følgende kommer at omtale en del stationer udenfor den 
norske kyst og fra de større dyb i Grønlandshavet, vil man 
se, at det kan have den største betydning at være stræng 
kritisk i angivelsen af enten man har havt levende eller 
døde skaller for sig. 
Med hensyn til nomenclaturen og synonymien har vi 
for de fleste arters vedkommende indskrænket os til at an- 
give det arbeide, hvor arten første gang blev beskrevet 
samt nogle af de vigtigere værker, hvor den er omtalt. 
Kun hvor der hersker konfussion angaaende nomenclaturen 
har vi for nærmere at præcisere vor opfatning leveret en 
udførligere synonymiliste.

Før vi nærmere omhandler de paa expeditionen fundne 
arter, vil vi omtale nogle stationer, som har særlig inter- 
esse, dels paa grund af sin rigdom paa arter, dels paa 
grund af forekomster af dyrelevninger paa eiendomme- 
lige dyb. 
Allerede paa det skandinaviske naturforskermøde i 
Christiania i 1844 henledede professor Rasch opmærksom- 
heden paa det rige dyreliv paa fiskebankerne udenfor 
Aalesund. Senere har professor G. O. Sars i ,,Bidrag til 
Kundskaben om Dyrelivet paa vore Havbanker**) nærmere 
redegjort for de dyreformer, som holder til paa bankerne 
udenfor Aalesund og Christiansund. 
Et lignende og endnu rigere dyreliv lykkedes det 
Nordhavsexpeditionen at paavise paa bankerne udenfor det 
nordlige Norge. De rigeste lokaliteter var station 195, 
107 fr., paa banken nord for Senjen, samt station 173 b, 
300 fv. og station 192, 649 fv., vest af Senjen, begge paa 
bankens afheld mod dybet.

to living specimens. When we come to speak in these 
pages of certain stations off the Norwegian coast and in 
the greater depths of the Greenland Sea, it will be seen 
how great is the importance of a severely critical statement 
as to whether the specimens mentioned were alive or dead. 
With regard to the nomenclature and synonymy, we 
have confined ourselves in the case of most of the species 
to a statement of the work in which the species was first 
described, and of some of the more important works in 
which it is mentioned. It is only where there is any con- 
fusion regarding the nomenclature, that we have given a 
fuller list of synonyms in order precisely to define our view. 
During the Norwegian North Atlantic Expedition, 
there were found

Before discussing more fully the species found during 
the expedition, we will mention some stations that are of 
special interest, partly on account of their wealth of species, 
partly because of the occurrence of animal remains at 
unusual depths. 
As early as 1844, at the meeting of Scandinavian 
naturalists in Christiania, Professor Rasch drew attention 
to the abundant animal life on the fishing banks off Aale- 
sund. Subsequently Professor G. O. Sars in his ,,Bidrag 
til Kundskaben om Dyrelivet paa vore Havbanker“?), gave 
a fuller account of the animal forms frequenting the banks 
off Aalesund and Christiansund. 
The North Atlantic Expedition succeeded in proying 
the existence of a similar, and still more abundant, animal 
life on the banks along the coast of northern Norway. 
The richest localities were Station 195 (107 fathoms), on 
the bank to the north of Senjen, and Stations 173 b (300 
fathoms) and 192 (649 fathoms), west of Senjen, both on 
the slope of the bank, towards deep water.
