HELICIGONA ARBUSTORUM., 429 
The sub-var. repellini is described by Moquin-Tandon as much flatter, thin, 
and somewhat translucent. Dr. Servain gives the dimensions of typical shells as 
diam. 26 and alt. 17 mill., and states that it is the var. depressa of Clessin (Exe. 
Moll. Fauna, 1884, f. 106). It has been named var. datewmbilicata by Abbe Dupuy. 
The sub-var. maynardi is described as depressed in shape, of a pellucid, very 
dark maroon, with a brown supra-peripheral band. Diam. 17-18 ; alt. 12-14 mill. 
It is considered by its author to be nearest the var. alpicola. 
The sub-var. vibrayana is described as possessing a depressed shell, with an 
obtusely rounded spire, and showing a constriction near the columellar margin, 
followed by a blunt gibbosity. Aperture horizontally broad. Diam. 24; alt. 17 
mill. Aperture 13 mill. broad, and 10 mill. in altitude.

France—Var. planospirea is described by Gras as rare, at the foot of rocks on the 
Alps on the road from Launtaret, Isére. Sub-var. depressa is recorded as very rare at 
de la Mouche, Rhone, by M. Locard. Sub-var. repellini is recorded by Charpentier 
and Dr. Servain from the Hautes Alpes at Queyras, and especially at Abries, also 
from Bourg d@Oisans, Embrun, the Col de la Traversette by Mt. Viso, and from 
between Grave and Briancon, as well as from the Alps of Dauphiny generally. Sub- 
var. vibrayana, margins of R. Aube at Dienville and Arcis-sur-Aube (Servain, lc.) ; 
Angers, Maine-et-Loire (L. Germain). Sub-var. maynardi, according to Comm. 
Caziot, lives only on rhododendron stems near the plain of Sadour at an altitude 
of about 8,000 feet on the eastern slope of Mt. Vaglieros, Alpes Maritimes, where 
for eight months in the year they are buried beneath the snow. 
Italy—Sub-var. repellini is recorded by Prof. Lessona at an altitude of 7,500 feet 
from Mt. Viso in the upper valley of the River Po, Piedmont, but it had been 
previously observed there by Stabile, though at a lower elevation.

163 mill. 
The sub-var. nazarina is of similar size, but more 
distinetly angulated, of a beautiful straw yellow, with- | 4...

CONTINENTAL DISTRIBUTION. 
Germany—The sub-vars. nazarina and illusana have been found on the banks

Nazaire, Loire Inférieure (Servain, op. cit.).
