Io6 ESMARK : MOLLUSCA OF NORWAY. 



T. hispida var. albina. Krokkleven in Ringerige. 

 Subgenus XEROPHILA Held. 



Xerophila candicans Ziegl. A few specimens found near 

 Fredriksvsern, Christiania Stift, 187 1^ by the late Dr. 

 Poulsen, Copenhagen. 



X. ericetorum Miill. In the Zoological Museum there is a 

 specimen of this species without bands, found many years 

 ago at Bygdd, near Christiania. It has, since then, never 

 been found, although the locality has often been searched. 

 On that account it seems very difficult to explain the 

 presence of one shell. Perhaps it might have been 

 among sand brought with vessels from England or France. 

 I think this the most probable explanation, as, a few years 

 ago, I found a well conserved shell of Helix aspersa in 

 some imported sand near Langesund.
