• A family of spider-like arachnids, constituting the order Galeodea or Solpugidea or Solifugæ; the weasel-spiders. They have a segmented cephalothorax, the head being distinct from the thorax; a long segmented abdomen; subchelate cheliceres; pediform pedipalps, like an extra pair of legs, making five pairs in all; two eyes; the body hairy; and tracheal respiration.
