Additions to the catalogue of the marine shells of Tasmania

Read August 8th, 1910.
In the Proceedings of this Society for 1908 I published a list of additional species, and since that date a considerable number of new forms have come under my notice, which it is the object of this paper to place on record.
The greater number of the following species were obtained during the Easter camp-out of the Tasmanian Field Naturalists' Club at Freycinet Peninsula, in March, 1910.
I dredged in Geography Strait and due east from there in 15, 40, 60, and 80 fathoms, the greatest depth being some ten miles off the coast. The nature of the bottom was very similar to that of Cape Pillar, explored by Mr. C. Hedley and myself in 1907, but not quite so hard, and there is probably considerably less current.
Broken up polyzoa was very abundant. As was to be expected, many of the same species occurred which were taken off Cape Pillar in 100 fathoms; but, partly owing to shallower water being explored, and to te station being some sixty miles further north, many new species were taken, and also several most southern records of known Tasmanian shells, previously only known from Bass Strait.
It is my intention to place as complete a series as possible of these new shells in the Tasmanian Museum collection.
