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.

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.

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.

 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.
