deposited in comparatively shallow water, have been 
deposited at great depths.’’’ 3 
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 we 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 Koren. The number of species from depths be- 
tween 250 and 450 fathoms on the coast of Norway 
now reaches 4.27, thus distributed :—
