Araneae — Spiders 



The literature dealing with the taxonomy and distribution of spiders is extensive 

 but very scattered and the list of Eur- American species here repesented is prob- 

 ably incomplete. Roewer's catalogue (1942, 1954) is most useful but the records 

 of distribution are quite summary. They were supplemented, for Europe by 

 Simon (1914-37), Reimoser (1919), Holm (1950), for northern Asia by Cha- 

 ritonov (1932, 1936), for North America by Chamberlin & Ivie (1947), Comstock 

 & Gertsch (1948), Gertsch (1949), Hackman (1954), and several other papers 

 listed in the bibliography (p. 126 a.f.). 



Earlier, less complete lists of Eur-American species were published by Berland 

 (1932, p. 379) and Gertsch (1949, p. 259). My preliminary list, compiled from the 

 literature, was sent to Dr. W. J. Gertsch, New York, who kindly corrected and 

 enlarged it to a great extent. I also received many valuable suggestions from 

 Mr. H. Kauri, Lund, and Dr. A. Holm, Uppsala. The final list here given deviates 

 from the opinion of Dr. Gertsch only in so far that a few more species are 

 regarded as introduced; these are marked with a cross in brackets. 



Erigone arctica White and E. atra Bl. have been excluded from the list on the 

 advice of Dr. Holm.
