 white and orange lanceolate hair, and brown bristles behind the 

 front row of eyes; the mandibles, lip, and maxillte yellow-brown;, 

 sternum and coxaj brighter yellow- brown, with pale brown up-

 patellar, and tibial joints, paler on the metatarsal and tarsal, 

 sparsely furnished with fine unstaiiding brown bristly hair and 

 grey claw-tufts. The palpi yellow-brown on the femoral and 

 under side of the patella and tibial, but on the ujiper side of these

 brown. 



The abdomen above is mottled with small yellow and brown 

 .spots, with a patch of brown bristly hair at the base ; behind this

 way down each side of the abdomen. On the lower half of the 

 back is another smaller similar fillet of white hair. The under- 

 side is smooth yellow-grey with minute brown simple hairs ; 

 spinnerets brown. 



The cephalic part of the cephalothorax slopes downward from 

 the rear row of eyes to the front and from about the saijie point 

 to the rear, the thoracic part being in length as eight to five 

 of the cephalic. The surface is smooth and shiny. The eye 

 quadrangle is one-third wider than long. The eyes of the rear 

 row are very convex and as large as the front laterals, slightly 

 narrower than the front row. The small second row eyes are 

 situated midway betv.-een the rear and front laterals. The eyes 

 of the front row are slightly recurved, the laterals half the 

 diameter of the median, and the clypeus half the width of the 

 latter. A short thoracic fovea lies just behind the rear row of 

 eyes. 



The mandibles are conical, sti-aight, and perpendicidar, with 

 rather long fangs. 



On the inner margin of tiie falx-sheath is a bifurcated tooth, 

 with two single ones on the outer margin. 



The lip is longer than broad, rounded anteriorly, and more 

 than half the length of the maxillae, which are upright, straight 

 at the anterior end, rounded on the outside of their upper end,, 

 and tapering to the base.
