Length of the female (not including the spinners) + of an 
inch ; length of the cephalothorax ~3,, breadth 4; breadth of the 
abdomen +; length of a leg of the third pair z+; length of a 
leg of the second pair +. 
The cephalothorax is somewhat quadrate, but rounded on the 
sides; it is convex and glossy, but slopes abruptly at the base, 
and gradually to the front, which projects a little beyond the 
mandibles; it has a small indentation near the middle, and is 
provided with a few scattered black hairs, eight, longer than the 
rest and closely grouped, having the appearance of a slightly 
curved horn, situated near the minute intermediate eye of each 
lateral row on its outer side; the falces are short, subconical, 
and vertical ; the maxille are straight, and enlarged and rounded 
at the extremity; the lip and sternum are oval, the latter being 
broader at its posterior than at its anterior extremity; the legs 
are robust, particularly those of the first and second pairs, and 
are ‘provided with hairs and spines, two parallel rows of the 
latter occurring on the inferior surface of the tibiz and meta- 
tarsi of the first and second pairs; the third pair is the longest, 
then the fourth, and the second pair is the shortest ; each tarsus 
is terminated by two curved, slightly pectinated claws, below 
which there is a small scopula; the palpi are slender, and are 
supplied with numerous whitish hairs, especially on the digital 
joint. These parts are of a yellowish-brown colour, the sternum 
and palpi being the palest. The eyes are nearly encircled by 
short, coarse, white hairs; the lateral eyes are seated on tuber- 
cles placed on dark reddish-brown patches, the minute one of 
each row being nearer to the anterior than to the posterior eye 
of the same row. The abdomen is oviform, pointed at the spin- 
ners (which are prominent), densely clothed with hairs, mode- 
rately convex above, and projects over the base of the cephalo- 
thorax; the upper part is of a brownish-yellow colour tinged 
with red on its margins, the posterior margin forming a curve 
above the spinners whose convexity is directed forwards ; a line 
composed of minute black spots borders each lateral margin of 
the upper part, and a band of the same hue, which is supplied 
with white hairs having a silvery lustre, extends along the mid- 
dle ; this band increases in breadth to its extremity, which is 
crescent-shaped ; the sides and under part have a pale dull- 
yellow hue; the former are clothed with white hairs, and have 
a broad, irregular, brownish-black band extending along each, 
whose continuity is interrupted at its posterior extremity; a
