M. Deshayes has determined to be inhabitants of the northern seas, 

 viz. Natica clausa, which occurs as far north as Spitzbergen ; Fusus 

 Peruvianus, erroneously considered by Lamarck to exist on the 

 coasts of Peru, but which is an inhabitant of the seas at the North 

 Cape ; Tellina proxima, Astarte multicostata. Turbo expansus, Velutina 

 undata, (also on the coast of Newfoundland) ; and Pecten Islandicus, 

 erroneously considered by some conchologists, according to M. 

 Deshayes and Mr. G. Sowerby, to occur in a living state on the 

 coast of Scotland. 



The Cyprina Islandica, which is abundant in the raised deposits, Mr. 

 Smith has not found alive in the waters of the Firth of the Clyde. 



The following summary is given in the paper of shells found in 

 the newer pliocene deposits in the British Isles. 



Marine 190 species. 



Land and fresh water 57 



247 



Of these there are recent British 



Marine species 166 



Land and fresh water 54 



220

Recent in Arctic seas 7 



European and Indian seas 1 

 Extinct or unknown 19

Mr. Smith also mentions the occurrence in the newer pliocene of 

 Sicily, of several species now found living only in more northern 

 European seas ; and he infers from them, that the climate of Sicily 

 was at one period colder than it is at present. Four species are 

 mentioned in the paper, Panopoea Bivoncd, Bulla ampulla, Area 

 papulosa, and Bulbus Smithii. 



A paper was then read, entitled, " Remarks on some fossil and 

 recent shells, collected by Capt. Bayfield, R.N., in Canada," by 

 Charles Lyell, Esq,, V.P.G.S. 



Several eminent conchologists having observed that the English 

 crag contains shells, which seem to indicate a somewhat colder cli- 

 mate than that which now prevails in our latitude ; and it having 

 been supposed that a similar inference may be deduced, with still 

 greater certainty, from the abundant occurrence of many arctic 

 species in the marine newer pliocene strata of Scotland and Ireland, 

 Mr. Lyell was induced to examine carefully a collection of shells 

 procured by Capt. Bayfield, and consisting partly of fossils from 

 the most modern tertiary deposits bordering the Gulf of Saint Law- 

 rence, and partly of recent testacea from the gulf itself. 



The shells were obtained principally at Beauport (lat. 47°) 2 miles 

 below Quebec and 100 feet above the St. Lawrence, but similar 

 species are met with on the north side of the St. Charles, 3 miles 

 from Beauport, and at Port Neuf, 40 miles above Quebec, in the 

 latter instance at heights varying/rom 50 to 200 feet above the level 

 of the river.
