Helix arbustorum var. pallida Westerlund, Faun. Eur. Moll. Extr., ii., p. 89, 1878. 
SHELL usually yellowish, with more or less numerous opaque paler specklings, 
interior of shell milk-white. 
When tenanted by the living animal, the dark body is perceptible through the 
thinner parts of the shell, to which it imparts a greenish tinge. 
This variety, though rarer than the type, isas widely dispersed and ranges with it. 
It is the var. morbosa-albina of Rossmiissler according to Dr. Westerlund, and 
the var. sealvina of Adami according to Herr Clessin. 
The var. flavescens s.s. is of an almost uniform opaque pale straw-yellow, due 
to the close aggregation of caleareous spreckling, without the dark supra-peripheral 
band (see Monogr., pl. xxxiv., f. 12). 
The var. morbosa-albina is pale yellow, yellowish-grey in parts, without or 
with a faintly perceptible peripheral band. 
The sub-var. lutescens is described as pale transparent yellow, with opaque 
straw-coloured marblings, and without band. Inside, the shell is hyaline white, 
variegated with milk-white. Dumont and Mortillet are of the opinion that their 
variety /utescens represents Charpentier’s var. albinos. 
The sub-var. ieterina is described as pale subtransparent yellow in colour, 
sprinkled with greyish, and without band, apex pale greyish. 
The sub-var. pallida Westerlund is described as thin, pale horn colour (seldom 
pale yellowish-white), transparent, with small linear yellow flecks, often arranged 
transversely ; growth lines sometimes white. 
The sub-var. oelandiea has a partially open umbilicus, is pale yellow in colour, 
densely maculate; interior milk-white. Aperture strongly arcuate, with a thin rib. 
Diam. 20; alt. 16 mill.
