 Cephalothorax with median process prominent; chelicerae with tubercle of 

 movable finger moderately high convex, teeth of fixed finger rather small ; 

 palps (fig. 17) with femur increasing slightly in breadth from near base to 

 near extremity, towards middle slightly concave behind and with corresponding 

 slight convexity in front, tibia distinctly but not greatly broader than distal 

 part of femur, membranous opening about i fi'ont maigin (stalk excluded), 

 hand rather long and broad (in 5 distinctly voluminous), fingers longer than 

 hand, teeth of fixed finger abniptly pointed uniform (without larger ones at
