 A HISTORY OF SURREY PISAURIDJE Spiders with eight eyes in three rows, and three tarsal claws. The first row of eyes consists of four small eyes which are 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. Pisaura runs freely over the herbage, carrying its egg-sac beneath its sternum, while Dolomedes is a dweller in marshes and swamps. 50. Pisaura mirabilis (Clerck). Horsley (F. P. S.), Woking, Bagshot. Known also as Dolomedes, or Ocyalf, mirabilis. LYCOSID^E The members of this family also have eight eyes, similarly situated to those of the Pisau- rida, but the first row is straight. Tarsal claws three. The spiders are to be found running freely on the ground and carrying their 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. 5 1 . Lycosa ruricola (De Geer). This and the four following species are also Horsley, Wimbledon (F. P. S.). known under the generic name Lycosa. A very common species. The male has a 56. Pardosa amentata (Clerck). claw at the end of the palpus. 52. Lycosa terricola (Thorell). Horsley (F. P. S.). Also very common. The male has no claw at the end of the palpus. 53. Lycosa perita, Latreille. Woking, Bagshot. This spider is also known as L. picta. 54. Lycosa accentuata, Latreille. Wimbledon Common, Woking, Bagshot. Known also as Tarentula or Lycosa andreni- vora. 55. Pardosa lugubris (Walckenaer). Horsley, Wimbledon (F. P. S.). 57. Pardosa pullata (Clerck). Horsley (F. P. S.). 58. Pardosa palustris (Linn.). Wimbledon. 59. Pardosa nigriceps (Thorell). Wimbledon, Woking, Bagshot. 60. Pirata hygrophilus, Thorell. Carshalton. 6 1 . Pirata piraticus (Clerck). River Wandle. 62. Pirata latitans (Blackwall). River Wandle. Horsley (F. P. S.). AGELENID^E 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 among the rocks or the herbage, or the chinks in the walls of outhouses, wherever the various species may happen to be found. The habits of Argyroneta are however different. 63. Tegenaria derhamii (Scopoli). Horsley (F. P. S.). 64. Tegenaria atrica (C. L. Koch). Horsley (F. P. S.). 65. Tegenaria parietina (Fourcroy). Wimbledon. This spider is known also as T. guyanii, and is the T. domestica of Blackwall. 66. Tegenaria silvestris, L. Koch. Horsley (F. P. S.). 67. Agelena labyrinthica (Clerck). Wimbledon, Woking. A very common spider, making a sheet-like web on the herbage with a funnel-shaped tubu- lar retreat. 68. Hahnia elegans (Blackwall). River Wandle. 69. Argyroneta aquatica, C. L. Koch. Wimbledon. This is the well-known water spider which makes a silken nest beneath the surface and swims and dives freely, hatching out its young within the nest. 70. Caelotes atropos, Walckenaer. Horsley (F. P. S.). 71. Textrix denticulata (Olivier). Horsley (F. P. S.). 182
