hairs intermixed, and a dark brown spot occurs on each exterior 
angle of the frontal margin. The falces are long, powerful, 
subconical, inclining to cuneiform, and vertical; the maxille 
are enlarged where the palpi are inserted, truncated at the ex- 
tremity on the outer side, and inclined towards the lip, beyond 
which they extend considerably ; the lip is long, somewhat tri- 
angular, and notched at the apex; the sternum is heart-shaped ; 
the legs are long, slender, and provided with hairs and long 
spines; the first pair is the longest, then the second, and the 
third pair is the shortest; the tarsi are terminated by three 
claws; the two superior ones are curved and pectinated, and 
the inferior one is inflected near its base; and the palpi, which 
are short, have a curved pectinated claw at their extremity. 
These parts are of a pale red-brown colour; the falces are the 
darkest, and the femur of each leg has two longitudinal brown 
lines on its inferior surface. The abdomen is long, slender, 
somewhat cylindrical, tapering to the spinners, and projects 
slightly over the base of the cephalothorax ; it is densely clothed 
with short hairs, and the upper part, which is of a yellow-brown 
colour, bordered laterally by a red-brown line, is marked with 
numerous pale yellow streaks and spots symmetrically arranged, 
and disposed on similar streaks and spots either of a dark brown 
or of a red-brown hue ; the colour of the under part is yellowish 
white ; a large black band extends along the middle, whose an- 
terior part comprises a short, longitudinal, yellowish-white 
streak ; the sexual organs are highly developed, nearly circular, 
and of a dark reddish-brown colour, that of the branchial oper- 
cula being yellowish brown.

Length of the female 4th of an inch; length of the cephalo- 
thorax +; breadth 4,; breadth of the abdomen %; length of a 
posterior leg 7; length of a leg of the third pair 5%. The ab- 
dominal spines are not included in the measurement. 
The cephalothorax is somewhat quadrate, the sides being 
slightly rounded ; the anterior part is thinly clothed with short 
hairs, abruptly elevated throughout its entire breadth, and has 
on its summit two glossy protuberances which are separated by 
a longitudinal furrow; and the posterior part is depressed, with 
a large indentation in the medial line; it is of a dark brown 
colour faintly tinged with red, the middle of the posterior part 
having a yellow-brown hue. The eyes are small, and situated 
immediately above the frontal margin; the four intermediate
