Two elements, which have little in common, an inter-tropical 
and an extra-tropical, are included in the marine fauna. The latter, 
for which I have proposed the name of Adelaiaean, extends from 
Melbourne past South Australia, the Bight and the Leeuwin, and 
fades away at the commencement of the coral belt. To it succeeds 
a fauna which I have called the Dampierian, and which extends to 
Torres Strait. Owing to climatic conditions, the fresh water fauna 
is extremely restricted. But the land-snail fauna developes a variety 
surprising in so arid a region, with peculiarities indicating a high 
antiquity and relation to lost land south and west. 
If the early voyagers of the seventeenth and eighteenth cen- 
turies gathered any shells in West Australia, no account has come 
down to us. Thomas Martyn, in 1784, published figures of several 
shells from King George’s Sound, quoted by subsequent writers as 
Australian; but the King George’s Sound of Martyn was Canadian, 
and is now called Nootka Sound of Vancouver Island. 
The earliest conch ological work was due to French enterprise. 
At the opening of the last century (1801 and 1803) Baudin’s expe- 
dition surveyed a good deal of the coast in the ships “Geograp.he” 
and “Naturaliste.” The collections obtained by this party provided 
Lamarck, Montfort, Blainville, Kiener, Chenu, and others with 
material for research. But owing probably to political disturbances 
no official report of the scientific work as a whole was produced. 
Indeed unpublished material from this expedition is said to be still 
preserved in the Havre Museum A In 1817-1820, another French 
expedition in the “Uranie” and “Physicienne,” visited this coast and 
continued the work of their predecessor. About the same time 
(1818-1822) Capt. P. P. King, an ardent naturalist, was exploring 
the coast on behalf of the British navy. A selection of the shells 
lie obtained were described by Ur. J. E. Gray, of the British 
Museum. A well organised expedition, under Admiral Dumont 
D’Urville (1826-1829) visited this territory. Their results were 
elaborately presented in the Zoology of the “Astrolabe.” A collec- 
tion formed by a German scientific traveller, Dr. J. A. L. Preiss, in 
1838 to 1842, were studied by Dr. T. Menke and published under 
the title of Specimen Molluscorum Novae Hollandiae. Unfortu- 
nately several foreign shells had been introduced into this collection 
and misled the author, who gave numerous corrections in the fol- 
lowing year (1844). Several of Menke’s shells, were illustrated by 
Philippi and others by Reeve. A German government vessel, the 
“Gazelle,” called at a few places in 1875, dredging and collecting. 
A collection of shells made in Cambridge Gulf was recorded by W. 
S. Kent in Proc. Roy. Soc. Qland. VI. During the surveying
