Palp. On the inner (anterior) surface of the tibia are two long but rather 
weak spines and many of the bristles forming the tuft on the ventral surface 
I of this segment are spiniform. 
Sternum. The second pair of sigilla is not deeply sunk in depressions. 
Carapace about as long as the metatarsus and three-fifths of the tarsus of 
the fourth leg, and a trifle longer than the combined metatarsus and tarsus of 
the first leg. The deep part of the fovea is slightly procurved. The lateral 
margins of the carapace are fringed with bristles which are most numerous in 
the posterior half. The surfaces are for the most part devoid of setae but some 
occur in the posterior half, a few occur on the mid-line between the fovea and 
the ocular tubercle, others along lines radiating from the fovea and some fine 
hairs occur on the lateral portions of the head region.

Colour. Carapace dark brown, chelicerae and femora of legs and palps 
blackish brown; the remaining segments of the legs and palps are reddish 
brown except the tarsi and metatarsi which are a little darker, those of the 
first two pairs of legs being about the same tint as the carapace. Upper surface 
of abdomen dull yellowish with infuscations which are somewhat indefinitely 
shown, being obscured by the black bristly hairs which cover the surface: in
