The Helix sericea of Draparnaud, JeflFreys, Turlon, 

 Lamark, Pfeiffer, and Rossmassler is no doubt better 

 known in this country as the H. granulata of Alder, 

 Grey, and Brown. 



Described by Montagu, in 1803, in his '* British 

 Testacea," under the name of H. granulata. 



It must not be confused with the Helix sericea of 

 Brown and Grey, which is only a very hisp'id form of 

 H. hispida. 



The shell is globular, yet slightly depressed, pellucid, 

 exceedingly downy, fragile, aperture roundish lunate, 

 umbilicus very minute; pale horn-colowr. From five 

 iQ six swollen convolutions. 



Diameter of the shell nearly the third of an inch. 



Colour of the animal yellowish white, the mantle 

 being marbled with black, the spots of which are 

 visible through this thiu shell. 



It is a widely spread, although a somewhat local, 

 species. 



Inhabits damp places, especially amongst moss in 

 moist woods.
