S. septentrioi^alis Oestr. + 



Tracliyneis aspera var. intermedia Grun. rr. 



C. Fresh loater species: 



Cymhella ventricosa KÜTZ. 1 specimen. 

 Eunotia incisa Greg. 1 specim. 

 E. robusta var. papilio Grun. 1 specim. 

 Navicula Reinhardtii Grun. 2 specim. 



Besides, there was fouiid one fragment of Paralia ornata 

 Grun. (Tertiary fossil?). 



The marine species are in all samples tlie same as were 

 found by the Vega Expedition on the drift-ice at Cape Van- 

 karema and by the »Antarctic»-Expedition in 1898 at 78' 22' N. 

 2° 45' W., so there cannot be any doubt that they are of the 

 same origin. The samples 173 and 176 contained a great per- 

 centage of fresh water forms, which were only very rarely seen 

 in the other samples, and besides much more mineral detritus. 

 It is to be assumed that these fresh water forras have been 

 transported from the land by winds.
