each tarsus terminates with two curved pectinated claws, beneath 

 which is a small claw-tuft. 



The palpi are short and rather strong ; the radial is rather 

 shorter than the cubital joint, and has its outer extremity produced 

 into a strong, broad, red-brown apophysis, from the upperside of 

 which springs an almost perpendicular conical projection with a 

 small, rather sudden, sharp, curved, corneous point at its extre- 

 mity ; the palpal organs are well developed, prominent, but not 

 very complex, with a strongish curved corneous process at their 

 extremity. 



The falces are rather long, strong, and conical ; and a little pro- 

 minent near their base in front. The maxillce are strong, consider- 

 ably curved, and inclined strongly over the labium, and are also 

 broadly impressed in a transverse direction. 



The labium is oblong, broader at the base than at the apex, 

 which is rather squarely truncated ; these parts are of a dark reddish- 

 brown colour, the maxillae being dull yellowish white at their ex- 

 tremities. The sternum is large, heart-shaped, and of a yellow- 

 brown colour, the centre being strongly suffused with blackish. 



The abdomen is of an oblong-oval form, and of a dull brownish- 

 yellow colour, clothed with short fine grey and yellowish hairs ; in 

 the central line of the fore part of the upperside there is a 

 strong oblong black-brownish patch, followed behind by a close 

 series of strongish angulated blackish bars or chevrons, which have 

 a tendency to become confluent, but do not extend to the spinners, 

 round which are two or three blackish spots ; the sides are marked 

 irregularly with blackish brown, and the underside has two parallel 

 longitudinal black-brown lines throughout the greater part of its 

 length : the spinners are rather long and prominent ; those of the 

 inferior pair are the strongest and generally longest, and of a dark 

 blackish-brown colour, the rest being of a dull whitish yellow. 



The female resembles the male, but is larger ; the genital open- 

 ing is simple, being of a transverse somewhat oval form margined 

 with red-brown, and has a somewhat triangular space within it; 

 the palpi of the female end with a curved black pectinated claw. 



Adults of both sexes were found beneath stones on the plains of 

 the Jordan, near Jericho.

Male adult, length 3 lines. 



In form and general structure, as well as in the position of the 

 eyes, this species nearly resembles G. ripariensis, but it may be 

 distinguished at once by its generally lighter colour and yellower 

 ground, as well as by the structure of the palpi and palpal organs. 

 The whole of the fore part, including the legs and palpi, is of a 

 yellowish colour; the cephalothorax has a narrow black marginal line; 

 and some small blackish markings indicate the junction of the caput, 

 thorax, and thoracic segments ; and the whole is clothed with a 

 short grey pubescence. The legs are moderately long and strong; 

 their relative length is 4, 1, 2, 3, and they are furnished with hairs
