thin shell four eggs were distinctly visibleon May 27th; spiders’ 
legs became apparent within these eggs on July 1st; and between 
10th and 17th of that month I had the satisfaction of breeding 
thence four spotted-legged young spiders. Mr. Hirst informs 
me that the spider is Hro thoracica, Wid. Thereare similar sacs,
