ANYPHiENIDiE The spiders of this family resemble those of the Cluhionida in most respects, except that the tracheal stigmatic openings beneath the abdomen are situated about midway between the 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. 29. Anypheena accentuata (Walckenaer). (James Edwards). THOMISIDiE Spiders with eight eyes, situated in two transverse rows, two tarsal claws, and anterior spinners close together at their base. Maxillas not impressed. The crab-like shape and side- long movements of these spiders are the chief characteristics which enable them to be dis- tinguished from the more elongate DrassidiS and Cluhionida. 31 32 30.
