 pi. 5, f. 18, 19 (dist. in Germany). 



This species approaches P. alpestris by the aperture pro- 

 vided with 4 teeth, but it differs considerably by the shell be- 

 ing of dark color, oblong-ovoid, and noticeably larger, nearly 

 as large as a P. edentula of 6 whorls, the palatal teeth short 

 and higher, etc. (Westerlund). 



The figure is from Geyer.
