1 Allerede under det første Aara Expedition, i 1876, erholdtes 

 omtrent paa samme Sted et Exemplar af eii Lydodes, der ved et Uheld 

 blev bortkastet. Prof. Sars erklærer, at det utvivlsomt har tilhørt 

 samme Art, som ovenfor er benævnt l. muraena.

Food etc. — The largest of the specimens was a 

 female, with immature ova in the single ovary. The some- 

 what smaller, fully sealed individual, was a male. 



The ventricle ol' the female contained exclusively 

 parts ol' Themisto UbeUtda, Blandt; thai of the male con- 

 tained likewise fragments nl' Themisto, and also an example 

 of the diminutive [sopod Xniaioii/sriis bicuspis, lately described 

 by Gr! < >. Sars. and ol' which one or two individuals md\ 

 bad previously been known. 



Distribution. Of L. mureena 4 specimens have been 

 obtained up to the present time, all ol' which were brought 

 up from a considerable depth in the cold area, far from 

 hind. The first was taken on the second voyage of the 

 Expedition, in 1877. on the banks off Helgeland. 1 in Nor- 

 way, accordingly south of the Arctic circle: the remaining 

 three were brought up. on the last cruize, in 1878. from 

 the depths off Beeren Eiland and Spitzbergen, — as far 

 north as deep-sea dredging has been undertaken (80°).

 locality about, an example of a Lycodes had been obtained, which was 

 afterwards unintentionally thrown away. Professor Sars states it to have 

 been Unquestionably of the same species as that here termed/., mtinnm.
