same authoress gives a list of the Italian species of Sphcerium (4), Culy- 
culina (1, with 2 varieties), and Pisidiuni (12), their determinations (2 
new) being reviewed by S. Clessin, Bull. Soc. mal. Ital. vi. pp. 159-181.

Piedmont. List of 138 land and G8 freshwater Mollusks, including 
several new species, by M. Lessona. Among the more remarkable are 
Helix cameroni., sp. n., allied to II. gougeti (Terv.), from Spain and 
Algeria, and the section Cliarpentieria of Clausilia^ which is almost con- 
fined to Piedmont, with 3 known and 2 new species. The author distin- 
guishes four regions — (1) Alpine region, rich in species of Vitrina^ 
Clausilia, and Helix, sections of Ancliialoma and Campy Icea ; (2) Sub- 
Alpine ; (3) Apennine, characterized by species of Mesompliix, Pupa, 
Xerophila, and Cyclostoma ; (4) Sub-Apennine region. The number 
of terrestrial .species is greater in the Alpine and Sub-Apennine regions ; 
that of freshwater species in the Sub-Alpine and Sub-Apennine. Atti

Sub-Alpine zone, from 1500 feet upwards.
