Length of the female, §ths of an inch ; length of the cephalo-thorax, 1th, breadth, ith ; 
breadth of the abdomen, fths; length of an anterior leg, |ths; length of a leg of the third 
pair, 1. 
The cephalo-thorax is convex, clothed with pale yellowish-brown hairs, compressed 
before, truncated in front, rounded on the sides, and has a large indentation in the medial 
line ; it is of a pale yellowish-brown colour, with a fine, brown line on the margins, a broad, 
dark-brown band extending along each side and in front, and another, of the same hue, in 
the middle, which increases in breadth as it approaches the eyes. The four intermediate 
eyes are seated on a slight protuberance and nearly form a square, those of each lateral 
pair being placed obliquely on a tubercle and almost in contact. The falces are short, 
strong, conical, vertical, armed with teeth on the inner surface, and of a brownish-black 
colour, the extremity having a yellowish-brown hue. The maxillae are straight, powerful, 
and greatly enlarged at the extremity, which is rounded; the lip is nearly semicircular, but 
somewhat pointed; and the sternum is heart-shaped, with prominences on the margin, 
opposite to the legs and lip. These parts are of a blackish colour, with the exception of the 
extremities of the maxillae and lip, which have a yellow tint. The legs are robust, provided with 
hairs and numerous erect spines, and of a yellowish-brown colour, with dark-brown annuli; each 
tarsus is terminated by three claws of the usual structure, and below them there are several 
smaller ones. The palpi resemble the legs in colour, and have a curved, pectinated claw at 
their extremity. The abdomen is large, somewhat oviform, with a slight, obtuse, conical 
protuberance on each side of the anterior extremity of the upper part, sparingly clothed with 
hairs, convex above, and projects greatly over the base of the cephalo-thorax; on the upper 
part there is a brown, leaf-like mark, which decreases in breadth as it approaches the spinners, 
and has dark, sinuous margins finely bordered with white, and white spots in its anterior 
region ; it is bisected longitudinally by a line consisting of white or pale-yellow streaks and 
spots, which is intersected by three similar lines, giving it the form of a triple cross; on each 
side of the leaf-like mark there is a broad, sinuous, yellowish-brown band obscurely spotted 
with white; the sides and under part are of a dark-brown hue, mottled with dull 
yellowish-white, and along the middle of the latter there is a broad, brownish-black band, 
bordered anteriorly by two yellowish-white lines which are enlarged at their posterior 
extremity; a long, curved, wrinkled, membraneous, flesh-coloured process, directed back-
