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



Føde. I ^'entrikeleu af et mindre Exemjjlar fra 

 Magdaleuebay fandtes fintfordelte Crustaceer. der ikke lode 

 sig bestemme. Selv tjener Arten, ifølge Mabngrens Obser- 

 vationer paa Spitsbergen i 18(J1, til Føde for flere Fugle,

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

 tudinal patches occHr. too. in the middle of the dorsal tin. 

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

 dirty greyish-yellow, cltisely resembling that which the skin 

 of fishes assumes in the stomach of a fis'h some time after 

 tlie process of digestion has commenced. 



In one of the younger jiidividuals. the pyloric appen- 

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



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

 imens, fi-om Magdalene Bay. were found minute fragments 

 of crustaceans, which did not admit of being determined. 

 According to Malmgren. this species is preyed upon by 

 several birds, more» especially Uria g'ryJle. 



Udbredelse. L. mcdins er liidtil blot fundeai ved 

 Grønlands og Spitsbergens Kyster. I 1835 anmeldtes den 

 af Reinhardt for Videuskabs-Selskabet i Ivjøbenhavn fra 

 Grønland; senere er den hjembragt i adskillige Individer 

 fra- Spitsbergen under de svenske Expeditioner, og den an- 

 gives at forekomme talrigere her, end de øvrige Arter. 

 Dette synes ogsaa at kunne bekræftes ved Nordhavs-Expé- 

 ditionen. som erholdt den. som ovenfor nævnt. i 7 Inxliyi- 

 der fra et Par forskjellige Localiteter paa denne Øgruppe. 

 Yed Fimnarken eller paa andre Steder af Ishavet ■ er den 

 hidtil ikke aimivet som funden.

Distribution. ■ — . L. medius has hitherto been ob- 

 served on the shores of Greenland and Spitzbergen only. 

 In 1835. Reinhardt' communici\ted its occurrence on the 

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

 hagen; since then, individuals have b^en rejDeatedly taken 

 off Spitzbergen.. on the 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.
