 cephalothorax, 1.9. 

 Legs, 4312; the third and fourth considerably longer 

 than the first and second. The first and second

The clypeus is one-fourth as high as the middle eyes. 

 The falces are vertical, longer than the face, and moderately

 occupies one-half of the cephalothorax. The first row of eyes
