Below the upper tertiary beds of this section some shaly and 

 calcareous thinly bedded sandstones were seen to underlie them uncon- 

 formably at one place^ and some orange, yellow and pink marls were 

 similarly exposed in another spot about a mile further up the stream. 

 They are like those beneath the Nullia sands, supposed to belong to a 

 higher portion of the argillaceous group. 



Along the flanks of the hills east of where the above section 

 terminates, the ground is much overrun with 



Kotree. 



detritus or sheeted with sub-recent calcareous white 

 grit; and at one place north-east of Kotree this rests upon a considerable 

 thickness of coarse river conglomerate, composed largely of trap pebbles 

 and boulders. 



In the Kotree stream south of the village, tertiary rocks similar to 

 No. 14 of the above section abound with fossils of the usual kinds. 



From this slightly rolling plains extend towards the coast, near 

 which they are overspread by alluvium, fringed as usual by sand-hills.
