CHERNETES CHELIFERIDiE 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 usxially 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 county was taken by Mr. Freston and myself in the environs of Ormesby Broad. 189. Chthonius rayi, L. Koch. Ormesby Broad (H. W. F.). 181
