A worked Flint from the Gravel-beds (? Pleistocene) in the Valley of the Tomb of the Kings, near Luxor (Thebes), Egypt, ex- hibited by John E. H. Peyton, Esq., F.G.S. Specimens of Voluta Lambertl from the Coralline Crag, and of Cyprina angulata from the Blackdown beds, exhibited by W. H. Dalton, :Esq,.,F.G.S. Upon these specimens the following note by Mr. Dalton was read :--" The attention of the Society being directed to the Blackdown beds, it may be worth while to note a peculiar feature in the specimen exhibited of Gyprina angulata, Fleming, belonging to the Museum of Practical Geology, and brought here to- night by the kind permission of the Director-General of the Geolo- gical Survey. "The valve, lying with its concavity downwards, has but partially imbedded itself in the sediment, and in subsequent silicification a film of chalcedony has been deposited on the free surface of the matrix within the shell. "Similar surfaces are shown by the casts of Voluta Lamberti, Sowerby, also here exhibited, from the collection of Mr. H. Stopes, F.G.S. These were found in a small quarry of the Coralline Crag rock-bed at Aldborough. They show that as the shells lay on the sea-bed, the upper part of each whorl was occupied by gases arising from the decomposition of the animal, to the exclusion of the cal- careous mud, which could only rise to the crest of the arch of each successive suture. Its surface within the shell was not a plane, tike that of the Blackdown specimen, but shows, for each whorl, an upward bulge in the centre, an annular depression near the edge, and a rise from this hollow to the interior surface of the shell, indi- cating the effect of alternating pressures (probably tidal) acting, through the mouth of the shell, on the elastic cushion of imprisoned gases, which would have escaped by the spiral, had the shells been rolled over two or three times only by currents."
