354 HUDSON : MOLLUSCA OP SALOP. 



aspersa, and IT. rufescens being nearly everywhere abundant, 

 the latter species {H. rufescens) invariably among nettles (its 

 partiality for that shelter or food I have many times noticed). 

 H. ncjnoralis seemed to vary more in colour than in banding, 

 whilst of IT. hortensis I only took the type form, though two or 

 three hundred specimens came under my hands. H. aspersa 

 seemed chiefly to tend to var. tmdidata^ and many of the speci- 

 mens were very characteristic. The albine variety of H. 

 rufescens was, in Morda lane, even more abundant than the 

 type, and was general everywhere. The slugs are both abund- 

 ant and variable. The major portion of the Oswestry speci- 

 mens were obtained in a lane near St. Oswald's well. Elles- 

 mere, the largest sheet of water visited, was so agitated by a 

 sharp westerly wind that but little could be done, though it 

 promised to be a capital hunting locality. The canals were 

 generally too well dredged to repay an examination, though 

 such was made, and in one isolated backwater Paludina 

 vivipara, L. stagnalis, and Anodon turned up, the latter in eight 

 feet of water. 



The boles of the beech and other trees were examined for 

 Clausilia, Pupa, &c., but with little avail. Clausilia rugosa was 

 plentiful on most old walls, and one specimen of Balea perversa 

 occurred to me on the Llanforda road. Pupa umbilicata was 

 found once, but the only specimen shared the fate of a box of 

 Z. peregra from the moat at Whittington, and "is not." A 

 wood at Plas-yn-coed gave me a specimen of Limax cinereo- 

 niger, several Zomfes, and H. aculeata. Though certainly the 

 excessively hot weather had dried up the soil, I believe the 

 paucity of species, particularly of Pupa^ Zonites, and Vertigo, is 

 due to the careful 'cultivation of the land and the absence of 

 undergrowth in the coppices and woods. Btdbniis obscurus 

 was found all over ^Oswestry, principally on old walls and in 

 the hedgerows. Helix hispida is anything but common, and 

 H. rotundata, which I have got to look upon as " the ever 

 present," though found in most places, was by no means abund-
