The result of six hours' collecting in Sligo, Easter, 1906. —Having only 

 three days at my disposition, and wishing to see most of the ground covered by the 

 Irish NaturaHsts at the Sligo Conference of September, 1904, that is to say 

 Glencar, Lough Gill, Dromahair, Knocknarea, Strandhill, etc., I took note of the 

 actual time given up to shell hunting with the following results. As the localities 

 are given by Messrs. Welch and Stelfox and as I got nothing outside their list, and 

 did not cover the whole of it, I just give the names of species collected : 

 Vitrina pellucida Miill., Hyalinia cellaria Miill. , H. alliaria Miller, H. nitidula 

 Drap., H. piira Alder, H. radiatula Alder, H, crysiallina Miill., H. ftilva 

 Miill. ,^. nifida Miill., Avion ater L., A. subfusais Drap., A. hortensis F6r. , 

 A. ciraimscriptus Johnst., Agriolimax agrestis L. , A. Icevis Miill., Amalia 

 sowerbyi Fer. , Helix pygtncea Drap., H. rotundata Miill., H. riipestris Drap., 

 H. pulchella Miill., H. excentrica Sterki, H. aculeata Miill., H. lamellata Jeft"., 

 H. hispida L., H. rttfescens Penn., H. fusca Mont., H. arbustortim L. , 

 H. acuta Miill., H. nei/ioralis L. , H. aspersa Miill., Cocklicopa lubrica Miill., 

 Pupa anglicaYkx., P. cylindracea DaCosta, P. vmscorum Miill., Vertigo edentula 

 Drap., V. pygm(eaY)x2.-^., V. subslriata ]e^., V. aiigustior]&ii., Baleaperveisa'L., 

 Clausilia bidentata Strom, Succinea putris L., 5^. elegans Risso, Carychiuvi mini-

 Miill., Physa fontinalis L. , Planorbis contort us L. , Ancylus Jluviatilis Miill., 

 A. lacustris L. , Acme lineata Drap., Bythinia tentaculata L., Hydrobia ulvte Penn., 

 Valvala piscinalis Miill. , V. cristata Miill. , Neritina Jluviatilis L. , Pisidium sub- 

 truncatum Malm, P. gassiesiantiin Dup. , P. pusillum Gmel. I fall short by 

 thirteen of the Sligo conference list, but nevertheless, considering the dryness 

 of the weather, and early season, .Sligo can well be called a conchologists' paradise. 

 All these shells, except slugs, were shown at the Conchological Meeting of 

 May 9th, and confirmed by Messrs. Standen & Oldham. — B. R. Lucas (Read 

 before the Society, Dec. nth, 1907).
