P. cibtusale is not well-known on the Continent. It has been seen 

 from Iceland [F. H. Sikes Coll.], Scandinavia [Lynge Coll.], Bavaria 

 [Norman Coll., B.M. 98.5.20 : 22268-71], Russia [Lindholm Coll.], 

 Chamouni [Coll. Marquess de Monterosato very dwarfed], and 

 judging from Baudon's figures (9, pi. i, f. E) occurs in Franco. 

 When better known it will probably prove to inhabit Europe north 

 of the Alps. 



Fossil it has been recorded from the Holocene and Pleistocene 

 of Denmark [Johansen (85, p. 9)] : and recognized in the Pleistocene 

 (Campinien and Hesbayeu) of Soignes, Belgium [Mus. Hist. Nat. 

 Brussels]. P. fossile, Sacco, from the Pliocene of Piedmont is 

 closely allied.
