som ny opstillt'<k* Art er identisk med ilen af ham under 

 Benævnelsen Cyclopicera nigripes opførte Form. Jeg maa 

 imidlertid være uenig med nævnte Forsker, naar han slaar 

 Slægten Ascomyzon sammen med Sl. Årtotrogus Boeck. 

 ThorelFs Slægt Ascomyzon er utvivlsomt identisk med 

 Brady's Slægt Cyclopicera. 



To Exemplarer af denne ved vore Kyster ikke sjel- 

 dent forekommende Form toges under Expeditionen ved 

 Norske Øer (Spitsbergen) mellem Alger. Skjøndt den aaben- 

 bart som de øvrige Medlemmer af Familien maa fore et 

 halvt parasitiskt Liv, er det hidtil ikke lykkets at paavise, 

 paa hvilket Dyr den snylter.

327. Anchorella uncinata, (Mull). 



Adskillige Exemplarer af en Form, som jeg ikke for- 

 maar at skille fra vor almindelige Anchorella uncinata, blev 

 af Hr. Robert Collett fundne fastheftede til Brystfinnerne 

 af Lycodesarter fra Stat. 322. beliggende NV af Beeren 

 Eiland; Dybden 658 Favne. Arten synes at have en meget 

 vid geographisk Udbredning og er bekjendt fra Island, Grøn- 

 land, Nordamerikas Østkyst. Norges. Danmarks og Englands 

 Kyster.

3 Exemplarer af denne ved sine eiendommelige skrue- 

 formigt dreiede Æggetraade let kjendelige Lernæide blev 

 af Hr. Robert Collett fundne, det ene paa en Liparis 

 lincata, de 2 øvrige paa Gadus polaris fra Magdalenebay 

 paa Spitsbergen (Stat. 366). Arten er først beskreven af 

 Fabricius som parasitisk paa Cyclopterus spinosus fra Grøn- 

 land, senere af Steenstrnp ogsaa fundet paa andre grøn- 

 landske Fiske os lieeledes observeret ved Island. 



species I had established as new is identical with the form 

 t 'yclopicera nigripes. described by him under that appellation. 

 Meanwhile, I must be allowed to differ from the said nat- 

 uralist as to the supposed identity of the genus Ascomyzon and 

 the genus Årtotrogus, Boeck. Thorelfs genus, Ascomyzon, is 

 unquestionably identical with Brady's genus Cyclopicera. 



Two specimens of this form, not uncommon along the 

 Norwegian coasts, were tåken on the Expedition off the 

 Norway Islands (Spitzbergen), between Algæ. Though, 

 obviously, it must, in common with the other members 

 of the family. lead a semi-parasitic existence. no observer 

 has hitherto succeeded in determining the animal on 

 Avhich it fixes.

Fam. 1. Lernæopodidæ. 



327. Anchorella uncinata, (Mull). 



Several specimens of a form that I failed to distinguish 

 from the common Anchorella uncinata were found by Mr. 

 Robert Collett, attached to the pectoral fins of certain 

 species of Lycodes, obtained at Station 312, that lay north- 

 west of Beeren Eiland; depth 65S fathoms. The species 

 would appear to have an exceedingly wide geographical dis- 

 tribution. being known from Iceland. Greenland. the east 

 coast of North America, and the coasts of Norway, Den- 

 mark. and Great Britain. 



Fam. 2. Lernæidæ. 



328. Hæmobaphes cyclopterinus, (Fabr.) 



Three specimens of this Lernæidian, easily distingu- 

 ishable by its peculiar screw - shaped egg-threads, were 

 found by Mr. Robert Collett, — one on a Liparis lineata, 

 the 2 others on Gadus polaris, from Magdalena Bay, Spitz- 

 bergen (Stat. 366). The species was first described by 

 Fabricius, as pccurring parasitically on Cyclopterus spinosus, 

 from Greenland, afterwards by Steenstrup, who met with 

 it on Greenland fishes and likewise observed the animal 

 on fishes tåken off the coast of Iceland.
