HELIX. 245 



H. AMMONIS, Schmidt, PI. 60, figs. 93-96; PL 59, figs. 86-88. 



Moderately umbilicated, whitish, banded; last whorl slightly 

 descending in front, aperture rounded, with chestnut or violaceous 

 callus within the upper lip. Diam. 15-20 mill. 



Northern Italy, Dalmatia. 



H. candicans, De Betta and Mart, is a synonym. Marchioness 

 Paulucci writes that it is almost impossible to separate this species 

 from H. neglecta. The umbilicus is narrower than in the typical 

 ericetorum, but I suspect that it will prove to be only a variety of 

 that species. 



Var. DISCREPANS, Tiberi. Figs. 86-88. 



Widely umbilicated, smooth, scarcely striulate, shining, whitish, 

 not banded ; whorls 6, slowly increasing, the last narrow, de- 

 scending in front, aperture oblique, chestnut within ; peristome 

 simple, acute, remotely labiate. Diam. 24 mill. 



Abruzzi, Ancona, Italy. 



H. ERICETORUM, Miill. PI. 60, figs. 97-99.

 brownish, concolored or variously banded with corneous or chest- 

 nut, apex chestnut colored ; whorls 5-6, somewhat flattened, 

 deflected in front ; peristome simple, slightly labiate within.
