Proceedingsof the Royal Irish Academy 56B: 29-133NoteSince this talk was given, recent fieldworkhas now extended the distribution of Osilinuslineatus. A single specimen was found in theNW of Strangford Lough at Darragh Causewayin April 2004. It has also now been found atthree sites on the outer Ards Peninsula, themost northerly being Slane’s Point in July 2004(four specimens). Visits to sites further norththan Slanes Point have not yet yielded anyrecords of this species.The Status, Distributionand Ecology of Paludinellalittorina (delle Chiaje,1828) (Gastropoda:Assimineidae) in theBritish Isles.Ian J. Killeen and Janice M. Light.For the full paper, readers should refer to:Journal of Conchology, vol 37, no.5 pp 551-563.AbstractSurveys over the last 15 years haverevealed that the assimineid Paludinellalittorina (delle Chiaje, 1828) is much commonerin the British Isles than previously believed.It is currently known living at 40 sites rangingfrom the Isles of Scilly, eastwards along theChannel coast of England as far as the easternend of the Isle of Wight. It extends as farnorth as the Bristol Channel with sites on thenorth coast of Devon and the coast ofPembrokeshire. The west coast of the Lizardpeninsula, Cornwall and the Isles of Scillysupport significant numbers of P. littorinapopulations. The two principal habitats inwhich we have found P. littorina are caves,and shores with a supra-littoral zonecomprising large stones and boulders withstable interstitial gravels beneath.Observations on the species’ habitats, ecologyand conservation are discussed.36PMNHS Newsletter No.16 Nov 2004Porcupine Marine Natural History Society (www.pmnhs.co.uk) newsletter archive
