368 THE ZOOLOGIST. 



are North and South Hinckseys, Islip, Woodeaton, Headington, 

 Garsington, and Sandford, near Fyfield. 



Vertigo pygmaa, Drap. — Rather frequent and generally dif- 

 fused. It does not seem to show any preference for elevated 

 situations, as Mr. Whiteaves has inferred from the localities he 

 gives, viz., Headington Quarry, Bagley Wood, and near Stow 

 Wood ; for I have taken it under stones by brook near South 

 Hincksey, together with V. ede7itula, and moreover it would be 

 difficult to explain the fact that this shell is found in such 

 numbers in the river alluvium washed down during flood-time, 

 unless it inhabited the low-lying lands near the river. 



V.pusilla, Mliller. — Very local ; it is still to be found in plenty 

 on the ivied wall near Woodeaton, as recorded by Mr. Whiteaves. 

 V. edentula, Drap. — Rare; amongst dead leaves and moss, 

 and under stones in woods, copses, and marshy places ; by stream 

 near South Hincksey, copse near Childsworth Farm, near Sun- 

 ningwell, and " in a marshy hollow near Stow Wood," according 

 to Mr. Whiteaves. 



Balca perversa, Linn. — Common on old walls and trees, 

 especially pollards. 



Clausilia nigricans, Pulteney. — Abundant and generally dis- 

 tributed. 



Var. Everetti. — Found plentifully with the type. 

 Var. dubia. — A few specimens of ventricose form and of larger 

 size from Wytham Hill I take to belong to this variety. It also 

 appears in the Whiteaves collection. 



Var. gracilior. — A single individual of this variety is in the 

 Whiteaves collection. 



Var. tumidula. —At Islip. I have also a small wrinkled variety 

 from loose iron-stone walls near Wheatley. 



C. Rolpkii, Gray. — 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 

 Hincksey, in the early spring of 1880, I came upon, first 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.
