Rev. Canon Norman — A Month on 



soundings given of the bottom of the fiord for a few miles 

 round Eodberg all range from 250 to 280 fathoms, while the 

 fishermen state that at certain spots 300 fathoms are exceeded. 

 I have therefore when intimating the bed of the fiord given it 

 as " 250-300 fathoms." 



The Bottom of the Fiords. 



The bottom is a verj fine greyish mud. With the excep- 

 tion of Echinodermata (more especially Asteroidea), Actinozoa 

 of the families Virgulariadte and Pennatulidaj, and the giant 

 Lima excavata (which, however, more usually is found 

 attached to the precipices), the animals which inhabit this 

 mud are for the most part of small size. The Mollusca are 

 almost all white or pale in colour or olivaceous green ; as 

 typical species in that depth the following are given : —

 but very fine examples of them from tliat locality have been collected by 

 Herr Storm and are in the Trondbjem Museum.
