direction, but at much lower angles (25° to 30°). The lowest bed of 

 these quartzites is here a coarse conglomerate, containing numerous peb- 

 bles of quartz of considerable size, 6 inches and more in length, of a 

 flattened oval form, the longer axis always being in the direction of the 

 strike of the beds* Above this is a hard grey quartzite, and locally, 

 lying rather in broken disconnected patches, not forming any continuous 

 bed, are some pieces of slates very like some of those occurring in 

 the e Cuddapah series/ 



" Proceeding further north, outside the line of the Ghats, a low ridge 

 extends from south-east to north of the village of Chabolu, composed of 

 quartzites capping the schistose beds. Close to Chabolu are seen quartzo- 

 felspathic gneiss and micaceous and talcose schists and some hornblende 

 schists, striking north 5° to 15° west, twisted and rolling, but dipping 

 generally at a rather high angle to east 10° to 15° north. The quartzites 

 above dip at lower angles, but in the same general direction. The lowest 

 bed is a conglomerate, a siliceous and siliceo-talcose matrix, including 

 pebbles of quartz of considerable size. I have noted this bed as very 

 similar to that seen near Govindapully, but the unconformability not so 

 well marked. The ridge stretches almost exactly in the direction of the 

 strike. 



"There is also a thin capping of quartzite, partly conglomeratic, 

 seen lying on the small hills north-west of Kothapulla and south of 

 Annumpulla. Here there is very little seen, only a few feet covering the 

 top and eastern slopes of the hill. The rock beneath here is a rather 

 massive typical gneiss. 



" As regards the character of the metamorphie rocks generally in this 

 part of our area, there is little to be said of much interest or novelty. 

 As remarked above, typical massive gneiss is but feebly represented. A 

 band of some considerable breadth, generally massive and granitoid, with 

 indistinct bedding or lamination, extends along the east of the Ghats 

 from the Penner to the northern edge of the sheet, with a breadth of 

 2 or 3 and even 4 miles, varying somewhat in character. In the 

 southern portion of this, near Govindapully, &c, hornblendic and mica-
