a 
378 HELIX PISANA. 
The sub-var. donnelli is described as large and 
very globose, with a large well-rounded aperture and 
a covered umbilicus. It approximates to H. djerbanica 
in form, but the whorls are not earinate, nor the body- 
whorl subaneular. 
Diam., 20-21 mill. ; alt., 16-18 mill. 
The sub-var. padesiana is elobose in shape, with Fic. 424.—Helix pisana sub- 
six moderately convex whorls, and an elevated spire. — Yat, ¢077e¢2 Pallary. 
Tee pet : E cee bap : Tetuan (after Pallary). 
Differs from sub-var. pisanopsis by its more globose 
form, more conoid spire, and its smaller and flatter last whorl. Diam. 13-18 mill. ; 
alt. 12-16 mill. (See Monogr., pl. xxxi., ff. 4, 5). The variegated colouring of the 
illustrative figure is not a distinctive feature, as type shellsin the Muséum (Histoire 
Naturelle, Paris, are of an uniform whitish colour. 
The sub-var. earpiensis is closely related to sub-var. radesiana, but is less 
elobose with a less elevated spire and a less swollen body whorl. Diam. 15 mill. ; 
alt. 12 mill. (See Monoer., pl. xxxi., f. 21). The colouring of the illustrative figure 
is not one of the characters of this form, which may also be quite bandless. 
The sub-var. donatii is described as depressly tectiform, spire conoid, com- 
posed of six convex whorls, the last large and angulated at the periphery ; said to 
differ from the typical form by its smaller size, its median keel, and smaller aper- 
ture. Diam. 18 mill. ; alt. 14 mill. (See Monogr., pl. xxxi., f. 20). 
The sub-var. dermoi is globosely elevated, the spire composed of six convex 
whorls, the last rounded. Diam. 15 mill. ; alt. 12 mill. (See Monogr., pl. xxxi., 
ff. 7,8). The figures show a form somewhat more depressed than usual, and the 
colouring is also only one of the forms this variety assumes. 
The sub-var. hamadaniea is described as globose in form, with large body- 
whorl, and somewhat elate spire; the colouring is of a dull whitish or rosy hue, 
with yellowish banding, or may be speckled with black. Diam. 14 mill. ; alt. 12 
mill. 
The sub-var. gratiosa is described as very globose and whitish in colour, with 
a few interrupted and pale brown spirally revolving bands above and below. 
Diam. 13 mill. ; alt. 11 mill. (See Monog., pl. xxxi., f. 9). 
The sub-var. lenoleuea has neither been deseribed nor figured. 
The Helix carpiensis, Helix hamadanica and Helix pisanopsis of Let. & Bourg., 
Helix lenoleuca Bourg., Helix radesiana Mares, and Helix dermoi are classed as 
globular or spheroidal, with rounded whorls by MM. Letourneux and Bourguignat. 
Dr. Germain, who has especially studied Helix pisana, as a result of his own 
examinations, enumerates as of globose or normal form, H. bocagei, H. djerbanica, 
H. radesiana, H. carpiensis, and I. donatii, and classing H. hamadanica and 11. 
dermoi as belonging to the elate section. 
It is deseribed by Dr. Germain as rather common and widely diffused, the south 
of France, Spain, Portugal, Corsica, Algeria, ‘Tunis, ete., being enumerated.
