zonata and Helix plaiiospira, are distinguished by Stabile, Moll. terr. du 
Pidm. pp. 50-64, as follows : — 
Helix zonata (Studer) : Alps of Smtzerlapd, Piedmoi^t, an4 Upper Lom- 
bardy. 
2. Helix fastens (Studer, non auct.). 
ot. transalpina: Canton Wallis.

Ijombardy. 
jpielix icliikyomma (\l^di)=fcetens (Rqssm.) : Tyrol, Iplngadin, Krain.

j3. euganea : Euganean hills, in Venetia. 
M. Stabile also states that Heliv hexagyra (Mhlf ^ Villa) has been founded 
on large specimens of H. ^trigella (Drap.) j and that H. galloprovincialis 
(Dupuy) is a good species, identical with II. carthusiana (Drap.), but distinci^ 
from JI. caniianq (Mont.) as well as fi-om H. cartlmsiaqq (Miill.). 
Helix ammonis (A. Schmidt, in litt.) allied to, and replacing the H, eri<?e-\ 
tqmm in Piedmont, Loinbardy, and a part of Ven^ti^ ; if^ distinctive charac- 
ters pointed out by Stabile, 1. (f. p. 4p, 
Helix depilatq (Drap. Tabl., not Vh.y=iedentula. (Drap.). M. Bourguignat 
has given a description of the shell and anatomy in Moll. Grande Ohartr. 
p. 56, pi. 7. fs. 1-12; lie criticises rather severely the anatomical figure 
given by A. Schmidt for II. depilata (C. Pfr.), which species is considei'ed by 
tbe agthpr i4eptipal with the othey on this occasion (p. 58), vrhilst both 
^ye declared to be different on p, 56. — This snail belongs to the species with 
two sagittae. 
Helix juriniana, Bourguignat, Malac. d’Aix, p. 32, pi. 1. fs. 1-5, from Savoy. 
Allied to H. dolopida (Jan) and H. incarqata (Mull.). 
Helix unifasciata (Poiret), var. H. candidula (Studer), is said to bo an 
alpine variation from the French type, with the striae stronger, and the lip 
less thickened. Bourguignat, 1. c. p. 40. Most authors have considered them 
synonymous. 
Helix phorochcetia^ Bourguignat, Malac. Grande Chartr. p. 52, pi. 6. fs. 9- 
14, from the Dauphin^ ; near H. villosa, but smaller. — II. hourniana, Bour- 
guignat, ibid. p. 54, pi. 7. fs. 13-17, from the Dauphin^ j near H. ccelata (Stud.). 
Helix alpina (F. B.) and H. fontenillii (Mich.). M. Bourguignat ha§l
