SPIDERS 



DICTYNID^ 



The spiders belonging to this family possess three tarsal claws, and the eyes, eight in 

 number, situated in two transverse rows, the laterals being in contact. The cribellum (or 

 extra pair of spinning organs) and the calamistrum (a row of curving bristles on the protarsi 

 of the fourth pair of legs) are present in all members of the family. They construct a tubu- 

 lar retreat with an outer sheet of webbing, which is covered with a flocculent silk made with 

 the calamistrum from threads furnished by the cribellum.

CHERNETES 



CHELIFERIDiE 



Out of twenty species of false scorpions hitherto recorded as indigenous to Great Britain 

 only two have been taken in this county. That this small number is simply due to lack of 

 investigation may be gathered from the fact that fourteen species of the order have been taken 

 in the county of Dorset. The various species can usually be found amongst moss and dead 

 leaves or beneath stones and the bark of trees. They are unmistakable on account of their 

 possession of a pair of forcipated palpi, like those of the true scorpion. These are usually 

 extended wide open when the Arachnid is alarmed while it hastens backwards to take shelter. 

 In spite of this scorpion-like appearance these little creatures are much more nearly allied to 

 the mites or Acaridea.
