238 HELIX-POM ATIA. 



Allied to H. ceratomma Pfr., but having a wider umbilical chink, 

 the lip-terminations more approaching, joined by a thin (in old 

 examples a thick) callus ; the spiral sculpture is developed only on 

 the last whorl above, and is much weaker ; and the aperture is less 

 oblique. 



H. NINIVITA Galland. PL 34, figs. 55, 56, 57. 



Shell broadly umbilicated (the umbilicus much dilated toward the 

 aperture and elliptical), depressed, slightly convex ; strongly 

 striated above, finely below ; unicolored whitish or gray-white, with 

 faint white flecks and two interrupted chestnut-brown bands. 

 Whorls 5, irregularly increasing, the first two flattened, acutely 

 keeled at the suture, the following narrowly coiled, somewhat con- 

 vex, the last whorl very large, rounded, elevated above the penult- 

 imate in front and then deeply descending. Aperture very oblique, 

 transversely oval-rotund ; peristome continuous, thick, broadly 

 expanded and reflexed.

H. MAZZULOPSIS Ancey, u. sp. PI. 46, figs. 41, 42. 



Shell globose conoid, higher than broad, imperforate, rather thin ; 

 whitish-corneous under a very thin (deciduous ?) yellowish cuticle, 

 with 5 dark brown bands, the 3d and 4th wider; and sculptured with 

 very unequal, irregularly spaced, opaque white, oblique wrinkles. 

 Spire conoidal, apex obtuse, the earlier H whorls smooth, corneous, 

 brown at the sutures ; following whorls banded and wrinkled, very 

 rapidly increasing, the last sloping above, ventricose below, descend- 

 ing in front. Aperture oblique, ovate, showing the bands within ; 

 lip simple, thin ; columella broadly arcuate. 



Alt. 32, diam. 27 mill. ; oblique alt. of aperture 25 mill. 



Alt. 38, diam. 32 mill. ; oblique alt. of aperture 28 mill.

This species differs markedly from H. mazzulii in the coarse, 

 unequal, unevenly spaced white wrinkles. It resembles the Sicilian 

 species in contour. I have been unable to find any description or
