BRITISH SPIDERS. 



In order to give some general idea of the different kinds of 

 spiders that inhabit Britain, we have next displayed a series of 

 examples and illustrations of the different famiHes and most of the 

 genera of British spiders. The arrangement is that of the Rev. 

 O. P. Cambridge, published in the Linnean Society's Transactions 

 1874, which seems in some respects an improvement upon that 

 adopted by Mr. Blackwall, our great British arachnologist, in his 

 important work, "The Spiders of Great Britain and Ireland," 

 published by the Ray Society. 



Family MYGALID^. 

 Sub-Family Theraphosid^. 

 Atypus sulzeri {Latr.). — See Case IV., No. 14. 



Family DYSDERID^. 



The Dysderidse, along with the genus Scytodes, which will 

 be found further on, are the only British spiders that have six 

 eyes, the rest all having eight, and they have consequently been 

 placed in a separate division by themselves, but they are 

 clearly nearly united to the genus Atypus, on the one hand, 

 and the Drassid^ on the other, which shows that too much 

 value must not be placed upon the number of eyes as 

 a character of natural affinity. The Dysderidse live in holes 

 in the ground and crevices in rocks and walls or in cells and 

 tubes of silk constructed under stones and take their prey by 

 hunting.
