We have only seen one specimen of this shell, which resembles, 

 in some degree, the young of M. pomum ; but the varices are nar- 

 rower, the tubercles smaller, and there is a smooth space just below 

 the ventricose part of the last whorl. The caudal canal is larger 

 and straighter.

The above name, although, we believe, never published, has been 

 applied to this species in several cabinets. The compressed charac- 

 ter of the fronds on the caudal canal bring it near to axicarnis, but 

 the other fronds are much shorter.

It is somewhat surprising that this species should not have been 



distinguished ere this from M. Palmaras^, from which it differs in 



having a smooth inner lip, and in having small projecting fronds on 



the varices between the larger ones.
