{Contribution from the Australian Museum), 
During the preparation of a complete account of the Non- 
iVIarine Mollusca of Australia it became necessary to review the 
known faunulas of the various States, and the present account is 
issued for the use and co-operation of local students. It has 
become evident that there is a much larger fauna than has 
hitherto been recognised^ and that it will be greatly increased 
by renewed collecting. 
The well knowm South Australian conchologists, Professor 
Ralph Tate and Sir Joseph C. V^erco, had both co-operated with 
my predecessor, Mr. Charles Hedley, so that a fairly comprehen- 
’sive collection is available for study in the Australian Museum. 
Mr. Bernard C. Cotton, conchologist at the Adelaide Museum, 
has continued this valuable relationship, and has forwarded me 
a large series of mollusca, so that this essay should visualise our 
knowledge at the present time fairly accurately. 
It is surprising to find that this will be the first attempt at 
a checklist of South Australian Land Shells for over sixty years, 
as Angas published a list in 1875, totalling 28 species only. 
One hundred and thirty years ago the famous French natur- 
alists, Peron and Lesueur, collected land shells at Kangaroo 
Island and on the islands of St. Peter and St. Francis, Nuyts’ 
Archipelago, and these were named and figured by Ferussac 
about 1819 to 1821. Probably the English naturalists with 
Hinders also picked up specimens, but we have no exact record 
of such. Years later that enthusiastic conchologist, Angas, who 
lived in the colony for three years, secured many species, and 
from then onwards Tate took up the task, but he was never able 
to^ furnish the complete account he hoped for. The Horn 
Scientific Expedition to Central Australia brought back a good 
number of land shells, and these were duly described and figured 
by Tate, with some anatomical notes by Hedley. It has been 
found impossible to utilise the artificial boundaries of South and 
Central Australia in this group so that all the forms from these
