This sjjeeies has a circiimpolar distribution. It oocurs 

 on neaiiy all the coasts of the Arctic Ocean, but it seems to 

 be most abimdant in the sliallow Sil)erian Sea, where Stux- 

 BERG, daring tJie famous Vega Expedition, found it to equal 

 Atijlns carinatiis, Glyptonotiis cntonion and Gl. Sahini in the 

 great number of its speeimens. Farther sonth it is not at all 

 rare in the North Atlantic, the North Sea, and the Baltic 

 as far east as the East coast of Gotland and the entrance of 

 the Bay of Finland. 



It lives mainl^^ on mnddy bottom and in moderate depths 

 from 10 up to 500 fathoms. It is very seldom ol)tained in 

 the abyssal regions. During the Norwegian North Atlantic 

 Expedition it was trawled once from 619 fath. {— 1187 m.), 

 the greatest depth from which it is obtained as far as I know. 

 What Hansex means, when he says ^ »fraregnet Normaxs 

 ovenfor citerede Skrabning paa 1750 Fv.>, I cannot under- 

 stand; it must result from an error. Normax's station, Valor- 

 ous Exp. no. 4, was in 60 fath.
