 SPECIFIC CHARACTER. 



Shell somewhat elongated, pale, with a white band : wreaths 

 striated, with longitudinal undulations : on the -posterior part of the 

 lip a single notch.

The notch in the posterior part of the lip of this shell is 

 singular. By this mark the species may be immediately distin- 

 guished in a collection of British Shells, being perhaps tlie only 

 one of tlic kind found on our coast. This notch, it should 

 however be added, is to be considered rather as the. distinctive 

 feature of a natural family of shells, than as the character of the 

 individual species now before us, the very same appearance being 

 observable on several of the extra-europcan shells of the Murex Genus. 



Our specimens of this scarce, and, as we believe, undescribeJ 

 species, were found on the western coast.
