PLATE CLXIX. 



F I G. II. 



MUREX EMARGINATUS. 



NOTCHED-LIP PALE MUREX. 

 SPECIFIC CHARACTER. 



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

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

 lip a single notch. 



MuREx Emarginatus: testa suh-elongata pallida fusca alba: 

 anfractibus striatis loneitudinaliter undulatislabio 

 postice emarginafo. 



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

 singular. By this mark die species may be immediately disthv 

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

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

 however be added, is to be considered ralher 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-europeau shells of (he Murex Genus. 



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

 tpecies, were found on the western coast.
