 usually made under some large leaves, is white, orbicular. The 

 mother hatches her progeny, and continues with the young for 

 some time after they are come out ; the young living together 

 under a common tent. A specimen was found in December, 

 the cephalothorax of which was wider, the lower row of eyes 

 straight, the abdomen small and tapering, with only a few 

 abbreviated lines. Was this a distinct species ? A male was 

 found, Alabama, April, measuring over three inches from the 

 end of one of the second pair of legs to the end of the other.
