Adult female, length 3| lines ; length of abdomen 2f lines; width of abdomen slightly less than the length; total width to extremity of the lateral projections very nearly 8 lines. Tbe whole of the Spider is of a dark rich reddish-yellow-brown colour, the sigilliform markings on the abdomen being a little darker than the rest. It is, however, quite possible that in life there might be other tints and colours now lost by age and desiccation. Although an unmistakably Gasteracanthid Spider, it seems to me impossible to include this remarkable form in any genus as yet characterized. Pound by Dr. A. R. Wallace at Sarawak many years ago, and obtained from the collection of the late Mr. Wilson Saunders. It is only lately that I have been able to ascertain (from Dr. Wallace) that he was the captor of this Spider, and in the locality mentioned. LABDACUS, Cambr. LABDACUS MONASTOIDES, Cambr. (Plate LII. fig. 3.) The female of this Spider (described and figured, P. Z. S. 1873, p. 118, pl. xii. fig. 3) was from Rio Grande, Brazil. The male now described resembles the female in general characters, colours, and markings. The length is 5| lines, that of the abdomen being 3f lines. Cephalothorax longer than broad, oval, truncated at each end; rather flattened above; profile-line to the posterior eyes level, excepting a slight depression at the thoracic junction; height of clypeus less than half the diameter of one of the fore-central eyes; lateral marginal impressions at tbe caput moderate. Colour brownish yellow, with a black marginal line and dusky converging bars. Eyes greatly unequal in size, in three widely separated groups, on black tubercular eminences. The lateral pairs with the hind-central pair form a transverse curved line, whose convexity is directed forwards. The hind-lateral eye is the largest and seated on the outside of a strong hemispherical prominence, at nearly an eye's diameter from the fore-lateral, which is the smallest and placed in front of the same eminence; the hind-centrals are nearly, if not quite, as large as the hind-laterals, they are rather more than a diameter's distance apart. The four centrals form a quadrilateral figure, whose length is greater than its breadth, and its anterior side much the shortest. Legs long, moderately strong, 1, 2, 4, 3 ; colour yellow; armed with spines, of which those beneath the tibiae and metatarsi of the first and second pairs are long, strong, and placed in a longitudinal series of 8 or 9 pairs beneath the tibiae, and 7 or 8 beneath the metatarsi; tarsal claws 3, springing from a small claw-joint. or* |
