Lt is my intention in the followinc^ pages to give an enu- 

 meration of the crustaceans collected on the Swedish Arctic 

 Expeditions in the siimmers of 1898 and 1899. Both were 

 directed by Professor A. G. Nathorst. The chief purpose of 

 the first was to exphjre the hitherto almost unknown islands 

 situated east of Spitzbergen, and generally called vKing 

 (^harles Islands >; but, besides that. a steady lock-out for 

 Andrée or, eventually. his relief entered as an almost ini- 

 portant feature in the program. The last point was that 

 which first gave the inipnlse to the East G-reenland Expedi- 

 tion 1899. As we all know, the result of all researches for 

 Andrée and his brave companions was futile; no traces of 

 that nnsnrpassed expedition was to be found. 



But, for science, both expeditions gained the most im- 

 portant results as nearly every branch of natural sciences 

 was represented by specialists. The zoological collections are 

 not yet worked up; but, when examined and determined, they 

 will, I think, prove to be very great. During the expedition 

 of 1898 I led the operations of trawling and dredging, and 

 Mr. J. Gunnar Andersson, of ITpsala, the collecting of piano- 

 ton. Zoologist in 1899 was I. Arwidsson, B. A,, of Upsala. 



In 1898 I dredged and trawled on 42 stations, located all 

 round the archipelago of Spitzbergen, and between Spitz- 

 bergen and Norway. On a few days trip westwards to the 

 East Greenland pack-ice, I got some chances of trawling on 

 great depths, 2000 — 3000 meters. 



The expedition of 1899 spent the most time in ex- 

 ploring the unknown coast of East Greenland between lat. 

 70" — 75" N. ; thence the stations are mainly situated along 

 that coast where zoological collections have only once been 

 made (German Expedition 1869—70). But the expedition 

 visited also that isolated volcano, Jan Mayen, where J\Ir. 

 Arwidsson found opportunities of dredging.^ 



1 I have also worked out a small collection of Arctic Crustacea made 

 at Spitzbergen last summer by Mr. Fr. "Wulff, B. A., of Lnnd, on board one 

 of the steamers of the Swedish-Russian Commission for measuring latitudes.
