Observations. This spider is usually found under logs in the 

 woods. It is strongly characterized, and cannot be taken for 

 any other. The hairs or bristles on the knobs of the legs are 

 laid close on the leg, and are not visible to the naked eye on 

 that account ; they are probably susceptible of voluntary mo- 

 tion, for defence.
