des staa paa Kiuderue hon mod den ovre Raud af Oper- 

 culum paa hver Side i en Triangel 3 Porer; bag Øjnene 

 findes 2 mindre, og atter nedenfor disse 'd større Porer. 

 En stor Pore aabner sig ved den nedre Vinkel af Opercu- 

 lum, hgesom den normale Række ' er tilstede langs Kjæ- 

 verne. 



Farve. Legemets Bundfarve er blegt graaagtig In'iin; 

 under passende Belysning kan skimtes, men højst utyde- ■ 

 ligt, 6 morkero Felter, der i Midten ere lysere, og have 

 enkelte sorte Smaapletter, som danne en Tilnærmelse til 

 de reticulerede Linier, der findes hos L. reticulatus. Tyde- 

 ligst ere disse mørke Felter henad Dorsalen, hvor deres 

 Rande ere næsten sorte, og skarpt markerede. Mellemrum- 

 met mellem Felterne er paa Legemet kun lidet lysere, end 

 Felterne selv. men niesten renhvidt paa Dorsalen og Ha- 

 lespidsen. 



Hovedet har ingen andre Tegninger, end et hvidt 

 Baand, der strækker sig tvers» over Nakken fra den ene 

 Grjællespalte til den anden, og er begrændset af en utyde- 

 lig sort Linie ; iøvrigt er Hovedet blegt rødlig graat, noget 

 lysere, end Kroppen, hvilket ogsaa er Tilfaddet med Pec- 

 toralerne, 



Føde, etc. Individet var en Hun, med umodne Æg 

 i det eneste Ovarium. ^'entrikelen, der var meget nius- 

 culøs. indeholdt et noget fordojet Inilivid af Cottunmlus 

 microps, Coll. (med en Totallæugdc af 110"""), samt Dele 

 af en anden mindre Fisk, der var' stærkei'e fordøjet, og 

 ubestemmelig. 



2 afrundede Udvidelser af Tarmen ved Pylorus kunne 

 opfattes som et Par rudimenta-re Appendices pyloricae. 



TJdbredning. Det eneste hidtil l)ekjendte Exemplar 

 af denne Art optoges fra betydeligt Dyb og iskoldt Vand 

 i Havet nogle Mile vestenfor Nord- Spitsbergen, omtrent 

 under 80" N. B. 



Af den nærstaaende Art L. reticulatus tindes, som 

 ovenfor nævnt, udvoxede Individer fra Grøidand i Musæet 

 i Kjøbenhavn, samt et i Wiener-Musæet, alle erholdte i 

 Aarene 18J3(.) — 40. Af L. perspifMum. Kr., fra Grønland 

 tindes hgeledes et Individ i Musæet i Kjøbenhavn; af L. 

 rossi, Malmgr.. fra Spitsbergen opbevares det eneste Indi- 

 vid i Riks -Museum i Stockholm, og endelig findes Indivi- 

 det af L. cjracilis, M. Sårs. fra Christianiatjorden, i Univer- 

 sitets-Musæet i Christiania. Alle disse 3 sidstnævnte Arter 

 maa, som ovenfor omhandlet, an tåges at udgjøre Ungdoms- 

 formerne af L. reticulatus, eller af L. liUkenii (eller af 

 l)egge ?) 



instance, on the cheeks, near the upjier margin of tlie oper- 

 culum, a triangular figure is formed by pores, three in each 

 of its sides; behind the eyes are two smaller ones, and 

 below these pores three larger ones. A large pore occurs 

 at the inferior angle of the operculum, and the normal 

 series along the jaws is also present. 



Colour. — Tlie ground-colour of the body is a 

 greyisli-ljrown; in a good light, G dusky patches can 

 be discerned. \(\ry indistinctly however; they are lighter 

 in the middle, and marked with a few small black spots, 

 an approximation to the network of lines in L. reticulatus.' 

 These dark patches show most distinct down the dorsal, 

 thoir margins on that Hn being almost black, and sharply 

 detined. On the body, the sjiace lietween the patches is 

 very little ligliter than are the patches themselves, liut on 

 the dorsal and the tip of the tail, it is nearly pure white. 



The only marking on the head consists of a white 

 band stretching across the nape from one gill-opening to 

 the other, and margined by an indistinct black line ; the 

 rest of the head is of a uniform pale reddish-grey, a shade 

 lighter than the body, which is also ^the case with the 

 pectorals. 



Food, etc. — Tlie individual hei-e described was a 

 female, with immature ova in its single ovary. The ventricle, 

 which was very muscular, contained an example of Cottiin- 

 culus nvicrops, Coll., in a ]jartially digested state (total 

 length 110"""), together with parts of a smaller fish, which 

 did not admit of being determined. 



Two globular swellings of the intestine at the pylorus 

 may be regarded as a pair of obtuse pyloric appendages. 



Distribution. — The only example of this species 

 as yet obtained was brought up from a considerable depth 

 in tlie frigid area of the ocean, a few leagues west of the 

 north coast of Spitzbei'gen, in lat. about 80" N. 



Of its nearly related congener L. reticulatus, Reinh. 

 full-grown specimens from Greenland are, as above stated, 

 preserved in the Museum at Copenhagen and in tlie Vienna 

 Mus(Huu. all of which were obtained in tlie decade from 

 1830 to 1840; of L. perspicilJum, Kr., also from Green- 

 land, there is. too, an example in the Museum at Copen- 

 liagen ; of L. rossi, Malmgr. from Spitsbergen, the only spec- 

 imen taken is preserv'ed in the -'Riks Museum'' at Stockholm ; 

 and finally, the specimen of L. gracilis, M. Sars, from the 

 Christiania Fjord, is in the Christiania University Museum. 

 The three last- mentioned individuals must, as suggested 

 above, be regarded as representing tlie early stages of 

 development of L. reticulatus, or of L. liUkenii (or pos- 

 sibly of both).
