 named by De Ferussac H. Boiedilchiana.

The measled Helix. Shell umbilicated, depressed, 

 sharply keeled, rather solid, opake, yellowish, very 

 closely plicated at the upper part, and regularly de- 

 cussated with couccntric line--, thick-set with bands 

 of white pustules ; spire rather flat ; whorls three to 

 four, slightly convex, increasing rapidly, last whorl 

 convex, impressed beneath the keel ; columella short, 

 vertical ; aperture broadly wedge-shaped ; lip simple, 

 sharp, columellar margin shortly reflected, almost 

 covering the umbilicus.

The character termed pustules in the description of this 

 curious species is merely an arrangement of superficial 

 white blotches.
