higher tlian) the centres of the latter; clypeus very sliglitly 

 or scareely longer than an anterior lateral eye's diameter; 

 posterior row of eyes strongly procurved, a line joining the 

 hind margins of the laterals passing sliglitly in front of the 

 centres of the medians; the median eyes ovate, larger than 

 the laterals and distant about tlieir own length from the 

 latter and nearly half their own length from one another; 

 median eye-area longer than wide, broadest in front ; lateral 

 eyes on each side subequal and between ^— | of a diameter 

 apart ; width of the posterior row of eyes slightly more than 

 half the width of the head at the same place, the posterior 

 row also about half a lateral eye's diameter wider on each 

 side than the anterior row. 



Chelicera with 1 weak inferior and 3 superior teeth, only 

 the middle one being large. 



Legs robust; all the tarsi and the two anterior pairs of 

 metatarsi scoj)ulate to the base, the posterior scopulte divided 

 by a broad band of sette ; two posterior pairs of metatarsi 

 with a distal scopular band on the side ; tibia I with an inner 

 row of 2 spines below ; metatarsus I with a pair of basal 

 spines. 



Fediioalps. — Tibia(Pl. XIII. fig. 20) measured along upper 

 inner edge subequal to the patella in length, its outer side 

 produced at apex into a long, stout, curved process, which is 

 closely appressed to the tarsus along its whole length with the 

 exception of the apex ; this process very broad at base, then 

 suddenly narrowed, the narrow portion long, straight, slightly 

 constricted above and below near apex and ending in a black 

 curved claw. Tarsus large, broadly ovate, acuminate, its 

 length equal to that of the tibia (inclusive of the process), its 

 inner margin with wide shallow sinus. Palpal organ very 

 large and compact, occupying the whole width of the under- 

 side of the tarsus excepting at the apex, its lower surface 

 divided longitudinally by a dark ridge and provided at the 

 apex with two short processes. 



? $ . — Legs more densely scopulate, the first tibia with a 

 short, internal, distal scopula (almost obsolete in the ^ ). 



Vulva consisting of a dark, convex, hairy, nearly rotund 

 plate (slightly longer than wide), divided longitudinally by a 

 deep groove, which is bordered on each side by a low, smooth, 

 black ridge, the ridges united anteriorly in front by a trans- 

 verse bridge spanning the anterior end of the groove and 

 ending separately behind in a rounded black convexity; the 

 edge of the bridge (which is visible only when dry, as in 

 PL XIII. fig. 20 a) is situated on a level with the anterior 

 edge of the rotund plate, and beneath it the groove is cou-
