This paper coincides in time, and partly in its contents, with 
one published by the Recorder in the ^‘^Malacoz. Blatter 
pp. 131-144, on the same subject, but has a more systematic 
tendency. According to the experience gathered by the Re- 
corder in the East-Indian archipelago, he considered the 
boundary-line between the Eastern and the Europaeo-African 
series of Cyclostomacea more sharply defined than appears to 
be the case from the latest discoveries, by which the presence of 
the European genus Pomatias in the Transgangetic peninsula, 
and of the African Otopoma in Western India, is proved. Never- 
theless the Recorder does not believe that the distinction pointed 
out in his paper is overthrown by a few exceptions.

The author proposes to unite into one species, but to distin- 
guish as varieties with separate names, the following species of 
Helix, previously established by himself or others as quite 
distinet : — 
1. Helix similaris (Fer.) — Varr. H sculptiirita (^ns.') , peguenms (Bens.), 
Zoroaster (Theobald), pilidion (Bens.) (similaris, F4r.), holus (Bens.), cestus 
(Bens.). The author observes that although this species has long been 
^own as an example of a land-shell with a world-wide distribution, the 
degree of difference in form by no means coincides with the degree of local 
distance. 
2. Helix rotatoria (Busch.) — Varr. H. tapeina (Bens.), pliayrei (Theobald), 
arahanensis (Theobald), ahowtongensis (Theobald), huttoni (Bens.), oldhami 
(Bens.). 
3. Helix fallaciosa (F(^r.) — Varr. H nagporensis (Vh.'), (Bens.) = 
propinqua (Pfr.), asperella (Pfr.) ( fallaciosa proper), ruginosa (Fdr.), crassi- 
costata (Bens.), helferi (Bens.). 
4. Helix climacterica (Bens.) — Varr. H geiton (Theob.), pansa (Bens.), 
ornatissima (Bens.), anopleuris (Bens.), suhmissa (Bens.). 
6. Helix infrendens (Gould) — Varr. H capescens (Bens.), tichelli (Theob.), 
castra (Bens.), sanis (Bens.). 
6. Helix tranqueharica (Fabr.) — Varr. H semirugata (Beck), ligulata (Fer.), 
vitellina (Pfr.), hullata (Hutt.).
