In crossing the ‘wall ridge? * of the north-west flank of the 
Oondootla plateau from Chennaganpilly, the following section occurs :— 
Paneum Group (in this ease the ‘ wall-ridge’). 
colored beds of limestone; very fine and compact, 
with ferruginous nodules. (‘ Coralloid’.) 
50 » Irregular beds of limestone of a slightly ‘ coralloid’ char- 
1 L acter; and thick beds stringed with purple chert. 
(O wk shales. O wk shales, (wanting or squeezed out).

Here, the O wk shales have either been squeezed out in the sharp 
twist which the beds have received in this ‘ wall-ridge’, or they were 
never deposited in this part of the field; they show, however, further to 
the west.
