A much larger species, shiny black with pale mark- 

 ings, found in cellars and also beneath rocks and 

 stones on the coast, or in crevices of banks in the open 

 country. Known also under the name Ciniflo. 



CHERNETES 



CHELIFERIDAE 



Out of twenty species of false-scorpions indigenous 

 to Great Britain only one is recorded from this 

 county. The various species can be found amongst 

 moss and dead leaves, or beneath stones and the bark 

 of trees. They are unmistakeable 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 dcaridea.
