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 mnn har liavt levende eller 

 døde skaller for sig. 



Med hensyn til uomenclaturen og synonymien liar vi 

 for de fleste arters vedkommende indskrænket os til at an- 

 give det ai'beide, 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 

 ndførligere synonymiliste.

For vi nærmere omhandler de paa expeditionen fundne 

 arter, vil vi omtale nogle stationer, som har særlig inter- 

 esse, dels paa grnnd af sin rigdom paa arter, dels paa 

 grund af forekomster af dj-relevninger paa eiendomme- 

 lige dyb. 



Allerede paa det skandinaviske naturforskermøde i 

 Christiania i 1 844 henledede professor Easch opmærksom- 

 heden paa det rige dyreliv paa fiskebankerne udenfor 

 Aalesund. Senere har professor G. 0. Sårs i „Bidrag til 

 Kundskaljen om Dyrelivet paa vøre 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 

 nordhge Norge. De rigeste lokaliteter var station 195, 

 107 fv., 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 vve 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 

 liovv great is the importance of a severely critical statement 

 as to wliether the specimens mentioned were alive or dead. 



A\^ith 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 

 vs'hich it is mentioned. It is only where there is any con- 

 fusion regarding the nomenclature, that we have given a 

 fuUer list of synonyms in order precisely to define our view. 



During the Norwegian North Atlantic Espedition, 

 there were found 



8 species 



. witli 9 varieties.

Before discussiug more fully the sjDecies found during 

 the expedition, we will mention some stations that are of 

 special interest, partly on account of their wcalth 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 tishing banks off Aale- 

 sund. Subsequently Professor G. 0. Sårs in his ..Bidrag 

 til Kundskaben om Dyrelivet paa vore Havbanker"'), gave 

 a tuller account of the animal forms frequenting the banks 

 off Aalesund and Christiansund. 



The North Atlantic Expedition succeeded in prøving 

 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 fathoras), on 

 the bank to the north of Senjen, and Stations 173 b (300 

 fathoms) aud 192 (649 fathoms). west of Senjen, both on 

 the slope of the bank, towards deep water.
