Length of the female, gth of an inch ; length of the cephalo-thorax, ~th, breadth, T ~tli; 
breadth of the abdomen, T ' 5 th; length of a posterior leg, jth ; length of a leg of the second 
pair, jth. 
The legs are robust, hairy, and of a yellowish-brown colour ; the fourth pair is the 
longest, then the third, and the second pair is the shortest; on the under side of the tibiae and 
metatarsi there are some sessile spines, those on the first and second pairs being the most 
conspicuous ; and each tarsus is terminated by two slender, curved, plain claws. The palpi, 
wdiich resemble the legs in colour, have a short, dark, longitudinal streak on the anterior part 
of the radial joint. The cephalo-thorax is nearly quadrilateral; it slopes abruptly behind, 
projects a little beyond the falces, in front, and is clothed with hairs, which are densest on the 
anterior part; its colour is yellowish-brown, the region of the eyes and the' lateral margins 
being blackish, and the eyes are encircled by red hairs. The falces are small, conical, vertical, 
armed with a few teeth on the inner surface, and, with the maxillae, are of a yellowish-brown 
colour, tinged with red. The lip is triangular, pointed at the apex, and of a brown hue, with 
yellowish-brown margins; and the sternum, which is oval, is provided with long, dark- 
coloured hairs, and has a yellowish-brown tint. The abdomen is oviform, hairy, rather 
depressed, and projects over the base of the cephalo-thorax; it is of a yellowish-brown colour, 
with numerous, irregular, black streaks on the sides and upper part; a series of black marks, 
somewhat of a triangular form, occupies the medial line, and two longitudinal rows of black 
spots extend along the under part. The sexual organs have a reddish tint, with two small, 
circular spots of a darker hue; and the colour of the branchial opercula is pale-brown, tinged 
with yellow. 
The male is smaller and darker coloured than the female. Its cephalo-thorax has a brown 
hue, the lateral margins being almost black, and is clothed with orange-brown hairs, which 
are densest on the anterior part. The falces are of a dark-brown colour, with red-brown ex¬ 
tremities ; and the maxillse, sternum, and lip have a brown hue, the last being the darkest. 
The anterior legs are powerful and black, with the exception of the tarsi, which are white, and 
in longitudinal extent are equal to the third pair; the third and fourth pairs have a reddish- 
brown hue, and the colour of the second pair is the same, except that the under part of the fe¬ 
mora, tibiae, and metatarsi, is black, and the tarsi have a yellowish-white tint. The humeral joint 
of the palpi is clavate, and of a brownish-black hue, with some strong bristles at its extremity; 
the cubital and radial joints are short, and of a pale, yellowish-brown colour, the latter having a
