moderate; roundly truncated; frontal index more than half 

 lateral ; fovea subcircular, fairly deep ; radial and caput striae 

 well defined ; clypeus projects moderately, height visibly ex- 

 ceeds depth of eye-area ; profile-contour arched, posterior 

 slope very abrupt compared with anterior incline. 



Eyes large ; posterior row procurved ; middle pair on lake 

 spots, separated by about an eye's radius, removed by scarcely 

 their diameter from lateral pair ; anterior row recurved, cen- 

 trals dark, perceptibly smaller than hind pair — form a square 

 with them ; lateral eyes about one-fourth smaller than hind- 

 centrals, posited contiguously on prominent, lake - coloured 

 tubercles. 



Falces and cephalothorax concolorous ; linear, about twice 

 as long as broad, inclined perceptibly forwards. 



Maxillce pale stone-colour, dusky clouds ; linear, rounded, 

 basal third turgid ; slightly inclined towards each other. 



Labium similar in tone to maxillte, about one-third their 

 length ; oval. 



Sternum normal stone-grey shade ; cordate. 



Legs pale slaty-grey ; a slate-coloured, wide, vein-like 

 streak runs through their entire length ; almost glabrous ; few 

 black, bristle-like spines. 



Palpi pale metallic stone-colour ; humeral joint of some- 

 what even breadth, about one-fourth longer than two following 

 articles together ; armed with few spine-like bristles ; cubital 

 short, cup-shaped; radial joint large, crateriform, deeply cleft 

 above ; pars digitalis well developed ; basal fourth inserted 

 within the cup-shaped cavity of penultimate article ; lamina 

 sparingly haired, assumes a yellowish tone towards extremity ; 

 ovate curves round lower aspect of bulb ; prolonged in a stout, 

 trunk-like form, abscinded, apex concave ; genital bulb me- 

 tallic-grey ; membranous, convex above, deeply cleft at fore- 

 end ; the cutaneous fold of the superior (upper) extremity is 

 down-curved, somewhat revolute ; inferior projection about 

 same length as superior, wide, tapering, extremity rapidly 

 acute ; the brownish beading of fore-half, which is bent for- 

 wards, forms a continuous line with the bead bordering the 

 deeply sinuous membranous folds of the lower part of bulbus. 

 Within the bulb, just beneath the above-mentioned pro- 

 jections, are two dark, easily perceptible, subprocesses. 



Abdomen ovate in outline, sides deep; a depressedly conical 

 tubercle projects at the verge of the abrupt posterior slope. 

 Ground-colour yellowish-stone, sides have a dull metallic 

 lustre ; folium exhibits no very determinate limits ; spotted 

 with fair-sized, white, lobate flecks ; a V-shaped figure com- 

 posed of confluent flecks extends from apex of tubercle to 

 base of abdomen, enclosing an unspotted area, and bordering 

 the fuscous, linear petiole ; central third traversed by two lines
