HYGROMIA HISPIDA. 9 
CONTINENTAL DISTRIBUTION. 
Germany—Sandberger cites many localities in the Lower and Middle Pleistocene 
for this variety, as Heidelberg, Durlach, Bruclisal, ete., in Baden; Frankenhausen 
and Sondershausen in Thuringia ; Priesa and other places in Saxony, ete. 
Switzerland —Sandberger gives as localities the Lower and Middle Pleistocene 
deposits at Aargau.

Helix hispida var. tardigyra Westerlund, Verh. Zool.-Bot. Ver. Wien, 1892. 
SHELL smaller than type ; diameter not exceeding 6 mill. This variety, which 
is said to have a stronger labial rib in proportion to the reduction in size of its 
shell, is seldom very hispid. 
The var. minor Picard s.s., is described as conoid, very small (5 mill. diam.), 
rather thick, perforate umbilicus, and with a rib or tooth about a millimetre long 
at the angle of the columella. The var. minor of Bourgui- 
enat is 6-9 mill. in diameter and 4-6 mill. in altitude. 
The var. minor Moqain-Tandon has the shell much smaller, 
more depressed and white, and is identical with the var. 
y Draparnaud. The var. minor of Sandberger is figured, 
enlarged, and is described as 5} mill. in diameter and 3$ 
mill. in altitude. The var. minor of Pfr. is depressed ; diam. 63 mill., alt. 35 mill. 
The var. minor Germain of same form, but darker; diam. 5-53 mill., alt. 3 mill. 
FiG.39.—H. hispida v. minor 
Sandberger (after Sandberger). 
The var. nana Jeffreys has the shell much smaller, but with a strong labial rib, 
spire depressed. Diam., 5 mill. ; alt. 24 mill. 
The sub-var. nitida is 5-6 mill. in diam., and 4-43 mill. in alt., glossy, solid, of 
a transparent clear fawn, scarcely hispid, and the labial rib visible outwardly. 
The sub-var. terrena is small, globose, and somewhat 
thick-shelled. Diam., 5°3 mill. ; alt., 4°5 mill. 
The sub-var. tardigyra Westl. has a funnel-shaped 
umbilicus, closely coiled whorls, and a labial rib fairly well 
defined basally. Diam., 6 mill. ; alt., 4 mill. 
Fic. 40.—Heltx terrena 
Clessin (after Clessin). 
BRITISH ISLES. 
In the British Isles, it is not common; it is, however, plentiful and very 
characteristic on Afton Down, Freshwater, and Boniface Down, Ventnor, in the 
Isle of Wight; and has been reported from Wiltshire, Hampshire, Somerset, 
Sussex, Kent, Norfolk, Gloucester, Glamorgan, Pembroke, Lincoln, Derby, York- 
shire, Westmorland, and Northumberland. 
In Scotland, it is recorded from Haddington and Fifeshire. 
CONTINENTAL DISTRIBUTION. 
Germany—As a fossil it is recorded by Dr. Sandberger from the Lower and 
Middle Pleistocene deposits of Germany, at Durlach, Achern, Steinbach, and Oos 
in Baden; Cannstadt, Neckarelz, etc., in Wurtemburg. Reported by Clessin from 
‘*Mid-Germany,” and the H. terrena from the older loess of Heidelberg, ete. The 
sub-var. tardigyra from Vegesack by Staudinger. 
Belgium—M. Colbeau reports it from Furnes and Nieuport in West Flanders ; 
and from Brussels and Louvain in Brabant. 
France—Recorded by M. Cardot as very rare at Deville, Ardennes; by M. Picard 
from the Somme ;_ by Mr. Oakeshott for the Alpes Maritimes ; by Dr. Jeffreys for 
Pas-de-Calais; by M. Pascal from Haute Loire and the department of the Seine; by 
M. Taslé from Morbihan ; and by Dr. Germain from Sorges, Maine-et-Loire. 
The sub-var. nitida is rare on Allium on the marshy ground in the forest of 
Fourneau, Mouy, Oise (Baudon, I.c.). 
Austro-Hungary—Reported by Dr. Staudinger from the Tyrol. 
Sandberger records fossil specimens from the Lower Pleistocene of Nussdorf near 
Vienna, with a tooth-like thickening on the basal margin of the apertural rib.
