The vars roseaceo-albida and roseola have the last whorl and inside the 
mouth of a rosy tint. (See Monogr., pl. xxx., f. 11). 
The sub-var. rosalba is uniform rosy white, occasionally with a black basal band. 
The sub-var. faux-rosea is restricted to those shells in which the rosy tint is 
confined to the interior of the aperture. 
The var. albida Benoit is described as uniformly whitish, with a rosy mouth. 
The sub-var. phadaniea Locard, judging from the single specimen seen, is of 
medium size, has a somewhat elevated spire, is of a whitish colour, with a still 
whiter peripheral line, and a rosy mouth. (See Monogr., pl. xxxi., f. 19). 
The sub-var. subpisana is described as very ven- 
tricose, with a large and well rounded body whorl. 
Diam. 20 mill. ; alt. 14 mill. It differs from the type 
by its more swollen shape, more depressed spire, and 
thicker shell. Usually with an uniformly whitish shell 
and pink aperture. 
The sub-var. maechadoi is described as a thin shell, 
with the spire more depressed than in sub-var. barbo- MiG. 438.— Helix pisana sub- 
zana, and as having a more compressed last whorl. staple ain Batre os

almost typical in form, but has a rosy mouth. 
According to Dr. Pfeiffer, it is in part the Helix albina Zelr., described as white 
with a rosy or brownish mouth. 
The rosy tinge inside and around the aperture of this variety and which some- 
times also suffuses the shell generally, is probably most developed in localities with 
sunny aspects, but there would also seem to be some degree of correlation with the 
presence or absence of the spiral fasciation, as the rosy tinge is almost invariably 
most vivid on unbanded shells.
