Abstract
These drift-deposits lie for the most part upon a nearly level surface of Lower Keuper Sandstone, overlooked eastward by a range of low Bunter and Permian hills, of which Show Hill and Bushbury Hill are the chief. Other exposures are upon Permian sandstone in the town of Wolverhampton, and upon the Coal-measures of the district adjoining. Bushbury Hill is chiefly remarkable for the number of travelled blocks of granite and greenstone lying around its northwestern base—the side lying most open to bygone arctic and glacial influences. No boulder-clay nor drifted material of other kind is associated with these blocks upon the hills in this immediate neighbourhood. The drift at three localities, viz., Bushbury Junction, Oxley Manor, and Wobaston Big Meadow, had probably a parallelism in time of deposition and agency of formation; though I cannot satisfy myself whether to regard them as the remains of a low terrace-line skirting the valley, or as the result of undercurrents, relaying the derived material in banks parallel with its strike. In the exposure of this drift at Bushbury Junction, where it is an apparently unstratified bed of clay and sand, with an admixture of both rounded pebbles and angular flints, I have met with the following marine shells, which have been kindly determined for me by Mr. J. Gwyn Jeffreys, F.G.S.:— Nassa reticulata, Turritella communis, Purpura lapillus, Littorina squalida, Astarte arctica, Cardium edule, Tellina solidula , and Cyprina Islandica . Rolled shells and other fossils derived from Liassie rocks accompany these, such as Gryphon, Ammonites, Gardiniee,
