I. Some Desmids from North Australia. 



II. Freshwater Algce and Plankton from Finmark. 



III. The Germination of the Zoögonidia of Stigeoclonium tenue. 



IV. Besting Spores of Pediastrum. 



Under this title I am going to publish various observations 

 I have made on the Algae and the Plankton. 



They will include such as lists of species in smaller collec- 

 tions submitted to me for investigation, essays and observations 

 on biological and ecological matters, and so on. — On the whole, 

 smaller contributions, which are not important enough to be 

 dealt with in separate papers. 



The following contributions will chiefly deal with some 

 collections from various parts of the World, and with the life- 

 history of some microphytes. 



I. Some Desmids from North Australia. 



In the year 1894, Dr. Knut Dahl undertook an expe- 

 dition to the North of Australia principally for collecting zoolo- 

 gical objects.
