localities near London, also in Kent, Sussex, and in Ireland, the distinction 
seems to me sufficiently marked; the animal is dark, and the foot less 
fleshy than the last; the shell is also dark, and when containing the ani¬ 
mal alive, sometimes appears almost black. 
Helix depilata. Rare and local. My few specimens answer to the description 
in Gray, but Forbes and Hanley regard it as a var. of the last. 
„ rufescens. Common; the white var. is not unfrequent. 
„ virgata. Very numerous in some localities, especially on the chalk. 
,, caperata. Locally abundant. 
,, ericetorum. Very abundant on the chalk. 
Zonites rotundatus. Very common, as elsewhere. 1 have found the somewhat 
rare transparent and colourless variety. 
,, pvgmasus. Rare. 
„ alliarius. Very frequent; occasionally colourless, or of a transparent 
greenish hue. 
„ cellarius. Frequent, but not large. Sometimes colourless. 
,, nitidulus. Abundant. 
,, var. Helmidii. Rare. 
„ lucidus. One locality; the banks of a slow stream. 
,, crystallinus. Rather common. 
„ purus. Less frequent. 
Succinea putris. Well distributed, but usually of small size. 
Bulimus obscurus. Generally diffused, but not abundant. I have found a few 
beautiful specimens of the transparent, almost colourless variety. 
Zua lubrica. Common. Albino var.; rare. 
Azeca tridens. One locality rather beyond my usual range, in moss, upon a chalky 
soil. One specimen of the albino variety. 
Achatina acicula. Rare. 
Pupa umbilicata. This usually common little shell is scarce here; at St. Leonard’s 
and Hastings I have found it in abundance ; and the specimens there and 
elsewhere differed slightly from those few obtained in this district. Here 
the peristome is not so white, nor the tooth so distinct, as is usual among 
the full-grown shells. The very young bear no inconsiderable resemblance 
to Zonites pygmseus, but, of course, the latter wants the ridge or plait 
within the mouth, along the column. 
,, marginata. One specimen found by Lady Augusta Pratt. 
Vertigo edentula. Local, and not abundant. 
„ pygmsea. In several localities; but rare. At Hastings it is not unfrequent, 
and there I have taken the var. alpestris. 
„ palustris. Rare; one locality. The first specimens I obtained were from 
the cases of caddis-worms. 
Balea perversa. Rather numerous in one wood; hitherto I have only found it on 
the beech. 
Clausilia bidens. Well diffused, but not very abundant. Most frequent at the 
roots of hedges, on the chalk. I have taken a few fine examples of the 
greenish white variety. 
,, Rolphii. This very local and, perhaps, rare shell, is found here, but it is 
not common. I have obtained it near Hastings, one of the localities 
indicated by Gray, and I possess several specimens from Ashhurst- 
park, near Tunbridge Wells, collected by H. Field, jun., Esq. 
„ nigricans. Common. One curious reversed specimen has been found 
here. 
Carychium minimum. Common. 
Acme fusca. Very rare. 
Lymnmus pereger. Frequent; varying much in form. I have one specimen 
produced to the shape of a succinea, but with the lip spreading over 
a profound umbilicus. 
„ Var. acutus. Occasional. 
„ Var. lacustris. Near the Darent. Also in one locality near St. 
Leonard’s.
