l)laiice l)el\vcHMi thein. Aliiiosl Ihc saino species ol" Tiniinnodca occur 

 in both places, hul it is leinarkahle llial three species ol" Tintiu- 

 nopsis (viz.: T. nitida Bdt., T. sinnata Hdl. and T. sacculiis Hdl.) des- 

 cribed by Brandt from the Kaiajak Ijord, have not been seen in 

 our samples; perhaps the more northern latitude of Danmarks Havn 

 (6 — 7° higher) and the thereof resulting more strictly arctic condi- 

 tions of life may have some relation to the absence. 



Besides the Tindnnodea which are best taken by means of sur- 

 face hauls with fine-meshed nets, the samples contain but few Pro- 

 tozoa, viz.: two Radiolaria, one Foraininifera and the resting stage 

 of an unknown organism. 



The Radiolaria have, taken in general, not their home in the 

 surface water, and, no doubt, vertical hauls would have given many 

 more species. Glohigerina biilloides, one of the few pelagic Foramini- 

 fera, is an atlantic organism. Lastly we have the peculiar resting 

 stage, Hensen's "Sternhaarstatoblast" which has hitherto been known 

 only from the Baltic and the occurrence of which consequently is 

 of some zoogeographical interest. Nothing is known on its place in 

 the system, and it may perhaps be a stage of some Metazoon. 



In the following papers remarks on the species mentioned in 

 the list and on their occurrence in the East-Greenland Sea are to
