 the second. Quadrilateral of the posterior eyes broader than long. 

 Length of the dorsal eye area to the cephalothorax as 1 : 6, 



Form. — Cephalothorax in front truncated and not one-half its great- 

 est transverse diameter, highest at the median groove, the posterior 

 declivity making an angle of 45° with the dorsal contour. Sides of the 

 head low and rounded, with long scattered hairs in the cephalic region. 

 Chelicera with 3 pairs of teeth, nearly straight in front in the o" , but 

 more arched and robust in the 9 , their length about twice the height 

 of the head in front. Labium longer than wide, apically truncated,
