 Var. NTGHESCKNS, Sowb. PI. 1, fig. 4. 



Surface nearly entirely covered by the chocolate markings.

Shell regularly grooved throughout, spire rather more elevated, 

 not tnberculated, last whorl somewhat convex on the sides.

Dr. Weiiikaiiil' has adopted the name C. pe,]>lum, Chemnitz, for 

 this B lit. that author only happened to be binomial in 



this instance, many of his other Cones being designated by a 

 descriptive phrase ; I therefore prefer to retain the better known, 

 if later name given by Ihvass. This species is in part the C.
