Finnestraalerne ere særdeles bløde og spinkle, temme- 

 lig fast nedtrykte mod Legemet, og kunne neppe nogen- 

 sinde rejses til sin fulde Højde. De ere tillige saaledes 

 iudhj'Uede i den bløde og slimede Hud. der bedækker Le- 

 gemet, at de ikke, uden at Exemplaret delvis odelægges, 

 kunne tælles, og selv da kun med Yauskeligbed. tStraale- 

 antallet hos Individ a syntes at være følgende : D. 55 ; 

 A. 45; P. 33; C. 14. Hos Individ r var der mindst 52 

 Straaler i Dorsalen. 



Analen og Dorsalen bedække bagtil omtrent det halve 

 af den temmelig korte og spinke Caudal, og uden at Ana- 

 len rager hengere tilbage, end Dorsalen. 



Pectoralerue have sit Udspriug lige ioran paa Stru- 

 ben. umiddelbart mellem Underkjævernes -Symphyse, og 

 støde her ganske tæt sammen, uden dog, som det synes, 

 at være helt sammen voxne fortil. De forreste 8 — 10 Straa- 

 ler ere lidt forlængede, og rage som korte snoede Traade 

 ud over Membranen; herved dannes maaske et mere ud- 

 viklet 1'øleorgan. end hos de øvrige Liparider. Finnens 

 meUemste og største Del har lave Straaler. den ovre Del 

 atter forlængede. Den hele Finne danner en halvcirkel- 

 formig Bue langs Hovedets LTnderside, og følger næsten 

 nojagtigt den Linie. som den nedre Raud af Operculum og 

 Suboperculum danne. 



Farven er blegt rødgi-aa eller hvidagtig, uden Tegnin- 

 ger eller Baand; under Foi'storrelse viser den sig at være 

 dannet af yderst smaa. sorte Punkter, der dog staa saa 

 jevnt fordelte, at de blot tildels give Rygsiden en ubetyde- 

 ligt mørkere Skygning, men ikke danne Pletter. Iris var 

 i levende Live violet. 



Hele Legemet er iovTigt indhyllet i en løs, klæbrig. 

 næsten gelatinøs Hud, ligesom hele Legemet er af en løs 

 og halvt transparent Consistents. skjønt alle Individer bleve 

 satte levende jjaa stærk Alcohol. 



Føde. I Yentrikeleu af det mindste Exemplar (fra Jan 

 Mayen) fandtes blot et Stykke af en Kalksvamp; saudsyn- 

 ligvis. har der paa det aftidte Stykke siddet et eller andet 

 lidet Dvr.

Fin-rays exceedingly soft and slender, rather firmly 

 pressed against the body, and rarely if ever admitting of 

 being raised to their full height. Moreover, wholly envel- 

 oped as they are in the soft and viscid membrane covering 

 the body, they cannot be counted, except by mutilating the 

 specimen, nor even tlien without difficulty. The number 

 of tin-rays in example a was apparently as follows: — 

 D. 55; A. .45; P. 33; C. 14. In examjile r, the dorsal 

 was furnished with at least 52 rays. 



The anterior half of the somewhat short and slender 

 caudal is almost covered by the anal and dorsal. — and with- 

 out the anal extending farther back tlian the latter tin. 



The pectorals commence far forwards on the throat, 

 immediately between the symphysis of the lower jaw. apjiroxi- 

 mating. but without, it seems, being strictly contiguous at their 

 origin. The foa-emost 8 or lU rays slightly elongated, projecting 

 beyond the membrane, as short, spiral-shaped filaments; by 

 this peculiarity of structure the species, perhaps, is furnished 

 with a more delicate organ of touch than are any of the other 

 Liparides. The intermediate and largest jjortiou of tlie tin 

 has short rays, the upper is elongated. The entire fin, 

 semi-circular in form, extends along the under surface of 

 the head, and almost exactly in a line with the lower 

 margin of the operculum and suboperculum. 



Colour pale reddish-grey or whitish, no bands or mark- 

 ings of any kind; a microscopic examination shows it to 

 be produced by a multitude of exceedingly minute black 

 maculæ. in distribution, however, so uniform as merely to 

 give the upper surface a slightly darker shade ; spots there 

 ai'e none. Irides, in the living specimen, violet. 



For the rest, the whole body is enveloped in a lax. 

 viscid, almost glutinous membrane, the body itself being semi- 

 transparent, and of a jelly-like consistency, notwithstanding 

 the specimens were all of them, while yet living, immersed 

 in ijroof-spirits. 



Food. — The ventricle of the smallest example (from 

 Jan Mayen ) contained only a small portion of a calcareous 

 sponge ; probably there had been some small animal on the 

 fragment bitten off. 



Distribution. — Assuming, therefore, the individuals 

 taken on the North Atl. Expedition to be identical with 

 the two typical specimens from Greenland, described under 

 the name Careprodiis reinhardi, this species — disregarding 

 all doubtful synonyms — is known to inhabit the Arctic waters
