deposited in comparatively shallow water, have been 

 deposited at great depths." 1 



In 1864, Professor Sars made a great addition to 

 his list of species from depths of from 200 to 300 

 fathoms off the coast of Norway. He remarks : 

 " The species of animals named are not certainly very 

 numerous (92), yet when w r e consider that most of 

 them were taken accidentally, attached to the lines 

 of the fishermen, and that only in a few instances the 

 dredge was used at these great depths, it will be seen 

 that there is a very interesting field here for the 

 Naturalist furnished with the proper instruments/' 



In 1868 Professor Sars made a still further addi- 

 tion to the deep-sea fauna of the Norwegian Seas ; 

 an addition so important, that he remarks " that it 

 is so great as to give a tolerably complete idea of 

 the general fauna of these coasts." This increase of 

 knowledge, Professor Sars states, is almost entirely 

 due to the indefatigable labours of his son, G. O. 

 Sars, an Inspector of Fisheries under the Swedish 

 Government, who took advantage of the opportuni- 

 ties given by his occupation to dredge down to 450 

 fathoms on some parts of the coast, and among the 

 Loffoten Islands. Sars likewise acknowledges many 

 contributions from his old fellow-labourers, Danielssen 

 and Keren. The number of species from depths be- 

 tween 250 and 450 fathoms on the coast of Norway 

 now reaches 427, thus distributed :
