 advances by short runs, twitching 

 the front legs and abdomen every 

 few moments. 



Cyrba taeniola. — A small flat 

 spider, nearly black, the females 

 quarter of an inch long, and the 

 males a sixth of an inch (fig. 159).

 lateral 

 eyes half 

 as large 

 and a little separated from them. The 

 first legs are twice as thick as the others 

 and have the femora flattened, but in
