strata, and decomposed basalt of different character to that of the 

 basalt in mass. 



I was also informed by Mr. A. Cuttriss, a I'esident of the 

 locality, that basalt occurred in two places in the clifts further to 

 the east. The locality indicated was subsequently examined, and 

 furnished three additional examples of necks, one of them of much 

 greater size than that of Townsend Bluff. For the most part 

 these occupy an area beyond tidal influence, so that their 

 characters are not nearly so well shown as in the smallest, but 

 splendid example to the west. They, however, possess features- 

 distinct from this one, and will be described in detail in their 

 turn. 



For the sake of convenience the necks will be referred to by 

 numbers, commencing with that at Townseml Bluff. 



Volcanic Neck, 1. 



This neck is located at Townsend Bluff, at the rnouth of Screw- 

 Creek, on the beach opposite allotment 2, parish of Drunidlemara. 

 It occurs among Jurassic sandstones, shales and niudstones,. 

 planed down fairly level, and exposed at low tide. It has a 

 roughly circular shape with irregularities, the greatest one 

 forming a pronounced bulge in the south eastern portion. Its- 

 diameter in this direction, as far as visible, is about 25 yards, 

 while a north and .south diameter is about 21 yards. Nearly 

 the whole of the periphery is visible. 



For a considerable portion of its periphery, especially on the 

 north, west and .south there is a nai-row shell — if it may be so 

 called — of a finely vesicular scoriaceous basalt, or nuid bnsalt. 

 This has a laminated appeai-ance, the jointing being vertical, or 

 parallel with the wall of the neck. This shell stands up above- 

 the general level of the neck, owing to its greater resistance to- 

 decomposition and wave action. Owing to its jointed character 

 it is inipossible to obtain a museum specimen, and it weathers- 

 into a ragged surface. This shell is only a few inches thick, but 

 similar material, though quite decomposed, and still exhibiting 

 its laminated appearance extends for some few feet into the neck. 

 There are, however, several isolated patches of the hard rock in 

 the body of the neck, the largest one occupying the visible south-
