The above representative section having been compiled from Mr. 

 Fedden's notes and observations made at different 

 places near the hamlet of Joolerai north of Wag- 

 ka-puddur serves to show the general succession of the rocks, but is 

 incomplete with regard to the laterite, which is very strong in this 

 neighbourhood. This was only found resting locally, but directly on the 

 trap, its usual place being just above the beds Nos. 4 and 5, but it is 

 absent where these are best exposed. 



The whole locality is particularly instructive as to the fugitive 

 character of the base of the nummulitic and immediately underlying 

 groups. 



Where the nummulitic outliers rest upon the laterite here, the coral 

 band to the westward of Joonagea previously mentioned is not observed. 

 Neither is the Flacuna and bone bed No. 8 of the above section seen, 

 nor the gypseous and other shales with ten-estrial fossils (Nos. 6 to 9) 

 in which this occurs. The whole of the sub-nummulitic series from 

 3 to 5 inclusive is likewise absent, and the fossiKferous beds south of 

 Baboa hill and in that portion of the series nearer Lukput — or at least 

 their fossils — do not appear, while the laterite itself on which they rest 

 is too capriciously distributed to claim any fixed position in the sub- 

 nummulitic group.
