lamellata, at present a northern species in these islands, and not known in recent times south of Yorkshire, though since it occurs at Copford, as well as at Barnwell, it must certainly in Pleistocene times have spread at least down to the watershed of the Thames. The single specimen of Vertigo edentula, in Mr. Dewick's collection, is remarkable for being the scarce varietal form (var. columella, v. Martens) which, originally found in Würtemburg, has since been noticed in Ireland.* Balea perversa is represented by a young individual of only three whorls, and hence is put down with a "?"; but a careful * Jeffrey's Brit. Conch.,' i, p. 269. comparison with recent examples under the microscope shows so close an agreement that no doubt exists in our minds on the subject. The remaining addenda do not seem to call for any special notice, nor is it yet time to comment on certain conspicuous absentees. Amongst the species which are still living in this country it may be remarked that the specimens of Limnæa peregra and L. auricularia from these gravels, are very difficult to separate sharply from each other; those attributable to the former species are nearly all very much inflated examples of the variety at one time called L. ovata, but forms seemingly intermediate between the two species are by far the commonest met with. Limax lævis has only lately been recognized as an inhabitant of Britain, and its occurrence in the fossil state has also been overlooked, its shell resembling small forms of L. agrestis. The following names, one of which appeared in Mr. Dewick's list, and the remainder in Mr. Bell's supplement thereto, have had to be withdrawn for the reasons stated : - Helix rufescens,* the York specimen proving to be H. pulchellum now considered as vars. of P. fontinale. nitidum, the specimen so identified being a swollen form of P. fontinale. *Of six specimens attributed to this species in the British Museum, three proved to be H. concinna; whilst the other three, although correctly determined, had manifestly come from the top soil.

ON THE DISCOVERY OF ELEPHAS PRIMIGENIUS, ASSOCIATED WITH FLINT IMPLEMENTS, AT SOUTHALL. BY JOHN ALLEN BROWN, F.G.S., F.R.G.S., &c. Fossils of any kind are of such rare occurrence in the higher drift of the Thames Valley that their discovery should, if possible, be always noted and the remains described. In this instance I have to record the occurrence of apparently the greater portion, if not the whole skeleton, of a mammoth associated with human relics under circumstances of more than ordinary interest. In September last some extensive drainage works were being carried out at Southall, and deep trenches, about three feet wide, for the reception of pipes were made in the drift deposits, often penetrating the surface of the Eocene beds beneath them. Among other places in the district, these cuttings were exposed in the Windmill Lane, a road running from Greenford, through part of Hanwell, across the Great Western Railway to Woodlake, skirting Osterley Park, and thence towards the river. VOL. X., No. 7. 27 Similar excavations were also made in Norwood Lane, which leads from Windmill Lane to Norwood Green, the junction of the two cuttings being near Windmill Bridge, over the Brentford Branch of the Great Western Railway. The remains of the elephant were found in Norwood Lane, about 550 yards from the junction of the two roads, at the 88thfoot contour, and at a depth of 13 feet from the present surface. They occurred in a bed of sandy loam, which is here intercalated between coarse stratified sandy gravel. The gravel above the sandy loam is surmounted by a deposit of brick earth not exceeding a foot in thickness. According to the account given by the labourers engaged in the work, the greater portion of the bones of the fore-part of the animal were either taken out of the "shore" or were seen on the sides of the cutting. I visited the spot a few days after the fossils were discovered, some of which had been thrown back into the excavation, but I obtained a large hand-bag full of them, some of which are now exhibited. Among them are broken pieces of the leg bones, a portion of the jaw, two of the molars, and some remains of the tusks; a part of a third tooth was in my hands, but it was so much decayed that it crumbled into small pieces in transit. In fact, all these remains, in common with most of the fossils found in the higher river drift beds, were so softened by the action of water as to render their exhumation and removal a matter of great difficulty under any circumstances. When they were dried and regelatinized many of the fossils were in too fragmentary a state to admit of their precise determination with certainty, though it is clear that portions of the jaw and fore-leg bones are among them. They are not rolled by the action of the stream, and the joints and articulations are quite unabraded. The molars are in much better condition, although imperfect. They appear to me to have belonged to a rather young animal, as the crown of the best preserved tooth is not so much worn down by use as would be the case in an older creature; the tusks are represented by mere fragments. It is most unfortunate that I was not present when the remains were discovered; the greater part of the latter could then no doubt have been obtained, as the labourers described the tusks as being found extending in a curve from side to side of the cutting, and apparently attached to the skull, some portions of which appear to be among the remains in my possession. Some large bones were noticed on one side of the excavation, |
