kort Bue over denne, gaar derpaa i skråa Retning nedover 

 • indtil noget nedenfor Legemets Midtfure, men har omtrent 

 ret over Anus atter naaet op til denne, og lober nu henad 

 denne ud til Halespidsen. Indtil Anus er Antallet af Porer 

 omtrent 35 ; paa Halens bagerste Parti ere Porerne temme- 

 lig utydelige. 



En anden, næsten umærkelig Riekke Porer, der ere 

 hetvdeligt mindre og mere fjerntstaaehde, lober fra Gjælle- 

 tligen bagover noget ovenfor Legemets Midtlinie. Antallet 

 af Porer i denne (dorsale) Sidelinie er indtil Anus blot 

 7 (Reinhardt fandt hos Typ-Exemplaret 11 i denne 

 Linie); senere tabe de sig mellem Skjællene. Ogsaa hos 

 enkelte andre Arter har jeg kunnet se Spor af denne supra- 

 laterale Sidelinie. men paa Grand af Skjælbeklædningens 

 større Udstrækning bos disse mindre tydeligt; sandsynlig vis 

 maa den opfattes som en Fortsættelse af Hovedets Slim- 

 pore-Net, men ikke som nogen egentlig Sidelinie. 



Paa Gjællelaaget lober eudvidere i en Halvkreds en 

 Række Porer, ligesom en kort Række lober tvers over 

 Snudespidsen lige ved Randen.. 



Farven: Farven er ensartet hvidagtig graabrun, uden 

 Pletter og Baand. En utydelig mørkere Stribe lober langs 

 henad Midtlinien. en anden langs den bagre Del af Dor- 

 salens Grand. Paa Hovedet er der et mørkt Parti paa 

 Gjællelaaget hen mod Spidsen. Pectoralerne ere hvid- 

 agtige, ligesom Analen og Hovedets Underside ; Bugen blaa- 

 sort. Randene omkring Anus hvide. Skjællene ere ligeledes.. 

 lysere, end Bundfarven. . 



Udbredelse. Af denne Art har hidtil blot været 

 omtalt det ene. Typ-Exemplaret. nedsendt til Musæet i 

 Kjøbenhavn fra Omenak (Umanak) i Grønland i 1837. Dets 

 Totallængde var omtrent 449 """, hvoraf Hovedets, Længde 

 var, 123°"". Det nye Individ fra Spitsbergens Nordkyst 

 er. som ovenfor nævnt, en Unge. der optoges fra den 

 tempererede Area (Bundtemperatur -)- 1,1 ° C.) fra Ler- 

 bund i August 1878.

Diagn. Særdeles langstrakt. Farven ensartet graa- 

 hnni. Skjælbeklædningen sildigt og wregehnæssigt frembry- 

 ående; Skjællene i fuldt udviklet Stand udbredte over hele. 

 Legemet, medens Hovedet og Nakken, samt Finnerne ere 

 nøgne. Tændeme forholdsvis stærke; Rækken pga Palatin- 

 benene særdeles kort. Legemets Højde indeholdes 20 — 22 l j 2 

 (-lauge i Totallængden. Hovedet er Jiadt med opadvendte 



gill-cover, above which it makes an abrupt bend, passing 

 from thence obliquely , downwards till a little below the 

 mesial furrow of the body, but reaching it again at a 

 point almost straight above the vent, and running along 

 it to the tip of the tail. Number of pores from origin 

 to vent about 35; they are indistinct on the posterior por- 

 tion of the tail. 



Another, almost imperceptible series of pores, consid- 

 erably smaller and farther apart, extends from the branch- 

 ial flap backwards, somewhat above the mesial line of 

 the body. Number of pores in this (dorsal) line only 7 

 from origin to vent (Reinhardt counted 11 in his typical 

 specimen); the remainder cannot be distinguished among 

 the scales. In one -or two other species I have also found 

 traces of this supra-lateral line, .but less distinct, owing to 

 the greater extent of the scaled integument ; probably, how- 

 ever, it must be regarded as a continuation of the mucous 

 pores of the head, and not strictly as a lateral line. 



On the operculum, too. occurs a semicircular series 

 of pores, and a short series extends straight across the 

 point of the snout, close to the margin. 



Colour. — A uniform whity greyish-brown, without 

 spots or bands. An indistinct dusky stripe extends along 

 the mesial line, and another along the posterior portion of 

 the base of the dorsal. On the head, there is a dark patch, 

 near the extremity of the gill-plate. Pectorals whitish, as 

 also the anal and the under surface of the head; belly 

 bluish-black, margin .of vent white. The scales are ligliter 

 than the ground-colour. 



Distribution. — The only individual of this species 

 ever recorded, is the typical specimen sent to the Zoologi- 

 cal Museum at Copenhagen, from Omenak (Umanak), in 

 Greenland, 1837. Its total length is about 449""»; the 

 length of the head 123""". The new specimen from the 

 north coast of Spitzbergen — a young individual — was, as 

 mentioned above, taken in the temperate area (temperature 

 at bottom -|- 1.1° C.) on a clay bottom, in August 1878.

Diagnosis. — Exceedingly elongate. Colour a uniform 

 greyish-brown. The scales (they develop late and irregularly) 

 cover in the fully developed stage the whole of the body, 

 ivhereds the head, the nape, and the fins are naked. Teeth 

 comparatively strong; the series on the palatine bones exceed- 

 ingly short. The' height' oj_ the body is to the total length.
