stone (Glyptolepis beds of Scotland), from the adjacent district, and in the attenu- 

 ation of the Upper Old Red (Devonian beds), the Carboniferous limestone and 

 Millstone-grit in the direction of the Malverns. And lastly, in the unconformable 

 position of the Coal-measures, both on the north and south of the range, and of the 

 Permian breccia to both the Coal-measures and overlying Trias, we have further 

 evidence of repeated oscillations of level. 



Similar changes of level affected the Cambrian area of Charnwood Forest. The 

 Upper Cambrian and the whole of the Silurian and Old Eed Sandstone systems are 

 entirely absent. It was dry land in early Carboniferous times, as pointed out by 

 Professor Jukes. It was subsiding, however, throughout the latter part of that epoch, 

 and continued to do so until the close of the era of the lower Coal-measures. The 

 upper Coal-measures are not known to occur in the neighbourhood with certainty, 

 at least the evidence of their presence is not conclusive, and the Permian system 

 not nearer than Ashby-de-la-Zouch, where some " meagre traces" are supposed by 

 Mr. Hull* to occur, forming marginal outliers of the formation. Be this as it may, 

 the area was certainly upraised, and was probably dry land in the early Triassic sea, 

 as shown by the shallow-water conditions which prevailed at the commencement 

 of that period, and by the gradual subsidence of the area which followed during 

 which the Keuper marls closed over it. 



Remarks on the Geology of Parts of the Sinaitic Penhisula. 

 By the Rev. "W. Holland. 



The peninsula is composed of three geological elements. The first and most ex- 

 tensive is the northern table-land of limestone, the Desert of the Tih. The next, 

 the sandstone formation— the great mining district of the Egyptians. The third, 

 the oranite formation, which included the greater part of the south of the Peninsula. 

 Further, the raised beaches, especially on the western side, are of great interest. 

 Tlu' author had obtained specimens of existing shells to the north of Tor, at a height 

 of 20 to 30 feet above the present level of the sea, and large blocks of coral occurred 

 at a still greater elevation. He had also shells from the old bed of the Gulf of 

 Suez, a few miles south of the ruins of Se'rapeon. In following the proposed line 

 of the maritime canal from Lake Tinsall to Suez, he found the desert quite while 

 in many places with beds of shells, and in one part for nearly four hours he was 

 walking across a bed of solid rock-salt, about 4 feet in thickness.

Notice of the Occurrence of certain Fossil Shells in the Sea-bed adjoining the 

 Channel Islands. By J. Gwyn Jeffreys, F.R.S. 

 In the course of his dredging explorations this year among the Channel Isles, 

 Mr. Jeffreys found shells of species, some of which are extinct, and one is not 

 known to inhabit at present the North Atlantic. They were taken with living 

 mollusca, at depths varying from 12 to 20 fathoms, and in different parts of the 

 sea-bed. The specimens in question had the same appearance as dead shells of 

 recent species ; one of them was in a most perfect state of preservation, and evi- 

 dently had not been rolled or transported to any distance from its original place 

 of habitation. They consisted of Potamides tricarinatus, Lam., and P. cinctus, 

 Lain, (both Eocene fossils), a species of Terebratula (or Terelratuli/ia), which Mr. 

 Davidson referred with doubt to T. squamulosa of Baudon (from the Calcaire 

 Glossier), and Rot alia (Discorbina) Trochidiformis of Lamarck, also an Eocene 

 fossil, but larger than specimens from the Bracklesham beds. No tertiary de- 

 posit has been noticed in any part of the Channel Isles ; but the discovery of the 

 above-mentioned fossils in the adjoining sea-bed, occupying an intermediate posi- 

 tion, would seem to connect this district with Hampshire and Normandy, and to 

 show the great extent of the Eocene basin or area which formerly existed. Another 

 species obtained by the same dredgings, near Jersey, was Cerithium vidgatum,
