Kiister remarks that it is related to P. muscorum in shape, 

 but. somewhat less blunt, and easily distinguished by the pecu- 

 liarly formed aperture. It is very finely, almost inconspic- 

 uously striate. The 7 whorls are nearly flat, the last strongly 

 contracting below. The rounded parietal tooth is fold-like ; 

 peristome straight, hardly thickened; a strong callus on the 

 neck. 



The figure looks like a Lauria rather than Pupilla. It is a 

 lost species, known only by the original account. 



15. PUPILLA TRIPLICATA (Studer). PI. 21, figs. 11, 12, 13. 



The shell is dextral, much smaller than P. muscorum, with 

 a very minute, round perforation ; cylindric Math very blunt 

 summit, smooth or hardly visibly striate, cinnamon-colored, 

 thin, with some luster. 6 to 7 very slowly increasing whorls, 

 moderately convex, with rather deeply impressed suture, 

 the last half-whorl flattened, usually impressed over the lower- 

 palatal fold, having a high, rounded crest behind the lip, fol- 

 lowed by a deep, narrow constriction. The aperture is trun- 

 cate-rounded, armed some distance within with three teeth: 

 a deeply entering parietal lamella, its inner half low, a nod- 

 ular columellar lamella, and a rather long lower-palatal fold, 

 tapering inwardly. The peristome has a thin, narrow reflec- 

 tion and is but little thickened within, the margins converging.
