various species were encountered. At most of these places, specimens of Sebastes were 
taken, this species bemg found in some considerable numbers at from 100—200 metres 
depth above the great depression of the Norwegian Sea. These fish are presumably 
to be found regularly throughout this water; the quite young larvae have also been taken 
there. Herring have been encountered at various places north of the North Sea Bank 
and the Faroe-Iceland ridge, where they were taken in drift nets at or near the surface 
above the deepest parts. A great number of hauls were made throughout the range 
from Lofoten to Jan Mayen; only in a single instance, however, were some few speci- 
mens taken. The same applies to cod, haddock, coalfish, and catfish (Anarrhicas). Ex- 
periments of this nature are however, by no means easy to carry out, and negative or

mainly negative results are scarcely sufficient to warrant the conclusion that the species 
in question do not occur in any quantity in the waters investigated; there is always the 
possibility that the fish might occur in shoals, which it would be a matter of merest chance 
to encounter in so great an expanse of sea. One thing at least is certain; we have no 
other grounds for supposing the existence, in any considerable numbers, of coastal fish 
in the deeper parts of the Norwegian Sea, beyond the occurrence of Sebastes (through- 
out the greater part of the region) and herring from the North Sea slope towards the 
so-called “Bottlenose Ground” (north of the Faroes). 
Principal species only found on the coastal banks in spawning time. 
The most favourable season for investigations of this nature is the spawning time, 
when it it is possible to study the occurrence, not only of the fish themselves, but also
