[June 2, same colour), whose angles are obsolete, the ends of the bars only remaining ; the sides are also marked with a few short irregular similarly coloured lines and spots ; on either side of the longitudinal bar on the fore half are three small but conspicuous reddish-brown spots, forming a slightly curved line. The spinners are long and cylindrical; those of the inferior pair slightly curved, longest, and strongest; those of the superior pair 2-jointed. The form of the cephalothorax is more elongate than in Cheiracanthium generally ; it is oval, with the lateral constriction at the caput very slight, and the fore part moderately narrow; the normal grooves and indentations are marked by dusky converging lines. The eyes are of moderate size, in two transverse curved rows, the eyes of each of which respectively are equidistant from each other ; the four central eyes form a quadrangular figure, whose hinder side is rather the longest; the eyes of each lateral pair are placed obliquely but are not contiguous to each other. The clypeus appears to be about equal in height to the diameter of one of the fore central eyes. The legs are moderately long and tolerably strong; their relative length is 1, 4, 2, 3 ; and the genual joints are longer than usual; they are furnished very sparingly with hairs and a few spines ; each tarsus ends with two curved pectinated claws, beneath which is a very small claw-tuft. The palpi are not very long, but tolerably strong. The cubital and radial joints are about equal in length ; the latter is bent and has at its extremity on the outer side a rather prominent, slightly curved, tapering, sharp-pointed, red-brown, spine-like apophysis; and near the extremity on the inner side are two spines, one nearly upright, the other shorter but bent and directed forwards. The digital joint is dark yellow-brown, oval, pointed before, but not drawn out as in other species of this genus ; it is about equal to, or perhaps a little longer than the radial joint; the normal spur from the hinder part is obsolete, represented only by a slight prominence. The palpal organs consist of a principal oval lobe broken up at its fore part into several corneous processes, among which is a strongish one, somewhat in the form of an S crook. The falces are moderately long, tolerably strong, projecting and prominent towards their base in front. The maxilla are strong, of an oblong form, rather broadest at their extremities, straight but slightly inclined to the labium, which is half the length of the maxillae, and of a short, oblong-oval form. The sternum is of the ordinary heart-shape, with a slight eminence opposite the articulation of each pair of legs. A single adult male of this species was found by myself near Alexandria (Egypt), in April 1864. CHEIRACANTHIUM ECIUESTRE, sp. n. (Plate LII. fig. 29.) Adult male, length rather more than 2^ lines. The cephalothorax of this species is of a yellowish colour ; it is longer in proportion to its breadth than in many others of the genus, and the lateral constrictions of the caput are stronger, the caput |
