Mygale (Cteniza) antipodum. 



Chelicera deeper than long, ochrey-brown, the top at the base 

 somewhat hollowed, smooth ; sides smooth, front and tip with several 

 short hairs. 



Cephalothorax rotundo-ovate, pale ochrey-brown, the sides in front 

 somewhat grooved. Eyes situated on a slight elevation in front of 

 cephalothorax ! the two posterior eyes on each side close to each other. 



Legs of a pale brown, but deeper in colour than the cephalothorax. 



Abdomen of the same pale brown as the legs, covered with rather 

 long hairs ; the tail nearly as long as the abdomen, the terminal joint 

 elongate, slender, gradually thinner.

Mygale (Cteniza) hexops. 



Chehcera deep black, much deeper than long; above somewhat

Cephalothorax fulvous yellow, oval, somewhat truncated behind
