Recapitulation. 



Det samlede Antal at' de under Expeditionen obser- 

 verede Arter af Krebsdji' er herefter, fordelte paa dé 

 respective Ordener, følgende: 



Nve Arter. 



Hovedmassen af disse Arter er aabenbart af arktisk 

 Oprindelse, hvilket tydeligt nok fremgaar af deres hidtil 

 bekjendte geografiske Udbredning. For de nve Arters 

 Vedkommende, er alle de i den kolde Areas Dyb fore- 

 kommende ganske utvivlsomt arktiske, og dette er ogsaa 

 for enkelte af dem allerede direkte bleven godtgjort ved 

 andre Forskeres Dndersøgelser. 



Af sandsynlig sydlig Oprindelse er kun følgende 43 

 Arter: 



Thranites vélox,

The various tonns ut Orustacea observed on the Expedi- 

 tion. were accordingly, when arranged under tin- respective 

 orders, found to compfise the following number of species: — 



New S] i 

 PodophtJialmia tin ... . 5

Isopoda ")2 ... . 15 



Amphipoda 149 .... 38 



Branchiopoda 13 ... . ,. 



Ostracoda 9 



Copepoda 15 



Cirripedia '. . 9 . . . . 5 



337 .... 64 



By far the greater number of these species are evi- 

 dently of Arctic origin, a fact evinced by their geographical 

 distribution, as vet known. As to the new species. those 

 occuring in the deeps of the Cold Area are all. without 

 doubt, true Arctic fonns; and regarding some this has 

 alreadv been shown by the researches of other naturalists.
