A. — The Lower Bhima series. 

 In tlie western part of the Bhima area the sandstones and shaley 

 -sandstones show a considerable variation in color, from white to red, 

 purple or green, with endless intermediate shades. As a rule, the 

 reddish-brown and purple tints prevail near the upper part of the 

 formation, followed by drab and greenish beds, whilst near the base 

 yellowish-green or brown and dirty-grey tints predominate. 



The total average thickness of these arenaceous beds amounts pro- 

 bably to about 100 feet, and they may be best studied along the eastern 

 s f f T' th Dla- ^^^ northern sides of the singular peninsula-like 

 *^^"- plateau of Tirth (Teertu) (see map and section, 



Plate IX). At the eastern extremity of the plateau they are perfectly 

 well exposed in a very clear natural section on the bare hill side, and 

 the above enumerated succession of tints is traceable even from some 

 little distance. The colors, however, are not sufficiently constant in their 

 distribution to aiford a perfectly safe guide as to the relative position of 

 outlying pieces of this sandstone and shale series. 



Some of the sandstones are deserving of a little notice, especially 

 Jambaldinni sand- ^^^ ^®^ ^^ ^ purple gritty sandstone which occurs 

 ^ °°^* at Jambaldinni ( Jumbuldenee) , a village in the 



Muddebihal Taluq, seven miles from Muddebihal and seven and ahalf from 

 Talikot. This bed is largely quarried by the Waddras* for hand mill- 

 stones of a superior quality. The bed is very unusually massive for the 

 Karnul series in this region, the partings of the sandstone being from 

 2' — 3' or more apart. Besides the purple color, which is very decided, this 

 sandstone is characterised by containing a number of bright green grains 

 of small size.

 India.
