HELIX, 121 



Inhabits shady places in woods and hedgerows and 

 damp spots by the side of rivers, among willows, 

 alders, &c. Although widely distributed over Great 

 Britain, this is a local species. It is lazy in its move- 

 ments and somewhat irritable. When crawling it 

 carries its shell in a slanting position. The epiphragm 

 is extremely thin.
