LAND AND FRESH-WATER MOLLUSKS, 177 



Pupa umbilicata. — By no means numerous. 



Pupa marginata, — Generally diffused in small numbers amongst short grass 

 on the downs; but at Minching Hampton on the top of walls in Sedum acre. 

 in company with II. costata in the greatest profusion, and most specimens 

 very fine. 



Pupa Juniperi. — Very abundant at the foot of walls and under stones; one 

 crystalline specimen, but smaller than the usual variety. 

 Vertigo edentula. — A few specimens under leaves generally in damp and 

 boggy situations. 



Vertigo pygmaea, — Amongst the short grass on the Common at Minching 

 •Hampton, etc. 



Vertigo palustris. — In a damp spot on the same common. 

 Bala3a perversa. — Not uncommon on trunks of trees and old walls. 

 Clausilia bidens. — Very numerous and fine on the stems of beech trees, 

 in hedge-rows, etc. I found several specimens of a beautiful hyaline variety 

 at Cooper's Hill and Cranham Wood, adjoining. 



Clausilia Rolphii. — Several colonies of this very local and rather scarce 

 clausilia, extending from Birdlip to Cooper's Hill. This appears to mc a 

 completely new locality, never having heard of its being found so far north 

 before ; the principal number I found amongst patches of Saxifraga oppositi- 

 folia, in company with Axeca tridens, and not unfrequently six or eight in a 

 cluster at the roots of a tuft of grass growing amongst the Saxifraga, which 

 was in a damp situation ; but it must be borne in mind, that they were 

 still enjoying their winter sleep; perhaps when the weather became more 

 genial, they might be more scattered. 



Clausilia nigricans. — Also its variety, very common. 



Carychium minimum. — Numerous. 



Acme fusca. — One dead specimen at Birdlip. 



Limnaeus auricularis. — Common and rather fine in canal at Chalford. 



Limnaius pereger. — Several varieties in canal and in neighbouring ditches. 



Limnaeus stagnalis. — A few specimens in same canal, 



Limnaeus palustris. — A few specimens in same canal. 



Limnaeus truncatulus. — A few specimens in same canal, and in ditches. 



Ancylus fluviatilis. — A few on stones and shells, at Chalford. 



Physa fontinalis. — One or two fine specimens at Chalford. 



Planorbis corneus. — Numerous in some of the reaches of the same canal. 



Planorbis albus. — A few in same place. 



Planorbis carinatus. — A few in same place. 



Planorbis marginatus. — A few in same place. 



Planorbis vortex. — In ditches near Cheltenham. 



Planorbis spirorbis. — In ditches near Cheltenham. 



Planorbis contortus. — Canal at Chalford.
