Føde. Hos de Individer, der aabnedes for ;it under- 

 søge Ventrikelens ludliold, fandtes dette at udgjøre i Re- 

 gelen niiudre Dyr. især Criistaceer. 



Individet 1, optaget fra 1110 Favnes I)yb, iudelioldt 

 af bestembare Dele et Par Ampliipoder. hvoriblandt en 

 Fhojtis crénidatus, (Boeck), samt en Diiliéiia, sp. : frem- 

 deles et Exemplar af den blodrøde Decapode Hymenodora 

 gladalis (Bucbb.), et stort Individ af en Isopodc. der tid- 

 ligere var opført som Idothea sahini, Kr., men som af Prof. 

 G. 0. Sårs i 1880 er beskreven som en ny Art under 

 Navn af Chiridofhea megcdura. Endelig fandtes en 'Del 

 Ccdanns finmmrhiais, (Gunn.). 



Individet m. optaget fra 1333 Favne, bavde i Ven- 

 trikelen et usædvanligt stort Individ af Themisto liheJhila, 

 (Mandt). et Exemplar af Eurycope cornuta. G. O. Sårs, 

 samt Dele af en Spongie. 



Individet o, optaget sammen med foregaaende fra 

 1333 Favne, indeboldt et Exemplar af Hymenodora glacia- 

 lis, (Bucbb.), et Exemplar af den samme nye CJiiridofhea 

 megcdura, G. 0. Sårs. samt af Amjjliipoder Themisto, libél- 

 hda, (Mandt), samt en Stegocejihahis. sp. Endelig fandtes 

 Dele af Kappen af en Cepbalopode. der maaske tilbørte 

 den under Expeditionen fra et lignende Dyb optagne Art 

 af Slægten Cirroiheidhis. 



Individet g, optaget fra 260 Favnes Dyb. indeboldt af 

 Ampbipoder flere Exemplarer af Tliemisto libelhda, (Mandt). 

 samt et Exemplar af en Anonyx; af Isopoder Eurycope 

 cm-nuta. G. O. Sårs; af Copepoder Calamus finmarchiaw, 

 (Gimii.) i adskillige Exemplarer. samt et Individ af en 

 endnu ' ubestemt Slægt af Calanider. der ai' Prof. Sårs 

 ansees for at staa nær Slægten Æ'Mc7/aeto ; endelig nf Cuma- 

 ceer en Diastyl/s stygia, G. 0. Sårs. 



Endelig fandtes i det største Individ {j}), optageu fra 

 1110 Favnes Dyb, en stor Pasiphae tarda, Kr. 



Det fremgartr af disse Lycodei-s Næi-ingsmidler. at de 

 fleste af de velbekj endte, ægte pelagiske Sodyr. der til visse 

 Tider i enorme Masser ere udbredte i de allerøverste Vand- 

 lag, ogsaa formåa at træuge ned til de allerstorste Dybder, 

 hvor vi bidtil bave kunnet granske Isbavets Dyreliv; og at 

 Lycoderne maa opfattes som udprægede Bundfiske, og derfor 

 blot kunne bente sine Næringsmidler ved eller paa Bun- 

 den, fremgaar bl. a. af den Omstændigbed, at der blandt 

 Næringsmidlerne bos L. frigidus indgaa Former, som den 

 ovennævnte Chiridothea, der neppe er istand til at hæve 

 sig Synderligt op fra Bunden. 



Opbcvarede levende i et Kar ombord, udviste Indivi- 

 derne ringe Livligbed. men holdt sig gjerne stille i halvt 

 sammenrullet Tilstand, omtrent saaledes. som man kau se 

 hos Zoarces viviparus ; Svømningen skeede med stærke 

 Svingninger af Legemet. Da de lagdefe paa Spiritus, vare 

 de dog yderst voldsomme.' og viste sig. som de fleste Bund- 

 fiske, temmelig seiglivede. 



Udbredelse. Under den Forudsætning. at de oftere 

 nævnte 2 spæde Yngel-In divider, der optoges paa Havbro- 

 ens ydre Skraaning udenfor Lofoten og Helgeland i Norge, 

 ere identiske med L. frigidus, foreligger Arten Ira den is- 



Food. — In the individuals opened with the object of 

 examining the contents of the ventricles, the food was found 

 to consist chiefly of small" animals, in particular crustaceans. 



Specimen /, taken at a depth of 1110 fathoms, had 

 in its stomach determinable parts of Amphipods, amongst 

 which were a Pliojcus crenulatus, (Boeck), and a Dulichia, 

 sp. ; also an example of the crimson Decapod. Hymenodora 

 glackdis, (Buchh.). a large Isopod. formerly mentioned as 

 Idothea sahini, Kr.. jjut which Prof. G. 0. Sars, in 1880, 

 described as a new species under the name of Oiiridothea 

 megaJura: finally, divers examples of Calanus Jimnarchicus. 

 (Gunn.). 



Specimen m, taken at a depth of 1333 fathoms, bad 

 in its ventricle' an exceptionally large individual of Themisto 

 liMluJa, (Mandt). an example of Eurycope cornida, G. 0. 

 Sars, and parts of a sponge. 



Specimen o, taken with the foregoing example at a 

 depth of 1333 fathoms, had in its stomach an example 

 oi Hymenodora glackdis, {Unchh.), an individual of the new 

 species Chiridothea megahtra (G. 0. Sars), and of Amphipods, 

 Themisto lihellula. (Mandt). and a Stegocephalus. sp. : finally, 

 parts of a CVphalopod. possibly belonging to the species of 

 the genus Cirrotheidhis obtained on the Expedition from a 

 similar depth. 



Specimen g. taken at a depth of 260 fathoms, had 

 in its stomach — of Amphipods : divers examples of Themisto 

 lihellula, (Mandt). and an Anonyx: of Isopods: Eurycope 

 cornuta, G. 0. Sars; of Copepods: Calanus finmarchicus, 

 (Gunn.) divers examples, and an individual of a genus of 

 Calanids, not yet determined, which Prof. Sars believes to 

 be a near congener of the genus EuiJtæta; finally, of Cuma- 

 ceans: a Diastylis stygia, G. 0. Sars. 



The ventricle of the largest specimen (jj), taken at a 

 depth of 1110 fathoms, contained a large Pasiphae tarda, Kr. 



It is evident trom the food on which these Lyco- 

 des subsist, that most of the well known, true pelagic an- 

 imals, which, at certain seasons, occur in vast quantities 

 near the surface, can descend to the greatest depths in 

 which we have as yet been able, to investigate the Fauna 

 of the Polar Seas ; and that the Lycodes — which must un- 

 questionably be regarded as strongly marked bottom-fishes 

 — do seek means of subsistence on or near the bottom, 

 is shown, for instance, by the circumstance, that the food 

 of L. frigidus comprises forms such as the above-mentioned 

 Cliiridothea. which can hardly ascejid far from the bottom. 



Preserved alive on board in a tub of water, the -in- 

 dividuals displayed but little vivacity, remaining the greater 

 part of the time half rolled up and motionless, much the 

 same as Zoarces riviparns; in swimming, the body is pow- 

 erfully vibrated. On being immersed in spirits, they were 

 exceedingly violent in their movements, and proved rather 

 tenacious of life. 



Distribution. — Assuming the 2 fry-specimens (of 

 which mention has been repeatedly made) that were taken 

 on the outer slope of the great bank, or "sea -bridge." 

 (Havbro). off Lofoten and Helgeland, in Norway, to be
