Tliey contain small fish scales, indefinite fragments of bone, a few- 

 small gastropods and bivalve shells, and some carbonised vegetable 

 markings. 



These beds^ though clearly interstratified, do not occur between any 

 two very distinct regular flows, those with which they are associated 

 being porphyritic basalt and amygdaloidal trap, in places decomposed. 



North-west of this place the traps appear to have been locally thin, 



as a small patch of the Jurassic rocks is exposed not far from some of 



the overlying sub-nummulitic laterites, either forming a narrow 



synclinal or more probably let in by a fault. In the lateritic (? volcanic)

were observed, several feet m diameter, the centres 

 being formed of basaltic trap surrounded by successive coatings of 

 decomposed looking and ferruginous trappean rock, gradually approxi- 

 mating to the nature of the bed in which they are enclosed. 



The river which passes Dharisieu, not far from this, runs through 

 Jurassics, trap, and coarse, rugged, ferruginous and light yellowish 

 sandstones with white sandy and shaly beds, dip- 

 ping to the south-west at 20°, but with a tendency to become horizontal. 

 Between these and the laterite before mentioned a thin band of trap 

 intervenes; its stratification could not be clearly seen, but the overlyino- 

 laterite had a high dip to the south of west. 



Further down the stream its bank exposes the white nummulitie 

 Ash in the suh-num- rocks. And nearer to Panundrow, some of the 



mulitic beds. i , •, „ ., , 



lower beds ot the sub-nummulitic series are of 

 thick, greenish, concretionary, cellular, and ferruginous ash, shaly in 

 places, and sometimes of oolitic aspect, with some few carbonaceous spots. 

 In such a position as to overlie these, on and in the north bank of the 

 stream are gray gypseous clays weathering greenish, containing laro-e 

 bones and fragments of bivalve shells, some ferruginous layers beino-
