6o NORMAN: ON THE MOLLUSCA OF BERGEN FIORDS. 



previously been found. But the fact that two hundred and sixty 

 one species and varieties were found in this short time, speaks 

 volumes for the richness of these Fiords. Many of the moUusca, 

 moreover, are northern or abyssal forms which have either only 

 very recently been described, or are still MS. species ; and thus 

 some additions have been made to the already long list of the 

 Bergen district moUusca. 



If the mollusca of the table on pages 32-34 be added to those 

 found by myself we obtain the entire Molluscan Fauna of the 

 district. I have however been unable to include the Cephalopoda, 

 for although aware that many species have been identified by the 

 Bergen naturalists I can only find record of the occurrence of 

 Sepiola Rondeletii, Leach, which was procured by the " Pommer- 

 ania " in Kors Fiord. 



Some mollusca which are in Herr Friele's Bergen catalogue 

 have been omitted here, as they owed their insertion, he informs 

 me, to mistake : — Montacuta Dawsoni, Area obliqua (=A. glaci- 

 alis, which is also recorded), Barleeia rubra, Odostoviia plicata, 

 O. umbiiicata, 0. Warrent, and O. lactea, and Philine catena. 

 Coithiuin indgatum and C. calabrum have also been omitted as 

 not native. The specimens which were procured by Prof M. 

 Sars at Manger, and are now preserved in the museum at 

 Christiania, are old and worn shells. It is probable that they came 

 from ballast. 



There is preserved in the Christiania Museum a fine and quite 

 fresh-looking specimen of Cardium aculcaiiem, which was dredged 

 by Prof M. Sars in Bergen Fiord. On examining this shell carefully 

 I found on it a patch of the cells of the Polyzoon, Lepralia violacea. 

 "Hereby hangs a tale." This Lepralia, like the Cardium on 

 which it had taken up its dwelling, is a southern form, which on the 

 British coast scarcely reaches the south-west of Scotland. It is 

 unknown in the north, nor have I ever seen it from the east of 

 Scotland or north-east of England, and it is unknown in Norway.
