Notes on a traverse of farts of the Kummummet and Hanamconda Districts in 
the Nizams Dominions, by William King, B.A., Deputy Superintendent , Geolo¬ 
gical Survey of India. 
The country referred to in these notes is a moderately elevated and rather thickly jungle- 
_ , ... . ,, , , . covered tract to the westward of the Godavery river, and 
Country bordering right bank of , . J ’ 
Godavery. generally along, but to tne south of, the 18th parallel 
of north Latitude. 
That part of the tract adjacent to the right bank of the Godavery has been already 
Already referred to in Records. referred to by my colleague Mr. W. T. Blanford.* 
A path traverses the region in a general west-north-west direction from Paluncha in 
Observations mostly made along Kummumct, to Narsimpet in the Pakhal talook some 
path from Palnncha to Narsimpet. thirty miles east of Hanamconda; and it was along this 
route that my observations were made, for except around the few villages, up some side 
paths, or in the dry water-courses, it is, at present, almost impossible to see anything of the 
country owing to the prevalence of thin tree jungle and undergrowth. 
The few people who inhabit this country are of the “ Koi” tribe, which is at present 
more generally confined to the Bastar Territory to the east 
of the Godavery. 
I took up the further examination of this country at Paliincha, in the neighbourhood 
of which place Mr. Blanford had been last season. 
Paluncha is on the coarse sandstones of the ICamthi sub-group already described by 
Mr. Blanford as extending thence down to Ellore in the 
Godavery District. These rocks, however, only extend 
a little distance from the village; and the path to Yellambile passes on to rocks of the 
“Crystalline series,” gneiss of different kinds showing at 
rare intervals out of tho superficial deposits covering the 
low-lying and slightly uneven country. 
Near the crossing of the Kinnersammi Vagri, or a short distance higher up the river, 
thero is a good display of rocks which are not so clearly 
of the gneiss series as those already passed over; and 
these are found to be associated with highly altered quartzites forming the low hill ridges 
lying to the west and north of Yellambile and continuing northwards into the lofty group of 
hills lying between the villages of Sfunderkheil, Oolavanoor, Mullawarum, and Mamla. 
Mr. Blanford has noted (on his working map) that part of this range may be of Vindhy- 
an rocks. The southern flanks, at any rate,' are made up of 
quartzites, slates, and schistose beds, which though they 
have a much more highly altered character than the generality of the Yindhyans, are still 
not sufficiently metamorphosed to be included in the gneiss series. Occasionally, it is true, 
some of the quartzites and schists are remarkably like ordinary well-laminated gneiss; but 
the general aspect of the series is decidedly more Vindhyan in its character. 
The series forms a distinct belt of rocks, having a north-north-east south-south-west

t As a rule, the names of places as they arc given in the sheets of the Indian Atlas, are adhered to in this 
paper when they are found to agree with the names given by the people. In the region under description the 
people say goodium or perhaps goodyim; I have never heard ‘ goodum,’ or gudem.
