Length of the female, 4 an inch; length of the cephalo-thorax, 3 th, breadth, 1 th; 
breadth of the abdomen, jth; length of a posterior leg, Jths; length of a leg of the third 
pair, ^ths. 
The eyes are almost equal in size; the four intermediate ones form a square nearly, 
the anterior pair being rather the largest of the eight, and the eyes of each lateral pair are 
seated obliquely on a small tubercle, but are not contiguous. The cephalo-thorax is convex, 
hairy, compressed before, and rounded on the sides, which are marked with furrows 
converging towards an elongated indentation in the medial line; it is of a reddish-brown hue, 
with a broad, longitudinal band on each side, and lateral margins of a dark-brown colour; 
the reddish-brown spaces are usually covered with yellowish-brown hairs, and form a 
broad band extending along the middle, and another immediately above each lateral margin- 
The falces are powerful, conical, vertical, and armed with two rows of teeth on the inner 
surface; the maxillae are short, straight, and increase in breadth from the base to the 
extremity, which is rounded and fringed with long hairs on the inner side; the lip is 
somewhat quadrate, being rather broader at the base than at the extremity ; and the sternum 
is heart-shaped. These parts are of a reddish-brown colour, the maxillae being much 
the palest. The legs are robust, provided with hairs and spines, and are of a reddish-brown 
hue, the extremities being the darkest; a faint tinge of green occurs on the thighs, and 
the tibiae and tarsi are marked with a few dark-brown annuli; each tarsus is terminated 
by three claws ; the two superior ones are curved and pectinated, and the inferior one 
is inflected near its base, on each side of which there are two or three fine teeth. The palpi 
resemble the legs in colour, but are without annuli, and have a curved, pectinated claw 
at their extremity. The abdomen is oviform, hairy, convex above, projecting over the base of 
the cephalo-thorax; it is of a dark-brown tint on the upper part, with a series of fine, 
angular, yellowish-brown lines extending along the middle; their vertices, which are directed 
forwards, are obliterated at the anterior part of the series by a longitudinal band of a 
yellowish-brown hue, and immediately above the spinners there is a spot of the same 
colour; the sides are of a dark-brown hue, mottled with yellowish-brown, and the under part, 
which is of a yellowish-brown colour, has a broad, longitudinal, dark-brown band on each side, 
comprising a yellowish-brown line; the superior spinners are long, triarticulate, and of a dark, 
reddish-brown hue, with the spinning tubes distributed on the inferior surface of the terminal 
joint; the sexual organs present a red-brown orifice bisected by a longitudinal septum, and 
surrounded by a very dark, reddish-brown margin, which is most prominent at its posterior 
part; the colour of the branchial opercula is yellow. This species has numerous compound, 
sessile hairs on its body and limbs. 
The male is smaller and slenderer than the female, but it resembles her in colour. The 
palpi are short, and have a red-brown tint, with the exception of the digital joint, which is of 
a dark-brown hue, tinged with red, particularly at the extremity; the cubital and radial joints 
are short; the former projects a strong, brownish-black apophysis from its extremity, on the 
outer side, and the latter, which is rather the shorter, has at its extremity, on the under side, 
a longer and more pointed apophysis of a reddish-brown colour, which is protuberant at its 
base, and has a small process on the outer side; The digital joint is oval, pointed at the 
extremity, convex and hairy externally, concave within, comprising the palpal organs. These
