This part of the zoological collections is not large, but is 

 however of a certain interest from zoogeographical and biological 

 points of view although it contains but two species, namely 



Rossia glaucopis Loven. 



1 specimen 23 /e N. of Hopen Eiland, 77° 25' N, 27° 30' E; 1 ) 

 depth 160 ra. yellowish brown clay; temperature — 1,71° C. 



2 specimen 25 /s in the entrance to Liefde Bay, 79° 47' N, 

 14° 28' E; 1 ) depth 140 m.: stones and red algas. (Dr. A. Ohlin.) 



The first of these is quite typical showing the prominent 

 white warts in great number. The two latter represent the 

 variety which by Verrill has been named: sublevis, but which 

 may be nothing eise than less strongly contracted specimens of 

 R. glaucopis. 2 ) 



This species seems to be rather widely distributed in arctic 

 regions. Kükenthal and Walter found it on the eastcoast of 

 Spitzbergen 3 and the Norwegian North Atlantic Expedition 



*) From Greenwich.
