Arten forekommer temmelig hyppig ved vor hele Kyst 

 lige til Vadsø og er sydlig udbredt til Kattegat og de bri- 

 tiske- Øer (Anonyx denticulatus Sp. Bate), nordlig til Grøn- 

 land, Spitsbergen, det kariske Huv og den murmanske 



Kvst, 



153. Aristias tumidus, (Kroyer). 



Nogle faa Exemplarer af denne Form toges under 

 Expeditionens ^idste Togt i Havet Øst af Beeren Eiland 

 (Stat. 275) fra et Dyb af U7 Favne. Stationen tilhører 

 den kolde Area. Arten, der ikke er ualmindelig ved vore 

 Kyster og ofte forekommer i Gjellesækken hos Ascidier, 

 synes at have en meget vid geografisk Udbredning, da den 

 er noteret fra Bohuslån, de britiske Øer. Middelhavet, 

 Grønland, Spitsbergen og Franz Josephs Land. 



154. Cyphocaris anonyx, (Ltitken) Boeck. 



Et enkelt Exemplar af denne meget eiendommelige, 

 tidligere alene fra Grønland bekjendte Form toges under 

 Expeditionens 2det Togt i Havet udenfor Vestfinmarken 

 (Stat. 190) fra et Dyb af 870 Favne. 



155 Anonyx nugax, Phipps. 



(= A. lagena, Kroyer). 



Talrige. tildels kjæmpemæssige Exemplarer af denne 

 vel 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 grundere Vand ved Jan 

 Mayen, Beeren Eiland og Spitsbergen. 



Arten, der hos os hovedsageligt er indskrrenket til 

 den arktiske Region, hvor den er meget almindelig. synes 

 at have en vid Udbredning i de polare Have, idet den 

 foruden paa de ovennævnte Lokaliteter er noteret fra Is- 

 land, Grønland, Labrador, Polaroerne, det ochotske Hav, 

 Sibiriens Ishav, det kariske Hav, Franz Josephs Land, 

 Spitsbergen, den murmanske Kyst og det hvide Hav. 



The speeies occurs with eomparative frequence alongthe 

 whole Norwegian coast, as far north as Vadsø; southward, 

 it is distributed to the Cattegat and the British Islands 

 {Anonyx denticidatus Sp. Bate); northward, to Greenland, 

 Spitzbergen, the Kara Sea. and the Murman coast. 



153. Aristias tumidus, (Kroyer). 



A few specimens of this form were tåken 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 speeies, 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 Bohuslån. the British Islands, the Mediterranean, 

 Greenland, Spitzbergen, and Franz Joseph's Land. 



154. Cyphocaris anonyx, (Ltitken) Boeck. 



A sole specimen of this verv pecnliar form. till then 

 known from Greenland only,* was tåken on the 2nd cruise 

 of tlie Expedition, off West Finmark (Stat. 190), at a 

 depth of 870 fathoms. 



!55. Anonyx nugax. Phipps. 



(= .-1. 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, off Jan 

 Mayen, Beeren Eiland. and Spitzbergen. 



The speeies. w hose habitat in Norway is chiefly limited 

 to the Arctic region, where it occurs with very considerable 

 frequence, would appear to be widely distributed thronghout 

 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. aud the White Sea.
