a groove or fub-itmhilicus. Length fcarce one tenth of 

 an inch ; breadth full one half its length. 



V/e received this fpecies from Mr. Boys for Wal- 

 ker's fliell above quoted. That author defcribes it to 

 be pellucid white: thofe we have examined were all 

 opaque, and of a dirty-white, or light-brown ; poffibly 

 dead fliells. This is pcrfeftly diftin6l from the preced- 

 ing, being much broader in proportion to its length, 

 more conic, more ftrongly ftriated tranfverfely, and the 

 aperture ftronger, and more rounded.

T. wnth a pellucid, glolTy, white, conic fliell, with 

 four or five volutions; the largeft marked with tranf- 

 verfe, fpiral ridges, half way from the bafe ; the reft 

 finely ribbed longitudinally : volutions nearly flat, but 

 well defined by the feparatingline, which is marked with 

 a very fine fpiral ridge : apex rather obtufe ; aperture 

 fub-orbicLdar, pillar lip turns inward and forms an appa- 

 rent fmall denticle, which in fa6l is a plication or ridge, 

 that runs fpirally fome way up the Columella ; a cbarac- 

 ter in this and the three following fpecies not fubjett to 

 vary like the denticulations in fome other fhells, but is 

 the-conftant formation of the Columella, occafioned by 

 the intortion of the pillar lip. as in the Valuta tornatilis ;
