var. alba Moquin-Tandon. — Neighbourhood of SaUsbury 

 (Jeffreys); Blunsdon (Cockerell); Great Bedvvyn (Townsend); Devizes 

 (Miss Cunnington); Mere and Edington (E.W.S.). 



Acanthinula aculeata (Miiller), — Rare. "In the woods at 

 Lackham " (Test. Brit., p. 430, as Helix spinulosd). Devizes (Miss 

 Cunnington) ; rare at Durnford, moist meadows amongst mossy 

 stones at Devizes (Vize); moist woods in Wiltshire (Jeffreys). 



Vallonia pulchella (Miiller). — Widely distributed. Montagu 

 wrote of it, " It is most commonly found in rivers and streams of 

 water, after floods, amongst the sand and other refuse brought down 

 by the current, having been swept from the neighbouring wet and 

 swampy situations. It is very plentifully found after a flood on the 

 banks of the River Avon, in North Wiltshire, about Lackham " (Test. 

 Brit., p. 441, as H. paludosa). Stourton, Mere and Edington 

 (E.W.S.) ; brickearth at Fisherton (Blackmore) ; Devizes (Hegin- 

 bothom); between Trowbridge and Studley, Salisbury, Devizes (Vize). 



Vallonia COStata (Miiller). — In all probability as widely dis- 

 tributed as the preceding species. Edington and Avebury, also near 

 Mere (E.W.S.) ; Hilperton Marsh (Vize); Swindon (Cockerell); 

 Devizes (Miss Cunnington and Heginbothom). 



Vallonia excentrica Sterki. — Probably hitherto confused with 

 F. pulchella. I found three specimens at Edington, in the Vale of 

 the White Horse. 



Helicigona lapicida (Linne). — Local. DaCosta recorded it in 

 177S as Cochlea acuta " from Wiltshire, in the moss on the bodies of 

 large trees, and in woods." Devizes, south of Kennet and Avon 

 Canal (Heginbothom) ; Marlborough, moderately common (Brome- 

 head); Corsham, Salisbury (Vize) ; Roundway Hill, Devizes (Miss 

 Cunnington); Edington (E.W.S.). 



Helicigona arbustorum (Linne). — "Widely distributed. DaCosta 

 recorded it from Wiltshire under the name of Cochlea unifasciaia. 

 Montagu wrote : " It delights in wet and shady places, particularly 

 amongst willows and alders where the soil is black and boggy. In 

 such places in the neighbourhood of Lackham in Wiltshire, contiguous 

 to the River Avon, it is the most common shell, but we have rarely 

 found it elsewhere" (Test. Brit., pp. 414, 415). A lightish form of 

 the type occurs in nettle beds on the banks of the Avon at Salisbury. 

 I have noticed in other places its fondness for nettles. A few 

 specimens in the drift at Milford Hill and in the brickearth at 

 Fisherton (Blackmore) ; Devizes (Miss Cunnington and others) ; 

 Idmiston (W. L. W^ Eyre); Marlborough, moderately common (Brome- 

 head) ; Hilperton, Bradford-on-Avon, Alderbury, Salisbury (Vize).
