CAMBRIDGE ON NEW DRASSIDES. 387 such of the legs as were still uninjured were two, black and small; and beneath them is a scopula of short hairs extending backwards over the inferior surface of the joint. The palpi are strong and moderately long; the humeral joint is of unusual strength, being considerably prominent above towards its hinder extremity, lessening gradually forwards ; their colour is dusky yellow-brown. The radial joint is shorter and less strong than the cubital; it is furnished with numerous strong bristly hairs on its inner side, and has its outer extremity produced into a strongish apophysis, equal to the joint in length, rather enlarged and roundly obtuse at its extremity. The digital joint is large, and its length considerably exceeds that of the radial and cubital joints together. The palpal organs are large, highly developed, and very prominent, consisting of a large, nearly globular lobe with several dark sinuous markings on its surface, giving the appearance of closely applied spines; this lobe is rather drawn out at its fore extremity, where it is also apparently slightly cleft or divided. The falces are moderately long, rather slender, and nearly vertical; when looked at from in front, the maxillae are seen to extend considerably on either side of them; they are of a dark reddish-brown colour. Maxilla long and strong, and very slightly inclined towards the labium ; they are laterally prominent at their extremity on the outer side, and round on the inner side ; the outer profile-line, when looked at with the Spider flat upon its back, is hollow; the line and impression on their front surface is general, but not great. The labium is more than half the length of the maxilla?; it is oblong, rounded at the apex, and (with the maxillae) is of a deep yellow-brown colour. The sternum is of a rather elongate-oval form ; and its colour is yellow-brown, slightly tinged with reddish. The abdomen is oblong-oval, broadest and bluff behind and truncate before, where it projects over the base of the cephalothorax; it is hairy, and its colour is black. The fore half of the upperside is almost entirely occupied by a large patch of a deep reddish brown, shining, coriaceous nature; this patch is roundly pointed behind, its side margins being also rather rounding, and it lies exactly within a quadrangular figure occupying the largest portion of the fore part of the abdomen, and formed by four pale whitish spots: following the hinder pair of these spots, which are impressed and indicated by white hairs, are two others on the hinder half of the abdomen, rather nearer together, but also impressed, and shown by two short transverse lines of white hairs. The spinners are dusky black, not very long, those of the superior pair being very slightly shorter than those of the inferior pair, and not quite so strong: the spiracular plates are large, and of a clear pale yellow colour; between them the opening leading to the spermatic tubes is unusually visible and of a semicircular form; this opening is seldom visible in male Spiders, being usually an imperceptible slit. A single example of the adult male of this Spider was found among • |
