Coc Micella acuta Muller. 
(Plate 1, fig. 7, 8). 
Specimens- first received at the South Australain Museum 
from Mount Gambier and were recorded as Helicella {Coc Mi- 
cella) ventricosa , Draparnaud, by Verco in 1922. The species 
is widely distributed in England and the Mediterranean Region. 
It is now well distributed in the metropolitan area of Adelade, 
specimens having been procured in practically every suburb. We 
have also specimens from one suburb, Payneham, taken by 
Mrs. L. A. Elliott, which are typical of the variety bizona Moquin- 
Tandon, with the two characteristic dark bands on the last 
whorl. The shell is turreted much higher than wide, white with 
more or less distinct brown bands. Diameter 5 mm., height 
IS mm. Evidently very prolific, and soon plentiful when intro- 
duced into gardens. 
Helix aspersa Muller. 
The species is all too plentiful, especially around cultivated 
areas. It is said to have been intentionally introduced to South 
Australia for some purpose. There is a perfect sinistral adult- 
specimen in the South Australian Museum, taken locally.
