vedet, ore følgende de mest iøjnefaldende. En Række ad 

 omtrent i» Porer strækker sig fra Snudespidfen langs Ran- 

 den af Overkjæven indtil bagenfor Mundvinkelen. Kivi den 

 sidste af.disse Porer stiger vertical! nedad en Række finere 

 Porer, oftest 4 i Antal, indtil den nedre Rand ai Prae- 

 operculum; herfra fortsætter sit; en Række ai omtreni 6 

 grovere Porer langs Handen ai Praeoperculum bagover og 

 opover, indtil den standser omtrent i Eøjde med Grjælle- 

 spaltens øvre Ende. Endelig strække sig Langs Ohderkjæven, 

 2 næsten parallelle Rækker, den indre med 5 mindre, den 

 ydre med 3 grovere Porer. Mellom Ojneno danne 3 (like- 

 ledes grovere) Porer en forti! aaben Vinkel. Paa Siderne 

 af fanden strækker sig fraØjet lien til Gjællespaltens ovre 

 Ende en Række af 4 Porer, lovrigt tindes spredte Porer 

 paa ! 'anden, ligesom ogsaa Antallet i de normale Rækker 

 viste sig at være noget varierende Ims de 2 undersøgte 

 Individer. 



Skjælbeklædning. "Skjællene ere udbredte over hele 

 Legemet. Paa Hovedet strækker Skjælbeklædningen sig 

 frem indtil inellem de bagre Na-sebor. hvorimod selve Snu- 

 den er nøgen; paa Hovedets Underside er Skjælbeklædnin- 

 gen ligeledes udbredt overalt paa den ubedækkede Del af 

 Grjællehinden indtil selve Spidsen af Dnderkjæven, der er 

 riøgen. Paa Dorsalen og Analen strække Skjællene sig ud 

 næsten lige til Spidsen af Straaleme; paa Pectoralerne 

 tindes de blot ved Roden. 



Farve. Farven var i levende Live rødgraa, paa Ho- 

 vedet og Bugen gaaende over i blaagraat; paa Hovedets 

 Underside strækker denne Farve sig frem overalt paa Gjælle- 

 hindens ubedækkede Dele. Spidsen af Dorsalen. Analen, 

 og Ca uda len vare smukt røde; samme Farve kavde de 3 

 Skjægtraade, samt den første forlængede Straale i Iste 

 Dorsal. Pectoraler og Ventraler vaie bos det ene Exein- 

 plar i Spidsen rode. hos det andet I ila a lige med lysere Spid- 

 ser. Muudbulen var bvid. Etterat Individerne have været 

 opbevarede paa Spiritus, er Farven bleven mere ensfarvet 

 rødgraa overalt: Hovedets Skjægtraade, samt Iste Dorsal- 

 straale have tabt sin rode Farve, bvilket ogsaa er Tilfældet 

 med Ventralerne og tildels med Pectoralerne. De sidste have 

 derimod faaet lysere Pletter paa den rødlige eller blaalige 

 Bund. 



Føde. I Yentrikelen af det ene Individ fandt jeg 

 Skelettet af en liden Fisk. hvisLængde var omtrent 1 00"""; 

 en sølvglindsende Svømmeblære var dog endnu tilstede, men 

 Arten lod sig ikke bestemme, da Hovedet var næsten for- 

 tæret. Desuden fandtes diverse Stykker af Deca poder, som 

 det syntes, af Hip.polyter. 



Det andet Individ havde Yentrikelen fyldt af The- 

 misto I/hrlhtla, en Amphipode a f Hyperiderues Familie, der 

 saaledes trænger ned til eu anselig Dybde, skjønt den maa 

 ansees for at have sit Hovedtilhold i de højere Vandlag; 

 fremdeles en Anonyx, sandsynligvis A. \agma. 



Udbredelse. Formlen Nordhavs-Expeditionens 2 In- 

 divider fra Havet mellem Spitsbergen og Beeren Eiland ere.

the surface of the bead, the following are the mosl con- 

 spicuous: — A row. composed ol' about '.I pores, extending 

 Ironi the point of the snout along the margin of the upper 

 jaw a little behind tin angle of the mouth. Branching 



vertically downwards from the last ol' these pores, a scries 

 of about 4 smaller pores is seen extending to the lower 

 margin of the preoperculum ; from this point a scries of 

 about (i large pores runs along the margin of the preoper- 

 culum, backwards and upwards, terminating in a line with 

 the upper extremity of the gill-opening. On the lower jaw 

 occur two rows almost parallel, the inner composed of 5 

 small, the outer of 3 large, pores. Between the eyes are 

 3 pores (these, too, comparatively large), marking off an 

 angular space, open anteriorly. On either side of the fore- 

 head, from the eye to the upper extremity of the branchial 

 opening, extends a row of 4 pores. Moreover, isolated 

 pores occur on the forehead: and the number in the nor- 

 mal series varies somewhat in the 2 individuals examined. 

 Scales. -^- The scales cover the entire surface of the 

 body. On the head, they extend forwards between the 

 posterior nostrils, leaving the snout naked; on the under 

 surface of the head, they likewise envelop the whole of the 

 uncovered portion of the branchial membrane, saving the 

 extreme point of the lower jaw, v. kick is naked. On the dorsal 

 and anal, the scales extend almost to the points of the rays; 

 on the pectorals, they occur only on the base. 



Colour. — Colour in live examples reddish -grey, 

 changing to bluish -grey on the head and abdomen; the 

 latter shade extends, too, over the whole of the uncovered 

 portion of the branchial membrane. Tips of dorsal, anal, 

 and caudal of a fine red ; this colour likewise distinguishing 

 the- barbels and the first elongated ray in first dorsal. Tips 

 of pectorals and ventrals in one example red ; in the other, 

 the tips were bluish. Cavity of the mouth white. The 

 specimens having been preserved some time in spirits, the 

 colour has changed to a more uniform reddish-grey : the 

 barbels and the first dorsal ray have lost their brilliant 

 red colour; this is the case too with the ventrals, and, to 

 some extent, with the pectorals; in the latter, the reddish 

 or bluish ground has become flecked with lighter spots. 



Food. — In the ventricle of one of the individuals 

 was the skeleton of a small fish, length about LOO"""; the 

 swimming-bladder, of a silvery lustre, was still present, but 

 the head being very nearly digested, there was no means 

 of determining the species; the stomach also contained 

 divers fragments of Decapods, apparently of the genus 

 H'ppoh/fe. 



The other individual had the ventricle distended with 

 Themisto libellula, of the family Hyperidas, a species de- 

 scending therefore to a considerable depth, though its true 

 habitat has been held to be exclusively the upper strata of 

 the ocean; an. Anonyx, probably A. lac/eiia, was also found. 



Distribution. — Exclusive of the two individuals taken 

 on the North Atlantic Expedition between Spitzbérgen and
