founri along the Færoes, but Ihe following lisl and hildes are more 

 particularly valuable, because they represent so long a period ns 

 si\ yearSj during which gatherings have been made at shorter and 

 longer intervals. Tbey form a pendant to the investigations of 

 several years standing of the Norwegian Sea, the North Sea and Ihe 

 Skagerak carried ont by Norwegian and Swedish investigatois '. 



Excepting the above-mentioned paper by Cleve, very little has 

 been published particularly with regard to the Færoese plankton; 

 there are only two short papers by G. Pouchet 2 , who visited 

 Thorshavn in August (from the 12th to the 24th) 1890. He made 

 daily gatherings, and studied the living organisms, especially Gijm- 

 nodinium pseudonoctiluca, diseovered by him, which appears to be 

 extremely interesting as it forms a link between the Peridiniaceae 

 and the Cgstoflagellata ; unfortunately it has never been observed 

 by others; it can only be studied while living; as having no cell- 

 walls it beeomes misshapen and indistinguishable when preserved 

 together with other organisms. In his note in »Comptes Rendus« 

 he gives some general features of the plankton. It was very uni-
