and narrow, and the palpal organ large and complicated, with 

 a long fine tube that extends from the base along the outer 

 side and back to the hard appendages in the middle. The 

 epigynum (fig. 247) has a small, transverse, oval opening at 

 the hinder end, in front of which the coils of long tubes can be 

 seen through the skin. 



In New England Agalenidae PI. VII, fig. 2 is the epigynum

 abdomen. The outer or 

 upper pair are half as long 



as the abdomen, and the two joints are nearly of equal length. 

 The tracheal opening is in the middle of the abdomen, nearer 

 the epigynum than the spinnerets. The sternum is as wide as
