shortest side is before; the posterior eyes of the trapezoid are 
the largest, and the anterior ones are much the smallest of the 
eight. The cephalothorax is slightly compressed before, trun- 
cated in front, rounded on the sides, convex, glossy, with a slight 
indentation in the medial line; it is of a brown colour tinged 
with red, and has an irregular dark-brown band on each side, 
and a spot of the same hue behind the medial indentation ; the 
space comprised between the posterior eyes of the trapezoid and 
those of the transverse curved row, and a spot on each exterior 
angle of the frontal margin, are of a dark-brown colour; the 
lateral margins and the front are provided with yellowish-white 
hairs, and some of a pale-red hue occur on the abruptly sloped 
base. The falces are powerful, subconical, vertical, supplied 
with dull-yellowish hairs in front, and armed with one or two 
minute teeth on the imner surface; 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 clothed with short yellowish- 
white hairs intermixed with long ones of a darker hue. These 
parts are of a brown colour tinged with red. The legs are 
slender, provided with hairs and long spines, and are of a pale- 
brown hue, with a few annuli of a deeper shade; the first pair 
is the longest, then the second, 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, which are without annuli, resemble the 
legs in colour, and have a curved, pectinated claw at their 
extremity.
