 4, 1, 3, 2, or 4, 1, 2, 3, or 4, 1, 2-3; they are of a brownish yellow colour, deeper on their fore-sides, furnished with hairs, bristles, and spines, the latter not very numerous nor unusually strong; there are no spines on the outer sides of the genual joints of the third pair; the tarsal claws are longish and strong. Those of the superior pair have but one, two, or three pectinations on their underside; on some of the legs I could not detect any. There seemed to be no more uniformity in the tarsal-claw pectinations in this species than in others. The tarsal and metatarsal joints of the legs of the first pair have a fringe of close-set short blackish hairs on either side, as also have the digital joints of the palpi, these being similar to the legs in colour and armature; the humeral joints are very deep but narrow, being apparently bent and hollowed on their inner sides to allow of meeting well over the falces.

The terminal palpal claw has two teeth towards its base on the underside. I could not ascertain satisfactorily whether this is or not a uniform character in all examples; in one example these denticulations were very plain, but they seemed to be wanting in others.

The falces are very strong and massive, round in their profile, and very roundly prominent near their base on the upper side. They are of a rich deep black-brown colour, glossy, and furnished along their inner margins with black bristles and hairs, and with strong spines at their extremity on the upper side. The fang is strong, and the outer margin of the groove in which it lies when at rest has some strong teeth.
