JACKSON : NOTES ON SHROPSHIRE MOLLUSCA. 47 



Quarry in Wenlock limestone near Much Wenlock : — Agiioiunax 

 Liii^-estis, Vitrina pellucid<i, Vitrea cellaria, V. alliaria, V. nilidula, 

 Arioii hortensis, Pyramidiila rotundata, Helicella itaia, H. caperata 

 and var. ornaia, Hygro/iiia Itispida, Helix nemoralis, Eiia obscnra, 

 and Claiisilia hideutata var. parnila, amongst stones and scanty 

 vegetation. 



Ancyhis flicviatilis and Anodonta cygncea were noticed in Belswar- 

 dine Brook, Shineton ; and Helix hortensis vars. and H. cantiana 

 were very common on hedge-banks from Buildwas, through Farley, 

 to Much Wenlock (Wenlock shales and limestone) Dr. J. Cosmo 

 Melvill was the first to record H. cantiana for this neighbourhood 

 (y. of Conch., 12, p. 295). 



At Ludlow — Lower Old Red sandstone — Agriolimax agrestis, 

 Vitrea cellaria, Arion ater var. castanea and var. succifiea, A. circiim- 

 scriptus, Hygromia liispida, Helix aspersa, H. netnoralis, and H. 

 hortensis, were common among refuse in a sandpit. 



Agriolimax agrestis and Vitrina pelliicida were also common under 

 stones at Ludlow Castle. 



Bridges near Ratlinghope — purple slate of Upper Longmyndian: — 

 Vitrina pellucida, Vitrea alliaria, and Hygromia hispida, common 

 under slabs of slate. 



Whilst in the district, I visited Shrewsbury Museum, and on look- 

 ing over the magnificent series of Roman remains from Uriconium I 

 noticed a bowl full of Helix aspersa, labelled '^H pomatia.^' This 

 has no doubt been rectified by now, but I mention it here in case the 

 species has been recorded as H. pomatia. Errors of this kind have 

 unfortunate powers of vitality. Note (added Jan., 1910).—! find to 

 my great regret that I am, unfortunately, too late to prevent the 

 above wrong identification from being placed on record, as on refer- 

 ring to 'The Roman Fort at Manchester, 1909,' p. 68 (footnote) I 



notice the following remark : — " specimens of Helix 



pomatia were found at Wroxeter and are preserved in the Shrewsbury 

 Museum." From the few observations I was able to make, I cer- 

 tainly think the district of South Shropshire shows promise of yielding 

 a fairly large list of species if systematically worked. 



Paludestrina jenkinsi in the New River.— I recently found this species 

 in the New River at Pahner's Green (Middlesex), where both the type and var. , 

 carinata are very plentiful ; in fact, it is certainly the commonest mollusc in that 

 portion of the New River. I have also met with it in the New River at Ches- 

 hunt (Herts.). — Geo. H. Weaver {Read before the Society, Nov. loth, 1909).
