NORMAN: ON THE MOLLUSCA OF BERGEN FIORDS. 1 5 



15, 20, 26. — Leerosin, 80-120 f. 36 mollusca, 



16. — Bukken, 5-40 f. 55 mollusca. 



17. — Entrance to Fane Fiord, between Korsnes and Selo, 50- 



120 f. 52 mollusca. 

 18 and 25. — Kors Fiord to the south of entrance to Bukken, 



100-200 f. 18 mollusca. 

 19. — Off Bornestangen in Sartoro, 15-40 f. 63 mollusca. 

 21. — Haakelsund, Ivors Fiord, 3 f. 38 mollusca. 

 22. — Off Haakelsund, Kors Fiord, 200 f. 18 mollusca. 

 23. — Kors Fiord, south side, 180 f. 85 mollusca. 

 24. — N.E. of Bukken (Bay off Sonningen) 5-40 f. 56 fathoms. 

 27. — N. of Bukken, off Sletttin, 5-80 f 64 mollusca. 



The exact depths given must in the case of these Fiords be 

 received with some degree of caution, first, because even littoral 

 shells such as Mytilus and Littorina will be washed down the 

 precipitous faces of the cliffs and be dredged often in 100-200 

 fathoms; secondly, because the variation in depth is so sudden 

 that a dredge let down in 200 fathoms may after it has been 

 drawn two or three hundred yards be then either in 100 fathoms 

 shallower or 100 fathoms deeper water. For example, from the 

 character of the animals procured, I am disposed to think that 

 No. 19 must have descended to a greater depth than was 

 supposed.
