38. Boreophausia inermis, (Kröyer).

Ogsaa for denne Fonn har jeg været nodt til at
opstille en egen Slægt, da den har vist sig at være generisk
forskjellig saavel fra Slægten Thysanopoda som fra Slægten
Euphausia, hvortil jeg tidligere har henfart den. To andre
nordiske Euphausiider horer ind under samme Slægtstype,
nemlig Thysanopoda negleda Kröyer og Th. Baschii M. Sars,
muligens ogsaa 77). longicaudata Kröyer.

Exemplarer af den her omhandlede ved vore nordlige
Kyster meget almindeligt forekommende Art toges under
Expeditionen ved Jan Mayen og i Havet mellem denne 0
og Island. Den er forst beskrevet af Kröyer fra Grønland
og ogsaa noteret fra Spitsbergen og Nordamerikas Østkyst,
hvorfor den utvivlsomt er at betragte som en ægte arktisk
Form.

38. Boreophausia inermis, (Kröyer).

For this form, too, I have had to institute a separate
genus, the animal having proved generically distinct alike
from the genus Tliysanopoda and the genus Euphausia,
to the latter of which I had previously referred it. Two
other Northern Euphausiidans belong to the same generic
type, viz. Thysanopoda negleda Kröyer and Th. Baschii
M. Sars, possibly too Th. longicaudata Kröyer.

Examples of the species treated of here, a very
common one off the northern shores of Norway, were taken
on the Expedition at Jan Mayen and in the tract of ocean
extending between that island and Iceland. The species
was first described by Kröyer, from Greenland, and has
also been recorded from Spitzbergen and the east coast of
North America; hence, it must unquestionably be regarded
as a true Arctic form.

39. Thysanoessa tenera. G. O. Sars.

Oversigt over Norges Crustaceer I.

Denne lille zirlige, af mig först i Varangerfjorden
fundne Art observeredes under Expeditionen paa 4
forskjellige Stationer i det aabne Hav mellem Norge og Jan
Mayen. Alle Exemplarer erholdtes ved Hjælp af
Over-Hadenettet.

39. Thysanoéssa tenera, G. O. Sars.

Oversigt over Norges Crustaceer I.

This diminutive, graceful species, discovered by the
author in the Varangerfjord, was met with on the
Expedition, at 4 different Stations, in the open sea, between
Norway and Jan Mayen. All of the specimens were
obtained in the surface-net.

Fain. Mysidæ.

40. Boreomysis tridens, G. O. Sars.

Exemplarer af denne Art toges under Expeditionens
sidste Togt i Vestfjorden (Ståt.. ,255) paa 341 Favnes Dyb.
Foruden i Vestfjorden, hvor jeg forst fandt den, er den
kun observeret i Trondhjemsfjorden af Conservator Storm,
ligeledes paa betydeligt Dyb. Ganske nylig har jeg ogsaa
truffet den i Foldeufjord paa lignende Dyb.

Kam. Mysidæ.
40. Boreomysis tridens. G. O. Sars.

Examples of this species were taken, on the last
cruise of the Expedition, in the Vestfjord (Ståt. 255), at a
depth of 341 fathoms. Exclusive of the Vestfjord, where
-I first observed it, the animal has been taken in the
Trondhjemfjord only, by Mr. Storm, also at a considerable
depth. Quite recently I have also met with the species in
the Foldenfjord, at similar depths.
