The variegated arenaceous clay is of Miocene age, as it lies 

 between beds of Miocene limestone, the overlying bed containing 

 species of Pecten antiaustralis and P. suh-hifrons, while the 

 underlying bed contains P. antiaustralis, P. sub-bifrons, P. 

 palmipes, Ostrea arenicola, and Spondylus arenicola. This clay, 

 moreover, is similar in its physical characteristics to that of the 

 section two miles south of Wool Bay. The clay of the latter 

 section certainly overlies beds of Miocene age, and, judging from 

 this similarity in physical features, the clay of the coast section 

 is also of Miocene age. 



The yellow sandstone of this inland well section underlies the 

 white rubbly Miocene limestone and contains the fossils — Amus- 

 sium Hochstetteri, Fibularia gregata and other Echinoids, and 

 Dimya dissimilis ; consequently it is of Eocene age. 



The hard compact limestone underlying the yellow sandstone 

 contains only obscure casts of fossils, but among these Trigonia 

 semi-undidata can be recognised and is plentiful.
