having a single dark band encircling it. The aperture 

 is roundish-lunate, the peristome being milky-white in 

 colour and reflexed. The shell is moderately thick, and 

 polished. Spire somewhat elevated. It has six convo- 

 lutions. The umbilicus scarcely discernible. 



About three-quarters of an inch is the usual diameter. 

 The diameter of specimens procured near Thrumpton is 

 ten lines ; height three-quarters of an inch. Specimens 

 from this locality are very rich in colour and marbling, 

 and the band is very dark. Those from Weymouth are 

 three-quarters of an inch in diameter, and five-eighths 

 of an inch high. 

 The animal is dark in colour, being leaden-black. 

 It is longer, but narrower than Helix nemoralis. 

 A variety with a pale straw-coloured shell, marbled 

 with white, and destitute of the dark band, has been 

 forwarded by Mr. W. K. Bridgman, as being found not 

 uncommonly near Norwich. And an intermediate 

 variety between this and the ordinary typical form has 

 been sent by Mr. R. Damon, as procured near 

 Weymouth. 



An inhabitant of moist woods, and near water, 

 amongst willows, nettles, moss, and couch-grass. 

 Described by Dr. Lister, in the year 1678. 

 Professor Forbes remarks that it extends to a higher 

 elevation on mountains than any other of our large 

 Helices, and although the specimens are small as found 

 on the Swiss Alps, yel is is observed almost to the 

 limit of eternal snow. 



.Notwithstanding it is a widely-spread species, it is 

 not very abundant, and rather local. 



In this neighbourhood it has been found, amongst 

 nettles and coarse grass, near the River Soar, at 

 Tbrumpton; and near the Trent, at Sawley. In 

 neither of these places is it abundant.
