CHAP. 3.] KADAPAH FORMATION.—CHEY-AIR BEDS. 179 
beds, while the long easterly part of this ridge shows the threefold 
system of bands at its eastern extremity. 
The pebbles* and shingle of the conglomerates in these outliers 
M de are always either of quartz, or quartzite, with 
occasional fragments of red-banded jasper. The 
fragments of quartzite are sometimes conglomerates themselves. 
The broad belt of Naggery quartzites edging the Chey-air valley 
Strata west of Chey-air 00 the western side consists of the same kinds 
bad of sands, grits, and conglomerates, with bands of 
flags and occasional strips of intercalated slates. Mr. Charles Oldham, 
who alone examined this part of the country, refers to them as follows :— 
He notices the threefold division of the beds in the Naggery and 
Narnaveram hills, &e., and states that a similar sub-division appears to 
exist to some extent along the western side of the field, “a band (more 
or less well defined) of thinly laminated and rather flaggy beds, occasion- 
ally somewhat slaty in character, separates two bands of hard massive 
quartzites, of which the lower is more frequently pebbly and conglome- 
ratic, and the upper somewhat finer and frequently well rippled.” 
The intermediate band of slates is very well defined along the 
Pee ee southern flanks of the Tripetty hills, where a 
second scarp of quartzites is seen well behind and 
above the lower searp of fine precipitous cliffs. 
Taking Mr. Oldham’s notes from the point where he shows that 
Mr. C. E. Oldham’s the calcareous slaty and shaly beds of the Vaim- 
notes pully sub-group have disappeared under the 
quartzite hills east of Goolcheroo, we find the following :— 
* Along the range of hills east and south-east of Veerapully, the lowest bed is a 
hard purplish and grey quartzite, rather coarse and false 
bedded. Over this are more flaggy and slaty beds and some 
indurated shales. On these sometimes rests a little very ferruginous coarse and hard 
Character of sub-group. 
* I have never seen a fair pebble or shingle boulder of gneiss or granite, except in 
the locality mentioned at p. 158, in these or any other quartzites of KADAPAHS or KAR- 
NÜÓrs.—W. K.
