The same sub-nummulitic rocks continue to the south-westward 

 along the outward boundary of the traps, which here having low undu- 

 lating inclinations to the north and north-west are occasionally exposed 

 by denudation of the overlying rocksj and the soft lateritic deposit 

 containing trap concretions again appears. 



Some of the shaly beds which intervene between the nummulitie 

 and sub-nummulitic groups appear in a stream

1. — Olive, green, argillaceous and gypseous friable shales with 

 bluish and yellow calcareous marlstone bands. (These 

 bands and the upper part of the shales are crowded with 

 Nummulites spira, ifc.) They disintegrate rapidly into 

 fine powder ... ... ... ... ... 25 



These shales, together wdth the underlying group, occupy low 

 ground to the south-west skirting the trap hills, and the outeroj)s of the 

 nummulitie beds above them form a scarp of about 60 feet, edging 

 an extensive plain to the northwards occupied by the latter. On the 

 opposite side of this plain, over which the rocks are generally horizontal, 

 these nummulitie beds assume a gentle inclination to the north-west, 

 and pass beneath slightly rising ground formed of soft shaly beds with 

 lateritic and ferruginous sandstone bands resembling those seen in the 

 synclinal at the Panundrow stream north of Baboa hill. 



In the plain near Kapfoorassir the uppermost part of the nummu- 

 litie beds is composed almost entirely of coral 

 of thTKoree^estuary! ^'^ masses. Further westward in the low Runn-like 

 ground bordering the estuary, calcareous dull 

 yellow raggy beds, largely composed of foraiuinifera and other organisms,
