while I have not considered the other stations, lying in the 

 western part of the Denmark-Strait, as belonging to the region 

 treated here, but here there is some inconsequence as a few 

 collections were made by both the mentioned expeditions in 

 places lying more eastern, and these are treated here. 



Some genera and species of the groups , not published 

 hitherto in the Ingolf-work, are not yet worked out, and some 

 new species not yet described, and they are therefore in the 

 following only mentioned somewhat summarily. — The material 

 from both expeditions, belonging to the families and orders 

 not yet treated in the Ingolf-work, will be finally treated there, 

 together with the other arctic material. 



The following species are at present known to occur at 

 East-Greenland:
