The arrangement and nomenclature of the families and 

 genera here adopted are mainly those of Simon's ' Histoire 

 Naturelle des Araignees,' 2nd edition. For the synonymy of 

 the various species reference may be made to the Rev. 0. 

 Pickard Cambridge's ' List of British and Irish Spiders,' 

 November, 1900, any departure from it being noted in the 

 text, so that any spider may be readily traced. With the ex- 

 ception of eleven, which, however, rest on fully recognized 

 authority, I have either collected or seen examples of all the 

 Yorkshire species, but in a matter of this kind, accuracy being 

 absolutely essential, I have not always relied on my own 

 knowledge and acumen, but when occasion arose, submitted 

 specimens for attestation or confirmation, and, in my novitiate, 

 for identification, to the Rev. O. Pickard Cambridge and Dr. 

 Jackson, to whom my very best thanks are therefore due, as 

 well as to the following for authenticated records or collections 

 or both : Messrs. Stainforth and Parsons, Hull ; W. P. Winter, 

 vShipley ; G. B. Walsh, Linthorpe ; J. W. H. Harrison, Middles- 

 borough ; Rev. R. A. Taylor, now of Burnley ; S. Margerison ; 

 and to the Right Hon. the Earl of Dartmouth, J. J. Burton 

 Esq., Nunthorpe, Sir. J. M. Spencer-Stanhope, Cannon Hall, 

 for access, freely granted, to woods owned by them in various 

 parts of the county.
