An Introduced Land Snail, fielicella ventricosa, 



Draparnaud. 



Sir Joseph Verco showed a number of small snails col- 

 lected in a garden at Woodville, at the end of last month . 

 They were first noticed about five or six years ago in a bed 

 of petunias, which they completely destroyed by ringbarking 

 the stems rather than by consuming the leaves. They belong 

 to the same species and are of the same size as some snails 

 sent to the Adelaide Museum from Mount Gambler, which 

 were identified as Helicella (Cochlicella) ventricosa, Drapar- 

 naud. Their habitat is the south of Europe and the north of 

 Africa, the Canary Islands, and the Azores. They are found 

 also in Bermuda as an introduction. They have evidently 

 been brought by some means into South Australia, where they 

 appear to be now widespread and numerous. A note of their 

 appearance as a novelty near Mount Gambler is found in the 

 last issue of the Records of the South Australian Museum, 

 vol. ii.. No. 2, April 3, 1922.
