Linnaeus has not given any reference, and to the above specific 

 character has only added the following short description : 

 ** Shell as large as a hazel-nut, and white, with one brown 

 band." Da Costa and Montagu have conjectured that H. 

 Ericetorum may be this species. 



LUSiTANiCA. 98. Shell convex, obtuse, with five 

 rounded reversed whirls, and the body-whirl 

 ventricose; umbilicus large.

 Inhabits the South of Europe ; and is a land shell. Linnaus. 



Marshes in Guinea. Chemnitz. 

 Shell about one and a half or two inches long, and nearly glo- 

 bular, of a yellowish brown or whitish colour, or sometimes 

 brown marbled with white, and coated with a dark green 

 epidermis ; the aperture is roundish, with the lip acute, and 

 the umbilicus large ; it is furnished with a leathery diapha- 

 nous operculum. Linnaeus has quoted Gualter, t.2. f.T, 

 and this shell answers his description in other respects, 

 though he has not noticed the reversed direction of the 

 whirls.
