The above list contains thirty-eight species, all of Avhich are 

 more or less common in the neighboring Gulf St. Vincent at the 

 present day. Some changes in local distribution are apparent in 

 a few species, particularly^ those contained in the calcareous bed of 

 the lower division. In the latter bed Orbitolites complanata is 

 the prevailing foraminifer. This species is still living on some 

 portions of the Australian coast, but has apparently become extinct 

 in the adjoining waters within recent times. 



PLIOCENE. 



A bore put down by the Dry Creek Smelting Company about 

 six miles north of Adelaide yielded artesian water at a depth of 

 320ft. The water stratvim proved to be a white quartzose sand of 

 marine origin and very fossiliferous. On the determination of 

 Professor Ralph Tate the mollusca have a facies that can be most 

 appropriately referred to the Pliocene — a marine formation of this 

 age being vmique for Avistralia. On examination, the following 

 species of foraminifera were noted : —
