a 
440 HELICIGONA ARBUSTORUM. 
The sub-var. jetsechini is more depressed than the typical torm, very thin and 
translucent, and the umbilicus frequently closed, of a deep brown colour with a few 
fleckings, and encircled near the periphery by a broad paler zone, upon which the 
usual dark supra-peripheral band is placed. This form in which the animal is 
entirely black is apparently quite identical with the var. moravica of Prof. Stossich 
(see Monoger., pl. xxxiv., f. 8). 
The sub-var. eorneoliformis is depressed, openly umbilicated, of a yellowish 
colour, with pale flammules, and a dark supra-peripheral band. Though not men- 
tioned in the description, the figure shows a pale peripheral zone, and this is also 
inferred from the statement of its affinity with the var. styriaca. 
CONTINENTAL. DISTRIBUTION. 
Italy—The sub-var. corneoliformis is recorded by Prof. Lessona from Mount 
Viso, Piedmont, at an elevation of 7,500 feet. 
Austro-Hungary—Var. styriaca, Styria, and according to Dr. Servain at 
Salzburg. The sub-var. jetschini is recorded by Ulieny from the Gevatterloch at 
Teplitz near Weisskirchen, Moravia, amongst a rank growth of nettles and Jim- 
patiens noli-me-tangere. Dy. Servain records it from around Salzburg, and large 
specimens from the detritus of the Danube at Musdorf, new Vienna, but he seems 
not to possess a proper appreciation of the characteristics of this form. 
Var. canigonensis Boubée. 
Helix canigonensis Boubée, Bull. Hist. Nat. Moll., 1833, no. 37, p.36 (not of Fagot or Moq.). 
Helix hypnicola Mabille, Bull. Soc. Philom., 1882, p. 7. 
‘““SHELL globose, somewhat fragile, striate, with a greenish epidermis, and 
destitute of any system of colouration, and only ornate with a brown band 
faintly marked on the keel which is almost round.” Diam. 19 mill. ; alt. 14 mill. 
(see Monoer., pl. xxxiv., f. 16). 
This variety shows also the somewhat calcified paler peripheral zone, upon which 
the dark band is placed, and is therefore placed in the present section. 
This variety, of which the original description of Boubée is given, has been 
variously viewed by conchologists ; the usual opinion is to regard it as practically 
identical with the var. zatarti, as is done by Moquin-Tandon, a view with which I 
am unable to avree. 
The sub-var. hypnicola is described as moderately thick and opaque, as of a 
yellow or reddish colour, without marblings, and usually with a narrow peripheral 
maroon band. Diam. 17-18 mill. ; alt. 13-14 mill. (see Monogr., pl. xxxiv., f. 4).

oceasionally found with the type, J. E. Morland; a browner form, the sub-var. 
hypnicola, has been found in the same locality by Mr. Sowden. Barnoldswick, June 
1909, F. Booth. 
CONTINENTAL DISTRIBUTION. 
France—In the Pyrénées Orientales it is abundant at the base of the Pie du 
Canigou, while Dupuy states that it lives abundantly at Costa Bona, some kilo- 
metres above Preste near the source of the Tech. Sub-var. hypnicola, summit of 
Mt. Cenis, Savoy (Servain, 1.c.). 
Italy—Vallone delle Forchioline, above Castel Delfino, at an altitude of about 
9,000 feet (Lessona, |.c.). 
Austro-Hungary—Sub-var. hypnicola, Konigstein, Transylvania ! E. Collier. 
Switzerland—Sub-var. hypnicola, the valley of the Rosenlaui glacier, Canton 
Jerne (Servain, l.c.). Dr. Hartmann cites this form from Straubenzell, St. Gall. 
Scandinavia—Recorded from Lapland by J. Stephenson, Sei. Goss., 1894, p. 166. 
Iceland—Sub-var. hypnicola, rather abundant in the north of the island amongst 
moss and by water courses (Servain, l.c.).
