25. MARX Description of some Arctic Spiders from the Western Hemi 



sphere (in preparation). 



In the following list are enumerated all of the species which 

 have so far been found and described from the Arctic regions 

 of the globe. I have included the new and undescribed species 

 of my collection. As a large part of the literature was inac 

 cessible to me, it was impossible to compare the different 

 descriptions, and there ma)^ be some species enumerated which 

 are synonyms. 



The species which belong to the Western Hemisphere are 

 marked with an asterisk ; the numbers after the author's name 

 indicate the numbers of the bibliographical list.
