146 HELIX. 



H. ALONENSIS Ferussac. PI. 43, fig. 78-82. 



Covered perforate, depressed globose, somewhat solid, yellowish 

 white, variegated with streaks and marblings of light brown, or five 

 fasciate; irregularly striate, decussated with fine revolving lines; 

 whorls 4-5, slightly convex, rapidly increasing, the last large, tumid, 

 deflexed anteriorly ; aperture large, rotund lunar, oblique ; peri- 

 stome narrowly reflexed, appressed at base, the ends converging, 

 joined by a very light callus. Diam. 30. mill. 



Southern Spain ; Balearic Is. 

 An abundant and extremely variable species. 



Var. CARTHAGINIENSIS Rossm. PI. 44, fig. 86-89. 



Similar in general characters and sculpture to H. alonensis, but 

 smaller, more depressed, aperture more oval on account of the 

 greater deflection of the last whorl ; usually conspicuously five- 

 fasciate ; lip well expanded. 



Diam. 24 mill. 



Sierra da Cartagena, Spain. 



Differs from H. campesina in being imperforate, with less devel- 

 oped peristome, which is reflected and adnate to the base of the*" shell. 

 The genitalia offer some points of difference, according to Ross- 

 msessler ; but until we have descriptions or figures of those of the 

 allied forms we can scarcely make use of this character. 



Var. CAMPESINA Ezquerra. PI. 43, figs. 83-85. 



With the markings and sculpture of H. alonensis this variety ex- 

 hibits a much more oblique nearly perfectly oval mouth, broadly 

 expanded and reflexed peristome, scarcely or not at all appressed to 

 base, its extremities converging and connected by a decided callus ; 

 umbilicus wide or sometimes nearly covered by the reflection of the 

 lip. Diam. 40 mill. 



Spain, provinces Marcia and Valentia. 



Rossmsessler's var. lorcana is synonymous. 



A mountain form. 

 Var. LOXANA Rossmsessler. PI. 44, figs. 90-93. 



Imperforate, depressed globose, usually five-fasciate, the upper 

 bands interrupted ; aperture very oblique, rounded lunar; peristome 

 expanded, margins converging, dilated over the umbilical area.
