Inhab. dry sandy places near the sea. 
Animal yellowish white ; neck purplish ; tentacles 
long, club-shaped. 
Shell about half an inch in diameter, and not so 
much high, with the volutions a little flattened at 
top, slightly striate ; colour whitish or yellowish, 
rarely without coloured bands, but mostly with seven 
or eight brown circular lines on the lower volution, 
often broken into dots ; the tip black ; these bands 
are very variable ; aperture longer than wide, with 
the margin thin and reflected at the pillar, where it 
half closes the narrow but deep umbilicus ; the re- 
gion of the mouth is generally of a more or less 
intense rose-colour. 
It varies greatly in the distinctness, the strength, 
and the disposition of the bands : sometimes they 
are altogether wanting, and at others (rarely) suffused 
over the surface. It also varies in the colour of the 
throat, which is generally rose-coloured, but some- 
times pure white ; also greatly in size, according to 
the situation ; and also in form, varying from sub- 
globose to subconic, or depressed, as in other species
