Resumowards, and we were led to believe from the fauna and composition of the sea-floor that this powerful current swept tbe bottom clear of mud, even at a depth of a hundred fathoms.We have here increased the known marine mollusca of Tasmania by one-eighth.Probably so large a proportion will never again be added in one act.Including fragments, illegible or undetermined forms, the collection amounts to about two hundred and eighty species, of which we record two hundred and fourteen.Representatives of groups other than the mollusca have been handed to specialists, and it is hoped that further reports may appear.Under the giant cliffs of Tasman Island have sailed so many great captains and so many famous naturalists, that the spot has revered memories to inspire the worker of to-day.For here in 1642 passed Abel Janz Tasman in the " Heemskerch " and "Zeehan."After a long interval the ill-fated Marion du Fresne followed him in 177*2.Five years late came Cook in the " Resolution."The " Recherche " bore D'Entrecasteaux with La Billardiere in 1792.And PeYon with Freycinet under Baudin voyaged in the " Geographe " and "Naturaliste" in 1802.Past here again, in 1826, Quoy and Gaimard travelled in the "Astrolabe" under Dumont D'Urville.From the deck of the " Beagle " Darwin saw the huge basalt columns in 1836.Four years later his friend Hooker, under Ross, passed in the " Erebus " and " Terror."The following are the species identified.A star (*) indicates that the species has not been recorded from Tasmania : --
