Report on the Malacostraca colleeted 
by the "”Tjalfe”-Expedition, under the direction 
of cand. mag. Ad. $. Jensen, especially at 
W. Greenland. 
By 
K. Stephensen. 
During the fisheries-investigations carried out by Mr. Ad. S. 
Jensen in the Greenland seas, especially at S. W. Greenland, with 
the Tjalfe” in the summers 1908 and 1909, a considerable 
material of Crustaceans was collected, Especially bathypelagic 
species and larvæ of such species are richly represented in the 
collection, this expedition standing foremost among those, by which 
such material has been brought to light. Itwas, however, by no means the 
whole material of Crustaceans, which was preserved, particularly of 
the more common species, the main object of the expedition being 
fisherjes-investigations, not a general survey of the marine fauna. 
The material contains in all 84 species and 6 species of larvæ. 
The following species are new to science. 
Cleonardo microdactylus. (No. 57). 
Eusirus Tjalfiensis. (No. 67). 
Munneurycope Tjalfiensis. (No. 80). 
Holophryxus Acanthephyræ. (No. 84). 
Besides these the following species are new to Greenland :
