250 HELIX. 



chestnut bands, which become purplish when slightly weathered ; 

 spire conic, obtuse, apex very large ; whorls 4, the last large, globose, 

 descending anteriorly ; aperture oblique, rotund-lunate, peristome 

 subsimple, the columellar margin chestnut colored, expanded and 

 appressed. Diam. 27, alt. 27 mill.

The synonymy is rather involved : It includes H. obtiitatu (Ziegl.) 

 Rossm., 1838. (preoc), H.obtusa/is Mousson et auct., H. obtusata 

 (Ziegl.) Albers, 1860 (?). The first formal diagnosis published was 

 that of Albers, in I860 ; It is not certain, however, that he describ- 

 ed the real obtusata (Ziegl.) Rossm., because hib diagnosis does not 

 mention the large apex, which is the most prominent character of 

 the species. Rossmaessler simply figured, without descriptions, the 

 obfitxiita of Zeigler and vulgaris of Parreyss.

Differs from the type in the more solid shell, two-banded, one
