 SPIDERS genital rima and the spinners, and not, as in the last family, immediately in front of the spinners. One species only is indigenous to Great Britain and is very common amongst the foliage of trees in May and June. 11. Anypbeena accmtuata (Walckenaer). Handsworth (F.P.S.). THOMISID^E Spiders with eight eyes, situated in two transverse rows, two tarsal claws and anterior spinners close together at their base. Maxillae not impressed. The crab-like shape and side- long movements of these spiders are their chief characteristics, enabling them to be easily distinguished from the more elongate Drassidte and Clubionidte. 12. Philodromus aureolus (Clerck). 14. Xysticus cristatus (Clerck). Handsworth (F.P.S.). Handsworth (F.P.S.). 13. Tibellus oblongus (Walckenaer). 15. Oxyptlla prattcola (C. L. Koch). Handsworth (F.P.S.). Handsworth (F.P.S.). ATTID^E The spiders of this family may be recognized in a general way by their mode of pro- gression, consisting of a series of leaps. More particularly they may be known by the square shape of the cephalic region and the fact that the eyes are arranged in three rows of 4, 2, 2, the centrals of the anterior row being much the largest. Otherwise the spiders are simply specialized Clubionids with two tarsal claws and other minor characters possessed in common with other members of this family. 1 6. Salticus scenicus (Clerck). 17. Ergane falcata (Clerck). Handsworth (F.P.S.) ; Cannock. Handsworth (F.P.S.). Known also as Salticus ceronatus, BLickwall. PISAURID^ Spiders with eight eyes in three rows of 4, 2, 2 ; the small anterior eyes being sometimes in a straight line, sometimes recurved and sometimes procurved. Those of the other two rows are situated in the form of a rectangle of various proportions and are much larger than the eyes of the anterior row. The tarsal claws are three in number. Pisaura runs freely over the herbage, carrying its egg-sac beneath the sternum ; while Dolomedes is a dweller in marshes and swamps. 1 8. Pisaura mirabilis (Clerck). Known also as Dolomedes, or Ocyale, mirabilis. Cannock. LYCOSIDjE 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 Phauridie, with slight differences. 19. Lycosa ruricola (De Geer). 22. Pardosa lugubrts (Walckenaer). Handsworth (F.P.S.). Cannock. Known also as L. campestris, Blackwall. 23. Pardosa pullata (Clerck). Cannock. 20.
