Nymphon mixtum KröYER.

Recent authors seem inclined to unite the two last men- 

 tioned species to one which then carries the first name. I can- 

 not form myself any certain opinion about this on the material 

 on hand because these comparatively few specimens may each 

 easily be referred to one of either species by using the charac- 

 teristics mentioned by Särs. 



If both forms are counted together which must be done 

 now when the geographica! distribution is discassed, because låter 

 authors have done so, N. grossipes in its wider sense seems to 

 extend all över the Northern Atlantic from the coasts of Eng- 

 land and the Sound northwards, and in the Arctic from the 

 Kära Sea (1) to East Greenland (4, 7), and from West Green- 

 land down the North American Westcoast.

This species originally established on specimens from Bar- 

 ents Sea has afterwards been stated to live in the Kära Sea 

 whence it has been collected by the Vega and Djimphna expedi- 

 tions (1, 2). The Norwegian North- Atlantic expedition found it 

 between Norway and Beeren Eiland, and the Danish Ingolf
