May. 9. Mating was not observed. On May 29 (early A. M.), 
or about twenty days after reaching maturity, the first cocoon 
of eggs was found suspended in the nest ; and the second very 
early in the morning of June to. Early in the morning of 
June 21 the third mass was deposited and the fourth about the 
same time July 4. The four cocoons were then suspended in 
the nest above the center in one corner, the first above and the 
other three in a nearly straight line below it, all taken together 
forming a triangle of which the second made the middle of the 
base directly below the first, the triangle’s apex. .The fifth 
mass was deposited during the night of July 30-31, and the 
sixth August 26-27. The female disappeared on September 6, 
1912. All of these eggs were fertile. 
Nos. 4 and 5, 6 and 7, 8 and 9, 15 and 16, and 18 and 19 
(in the table) were from the same nest, each couple being the 
second and third bags from the respective females, the first 
having hatched; No. 11 was the fourth mass from a nest, the 
three others having hatched; the other numbers were first or 
second masses. 
The number of eggs which may be laid by some spiders is 
illustrated by the contents of a medium-sized, hemispherical 
egg mass, covered with a silk cap found placed flat against a 
board at Paris, Texas, in March, 1904. It contained two thou- 
sand one hundred and three compact, round, yellow eggs, 
Unfortunately the species was unknown.
