that the Shells herein ranked are difperfed 

 among their other Buccina. 



Genus 5. Buccina columella dentata vel 

 plicata. Whelks with a wrinkled or pleated 

 pillar. The Shells of this genus have the 

 inner or pillar-lip wrought with one or 

 more high or prominent tranfverfe ridges 

 or pleats. PI. IV. fig. 3, the Tiara or Pa- 

 pal Crown. 



Thefe tranverfe prominent ridges or pleats 

 pn the inner or pillar-lip, are the ftandard 

 charafter of this genus; for all Whelks, 

 whether beaked, guttered, &c. if the pil- 

 lar is thus pleated, range herein;- and 

 there are of all kinds v/ith this character. 



However, it is very proper to obferve, 

 that it is only the Whelks whofe pillars 

 are pleated, that are to be arranged in this 

 genus ; for there are other families of 

 Shells, as the Perfian Conques, the Mu- 

 |-ices or Rocks, &c. which have their inner 

 or pillar-lip wrinkled or pleated in the 



fame
