374 K. STEPHENSEN. } 
Very much the same applies to the distribution of Calanus finmar- 
chicus (Conspectus p. 308); at depths of 200m. and beyond, however, 
it amounts to abt. 80—90 °/o. 
B. Boreal (Atlantic) Plankton species. 
(K. St., Danmark Exped. p. 609; Conspectus p. 421). 
In the Danmark Exped., 52 Atlantic Plankton Malacostraca are 
mentioned; Mysis mixta should be erased, as beg a bottom form, while 
on the other hand, Idotea metallica should be reckoned to the plankton 
and not to the bottom fauna. 
Of these, the “Rink” found 14 species in all, viz: 
x Pasiphaé tarda (Conspectus p. 47) 
Meganyctiphanes norvegica (ibid. p. 55) 
Thysanoessa inermis (ibid. p. 56) - 
— longicaudata (ibid. p. 57) 
— Raschii (ibid. p. 59) 
x Boreomysis arctica (ibid. p. 67) 
Hyperia galba (ibid. p. 97) 
—  medusarum (ibid. p. 96) 
Blihensisto compressa (ibid. p. 102) 
— bispinosa (ibid. p. 104) 
Parathemisto oblivia (ibid. p. 104) 
x Scina borealis (new for Greenland). 
Aega ventrosa (Conspectus p. 233) 
besides (of Entomostraca) x Podon Leuckartii. 
Of these, only the 4 marked x are known exclusively from the 
Atlantic region. The others should mainly be called Atlantic, having 
their principal occurrence in the warm atlantic water; they have, however, 
also been found living under purely arctic conditions, and cannot there- 
fore testify to the character of the fjord fauna. As however, the Atlantic 
water (> 3.5°, > 3.5/9, salinity) does not appear until a depth of 
200—250 m. below the surface, (corresponding to 400—500 m. w. with 
the rmgtrawl) we may disregard such species as were found nearer the 
surface. The distinctly Atlantic species Pasiphaé tarda, Boreomysis 
arctica and Scina borealis were taken in these deep layers, whereas 
Podon Leuckartii was found at the surface. 
Zoogeographical character of the separate fjords. 
The present investigations are chiefly concerned with the deeper 
parts of the fjords, as the littoral fauna, being common to Greenland 
generally, is of minor importance to the question at issue. The following 
pages, therefore, deal only with the stations in 200m. of water and
