Z. ALGIRUS, Linn. PI. 44, fig. 66. 



Widely umbilicated, the periphery obsoletely angulated, very 

 minutely granularly decussated above ; epidermis yellowish 

 corneous, deciduously rayed, base smooth and shining; whorls 

 6, the earlier ones flattened, the body-whorl more rounded.

Southern France, Sardinia, Corsica, Sicily. 



Some authors have preferred the rather objectionable name of 

 Z. oculus-capri, Miiller, because of some doubt as to the deter- 

 mination of the Linnean species. Other synonyms are Helix 

 Lusitanica, Linn., and H. segophthalmos, Gmel. 



Z. VERTICILLUS, Per. PL 44, figs. 67-70. 



Widely umbilicated, peripher} r obsoletely angulated, very mi- 

 nutely decussated above, smooth and shining below ; epidermis 

 light greenish yellow, or brownish yellow, with olivaceous or 

 darker brown occasional strigations. Diam. 33 mill. 



Southern Austrian Provinces. 



Smaller, and more globose than the preceding species. 



The synonyms are H. lapidicola, Muhlf. ; H. algira, Brumati. 

 Dr. Bottger has described a var. Corcyrensis, from Corfu ; it has 

 5J whorls instead of 6 or 7, more distinctly granulated above, 

 periphery more widely angulated. Diam. 29 mill. I also figure 

 a var. Grseca, Kobelt (fig. 68), from the Morea. The same 

 author has described a var. Eubosica (figs. 69, 70), from Mt. 

 Delphi ; the periphery distinctly carinated.

 sated and light yellowish brown above, more yellowish below, 

 with a narrow white peripheral band. Diam. 37 mill.
