SANDSTONE SERIES. 15 



bonaceous* bed at Bokhara. This I could not find ; here, as elsewhere, I 

 was struck by the absence of carbonaceous matter even in the impres- 

 sions of fossil plants. 



Of beds below the hard band of grits, very little can be seen. Qn 

 the road from Bokhara to Lonhard, eoarse fels- 

 pathic sandstones are exposed ; thence to Gumthula, 

 where metamorphics occur, all the surface is covered by alluvium. East 

 and south-east of BokhS,raj also, no rocks are seen, the last place where 

 Kdmthi beds are exposed being nearly due south of the village. From 

 this spot the trap boundary sweeps round to the south, and when 

 sandstones again appear below it near Takli and Nagpur, they belong 

 apparently to a different series of beds, which will be described presently. 



But if, instead of following the trap boundary from south of 

 Patau Saongi to Bokhara, the strike of the isolated

hills already described as extending from Chanda 

 to Chieholi be followed, after passing over a considerable tract of 

 alluvium on the banks of the Kolar river, a very interesting low rido-e 

 of rocks is met with, on the same strike as those of Chieholi, exposed 



south of the village of Silewada, and again, on the

same strike, after another intervening tract of 

 alluvium, a second exposure of similar beds occurs just north of the river 

 Kanhan at Kamthi. Between the belt of Kamthi rocks thus exposed in 

 these two localities, and the area occupied by beds of the same group near 

 Bokhara, the metamorphic rocks and Talehirs of Korhadi intervene, ap- 

 parently brought up by a fault. The two localities near Silewada and 

 Kamthi are those from which the bulk of Mr. Hislop's fossils were 



* Mr. Hislop's words are, "the higher laminae . . exhibit., an approxiaiation to the 

 " carbonaceous colour, being quite brown through the amount of comminuted vegetable 

 " matter which they contain" — Quar. Jour. Geol. Soc, vol. xi, p. 557. The bed is ao'aiu 

 mentioned in the same Journal, vol. xvii, p. 347. I cannot help suggesting the possibility 

 of the brown colour being due to iron or manganese.
