BALEA, Prideaux. 



Balea perversa, L. 



A common species and well distributed. 

 CLAUSILIA, Drap. 



Clausilia rugosa, Drap. 

 Abundant in all the eight districts. When 

 kept in confinement I have noticed that 

 they generally suspend themselves by means 

 of a short thread, about an inch in length, 

 which is attached to the sides of the jar or 

 box in which they are kept. 



Var. everetti, Miller. 

 6. Oxford. — "Plentiful with the type" (S. 

 Spencer Pearce, 1883). 



Var. gracilior, Jeff. 

 There is a single specimen in the Whiteaves 

 Collection. 



Var. tumidula, Jeff. 



6. Oxford.— IsHp (S. Spencer Pearce, 1883). 



Var. parvula, Turton. 



6. Oxford. — Near Stow Wood (Whiteaves, 



1857). 



Var. dubia, Drap. 



I. Banbury. — Common. 



3. Wychwood and Ciiarlbury. — Stonesfield. 



6. Oxford. — Common. 



Clausilia rolphii, Gray. 



This, perhaps the rarest species in Oxford- 

 shire, has only been found once. The Rev. 

 S. Spencer Pearce writes in his list of 1883 : 

 " I am able to record a new locality for this 

 species, which is more frequently found in 

 the Southern counties. While searching under 

 a hawthorn hedge near the village of South 

 Hincksty, in the early spring of 1880. I 

 came ui)on tirst one, and then several others 

 of this species. On comparing them with 

 Surrey specimens in my cabinet they proved 

 exactly similar in all points excepting colour, 

 the Berkshire specimens being of a darker 

 tawny brown. It must, I think, be put down 



as rare, as I have failed to find it again, 

 either in the locality just mentioned or in 

 any other in the vicinity."
