GRANOPUPA. 341 



Section Rnpestrella Monts. 



Slender Granopupre with the lamellae and plicae small, often 

 wanting wholly or in part; palatal plicae to 2; peristome 

 thin, with slight expansion or none. Shell generally daubed 

 with dirt. 



Type Pupa rupestris Ph. Distribution, Italy and Sicily 

 eastward to Asia Minor, and in Tunis and Algeria. 



Westerlund and Caziot have distributed these forms among 

 several successive groups, natural enough, yet very closely 

 connected. The series is a complex of related forms showing 

 various stages in tooth-reduction, culminating in wholly tooth- 

 less species. This series is parallel to the Chondrina farinem 

 series of Spain, though of course of quite different genesis, the 

 farinesii series being apparently derived from the C. avenacea 

 group. 



Species of Sicily, Italy, Dalmatia, Greece and Asia Minor. 

 2. GRANOPUPA PHILIPPII (Cantraine). PI. 48, figs. 12, 13, 14. 



The shell is shortly, deeply rimate, oblong-conic, russet, 

 finely rib-striate, the striae usually somewhat irregular. First 

 whorl large, projecting, retuse at apex, very minutely granu- 

 lose ; following whorls strongly convex, the penult somewhat 

 swollen, last whorl somewhat flattened behind the lip, not 

 ascending. Aperture oblong. Angular lamella very small 

 and short, parietal much larger though small; columellar 

 lamella equal to the parietal and equally immersed, subcolu- 

 mellar very minute ; palatal plicae two, the upper much larger, 

 not reaching the peristome, the lower less emerging [and 

 sometimes wanting] . Peristome thin, whitish, the outer mar- 

 gin scarcely expanded, columellar margin broadly triangu- 

 larly dilated ; the margins approach, and are joined by a thin, 

 transparent parietal callous. 



Length 4, diam. 1.6 mm.; 5% whorls (Capri). 



Length 3.9 to 4.2, diam. 1.8 mm. (Prevesa).
