On some new Tasmanian marine shells

The following new and very interesting species were, for the most part, collected by the Rev. H. D. Atkinson, and, with few exceptions, at Circular Head. An accurate knowledge of that fauna has long been a desideratum, and science may be congratulated on having such an industrious and painstaking collector as Mr. Atkinson settled there. A few other species are from different collectors, as noted at the end of each diagnosis. The list shows the spread of the eastern Australian coast fauna into N, Tasmania; while in the new species the recognised Tasmanian molluscan facies is not materially departed from.
