from the base of the posterior slope to the hindmost row of 

 eyes, behind which it is widest. On each lateral slope there are 

 a few dark-brown triangular flecks. Falces and sternum 

 pale-brown ; legs, palpi, and spinners brownish-yellow, flecked 

 with brown ; abdomen dark-brown above, with a narrow median 

 band of pale-yellow extending from tbe base to a point about a 

 third of the length of the abdomen from the spinners, and on 

 each side of this band runs, from the base to the spinners, a line 

 of rather indistinct dark flecks. Tbe colouration and markings 

 are similar in the female, but of a lighter shade. 



Cephalothorax about 1 mm. longer than broad at its broadest 

 part, somewhat longer than the patella and tibia of a leg of the 

 fourth pair, about twice as broad at the third pair of legs as at 

 the caput, rounded at the sides ; posterior slope very and lateral 

 slope moderately steep, not convex above ; ocular area very 

 hairy, and slightly sloping forward from the posterior to the 

 central pair of eyes. 



Front row of eyes curved backwards and shorter than the 

 middle row, which is shorter tban the posterior row ; eyes of 

 anterior row very small, and about equally distant from one 

 another ; those of the posterior row smaller than those of the 

 middle row. 



Falces slightly convex near the base, only slightly diverging 

 towards the extremities, groove toothed on each side : on the 

 under-side 3 teeth, 2 large and 1 small, and on the upper side 

 1 large tooth, with a very minute one on each side of it ; claw 

 short and slender. 



Ma.nlla. slightly inclined to the lip, small at the base and 

 gradually becoming larger towards the extremities ; rounded in 

 front on the outer side, and having a dense fringe of fine hah 

 on the inner side. 



Lip only slightly convex, more than half as long as the 

 maxillae ; constricted at the base, broadest near the middle, and 

 slightly rounded in front. 



Sternum ovate-cordate, with a median groove extending from 

 the anterior to the posterior margin. 



Abdomen ovate, about as long as and slightly narrower than 

 the cephalothorax, densely hairy ; spinners somewhat divergent, 

 inferior pair longer and stouter than the superior pair; auua 

 prominent. 



Leijs 4, 1, 2, 3 ; no spines on the tarsi, nor on the under-side 

 of the femora and patellae. The patella} of the first and second 

 pairs are witbout spines, but those of tlic third and fourth pairs 

 have one or two slender spines on the superior surface. The 

 femora of all the legs are bpiuous above, and the tibi© and 

 metatarsi above and below. 



Palpi armed with spines above only ; humeral joint thickest 

 at the foro extremity, bent outwards and laterally compressed ;
