rocks is here exposed. Denudation has produced some very pretty effects in them. Isolated 
conical hills, several hundred feet high, standing out on the sloping flanks of the main range. 
From this eastwards the beds roll over, sloping up on the flanks of the Deka and Mazara 
range. 
These limestones consist, for the most part of soft friable beds of dirty white or very 
light fawn color. Sometimes, however, they arc very dense or even sub-crystalline. From 
among the latter highly ornamental marbles might be selected. In these the sections of 
nummulites and other fossils present a very pretty appearance. 
On the Karvadft range boulders of a peculiar semi-crystalline limestone with green silt 
interspersed were met with, but the position of the bed from whence they came was not 
ascertained. The rock is dense and heavy, and at first looked like an igneous product. 
In places veins of pure white lime, the result of the percolation of water, are of not 
uncommon occurrence. 
Layers and nests of gypsum, too, are sometimes met with. Some long sticks of fibrous 
gypsum (selenite) were obtained in the Hinki valley. 
Fossils in these limestones were abundant wherever searched for. The collection brought 
to Calcutta includes perhaps a hundred different species. The places where I obtained 
these were in the Tnghar valley, Chukerani, Pasta Mara, Kadji, Karvada, and the Barkan 
valley. Besides these I received a number from Captain Sandeman from the Shum plaits 
which is situated some miles south of Saki-Sarwa. 
The following is a preliminary list of the species which were obtained;— 
Nummulites.
