Individer er tildels dobbelt. Straalernes Antal ligger melleiii 

 49 og 52 ; naar Mohr for sit Typ-Exeiuplar opgiver 54. tør 

 dette ansees som en iudividuel AtVigelse, hvis det ikke be- 

 ror paa en fejlagtig Undersøgelse. 



Caudalen udmærker sig fremfor de ovrige Arters ved 

 sin tilspidsede Form, der især hos. de ældre Individer er 

 stærkt udpræget. Den er fuldkommen adskilt fra Dorsa- 

 lens og Analens sidste Sti-aaler. endskjønt disse lægge sig 

 ud over Haleroden. Hos yngre Individer er Finnen noget 

 mindre tilspidset. Straalernes Antal er omtr. 15, hvortil 

 kommer et Antal korte og uleddede Støttestraaler paa hver 

 Side; de 11 — 12 mellemste er tydeligt articuleredé, samt 

 klovede. 



Pectoralerne tælle 15. sjeldnere 14 Straaler, ere jevnt 

 afruudede. forholdsvis korte, samt indeholdes hos de yngre 

 Individer 8 — 10, hos ældre lige til 13 Gange og derover i 

 Totallængden. Med Undtagelse af den øverste, ere de alle 

 kløvede. 



Ventralerne ere af middels Længde. have 1 særdeles 

 kort, uleddet Straale, og 3 længere leddede, tilsammeu 4 

 Straaler. Hos yngre Individer indeholdes den enduu 17 

 Gauge i Totallængden, men hos ældre lige til 29 Gange 

 (og derover). 



Sidelinien er særdeles utydelig, udspriuger over Gjælle- 

 spalteu, og følger efter sit hele Lob Legemets Midtfure. 

 Porerue ere yderst smaa og tætsiddeude. 



Farven er blegt gulbrun med et stort Antal dels 

 større, dels mindre graabrune Pletter nedad Legemets Sider ■ 

 alene Bugen er uden Pletter, og noget mere sølvfarvet. . 

 Størrelsen og Antallet af disse Pletter varierer betydeligt; 

 hos de fleste middelsstore Exemplarer sees oiiitrent <S større 

 saadanne af strække sig henad Siderne under Midtlinien, 

 og undertiden tillige en lignende Række over denne, hvis 

 Pletter, der tildels • gaa ud over Granden af Dorsalerne, 

 alternere -med den nedre Rækkes. Mellem disse staa altid 

 mindre Pletter og Skygninger, der ofte ere stærkt sam- 

 menløbende. 



Dorsalen har sja-aatlobende Tverbaand. Caudalen lige- 

 ledes 3 — 4 (hos ældre Individer flere) Tverbannd. medens 

 de øvrige Finner synes uden Tegninger. Hovedet er mere 

 marmoreret. og har en messingfarvet Iris. hvis øvre Band 

 er sort. 



Udbredelse. L. Jampdraeformis er for Tiden kjendt 

 fra (irøuland, Island, Spitsbergen, samt fra Europas Nord- 

 vestkyst ned til Kattegat. Medeus der endnu foreligge 

 blot faa Individer fi-a Grønland og Island, er den flere 

 Gange erholdt ved Spitsbergen .allerede under de svenske 

 Expeditiouer, og den gaar her op til idetmindste 80o N. B. 

 Derimod synes den ikke at være sjelden paa de fleste 

 Punkter langs den norske Kyst fra Finmarken af og ned 

 til Christianiafiorden. og jeg har ojitaget indtil et Dusin 

 Individer i et enkelt Kast med Torskegarn i Porsanger- 

 fjorden i Vest-Finmarken. Dens Sydgrændse synes at være 

 Bohuslen, hvor et Par Individer ere erholdte saa lauiit 



of • the lish, sometimes becomes double in mature individuals, 

 Number of rays varying between 49 and 52; it is true. 

 Mohi' gives 54 for his typical specimen, but this, if cor- 

 rectly observed, must be a mere individual deviation. 



Caudal, more especially in adults, characterised by 

 its acuminate form; it is separated from the terminal 

 rays in the dorsal and anal, which extend notwithstanding 

 beyond the base of the tail. Individuals comparatively 

 young have this fin somewhat less acuminate. Number of 

 rays about 15, exclusive of numerous short auxiliary rays 

 on either side, without articulation; 11 or 12 of the middle 

 ones distinctly articulated, and branched. 



Pectorals furnished with 15, more rarely with 14 

 rays; uniform convex, comparatively short, their length, in 

 young individuals, being as 1 to 8 — 10, in mature indivi- 

 duals as 1 to 13, and above. Pectoral rays all branched, 

 with the exception of the uppermost. 



Veutrals of moderate length; have 1 short ray.' not 

 articulated, and 3 longer articulated rays, or, altogether, 4. 

 Length of iin. in young individuals, is to total length as 1 

 to 17. luit in adults the proportion becomes as 1 to 29 

 (and even above). 



Lateral Line. — Very indistinct; commences' immedi- 

 ately above the branchial opening, passing from tlience 

 straight down the medial furrow of the body. The pores 

 closely set. and extremely minute. 



Colour. — C!olour pale }-ellowish-browu, relieved with 

 a number of greyish-brown spots, extending laterally along 

 the body ; the abdomen alone spotless, and of a somewhat 

 more silvery appearance. These spots vary considerably in 

 magnitude and number ; most middle-sized examples are 

 marked with a row of eight, stretching along the sides 

 below the mesial line, and occasionally, too, with a similar 

 series above, the sjjots composing it, which sometimes ex- 

 tend beyond the base of the dorsals, alternating with those 

 in the lower row. The interspace always exhibiting spots 

 and cloudings, the former frequently confluent. 



Dorsal marked with oblique transverse bands; the 

 caudal likewise has 3 or 4 transverse bands (in adults a 

 gi'eater number), whereas the other fins would appear to 

 be without markings of any kind. Head to a greater ex- 

 tent mottled ; irides of a brassy yellow, black above. 



Distribution. — Up to the present time. L- hmijie- 

 trceforntis is known to occur on the coast of Greenland. 

 Iceland, Spitzbergen, and the shores of north-western Eu- 

 rope, as far south as the Cattegat. But few examples of 

 the species have been hitherto obtained from Greenland .and 

 Iceland; off Spitzbergen, however, it has been repeatedly 

 observed, individuals having been taken on each of the 

 Swedish Expeditions to the Polar Sea, and its range ex- 

 tends at least as far north as 80". Along the coast of 

 Norway, from Finmark to the Christiania Fjord, it would 

 appear to be rather a common fish in most localities; I 

 once took as a many as a dozen individuals at a single
