(1837), og at begge udgjøre rie næsten udvoxede Individer 

 af Fries' Clinus nebulosus fra Bohuslen (1837). har jeg i 

 den ovennævnte Afhandling (Norges Fiske) tidligere søgt 

 at begrunde; og det kan neppe være nogen Tvivl under- 

 kastet (hvad allerede Nilsson i 1855 har antydet), at den 

 ligeledes er identisk med Beinhardts ovenfor nævnte Lum- 

 penus i ( linus) gracilis fra Grønland, der omtaltes første Gang 

 i 1838. Vistnok berøres denne af Reinhardt blot med 

 nogle faa Ord; men Kroyer har senere (i 1862) givet en 

 detailleret Beskrivelse af denne Form. der sees at have 

 været et stort Individ med en Totallængde af omtr. 340""", 

 og dette er i alle væsentlige Henseender overensstemmende 

 med ligestore Individer fra de norske Kyster, saavel i den 

 ydre, sum den indre Bygning. 



Foruden de Beskrivelser, der ere fremkomne gjennem 

 Kroyer, Nilsson og Fries, haves allerede fra 1838 en sær- 

 deles udførlig saadaii. forfattet af Stuwitz i Nyt Mag. f. 

 Naturv., 1 B.. hvori et næsten udvoxet Individ med en 

 Totall. af omtr. 265 fondet tilligemed et Par andre lig- 

 nende i Christianiafjorden i 1835 og 1836 af Prof. Esmark, 

 beskrives med den yderste Nøjagtighed. Der er saaledes 

 ingen Mangel paa Beskrivelser af denne Art. men da de 

 alle ere indbyrdes mere eller mindre uoverensstemmende. 

 alt eiter Storrelsen og de ydre Variationer hos de fore- 

 liggende Individer, har jeg troet det ikke overflødigt her 

 at lade folge en ny og mere kortfattet, hvor der saavidt 

 muligt er tåget Hensyn til alle disse individuelle Uoverens- 

 stemmelser. 



Exeinplaret fra Magdalenebay havde en Totallængde 



af 62""". hvoraf Hovedets Længde udgjorde lo.:, Det 



var saaledes (ligesom Exemplaret fra Rost i Lofoten) blot 

 en Unge. og svarede fuldkommen .til Unger af samme Stør- 

 relse fra de norske Kyster. 



Beskrivelse. Legemsbygning. Sammenlignet med de 



øvrige Arter er Legemet forholdsvis langstrakt, især hos 

 de ældre Individer. Ligeledes er Hovedet betydeligt min- 

 dre hos de ældre, end hos de yngre Individer, og hos ingen 

 anden Art er den gradvise Forandring i denne Henseende 

 saa betydelig. 



Hojden over Nakken indeholdes hos de yngre Indi- 

 vider (omkr. 60 — 70 i omtr. 12 Gange i Totallængden, 



hos de ældre lige til 20 Gange og derover: bagenfor Nak- 

 ken bliver Legemets Højde nbetydeligt større, men inde- 

 holdes dog endnu hos et større Individ (Totall. 265""") 2<) 

 Gange i Totallængden. 



Hovedet er forholdsvis lidet; dets Forhold til Totall. 

 varierer fra 5 1 / a lige til 10 og derover. Saaledes indeholdes

Norway (1*37). and that both represent the nearly full- 

 grown examples of Fries's Clinus nebulosus, from Bohuslen 

 (1837). I have sought to show in the treatise cited above 

 ("Norges Fiske"): nor does there (as suggested by Nilsson 

 in 1855) exist any valid reason for questioning its identity 

 with Reinhardts Lwnpenus (Clinus) gracilis, from Green- 

 land, mentioned for the first time in 1838. True. Rein- 

 hardt alludes to the species in a few words only; but a. 

 detailed description was furnished by Kroyer (in 1862) 

 of this form; and the diagnosis of the specimen examined, 

 a large individual, total length about 340""". corresponds 

 in all essential particulars precisely with that of individuals 

 of equal size from the coast of Norway, both as regards 

 its outer and inner structure. 



Exclusive of the diagnoses by Kroyer, Nilsson, and 

 Fries, an elaborate description was furnished by Stuwitz. 

 as far back as 1838. and published in "Nyt Mag. f. Na- 

 turv.", I B.. in which an individual, almost mature (total 

 length about 265"""). found, together with one or two other 

 examples of the same species, in the Christiania Fjord, in 

 1835 and 1836. by Prof. Esmark. is described with the 

 greatest accuracy. There is accordingly no want of de- 

 scriptions of this species; but all of them being, when com- 

 pared together, more or less divergent, from the difference 

 in size and external features generally characterising the 

 specimens examined, 1 have not deemed it superfluous to 

 annex a new and more compendious description, in which. 

 so fir as possible, regard has been had to these individual 

 incongruities. 



The example from Magdalene Bay had a total length 

 of 62""". the length of the head being 10.5 This spec- 

 imen (like' the example taken off Rost. in Lofoten) was 

 accordingly a young individual, corresponding exactly with 

 young individuals of equal size from the coast of Norway. 



General Description. Structure <>j tin' Body. — 

 Compared with the other species, body rather elongated, 

 more especially in mature examples. The head, too, con- 

 siderably .smaller in adults than in young individuals; and 

 in none of the "other species are the gradations during 

 growth so considerable. 



Depth of body at nape, in young individuals (60 — 70"""), 

 bears to total length the proportion of 1 to 12; in mature 

 examples, of 1 to 20. and above; posterior to the nape, the 

 depth of the body exhibits a slight increase, being never- 

 theless to total length, in a comparatively large-sized indi- 

 vidual (total length 265"""). as 1 to 20. 



Head comparatively small, its proportion to total 

 length varying from that of 1 to b l j 2 to 1 to 10, and above. 

 The length of the head, accordingly, in the several speci- 

 mens, was to the total length as follows: —
