"It is distinguished from all forms of A. trun-catella by the 

 flattened, more rapidly increasing whorls, parted by a scarcely 

 impressed suture, and the hair-fine, vertical rib-striae; also 

 the aperture appears less contracted below, therefore not of a 

 rounded triangular shape, but approaching semi-ovate. 



"Pfeiffer described this species as toothed, so that Clessin 's 

 var. armata seems to be superfluous. The relations of breadth 

 of the last two whorls are pretty variable, and differ in ex- 

 amples from the same place, so that the var. cccsa Wstld. is 

 also to be set down as an individual variation" (Sturany arid 

 Wagner). 



This species was included under P. truncatella by Bielz, 

 who described five varieties of that species, thus : 



a. Aperture entirely unarmed. Govasdia and on Mt. Kac- 

 zanyas at Vajda-Hunyad. 



b. A fold in the left upper corner of the aperture, at the 

 confluence of parietal with columellar margin. At the Csetate 

 boli cavern in the Schieltal. 



c. On the parietal wall a small lamellar tooth. This variety 

 from Turkey not found in Siebenbiirgen. [This refers appar- 

 ently to Kuester's pi. 4, figs. 24, 25.] 



d. Upon the parietal wall a lamellar tooth, and a fold in 

 the right and left angles; further, there is sometimes a den- 

 ticle on the columella and also an impression of the outer lip, 

 thickened tooth-like. [This form was subsequently named 

 var. ar/?iata Clessin.] 



e. [This was later named var. lamellata Clessin, see no. 10.] 



Clessin 's figure of his var. armata is reproduced in pi. 19, 

 fig. 1. It has been reported from Transylvania : Mt. Mogura 

 near Bar and on the Piatra Sipotului at Petrosz (Bielz) ; 

 Piatra Zenoga in the Schiel Mts. and on the Piatra Sipotului 

 and the Piatra Barului in the Strell Mts. (Kimakowicz). 



The var. cccsa Westerlund was thus described : ' ' Shell slen- 

 der, the last and penult whorls of equal width, columellar 

 margin of the aperture having a rather deep incision above
