HELIX POMATIA. 221 
Geological Distribution.—//. pomatiu is recorded on the continent 
from the Pliocene formation, but is better known from the later Pleistocene 
beds ; while in this country it is not known with certainty from below the 
Holocene or Neolithic deposits. 
Prtocenr.—Prof. Brusina recorded this species as found in a Pliocene 
deposit in Dalmatia, but as only a single specimen was ever found, the 
record is doubtful and probably erroneous. 
PLEISTOCENE.—Recorded by Sandberger as not common in the Mid- 
Pleistocene tufa beds of Cannstadt and of Burgtouna, as well as in similar 
beds of Upper Pleistocene age at Weimar, Burgtonna, and Muhthausen, 
all in Thuringia; and by von Ihering from the tufa at Streitberg and 
Ober Taunsbach, Franconia. 
Mr. J. Wilfred Jackson has also found a fine specimen with dart and 
epiphragm in fair preservation among loess material from Endingen, 
Kaiserstuhl near Freiburg, Baden ; and Clessin records immature shells 
from the Upper 'lufaceous beds near Oberalling, Bavaria. 
Ho.ocene.—Hitherto the remains of this species have only been found 
in the counties of Wiltshire, Surrey, and Gloucester. 
In Wiltshire, General Pitt-Rivers records the finding of three specimens 
in 1882 during the excavation of a Romano-British dyke in Shiftway 
Coppice near Rushmore. 
In Surrey, the Rev. R. Ashington Bullen found fragments of the shell 
fairly abundantly to the depth of 2ft. 6in. in the Colley Pit, Reigate, 
remains being found at depths of 1ft. 9in., 2ft., 2ft. 3in., 2ft. 6in., and 
aft. Yin. In the same pit, at a depth of 2ft. 6in., he discovered an early 
form of flint scraper with undamaged edge of Neolithic age, and beneath 
this, at a depth of 3ft. 6in., a young shell and fragments of others were found. 
Mr. L. E. Adams has found specimens up to a depth of 4ft. in the same 
deposit, which extends from Box Hill to Reigate, and probably much 
further. He also found it abundantly in the deposit at Betchworth, 
commonly in the Horseshoe Pit, but only occasionally in the old chalk pit 
near Reigate. 
Tieut.-Col. Godwin-Austen, about thirty years ago, obtained //. pomatia 
with bones of Ovis (sp.) or Capreolus capra and Equus at a depth of 2ft. 
from an Upper Greensand quarry at Reigate, in a mixed deposit of Upper 
Greensand and Middle Chalk, which though thinner corresponds to that of 
the neighbouring Horseshoe Pit, and yielded examples of Terebratulina, 
Rhynconella, Kingena, Echinus, and fragments of Belemnites derived from 
the chalk. 
In East Gloucester, according to Mr. J. H. Burkill, many shells have 
been dug up amongst Roman implements on the site of the Roman villa 
at Chedworth near Gloucester. 
In France, Locard enumerates //. pomatia as first appearing in the 
deposits of the river Sadne, and as present in beds dating from the end 
of the Quaternary epoch down to those of Gallo- Roman times; while 
Norguet records it as found abundantly at the bottom of a well, filled up 
during the Gallo-Roman period at Bouvines in the department of the 
Nord (Norguet, Moll. Nord, 1872, p. 273). 
Bouillet records it as found rarely in the comparatively modern cellular 
Travertine deposits of Auvergne, and in the Aragonite of the cliff called 
“Gazon,” between Coudes and Montpeyroux, Puy-de-Dome.
