Det samlede Antal af de under Expeditionen
observerede Arter af Krebsdyr er herefter, fordelte paa de
respective Ordener, følgende:
Nye Al-ter.
Podophthalmia.......OU ... . 5
Cumacea.........30 ... . 1
Isopoda.........52 .... 15
Amphipoda........1-19 .... 38
Branchiopoda.......13......
Ostracoda.........9 ... .
Copepoda.........15 ... . ,.
Cirripedia........9 . . . . 5
Tilsammen 337 .... 64
Hovedmassen af disse Arter er aabenbart af arktisk
Oprindelse, hvilket tydeligt nok fremgaar af deres hidtil
bekjendte geografiske Udbredning. For de nye Arters
Vedkommende, er alle de i den kolde Areas Dyb
forekommende ganske utvivlsomt arktiske, og dette er ogsaa
for enkelte af dem allerede direkte bleven godtgjort ved
andre Forskeres Undersøgelser.
Af sandsynlig sydlig Oprindelse er kun folgende 43
Arter:
Thranites rélox,
Atdecyclus septemdentatus,
Scyramathia Carpenteri,
Eupagurus tri carinatus,
Gcdatliea nexa.
,. intermedia,
Munida tenuimana,
Cheraph ilus ech innlat iis.
neglectus,
Pandalus leptorhynchus,
Lophogaster typicus,
Erytltrops pyçjmæa,
Cuma scorpioides,
Cyclaspis longicaudata.
EudoreUa truncahda,
Pseudocuma cercaria,
Anceus maxillaris,
Jtocinela danmonietisis,
Oirolana borealis.
Flcurocrypta galatlieæ,
Lysianassa Costæ,
Bathyporeia pilosa.
The various forms oi Crustacea observed on thi*
Expedition. were accordingly, when arranged under the respective
orders, found to comprise the following number of species: —
New Species.
Podophthalmia.......60 ... . 5
Cumacea.........30 ... . 1
lsopoda....... . 52 . . . . 15
Ampliipoda........149 .... 38
Branchiopoda.......13......
Ostracoda.........9 . . . . ,.
Copepoda.........15 ... . ,.
Cirripedia........9 . . . . 5
337 .... 64
By far the greater number of these species are
evidently of Arctic origin, a fact evinced by their geographical
distribution, as yet known. As to the new species, those
occuring in the deeps of the Cold Area are all, without
doubt, true Arctic forms; and regarding some this has
already been shown by the researches of other naturalists.
The following 43 only are probably species of
southern origin:
Thranites relox,
Atelecyclus septemdentatus,
Scyramatliia Carpenteri.
Eupagurus tricarinatus.
Galatliea nexa,
,. intermedia,
Manilla tenuimana.
Cheraphilus echimdatus.
„ negledus,
Pandalus leptorhynchus.
Lophogaster typicus,
Erythrops pygmcea.
Cuma scorpioides,
Cyclaspis longicaudata.
Eudordla truncatula.
Pseudocuma cercaria,
Anceus maxillaris,
Bocinela danmonietisis,
Cirolana borealis.
Pleurocrypta galatlieæ,
Lysianassa Costce,
Bathyporeia pilosa.
