SWANTON ! LAND AND FRESHWATER MOLLUSCA OF SOMERSETSHIRE. 195 



Var. fusco-labiata V. Marts. — Well distributed. 



Var. lurida Moq. — With the bands half-effaced. Frequent at 

 Bratton St. Maur. 



Var. arenicola Macgill. — Very common. I have paid great 

 attention to the banding of this species within a comparatively small 

 area, viz., Bratton St. Maur and surrounding villages, bounded by 

 the towns of Wincanton, Bruton, and Castle Cary, and have secured 

 the following variations (Von Martens' band formula) : — ■ 



00000 1 (i2345) °°3(45) 



00005 00300 (123X45) 



00045 IOO °5 I ( 2 3)(45) 



10345 10045 1(234)5 



12345 02345 123(45) 



100(45) 000(45) 



It has been recorded that the absence of the third or peripheral band, 



or its presence only (as seen so commonly in H. nemoralis) is of rare 



occurrence in H. hortensis ; yet of the twenty-four possible band 



variations in which the peripheral band is absent (including the 



totally bandless form, so called variety unicolor), we have secured 



eight in our district. Cockerell 2 has given a list of all the then 



known band variations of H. nemoralis and H. hortensis, to those of 



the latter I may add 02345, 000(45), IOO (45)> °°3(45)> (already 



given above and not recorded in his list). B.F. 00300 is decidedly 



rare, I have only 2 or 3 examples. 



Helix arbustorum L. — " Frequent, though local. I have 

 taken it in the lane leading from Clevedon to Clapton ; under heaps of 

 stones on Strawberry Hill, Clevedon ; upon the banks of the canal at 

 Bath ; among nettles at Cheddar Cliffs ; and hedge-banks near 

 Axbridge " (Norman). To the above localities we may add Dundry 

 and Leigh Woods, Bristol (examples in the Wilson Collection, Bristol 

 Mus.) ; near Taunton (Bowel!) ; hedge-banks on the lower slopes 

 of Castle Cary Hill (Macmillan) ; West Pennard, Glastonbury ; also at 

 Pitcombe, Milton Clevedon, and many other places in and around 

 Bruton. 



Var. major. — Leigh Woods, Bristol (Bristol Mus.). 



Var. fuscescens D & M. — Bath ) Milton Hill, near Bruton ; 

 hedge-banks at Castle Cary. 



Var. albina Moq. — Bath (Bristol Mus.). 



Var. conoidea West. — Leigh Woods, Bristol (Bristol Mus.) ; 

 hedge-banks at Milton Clevedon ; and the lower slopes of Creech 

 Hill, towards Bruton.
