The general result of this examination of the deep-sea gatherings might be suin- 

 marized as follows: 



The deeper strata with the sal. 35 contain chiefly styliplankton (from the eastern 

 temperate Atlantic and Färöe Channel). This water reaches the surface at St. X. 



The upper strata with 32 — 34 sal. contain at the stations N and O choetoplankton, 

 at the stations M, P, S, T, U trichoplankton. As the latter type has been found this 

 spring ruling in the region east of Greenland and north of Iceland it may derive from 

 that part of the Ocean. 



Organisms, found in the plankton-g-atherings of 



the »Antarctic 1898. 



In the following I give a list of all the organisms, found by me in the plankton- 

 gathering, as well as the dates etc. for every form. B}^ »Temp.» I denote the temperature 

 of the water in centigrades, by »Sal.» the salinity pro mille, by »Fq.» the frequency, whether 

 rr, very rare, r rare, -|- not rare, c common, ce very common, or ccc principal constituent 

 of the plankton. The sign X denotes dead specimens. By »Pl.» I understand the ruling 

 plankton-type viz.: C chtetoplankton, Ng arctic neritic plankton, Nm southern neritic 

 plankton, Ns northern neritic plankton, 5 styliplankton, 2' trichoplankton and Tp tripos- 

 plankton.
