SPIDERS 



ARACHNIDA ' 



Spiders 



The following list of the spiders of the county of Durham is almost entirely due to the 

 researches of the Rev. J. E. Hull, of North Shields, who in 1896 published a 'Catalogue of the 

 Spiders (Araneidea) of Northumberland and Durham.' * Out of a total of about 534 species of 

 spiders recorded for Great Britain and Ireland only 1 12 species have been taken in the county of 

 Durham, while of the Pitudo-scorpiones and Opi/iones there are none at all recorded, so far as I 

 can make out. 



There is no doubt, however, that the number of spiders would be much increased if a 

 diligent search were instituted, for there are plenty of species which one can be quite sure must 

 inhabit a district whose physical characters are of the kind furnished by this county. 



Of those recorded the following are worthy of special mention either on account of their 

 rarity or being of particular individual interest : Osnops pulchtr ; Cryphaeca diversa ; Cicurina 

 cinerea ; Meta menardi ; Centromerus sylvaticus ; Micryphantes cornigera ; Dicymbium tibiali ; 

 and Euryopis blackwallii.
