to fourteen—short strong spines on the upper side of the extremity of the digital joint, furnished with hairs only. The cubital joint is more than half the length of the radial; this latter is equal in length to the humeral joint, and nearly as long as the femora of the first pair of legs. The digital joint is short, of an oblong oval form, broadest at its extremity. The palpal organs consist of a nearly spherical corneous lobe, prolonged at its fore extremity into a long, slender, tapering, beak-like spine, curving upwards (i.e., with its point near to the radial joint), and inwards.
A broad, conspicuous, shining, corneous band, of a deeper red-brown than the rest, runs round the middle (or equatorial line) of the spherical portion of these organs, covering the greater part of their surface.
The falces are of moderate length and strength, and of ordinary form. They are similar in colour to the legs, and furnished in front, chiefly on their inner edges, with hairs, and at their extremities on the inner sides, with a few, but not very strong nor conspicuous, short spines; their under side (along which the fang lies) is toothed on the inner edge only; the fang is strong and curved, but presents nothing remarkable in form, nor could I detect either denticulation or serration.
The maxillæ are strong, straight, divergent, with a small prominent point at the inner extremity of each; they are as strong, but not so long, as the basal (coxal) joints of the legs of the first pair, of a yellow-brown colour, furnished with hairs, but with no spines of any sort or size.
The labium is similar in colour to the maxillæ, and
