the ocular area is broader than long, the line formed by tbe two 

 posterior eyes being considerably longer than that formed by the 

 four anterior ones ; the fore centrals are of a dull mother-of-pearl 

 colour, unusually large, but not quite contiguous to each other, and 

 each is also very near but not quite contiguous to the lateral of the 

 same row on its side. The minute eyes of the middle row are rather 

 nearer to the posterior than to the anterior row, and each is placed 

 within the straight line formed by the lateral eyes of those two rows 

 respectively. 



The legs are rather unequal in length ; those of the first pair (in 

 the male) are the longest and strongest ; the femora, genua, and 

 tibiae of this pair are of a bright yellow-brown, the metatarsi con- 

 siderably darker, and the tarsi pale yellow, the tibice and metatarsi 

 being fringed above and below with strong prominent hairs ; the legs 

 of the third pair are, in the males, next in length (in the females 

 they are rather longer than those of the first pair), those of the 

 second pair being a little shorter than those of the fourth ; these 

 three pairs are yellow, slightly marked with dusky brown, but not 

 regularly annulated ; all are furnished with spines, those beneath 

 the tibiae and metatarsi of the first pair being the longest and 

 strongest. 



The palpi are short, and yellow in colour, the radial and digital 

 joints bright yellow-brown ; they are furnished thickly with hairs, 

 chiefly white, and some of them, especially on the cubital, radial, 

 and digital joints long and strong ; the radial is rather shorter than 

 the cubital, and has its extremity on the outer side produced into a 

 very slightly curved, tolerably strong, tapering, deep-reddish-yellow- 

 brown apophysis, almost, if not quite, equal in length to the joint 

 itself ; the digital joint is oval, and as long if not rather longer 

 than the radial and cubital joints together; the palpal organs are 

 well-developed, but simple in structure, with a strong curved taper- 

 ing corneous process or spine lying along their inner side. 



The J alces are small, of a deep blackish reel-brown colour, and 

 clothed with white squamose hairs near their base in front. 



The maxillae and labium are similar to the falces in colour, tipped 

 with pale yellowish. 



The sternum is yellow, oval, and clothed with coarse whitish hairs. 



The abdomen is small, oval, blunt behind, truncate before, and 

 clothed pretty thickly with hairs ; its colour is sandy yellowish, 

 marked above and on the sides with dark brown, but forming no 

 very definite pattern ; the markings on the upperside are joined to the 

 lateral ones, and form somewhat oblique but irregular lines ; a central 

 dark marking along the middle of the fore half of the upperside is 

 also occasionally traceable ; the spinners are moderately long and 

 prominent. 



The female is larger than the male, and is of a generallv paler 

 hue ; the fore central eyes are also of a dull opaque whitish por- 

 celain hue. 



Two adults of each sex were found at the roots and among the 

 stems of scattered herbage on the desert near Gebel-y-Silsilis, in
