 Lister Couch, t. 1 24. f. 24. 

 Inhabits marshes and about ponds and ditches, and appears .to 



be common in most parts of Europe. 

 Shell three-quarters of an inch or an inch long, and about one- 

 third as broad, brown, sub-pellucid, generally covered with a 

 dark epidermis ; it has six whirls, which taper to a fine point, 

 and are obsoletely marked with both longitudinal and trans- 

 verse strias ; it is stronger in its texture, and has the body- 

 whirl much less distended than H. stagnalis, and Schroeter's 

 figure of H.fragilis differs in having the aperture much 

 more oblong. Schroeter considered his t. 7- f. 7. to be a 

 variety of the present species, and Schreibers has placed it 

 separately ; but this part of Schreibers' work is so badly ex- 

 ecuted, as not to be worth notice. Schroeter, in the Fltiss- 

 conchylietiy p. 319- t. 7. f. 14, has described and figured a 

 minute species, one line and a quarter long, and has quoted 

 the Nerita minuta of MuUer's Verm. ii. p. 179' It has 

 been kept separate in the Eiuleitung (Helix, No. 254), but 

 is not noticed by Gmelin or any other author, and is pro- 

 bably the young of some neighbouring species.

 Inhabits muddy ditches, drains, and water-courses, and is more 

 often found at the edge of the water than in it ; not uncom- 

 mon in England. Montagu. 

 Shell about three-eighths of an inch long, and somewhat less 

 than half as broad, rather thin, sub-pellucid, and horn- 

 coloured ; it has much the habit of H. palmtris, but is not
