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 arma- 

 ture 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 f alces 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 maxillae 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 con- 

 necting 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.

An adult male and female, besides immature examples of both 

 sexes, were found under stones near the pyramid of Ghizeh.

This Spider is very similar in size, general form, structure, 

 colours and markings to G. conspersa, but may be readily dis- 

 tinguished 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.
