rows upon the preceding turn. The shell is scarcely so 

 solid as in the last, and is generally a little translucent and 

 glossy. The spire is for the most part slightly longer than 

 the body, and is composed of six ventricose whorls, which 

 appear very prominent and somewhat scalar from the great 

 abruptness of the broadly excavated suture. The body i« 

 short, rounded, and broad ; its basal declination is curved 

 and rather sudden. The mouth is larger and more rounded 

 than in Beanii ; the external pad of the arcuated outer lip, 

 whose internal crenffi are sometimes almost obsolete, is 

 abrupt. Strictly speaking, it is not the suture that is 

 excavated but the base of the preceding whorl. The first 

 three turns are perfectly smooth. 



, Dredged by Mr. M'Andrew, Mr. JeiFreys, and Mr. 

 Barlee, on the west coast of Scotland. Zetland (Barlee). 

 Possibly some of our localities for Beanii may belong to 

 this species. Loven records it as a Swedish species. 



R. PUNCTURA, Montagu. 



Oval-conic, more or less coloured, very finely cancellated by 

 many spiral, and very numerous longitudinal thread-like lines : 

 whorls peculiarly rounded : suture profound, but not excavated : 

 throat perfectly smooth.
