wards hind margin, also an inner lateral series of minute irregular 

 granules ; hind margin bearing in the centre two slightly divergent, 

 short, acute spines, and on either side a long, robust, slightly de- 

 pressed, curved spine directed backwards over the coxae of hind legs, 

 and having a minute tubercle on its inferior surface near the base ; a 

 second, robust, short, incurved spine on the postero-inferior edge of 

 the coxal sheath; abdominal segments margined with tubercles; 

 legs rather long, femora of first three pairs minutely denticulate along 

 their antero-inferior margin ; third pair with three prominent denti- 

 cles, tibial second joint also denticulate on its postero-inferior margin ; 

 hind legs with cox^ obtusely trispinose and denticulate; femora 

 densely spinose ; three curved spines on the interior surface of its 

 proximal end prominent ; tibiae densely spinose, the spines on inferior 

 surface very prominent, increasing in length towards the proximal 

 end, which terminates internally in four short radiating spines ; tarsi 

 densely denticulate ; palpi subcylindrical, with short slender spines ; 

 cheliceres smooth, cylindrical ; pincers serrated internally ; ventral 

 surface of legs and cephalothorax minutely granulose. 



Length of cephalothorax 3i lines, of entire body (including closed che- 

 liceres) 5 lines ; relative length of legs 1, 3, 2, 4, the fourth pair being 

 the longest.

This species may at once be distinguished from all its allies by 

 the densely spinose character of the hind pair of legs.

Colours : pitchy ; the oculiferous tubercle, the coxae of the first three 

 pairs of legs, and the edges of abdominal segments yellow. 



Male. Above, oculiferous tubercle scarcely prominent, with two central 

 granules ; prothoracic area transversely oblongo-ovate ; central area 

 subrotundate, smooth, separated into four divisions by the sutures ; 

 extreme edge of the margin minutely granulose ; hind margin termi- 

 nating on each side in a robust, oblique, slightly depressed spine ; 

 abdominal segments minutely granulose ; three front pairs of legs 

 nearly smooth, excepting the tibiae of the third pair, which are strongly 

 dentate externally ; hind legs with coxae coarsely trispinose on their 

 external lateral margins j femora rugose, with four increasing denti- 

 cles on their external inferior margin at the proximal end; tibiae 

 densely tuberculate and dentate-pectinate on both lateral margins ; 

 palpi subcylindrical, rather rugose, with short slender spines ; cheli- 

 ceres subcylindrical, pilose ; ventral surface of cephalothorax coarsely 

 rugose. 



Length of cephalothorax 2^ hues, of entire body 3 lines ; relative length 

 of legs I, 3, 2, 4, the fourth pair being the longest.
