T. P. CLEVE. PLANKTON COLLECTED BY THE SWEDISII EXPEDITION TO GKEENLAND. 



The plankton is essentially the same as was found in the deeper strata in the S.E. 

 above the slope of the 200 metre plateau towards the Norwegian depth. Thus the same 

 kind of plankton ruled on the greater depths of the nothern Atlantic from Greenland to 

 the Scoteh and Norwegian coast banks. Most characteristic forms are Calanus hyperboreus, 

 Chiridius armatus, Euchata norvegica, Metridia longa, Oncwa eonifera, O. minuta, Con- 

 choecia borealis, Q. elegans, Krohnia /utmata and Sagitta arctica. 



4. Samples collected in August. 



During that month the »Antarctic» visited the fjords of E. Greenland, between 71° 

 and 73° N. and there were collected a smaller number of samples, the examination of 

 which gave the following resnlt.

The above list shews a very poor plankton, in part from the intrnsion of oceanic 

 water, containing Oithona similis, Chcetoceros decipiens and Ceratium arcticum. 



Outside the fjords some samples were collected during the last days of August at 73° 

 15' N. 21° 25' W. (temp. 4,35, sal. 28,«4) and at 72° 28' N. 16° 13' W. (temp. l,i, sal. 29,oo). 

 The first named was sterile, the latter contained Oithona si milis r and Limacina kelicina c.
