Udbredelse 



Denne Art forekommer mere eller mindre talrig 

 langs hele Kysten fra Christianiafjorden til Varangerfjorden; 

 i største Mængde optræder den ved Nordlands og Fin- 

 markens Kyster, 10 — 50 Fv. (M. Sårs), dog kan den ogsaa 

 i det sydlige Norge være meget almindelig, saaledes fandt 

 Professor G. 0. Sårs den i enorme Masser paa Stor- 

 eggen, 10U Fv. 



Udenfor Norge kjendes Ophioglypha robusta fra Kara- 

 havet, 40—50 Fv. (Stuxberg); Vestkysten af Novaja 

 Semlja, 85 Fv. (Marenzeller); Barentshavet (Hoffmann); 

 Spitsbergen. Jan Mayen, 12^2 — 90 Fv. (Fischer); Island, 

 Færøerne, Shetlandsoerne, Østkysten af Skotland og det 

 nordlige England (Norman); Skagen og Hirshals, 52 — 80 

 Fv. (Mobius & Biitschli); Kattegat, 11—45 Fv. (Petersen); 

 Store Belt, 25 Fv. (Mobius & Biitschli); Øresund 10—18 

 Fv. (Liitken); Kullen, Skåne (Lilljeborg); Bohusliin (Loven); 

 Grønland (Liitken. Duncan & Sladen); den nordlige og øst- 

 lige Kyst af Nordamerika indtil Cape God (Lyman). 

 Ligesom Ophioglypha sarsii tilhører saaledes ogsaa Ophio- 

 glypha robusta saavel den kolde som den varme Area, 

 talrigt synes den at optræde paa Grændsen inellem begge 

 Zoner.

Localities. 



Station Husoen, 20 — 100 fath. A few specimens. 



— No. 26 1 specimen. 



, 257, 30— 40 fath. Quite general. 



Distribution. 



This species appears more or less abundantly along 

 the entire coast from the Christiania fiord to the Varanger 

 fiord; it appears in the greatest quantity on the coasts 

 of Nordland and Finmark, 10 — 50 fath. (M. Sårs) but it 

 can also be very common in southern Norway; it was, 

 for instance, met with in enormous quantities on Stor- 

 eggen, 100 fath., by Professor G. 0. Sårs. 



Beyond Norway Ophioglypha robusta is known from 

 the Kara Sea, 40 — 50 fath. (Stuxberg); the west coast of 

 Nova Zembla, 85 fath. (Marenzeller) ; the Barents Sea 

 (Hoffmann); Spitzbergen, Jan Mayen, 12y 2 — 90 fath. 

 (Fischer) ; Iceland, the Faroe Islands, the Shetland Is- 

 lands, the east coast of Scotland and the north of England 

 (Norman); Skagen and Hirshals, 52 — 80 fath. (Mobius & 

 Biitschli); Oresund, 10 — 18 fath. (Liitken); Kullin, Skåne 

 (Lilljeborg); Bohuslen (Loven); Greenland (Liitken, Duncan 

 & Sladen) ; the northern and eastern coasts of North 

 America, as far as Cape God, (Lyman). Just as Ophio- 

 glypha sarsii, so does Ophioglypha robusta belong to both 

 the cold area as well as the warm area. It seems to ap- 

 pear most abundantly on the boundary between both zones.
