SPIDERS 1 1 6. Amaurolws similis, Blackwall. Mawnan ; Portscatho. A very common species in greenhouses, stables, and other outhouses. The males may often be found wandering about the walls of dwelling-houses after nightfall. Known also under the name Ciniflo. 117. Amaurobius Jerox, Walckenaer. Whitsand Cliffs (G. C. B.) ; Liskeard ; Port- scatho. 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. 1 1 8. Chthonius rayi, C. L. Koch. Whitsand Bay (G. C. Bignell). OPILIONES The Harvestmen are spider-like creatures with eight long legs, the tarsi long and very flexible. Eyes sim- ple, two in number, situated on each side of an eye- eminence. Body not divided into two distinctive regions by a narrow pedicle, as in the spider's. Abdomen segmentate ; breathing apparatus consisting of tracheal tubes with external stigmata. TROGULIDAE 119. Anclasmocepbalus cambridgji, Westwood. (O.P.-Cambridge). Known also as Trogulus cambridgii.
