In young shells the whorls do not decrease gradually, the two 
first being much smaller in proportion to the rest. 
Found abundantly in the summer season by brushing long 
grass and bushes in Middlewood Offton ; and in a grove at So- 
mersham, on the left side of the road leading from that place to 
Flowton. Amongst dead leaves at the roots of grass in Friston 
wood. 
In Essex it is taken upon trees on Wrabness cliff, at Ramsey 
decoy, and in Stourwood. 
. It is not a little singular that the Essex specimens should be 
uniformly darker than those found in Suffolk. The Pupa eden- 
tula of Draparnaud has only five volutions, and possibly may be 
the young of this species.

Under stones and pieces of wood at Levineton, Spexhall and 
Offton, but by no means common. 
In Essex, at the roots of grass by the River Stour; at Wrab- 
ness near Bradfield-bay ; and in the open part of the Glebe 
grove, whence a specimen was procured with a dark band fol- 
lowing the order of the volutions. 
The habitat of this species, as given by Montagu, is clearly a 
wrong one, and must mislead those who search for it. He pro- 
bably found it creeping up the Iris pseudacorus, in consequence 
of its having been conveyed to such a situation by the waters of 
a flood.

In both the Glebe ponds near the Parsonage at Spexhall; in 
the pond at Offton, where Tellina stagnicola is found; and in a 
pond in Dynes's meadow, near Nettlestead Church.
