Length of the female, ^ths of an inch; length of the cephalo-thorax, T 3 B ths,breadth, ith; 
breadth of the abdomen, |; length of an anterior leg, ^ths ; length of a leg of the third 
pair, ^ths. 
The four intermediate eyes form a square, and those of each lateral pair are seated on a 
tubercle, and are nearly contiguous. The cephalo-thorax is moderately convex, compressed 
before, truncated in front, rounded on the sides, and has a large indentation in the medial 
line; it is clothed with whitish hairs, and its colour is very pale, yellowish-brown, with a 
broad, brownish-black band on each side, nearly parallel with the lateral margin, and another 
of the same hue extending along the middle, which increases in breadth as it approaches the 
eyes. The falces are short, strong, conical, vertical, and armed with teeth on the inner sur¬ 
face ; their colour is pale, yellowish-brown, with the exception of the extremity, which has a 
brownish-black tint. The maxillae are straight, powerful, and greatly enlarged at the 
extremity, which is rounded; the lip is semicircular, but somewhat pointed at the apex. 
The colour of these parts is black, the apices having a yellowish-brown hue. The sternum 
is heart-shaped, and has prominences on the sides, opposite to the legs; it has a black tint, 
with a small, yellowish streak in the middle of the anterior part. The legs are robust, pro¬ 
vided with hairs and numerous erect spines, and of a yellowish-white or very pale, yellowish- 
brown colour, with brownish-black annuli; the tarsi, in addition to the three claws of the 
usual structure by which they are terminated, have several smaller ones situated below them. 
The palpi resemble the legs in colour, and have a curved, pectinated claw at their extremity. 
The abdomen is large, of a subglobose form, projecting over the base of the cephalo-thorax; 
the upper part is of a greenish-yellow hue; four oval, white spots, conspicuous in the anterior 
region, form a trapezoid, whose anterior side is the shortest, and from the outer extremity of 
each of the posterior spots a white, sinuous line extends to the spinners; along the medial 
line there is a series of white streaks and spots, and from the anterior streak, which is the 
longest, several white spots pass to the sides, and are succeeded by some faint, oblique dashes 
of white ; the sides and under part are of an orange-browm colour, a broad, longitudinal band 
of a deeper shade, obscurely bordered with yellow anteriorly, occurring in the middle of the 
latter ; the sexual organs have a curved, wrinkled, taper, membraneous process connected 
with their anterior part and directed backwards ; its colour, and that of the branchial 
opercula, is’ dark-brown, the inner margin of the latter being paler. Individuals of this 
species vary in colour from pale, greenish-yellow to dark, orange-brown, but the four oval,
