Shell about half the size of the last, with about five 

 volutions, of a greenish hyaline colour, with regular 

 transverse striae, sometimes brownish horn-colour ; 

 sometimes a little wrinkled or striate at the sutures 

 only. 



From all the varieties of the H. miens it may be dis- 

 tinguished, by the want of the whiteness under- 

 neath ; the aperture is also more rounded, and the 

 outer volution comparatively larger : the animal is 

 black-grey, growing paler in the more lucid 

 varieties. 



A variety, perhaps a distinct species, has been sent 

 to us by Mr. Alder under the name of H. exavata 

 with the following remarks. When full-grown it 

 has one whorl more, they are consequently more 

 closely set, and the outer one is smaller in propor- 

 tion : it is more strongly striate, more convex on 

 both sides, and the umbilicus is much larger. The 

 animal is paler, and it is always found under de- 

 cayed wood, in more elevated spots, and not in 

 ditches and marshes, like H. lucida. 



41. HELIX hispida. Shell slightly convex, a little 

 carinate, striolate, transparent, horn-colour, hairy : 

 umbilicus moderate.
