SHELL with more or less distinct spiral bands. 
The var. faseiata s.s., is described as possessing from two to five brown or 
brownish spiral bands on a fawn or reddish ground ; the sub-var. fasciata Baudon 
is identical but has usually only three bands. 
The sub var. zonata Mog. is rufous or yellowish, with five dark spiral bands, but 
is here restricted to shells with the yellowish ground colour (Monog., vol. i., pl. 1, f. 1). 
The sub-var. albeseens is whitish, fasciated or flamed with reddish. The sub- 
var. rufulo-zonata which has a pale yellow ground with translucent reddish banding 
and the sub-var. dutescens Cockerell Mss., described as yellow with pale red-brown 
bands, are practically identical with or sight modifications of the sub-var. albescens. 
Draparnaud would appear to indicate this variety in his Helix aspersa B lutescens 
aut virescens, fasciis pallidé rijis. 
The sub-var. albofaseiata is reddish-brown with a white band at the periphery. 
The banding may be denoted by the formula (128) (45) (Monog., vol. 1., pl. 1, f. 2). 
The sub-var. semifusea has the chocolate-brown handing on the upper side of 
the whorls completely coalesced, the formula being (123)45. 
The sub-var. obseurata is described as dark rufous, with broad but more or less 
indefinite pale brown bands. 
The sub-var. brunnea Bandon (not Gassies) is described as brown with yellow 
spiral banding and ornamentation. 
The sub-var. vireseens Bandon is described as being of a greenish-brown 
ground colour with yellow banding and ornamentation. 
The sub-var. puneticulata is described as reddish with traces of a yellow peri- 
pheral line and numerous punctiform yellow markings. 
The sub-var. monozona sub-var. nov., is of typical ground colour with one 
distinct peripheral black band. Formula 00300.
