THE SPIDER RA VISHERS. 161 



ned in front she paid no attention until she was touched, when 

 she threw up her first legs in the way that is characteristic of 

 spiders, and snapped with her falces. When picked up she bit 

 the hand severely. She was evidently a good deal affected by 

 the poison and did not act like a normal spider. Voluntary 

 movement was not abolished but she had little initiative and 

 remained quiet unless disturbed. A little later in the day she 

 ran a few steps without being touched. 



On the nineteenth there was but little change. When the 

 tip of one of the legs was touched it was drawn up toward the 

 body, and by touching the first, second, and third in succession 

 they would all leave the ground, but when the fourth was stim- 

 ulated and drawn up one of the others came down so that she 

 always had one to support her. On August twentieth, when 

 placed on her back she was unable to turn over, although she 

 made a great effort to do so. On the twenty-second she ate a 

 fly, and on the twenty-third she caught an uninjured fly which 

 was put into her glass. From that time on she caught anything 

 that was put into her glass and seized with her falces any ob- 

 ject that was used to touch her. One day we gave her a large 

 stink-bug, one of the Pentatomidae. She at once caught it but 

 when it sent off its terrible odor she dropped it and drew back 

 in haste. The odor was so powerful that the spider fell over 

 on to one side throwing up all the legs on the side toward the 

 bug, in the most comical fashion. We now feel quitei confident 

 that stink-bugs are protected from spiders. 



Up to the thirteenth of November our captive changed but 

 little. She caught flies when they came in contact with her, 

 turning so quickly that they were seized before they could 

 escape, but when they walked in front of her she evidently did 

 not see them, being quite blind. She ran rapidly and had com- 

 mand of all her parts, and yet voluntary movement was not 

 quite normal. Perhaps her condition might be expressed by 

 saying that she was more sluggish than is usual in her species, 

 moving about in her glass much less than other specimens of 

 her kind have done when we have kept them in confinement.
