Angmagsalik. Species as Rose-fish (Sebasfes marinus L.) and 

 the Cod [Gadus caUarias L.) which are only exceptionally found 

 in Polar water are likewise only known from Angmagsalik, and 

 south of this place. Where trawling has been done farther 

 north at corresponding depths only pure Cold-water species 

 have been caught (as Lycodes eudipleurostictus Jensen, and 

 L. pallidus Coll.) or species which thrive in sea water of both 

 positive (low) and negative degree (as Cottunculus microps Coll., 

 and Liparis (Careproctus) reinhardti Kr.). 



The shallow-water fish-fauna as far as can be judged at 

 present, is arctic, and as will be seen by the list the same species 

 are for Ihe greater part met with all along the long coast-line. 

 Cottus quadricornis L. forms however a remarkable exception. 

 It is plentiful enough from Turner Sund and farther north but 

 is not found at Angmagsalik. The circumstance that this high- 

 arctic fish ^) is not found at the southern coast is interesting 

 considered f. i. in connection with the fact that an equally 

 strongly marked high -arc tic species among the Mollusca viz. 

 Yoldia (Portlandia) arctica Gray (which lives together with 

 C. quadricornis in Turner Sund and farther north) is also missing 

 at the southern part of the coast. On the other hand there is 

 among the Mollusca a boreo-arctic species which thrives 

 admirably at Angmagsalik, but does not appear farther north, 

 viz. the common Mussel [Mytilus edulis L.). I do not therefore 

 consider it quite improbable that when the southern coast gets 



M At West-Greenland it does not go farther south than Baffin Bay; else 

 it lives at the Arctic America, in the ley sea of Siberia, and in the White- 

 Sea (and in the inner part of the Baltic, and some lai'ge lakes con- 

 nected with this sea, -where it is considered as a relict-species from the 

 Glacial-period). It has been found farther north than any other fish viz. 

 at 82'/2° lat. N. (Dumb-bell harbour at Grinnell-Land). — It is not un- 

 known to me that writers as Francis Day maintain its distribution at 

 the British Islands, but I feel convinced that these accounts are based on 

 some mistakes. I also consider as wrongly determined the young ones 

 which have lately been described and figured by English biologists as 

 young ones of i< С quadricornis« .
