her volume, and evidently she had not deposited all the ova within 

 her since her abdomen was still quite distended. At 1.53§ she com- 

 menced spinning the covering, with high strokes of the spinnerets 

 laying down threads that were looped, since a second attachment 

 of the spinnerets would be close to a first; but she placed very 

 few of these over the egg mass, spinning mostly upon the margin 

 of the cocoon base and even upon the foundation beyond it. She 

 spun very slowly, occupied most of the time in pauses, and occasion- 

 ally walked about the cage. At 2.23, when the egg was only imper- 

 fecth' covered with a thin silk layer, she loosened Avith her chelicera 

 about a quarter of the edge of the base from its moorings. She rested, 

 and at 2.27 seized the covering of the egg mass, pulled it, then rested, 

 holding it in her jaws. From 2.35 to 2.37 she spun again upon the 

 margin of the base, then turned about, seized the egg mass with her 

 jaws, began to eat the eggs, and devoured them all by 3.10. Finally, 

 with her chelicera she tore the base completely loose, and ate up that 

 too. 



Though this cocooning was a miscarriage, due to faulty oviposition 

 and to insufficient covering to the eggs, yet the method followed 

 would indicate that this species normally cocoons like others of the 

 genus.

 196, 194. No copulation occurred in any case before or after cocoon- 

 ing, and all the females except two were pregnant when captured. 



The following observations point to a simple courtship on the part of 

 the male, who is more brightly colored and considerably smaller than 

 the female:
