SWANTON : LAND AND FRESHWATER MOLLUSCA OF SOMERSETSHIRE. I99 



Monstr. sinistrorsum Taylor. — Sea wall near Clevedon (Norman) 

 Helix acuta Miiller. — Confined exclusively to the sand-hills of 

 the coast, especially abundant in the neighbourhood of Burnham. 

 I might draw attention to an extremely doubtful locality for it, given 

 in CundalPs list, where it is recorded for "Leigh Woods and the Downs, 

 Bristol." Norman records it for Burnham and Weston; the examples 

 in the Bristol Museum are from the former locality, where I have 

 very frequently taken var. strigata Menke. 



Buliminus montanus Drap. — Apparently confined to the 

 Mendips, and Bristol and Bath districts. "Though nowhere to be 

 met with in any numbers Bulimus Iackha?nensis is widely distributed 

 throughout Somersetshire" (Norman); Neighbourhood of Bristol 

 (Miller, Jeffr.) ; Beachen Cliff and woods on Claverton Down, Bath 

 (Clark, Mrs. Oldroyd); and there are examples in the Jenyns collection 

 (Bath Mus.) ; near Cheddar (Rev. W. H. Hawker); " Hedgebank 

 on road between Axbridge and Cheddar, three-quarters-of-a-mile from 

 the former " (Norman) ; Milton, Clevedon Hill, two miles from 

 Bruton ; common. Frequenting the decaying fronds of Scolopendrhim 

 vulgare in summer ; in the late autumn I have found it concealed 

 in the hollow dried stalks of various umbelliferous plants (E.W.S.). 



Buliminus obscurus Miiller. — A common species. Examples 

 in Jenyns coll. (Bath Mus.), and Wilson coll. (Bristol Mus.). 



Var. albina Moq. — Coombe Down, Bath (Mrs. Oldroyd). 

 Abbott's Leigh (Bristol Mus.). 



Pupa secale Drap. — A local species, and, like B. montanus, con- 

 fined to the northern half of the county. Coombe Down, Bath (Mrs. 

 Oldroyd) ; Examples in the Jenyns coll. (Bath Mus.) ; Leigh Woods, 

 Bristol (Cundall) ; " Abundant amongst limestone rocks, Wrington, 

 Yatton, Clevedon, Wells, and Cheddar" (Norman). 



Pupa cylindracea DaCosta. — A common species. Jenyns coll.

Var. edentula Moq. — Bratton St. Maur ; rare (E.W.S.) ; Near 

 Tickenham (Norman).

 Mill above Wincanton (E.W.S. ). 



Var. gracilis Issel (?) — "A fine produced variety occurs among 

 the ruins of Walton Castle " (Norman). 



Pupa muscorum L. — A local species. Leigh Woods, Bristol

 (Mrs. Oldroyd) ; Rejectamenta of the Brue at Castle Cary, and of 

 the stream at Shepton Montague (E.W.S.).
