Animal pallidé rufescente-cinereum, griseum aut pallidé brun- 
neum. Tentacula pallidé nigricantia, aut subceerulescentia. 
Habitat in pratis, preesertim in cretaceis. 
Shell semipellucid, the whorls transversely striolated. Peri- 
treme pale brown ; the incrassated part white. With the ani- 
mal in it, the shell is often beautifullly mottled or marbled with 
fulvescent, more or less mixed with blackish. 
It is found in many of the sandy and chalky parts of Kent, 
Surrey, and Hampshire. It has likewise been observed at Spe- 
tisbury, in Dorset, by the Rev. T. Rackett ; near Hertford, by 
J. F. Stephens, Esq.; and is also found near Cobham, in 
Surrey.

Habitat in cretaceis, circa Dover et Little Hampton, vulgaris. 
Shell semipellucid, the whorls very finely striolated trans- 
versely. Peritreme internally brown, inclining to flesh-coloured, 
the thickened part whitish externally, with a milk-white band. 
Mr. Gibbs first discovered this species to be an inhabitant of 
Britain in 1814, and communicated it to Montagu, who named 
it in his MSS. Helix Gibbsiz. 
Since that time I observed it in great plenty around Little 
Hampton, in Sussex, but of a small size, though adult. Mr. 
Stephens has discovered it of the size figured in this synopsis, 
at Dover, in abundance. 
Animal grey or testaceous, tinted with saffron. Mantle 
sometimes marked with a whitish band, with or without mi-
