 Bulimus peregrus. Bruguiere Enc. Meth. p. 301. 



Inhabits the garden at Fredericksburg; and is amphibious. 

 Midler. In the Seine, and about the banks of rivers near 

 Paris. Bruguiere. 



It is the more difficult to ascertain this species, because MuUer 

 has referred to only one figure, which is Gualter's, of Bulla 

 fontinalis, and from this the description entirely differs. 

 Muller has described the length to vary from two to eight 

 lines, and the breadth from one to five, but Bruguiere says 

 lie never found a shell larger than three lines long, and one 

 line and two-thirds broad ; it differs from H. auricularia iu 

 being less ventricose, and in having the spire more produced, 

 and from H. palustris in being more conical ; it appears 

 also by the figures to have the spire more produced, and to 

 be less distended than H.putris, which moreover is not an 

 amphibious species.

 Gualter, t. 5. f. H, Schroeter Erdconch. 1. 1. f. 2. 

 Inhabits wet places on aquatic plants, in most parts of Europe. 

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

 broad, and its form is more oblong than that of H. putris, 

 from which it also differs in having only three whirls. 

 Schroeter in the Einleitung, Muller, Chemnitz, and Gmelin, 

 have confounded several references which belong to this 

 species with those of H. putris ; and the error probably ori- 

 ginated with Geoffroy, who has referred to Lister, though 

 his own description as well as Duchesne's figure seem to 

 have been made from H, succinea. It is said in the Fauna
