Marshall and Murdoch. — Tertiary Rocks near Hawera. 



87 



is five miles to the north of the mouth of the Tangahoe, and the horizon 

 exposed on the beach at that point is about 100 ft. higher than the lowest 

 horizon at the Tangahoe mouth, and is therefore 400 ft. lower than the 

 Waipipi horizon, or. in other words, 4,200 ft. below the highest beds at 

 Castlecliff. 



The great regularity of the stiatification which is so noticeable to the 

 south-east of Waipipi is just as noticeable in the strata exposed along the 

 coast-line to the north-west of that place. There is no unconformity as 

 far as our observations went, and there is no evidence of a stratigraphical 

 disconformity. The similarity, too, of the niolluscan faunas in the localities 

 that have been mentioned is also so great as to show clearly that there is 

 a palaeontological continuity.
