Ai’ten forekommer temmelig hyppig ved vor hole Kyst 
lige til Vads 0 og er sydlig udbredt til Kattegat og de bri- 
tiske 0er ( Anonyx denticulatus Sp. Bate), nordlig til Gron- 
land, Spitsbergen, det kariske Hav og den murmanske 
Kyst. 
153. Aristias tumidus, (Kroyer). 
Nogle faa Exemplarer af denne Form toges under 
Expeditionens sidste Togt i Havet 0st af Beeren Eiland 
(Stat. 275) fra et Dyb af 147 Favne. Stationen tilhorer 
den kolde Area. Arten, der ikke er ualmindelig ved vore 
Kyster og ofte forekommer i Gjellesaekken hos Ascidier, 
synes at have en meget vid geografisk Udbredning, da den 
er noteret fra Bohuslan, de britiske 0er, Middelhavet, 
Gronland, Spitsbergen og Franz Josephs Land. 
154. Cyphocaris anonyx, (Liitken) Boeck. 
Et enkelt Exemplar af denne meget eiendommelige, 
tidligere alene fra Gronland bekjendte Form toges under 
Expeditionens 2det Togt i Havet udenfor Yestfinmarken 
(Stat. 190) fra et Dyb af 870 Favne. 
155. Anonyx nugax, Phipps. 
(= A, lagena , Kroyer), 
Talrige, tildels kjmmpemsessige Exemplarer af denne 
v el bekjendte arktiske Art erholdtes under Expeditionen fra 
den kolde Areas Dyb (Stat. 33, 124, 200, 312) og sydlig 
indtil den 63de Bredegrad; Dybden fra 350 til 658 Favne. 
Desuden observeredes den paa grander© Vand ved Jan 
Mayen, Beeren Eiland og Spitsbergen. 
Ai’ten, der hos os hovedsageligt er indskrsenket til 
den arktiske Region, livor den or meget almindelig, synes 
M have en vid Udbredning i de polare Have, idet den 
foruden paa de ovennmvnte Lokaliteter er noteret fra Is- 
land, Gronland, Labrador, Polarperne, det ochotske Hav, 
Sihiriens Ishav, det kariske Hav, Franz Josephs Land, 
Spitsbergen, den murmanske Kyst og det hvide Hav. 
The species occurs with comparative frequence along the 
whole Norwegian coast, as far north as Y ads0 ; southward, 
it is distributed to the Cattegat and the British Islands 
(. Anonyx denticulatus Sp. Bate); northward, to Greenland, 
Spitzbergen, the Kara Sea, and the Murman coast. 
153. Aristias tumidus, (Kroyer). 
A few specimens of this form were taken on the last 
cruise of the Expedition, in the sea stretching east of 
Beeren Eiland (Stat. 275), at a depth of 147 fathoms. 
The Station belonged to the cold area. This species, not 
uncommon off the Norwegian coast, and which often occurs 
in the branchial sac of Ascidians, would appear to have 
a very extensive geographical distribution, being recorded 
from Bohuslan, the British Islands, the Mediterranean, 
Greenland, Spitzbergen, and Franz Joseph’s Land. 
154. Cyphocaris anonyx, (Liitken) Boeck. 
A solo specimen of this very peculiar form, till then 
known from Greenland only, was taken on the 2nd cruise 
of the Expedition, off West Finmark (Stat. 190), at a 
depth of 870 fathoms. 
155. Anonyx nugax, Phipps. 
(= A. lagena , Kroyer). 
Numerous — part of them truly colossal — specimens 
of this well-known Arctic form, were brought up on the Ex- 
pedition from the depths of the cold area (Stats. 33, 124, 
200, 312) and, southward, as far as the 63rd parallel of 
latitude; depth ranging from 350 to 658 fathoms. More- 
over, the animal was observed, in shallow water, oft Jan 
Mayen, Beeren Eiland, and Spitzbergen. 
The species, whose habitat in Norway is chiefly limited 
to the Arctic region, where it occurs with very considerable 
frequence, would appear to be widely distributed throughout 
the Polar Seas, since, apart from the above-mentioned lo- 
calities, the animal is known from Iceland, Greenland, La- 
brador, the Polar Islands, the Sea of Ochotsk, the Siberian 
Polar Sea, the Kara Sea, Franz Joseph’s Land, Spitz- 
bergen, the Murman coast, and the White Sea.
