NORMAN : ON THE jMOLLUSCA OF BERGEN FIORDS. 65 . 



Out of the 353 Bergen Mollusca, (see page 34) — 



272 = 77-05 per cent, are found at Shetland. 



290 = 82.15 „ ,, „ Britam. 



5, ,, ,5 Denmark. 



,, „ J, Christiania. 



„ „ „ Faroe. 



,, ,, „ Iceland. 



„ ., „ Greenland. 



„ „ ,, N.E. America. 



„ ,, „ Mediterranean. 



The last number is very surprising. Of course the area is 

 very large as compared with most of the preceding districts, hut it 

 also shows how well that area has been worked by the many able 

 Mediterranean malacologists. 



Though in these per centages the Nudibranchiata have been in- 

 cluded, they have been so little attended to in most of the districts 

 that no conclusion can be drawn from their known presence or 

 apparent absence. They are therefore altogether omitted in the 

 numbers and lists with which I bring this paper to a close. These 

 lists, together with the tables (page 16-34), will sujDply complete 

 catalogues of the MoUuscan Fauna — as far as known to me — of 

 Shetland, Denmark, Christiania, Faroe, and Iceland, and bring 

 before us the mollusca from among v/hich probable additions to 

 the Bergen Fauna may be expected.
