The following paper on the Arachnida of the Expedition, by Nathan 

 Banks, Division of Entomology, U. S. Department of Agriculture, 

 was originally published in the Proceedings of the Washington Acad- 

 emy of Sciences, vol. u, pp. 477-486, Dec. 20, 1900. It is here 

 reprinted from the same electrotype plates, so that it may be quoted 

 exactly as if it were the original. The original pagination has been 

 preserved and transferred to the inner or hinge side of the page, 

 where it is enclosed in brackets, thus [478] ; while the consecutive 

 pagination of the present volume has been added in the usual place. 

 In the plate the original number and running headline, slightly abbrevi- 

 ated, have been preserved [in brackets] , while the volume designation 

 and serial plate number have been added in the usual place. The 

 original text references to the plate are unchanged. The present head- 

 piece and title have been substituted for the running heading of the 

 Academy's Proceedings and the original title, which was : Papers 

 fro)n the Harriman Alaska Expedition, XI. Entomological Re- 

 sults (j) : Arachnida. No other alterations have been made.
