176 LAND AND FRESH-WATKR MOILUSKS. 



Helix fusca. — Dead but very fine specimens in Witcomb wood and at Long- 

 ford, near Minching Hampton. 



Helix fulva. — Amongst damp leaves: not infrequent. 



Helix aculeata. — Occasionally met witli in company with the former. 



Helix granulata. — In springy spots in the- valleys round Stroud and Minching 

 Hampton. 



Helix hispida. — To be found in any quantities at Brimpsficld Castle, near 

 Birdlip; and tolerably numerous in other localities. 



Helix concinna. — Generally diffused. 



Helix rufescens. — Of every size and shade of colour, and in every variety 

 of locality. 



Helix virgata. — Very numerous on the short grass of the downs, but most 

 commonly small, though well marked. 



Helix caperata. — Not unfrequent, but rather local. 



Helix ericetorum. — Very numerous with virgata; exceedingly variable in 

 size: a few specimens of the variety ohlitemta. 



Zonites rotundatus, — Common: one very fine specimen of the crystalline 

 variety ; I may mention that I had previously found this variety at Kenil- 

 "worth Castle, and at Upton, near Birkenhead. 



Zonites umbilicatus. — In myriads under the small loose stones of the dry 

 stone walls in elevated districts; I have traced them for twenty miles on 

 what may be almost called an unbroken chain of wall, and they appear to 

 extend across the country in every direction. 



Zonites pygmaeus. — On dead and damp leaves at Birdlip, etc. 



Zonites alliarius. — An occasional specimen under a stone or in moss. 



Zonites cellarius. — Common and fine. 



Zonites purus. — Very fine specimens amongst damp leaves at Birdlip, Down 

 Wood, etc. 



Zonites nitidulus. — Some very fine specimens. 



Zonites radiatulus. — Rather scarce. 



Zonites lucidus. — On the brink of the canal at Chalford: a few specimens. 



Zonites crystallinus. — Very common amongst damp moss and leaves. 



Succinea putris. — Common. 



Succinea Pfeifferi. — Common. 



Bulimus Lackmanensis. — On the stems of beech trees at Birdlip, Cooper's 

 Hill, Lineover, and Chalford during summer; in winter amongst the dead leaves 

 and moss at their roots. As far as I am yet able to judge, this fine 

 Bulimus appears to be confined to the chalk and limestone formations. 



Bulimus obscurus. — Common on rocks and beech trees. 



Zua lubrica. — Tolerably frequent in damp spots. 



Azeca tridens. — Local but not unfrequent. They appear to congregate in 

 little family parties, for if you find one, you may be pretty sure of finding 

 half a dozen others within a few inches. 



Achatina acicula. — One dead specimen on Minching Hampton Common.
