Distrihufion: 



3Iysis oculafa is, without doubt, the most common among 

 Arctic Mysideans, and at the same time, sometimes occurs 

 in enprmous shoals, rivalling Bhoda inermis and Ni/ctl- 

 jjJianes norvec/ica in its multitude of specimens. In fact, these 

 species supply some Balsenopterids and sea-birds with their es- 

 sential food. 3Iy^is oculafa has been obtained off West G-reen- 

 land, in Smith Sound, ofF Baifin Land, Labrador, and New 

 England, in the Siberian Polar Sea W. of Tajmur Peninsula, 

 Kära Sea, Murman Sea, round Spitzbergen, oiF Finmarken, 

 Iceland, Jan Mayen, and East Grreenland. It must, therefore, 

 be considered an Arctic species; although it was not obtained, 

 according to Stuxberg, during the Vega Expedition E. of 

 Taj mur Peninsula, and although it has not yet been observed, 

 as far as I know, in the Behring Sea or the adjacent parts 

 of the Arctic Ocean, further discoveries in these träets of 

 the sea, hitherto so little explored for zoological purposes, 

 will, I think, prove that it must also be regarded as cir- 

 cumpolar. 



It lives in moderate depths from a few up to 20 fathoms. 

 Such depths as 80—100 — 110 metres, which are recorded above 

 in the list of localities, are the greatest I have found for the 

 species; but, as Hansen has pointed out, it is very probable 

 that it lives pelagic a great deal of the jeåT, and, therefore, 

 the above fignres are not very trustworthy, as the animal 

 might have been taken by the trawl when carried up.
