SPIDERS 



writer has been greatly assisted by the Rev. T. C. B. Chamberlin, M.A., who has collected most 

 indefatigably at North Wheatley and elsewhere near Retford. Dr. G. W. Chaster, of Southport 

 contributed a number of specimens picked up while collecting Coleoptera in Sherwood Forest in June, 

 1904, and among these were several rare species. Specimens have also been contributed by the 

 Rev. A. Thornley, M.A., and Mr. A. H. Pearson, and a few records by Miss E. M. Alderson 

 and Mr. J. T. Houghton. 



In a group so little worked as the arachnida, and one presenting so many difficulties in the 

 identification of the more obscure or closely allied species, it is of the utmost importance that the 

 determinations should be beyond question, and it is therefore gratifying to know that every species 

 enumerated below is vouched for by our highest authority on these creatures, the Rev. O. Pickard- 

 Cambridge, F.R.S., who most generously undertook the examination of the entire collection. 



Lists of the species collected during the seasons 1903 and 1904 have been published in the 

 fifty-first and fifty-second Reports of the Nottingham Naturalist? Society. The arrangement and 

 nomenclature adopted are those of the Rev. O. Pickard-Cambridge in his List of British and Irish 

 Spiders, Monogr. of British Phalangidea, and Monogr. of British Chernetidea.
