conjunction with that of the upper sub-group. They have not yet 

 been traced continuously to the westwards, but appear to occupy a large 

 tract of country between Sipri and Neemueh, the Bundair limestone 

 having been found to occupy most of the ground as far as Chuppra 

 in a traverse from Bundi to Guna. 



Upper Bundair. 

 The ^upper Bundair' sandstone which constitutes the highest member 



of the series is the only one still to be described.

The large spread oi these strata m the jungly 



country between Myhere and the Nerbudda^ forms a very shallow 



basin, along the northern and southern limits of which the strata dip 



inwards from the edges of the escarpment at an angle of 5° or 10°, while 



in the interior of the basin the beds, while gently undulating, are on 



the large scale horizontal. The faulted nature of some portions of 



the southern boundary does not affect this arrangement. The inward 



dip is less marked on the eastern and western edges of the basin, on 



account of the elongated form which the basin possesses. 



A fine section illustrating the passage from the lower to the upper 



Bundairs may be observed in an indentation of the scarp north-west of

In mineral character this rock differs considerably from the Rewah 

 and Kymore sandstones. The beds are generally thinner, varying from 

 6 to 18 inches, though many occur of 3 and 4 feet. It is fine-grained 

 and comparatively soft; in consequence of which the Bundair _scarp seldom
