The spiral ribs, wliicli arc not so prominent on tlic wliorLs 

 as in C. foliatiiin, become very large towards tlie foliacoous 

 varices, on which they are produced, thus giving them a very 

 strongly digitated aspect. On two adjacent ribs of the whorls 

 haltVay between the varices there arc distinct protuberances, 

 Avhich are not to be traced in Gmelin's species. The labral 

 tooth is very strong and large, and excavated on the side 

 towards the aperture, which is of a ])urplish red colour crossed 

 by whitish strij)es running down from the digitations which 

 arm the edge of the labrum within the aperture. It is to be 

 remarked that all the specimens of C. foliatus which I have 

 examined have the labral tooth smaller and convex on the 

 inner side, and not excavated as in M. Bumettli. The latter is 

 of a pale fawn-colour varied with numerous whitish undu- 

 lating streaks. 



C. coreanicunij A. Adams, Proc. Zool. Soc. 1853, p. 72, is 

 an allied species, but of smaller growth, about 2 inches in 

 length ; it possesses the same kind of labral tooth.
