SPIDERS 

 ARACHNIDA 



Spiders, etc. 



So very little research has been made in connection with members 

 of this order, so far as the county of Norfolk is concerned, that it is not 

 possible to consider the following account of the spider-fauna of the 

 region under consideration in any respect a full one. For while 550 and 

 upwards of species are recorded from England and Wales, 195 species are 

 all that have been placed to the credit of Norfolk. 



That it ought to prove a rich locality however, when thoroughly 

 well worked, cannot be doubted, if we remember that it consists of wild 

 heather lands, semi-cultivated woodland districts and rich fen-land regions 

 towards the east coast. 



It is scarcely possible to point to any one tract as more likely to 

 repay research than another, except that in a general way wild unculti- 

 vated districts are much more prolific than those that are highly cultured. 

 Yet even in the latter case, where isolated areas of wild growth and forest 

 land occur, with cultivated land on all sides, these oases are often found 

 to be more plentifully inhabited than even huge tracts of primeval forest. 



Of the 188 species of spiders recorded those deserving special men- 

 tion on account of their variety are Attus cartel's, Lycosa spinipalpis, Par- 

 dosa farrenii, Pholcus phalangioides, a species confined as a rule to the 

 more southern counties, Steatoda sticta, Asagena phalerata, Hilaira uncata, 

 Mengea scopiger, Araneus patagiatus and Clubiona neglecta. 



The localities given in the following list are well authenticated, and 

 the initials of those who collected the specimens or recorded their occur- 

 rence are added. 



The greater part of the species recorded were collected by H. W. 

 Freston, Esq., of Kersal, Manchester, many by Lord Walsingham and 

 others by Messrs. Linstead, F. P. Smith, James Edwards and the present 

 writer. 



In cases where the generic or specific name quoted is not that under 

 which the spider has usually been recognized in the works of English 

 authors, a note has been added calling attention to the fact. 



ARANE^ 



ARACHNOMORPH^ 



DYSDERID^ 



Spiders with six eyes and two pairs of stigmatic openings, situated close together on the 

 genital rima ; the anterior pair communicating with lung books, the posterior with tracheal 

 tubes. Tarsal claws, two in Dysdera, three in Harpactes and Segestria. 



I. Dysdera camhridgii, Thorell. form, orange legs, dark mahogany carapace 



and pale clay-yellow abdomen. The palpal 

 bulb of the male has no cross-piece at the 



(O. P.-C.) ; Scratby Cliffs (H. W. F.). 



Not uncommon under stones and bark of apex 

 trees, where it lurks within a tubular retreat. This spider is also known as D. eryth 



The spider is easily recognizable by its elongate Blackwall.
