sack at the bottom of their hole, and, when the young 
hatch out, take them on their back and carry them 
about, as I have often seen them. I have, however, never 
discovered any such egg-sack, though I dug out many 
of their holes. It may be that I did not dig them up at 
the proper time to find their eggs. They are too filthy 
when confined, or I would send you a live one. 
Two or three species of Mygale carry a sack well filled 
with eggs, attached to the tip of their abdomen; and 
when the young ones hatch out, they take them on their 
backs and carry them like the Mygale Hentzii. There 
is one species of the family that constructs an exceedingly 
curious gossamer nest in a hole in the ground. It first 
digs the hole about six inches deep, and then lines it 
thickly to the bottom with a very fine white web, finishing 
it with a cunningly wrought and very neatly fitting trap- 
door, having hinges and a string to fasten it on the in- 
side. This type of spiders is very rare in Middle Texas.
