vedet, ere følgende' de mest iøjuefaldende. En Rækte af 

 omtrent 9 forer strækker sig fra Snudespidsen laugs Ran- 

 den af Overkjaneii indtil bagenfor Mundvinkelen. Fra den 

 sidste af disse -Porer stiger verticalt nedad en Eække liuere 

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

 operculuni : herfra fortsa^tter sig en Række af omtrept 6 

 grovere Porer laugs Randen af Praeoperculum bagover og 

 opover, indtil den standser omtrent i Højde med Gjælle- 

 spalteus øvre Ende. Endelig sti"ække sig langs Underkjæven 

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

 ydre med 3 grovere Porer. Mellem Øjneue danne 3 (lige- 

 ledes grovere) Porer en fortil aaben Vinkel. Paa Siderue 

 af Isanden strækker sig fra Øjet hen til CTJællespaltens' øvre 

 Ende en Rrekke af 4 Porer. løvrigt tindes spredte Porer 

 jiaa J anden, ligesom ogsaa • Antallet i .de normale Rækker 

 viste sig at være uoget varierende hos de 2 undersogte 

 Individer. 



SkjælbeJilædning. Skjællene ere udbredte over hele 

 Legemet. Paa ■ Hovedet . strækker SkjadbékLædningeu sig 

 irem iudtil mellem de bagre Kæsebor. hvorimod selve 8uii- 

 den er nøgen; iiaa Hovedets Underside er Skjælbeklædniu- 

 gen ligeledes udbredt overalt paa den ubedækkede Del af 

 Gjællehinden indtil selve Spidsen af Underkjæven, der er 

 nøg«n. ■ Paa Dorsalen og Analeu strække Skjællene sig nd 

 næsten lige til Spidsen af Straalerne; paa Pectoralerné 

 fiudes de blot ved Roden. 



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

 vedet og Bugen .gaaeude over i blaagraat;. paa Hovedets 

 Underside stra^kker denne Farve sig frem overalt paa (-rjælle- 

 hiudens ubedækkede Dele. Spidsen af Dorsalen. Analen, 

 og Caudalen vare smukt røde ; s-amme Farve havde de 3 

 Skjægtraade, samt den . første forlængede Straale i Iste 

 Dorsal. Pectornler og Ventraler vaie hos det ene Exem- 

 plar i Spidsen røde, hos det andet blaalige med lysere Spid- 

 ser. Mundhulen var hvid. Efterat Individerne have været 

 ojibevarede jjaa Sjjiritus, er Farven Ideveu mere ensfarvet 

 rødgraa overalt; Hovedets Skjægtraade, samt Iste Dorsal-- 

 straalé have tabt sin røde Farve, • hvilket ogsaa er Tilfældet 

 med'Ventralerne og tildels med Pectoralerné. De sidste have 

 derimod faaet lysere Pletter paa den rødlige ellrr blaalige 

 Buud. ' . • • ■ 



Føde. I Veutrikelen af det ene. Individ fandt jeg 

 Skelettet af en liden Fisk. hvis Læ^ngde var omtrent i UO'™; 

 en sølvglindsende Svømmeblære var dog euduu tilstede, men 

 Ai"ten lod sig ikke bestemme, da Hovedet var næsten for- 

 tæret. Desiulen fandtes diverse Stykker afDecapoder, som 

 det syntes, af Hippolyter. 



Det andet Individ havde Veutrikelen fyldt af The- 

 mist.o lihelhda, en 'Amphipode' af Hyperidernes Familie, der • 

 saaledes trænger ned til en anselig Dybde, skjønt den maa 

 ansees for at have sit Hovedtilhold i de bøjere Vandlag; 

 fremdeles en Anonyx. saudsynligvis A. lagena. ■

11 the surface of the head. the following' are the most con- 

 spicuous: — A tow. composed of about 9 pores, extending 

 from the point of the 'snout -along the margin of the upper 

 jaw a little behind the angle of . the mouth. Branching 

 vertically downwards from the last of these pores, a series 

 of about 4 smaller ,, pores is seen extending to the lower 

 margin of the preoperculum : from this point a series of 

 about 6 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 i^ndividuals examined. 

 Scales. — The scales cover the entire surface of the 

 body. On the head, they extend forwards betw-een the 

 posterior nostrils, leaving the snout nak^-d; 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. hich is n-.vked. On the dorsal 

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

 on the iiectorals, they occur only on the base. 



Colour. — •" Colour in- live examples reddish - grey. 



■changing to bluish -gi-ey- on the head and abdomen; the 

 latter shade extends, too, over the' wliole of the uncovered 

 j)ortion of tlui' briaichial membrane. Tips of dorsal, anal, 

 and caudal of a fine red; this colour likewise distinguishing 

 ■the barbels and the first elongated i-ay in first dorsal. Tips 

 of pectorals and ventlals 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 lias changed to a more uniform reddish-grey; the 

 barbels and tlie first dorsal ray have lost their brilliant 

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



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

 or bluish ground has become flecked with lighter spots. 



Pood. — In the ventricle of one of the individuals 

 was the skeleton of a small fish, length about 100'"'"; the 

 swimming-bladdei', of a silvery lustre, was still present, but ' 

 the head being very nearly digested, there was no means 

 • of determining the sjjecies; the stoina'ch fllso contained 

 divers fragments of Decapods. ai)parently of the genus 

 Hipijolyte. 



The' other individual had the ventricle distended with 

 Themisto libeJlufa, of the family Hi/peridce, a species de- 

 scending therefore to a considerable depth, though its true 

 habitat has been held to be exclusiyely' the upper strata of 

 the ocean: an Anmii/.r, probably A. Jagena. was also found. 



Distribution. — Exclusive of the two individuals taken 

 on" the North Atlantic Expedition between Spitzbergen and
