 are as follows : —

Of the thirty molluscs in these lists, seven, or 23*3 per 

 cent., are still living. 



Pareora Biver. 



Stratigraphy . 



The sections at the lower and upper ends of the Pareora 

 Gorge are so obscure as to be of no value for the determina- 

 tion of the relations existing between the beds containing 

 what has been known as the Pareora fauna and the Oamaru 

 Stone. 



At White Kock River, higher up the valley, the Oamaru 

 Stone is absent, but the fossiliferous clays and sandstones 

 exposed there rest upon the basement rock of the district. 



Fossils. 



From the sandstones at the lower end of the Pareora 

 Gorge, on the south side of the river, in a steep face near the 

 road, where the strata are interbedded with hard calcareous 

 layers, I collected the following forms : — 



1. Ancitla hebera, Hutton. 



2. Natica darioini, Hutton. 



3. Turritella rosea, Quoy and Gaimard. 



4. Turritella cavershamensis, Harris.
