126 MALLET,, VINDHYAN SERIES. 



Sandstones similar to those described are again found in the Goda- 

 veiy valley, and stretch away to an unknown distance to the south-south- 

 west. The shales and limestones have not been observed here. 



To the south of the Kistna in the Kurnool district, the earlier 

 observers found a series of nearly horizontal limestones, sandstones and 

 shales which, from their general similarity, but more especially from the 

 fact of their being, like the Vindhyans, the matrix of the diamond, 

 were regarded as being equivalent to the sandstones, &c., of Eundelkund. 

 The recent detailed survey of these rocks by the Madras party of the 

 Greological Survey, by whom they have been named the Kurnool series, 

 rather tends to support this conclusion. A full description of the series 

 will be given in Mr. King^s report, which will shortly be published. Many 

 points of resemblance will be observed ; but it would be premature to 

 attempt a correlation of the two formations in detail until our knowledge 

 of the vast stretch of intervening ground is more complete.
