HYGROMIA HISPIDA. 31 
Var. fusca Moquin-Tandon. 
Helix hispida vars. fusca and cornea Moquin-Tandon, Hist. Moll., 1855, p. 224. 
Helix (Trichea) sericea var. fusca Wattebled, Journ. de Conch., 1889, p. 323. 
SHELL of a clear brown or horny tint. 
The var. fusea Mogq.-Tand., s.s., is described as of a clear brown; the var. fusca 
Wattebled is thin and of a very dark horny-fawn colour; the var. fusca Westerlund 
is described as ‘‘dark brown.” 
The sub-var. cornea is described as of a pale horn colour. 
Westerlund describes vars. cornea and fusca as never of a rufous-brown colour.

CONTINENTAL DISTRIBUTION. 
France—Var. fusca Mog. is cited as rather rare about Lyons in the Rhéne and 
Sadne valleys by Locard, and by Pascal as occurring in gardens of the Grand 
Montrouge, Orly, Choisy-le-Roi, Villiers-sur-Marne, ete., in the environs of Paris. 
The sub-var. fusca Wattebled is common on the ramparts of Auxonne, Cote dOr. 
The sub-var. cornea is recorded as rare on the mountains of the Bugey and the 
Colombier, Ain, by Locard; the var. fusca and sub-var. cornea from Hérault by 
Dubrueil ; and by Pascal from Arcueil-Cachan and gardens of Grand Montrouge 
in the environs of Paris. 
3 VARIATIONS IN CHARACTER OF SHELL. 
Var. albocineta Taylor. 
SHELL showing a pale and somewhat more heavily calcified peripheral band. 
This variety, which is probably atavic, retains the calcified area separating the 
upper and lower group of bands probably existent in the ancestral form. It is 
perhaps more frequently found in the more remote or isolated parts of its natural 
range than in its assumed area of origin, and this is rendered more probable as 
Prof. E. von Martens, of Berlin, in alluding to the reported occurrence of pale- 
banded specimens of H. hispida, remarked that he knew of no banded H. hispida. 
In the British Isles it has been recorded from Somerset, Suffolk, Cambridge, 
Lincolnshire, and Derbyshire in England; Perthshire in Scotland; and Dublin, 
Meath, Louth, Londonderry, and Kildare in Ireland. 
On the Continent it has also been found by Mr. L. E. Adams at Libau, Courland, 
Russia; and it is also, according to M. Mortillet, the Hedicella prevostiana of Risso, 
from the Alpes Maritimes, France. 
Var. morchi Westerlund, Fauna Binnenconch, Suppl., 1890. 
SHELL spirally lineate beneath. 
Iceland—In gardens, Thorshamn (Westl., Syn. Moll., 1897, p. 49). 
Var. sericea Draparnaud (not Jeffreys). 
Helix sericea Draparnaud, Tabl. Moll., 1801, p. 85. 
Helix hispida var. subglobosa Jeffreys, Brit. Conch., 1862, p. 199. 
The var. sericea Draparnaud is described as somewhat globose, subdepressed, 
clear horn colour and yellowish, thin, transparent, slightly carinate, very lightly 
striate, clothed with long yellowish recurved hairs. Spire 45-5 gradually increasing 
whorls; aperture lunate, higher than broad ; peristome simple, or with a very slight 
internal rib, which is visible through the shell as a yellowish band ; the peristome 
slightly reflected around the very narrow umbilicus. 
The sub-var. subglobosa Jeffreys is described as more globular, much thinner, 
horn colour or white, and umbilicus very small. 
Though H. sericea Drap. is figured by Lehmann as differing from H, hispida in 
possessing tricuspid median teeth, while those of H. hispida are shown as unicuspid 
only, yet this assumed difference is probably founded on some error, as British 
specimens do not show this divergence.
