the lower one is moft ufually faint; the two fmalleft volu^ 

 tions are generally fmooth : aperture oval, ending in a long 

 canal ; outer lip even, except where the ridges terminate; 

 pillar lip a little replicated, fmooth; infide livid-white. 

 Length three inches and a half. 



This fhell feems to be fubjecl to great variety : fome are 

 irregularly ribbed, which rife into angulated protuberan- 

 ces on the carinated ridge ; others are flrongly bicarina- 

 ted, without the angular undulations. Mr. Pennant's 

 figure appears to have three plain ridges on each volution. 

 Gmelin quotes a fhell of Martini, which is not unlike 

 our defpeEliLS. Martini feems to confider this as a vari- 

 ety of that fhell, and has given feveral figures, that appear 

 to run fo much into each other, as to favour the opinion; 

 one of which is not unlike the carinatus o{ \\\& Eritijli Zo- 

 ology. If it is a variety of the defpedus, it is rarely found 

 in our feas, except in Scotland ; from whence we have re- 

 ceived it.
