Var. virescens ‘l'aylor, var. nov. _ 
The var. virescens is of a translucent greenish tint, with yellow shadings and 
fleckings (see Monogr., pl. xxxiv., f. 10). 
Turton’s Manual, 1831, p. 35, enumerates a greenish-yellow variety. 
A mutation virescens is given by Schmidt without description.

VARIATIONS IN MARKINGS OF SHELL. 
Var. fuscescens Dum. & Mort., Mal. Savoie, 1857, p. 79. 
Helix arbustorum var. marmorata Roff., Ann. Mal. Soc. Belg., 1868, p. 70. 
Helix arbustorum var. efasciata Morch, Syn. Moll. Dan., 1864. 
The var. fusecescens is described as possessing a brown or reddish ground 
colour, but destitute of the dark supra-peripheral band (see Monogr., pl. xxxiv., f. 21). 
The sub-var. marmorata is also bandless, variously marbled with yellow and 
brownish, and with a brownish apex. 
The sub-var. efasciata is described by Steenberg as resembling the typical form 
of the species, but destitute of the supra-peripheral band. 
This is also my var. marmorata, that name being superseded by fuscescens, the 
name bestowed long before by Dumont & Mortillet. 
GEOGRAPHICAL DISTRIBUTION. 
This variety is as widely distributed as the typical form, and frequently found 
with it, but not so numerously. 
Var. rufescens Moquin-T'andon, Hist. Moll. France, 1855, p. 123. 
Helix arbustorum vars. rifescens, boisseria, poiretia and draparnaudia Moq.-Tand. 
Hist. Moll. France, 1835, p. 123. 
Helix dravica Servain, Bull. Soc. Mal. France, 1889, p. 383. 
The var. rufeseens has a clear reddish ground colour with white frecklings with 
or without perceptible bands (see Monogr., pl. xxxiv., f. 19). 
The sub-var. poiretia is distinguished by yellow and white frecklings on a brown 
eround colour. 
The sub-var. draparnaudia is greenish-brown with yellow frecklings. 
The sub-var. thomasia has white frecklings on a grey ground. 
The sub-var. boisseria has a violet ground colour with white sprecklings. 
The sub-var. draviea is described as of a violaceous colour, with a band of the 
same colour, and whitish marblings, and would seem to be identical in these respects 
with the sub-var, boisseria. 
Dr. Turton in his Manual differentiates a variety without bands and marbled 
with white spots, but without citing localities.
