THE CONCHOLOGIST. 



1. Banbury. — Broughton and Little Bourton. 



2. Chipping Norton. — Uncommon. 



3. Wychwood and Charlbury. — Charlbury 



on Great Oolite (Pidgeon, 1875). Stones- 

 field. Abundant on nettles (O. V. 

 Aplin, 1882). 



4. Deddington. ^Common near Deddington, 



1888. 



6. Oxford. — ■" Abundant but local ; Head- 



ington and Shotover Hill" (Norman, 

 1853). "Very local, Headington, 

 Cheney Lane and on Cowley Marsh " 

 (Whiteaves, 1857). Recorded from 

 numerous localities in Pearce's 1883 

 list. 



7. Svvincomb. — Abundant. 



Helix rufescens, Penn. 

 A common and well distributed species, 

 occurring in large numbers in all the districts. 



Var. alba, Moq. 

 6. Oxford.— " Li Worcester College Gardens " 

 (Dalton, 1S55). " Rather scarce " 

 ■ (Whiteaves, 1857). "Common" (S. 

 Spencer Pearce, 1883). 



Var. depressa, Loc. 

 I. Banbury. — "On an old wall outside the 

 village of Adderbury, near Banbury 

 (S. Spencer Pearce, 1883). 



Helix hispida, L. 



Common throughout the county. 



Var. depilata, Alder. 

 6. Oxford. — "Near Wytham " (Whiteaves, 

 1857)- 



Var. albida, Jeff. 

 3. Wychwood and Charlbury. — Under stones 

 at Stonesfield (S. Spencer Pearce, 1883). 

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



Var. concinna, Jeff. 

 As common as the type in all districts. 



Var. minor, Jeff. 

 Occurs plentifully in districts 3, 6 and 7. 



Helix granulata, Alder. 

 = sericea, Auctt. 

 This species is recorded by Whiteaves 

 (1857) from marshy ground at the foot of 

 Ballingdon. Since then it does not seem to 

 have fallen to the lot of any collector, and 

 I was almost of opinion that it was extinct 

 in the county, until I found three specimens 

 at Little Bourton, in district 1, last year (1890). 

 There is no doubt but that this species is rare 

 in Oxfordshire, but I think if carefully sought 

 for it will be found in other localities. 



Helix fusca, Mont. 

 Rare, and confined to the northern district. 



1. Banbury. — Broughton, 1887. 



2. Chipping Norton. — Near Chipping Norton, 



1887. 

 4. Deddington — This record is doubtful. 

 I have three specimens labelled H. 

 fusca, 1888, which, I think, were col- 

 lected near Deddington. 



Helix pisana, Mull. 

 It is with some amount of diffidence that 

 I include this species amongst the mollusca 

 of Oxfordshire. Its only claim lies on the 

 occurrence of a single specimen, which was 

 found near Charlbury in 1887. Until other 

 occurrences are recorded I can only look 

 upon it as introduced. 



Helix virgata, DaCosta. 

 A common and well distributed form. On 

 the limestone the shells are much larger and 

 stronger. It is very common on the lime 

 stone in the w^est of the county, Mr. O. V. 

 Aplin informs me. 



Helix caperata, Montagu. 

 A somewhat local form and not common.
