Length of the female, ^ths of an inch ; length of the cephalo-thorax, jth, breadth, T ' s tli ; 
breadth of the abdomen, | g ths; length of an anterior leg, 5 7 oths ; length of a leg of the third 
pair, 1th. 
The eyes are disposed on the anterior part of the cephalo-thorax in two transverse, 
curved rows, forming a crescent whose convexity is directed forwards; the eyes of each 
lateral pair, which are seated on a tubercle, are larger than the intermediate ones, those of 
the anterior row being the largest of the eight. The cephalo-thorax is large, convex, compressed 
before, rounded on the sides, broadly truncated in front, depressed anteriorly, still more 
abruptly so towards the base, and has a small indentation in the medial line; the sides are of 
a brown colour, marbled with yellowish-white, and on the posterior part of each there is an 
oval black patch, with its smaller extremity directed forwards, whose outer margin is broken 
by a yellowish-white spot; the lateral margins and a large band extending along the middle 
are of a yellowish-white colour, the latter, immediately behind the eyes, being tinged with 
brown and marked with spots and two short, parallel streaks of a deeper shade; a short, 
curved, black line occurs near each side, below the lateral eyes, and the frontal margin is 
fringed with a row of strong, black hairs directed forwards. The falces are short, powerful, 
subconical, vertical, and of a yellowish-white colour in front; the base, outer side, and 
extremity having a brownish-black hue. The maxillae are somewhat pointed at the extremity, 
and inclined towards the lip, which is triangular, but rounded at the apex; and the sternum 
is heart-shaped. These parts are of a pale, brownish-yellow colour, the base of the lip, that 
of the maxillae on the inner side, and minute spots on the sternum, having a dark-brown hue. 
The legs are provided with hairs and spines, tw r o longitudinal rows of the latter occurring on 
the inferior surface of the tibiae and metatarsi of the first and second pairs; they are of a 
brownish-yellowish colour, the tarsi having a tinge of red, and are marked with streaks, spots, 
and annuli, of a brownish-black hue ; the first and second pairs, which are longer and more 
robust than the third and fourth pairs, are equal in length, and the third pair is the shortest; 
each tarsus is terminated by two curved, pectinated claws; and the short palpi, which 
resemble the legs in colour, but are very slightly marked with brownish-black, have a curved, 
pectinated claw at their extremity. The abdomen is broader at the posterior than at the 
anterior extremity, sparingly clothed with hairs, convex above, and projects over the base of 
the cephalo-thorax ; the upper part is of a dull, reddish-brown colour, with obscure, slightly 
oblique lines of a paler hue, and is marked with seven minute, indented, yellowish-white spots, 
describing an elongated angle whose vertex is directed forwards; a short, fusiform line, of the 
same hue, extends along the middle from the spot forming the vertex of the angle, a little beyond 
the two spots constituting the second pair; the anterior extremity, sides, a space above the
