thorax }; breadth ;1,; breadth of the abdomen +; ; length of 
an anterior leg 22; length of a leg of the third pair 3. 
The cephalothorax’ is somewhat compressed before, rounded 
on the sides, glossy, convex, particularly in the posterior region, 
with a slight indentation in the medial line, and some short, 
strong, black hairs on each side of its base; it 1s of a yellowish- 
red colour, a fine black line extending from each eye of the an- 
terior pair to the frontal margin, which has a dark brown spot 
on each exterior angle. The falces are powerful, subconical, 
and vertical; the maxille are long, obliquely truncated at the 
extremity, on the outer side, and slightly inclined towards the 
lip, which is broader towards the extremity than at the base, 
and truncated at the apex; the sternum is heart-shaped, and 
thinly clothed with short, light-coloured, and long, erect, brown- 
ish hairs; the legs are slender, and provided with hairs and 
long spines; the first pair is the longest, then the fourth, and 
the third pair is the shortest ; each tarsus is terminated by three 
claws ; the two superior ones are curved and pectinated, and the 
inferior one is inflected near its base; the palpi are short, and 
have a curved pectinated claw at their extremity. These parts 
have a dull yellowish hue; a black line extends along the infe- 
rior surface of the femoral joint of the legs, those on the femora 
of the posterior pair being the least conspicuous ; and a fine 
longitudinal line of the same hue occurs on each falx in front, 
which lines appear like a prolongation of those on the frontal 
margin. The eyes are seated on black spots on the anterior 
part of the cephalothorax; the four posterior ones form a 
strongly curved transverse row, whose convexity is directed 
backwards, each lateral eye being placed on a minute tubercle; 
the other four describe a trapezoid whose shortest side is be- 
fore; the posterior eyes of the trapezoid are the largest, and 
the anterior ones much the smallest of the eight. The abdomen 
is oviform, somewhat pointed at the spinners, convex above, 
and projects a little over the base of the cephalothorax ; it is of 
a yellowish-grey colour, finely reticulated with pale brown; a 
brown band extends along the middle of the upper part to the 
anus, having a minute point on each side, near its anterior ex- 
tremity, which is the darkest ; the sides are marked with oblique 
dark brown lines, more or less confluent, which are most con- 
spicuous on their posterior half; and a broad band of the same 
hue, having whitish scale-like hairs on each side of it, extends 
along the middle of the under part, and tapers to the spmners ; 
the posterior margin of the sexual organs, which are well deve- 
loped, is prominent, but obtuse, and their colour is brownish 
black, that of the branchial opercula being dull yellow.
