overlaps the perforation. Breadth at the bafe three- 

 quarters of an inch ; height half an inch. 



This fpecies differs effentially from Helix virgata both 

 in fliape and markings ; it is larger, broader in propor- 

 tion to its height, and deprefied on the top ; whereas tliat 

 fhell has always a produced apex, and never more than 

 one belt on the fuperior volutions. 



Mr. Pennant has given a very good figure of this 

 fhell, which he defcribes to be fafciated fpirally with nar- 

 row ftripes of white, dulky, and yellow. Such are not 

 uncommon, and is by far, the moft elegant variety. 



This mufl; be confidered as one of our mod rare 

 fpecies, or at lead extremely local : the only place we 

 ever found it in, was on the rocks that verge the town 

 oi Tenby on thefouth, clofe to the fea; and on the fands 

 to the weft of that place, contiguous to the fliore : in 

 thefe places we obferved it twelve vears ago, and lately 

 procured Ipccimens from the fame fpots : it feems con- 

 fined to a fmall diftricl, as we could not find it elfewhere 

 in the neighbouring country. 



Mr. Rackett informed us, he found it near St. Ives 

 in Cornwall, on the flope of the hill defcending to the 

 town. Mr. Penntant has quoted the H. zonaria of 

 LiNN.EUs for his fliell : but we do not think the defcrip- 

 fcion fufficiciently correfponds, to confider it as fuch.
