forward and is impressed in the middle, with a pit outside 

 and a strong tooth projecting well into the aperture. There 

 is a tubercular basal fold near the base of the columella. 



Length 4.8 to 5, diam. 1.6 mm.

 sesora) in a beech wood on the left bank of the brook, under 

 rotten wood on the ground (Bielz, type loc).

This species is well distinguished by its narrow aperture, 

 with the tooth of the outer lip large and projecting strongly, 

 the columellar lamella also strongly developed, and by having 

 a distinct basal fold. 



Clessin evidently had not seen the species, merely naming 

 Bielz 's "P. truncatella var. e," and copying that author's de- 

 scription ; but very good descriptions have been published by 

 Kimakowicz and by Sturany and Wagner, who gave the 

 figure reproduced in my pi. 18, fig. 14. Fig. 13 is from a 

 topotype in the Hesse collection. 



Bielz states that "the animal is white, nearly transparent, 

 with flesh-colored liver. When extended the foot is 2V2 lines 

 long, 3/3 line wide, and has very long (1 line) and relatively 

 thick tentacles without terminal knobs, and which, on repeated 

 observation in the brightest light showed no eye-spots." 

 These specimens were found in autumn under about 6 inches 

 of forest debris, near Kerczesoara, in the neighborhood of the 

 Bullabach locality near the Glashiitte formerly given for the 

 same form, var. e. The country rock is mica-schist ; other 

 Transsylvanian stations for the P. truncatella [group] being 

 on limestone.
