EPBIRIDiE. 
The cephalo-thorax is compressed before, broad in front, rounded on the sides, moderately 
convex, and has a large indentation in the medial line; it is of a brown-red colour, and is 
clothed with hoary hairs, which are densest on the lateral margins, and in the cephalic region. 
The falces are powerful, conical, vertical, and armed with teeth on the inner surface; the 
maxillse are straight, short, strong, and rounded at the extremity; the lip is semicircular, but 
slightly pointed at the apex; and the sternum, which is heart-shaped, and sparingly clothed 
with hoary hairs, has small prominences on the sides, opposite to the legs. These parts are 
of a very dark-brown colour, with the exception of the extremities of the maxillse and lip, 
which have a pale, reddish-brown hue. The legs are long, robust, provided with hairs and 
erect spines, and of a yellow-brown hue, with dark-brown annuli; the femora have a broad 
annulus at their extremity, that on each of the anterior ones extending nearly over half the 
joint; the tarsi are terminated by three claws of the usual structure, below which there are 
several smaller ones. The palpi resemble the legs in colour, and have a curved, pectinated 
claw at their extremity. The four intermediate eyes are seated on a prominence and nearly 
form a square, the two anterior ones, which are rather wider apart than the posterior ones, 
being the largest of the eight; the eyes of each lateral pair are placed obliquely on a small 
tubercle, but are not contiguous. The abdomen is oviform, thinly clothed with hairs, convex 
above, projecting over the base of the cephalo-thorax; the upper part is of a dull-yellow hue, 
a large, leaf-like, brownish-black mark, mottled with dull-yellow, whose lateral margins are 
sinuous, and which tapers to the spinners, extending along the middle ; the anterior part of 
this mark comprises a dull-yellow triangle, which includes a brownish-black one, both having 
their vertices directed forwards ; the posterior part of the mark comprises a dull-yellow cross, 
the longitudinal portion of which tapers towards the spinners, and includes a brownish-black 
line, which is broadest near its anterior extremity; the transverse portion of the cross is 
somewhat curved, and its extremities frequently break the continuity of the leaf-like mark, 
whose posterior part is crossed by several dull-yellow bars ; the sides have a dull-yellow hue, 
a broad, brown-black band, mottled with dull-yellow, and dentated at its superior margin, 
extending along each; the under part has a brown-black hue, with a curved, yellowish line 
on each side; the sexual organs have, in connexion with their posterior margin, a short, 
strong process directed forwards, on each side of which there is a small, glossy protuberance; 
their colour is dark-brown, tinged with red; and that of the branchial opercula is brown. 
The male, though smaller and slenderer than the female, resembles her in the design 
formed by the distribution of its colours. Its palpi are short; the cubital joint has at its 
extremity, in front, two long, curved bristles, directed forwards ; the radial is larger than the 
cubital joint, and projects a strong process from its outer side, which is gibbous near the 
base, and amply provided with long hairs ; the digital joint has a brown hue, and is some¬ 
what oval, having a curved process at its base directed outwards; it is convex and hairy 
externally, concave within, comprising the palpal organs, which are highly developed and 
complicated in structure ; near their base there is a long, slender, prominent, bifid process, 
with a small protuberance at its base, on the inner side; the superior division of this process, 
which is the stronger, is rounded at its extremity, and the inferior one terminates in a point; 
both are slightly curved towards the inner side; lower down a prominent, depressed, yellowish- 
brown process occurs, which is enlarged and rounded at its extremity, and near whose summit, 
on the inner side, the taper and finely pointed end of a strong process, curved round the
