Show 730 REV. O. P. CAMBRIDGE ON NEW ARANEIDEA. [NOV. 1, An immature male (owing to the greater length of the abdomen) measured 3| lines in length. The cephalothorax has the upper marginal profile line, of both the caput and thorax, level; the normal indentations are strong and form the emarginate appearance of the lateral edges ; its colour is a bright orange-red; it is thickly impressed with minute punctures, and furnished thinly with fine greyish hairs. The eyes are eight in number; the two outer ones of each row are contiguous to each other, and thus the eight form four pairs occupying the four corners of the ocular area ; the two central eyes of the hinder row are the largest of the eight; they are of an oval shape, grey in colour, and separated from each other by the space of an eye's diameter ; the two fore centrals are next in size, round in form, dark-coloured, and not more than half an eye's diameter apart from each other; the four lateral eyes are the smallest, nearly equal in size, and of a pearly white lustre ; the height of the clypeus (i. e. the space between the lower margin of the fore central eyes and the insertion of the falces) is rather more than the diameter of one of those eyes. Legs: those of the first and second pairs are much the strongest (especially the coxal and femoral joints); their colour is orange-yellow, and they are furnished only with fine hairs. Palpi short, similar in colour and armature to the legs; humeral joints much bent; cubital and radial joints short, about equal in length and strength; the latter (radials) are very slightly produced in a pointed form at their outer extremities ; the digital joint is rather large, suffused with a brownish hue, and of an oval form. The palpal organs are neither very prominent nor complex; they consist of simple corneous lobes or processes, with a rather strongish prominent point near their centre. Falces moderately long, not very strong; they are of a conical form, vertical in position, and furnished at their extremities with a weakish curved fang ; their colour, together with that of the maxillee and labium, is similar to the colour of the cephalothorax. Sternum oval, with indented margins, and with a small, narrow, somewhat oblong production at its hinder extremity ; in colour it is similar to the maxillae and labium. Abdomen long, narrow-oval in form, and moderately convex above ; it is of a warm pinkish-red colour, and rather thickly clothed with short hairs of a dull brownish yellow ; an apparent pedicle, which, however, is only the prolongation of the hinder extremity of the cephalothorax, connects it with that part; the spiracular plates are yellow, and the spinners two only. An adult and an immature male of this species were contained in a collection of Spiders most kindly made forme in Bombay, in 1863, by Captain (now Major) Julian Hobson (of H.M. Staff Corps), after whom I have great pleasure in naming it. It is a remarkable Spider, not only from the form of the cephalothorax, maxillae, labium, and position of the eyes, but especially from the possession of but two spinners, in which, as also in the form of the maxillae and the |
