Show 1867-J MR. G. F. ANGAS ON AUSTRALIAN MOLLUSCA. 225 Not uncommon under stones and in crevices of rocks, at low water, in various parts of Port Jackson. Length 3 inches. On comparing the specimens in the Cumingian Collection (now in the British Museum) of C. gunni, Reeve, and C. rostratus, Reeve, I can detect no characters which appear to separate thein specifically from C. striatus, Lam., and I am inclined to regard them all as varieties of that species. Specimens in m y own cabinet from Port Jackson, Port Adelaide, Port Lincoln, and Tasmania seem all to belong to the same species, displaying but slight variations in the angularity and breadth of the valves.
