[Note. — The majority of the foregoing species has been pre- 

 sented to the Museum of the School of Mines. — R.T.] 



The species and individuals are few in number ; but, consider- 

 ing the very small bulk of the material under analysis, they are 

 proportionately rich. All, with one exception, are living in South 

 Australian waters, and are commonly cast-up on our shell 

 beaches. The exception is a varietal form of a somewhat common 

 littoral shell — Cyclostrema micans. 



Passing upwards from the Cambrian bed-rock, there are 314 ft. 

 of unfossiliferous beds, more or less carbonaceous. These indicate 

 a land-accumulation. Whether or not, they are virtually cotem- 

 poraneous with the overlying marine-beds, or are on the same 

 horizon as similar beds passed through in the Kent Town-bore,*
