Individerrie strække sig en Del saadanne af lys brunlig 

 Farve laugs hele Legemet, ligespm der tindes Here brun- 

 sorte Længdepletter paa Midten af Dorsalen. Flere af de 

 mindste Individer derimod ere mosten uplettede, og have 

 en smudsig graagul Bundfarvej der næsten ligner den, som 

 Fiske pleie at antage, naar de i nogen Tu l have væ.ret ud- 

 satte for Fordøjelsen i en Kiskeniave. 



Appendices pyloricae befandtes hos et at' de yngre 

 Individer at være 4 i Antal. de 2 kortere, end de øvrige. 



Føde. I Ventrikelen af et mindre Exemplar fra 

 Magdalenebay fandtes tintfordelte Crustaceer, der ikke lode 

 sig bestemme. Selv tjener Arten, ifølge Malmgrens Obser- 

 vationer paa Spitsbergen i 1861, til Føde for tiere Fugle, 

 især Una grytte. 



Udbredelse. L. medius er hidtil blot fonden ved 

 Grønlands og Spitsbergens Kyster. I 1835 anmeldtes den 

 at' Reinhardt tor Videnskabs-Selskabet i Kjobenhavn fra 

 Grønland; senere er den hjembragt i adskillige Individer 

 fra Spitsbergen under de svenske Expeditioner, og den an- 

 gi ves at forekomme talrigere her. end de øvrige Arter. 

 Dette synes ogsaa at kunne bekræftes ved Nordhavs-Expe- 

 ditionen, som erholdt den. som ovenfor nævnt, i 7 Indivi- 

 der fra et Par forskjellige Localiteter paa denne Øgruppe. 

 Ved Finmarken eller paa andre Steder af Ishavet er den 

 hidtil ikke aneivet som funden.

isli spots, extending along the whole of the body; longi- 

 tudinal patches occur, too, in the middle of the dorsal tin. 

 Some of the youngest individuals, however, are of a uniform 

 dirty greyish-yellow, closely resembling that which the skin 

 of tislies assumes in the stomach of a tish some time after 

 the process' of digestion has commenced. 



In one of the younger individuals, the pyloric appen- 

 dages were 4 in number, 2 shorter than the others. 



Food. — In the stomach of one of the small spec- 

 imens, from Magdalene Bay. were found minute fragments 

 of crustaceans, which did not admit id' being determined. 

 According to Malmgren, this species is preyed upon by 

 several birds, more especially Una grylle. 



Distribution. — L. medius has hitherto been ob- 

 served on the shores of Greenland and Spitsbergen only. 

 In 1835. Reinhardt communicated its occurrence on the 

 coast' of Greenland to the "Vidensk.-Selskabet" in Copen- 

 hagen: since then, individuals have been repeatedly taken 

 off Spitzbergen, on tbe several Swedish Expeditions to that 

 region, where it is said to be more numerous than any of 

 the other allied species. This statement would appear cor- 

 roborated by the experience of the North Atlantic Expe- 

 dition, on which seven specimens were obtained. On the 

 coast of Finmark, or in other parts of the Polar Sea. it 

 is -not as vet known to have been observed.

 Ihr palatine hones. Length of head in young individuals is 

 to total length as 1 to o'/, . in adults as Hod. Upper jaw, 

 slightly projeefini/ beyond lower, reaches bad- to the middle 

 of tin' rye or its posterior margin. The 2 — i f 'r st dorsal rays 

 short, and free at base. Pectorals comparatively large, length 

 to total length as 1 to 6 — 7; the 5 or 6 hneer rays sud- 

 denly elongated. Caudal free at base: posterior margin
