Plate 19, fig. 9. 
Caudal region of head strongly elevated as usual, the tubercle 
rounded; posterior declivity of cephalothorax steep. Abdomen 
large and very high, its surface clothed with numerous very short, 
straight and acutely pointed hairs as is also that of the carapace. 
Carapace and legs dusky red-brown, the latter obscurely annulate. 
Sternum dusky brown, the coxae of legs beneath paler. Abdomen 
above brownish grey, with vague chevron-lines caudad, the anterior 
face and sides dusky with on the anterior face a small median white 
spot, the dark of the sides in part in oblique stripes more vaguely 
extending upon the dorsum; venter dusky or blackish mesally, paler 
laterally. 
Posterior row of eyes strongly recurved; median eyes one and three 
fifths their diameter apart, four times their diameter, or somewhat 
more, from the laterals. Lateral eyes at clypeal corners as usual, con- 
tiguous. Anterior row of eyes conspicuously procurved in the typical 
manner, the median eyes equal in size to the posterior medians, one and 
two fifths their diameter apart, twice their diameter from lower edge 
of clypeus, the latter narrower than eye area. Area of median eyes 
wider than long (9:7); wider behind than in front in the ratio 9:8. 
Lower margin of furrow of chelicera with three teeth of which the 
most proximal is largest; upper margin with four teeth. 
Spines of legs few, long. 
Epigynum small, of form, (Plate 19, fig. 10).
