Jackson has also published illustrated papers on Arachnida in 

 the " Proceedings " (Chester Soc. Nat. Sc, Literature, and Art), 

 1907, and Trans. Nat. Hist. Soc. of Northumberland, Durham, 

 and Newcastle-on-Tyne, n.s., Vol. III., Part I., 1908. Two 

 illustrated papers by Mr. F. P. Smith may also be mentioned 

 (published in 1907 in the Journal of the Quekett Microscopical 

 Club) " On British Spiders of the Genus Lycosa " and *' Some 

 British Spiders taken in 1907. Also a recent paper by the 

 Rev. J. E. Hull (Transactions of the Natural History Society 

 of Northumberland, Durham, and Newcastle-on-Tyne," n.s.,

LIST OF NEW AND RARE BRITISH ARACHNIDA. 



Order ARANEIDEA. 



Family THERAPHOSID^. 



Sub.-fam. ATYPIN^. 



Atypus affinis, Eichwald. 



Two adult males of this spider ; the sole British repre- 

 sentative of the family, were sent to me by Mr. H. 

 Donisthorpe, from Woking, in October, 1907. The spider is 

 found usually in colonies of greater or less extent in their 

 tubular nests ; running down into the earth among the stems 

 of dwarf plants and grass. The female probably never 

 leaves the nest ; but the males, when adult, are usually, or at 

 all events often, met with as wanderers. Though not a rare 

 species, it is certainly a very local one, and one of the most 

 striking in appearance of our British spiders.
