HELIX. 245 



H. AMMONIS, Schmidt, PI. 60, figs. 93-96 ; PI. 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 

 erieetorum, 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. 



Widely umbilicated, striulate, scarcely shining, whitish or pale 

 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. 



Diam. 15-18 mill. 



France, Germany, Sweden, etc. 



The synonymy includes H. trochlearis, and H. obvia, Andrz., 

 H. Kusteri, Held, H. Itala, Linn.? H. media, Gmel.? H. dubia > 

 Hartm. H. zonaria, Schranck. 



Var. DEVIANS, Westerl. 



Very widely umbilicated, depressed; whorls 6, the last dilated 

 and deflected at the aperture. 



Agen, France; Saalfeld, Germany. 



H. erica, DaCosta, H. umbilicaris, OL, and H. obliterata, Hartm. 

 are synonyms. 



Var. ALBELLA, Penn. 



H. VTJLGARISSIMA, Schlafli. PI. 59, figs. 79, 80. 



Perhaps a variety of H. 9 erieetorum; sometimes yellowish, but
