PLATE CLXIX. 



FIG. II. 

 MUREX EMARGINATUS. 



NOTCHED-LIP PALE MUREX. 

 SPECIFIC CHARACTER. 



Shell somewhat elongated, pale, with a white band : wreath* 

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

 lip a single notch. 



Murex Emarginatus : testa sub-elongata pallida fusca alba: 

 anfractibus striatis longitudinaliter undulatis labio 

 postice emarginato. 



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 the only 

 one of the 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-european shells of (he Murex Genus. 



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

 ^pecies, were found on the western coast.
