led Park* to remark that he had satisfied himself " that it was not an 

 uplifted marine platform of erosion." It may be remarked that a 

 section, even on a vertical plane through a coastal platform, parallel to 

 the average direction of the coast must not be expected to yield a per- 

 fectly horizontal crest. It ought to show a convex crest opposite to 

 bluffs, where the old coast approaches it, and a concave outline opposite 

 bays, where the old coast recedes. To this initial irregularity there may 

 be added slight variations in the amount of subsequent uplift. Rem- 

 nants of this terrace extend nearly to Cape Terawhiti, and it may be 

 seen also at Te Kaminaru Bay, on the western coast. 



There exists also a higher shelf, which was examined at Tongue 

 Point. It may be seen in fig. 7. Its height is about 450 ft., and, like 

 the lower shelf, it is covered with a layer of water-worn pebbles. Its 

 width at the point examined had been reduced by the cutting of the lower 

 shelf to about 50 yards. 



At Baring Head, on the coast south -eastward of Pencarrow Head, 

 at the entrance to Port Nicholson, similar shelves occur, f and again at 

 Cape Turakirae. They may be seen from the deck of a steamer enter- 

 ing Port Nicholson. The sketch, fig. 8, represents them as seen from

the signal-station on Miramar Peninsula. They are cut through by the 

 revived Wainuiomata. The writer has not examined these platforms 

 closely, but believes they correspond in a general way to those at 

 Tongue Point, the sunken area of Port Nicholson lying between. The 

 highest platform at Baring Head appears to be about 500 ft. above 

 sea-level. It has been shown above that the general outlines of the 

 coast appear to be determined by subsidence of land blocks, but, on 

 the other hand, it cannot be assumed that the whole of the uplift of 

 which we here have evidence is differential uplift along these lines of 

 fracture. At many places on the New Zealand coast marine platforms 

 and raised beaches are known, indicating uplift of varying amount. J 

 McKav has recorded Recent shells on a beach at a height of 500 ft. at 

 Amuri Bluff, about eighty miles south-west of Wellington. If this 

 beach can be correlated with the highest shelf at Wellington it may 

 indicate that the stretch of land between has moved as a whole. The 

 latest movement, which took place in 1855, and was described by
