds, jxurplo shales, clays, and sands 
forming this wall and lying to the north of it. 
An important feature about the Aniir-Xm locality is, that in going Avest-south- 
Avest from the vdllage, one pa.sses over softish red lilac and buff sands, pebble beds, 
shales, clays, &c., liaA’ing a tolerably regular north-east lie ; but after about half 
a mile the bods become troubled, rather flaggy, hard, and more and more ferrugi¬ 
nous, Avhen it becomes gradually apparent that one mrxst noAv be on Kamthis. 
Such a succession, in descending order, may bo found up any of the nalas 
to the north-Avest of Anaram as far as Yedlabundun; and thus there seems
