 parallel rows, the laterals being in contact. The calamistrum and cribellum are present, and 

 there are three tarsal claws. They construct a tubular retreat with an outer sheet of webbing, 

 which is covered with a flocculent silk made with the calamistrum and threads from the 

 cribellum.

CHERNETES 

 CHELIFERID^ 



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

 only one has been taken in this county. 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. The 

 single species which has occurred in the coimty was taken by Mr. Freston and myself in the 

 environs of Ormesby Broad. 



189. Chthonius rayi, L. Koch.
