Observeret under Expeditionen ved Jan Mayen paa 
forholdsvis grundt Yand. Arten er almindelig ved Ein- 
marken, sjeldnere ved vor Vestkyst og sydlig udbredt til 
Kattegat og de britiske 0er. 
278. Unciola irrorata, (Say). 
(= Glauconomc Icucopis, Kroyer). 
Talrige Exemplarer af denne characteristiske arktiske 
Form blev under Expeditionen indsamlede paa 7 forskjel- 
lige Stationer. Kim en af disse (Stat. 260) tilhdrer vort 
Kystgebet (Porsangerfjorden). Af de ovvige ligger de 4 
(Stat. 18, 31, 33 og 124) i Havet udenfor vor Vestkyst, 
en (Stat. 267) i Gsthavet og en anden (Stat. 336) udenfor 
Sydpynten af Spitsbergen. Naar undtages denne sidste, 
tilliorer alle de ovrige den kolde Area; Dybden fra 148 
til 525 Favne. 
Arten er ved vore Kyster alene indskrsenket til den 
arktiske Kegion og bar en fuldkommen circumpolar Udbred- 
ning, idet den er noteret fra Spitsbergen, Grpnland, Nord- 
amerikas 0stkyst, det kariske Hav og 0sthavet.

Fain. 18. Corophiidse. 
277. Corophium crassicorne, Bruzelius. 
On the Expedition, observed off Jan Mayen, in com- 
paratively shallow water. The species is common off Fin- 
mark, less frequent along the West Coast af Norway, and 
occurs as far south as the Cattegat and the British Islands. 
278. Unciola irrorata, (Say). 
(= Glauconomc leucopis, Kroyer). 
Numerous specimens of this characteristic Arctic form 
were collected on the Expedition, at 7 different Stations. 
Only one of these (Stat. 260, in the Porsangerfjord), was 
located within the limits of the Norwegian coastal region. 
Of the rest, 4 (Stats. 18, 31, 33, and 124) lay in the sea 
off the West Coast of Norway, 1 (Stat. 267) in the Barents 
Sea, and 1 (Stat. 336) off the southern extremity of Spitz- 
bergen. Excluding the last, all the others were in the 
cold area; depth ranging from 148 to 525 fathoms. 
Off the Norwegian coast, the species is exclusively 
limited to the Arctic region, and has a true circumpolar 
distribution, having been recorded from Spitzbergen, Green- 
land, the east coast of North America, the Kara Sea, and 
the Barents Sea.
