Material. A good number of well preserved females, but 

 no male, have been examined. 



Head. The frontal sense-organ is rather slender, almost 

 two and a half times longer than broad; the rami with acute 

 apex. On each side only one lateral sense-organ which is pro- 

 portionately thick, on an average about two and a half times 

 longer than thick and with subacute or obtuse end. — The large 

 sternum has a posterior transverse, considerably recurved row 

 of five or six hairs (fig. 1 a\ close in advance thereof a hair 

 in the median line, and from this hair proceeds on each side 

 a row with two hairs outward and forward (often more forward 

 than in the figure) towards the base of the palpus. 



Chela. Each finger has nine slender spines, the distal one 

 somewhat thicker but not longer than the others; none of the 

 spines with any perceptible rudiment of a subapical incision. 



Palpi slender. The tibia is a little more than three times 

 longer than thick. The second metatarsal joint is about one 

 third longer than the first and slightly more than twice as long 

 as thick; the first tarsal joint is somewhat shorter than the se- 

 cond, the last joint somewhat shorter than the two preceding 

 joints together. 



I-egs slender. The first pair has the tibia nearly three 

 times longer than thick; the third metatarsal joint is about as 

 long as the fourth, and its stiff seta is inserted at the middle; 

 the last tarsal joint is five times longer than thick. — The last 

 pair of legs has the metatarsal joint a little longer than both 

 tarsal joints together, its sensory seta is inserted about at the 

 end of tlie first fourth of the joint and reaches almost to the 

 base of the tarsus; the first tarsal joint is one third shorter than' 

 the second. 



Abdomen. Ventral sacs are wanting. The fourth segment 

 on the ventral side with a median group of five or six robust 

 spine-like setîç set on a low protuberance close to each other
