Z. excavatus Bean. — The non-calcareous district of Woodford provides 

 the only congenial habitat for this calcifuge species in the vice- 

 county. It is plentiful in the old woods of that locality associated 

 with Limax cinereo-niger, A canthinula lamellata, and Hy. nitidula var. 

 helmi. The typical dark form seems to be quite absent, all the 

 specimens seen by me being var. vitrina. 



Euconulus fulvus Miill. — Widely distributed, but not common, except in 

 the decaying rejectamenta of lakes and rivers. Var. alderi occurs 

 by Lough Derg near Portumna. 



Arion ater L. — Common throughout the district. Vars. castanea and 

 plumbea are frequent. Var. succinea is plentiful in the Woodford 

 woods, and var. bicolor has been found near Portumna and Woodford. 



A. subfuscus Drap. — Widely distributed, but not common. Vars. rufo- 

 fiisca, cinereo-fusca and fuliginea were all taken in woods at Woodford. 



A. intermedius Normand. — Generally distributed. Seen in woods at 

 Woodford, Coole, and Dalystown ; on the shores of L. Cutra and L. 

 Derg ; under old coffin-boards at Kilmacduagh ; also at Ballinasloe, 

 Portumna,. and Oranmore. Yellowish-grey is the most prevalent 

 colour form. 



A. hortensis Fer. — Common throughout. Abundant in gardens and by 

 walls near towns and villages. Frequent in woods, as at Woodford, 

 Dalystown, Portumna, and Lough Cutra, and by the sea at Oranmore 

 and Aughinish. The usual colour form is black, but grey and brown 

 specimens are frequent. Native in the woods and by the sea, perhaps 

 introduced in some of its other habitats. 



A. circumscriptus Johnston. — Generally distributed. Seen in nearly every 

 locality visited, but always in small numbers. 



Punctum pygmaeum Drap. — In woods at Woodford, Portumna, Coole, 

 Lough Cutra, Castle Taylor, and Kilcolgan. Under stones and logs 

 on the shores of L. Derg. Very numerous in flood debris at Coole. 



Sphyradium edentulum Drap. — Frequent in woods throughout, also in 

 marshy places near most of the lakes. Var. columella Jeffreys occurs 

 under stones by Lough Rea, on a wall near Portumna with Ena obscura 

 and Vertigo pusilla and in a wood at Castle Taylor. This form is not 

 5. columella von Martens. 



Pyramidula rupestris Drap. — Exceedingly abundant on rocks and walls 

 throughout the limestone area. Sparingly on limestone boulders 

 in a small isolated deposit of boulder-clay about a mile west of Wood- 

 ford. 



P. rotundata Miill. — Common everywhere. Varies in height of spire, 

 vars. turtoni and pyramidalis both being represented. In old woods 

 at Woodford, Portumna, and Coole ; also by the sea at Aughinish 

 and Kinvarra, greenish -white and fawn unicolours are common. 



Helicella Virgata Da Costa. — Widely distributed but, except along the coast, 

 not general. Abundant where it occurs at Aughinish, Kinvarra, 

 Kilcolgan, Oranmore, also inland at Gort, Ardrahan, Athenry, Ballina- 

 sloe, Portumna, and Loughrea. Banded forms and var. lutescens are 

 common. Vars. submaritima, albida, alba, and hyalozonata are
