band on the middle of the body, continumg fpirally at 

 the bafe of the fuperior volutions quite to the apex, which 

 is prominent ; at the bafc there are ufually three or four 

 fine circular lines of the fame colour; thefe are fome- 

 times confluent, and the white part appears between in 

 fpots ; others have two or three broader, circular bands 

 at the bafe ; none of thefe, however, run clofe to the 

 umbilicus, which is deep but not large : aperture luna- 

 ted, lip thin, and not reflexed, except at the part clofe 

 to the umbilicus; within pale purplifli-brown, with a 

 white, thread-like elevation round the margin- 



A variety is not uncommon, of a plain rufous-brown 

 colour, with fometimes a dafh of cinereous, obfoletely 

 banded at the bafe, or with a fmgle white, fa/cia on the 

 body ; others wholly of a flefli-colourcd white, with a 

 white belt on the lower volution. Length generally half 

 an inch ; breadth the fame ; but we have received it 

 from Kent, full five-eighths of an inch diameter. 



This and the following fpecies have been confounded 

 together; Da Costa and others have confidered it as 

 the Helix zonaria of Linn ^us, to which we cannot 

 affent, though Gmelin has quoted Da Costa's fliell for 



his zonaria. 



Nor is it the zonaria of Pennant; that author was 

 not acquainted with this fliell, except the plain variety 

 quoted.
