by twice their diameter; eyes subeqiial in size and nearly equidistant, 

 being separated from each other by a space rather less than their 

 radius; anterior lateral eyes more than their diameter from the front 

 margin of clypeus, closer to the eyes of second row; eyes of second row 

 large, less than their diameter apart; eyes of third row two-thirds as 

 large as those of the second, nearly twice as far from each other as 

 from eyes of second row; cephalothorax five times as long as quad- 

 rangle of posterior eyes. Margins of furrow of the chelicera? armed 

 as usual, the third tooth of the lower margin a little reduced. Labium 

 much longer than wide (19 : 16); basal excavation one-third the total 

 length or rather longer; sides below straight and subparallel to 

 middle, then straight and converging to angles in front ; front margin 

 very gently convex laterally and indented at middle. Legs long and 

 slender; the posterior tarsi slender and nearly as long as tibia 4- 

 patella; all tarsi densely scopulate, the scopute clearly divided on 

 posterior pairs by a narrow median setose band, on the anterior pairs 

 the scopuke extend also upon the metatarsi entirely to the base and 

 even upon the tibia? distally.
