 stout and prominent ; arranged as follows : two betvi'een the mesal lobes, one 

 between the mesal and second pair, one between second and third pair, one 

 between third and fourth pair — also a slender spine or hair. Seven very stout 

 spines between the fourth pair and the last abdominal segment preceding the 

 pygidium, two on this last segment. Tubular spinnerets numerous and dis- 

 tributed over nearly the whole surface of the p}'gidium.
