t On examining this shell, Sir C. LYELL observed, that it is rather a large variety and differs from the English ones in a slight degree, coming most nearly to the variety of the same species found in the Norwich Crag; that this is interesting, as the Gyrenaconsolbrna,a species now recent in Egypt, is found fossil inl the Norwich Crag.
