SOME TERTIARY FOSSIL MOLLUSCS 
FROM THE 
ADELAIDEAN STAGE (PLIOCENE) OF SOUTH AUSTRALIA 
By BERNARD C. COTTON, CONCHOLOGIST, SOUTH AUSTRALIAN MUSEUM 
Summary 
While working out the macrofauna of numerous water bores sunk in the Adelaide 
Plains by the Mines Department, for agricultural purposes and to provide water for 
pumping into the mains, a number of interesting molluscs were discovered. A few of 
these are described here; also some Abattoirs bore specimens selected by Sir Joseph 
Verco and myself from material donated to the South Australian Museum by H. S. 
Pratt in 1925. The latter specimens bear the inclusive registration number P. 173. A 
few also are described from the Salisbury Bore, 330 feet, from samples in the Tate 
Museum at the University of Adelaide.
