erhvervecles, og de have lier vist sig at kunne opnaa en 

 endog bet)'deligere Størrelse, end de, der ere kjendte fra 

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

 sentligt beboende de dybere Vandlag. men uaar visse gun- 

 stige Betingelser ere tilstede, formåa de ogsaa at stige op 

 til Overfladen. Til disse Dyreformer hører fremfor alle 

 Amphipoden Tlwmisio lihellula. 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 Grund af sin 

 Legemsbygning med Vished kunde antages ikke at viere 

 istand til at hæve sig synderligt fra Bunden. Det samme var 

 Tilfældet med enkelte Calanider, og flere andre pelagiske 

 Crustaceer. 



Nedenfor meddeles en Fortegnelse over alle de Sta- 

 tioner, paa hvilke Dybvandstiske erholdtes, tilligemed det 

 paa hver enkelt Station erholdte Udbytte^

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 suiface. Among such forms 

 must be ranked above all the Amphipod Tlwtni-^fo lihellula. 

 Mandt (of the family Hyper idæ), 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 

 certaint}' be assumed not to ascend far from the bottom. 

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