chestnut bands, which become purplish when slightly weathered ; 

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

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

 Rossm., 1838, (preoc), H. obtusalis Mousson et auct., H. obtusata 

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

 that of Albers, in 1860 ; It is not certain, however, that he describ- 

 ed the real obtusata: (Ziegl.) Rossm., because his diagnosis' does not 

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

 the species. Rossmaessler simply figured, without descriptions, th*- 

 obtusata of Zeigler and vulcjaris of Parreyss.
