Cephalothorax moderately high and steep sided, relatively wide in 

 front. In profile line of dorsum highest behind third eye row, con- 

 cavated at front of dorsal furrow. Face low, in height hardly half the 

 length of the chelicerae. Face at base about wide as length of cheli- 

 cerse, sides more than usually widely slanting, more convex below. 



Anterior row of eyes a little shorter than the second, procurved; 

 anterior median about their radius apart, twice as large in diameter as 

 the lateral eyes; anterior lateral eyes nearly their diameter from the 

 front margin of the elypeus, more than their diameter from eyes of 

 second row; anterior median eyes less than half their diameter from 

 eyes of second row and nearly as close to front margin of elypeus ; eyes 

 of second row scarcely more than half their diameter apart, two-thirds 

 their diameter from eyes of third row which are two-thirds or a little 

 more as large; eyes of third row twice as far from each other as from 

 eyes of second row. Cephalothorax 5.5 times as long as the quad- 

 rangle of posterior eyes. 



Legs short, the fourth pair less than three times the length of the 

 cephalothorax; tibia -f- patella IV shorter than the cephalothorax; 

 metatarsus IV shorter than tibia + patella ; tarsi and metatarsi I and 

 II scopulate, the scopulse not dense; tarsi III and IV with very thin 

 scopulse at sides, the ventral surface mostly occupied by a broad band 

 of long setse; tibia + metatarsus I and II armed as usual beneath; 

 patella I and II unarmed.

Male. — Cephalothorax relatively narrower in front than in female 

 and more depressed. Patella I and II unarmed. Tibia + patella IV 

 shorter than cephalothorax.
