BORDERS OF THE RED SEA. 135 



Grosceil, near Nice. At a spot called Grosoeil, near Nice, 

 east of the Bay of Villefranche, in the peninsula of St. Hospice, 

 a remarkable bed of fine sand occurs at an elevation of about 

 50 feet above the sea *. This sand rests on inclined secondary 

 rocks, and is filled with the remains of marine species all iden- 

 tical with those now inhabiting the neighbouring sea. No 

 less than 200 species of shells, and several Crustacea and echini, 

 have been obtained by M. Risso, in a high state of preserva- 

 tion, although mingled with broken shells. The winds have 

 blown up large heaps of similar sand to considerable heights, 

 upon ledges of the steep coast farther westward, but the position 

 of the deposit at Grosceil cannot be referred to such agency, 

 for among the shells may be seen the large Murex Triton, 

 Linn., and a species of Cassis, weighing a pound and a half. 



Uddevalla. The ancient beaches of the Norwegian and 

 Swedish coasts, described in the first volume y, in which the 

 shells are of living species, present more marked exceptions as 

 being farther removed from any line of recent convulsion. 

 They afford evidence of a rise of 200 feet or more of parts 

 of those coasts during the newer Pliocene, if not the Jlecent 

 epoch. 



West of England.- The proofs lately brought to light of ana- 

 logous elevations on our western shores, in Caernarvonshire and 

 Lancashire, during some modern tertiary period, were before 

 pointed out J ; but the data are as yet exceedingly incomplete. 



Western Borders of the Red Sea. Another exception may 

 be alluded to, for which we are indebted to the researches of 

 Mr. James Burton. On the western shores of the Arabian 

 gulf, about half way between Suez and Kosire, in the 28th 

 degree of North latitude, a formation of white limestone and 

 calcareous sand is seen, reaching the height of 200 feet above 

 the sea. It is replete with fossil shells, all of recent species, 

 which are in a beautiful state of preservation, many of them 

 retaining their colour. I have been favoured with a list of 



* I examined this locality in company with Mr. Murchison m 1828.
