The Oamaru building-stone is not represented in the 

 Waihao district. 



The Mount Harris beds in this neighbourhood contain a 

 fauna which is the same as that of the Waihao clayey green- 

 sands, and, although they rest upon Lower Mesozoic rocks 

 and nowhere overlie the Waitaki Stone, they are referred by 

 the Geological Survey to the Pareora series of Hutton. 



The stratigraphy is not very clear, and leaves room for 

 different interpretations, but the palaeontological evidence 

 clearly correlates these beds with the Waihao Porks, Black 

 Point, and Hampden beds, which are acknowledged by the 

 Survey to underlie the Waitaki Stone.
