varietet, der synes at være den paaSpil bergen, eller idet- 

 hele i det rent arctåske G-ebet hyppigst optrædende Form 

 af Arten, er næsten ensfarvet uden større Pletter riler 

 Striber. Bondfaxven, sum er graagul. er næsten skjult af 

 yderst fine, fcætstillede, brune Punkter; Ims de yngre ere 

 diss,, isser udbredte over Finnerne og paa Legemets Sider. 

 som derved erholde en brunb'g Aiskygnmg, ligesom hist og 

 her, saaledes som paa Bugen, Bundfarven kan optræde

Det 4de Individ, der er det største, Og noget defect. 

 idet Huden tildels er atrevet. ligesom Caudalen mangler, 

 har jeg i min foreløbige Oversigtl troet at burde benføre 

 under L. tunieatus, Reinh., væsentlig paa Grund af. et 

 større Straaleantal i Analen og Pectoralen, samt den sidst- 

 nævnte Finnes betydelige Længde, idet Spidsén naar lidt 

 forbi Begyndelsen af" Analen. ' Sandsynligvis udgjør det 

 dog blot et Stort Individ at' L. lineatus, og gaar blandt de 

 i den ovenfor anførte Afhandling nævnte Varieteter nananest 

 •ind under var. r. subfuscus. Af denne Varietet har Uni- 

 versitets-Musæet allerede tiere mindre Exeinplarer fra Var- 

 angerfjorden i Norge. 



Dette sidstnævnte Individ, der var en Hun med et 

 overordentlig stort Anta] fine Rogn i Ovarierne, havde føl- 

 gende Maal: Totall. 122"" (omtr.); Hovedets Længde 

 33 . Straaleantallet var: D. 42. A. 38. P. 39—42. 



Bundfarven, der er lysl graagul, er omtrent ligesaa 

 stærkt fremtrædende, som de smaa uregelmæssige Pletter 

 (under en Orbitaldiameters Størrelse), der er jevnt fordelte 

 over den. Hist og her ere Pletterne lidt sammenhængende, 

 uden dog at danne Linier; de horizontale Finner ere der- 

 imod stribede paa tvers. Huden er overordentlig lost ved- 

 hængende, skjønt Individet var vel conserveret. 



Paa Gjællerne af dette Individ snyltede et Exemplar 

 af en stor Lernæide (sandsynligvis Eaæmobaphes cyclop- 

 terina, Pabr.). 



Føde. Ventrikeleti af det ene Individ fandtes fyldt 

 med smaa Crustaceer, nemlig en CapreUa septemtrionalis, 

 Kr., samt flere Individer af Protomedeia fasciata, Kr.: den 

 sidste Amphjpode fandtes ligeledes hos et af de unge Indi- 

 vider. I Ventrikelen af det største Individ fandtes Dele 

 'af en større Annelide. Pedinaria auricoma, (Mull.). 



Spitzhergcn and throughout the Arctic regions generally 



than any other form of the species, is of an almost uniform 

 colour, exhibiting no vestige of large spots or stripes. The 

 ground-colour, greyish-yellow, nearly concealed by a mul- 

 titude ol' closely disposed minute brown specks: in com- 

 paratively young individuals these minute spots are dis- 

 persed in particular over the tins and along the lateral 



region of the body, which they blur with a brownish tinge ; 

 and here and there, too, -as on the abdominal surface, 



the ground-colour occurs unitornih spotless.

The fourth specimen is much the largest, but some- 

 what mutilated, portions of the skin having been torn off: 

 the caudal, too. is wanting; in my preliminary report 1 

 I have referred it to L. tunicatus, Reinh.. chiefly 

 by reason of the greater number of tin-rays in the 

 anal and the pectorals, and from the very considerable 

 length of the latter tin, the points of which extend a • 

 short distance ] tst the origin of the ami. Probably, how- 

 ever, this specimen was merely a large-sized individual of 

 L. lineatus, and should in that case rank under var. C, 

 svhfuscus, mentioned in the paper cited above. Of this 

 variety the University Museum is already in possession of 

 several smaller specimens from the Varanger Fjord. 



This, the last of the individuals. ;i female, having 

 in the ovaries large quantities of minute ova. measured 



as follows: — Total length 122 ' (about); length of 



head 33 : number of fin-rays: — D. 42: A. 38; P. 



oil— 42. 



The ground-colour, a uniform light greyish-yellow, 

 and the small irregularly disposed spots (somewhat less in 

 diameter than the length of the orbit) cover about an equal 

 extent of surface. In places, the spots exhibit a tendency 

 to approximate, without however forming lines; the 

 horizontal tins, on the other hand, are distinctly marked 

 with transverse stripes. The skin is remarkably lax. not- 

 withstanding the individual was in all respects a well-pre- 

 served specimen. 



On the gills of this individual occurred a large 

 example of a Lernæan parasite (possibly Hoemoba/phes 

 ii/i-ltijitrf/iitt. Kahr.). 



Food. — The stomach of this one specimen was 

 found distended with small crustaceans, viz. a CapreUa 

 septemtrionalis, Kr.. and divers examples id' Protomedeia 

 fasciata. Kr.: the latter Amphipod was likewise detected in 

 the ventricle of one of the young specimens. The stomach 

 of the largest individual contained fragments of a large 

 Annelid. Pedinaria auricoma, (MM.).
