HELIX NEMORALIS, 301 
CONTINENTAL DISTRIBUTION. 
Germany—Sub-var. pe//ucens, recorded from Alsace by Meyer. 
France—Sub-var. fenwis, Oise (Bandon, l.e.). Recorded from the Pyrénées by Dr. 
Grateloup ; by Pascal from Bois de Jacques, Enghien, near Paris; and by Moquin- 
Tandon from the lofty mountains near Clermont, Puy-de-Doéme, and Eaux Bonnes, 
Hautes Pyrénées. 
VARIATION IN SCULPTURE OF SHELL. 
Ty s = 
Var. subaustriaca Bourguignat. 
This variety is described by M. Margier as distinguished by its somewhat dis- 
tinetly striate shell. 
CONTINENTAL DISTRIBUTION. 
France—Lecorded by Margier from Grande Chartreuse, near Grenoble, Isere, 
and as commonly found of a large size in a somewhat moist wood, Basses Alpes. 
VARIATIONS IN COLOUR OF SHELL. 
The section to which the uniformly coloured shells belong has been distinguished 
by Moquin-Tandon (Hist. Moll., 1855, p. 162), as var. unicolor ; by Picard (Moll. 
Somme, 1840, p. 183) as var. concolor ; and by Albin Gras (Moll. Isére, 1840, p. 29) 
as var. infasciata; it embraces all unicolorous unbanded shells and all shades 
of colouring. It also includes the Helix nemoralis of Sheppard, who regarded 
the unicolorous as specifically distinct from the banded forms. 
Var. albina Mogquin-Tandon. 
Helix nemoralis var. albescens Picard, Moll. Somme, 1840, p. 184. 
Helix nemoralis var. albina Moquin-Tandon, Hist. Moll., 184d, ii., p. 162. 
Helix nemoralis var. alba Baudon, Moll. Oise, 1862, p. 19. 
Helix nemoralis var. pseudo-albina Locard, Mal. Lyonn., 1877, p. 30. 
Helix nemoralis var. albescens Cockerell, Nat. World, 1885, p. 1. 
Helix nemoralis var. purpurascens Cockerell, op. cit., p. 235. 
Helix nemoralis var. virescens Westerlund, Syn. Moll. Extram., 1897, p. 57. 
The var. albina of Mog. (but not albinos of Charpentier) is described as white. 
The sub-var. albeseens of Picard is yellowish-white or whitish; the adbescens 
of Cockerell and the subsequently differentiated var. purpurascens of the same 
author are whitish or yellowish-white with a tinge of purplish or purplish-brown 
on the last whorl near the aperture. 
The var. virescens Westerlund, which has been described by Prof. Cockerell as 
being of a pale greenish tinge, white at the sutures, and with a white lip, may be 
regarded as an interesting modification of the var. albina. 
The sub-var. pseudo-albina is whitish with a very clear grey band. 
It is also the var. albida inornata, var. leucostoma albida inornata, and the 
albida quinquefasciata of Pirona. 
Albine shells are, according to Dumont and Mortillet, exclusively found at 
Meylan near Grenoble, Isere, and the same feature quite predominates on the more 
lofty parts of the banks of the river Arve in Upper Savoy. 
As modifications of the albine form may be registered the following band variations 
which have been distinguished and named :— 
12345 var. bornea Mog. 10345 var. chemnitzia Moq. 
123(45) var. ducrostia Locard. 000:: var. gualtieria Moq. 
33 3:: var. milleria Mog. 00300 var. rissoa Moq. 
Mr. J. Hawkins, of York, has recorded that out of forty-six examples found 
upon coltsfoot ( Tussilago farfara), thirty-two were white, and that the specimens, 
both of H. nemoralis and HH. hortensis, found living on the ash ( Fraxinus excelsior ) 
are principally pale coloured.
