erhvervedes. og de have lier vist sig at kunne opnaa en 

 endog betydeligere Størrelse, end de, der ere kjendte fra 

 de øvre Vandlag. Maaske bør alle disse opfattes som væ- 

 sentligt beboende de dybere Vandlag, men naar visse gun- 

 stige Betingelser ere tilstede, formåa de ogsaa at stige op 

 til Overfladen. Til disse Dyreformer hører fremfor alle 

 Amphipoden Themdsto libellvla, Mandt (af Hyperidernes 

 Familie), der i store Mængder forekommer paa de fleste 

 Steder i Ishavet; denne Art udgjorde Hovedbestanddelen 

 af de undersøgte Arters Føde. og manglede neppe ganske 

 hos nogen af dem. skjønt disse kunde tilhøre Arter, der 

 beboede omkring 1000 Favnes Dyb, og paa Grand af sin 

 Legemsbygning med Vished kunde antages ikke at være 

 istancl til at hæve sig synderlig! fra Bunden. Det samme var 

 Tilfældet med enkelte Calanider, og tiere andre pelagiske ■ 

 Crustaceer. 



Nedenfor meddeles en Fortegnelse over alle de Sta- 

 tioner, paa hvilke Dybvandsfiske erholdtes, tilligemed det 

 paa hver enkelt Station erholdte Udbytte 1 .

in which deep-sea fishes were met with, where they 

 attain even a larger size than those taken in the upper 

 strata of the water. All of these forms should, per- 

 haps, be regarded as occurring chiefly at great depths, 

 but gifted with the faculty of ascending, under certain 

 favourable conditions, to the surface. Among such forms 

 must be ranked above all the Amphipod Themisto Hbellida, 

 Mandt (of the family Hyperidce), which is found in 

 enormous quantities in most parts of the Polar Sea; 

 this animal had constituted the chief food of the species 

 examined, and traces of its presence were probably not 

 altogether wanting in any one of the examples, though 

 belonging even to species that occur at a depth of about 1000 

 fathoms, and which from their bodily structure may with 

 certainty be assumed not to ascend far from the bottom. 

 Such. too. was the case with the Calanids and other species.
