E anden, hvor Undersidens Felt ai samme Farve støder. til. 

 P'renideles er Suudesi^idsen nirtrkt bruiisort. ligesom Hovedets 

 hele forreste Rand. Paa Undersiden have de mørkfarvede 

 Pai'tier og den hvide Bundfarve omtrent ligestor Udstræk- 

 niug. Disse farvede Fetter gaa hen imod Randen af Lege- 

 met (hos det i nogeu Tid paa Spiritus opbevarede Exem- 

 plar) over til næsten brunsort. Ingen af disse Felter 

 overskrider Bugeus Midtlinie. 



Deres Udstrækning hoa det forhaandeuværeude Indi- 

 vid kan kortelig beskrives paa følgende Maade. Et stort 

 sort Felt udbreder sig over den ydre Del af Pectoralen; 

 fra Pectoral vinkel en fortsa^tter dette sig langs hele den 

 forreste Profilrand (men blot umiddelbart i selve Randen), 

 lige hen til Snudespidsen. .Bagtil forener dette Felt sig 

 med et større Parti af samme Farve, der skyder sig op 

 paa Bugens Sider. Foran Mundspalten findes intet farvet 

 Parti (undtagen Randen af Snuden); men mellem (ijælle- 

 spalterne lindes en mindre Samling runde, tildels sammen- 

 tiydende Pletter. \'entralerne ' have. ligesom Pectoralerne, 

 brunsorte Rande : de accessoriske ( «enerationsorganer ere lige- 

 ledes paa Undersiden sorte, hvilken Farve udbreder sig til 

 en større Plet foran deres Rod. Hele Halens Underside 

 er énsfarvet sort. 



Sandsynligvis vil denne Farvefordeling vise sig noget 

 varierende hos ludividerne. 



Føde. ^'entrikelen var fuldproppet af Crustaceer og 

 Fiske. . Den væsentligste Del bestod af omkr. 50 kjæmpe- 

 raæssige Individer af TJiemisto l/hellida, tildels endnu ganske 

 hele; fremdeles Stykker af den i 1874 af Bucliholz i ,.2te 

 Deutsche ^"ordpolarfahrt-' beskrevne smuktfarvede Decapode 

 Hymenodora (/lacialisK 



Fiskene vare 3 i Autal. hvoraf idetmindste de 2 vare 

 Lycoder. Den største af dem havde en Totallængde af 

 185"™, og en Hovedlængdé af 41"""; den yderste Halespids 

 manglede, ligesom Huden og de fleste Finnestraaler. saa- 

 ledes. at Individet ikke lod sig med Sikkerhed bestemme; 

 men paa Grund af Taudbygningens Styrke, de lange og 

 brede Pectoraler, samt del; store Hoved, kan det maaske 

 henføres under L. Jufkeni. Den anden Unge af en 

 Lycodes var stærkere angreben af Fordøjelsen, og ganske 

 ubestemmelig; af et tredie Individ fandtes blot Rygraden 

 i Behold, og denne kan ligeledes have tilhørt en ung 

 Lycodes. 



Udbredelse. Hidtil er blot kjeudt det eneste, oven- 

 for beskrevne Individ, en Han, optaget omtrent under 80" 

 N. B. i Havet vestenfor Xord-Spitsbergen; dette er tillige 

 det ;iordligste Punkt paa' Jorden, hvor denne Slægt hidtil 

 har været bemærket.

to the similarly coloiu-ed patch on the under surface. Ex- 

 tremity of the snout, too. and the entire anterior margin 

 of the head dark-brown, approaching to black. On the 

 under surface, the space occupied by the dark portions of 

 the skin and the white of the ground is a-bout equal in 

 extent. The dark symmetrical patches deepen in colour 

 as they approach the margin of the disk, almost to a 

 In'ownish black; none of them cross the central alxlominal line. 



Their distribution in the example obtained may be 

 briefly described as follows. A large black patch occurs on 

 the lateral margin of the pectorals,; from the angle of the 

 pectorals it extends along the anterior line of the margin 

 of the body (at the extreme edge however only) to the tip 

 of tlie snout. Behind, this patcli unites with another, 

 similarly coloured, running up the sides of the belly. 

 Anterior to the cleft of the mouth the skin is uniformly 

 ■white, save the margin ol' the snput-, between the branchial 

 apertures occiu- a small cluster of round spots, some of 

 which are confluent. Edges of ventrals brownish black 

 like those of jiectorals; the accessory sexual appendages 

 on the under surface black, this colour expanding to a 

 large spot opposite their base. Under surface of tail 

 entirely black. 



This distribution of colour will probably be found to 

 vary in different individuals. 



Food. — The stomach was full of crustaceans and 

 divers tishes. The principal part of the contents consisted 

 of about 50 enormous examples of the Hyperoid Themisto 

 Ubellula, several of them quite entire; and of fragments 

 of the Decapod Hipiienodora glacialis\ described in 1874, 

 by Buchholz. in -'Zweite Deutsche Nordpolarfalirt." 



The hshes were 3 in number, of which two at least 

 were Lycodes. Total length of the largest 185"""*; length of 

 head 4I*™; the tip of the tail, the whole of the skin, and 

 most . of the fin-rays were gone ; hence this jndividual could 

 not with certainty be determined; but the structure of the 

 teeth however, the great length and breadth of the pectoral 

 fins, and the size of the head gave reason to regard it as 

 an example of L. lutkeni, afterwards described. Another 

 young Lycodes was wholly indeterminable, being in stiU a more 

 advanced stage of the digestive process; of the third, the 

 vertebral column only remained — not improbably, too, 

 that of a young Lycodes. 



Distribution. — Tke only example lutherto met with 

 is the male specimen now described, taken in lat., about SO <• 

 N., at sea, west of the northern coast of Spitzbergen, the most 

 northerly locality, too, in which this genus is yet known 

 to occur.
