The occiput, which is paler than the rest, is clothed with greyish hairs, of which some in the centre are quite white ; there is also a patch of white hairs behind each of the large fore central eyes, a smaller one almost in a line between the posterior pair of eyes, with a few similar hairs round these last. The thorax has a narrow lateral submarginal band (on each side) of white hairs; and a dense row of similar hairs projects prominently forwards just above the lower margin of the clypeus. The legs are yellow-brown, those of the first pair, excepting the tjrsi and metatarsi, much the darkest; the others are obscurely annulated with dark yellow-brown. The spines (on the first two pairs) are 4 (in two pairs) beneath the metatarsi (these are the strongest), and 6 (in three pairs) beneath the tibiae. On the third and fourth pairs of legs the spines are more numerous, but less strong and more irregularly placed. The palpi are moderately long; the cubital joint is of a clavate form, double the length of the radial, and has some whitish hairs on its anterior surface. The radial joint has a strong, but short, obtuse prominence behind, and a curved, shining, tapering, sharp-pointed apophysis on its outer side. The digital joint is of moderate size (but longer than the cubital), and of an oval form ; the palpal organs are simple, not very prominent, and (apparently) closely surrounded with a strong black spine. The falces, maxilla, labium, and sternum are yellow-brown ; the falces are the darkest, and have, at their extremities on the inner side, two short parallel rows of small but distinct denticulations, within which the fang lies when at rest. The abdomen is dark brownish black, varying to deep brown in parts ; on the upperside two large, somewhat crescent-shaped paler markings occupy each side of the anterior portion, and are clothed with shining white hairs ; these are obliquely crossed at their hinder ends by a similarly clothed pale stripe, thus giving the appearance of a tolerably perfect large white circle occupying the whole fore half of the upperside of the abdomen ; the posterior half is marked with several ordinary pale angular bars or chevrons, thickly clothed with whitish hairs. The sides and underside are pale dull yellowish brown, tbe former obscurely and obliquely marked with dark brown. The spinners are small, but of tolerable and equal length and prominent. A single example, but in very perfect condition, was received in Mr. Traill's Amazon collection. List of Spiders described. Xeropigo (g. n.) tridentiger, Cambr., St. Helena, p. 424, Pl. XXIX. fig.
