4. Hyas coarctatus, Leach. 



Denne ligeledes hos os hyppige Form gaar betydelig 

 dybere ned end foregaaende, nemlig mindst til 150 Favne. 

 Den erholdtes under Expeditionen foruden paa flere Punkter 

 af vor Kyst ogsaa paa følgende mere eller mindre langt 

 ud i det aabne Hav beliggende Stationer: 79. 173 b, 261, 

 290 og 326, samt i Magdalenebay paa Spitsbergen; fordet- 

 meste dog kun i yngre Exemplarer. 



Arten er sydlig udbredt til Kattegat og de britiske 

 Øer. nordlig til Grønland, Nordamerikas Østkyst og det 

 hvide Hav. I det ochotske Hav forekommer efter Brandt ' 

 en eiendommelig Varietet (var. ahdacea), som dog rettest 

 tor være at betragte som en egen Art.

Yngre Exemplarer af denne Form toges under Ex- 

 peditionen paa 3 Punkter of vor Kyst. nemlig ved Husø, 

 i Altenfjord og i Tanafjord. 



Den er nordlig udbredt til Grønland (?), Nordamerikas 

 Østkyst og den murmanske Kyst. hvorimod den neppe gaar 

 længere Syd end til Kattegat, de britiske Øer og Belgien, 

 hvilket synes at vise. at den er en oprindelig arktisk Form.

4. Hyas coarctatus, Leach. 



This form, likewise of frequent oecurrence along the 

 Norwegian coast, descends much deeper than the preceding, 

 viz. to at least 150 fathoms. It was tåken on the Ex- 

 pedition — not including several points off the Norwegian 

 eoast — also at the following Stations, more or less far out 

 at sea. viz. — Stats. 79, 173 b, 261. 290, and 326. as 

 also in Magdalena Bay, Spitzbergen; the greater part 

 however were young individuals. 



The species is met with southwards as far as the 

 Cattegat and the British Islands, northward as far as Green- 

 land, the east coast of North America, and the AVhite Sea. 

 In the Sea of Ochotsck occurs, according to Brandt. ' a 

 peculiar variety (var. (tlvtarea),- which, however. would appear 

 to be strictly entitled to specific distinction.

 6. Lithodes maja, Lin. 



Young individuals of this fonn were tåken on the 

 Expedition off the Norwegian coast, in 3 different localities, 

 viz. at Husø. in the Altenfjord, and in the Tanafjord. 



Northward. its distribution reaches as far as Green- 

 land (?), the east coast of North America, and the Murman 

 coast, whereas the animal is liardly met with farther south 

 than the Cattegat, the British Islands, and the coast of 

 Belgium, thus apparently indicating an Arctic origin.
