(1837), og at bfggc udgjore de næsteu lulvoxede Individer 

 af Fries' CHinus nehulosus fra Bohuslen (1837), har- jeg i 

 den ovennævnte Afliandling (Norges Fiske) tidligere søgt 

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

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

 ligeledes er identisk med Reinhardts ovenfor nævnte Lum- 

 pemis (Clinus) gracilis fr-a 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 TotaUængde af omtr. 340 "", 

 og dette er i alle væsentlige Henseender overensstemmende 

 med ligestore Individer fra de norske Kyster, saavel i den 

 ydre, som den indre Bygning. 



Foruden de Beskrivelser, der ere fremkomne gjenuem 

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

 deles udførlig saada.n. forfattet af Stuwitz i Nyt Mag. f. 

 Naturv.. 1 B.. hvori et na^sten udvoxet Individ med en 

 Totall. af omtr. 265'"'". fuudet tilligemed et Par andre lig- 

 nende i Christianiaf jorden 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 efter Størrelsen og de ydre Yariationer hos de fore- 

 liggende Individer, har jeg troet det ikke overtiodigt her 

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

 muligt er tåget Hensyn til alle disse individuelle Uoverens- 

 stemmelser. 



Exemplaret fr-a Magdaleuebay havde en TotaUængde 

 af 62'"'". hvoraf Hovedets Længde udgjorde 10.5 "'"• 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. Legemshygning. 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 jnigre Individer, og hos ingen 

 anden Art er den gi-advise Forandring i denne Henseende 

 saa betydelig. 



Højden over Nakken indeholdes hos de yngre Indi- 

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

 hos de ældi-e lige til 20 Gange og derover; bagenfor Nak- 

 ken bliver Legemets Hojde ubetydehgt større, men inde- 

 holdes dog endnu hos et større Individ (Totall. 265'"'") 20 

 Gange i Totallængden. 



Hovedet er forholdsvis lidet; dets Forhold til Totall. 

 varierer fra 5^/3 hge til Hl og derover. Saaledes indeholdes 

 Hovedlængden i Totallængden hos de forskjellige Individer 

 efter følgende Forholde : 

 TotaUængde 50"'"'; Hovedets Forhold til Totall.

Norway (1837). and that both represent the nearly full- 

 grown examples of Fries's Clinus nehulosus, 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 Reinhardt's Lxvqjeniis (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 tills form: and the diagnosis of the specimen examined, 

 a lax'ge 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."', 1 B.. in which an individual, almost mature (total 

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

 examjjles of tlie same species, in tbe 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. I have not deemed it sujierfluous to 

 annex a new and more compendious description, in which, 

 so far as possible, regard has been had to these indi\1dual 

 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 Røst. in Lofoten) was 

 accordingly a young individual, corresponding exactly with 

 young individuals of equal size from the coast of Norway. 



General Description. Shitdure of fhe Bodg. — 

 Compared with the other species, body rather elongated, 

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

 siderably smaller in adults than in young inchviduals; and 

 in none of the otlier species are the gradations during 

 growth so considerable. 



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

 bears to total length the j^roportion 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 tb 20. 



Head comparatively small, its proportion to total 

 lenffth varvinjj from that of 1 to 5\.> to 1 to 10. and above. 



/-' 



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

 mens, was to the total length as follows: — 



Total length 50"'"'; length of head to total length 5.5
