Remarks. — This group consists principally of clays, marls, and 

 sandstones ; but at Mount Caverhill and Mount Cookson it is cal- 

 careous. It occurs only in the southern portions of the North 

 Island, and the northern and western portions of the South Island 

 as far south as Oamaru. Trigonia scmiundulata, M'Coy, of the 

 Miocene rocks of Australia, is found at Awamoa, and T. pectinata 

 at Hampden. The following South-American Miocene fossils also 

 occur in this group, viz. Natica solida, Sigaretus suhglobosus, Tur- 

 ritella ambulacrum, and Limopsis insolita.

Remarks. — This group, which is confined to the central portion of 

 the South Island on both sides of the Alps, consists generally of 

 clays and sandstones ; but at Kokohu, on the Rangitata river, it is 

 more calcareous. The following South-American Miocene shells 

 are found iu it, viz. Natica solida, Turritella ambulacrum, Den- 

 talium giganteum, Oucullcea alta, and Limopsis insolita.
