Note A, [p. 75.]—The mandibles or external jaws of spiders are shown in [Fig. 39], and described in the text; the poison gland is shown at [Fig. 40]. The outlet for the poison may be seen at the tip of the fangs in [Fig. 39.]
Note A, [p. 84.]—Certain species, especially Orbweavers ([Fig. 86]) and Lineweavers, swathe their prey when captured and before eaten. (See [Fig. 33], [p. 69]; [Fig. 134], [p. 318].)
Note B, [p. 88.]—The bridge-lines here described are common objects in Nature. Spiders move freely from point to point, thereby often crossing considerable intervals. [Fig. 44] shows the way in which these bridges and webs may block a path.
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.
Note A, [p. 115.]—Dolomedes fimbriatus, a rather common English spider, makes or utilizes a rude raft of leaves, and drifts over the fens thereon. The American Dolomedes frequents the water but has not been observed to act as above.
Note B, [p. 117.]—As a rule spiders prey upon one another, without regard to species or sex. [Fig. 55] represents two males fighting.
