height, are very noticeable from the summits of the granite gneiss hills, 

 further west. Despite this uniformity of shape, the combination of hills 

 with the large spreads of water in the Kistna renders the neighbourhood 

 of Bezwada decidedly picturesque ; especially so are the views from the 

 top of Mangalagiri and the Undavilli ridge. 



The connection between the Bezwada series and the adjoining granite 

 o-niess to the west and south-west has not been made out, no section 

 having been found showing them in contact, or even in moderate prox- 

 imity. As seen on the right bank of the Kistna, they appear to overlie 

 the granite gneiss, and they certainly present a newer facies, as if they 

 had undergone a lesser degree of metamorphism. 



Considerable beds of quartzite are associated with the Bezwada beds 

 in the main ridge north of the Kistna, but not a trace of them was 

 noted on the south of the river, and I think the quartzite must have 

 passed into the micaceo-felspathic schist, as it so often passes, in the 

 south of our metamorphic area, into true mica schist. 



We must now return to the western band of the schistose gneisses, 



The western schistose wnicn deludes the northern extensions of the 



gneisses. several micaceous, hornblendic, and quartzose 



bands described above as forming the various ridges and valleys lying 



between Pamur and the eastern base of the Vellakondas. 



The band of granitoid gneiss to which I gave the name of the 



Chendra Sekharapuram band, disappears to the northward of the village 



of Immedesheruvu, under the alluvium of the Pal-eru and the thick 



spread of red sandy soil, stretching away to the north-east. The rocks 



which then come into sight north of the red soil plain all belong to 



the schistose group, which then occupies the whole area between the 



lofty granite gneiss masses of the Kanieiri (Kun-

northern extension of the Vellakondas. Mica schist is the predomi- 

 nant form of schist in this region, and next to it quartzite, which 

 forms many long and important hill ridges. Hornblendic schists are
