c. Between the sandstone quarries at Bokhara and Korhadi, 

 granitic rocks have lifted to the surface, with a dip of 30° to S.W., 

 a series of red shaly beds ; and between these and Bokhara another 

 species of green argillaceous strata, lying somewhat more horizontal. 

 The relation of these two to the sandstone beds, from the absence of 

 any good exposure, I have not been able to ascertain ; but they 

 would appear to underlie it. Besides the locality now named, these 

 rocks are developed in the district north of Chanda ; and, as I have 

 been told by Mr. Sankey, the green shale covers an extensive tract 

 of country near Hardagac?, south of the Mahadewa Hills. It is 

 probably the same strata that are found to lie on the west and north 

 of the Nawagaum Lake, and to cross the Bayepur road at Mundipar 

 Ghat and at Jamnapur, near Sakorali. The red shale at Korhadi 

 has yielded the following organic remains : — 



Fossils of c. — A reptilian footmark of one-third of an inch long, 

 and as much broad. Three or four specimens have been obtained, 

 each exhibiting only one print, owing to the brittleness of the matrix. 

 I am not sure that all the impressions are of the same kind. 



On the same specimens that bear these footmarks are seen the 

 tracks of wormlike animals. That the animals forming these tracks 

 have been Annelids resembling Earth-worms will be evident to any 

 one who considers the appearance of the furrows ; the way in which 

 the head has occasionally been pushed forward, and then withdrawn ; 

 the tubular holes by which the ground has been pierced, and the 

 intestine-shaped evacuations which have been left on the surface. 

 Fossil worm-borings have been found in the green shale of Tadac?i, 

 N.W. of Chanda, seventy miles S. of Nagpur. 



The only vegetable organism which has been discovered in the 

 shale is a sulcated plant, which most probably belongs to the genus 

 PhyUotheca ; but as a sufficient length of the stem has not been 

 obtained to display the articulation, its precise character cannot be 

 fixed. 



D. Immediately below the red shale there are found beds of white 

 marble at Korhadi, which have been greatly disturbed and dolomitized 

 by the plutonic rocks above referred to. Similar strata, but pink 

 and blue, occur in the channel of the Pech at Gokala, a little above 

 Parshiwani ; and still higher up at Nawagaum it rises into a chain 

 of eminences, which runs thence westward to Kumari. Following 

 up the river still further, on its right bank we come to a patch of
