increasing whorls, parted by a deeper suture, as well as by 

 the stronger, more widely-spaced and distinctly oblique rib- 

 striffi ; whilst the apertural characters of both species are very 

 similar and equally variable" (Sturany and Wagner). 



Kuester 's figure is photographed in our fig. 5; but it is 

 rather poor. A typical specimen from Carinthia (fig. 2) 

 measures, length 3.9, diam. 1.6 mm., 6% whorls, 12 riblets in 

 1 mm. on the face of the last whorl. Another having a fold 

 in the left upper angle, and a stronger lip-callus (figs. 3, 4), 

 measures 3.6 x 1.55 mm., and has 10 to 11 riblets in 1 mm. 



13a, A. truncatella formosa ( ' Parr. ' Pf r. ) . PL 19, figs. 6, 7, 8. 



Larger, more finely costulate ; 8 whorls ; outer margin of 

 peristome impressed outside. Length 5*4, diam. 2 mm. (Pfr.). 



Larger, more slenderly cylindric, with 7 to 8 whorls and 

 three folds on the parietal wall, of which the median one is 

 raised lamella-like, and penetrates far within. Length 5 to 

 5.5, diam. 2.6 mm. (Sturany and Wagner).

 to 14. 



Shell more slender than the type [of truncatella] , distantly 

 costulate ; aperture with a distinct parietal lamella and armed 

 with a large callous denticle in the middle of the outer mar-

 diam. l 1 /^ mm. (Bttg.).
