from Storeggen.

(= A. hetcrodon, Leach). 
Et enkelt, men vel vedligeholdt Exemplar af denne 
ved vore Kyster overordentlig skjeldne Krabbe toges sam- 
men med foregaaende. 
Den er almindelig ved de britiske 0er og gaar sydlig 
td Middelhavet (Adriaterhavet), men er hidtil ved vore 
Kyster kun observeret paa en eneste Localitet, nemlig ved 
Ohristiansund. 
Trib. 2. Oxyrhyncha. 
Fam. Majidae. 
3. Hyas araneus, Lin. 
Denne ved vore Kyster meget almindelige Art obser- 
\eredes under Expeditionen ogsaa ved Beeren Eiland, Is- 
land og Spitsbergen. Paa forstnmvnte Localitet erlioldtes 
et Exemplar af den samme eiendommelige Yarietet, som 
af Hoeck 1 er henfort til folgende Art, men som utvivlsomt 
gaar naermcst ind under H. araneus. 
I sin Udbredning er den en aegte arktisk og circum- 
polar Form, der foruden paa de omtalte Localiteter er 
observeret ved Gronland, Nordamerikas 0stkyst, Berings- 
havet, det ochotske Hav, det sibiriske Ishav, det kariske 
Hav og det hvide Hav. Sydgrmndsen for dens Udbredning 
ved Europas Kyster synes at vsere Nordvestkysten af 
Frankrige.

2. Atelecyclus septemdentatus, Montgy. 
(= A. heterodon, Leach). 
A sole example — but in good condition — of this crab, 
remarkably rare off the coast of Norway, was taken along 
with the preceding. 
The species is common on the shores of Great Britain, 
and its range of distribution extends as far south as the 
Mediterranean (the Adriatic Sea), but has hitherto been 
observed off the Norwegian coasts in one locality only — 
near Ohristiansund. 
Trib. 2. Oxyrhyncha. 
Fam. Majidae. 
3. Hyas araneus, Lin. 
This species, a very common one off the coasts of 
Norway, was observed on the Expedition also off Beeren 
Eiland, Iceland, and Spitsbergen. In the first-named of 
these localities, we took a specimen of the peculiar variety 
that Hoeck 1 has referred to the next species, but which 
unquestionably is most nearly related to H. araneus. 
In its distribution, this is a true Arctic and circum- 
polar form, that, apart from the aforesaid localities, has 
been observed off Greenland, the east coast of North 
America, Bering’s Sea, the Sea of Ochotsk, the Siberian 
Polar Sea, the Kara Sea, and the White Sea. The southern 
limit of distribution on the coasts of Europe would appear 
to be the north-western shore of France.
