LAND AND FRESHWATER MOLLUSCA. 369 



C. laminata, Montagu. Not common ; in woods, generally on 

 or at the base of beech trees ; on beech trees on Wytham Hill ; at 

 the foot of oak and ash trees in Wick Copse. Mr. Whiteaves gives 

 Stow Wood and Stonesfield in his list. 



Cochlicopa tridens, Pulteney — Local and not very plentiful ; 

 found only amongst wet moss in groups of from six to ten 

 individuals in swampy parts of Wick Copse and Stow Wood, near 

 Headington. 



G. lubrica, Miiller.— Common and generally distributed. 



Achatina acicida, Miiller.— Dead shells of this species abundant 

 in the surface-soil near Wick Copse, Headington, South Hincksey 

 and other localities. 



Fam. IV. Carychiid^. 



Carychium minimum, Miiller.— Abundant everywhere in damp 

 places under stones, dead leaves, sticks and moss. 



Fam. V. CycLOSTOMATiDiE. 



Cyclostoma elegans, Miiller.— On hedge-banks and woods where 

 the soil is calcareous ; parts of Bagley Wood, at South Hincksey, 

 Wick Copse, near Headington, Horsepath, and also at Goring and 

 Streatley. 



Acme lineata, Drap.— After many searches for this rare species, 

 I discovered five specimens among moss growing on a clump of 

 Carex paniculata, by a stream running through the boggy swamp 

 at the foot of Wick Copse. 



This list contains ninety-three species, of which seven species, 

 viz., Sphcerium ovale, Limax Icevis, L. arborum, Testacella halio- 

 tidea, Zonites glaber, Z. purus, and Clausilia Rolphii, are not 

 mentioned at all in Mr. Whiteaves' list, and two others, viz., 

 Planorbis nautileus and Arion flavus, hitherto recorded only as 

 occurring near Banbury and at Watlington respectively, have 

 been found quite near Oxford. 



The following four species, which appear in Mr. Whiteaves' 

 list, need to be rediscovered before they can be permanently 

 retained in any catalogue of Oxford shells, viz. : — 



(1). Helix sericea.—A species which Mr. Whiteaves himself 



failed to find, and which he recorded solely on the authority of 



a Mr. Norman, who took it " in marshy ground at the foot 



of Bullingdon," about thirty years ago.
