Distinguished from typical pallida by the presence of small 

 angular, parietal and columellar teeth ; but these are variable 

 in development in adult shells of the same lot. In some of the 

 examples from Nervi, Liguria, the angular and parietal are 

 reduced to slight traces (pi. 4, fig. 5), and there is no colu- 

 mellar. Such specimens approach the original pallida rather 

 closely, but all I have seen are slightly larger, 9y 2 to 10 mm. 

 long. Other shells of the same lot have two distinct teeth and 

 a trace of the columellar, or none. Specimens from Spezia 

 have the three teeth distinct (pi. 4, fig. 8). This may be 

 taken as type locality of amicta, since Pfeiffer gave only Sicily 

 (1854) and northern Italy (1859). 



Specimens from Grasse (Terver) have the lip more ex- 

 panded than Italian shells seen ; two teeth, with rarely a 

 small columellar also (pi. 4, fig. 6). The parietal is often not 

 visible in a direct face view. They vary in size : 



Length 12, diam. above aperture 3.3 mm. ; 9 whorls. 



Length 9.5, diam. above aperture 3 mm. ; 7y 2 whorls. 



Although amicta has been reported from the Chateau d'lf 

 (Dep. Bouches-du-Rhone) and the peninsula of Saint-Man- 

 drie, near Toulon ( Bourguignat, I860), and I have specimens 

 from Grasse (Var), yet it appears to be wanting in the Dep. 

 Alpes Maritimes, where the snail fauna has been studied care- 

 fully by Ct. Caziot and many others. It occurs at suitable 

 places along the whole coast of Liguria, but the colonies, while 

 rather numerous, appear to be of limited extent. 



According to Issel, C. amicta ordinarily lives on limestone 

 rocks near sea level, but it has also been found inland and at 

 some elevation, at Bavari and Traso in the Bisagno valley, five 

 or six kilometers from the coast, at about 100 meters elevation, 

 and above Cassagna and Statale, ten to twelve kilometers in-
