 SPIDERS LYCOSID^ The members of this family are to be found running freely over the ground, and carry- ing the egg-sac attached to the spinners. Many of the larger species make a short burrow in the soil and there keep guard over the egg-sac. Eyes and tarsal claws as in the Pisaurida, with slight differences. 13. Lycosa cuneata (Clerck). 14. Lycosa perita, Latreille. Wolcingham (C.W.P.) Wokingham (C.W.P.) AGELENID^ Spiders with eight eyes, situated in two straight or more or less curved transverse rows. Tarsal claws, three. The species of this family spin a large sheet-like web, and construct a tubular retreat at the back of it, which leads to some crevice amongst the rocks or in the herbage, or in the chinks in the walls of outhouses and barns, wherever the various species may happen to be found. The habits of Argyroneta, the water spider, are however quite different. The posterior pair of spinners is much longer than the others in the more typical genera of this family. I"]. Tegenaria derkami (Scopoli). Windsor (A.P.) A very common species everywhere. 1 8. Agelena labyrinthica (Clerck). Windsor (A.P.) Abundant, forming large sheet-like webs 15. Tegenaria atrica, C. L. Koch. Windsor (A.P.) 1 6. Tegenaria parietina (Fourcroy). Windsor (A.P.) Abundant in the London district generally. Known also as T. guyonii and T. domestica. on the herbage, with a funnel-shaped tubular retreat. The spiders included in this family have eight eyes, situated in two rows, the lateral eyes of both rows being usually adjacent, if not in actual contact, while the central eyes form a quadrangle. The tarsal claws are three, often with other supernumerary claws. The web is either an orbicular snare, as in the case of the ' common garden spider,' or consists of a sheet of webbing, beneath which the spider hangs and captures its prey as it falls upon the sheet. This immense family includes those usually separated under the names Epeiridts and Linyphiidts. Meta segmentata (Clerck). 26. Araneus umbraticus, Clerck. Windsor (A.P.) Windsor (A.P.) Very abundant. Known also as Efeira 2?- Araneus sclopetarius, Clerck. 19 inclinata, Blackwall. 20. Meta meriana (Scopoli). Windsor (A.P.) Not uncommon. Known also as Epeira antriada, Blackwall, and a striking variety as E. ce/ata, Blackwall. 21. Tetragnatha extensa (Linnaeus). Windsor (A.P.) Most abundant and generally distributed. 22. Cyclosa conica (Pallas). Windsor (A.P.) 23. Zilla x - notata (Clerck). Windsor (A.P.) 24. Araneus cucurbitinus, Clerck. Windsor (A.P.) 25. Araneus diadematus, Clerck. V/indsor (A.P.)
