EUPHAUSIACEA

the present Discovery investigations both on the first commission, outside the area we 

 are at present dealing with, and subsequently, a wealth of material has been collected and 

 an adequate discussion on the distribution of the species must be left for later reports. 

 We may, however, say that the species is a sub-Antarctic and Antarctic form, but not 

 extending into such high latitudes as does E. superba. It appears to be circumpolar in its 

 distribution. 



The Swedish Antarctic Expedition (Hansen, 1913) took a number of specimens of 

 E. frigida from the South Georgia area.

It is a sub-Antarctic species, circumpolar in distribution, having been taken between 

 latitudes 37 47' S and 56 49' S by the following expeditions: Challenger, 1 Belgica, 2 

 National Antarctic (Discovery), 3 Gauss, 4 Scotia 5 and Terra Nova. 6
