Dorsalen begyuder over Pectoraleriies Rod: deus 

 8traaler. der ere (il eller 62. sjeldnere GO eller 63 i Au- 

 tal. ere i Begyndelsen korte, og 1 eller et Par af dem ere 

 ved Reelen næsten fri : den har- omtrent fra Midten af en 

 jevn Hojde bagover, og den sidste Straale er ved en Mem- 

 bran forbunden raed'Caudaleu. 



Analen har 41 — -12 Straaler (sjeldnere' 40 eller 43); 

 den forste. der er ganske kort. er en Pigstraale. de øvrige 

 leddede, og i Spidsen kløvede. Den er fortil lav. men til- 

 tager i Hojde bagtil. saaledes at dens sidste Straale er ^/s 

 hengere, end den tilsvarende i Dorsalen. Denne sidste Anal- 

 straalé er (ligesom Dorsalens) efter sin hele La^ngde ved 

 en Membran forenet med Caudalen, og lægger sig læugere 

 ud over dennes Rod. end det er Tilfældet med den tilsva- 

 rende Straale i Dorsalen. 



Caudalen er jevnt ægformigt afrundet. hos de yngre 

 noget stumpere; som ovenfor nævnt er den ved Grunden 

 forbundet ved en Membran med Dorsalens og Analens 

 sidste Straale. Den hestaar af omkring 17 længere Straa- 

 ler. der alle ere leddede (og med Undtagelse af et ^ar 

 paa hver af Siderne, tillige delte), foruden a f et Par korte 

 og uleddede Stottestraaler. 



Pectoralerne ere jevnt afrun'dede. noget kortere, end 

 Hovedet, eller omtrent af Caudalens Læugde. samt relativt 

 noget længere hos de yngre, end hos de ældre Individer ; 

 de indeholdes i Totallængdeu omtrent 8 Gange. Straaler- 

 nes Antal er typisk 14. sjeldnere 13 eller 15; alle ere 

 leddede. o*g de øverste og mellemste tillige kløvede. Hos 

 de nederste Straaler rager Spidsen et kort Stykke udenlor 

 Membranen. 



Ventralerne ere forholdsvis smaa, indeholdes hos det 

 største af de erholdte Individer (Totall. 122"""') 24V Gange 

 i Totallængden, hos de mindre omtr. 22 Gauge i denne. 

 De beståa af en særdeles kort Pigstraale. og 3 leddede 

 Straaler, alle yderst spinkle. 



Sidelinien. Som hos alle Arter er Sidelinien utyde- 

 lig, men kan dog overalt forfølges i sin Helhed. Den ud- 

 spriuger ved Gjællespaltens øvre Ende, og gaar derfra ret 

 ud mod Caudalen i den Fure. som danner Legemets Midt- 

 hnie. Porerne ere overalt ganske smaa og tætstaaende. 

 saaledes, at der i det Hele kommer omtrent 2 Porer for 

 hver Hvirvel. 



SkjæUene. Disse .ere smaa og lidet fremtrædende ; de 

 ere særdeles fastsiddendé, og ordnede i tætstillede Rækker. 

 De strække sig frem paa Hovedet, hvor de bedække Kiu- 

 derne. men ere her cycloide. medens . de paa Legemet ere 

 imbricate. 



Farven er afvigende fra. de øvrige Arters df>rved. at 

 Pletterne ere faa og utydelige. Bundfavven er graagul; 

 Krøyer og Reinhardt beski'ive sine Lulivider som ganske 

 ensfarvade; Malmgren paaviser derimod. at Pletter ere 

 tilstede hos det friske Individ, men forsvinde efterhaanden 

 mere, naar' dette en Tid har været opbevaret paa Spiritus. 

 Hos de fleste af de under Nordhavs-Expeditionen erholdte 

 Individer ere endnu disse Pletter delvis i Behold, skjont 

 de elte ere svage eg næsten' usynlige. Hqs det største af 



Dorsal commencing immediately above the origin of the 

 pectorals ; number of rays 6 1 or 62, more rarely 60 or 63, 

 Jthe first in the series short. 1 . or sometimes 2. almost free 

 at the base ; from about the middle of the fin. the depth con- 

 tinues uniform, the terminal ray being connected with the 

 base of the caudal by a thin membrane. 



Anal furnished with 41 — 42 rays (more rarely 40 or 

 43), the tii'st, which is spinous, being quite short, the rest 

 articulated and branched at the points. In the anterior 

 jjart depressed, this fin gradually increases in depth, its 

 terminal ray being one-fifth longer than that perrespending 

 with it in the dorsal. The last of the anal rays (in com- 

 mon with that of the dorsal )_ attached throughout its entire 

 length by a connective membrane to the base of the cau- 

 dal, and extending farther beyond it than does the terminal 

 ray in the dorsal. 



Caudal rounded (subtruncate). in younger individuals 

 somewhat more obtuse : at the base connected by a mem- 

 brane with the terminal rays in the dorsal and anal. This 

 fin consists of about 17 long rays, all of them articulated, 

 and, saving one or two • on either side, bipartite also, 

 exclusive of a couple of sliort rudimentary rays without 

 articulation. 



Pectorals uniform convex, in length somewhat shorter 

 than than the head, or about equal to the caudal, and 

 relatively a trifle longer in young than in adult individuals; 

 their length is to total length nearly as 1 to. 8.. Typical 

 number of rays 14. — 13 or 15 more rarely observed; they 

 are all articulated, the uppermost and the medial likew^ise 

 cleft. In the lowermost rays, the points slightly projecting 

 above the membrane. 



Ventrals comparatively small: length in the largest 

 of the specimens obtained (total length 122""") is to total 

 length as 1 to 24, in the smaller examples, about as 1 to 

 22. They consist of one exceedingly short spinous i-ay, 

 and 3 articulated ra3'S, all extremely slender. 



Lateral Lute. — As in all the other species, the 

 lateral line is indistinct, but can be traced throughout 

 its entire length. It commences at the upper extremity 

 of the branchial opening, passing from thence straight to 

 the caudal, along the furrow forming the mesial line. The 

 pores are exceedingly minute and close, about 2 to each 

 vertebra. ■ 



Scales. — Small, and not plainly visible, firmly 

 attached to the skin, and closely arranged in regular series. 

 They extend out on the head, where they cover the cheeks; 

 here, however, they are cycloid, but imbricate on the body. 



Colour. — In its marking, this species is distinguished 

 by the spots, wliich are few and . indistinct. Ground-coloiii- 

 gi-eyish -yellow. Kroyer and Reinhardt both describe their 

 specimens as of a uniform colour; Malmgren, however, has 

 shown that spots undoubledly occur in individuals newly 

 taken, but gradually become obsolete in spirit-specimens. 

 In most of the examples obtained on the Expedition 

 these spots are still obvious, though less distinct. The 

 larsest individual is marked with a number of light brown- '
