1904. Welch & Sr^i^^ox.— S/igo Co?2/ere?ice, Molhisca. 187 



LImax maxlmus, L. — Not a trace of this species anywhere during 

 the week's visit During our 1900 visit the var. Fe7-ussaci was found 

 at Glencar. 



L. marginatus, Miill. — A few in Knocknarea Glen, and in the 

 Glencar woods near the fall. This was about the only species that 

 the heavy shower brought out on the crawl at Rockwood, We got 

 some then in the Slish woods. 



Agriolimax agrestlSi Iv, — Common inmost damp places; larger in 

 Glencar and at the cave in Gleniif than elsewhere ; Dromahaire 

 Abbey, Ballysadare old church, and var. iti^ra on Inishmurry, 1900. 



A. laevls, Miill. — As usual not common; along stream sides, Rosses 

 Point ; Raghly ; Ivissadill Glen ; lake shores of Lough Gill at Rock- 

 wood and Glencar Lake ; Dromahaire, 1900. Where Hyalmia nitida 

 occurs, this species will usually be found not far off, and both are 

 sometimes 'associated with Vertigo antivej-ligo and a small, deep-red 

 form of Siiccinea elegans in the marshes of north-east Ireland. At 

 Rosses Point it was with the first named. 



Amalia Sowerbyi, Fer. — One or two only in Slish Wood, but in 1900 

 we found a number inside the cashel on Inishmurry. 



Helix pygmaea, Drap. — Very rare at Rockwood, a few in the Strand- 

 hill shell pockets, one in Glencar. In moss at Glencar (Co. Sligo), 

 1900. 



H. rotundata, Miill. — At all the localities visited, but not so common 

 as on Inishmurry and in the district south of Sligo in 1900. 



H. rupcstris, Drap. — Generally distributed on the limestone; abun- 

 dant on some dr}' stone dykes at Rosses Point, Raghly, Carrowmore, 

 Lissadill, Glencar, and Swiss Valley. On cliffs at the cave at GlenifiF; 

 in profusion at Dromahaire Abbey, living with Balea perversa among 

 the flat stones on summit of dyke, 1900. 



H. pulchella, Miill. — A few under stones at Rosses Point, and in abund- 

 ance dead in shell-pockets at Strandhill ; var. costata on shore at 

 Glen Lodge, Knocknarea, and some nice specimens with the type, in 

 an exceedingly dry situation under stones on the short turf along 

 the strand at Raghl3\ Only inland locality, Glencar, 1900. We have 

 never taken the variety except in a very dry situation, though the 

 type may be found also on lake shores and in marshes, locally, all 

 over the central plain. L. E. Adams states {Mamial, 1896, p. 57) that 

 in Scotland it is more plentiful on the east coast than on the west. 

 In Ireland the reverse holds good. 



H. aculeata, Miill. — A few in moss, Lissadill Glen ; near Doonee Rock ; 

 in shell-pockets, Strandhill ; with var. albida, Glencar woods, Glencar 

 (Sligo), 1900. 



H, laiYiellata, Jeff. — Very local, only in old native woods as usual. 

 Adams states {pp. «/.)that " It is one of those few species of which no 

 one has been ingenious enough to find varieties." Among mossy 

 stones and dead leaves, under Doonee Rock we found a few colour- 

 less specimens with the typical form. A few near Glencar fall, 1900.
