Show 550 REV. O. P. CAMBRIDGE ON EGYPTIAN SPIDERS. [June 20, tiguous to its fore lateral eye ; the interval between the fore laterals is equal to very nearly two diameters ; those of each lateral pair are placed obliquely, and are rather smaller than those of the central pair. The legs are rather long and slender, except the femoral joints ; their relative length appears to be 4, 1, 2, 3. Whatever their armature may have been, it was entirely rubbed off before this description was prepared. The palpi are rather long, slender, and similar in colour to the legs ; the digital joint is cylindrical and exceeds in length the radial and cubital joints together. The falces are long, tolerably strong and straight, but strongly directed backwards to the labium ; and their front surface is thinly covered with minute, and probably pilose, reddish brown tubercles. The maxilla and labium are forced backwards into a direction perpendicular to the sternum, owing to the strong backward direction of the falces. Their form is thus very difficult to be ascertained, but it appears to be similar to that of the other species of this genus. The abdomen is short, oval in form, considerably convex above, and does not project over the base of the cephalothorax ; the connecting pedicle being distinct. Four spiracular springs are plainly visible, the two extra ones being placed not far behind the ordinary pair. The spinners are short; those of the inferior are much the strongest. A single example was found under a stone at Alexandria in April 1864. Fam. DRASSIDES. Gen. GNAPHOSA, Latr. CtNAPHOSA PLTJMALIS. Gnaphosa plumalis, Cambr. Proc. Zool. Soc. 1872, p. 225, pl.xv. fig. 3. An adult male of this Spider was found under a stone at Alexandria. GNAPHOSA CONSPERSA. Gnaphosa conspersa, Cambr. Proc. Zool. Soc. 1872, p. 230. pl. xv. fig. 5. An adult male and female, besides immature examples of both sexes, were found under stones near the pyramid of Ghizeh. GNAPHOSA PROCERA. Gnaphosa procera, Cambr. Proc. Zool. Soc. 1874, p. 373, pl. i. fig. 2. This Spider is very similar in size, general form, structure, colours and markings to G. conspersa, but may be readily distinguished by the special form and structure of the palpi and palpal organs ; examples of both sexes in the adult state were found under stones near Alexandria. |
