-'02 HELIX. 



differ from most of the peninsular species in being marked with 

 minute spiral impressed lines. The Italian species are generally 

 more depressed, and more deeply colored. 



Montfort's type of Iberus is not H. muralis as I stated on p. 122 

 (following Albers and v. Martens) but H. gualteriana of Spain. 

 There may be two subsections recognized : Iberus, s. sir. and Levan- 

 litin. Kobelt, the latter comprising the large forms of Asia Minor. 



The synonymy includes Murella Pfr., and, in part, Crenea Albers. 

 Pfeiffer and other authors have included, also, a number of Canary 

 Island species, which in this work are placed in Hemicyda.
