109. Cirolana borealis, Lilljeborg. 
Kun observeret under Expeditionen paa Stat. 79 i 
Havet udenfor vor Yestkyst; Dybden 155 Favne. Arten 
forekommer foruden ved vore Kyster ved de britiske 0er 
( C . spinipes Bate) og i Kattegat. 
110- Cirolona concharum, (Stimpson). 
(= O. Cranchii, Gr. 0. Sars, non Mont. 
= 0. microphthalma, Hoeok). 
Et vel vedligeholdt Exemplar af denne Art blev under 
Expeditionens sidste Togt taget i Havet 0st af V ard© (Stat. 
262) fra et Dyb af 148 Favne, og et andet Exemplar er- 
holdtes under den hollandske Expedition ligeledes i 0st- 
havet. Jog har tidligere observeret samme Art paa Stor- 
eggen, men feilagtigt identifieeret den med C. Cranchii 
Leach. Artens Identitet med den nordamerikanske Foim 
har jeg kunnet overbevise mig oin ved direkte Sammenlig- 
ning med et Exemplar tilsondt vort Museum fra Prof. 
Sidn. Smith.

Et enkelt mindre Exemplar af denne hoinordiske Form 
evholdtes under Expeditionens sidste Togt i 0sthavet (Stat. 
273) fra et Dyb af 197 Favne. Arten or udbredt til Gron- 
hmd, Sibiriens Ishav, det kariske Hav og Franz Josephs 
Land og blev under den hollandske Expedition taget paa 
Sere Punkter i den saakaldte Barents-So (0sthavet). Yed 
vore Kyster er den endnu ikke bleven iagttaget.

109. Cirolana borealis, Lilljeborg. 
On the Expedition, observed at Station 79 alone, in 
the sea off the West Coast of Norway; depth 155 fathoms. 
Apart from the Norwegian coast, the species occurs off the 
British Islands (C. spinipes Bate) and in the Cattegat. 
110. Cirolana concharum, (Stimpson). 
(= C. Crancldi , Ct. 0. Sars, non Mont. 
= C. microphthalma, Hoeck). 
An individual of this form, in a good state of preserva- 
tion, was taken, 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 species 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 
having been kindly presented to the Christiania Zoological 
Museum by Professor Sidney Smith.

III. Glyptonotus Sabini, (Kroyer). 
A sole and not yet full-grown specimen of this Arctic 
form, was obtained, on the last cruise of the Expedition, in 
the Barents Sea (Stat. 273), from a depth of 197 fathoms. 
The species is distributed as far north as Greenland, the 
Siberian Polar Sea, the Kara Sea, and Franz Joseph’s 
Land. On the Dutch Expedition, it was taken in several 
localities throughout the Barents Sea. Off the Norwegian 
coast, it has not yet been observed.
