spiders are divided into two principal groups: the dipneumona, having two lungs: and the Tetrapneumona, having four lungs. See mygale. The former group includes several tribes; as, the jumping spiders (see saltigradae), the wolf spiders, or Citigradae (see under Wolf), the crab spiders, or Laterigradae (see under Crab), the garden, or geometric, spiders, or Orbitellae (see under geometrical, and Garden), and others.
