207. Acanthostepheia Malmgreni, (Goes). 
Nogle faa Exemplarer af denne characteristiske ark- 
tiske Form blev under Expeditionen tagne ved Spitsbergen, 
hvor ogsaa Goes forst fandt den. Arten er udbredt til 
Gsthavet, Franz Josephs Land, det sibiriske Ishav og det 
kariske Hav, men er endnu ikke observeret ved vore Kyster. 
208. Aceros phyllonyx. (M. Sars). 
Talrige Exemplarer af denne Form blev under Ex- 
peditionen indsamlede paa forskjcllige Punkter af det af os 
bereiste Havstrog, tildels fra meget betvdelige Dyb, indtil 
1004 Favne. Af Stationerne ligger en (Stat. 48) i Havet 
0st af Island, en anden (Stat. 240) mellem Island og Jan 
Mayen, en 3die (Stat. 273) i Gsthavet, og 4 andre Sta- 
tioner (336, 338, 357, 363) i Havet om Spitsbergen. Dcs- 
uden blev den observeret i Snltenfjord og Tanafjord (Stat. 
261). Arten, der forekommer langs vor liele Kyst, er nordlig 
udbredt til Spitsbergen, Franz Josephs Land og det kariske 
Hav og gaar sydlig til Bohuslan. 
209. Oediceropsis brevicornis, Lilljeborg. 
Af denne ved vore Kyster temmelig sjeldent forekom- 
mende Form toges nogle Exemplarer ved Huso. Hen er 
udenfor Norge kun kjendt fra Bohuslan. 
Fam. 8. Paramphithoidse. 
210. Pleustes panoplus, (Kroyer). 
Denne hoinordiske Form, der ved vore Kyster kun 
undtagelsesvis forekommer udenfor den arktiske Kegion, 
blev under Expeditionen observeret i Havnen ved Reikjavik, 
paa flere Punkter ved Spitsbergen og paa Stat. 359 i Havet 
Vest n,f denne Ggruppe. Arten er nordlig udbredt til 
Gronland, Labrador, Polaroerne og det kariske Hav. 
207. Acanthostepheia Malmgreni, (Goes). 
A few individuals of this characteristic Arctic species 
were taken on the Expedition, off Spitsbergen, where, too, 
it was first met with, by Goes. The northern range ot 
distribution extends to the Barents Sea, Franz Josephs 
Land, the Siberian Polar Sea, and the Kara Sea; but as 
yet, the form has not been observed off the Norwegian coast. 
208. Aceros phyllonyx, (M. Sars). 
Numerous specimens of this form were collected on 
the Expedition in divers localities of the tract of ocean 
we had to traverse and investigate, from depths reaching 
1004 fathoms. Of the Stations, one (Stat. 48) lay in the 
sea east of Iceland, another (Stat. 240) between Iceland 
and Jan Mayen, one (Stat. 273) in the Barents Sea, and 
4 other Stations (Stats. 336, 338, 357, 363) in the sea 
surrounding Spitzbergen. Moreover, the species was ob- 
served in the Saltenfjord, and in the Tanafjord (Stat. 261). 
The form, which occurs along the whole of the Norwegian 
coast, has its northern range of distribution up to Spitz- 
bergen, Franz Josephs Land, and the Kara Sea, and 
southward extends to Bohuslan. 
209. Oediceropsis brevicornis, Lilljeborg. 
Of this form, comparatively rare off the Norwegian 
coast, a few specimens were taken, at Huso. Beyond the 
limits of Norway, the species is unknown, save from Bohuslan. 
Fam. 8. Paramphithoidae. 
210. Pleustes panoplus, (Kroyer). 
This Arctic form, which, on the coast of Norway, is 
of exceptional occurrence beyond the limits of the Arctic 
region, was observed on the Expedition in the harbour of 
Reikjavik, also throughout several localities off Spitzbergen, 
and at Station 359, in the sea west of that group of islands. The 
species has its northern range of distribution up to Green- 
land, Labrador, the Polar Islands, and the Kara Sea.
