fflellem Alger nser Stranden. Udenfor Norge er den no- 
teret fra Kattegat, 0sters0er de britiske 0er og den mur- 
nianske Kyst. 
58. Mysis mixta, Lilljeborg. 
Exemplarer af denne Art blev under Expeditionen 
tagne i Saltenfjord, ved Rest, i Kjosen og red Reikjavik 
paa Island. 
Arten er nordlig udbredt til Gronlaiul (M. 1 at/ tarts 
Kroyer), Nordamerikas 0stkyst og den murmanske Kyst og 
derfor utvivlsomt at betragte som en Eegte arktisk Form, 
skjondt den gaar sydlig til Ohristianiafjorden, Kattegat og 
0 sters 0 en. 
59. Mysis oculata, (Eabr.) 
Denne hoinordiske Form, der kun af og til er ob- 
serveret paa en enkelt Lokalitet ved vore Kyster (Yar- 
angerfjorden), fandtes under Expeditionen i enorme Masser 
saavel ved Jan Mayen som ved Spitsbergen (Advent bay, 
Magdalenebav og Norske 0er). Et enkelt Exemplar er- 
holdtes ogsaa i Havnen ved Reikjavik. 
Arten er udbredt til Grenland, Nordamerikas 0stkyst, 
Polaroerne, Sibiriens Ishav og det lcariske Hav, folgelig 
circumpolar.

Exemplarer under Expeditionens lste Togt ved Husp paa

Gorges Kyster. 
in Kjosen, between Algae, near the shore. Beyond the 
limits of Norway, the form has been recorded from the 
Oattegat, the Baltic, the British Islands, and the Murman 
coast. 
58. Mysis mixta, Lilljeborg. 
Specimens of this form were taken on the Expedition 
in the Saltenfjord, at Rost, in Kjosen, and at Reikjavik, 
Iceland. 
Northward the distribution of the species extends as 
far as Greenland (M. latitam Kroyer), the east coast of 
North America, and the Murman coast; hence, the animal 
must unquestionably be regarded as a true Arctic form, 
though occurring southward down to the Christianiafjord, 
the Oattegat, and the Baltic. 
59. Mysis oculata, (Eabr.) 
This Arctic form, observed, as a rare occurrence, in 
but one locality on the Norwegian coast (the Varangerfjord) 
we met with during the course of the Expedition in pro- 
digious numbers alike oft the coast of Jan Mayen and at 
Spitzbergen (Advent Bay, Magdalena Bay, and the Nor- 
wegian Islands). A single specimen was also secured in 
the harbour of Reikjavik. 
The species being distributed up to Greenland, the 
East coast of North America, the Polar Islands, the Si- 
berian Polar Sea, and the Kara Sea, is circumpolar. 
60. Mysidella typica, G. O. Sars. 
Of this diminutive, peculiar Mysidian, two specimens 
were taken, on the 1st cruise of the Expedition, off Huso, 
at a depth ranging from 80 to 100 fathoms. As yet, the 
form has not been observed elsewhere than off the coast 
of Norway.
