sandstone rich in fossils, including- corals, oysters and other bivalves. 

 Gastropoda and occasionally Ammonites, occurs below the limestone; 

 but owing- to the hardness of the rock and its mode of weathering none 

 of these fossils can be got out. 



Below the junction of the Sookee with the Huthnee, the latter 

 stream flows chiefly between clifis of sandstone for

The sandstones vary ; at first they are fine in texture, red and yellow, 

 obliquely laminated at the top, and flaggy, interstratified with purple sandy 

 layers. These layers are occasionally shaly, and the alternations with 

 the sandstone very thin. Some of the sandstone beds are conglomeritic. 

 Further down the stream, near Dilwanee, white sandstone pre- 

 dominates. It rolls about, being in general nearly

horizontal. The rocks here dip to the south, and 



the higher beds, including the limestones, again appear in the stream ; 



near Eavar strong slabs of calcareous breccia, containing bone fragments, 



are seen. This bed is perhaps the same as one containing sharks' teeth, 



which is found farther west in the Eajpeepla hills.

tinctly to the lines of bedding, although some slight irregularity occurs 

 along the junction. The sandstone below the trap is very little, if at 

 all, altered.-* At the north end of the s ection are some small faults, 



* This trap is doubtless a horizontal dyke, like some other cases to be noticed. Inter- 

 stratification of traps has not been observed in the cretaceous beds.
