178 The Irish Nalunilisl. September, 



reached the old woods of Cratlagh, which fringe the western 

 shores of Mtilro}' V>3.y. We were, however, partly able to 

 gratify otir expectations b}' finding a few specimens of 

 Hyali)iia cxcavata, but although searched for keenly, Limax 

 cincreo-nigcr was not found. We had rather expected to turn up 

 this beautiful slug, as Mr J. N. Milne has taken it in similar 

 woods at Ray in a neighbouring parish. Besides Hyalinia 

 excavafa,the other members of the Zoiiitidse seen were Hyalijiia 

 ccllaria {Vitrca hibcrnica^ Kennard), //". alliaria, H. nitidula^ 

 H. pu?a, H. crystallhia and H. fulva. Specimens of the last 

 species taken on the uplands above the wooded area were 

 particularly large and rather pale in colour. Slugs of the 

 genus Arion were especially common, all five species being 

 taken. The Helices were poorly represented, H. roiundata 

 and H. nevioralis being the only two to figure on the day's list. 

 No doubt a further search would also produce Helix pygmcea, 

 H. aculeata, H. larnellata and H. fusca. The onl}' other 

 land-shells seen in this locality were : — Vitrina pellucida^ 

 Agriolimax agresiis, Cochlicopa lubrica^ Carychium minivium. 

 Pupa cyli7idyacea, P. anglica var. pallida^ Balea pe7'versa, and 

 Clausilia bideiitata. 



With the exception of the Pisidia, kindly identified by Mr. 

 B. B. Woodward, F.I^.S., whose names we have adopted for 

 this genus, the nomenclature is that given by Dr. Scharfif ^ in 

 his " Irish I^and and Freshwater Mollusca."
