no ESMARK : MOLLUSCA OF NORWAY. 



Subgenus HELICOGENA Risso. 



Helicogena pomatia L. This species must be excluded 

 from the Ust of our mollusca. Mr. J. Friele has named 

 the botanic garden in Christiania as its locality. I have 

 spoken to the head-gardener, who has been there for thirty 

 years or more, but he assured me that he has never seen 

 anything like this shell in the garden. About twelve years 

 ago, Prof. R. Collett brought some from Denmark, but 

 they have all vanished, so also some I took with me from 

 Sweden ; they have probably been eaten by foxes or 

 Erinaceus, which live everywhere in the neighbourhood of 

 Christiania. Last year I again got some from Sweden, and 

 had them put in the park at Jarlsberg. But I cannot at all 

 consider it to belong to our fauna.
