be the only locality for H. ericetormn in Bute, but I have received 

 specimens also from Machrihanish Bay, Campbelton. The occur- 

 rence of H. rufescens at Bowling has already been brought before 

 this Society. At Broomfields, Largs, in a grassy lane, I discovered 

 a colony this summer. Most of the specimens were albinoes. A 

 single specimen was taken at Etterick Bay, Bute. H. hispida and 

 //. rotandata are common everywhere. H. aculeata and H. lamel- 

 lata are found in company in wooded glens, Woodend, and 

 Mount Stuart, Bute. On the broad leaves of Petasites vulgaris in 

 Brisbane Glen, Largs, two species may be taken— iiT. sericea and 

 H. fusca. The latter I have also found at Mount Stuart and 

 at Ardbeg, Bute. 



Not a single representative of the genus Bulimus occurs in Bute, 

 but at Machrihanish Bay, Campbelton, B. acufiis has been dis- 

 covered by Mr Dougal. Zua lubrica is a common shell every- 

 where. 



Of the Genus pupa, three species inhabit the district which we 

 have in consideration. The most common, P. umbilicata, is to be 

 found plentifully under stones and among moss in almost every 

 situation. No shell occurs in such numbers along the coast as 

 this. Along the east shore of the island especially, thousands 

 may be gathered in a short time, every stone, on its under side, 

 being literally covered with them. P. muscorum seems to be a 

 much scarcer shell. In Bute I have not been able to find a single 

 specimen, but on the other side of the Clyde, at Fairlie, it dwells 

 in company with P. umbilicata on the shore. The remaining 

 species, P. anglica, I have taken in Mount Stuart woods on the 

 fallen leaves of the laurel, and in Brisbane Glen, Largs, amongst 

 the debris of a ruin, along with Helix sericea. 



The genus next in order. Vertigo, is unrepresented in the 

 Glasgow district. In Bute two species occur, V. edentula and 

 V. antivertigo. The former may readily be found on examining 

 the under side of the fronds of Lastrea filix mas — Skeoch Wood 

 and Chapelton — and also under stones on the banks of Loch 

 Greenan. The latter occurs on the banks of Loch Ascog and 

 Loch Greenan. V. pygmcea, although said to be the most widely 

 distributed of the genus, is the scarcest in this district. Often 

 have I sought for it on elevated situations, such as it is said to 

 inhabit, but without success, till this autumn, Avhen wandering 

 along the seashore at Largs, at Broomcraigs, I came upon the
