A boreal species (from Greenland, &c.) included among our 

 native shells in the various compilations of British Gonchology. 

 The carinatus appeared without any assigned locality ; the ori- 

 ginal specimen, still p^^eserved in Mr. Jeffreys cabinet, is well 

 delineated as the frontispiece to Pennant's fourth volume, ivhere 

 the incipient folds (omitted in Donovan's representation) are cor- 

 rectly indicated. The last named author candidly avowed that his 

 drawing of M. despectus ivas taken from a Greenland example 

 (a sadly worn one still in existence in the same imp)ortant col- 

 lection), but mentions the remark of a friend, that he had seen 

 a shell like it a few miles off the Orkneys. Similarly the dupli- 

 catus, whose shape is more elongated than any specimen we have 

 ever met with, is figured as a boreal species, to illustrate the 

 difference between it and carinatus.
