CHAPTER X.

=Note A, p. 97.=--The egg-bag within which the mother spider places her eggs is popularly, though not quite correctly, called a cocoon. It is sometimes simply a wad or ball of loose silk, but more frequently is a bag of stiff and closely woven silk as at Fig. 22. Fig. 47 is the cocoon of an Orbweaver, Nephila plumipes; Fig. 48, of a Saltigrade or Jumping Spider, Phidippus opifex MCCOOK.
