 Shell an inch and a quarter, or an inch and a half long, and 

 about half as broad ; it is somewhat plaited longitudinally, 

 and transversely ribbed, with the ribs prettily granulated, 

 and their interstices striated in both directions ; the colour 

 is reddish or yellowish orange, with the interstices somewhat 

 violet, or ornamented with white transverse bands, and the 

 varices spotted with white ; from this richness of its livery 

 it has received its common name of the * Footnum.' I 

 have now before me a reddish brown Variety with white 

 bands, but I rather doubt whether it is the same as the M. 

 varicosus of Chemnitz, which has been blended with the 

 synonyms of this species by Gmelin. 



scROBiLATOR. 42. Shell with two nearly opposite 

 furrowed varices, and rather smooth ; aper- 

 ture toothed, and ending at both ends in a 

 channel.
