Udbredelse. I Europa forekommer denne Art omtrent 

 uforandret fra Kanalen (48" N. B.) og Østersøen af, og 

 langs Frankrigs. Storbritanniens. Danmarks. Færøernes. 

 Norges og Sveriges Kyster lige op i Østersøen. fremdeles 

 ved Nord-Rusland. Novaja Zemlja, Beeren Eiland og Spits- 

 bergen, hvor den paa flere Stater hører til de hypjtigst 

 forekommende littorale Fiske. Fremdeles er den mere eller 

 mindre talrig ved Islands. Grønlands og det arctiske Ame- 

 kas Kyster; dog ere de Former, der bebo disse Landsdele, 

 af forskjellige Forfattere blevne udskilte under særegne 

 Navne, hvoraf det tidligste er C. groenlandicus, opstillet i 

 1829 af Cuv. og Val. effcer den af Fabr. i lians Fauna 

 Groenl. meddelte Beskrivelse. Disse Arter ere dog af 

 Malmgren 1 , Liitken- o. fl. henviste til Synonymerues Række, 

 idet de samtlige gaa ind under den nævnte vestlig-arctiske 

 Form af denne Art, C. groenlandicus, der maaske vil med 

 nogen Ret kunne opføres som eu constant Varietet af den 

 normale C. scorvius. 



Ved Nordamerikas Kyster rindes, foruden den nævnte 

 østlige Varietet, der er særdeles talrig, ogsaa Hovedarten. 

 Den førstnævnte gaar ued til Cap Hatteras under 36° N. 

 B. ; Hovedarten er fundet. ifolge Goode & Bean (Bull. Ess. ' 

 Inst. vol. XI, 1879) ved New Englands Kyster (Maine), 

 under 44" N. B.

Distribution. — In Europe the range of this species, 

 as an almost constant form, extends from the British Chan- 

 nel (lat. 48" N.) along the coast of France, the entire coast 

 of Great Britain, the coast of Denmark, the Faroe Islands, 

 the coasts of Norway and Sweden, the shores of northern 

 Russia, Novaja Zemlia, Beeren Eiland, and Spitsbergen, 

 where it occurs, in divers localities, as one of the com- 

 monest of the littoral fishes. It is abundant, too, more or 

 less, on the coast of Iceland and Greenland, and the Arc- 

 tic shores of North America. The forms inhabiting those 

 regions have, by some authors, been excluded as distinct 

 species, the earliest synonym being C. groenlandicus, Cuv. 

 & Val. 1829, from the description given by Fabricius in 

 his Fauna Grcenlandica. Malmgren 1 , Liitken 2 , however, 

 and other ichthyologists regard these suppositious sjiecies as 

 identical with the aforesaid west Arctic form of the spe- 

 cies, C. groenlandicus, which, perhaps, with some reason may 

 be regarded as a constant variety of the normal C. scorpius. 



On the shores of North America, exclusive of the 

 aforesaid eastern variety, which occurs in great numbers, 

 the principal species is also met with. The range of the 

 former extends as far south as cape Hatteras. in lat. 36° 

 N. ; the principal species, according to Goode and Bean, 

 (Bull. Ess. Inst. Vol. XI, 1879) has been observed on the 

 coast of New England (Maine), in lat. 44" N.
