The Periwmkle is found upon our rocks in great pro- fusion, occupying the zone between high and low water and always being found near the edge of the tide. In former days, the Pheasant-sHells were articles of great price and rarity, somt; specimens almost rivalling the precious wentletrap in the enor- mous sums asked and obtained for til em. Now,, however, that their habitations have been dis- covered and more frequent voyages are made, they have become comparatively plentiful'., although, from the fragility of their structure, a perfect speci- men is not at all common, and will still bring a good price in the conchological market. The Pheasant shells are now found in great numbers on the sandy beaches of several shores, being especially plentiful on the coast of Port Western in Bass's Straits. The high tide sweeps them towards the shore, where they, are left by the receding waters, and seek for shelter beneath the masses of sea-weed that are always flung on the beach by the tide.
