Peden rmbrifer forekommer p:ia de større dyli langs 

 vor vest- og nordkyst. Ved sydkysten synes den derimod 

 at mangle. Den er endvidere kjendt fra Karahavet. Novaja 

 Semlja, Barentshavet, Sijitsbergen, Færøerne, Island, Grøn- 

 land og Nordanierikas østkyst. Artens udbredelse mod syd 

 kan for tiden ikke med sikkerhed angives, da den hos et 

 flertal af forfattere har været sammenblandet med den 

 nærstaaende af Forbes fra Ægeerhavet beskrevne peden 

 liosliijnsi. Den bathymetriske udbredelse er 30—650 fv. 

 Fossil er den fiinden i Noraie og Ttalien. 



Pedell nxhyifer occurs in the great depths along the 

 west and north coasts of Norway, but ajjpoars, to l)e absent 

 from the south coast. It has also been found in tlie Kara 

 Sea, Novaja Semlja. the Barents Sea, Spitsbergen, the 

 Faroe Isles, Zeeland, Greenland, and on the east coast of 

 North America. Its distribution southwards cannot at 

 present be stated with certaintj, as the majority of writers 

 have confounded it with the nearly-allied Peden hoski/nsi 

 from the Ægean Sea, described by Forbes. Its bathymet- 

 rical distribution is from 30 to 650 fathoras. It is found 

 as a fossil in Norwav and Italv.

While this species does not attain a length of more 

 than 15 mm. on the coast of Norway, specimens from 

 Spitsbergen measured as much as 24 mm. 



Peden græniandicus does not occur on the Norwegian 

 coast south of Tromso. It is furthermore a circumpolar 

 species, kiiown on the Arctic shores of Siberia, in the 

 Kara Sea, Novaja Semlja, Spitsbergen, Franz Josef Land, 

 the White Sea, Jan Mayen, Iceland, Greenland, arctic 

 North America, the Gulf of St. Lawi-ence, and the North 

 Atlantic down to the west of Senegambia. Its bathynie- 

 trical distribution is from 3 to 713 fathoms. It is found 

 as a fossil on Grinnell Land. in Maine, Scotland, Norway 

 northern Russia, and Siberia.

Peden similis foreligger kun fra en lokalitet, Husø,

 .syd- og vestkyst. Nordenfor Lofoten blir den mere sjelden.

 ,'irt til Madeira, Middelhavet, Adriaterhavet og Ægeerhavet.

Peden similis was only found in one loeality, namely 

 Husø, in depths of from 40 to 60 fathoms. It is common 

 in the deep water off the south and west coasts of Norway, 

 It is rarer north of Lofoten, but is found as far north as 

 Vadsø. Soutliwards it extends to Madeira, the Mediter- 

 ranean, the Adriatic, and the Ægean Seas. Its bathy- 

 metrical distribution is from 15 to 703 fathoms. It is 

 found as a fossil in England, Belgium, Italy and Rhodes.
