First figured and described by Lister, who received 
it from Scarborough, Yorkshire. It has been found 
on the coasts of Essex, Yorkshire, Scotland, and Ire- 
land, according to Da Costa; on the Dorset coast, but 
rarely, by Dr. Pulteney; and at — in Durham, 
by the Rev. T. Rackett. 
This shell agrees perfectly with Linneus's descrip- 
tion. Pennant, and every subsequent writer on British 
Conchology, by attending to an erroneous reference to 
Lister’s figure, instead of Linnzus's definition of M. 
despectus, have given that name to this species. We 
have seen specimens of M. despectus from Groenland, 
which correspond exactly both with Linnzeus’s descrip- 
tion “ lineis duabus elevatis" and with his own figure 
in the Iter Westrogothicum ; and they Rnbese to differ 
from any British species hitherto noticed. 
Since this paper was read, Mr. Donovan has correct- 
ed his description of this. species, and has also given a 
| good figure of M. despectus, (t. 180.); though, as he ac- 
knowledges, on too slight authority € to be inserted as 
British. es
