PICKARD-CAMBRIDGE ON [^P1*- 18> The eyes are small; those of the central quadrangle form nearly a square, the anterior side a little longer than the posterior ; the fore-lateral eye on each side is equidistant from the fore and hind central eyes on its side; the hind-lateral eyes are far removed backward's from the fore-laterals ; the fore-centrals appear to be a little the largest. The legs are moderate in length and strength, 1-2-4-3, very little difference between 1 and 2. Colour yellowish brown, the femora of the first and second pairs bright orange-reddish ; the tibiae and metatarsi less bright, curved, furnished with spines ; these are numerous as well as strong (though not very long), especially in front and on the inner sides of the tibiae and metatarsi of the first and second pairs, the tarsi aud the anterior portion of the metatarsi of which are suffused with dark brown. The hairs on the fore parts of the anterior tibiae and metatarsi are coarse and grey. Palpi similar to the legs in colour and armature. Falces long, strong, pale brownish yellow. Maxillce, labium, and sternum pale yellow-brown, the last furnished with strong bristly hairs. Abdomen large, the fore part (continuing the line of the hinder part in an even run) is greatly elevated, and a little tapering to a slightly enlarged part on the outer sides, rather in front of the top of which are six small prominences, three in a longitudinal line on each side; from this point there is a further but less strong production enlarging at its extremity which is bifid, being divided into two obtuse, rounded prominences. Colour yellow-brown, clothed with short grey and other hairs, and marked on the sides and hinder part with small black-brown spots, some forming on tbe sides obscure oblique lines ; on the hinder part (looked at from behind) are two large, somewhat oblong or irregularly oval, deep rich bottle-greenish velvety markings in a longitudinal line ; the hinder one of these markings is the largest, and both are narrowly edged, with first a blackish, and then, outside (in the preserved specimen), a dull golden line. This very remarkable Spider is nearly allied to a Zanzibar species, P. furcifer Sim.1, but differs in the form and markings of the abdominal elevation. From a note received from its captor, it seems that this Spider has faded somewhat since it was placed in spirit, as he speaks of the "head, thorax, and adjacent sides of the legs being of an orange-red colour," and the bordering line of the green patches on the abdomen as pink.
