66 ARANEIDEA, 
evening this remarkably handsome spider was observed running away on the ground. 
Two Indians who took it up successively as quickly dropped it on receiving sharp 
bites; it was most active and pugnacious, but was finally secured by Mr. Reutter. The 
bitten men complained of severe itching for hours afterwards,” 
The colour of the abdomen is described by Mr. Sarg as ‘‘deep red-orange furred 
with hairs of cadmium-yellow,” and the underside “a shade of chocolate and purple 
madder.” These richer colours therefore have now subsided into the plainer ones 
described above from the preserved specimen. 
Sadala fugiens, sp. n. 
Adult male, length 6 lines. 
The cephalothorax is a little longer than broad ; caput broad, slightly curvo-truncate anteriorly, the lateral mar- 
ginal compression rather strong; profile curvo-convex ; colour dull orange-yellow, the caput, especially 
its sides along the junction with the thorax, strongly suffused with brown; the other normal indentations 
are also marked with dusky brown. ‘The height of the clypeus is rather less than the diameter of one of 
the fore central eyes. 
The eyes are in two as nearly as possible straight lines, though if looked at in some positions the lines might 
be described as slightly curved, the convexity of the curves directed backwards, and the anterior row 
more curved than the posterior. The two central eyes of the anterior row are scarcely, if at all, larger 
than the laterals; those of the posterior row are smallest, and of equal size. The interval between the 
hind central pair is distinctly less than that between each and the lateral next to it. The eyes of the 
anterior row are equidistant from each other. The four central eyes form a square whose anterior side is 
rather the shortest. 
The legs are long, moderately strong, 2, 1, 4, 3. Their colour is orange-red-brown, the tarsi and metatarsi of 
a deeper hue, and furnished with a broad scopula and claw-tuft. Spines moderately long and strong. 
The palpi are of moderate length; the cubital joint is short, but a little longer than broad; the radial joint 
is just double the length of the cubital, slightly enlarging towards the fore extremity, which ends on the 
outer side with a small tapering, not very sharp-pointed apophysis, no longer than the width of the 
hinder extremity of the joint. The digital joint is long, narrow-oval, longer than the radial and 
cubital joints together, and of a dark brown hue, thickly clothed with hairs, the rest of the palpus being 
similar in colour to the legs. Palpal organs simple. 
The falces are powerful, straight, not very convex in profile, of a deep rich red-brown colour, clothed with coarse 
pale hairs and bristles. 
The mawzle are strong, straight, enlarged and rounded at the extremity, slightly inclined to the labium, of 
the same colour as the falces, and furnished with a tuft of coarse reddish hairs at the extremity on the 
inner side. 
The Jabiwm is nearly square, rather rounded at the apex, and about the length of the maxille, which it 
resembles in colour. 
The sternum is heart-shaped, pale yellow, similar in colour to the basal joints of the legs. 
The abdomen is oval, broadest in front, of a yellow-brown colour, clothed with pale hairs. The normal marking 
on the fore half of the upperside (corresponding to the dorsal vessel) is indicated by dark brownish broken 
marks and lines, followed on the hinder half by an indistinct longitudinal series of reddish-brown united 
angular markings or chevrons, which reach to the spinners ; these are short and compact, and from them 
to the spiracular plates extends a broad deep blackish-brown central band which widens as it runs 
forwards, and becomes of an elongate lyre-shape. The sides are marked with oblique dark irregular 
lines.
