4 j-5, the last rather wide, convex, its last third rather inflated below, 

 abruptly deflexed anteriorly ; aperture oval, wide, oblique, yellowish 

 flesh-color within, showing the bands ; peristome expanded, white, 

 thickened somewhat within, the upper and lower margins subparal- 

 lel, somewhat converging, the upper straightened, the basal margin

Diam. 25, alt. 18 mill; diam. 26, alt. 16 mill. 



Madonian Mts. Northern Sicily. 



A forma minor (pi. 60, figs. 89-91) measures: diam. 20, alt. 13 

 mill. 



A more flattened form from Castelbuono is figured by Kobelt (pi. 

 65, figs. 52-56.) 



The spiral sculpture will separate this form from the preceding 

 peninsular species. 



II. KUGENIA Pfeiffer, 1853. PI. 65, figs. 48, 49. 



Partly or wholly covered perforate, siibdepressed globose-conic,

 and microscopic decussating spiral lines, sometimes subobsolete; 

 spire depressed conic, apex corneous, prominent, but blunt; suture 

 lightly impressed, linear; whorls 4o, the apical convex, the follow- 

 ing flattened, moderately increasing ; body-whorl subangular at the 

 periphery, suddenly deflexed above; aperture rounded oval, very 

 oblique, yellowish flesh-color inside ; peristome obtuse, its ends con- 

 verging, the baso-columellar margin reflexed and appressed, thick-

 brown spot at its union with the parietal wall. Diam. 14, alt. 9 mill. 



Ficuzza, near Palermo, Sicily. 



H. vigenia Parr, (in sched.) and H. calypso Beiioit are identical. 

 First discovered by Benoit, but the name of Pfeiffer has priority. 



Var. HUETIANA Benoit. PI. 65, figs. 45-47. 



Double the size of H. eugenia, more depressed, and usually slight- 

 ly malleate ; aperture dark within ; carina often obsolete on last 

 whorl. Diam. 21, alt, 12 mill.

H. hueti Pfr. is synonymous.
