water forms, and arlded not a few species to our Fauna, 

 the contraction or retusion of surface is lower down and 

 broader than usual, and the dots, for the most part, so run 

 into each other, that the shell seems merely furrowed in a 

 spiral direction by coarse jagged strise. 



The animal has not as yet been observed. 



This rare shell has been taken by the Rev. G. C. Abbes 

 and Mr. E,. Howse, at Whitburn, in Northumberland, and 

 in various depths between ten and one hundred fathoms 

 around the Zetlands (M'Andrew and E. F.). It is an 

 arctic and boreal species. Mr. Searles Wood discovered 

 it fossil in the coralline crag*.
