Fossil Fauna, Table Cape Beds, Tasmania. 149 



p.S. — The Geological Survey of Victoria subdivided the 

 Spring Creek beds, near Geelong, into three, and applied the 

 terms Lower, Middle, and Upper Miocene to these subdivisions. 

 The examinations of this section made by Mr. T. S. Hall and 

 myself enable us to recognise at present only two distinct 

 palajontological zones, and we are of the same opinion as Messrs. 

 Tate and Dennant that the Survey's so-called upper beds cannot 

 be separated from their middle beds. I draw attention to the 

 above in order that there may be no misinterpretation of the 

 earlier portion of this paper, where I have referred to the so-called 

 middle beds at Spring Creek and their probable equivalents, the 

 clay beds of this portion of the section at Spring Creek having 

 yielded a very fair collection of gastropods and lamellibranchs, 

 which has very materially assisted in determining its equivalents 

 elsewhere.
