Length of the male ;5,ths of an inch; length of the cephalo- 
thorax +; breadth }; breadth of the abdomen 3; length of an 
anterior leg %; length of a leg of the third pair 55,. 
The cephalothorax is convex, slightly compressed before, 
rounded on the sides and in front, without an indentation in 
the medial line, and is of a very dark-brown colour, faintly 
tinged with red. The eyes, which are nearly equal in size and 
diaphanous, are closely grouped in the form of a small oval open 
in front, on a prominence of the cephalothorax, situated imme- 
diately above the frontal margin, the two anterior ones being 
rather the largest of the six. The falces are subconical, promi- 
nent, armed with a few small teeth, and fringed with long hairs 
on the inner surface; the maxille are straight, enlarged and 
convex at the base, and somewhat pointed at the extremity, 
which is rather protuberant on the inner side; the lip has an 
oblong-oval form, decreasing in breadth to the apex, which is 
notched, and has a transverse furrow at its base; and the ster- 
num is oval. These parts are of a red-brown colour, the sternum 
being the darkest, and the maxille and apex of the lip the 
palest. The legs are moderately long, provided with short hairs, 
and have a red hue; the third and fourth pairs are rather the 
palest, and have a few sessile spines on the tibia, metatarsus, 
and tarsus ; the first pair is the longest, then the second, and 
the third pair is the shortest ; each tarsus is terminated by two 
curved, minutely pectinated claws, and below them there is a 
small scopula. The palpi resemble the legs in colour; the 
digital joint is small, oval, convex and hairy externally, slightly 
concave underneath, and with this concavity the palpal organs 
are connected by a short pedicle; they are prominent, directed 
upwards, not very complex in structure, oviform at the base, 
from which a long, curved, somewhat depressed process extends, 
whose extremity appears to be bifid, but its dark-brown divergent 
branches are connected by pale delicate membrane ; these organs, 
which have a small, slightly curved, dark-brown process near 
their middle, on the under side, are of a pale-yellowish-red hue, 
with two transverse brownish-red bands at their oviform base, 
formed apparently by the convolutions of an internal vessel. 
The abdomen is oviform, thinly clothed with short hairs, convex 
above, and projects a little over the base of the cephalothorax ; 
it is of a very pale-yellow colour, reticulated with brown on the 
upper part, a short longitudinal line of the latter hue occurring
