NORMAN: ON THE MOLLUSCA OF BERGEN FIORDS. 75 



the English and Norwegian coasts. The fact that I procured 

 many more species in three weeks near Bergen than the 'Pomme- 

 rania' was able to collect in twice that time when ranging over 

 the whole of the North Sea, bears wdtness to the richness of the 

 Bergen Fauna. Moreover, many of the rarer mollusca would 

 have found no place in the 'Pommerania's' list had not that vessel 

 paid a visit to Bergen, when opportunities were taken advantage 

 of by dredging in Ivors Fiord and near Bukken. The following 

 mollusca are to be found in Dunker and Metzger's list which are 

 not in the Bergen Fauna.
