are rather coarse clunchy yellow sands, thick-hodded and only moderately con¬ 
solidated. Of these about 25 feet appear overlaid by about 10 of thinner-bedded 
yellow sandstones of much finer grain with thin greyish shaly partings. 
These are apparently the highest beds', shown in this section, as on proceeding 
along the channel we find them turning up with a considerable dip of 25° to 30° 
to north and north-by-west.” Trom under these again appears the coarser 
thick-bedded yellow sandstone which continues to show along the channel for a 
distance of about 200 yards, with here and there some of the thinner beds ap¬ 
pearing in the banks above. Still following the channel, as it turns south-east 
and east-south-eastwards, these coarser beds continue to appear, having a rolling 
dip to the north-north-west.” From under these rises with westerly dip a strong 
brown ferruginous sandstone which only shows for a short distance, and is the 
last and lowest bed seen in this direction, disappearing at a point due north of 
Namdi (K’aumdee), a quartzo-hornblendic gneiss appearing a very short dis¬ 
tance to the east. A yellow sandstone very similar to the upper beds of the 
section just given appears in bowries and in a little watercourse north-west of 
Namdi. 
The small outcrop west of Talliealli and north of the channel section just 
described shows coarse pebbly ferruginous sandstone. The outlier west-by-north 
of Tripnagad and that south of TTmiaveram show coarse, white felspathic sand¬ 
stone, associated, in the latter case, with a little thin-bedded ferruginous 
sandstone of brown color. At Cutanur, two miles to the west of the last- 
named outlier, a greenish-yellow somewhat shaly sandstone underlaid by a 
coarser yellow felspathic sandstone is exposed in well and tank sections. A 
coarse ferruginous sandstone forming a small patch at the north end of the 
Manapakam tank, four miles south-west of Cutanui’, is the most westerly 
extension of the Gondwiina rocks in this quarter. 
Three miles further south-east and east of the village of Asuapetta, and 
again a mile to the south of the village, “ we find patches of hard conglomeratic 
sandstone containing large pebbles of quartz. This is superficially ferruginous 
and of a reddish-brown color, but when freshly broken of a dull grey. It lies 
in thin beds on the surface of the gneiss.” 
Proceeding south “ along the road between Asuapetta and Trivatur, we 
cross four distinct patches of sandstone, in the most northerly of which a tolerably 
good section is exposed in a supply channel running in 
Jadeji section. to the tank at Jaderi (Bathary”). Here resting on the sur¬ 
face of the gneiss is a hard very silicious close-grained sandstone, but frequently 
containing large pebbles of quartz. Of this there is a thickness of several feet, 
showing only at intervals and not well seen. Above this, passing east along the 
channel, we find a coarse felspathic sandstone of no great thickness (2 to 3 feet), 
* “ From these highest beds I procured the only specimens of organic remains that I was 
able to soenre from this locality. Owing to the soft, crumbling nature of the roch, much increased 
by heavy rains which had fallen recently, it was almost impossible to obtain specimens that would 
bear carriage. Several which I extracted came to pieces in my hands. Those which I succeeded 
in carrying away w'cre Falccozamia ? (FtilopliijllumJ and FterophyVum ? I noted also Tceniop- 
teris and Fecopteris.”
