‘rhe spiral ribs, which are not so prominent on the whorls 
asin ©. foliatum, become very large towards the foliaceous 
varices, on which they are produced, thus giving them a very 
strongly digitated aspect. On two adjacent ribs of the whorls 
halfway between the varices there are distinct protuberances, 
which 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 purplish red colour crossed 
by whitish stripes 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 QC. foliatus which I have 
examined have the labral tooth smaller and convex on the 
inner side, and not excavated asin MW. Burnettii. The latter is 
of a pale fawn-colour varied with numerous whitish undu- 
lating streaks. 
CO. coreanicum, 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.

In the specimens I have examined, the lirations within the

the existence of twelve.
