 Forskjel, at Panden var 3-lappet istedetfor 4-lappet. Bo-

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 Øer og gaar sydlig 

 til Middelhavet (Adriaterhavet), men er hidtil ved vore 

 Kyster kun observeret paa en eneste Localitet, nemlig ved 

 Christiansimd.

3. Hyas araneus, Lin. 



Denne ved vore Kyster meget ahnindelige Art obser- 

 veredes under Expeditionen ogsaa ved Beeren Eiland. Is- 

 land og Spitsbergen. Paa forstnævnte Localitet erholdtes 

 et Exemplar af den samme eiendommelige Varietet, som 

 af Hoeck ' er henført til følgende Art, men som utvivlsomt 

 gaar nærmest ind under H. araneus. 



I sin Udbredning er den en regte arktisk og circum- 

 polar Form, der foruden paa de omtalte Localiteter er 

 observeret ved Grønland, Nordamerikas Østkyst, Berings- 

 havet, det ochotske Hav, det sibiriske Ishav, det kariske 

 Hav og det hvide Hav. Sydgrændsen for dens Udbi - edning 

 ved Europas Kyster synes at være Nordvestkysten af

 2. Atelecyclus septemdentatus, Montgy. 



(= A. hrterodon. Leach). 



A sole example — but in good condition — of this crab, 

 remarkably rare off the coast of Norway, was tåken 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 Christiansimd.

 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 Spitzbergen. 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.
