GASTEROPODA. HELICIDZ. 65 
vittata. Tentacula coloris dorsi, ad apices seepissimé rufa. 
Oculi atri. Pes griseus, pallidé olivaceus, rufescente-fuscus 
aut luteus, griseo-rufescens, nigricans, aut viridescente-lu- 
teus ; margine concolore aut pallidiore. 
Shell ventricose, generally rufescent, often pale orange or 
dirty yellow. Whorls five, very slightly striated in the longi- 
tudinal or spiral direction, but more strongly and irregularly 
so in the transverse direction. 
Upper part of the animal greyish-ash colour, olive inclining 
to lutescent, rusty inclining to red orange or dirty-testaceous : 
the grooves between the sculptured eminences olive-brown, 
blackish, or bluish-grey ; the margin of the same colour with 
the back, or paler. The sides are sometimes marked with a 
broad blackish line. Foot grey, pale olive, reddish brown or 
luteous, grey-reddish, blackish or greenish-lutescent. Margin 
of the same colours, or paler. Tentacula of the same colour 
with the back ; their points generally reddish. Eyes black. 
The sculpture of the back is oblong; that of the sides irre- 
gular, and not longer than wide; that of the margin of the 
mantle less impressed, and finer towards the edges. Margin 
of the mantle with a longitudinal impressed line. 
The longitudinal bands of colour are rarely visible in British 
specimens of the shell, excepting on the larger whorl; these 
bands vary in size, and in number from two to five. The gene- 
ral colour of the peritreme is brownish-violet, but it is occasion- 
ally of a pure brown or dirty white. 
This Pomatia, the only indigenous species, is very common 
in most of the chalk and oolite formations of England, and has 
been supposed by many persons to have been imported from 
the Continent for the use of invalids; but its general diffusion 
in a certain soil seems to refute this notion. 
In Austria, where this animal is bred as an article of luxury, 
it is subject to a variety of monstrosities in form ; it is not un- 
frequently reversed ; and is sometimes turrited, in which state 
it has been described by Miller as a distinct species, under the 
name Helix scalaris. See Drap. Hist. des Moll, pl. 5. fig. 21, 
22. Diameter of the base of the shell two inches.
