Et vel vedligeholdt Exemplar af denne Art blev under 

 Expeditionens sidste Togt tåget i Havet Ost af Vardo (Stat. 

 262) fra et Dyb af 148 Favne, og et andet Exemplar er- 

 holdtes under den hollandske Expedition ligeledes i Øst- 

 havet. Jeg har tidligere observeret samme Art paa Stor- 

 eggen, men feilagtigt identificeret den med C. Cranchii 

 Leach. Artens Identitet med den nordamerikanske Form 

 har jeg kunnet overbevise mig om ved direkte Sammenlig- 

 ning med et Exemplar tilsendt vort Museum fra Prof. 

 Sidn. Smith.

 land, Sibiriens Ishav, det kariske Hav og Franz Josephs 

 Land og blev under den hollandske Expedition tåget paa 

 flere Punkter i den saakaldte Barents-Sø (Østhavet). Ved

An individual of this form, in a good state of preserva- 

 tion, was tåken, on the last cruise of the Expedition, in the 

 sea east of Vardo (Stat. 262), at a depth of 148 fathoms, and 

 a specimen was likewise obtained on the Dutch Expedition, 

 also in the Barents Sea. I had previously observed the 

 same specics on the Storeggen Bank. but confounded it 

 with C. Cranchii, Leach. The identity of the species with 

 the North American form, I have had opportunity of sub- 

 stantiating by direct comparison, a specimen of the latter 

 ha ving been kindly presented to the Christiania Zoological 

 Museum by Professor Sidney Smith.

 The species is distributed as far north as Greenland, the 

 Siberian Polar Sea, the Kara Sea. aud Franz Joseph's
