 tituie of the tranfverfe ftriae: in the aperture alfo it is 

 effentially different, not poffeffing the marginated lip fo 

 confpicuous in that fliell. 



The fize is double that of the cojiatus : length rather

Tab. 15. f. 2. terminating in rather an obtufe point, and furniflied with 

 about twelve undulated ribs, interrupted only by a fine 

 feparating line; the interftices between them, at the top 

 of each volution, are formed into fmall cavities, giving 

 that part a fcalloped or denticulated appearance; thefe 

 fingular indentations continue throughout the fpiral di- 

 vifional line: the ribs are croffedby extremely fine, clofe-

 aperture oval, oblique, ffrongly marginated; pillar lip 

 not reflected. Length a quarter of an inch; breadth one- 

 third its length. 



This very elegant fliell we were favoured with by Mr. 

 Bryer, who found it at Weymouth with the preceding 

 fpecies.
