HELIX NEMORALIS. 311 
The snb-var. eineta (//elix cincfa Sheppard) refers strictly to the one-banded 
form 00300, which was regarded as a separate species. The sub-var. unifaseiata 
Picard is described as possessing a single band only, either simple or compound, and 
may be expressed by the formule 00300, 0(23)00, ete. 
The vars. sexfaseiata Picard, septemfasciata 
Moquin-Tandon, oetofaseiata, novemfasciata, 
decemfasciata and duodecemfasciata have six, 
seven, eight or more bands respectively ; these sup- 
plementary bands are, however, not real additions 
to the normal number, but due to dismemberment 
of one or more of the regular bands consequent on 
a disruption of the pigment cellules on the mantle 
margin of the animal, and this disintegration almost invariably takes place with 
the peripheral bands, and only rarely from the splitting of the outer ones. 
The sub-var. mista is described as typically a heavily and dark-banded shell 
upon a pale ground tint, which is neither bright in colour nor definite in shade, but 
which in the opinion of its authors shonld be classified with var. rubedla. 
The sub-var. intermedia is described as having a rounder aperture, and as being 
of a pale straw-yellow colour, with formula 10345, the last more closely eneireling 
the umbiliens as in H. austriaca, and thus linking the two species. 
The sub-var. pseudoaustriaea is described as strong-shelled, and as showing 
relationship with //. austriaca in the basal banding encircling the umbiliens more 
closely than in typical /H/. nemoralis; the similarity is still further shown by the 
wide and coalescent basal banding.

ENGLAND AND WALES. 
Hereford—Sub-var. mista, common (Boycott and Bowell, l.e.). They also report 
sexfasciate specimens of var. /ibe//ula with formule 1238345, 123445, 123% (45), and 
(123)* (45); of var. rwbel/a one specimen with formula (12)3%45 is reported ; and of 
sub-var. mista 123%45, 125545, (12)*345, 1(23)«45, (12)3%45, (123) ~(45), [1(23) «45], 
[(12)*345], and [123345], while several other theoretically sexfasciate specimens are 
detailed in which the duplication of bands coexists with the suppression of one or 
more of the normal five. 
Lincoln—Mr. J. fF. Musham reports sexfasciate specimens of the var. /ibellula 
from this county, amongst them 128s(45), and 123s(45), in addition to several speci- 
mens with duplicated bands, in which one or more of the normal five are suppressed. 
Of the sub-var. carne he possesses the novemfasciate form, which he reports as 
1esgase7s, and of sexfasciata 1253 (45), and 1234(45), besides several with split 
bands, but deficient of one or more of the normal five. 
York S.E.—Sub-v. sexfasciata 123545, Settrington lane, Norton, B. B. Woodward. 
FOREIGN DISTRIBUTION. 
Germany—Sub-var. pseudoaustriaca, Thuringia (Clessin, |.c.). 
Sub-var. sexfusciata, cited from Chemnitz, Saxony. 
France — Sub-var. sexfasciata, recorded from Toulouse, Hante Garonne, by 
Moguin-Tandon ; by Paseal as less rare in Hante Loire than about Paris ; from the 
Somme by Picard ; and by Grateloup from Paris, and Moissac, ‘Tarn-et-Garonne. 
Sub-var. septemfasciata, a single example from north of France (Moq.-Tand., |.c.). 
Sub-var. nigrescens, cited by Dr. Grateloup from the Landes at Dax. 
Sub-var. /mperfecta, cited for Alpes Maritimes by Risso. 
Sub-var. interrupta, for Haute Loire and environs of Paris by Pascal. 
Austro-Hungary —Sub-var. inferrupla, Stussiner, cited from Laibach, Carniola. 
Sub-var. intermedia, Brenner Pass, ‘Tyrol (Rossin., 1.c.). 
Portugal—Sub-var. quinguefasciata, a common form at Coimbra, A. Nobre. 
Switzerland—Sub-var. sexfasciata vecorded by Charpentier, at Dévens, Vaud. 
Sub-var. imperfecta recorded by Sandberger from the Swiss Jura, and several 
localities about Laufenburg, near Geneva. 
United States—Some hundreds of supplementary band variations lave been 
recorded from Lexington, Virginia, U.S.A., by Prof. Cockerell, Prof. Howe, ete., 
the most remarkable being the duodecemfasciate variety [112238444595) which 
shows seven additional bands; other noticeable but commoner forms are the 
decemfasciate, the novemfasciate, the octofasciate, the septemfasciate, and the 
sexfasciate shells, of which the following formule are respectively representative : 
((12)*33)x x(4(55)), (12)33(33)3(45), 123%xX4( +5), (12)(33)* (45), and *12345. 
In Pennsylvania a number of half-grown bandless specimens were liberated at 
Blairsville, and have prospered there; the locality, however, now yields a prepon- 
derance of banded shells.
