 $ . Total length, 4.3 mm. 



Cephalothorax : Length, 2 mm.; width, 1.1 mm. 

 Legs, 4312 ; slender, excepting the femur of the 

 first, which is greatlj^ thickened, being as wide 

 as long. 



Cephalothorax moderately high, short and compact ; 

 cephalic part inclined forward, on a slightly higher plane than 

 thoracic. There is a slight drop behind the dorsal eyes, back 

 of which the thoracic part is level for a short distance and then 

 falls steeply. The clypeus slants backward from the anterior 

 eyes. The quadrangle of the eyes is but little wider than long, 

 is wider in fi-ont than behind, and occupies about half of the 

 cephalothorax. The anterior eyes are close together, the 

 middle being about twice as large as the lateral ; they form a 

 slightly curved row. The second row of eyes is half-way be- 

 tween the first and third rows. The dorsal eyes are as large 

 as the lateral, and form a row which is nearly as wide as the 

 cephalothorax at that place. The falces are weak and short, 

 but strongly inclined — almost horizontal ; they are not visible 

 from above. The lip is a little longer than wide ; the maxillee 

 are long ; the sternum is wide and somewhat heart-shaped. 

 The femur of the first leg is enlarged all out of proportion to
