ACCOUNT OF THE SHELLS 



COLLECTED BY 



CAPTAIN SIR EDWARD BELCHER, C.B., 



NORTH OF BEECHEY ISLAND. 



BY 



LOVELL REEVE, F.L.S., F.G.S. 



THE additions made by Sir Edward Belcher to the Molluscan 

 Fauna of the Arctic Seas are greater than might have been 

 expected from the researches already made in that direction, 

 by Fabricius, Parry, Moller, and Loven. Out of forty-five 

 species dredged in Wellington Channel and Northumberland 

 Sound, comprised in the following list, scarcely half of them 

 have been hitherto noted as inhabiting Greenland, and only 

 one-third of them range so far south as our own shores. 

 Twelve of the species have not been hitherto described, but 

 three had been previously known as doubtful.
