lower row are larger than the laterals, and each is further from the 
other than from the lateral on its side; the four form a curved line 
of less length than that formed by the two large eyes above them, 
from which they are separated by half a large eye’s diameter, and from 
the lower margin of the clypeus by rather more than that space. 
The legs are very long, moderately strong, and furnished with 
hairs, bristles, and long slender spines. Some of the legs were a good 
deal fractured ; but their relative length appeared to be 4, 3, 1, 2; 
those of the fourth pair greatly exceeded the rest, which did not 
seem to vary much in their relative length ; the femora were marked 
on the uppersides with stripes and irregular bands of brown. 
The palpi are short and moderate in strength; they are similar 
in colour and armature to the legs; the cubital joint is shorter but 
a little stronger than the radial; the digital joint is not large, it is 
about equal in length to the radial and cubital together, and it is of 
a yellow-brown colour ; the palpal organs are neither very prominent 
nor complex, they have a sharp projecting corneous prominence at 
their outer extremity. 
The mazille are not very long or strong ; but they incline towards 
the Zabium, which is broad, somewhat quadrate, rather narrower at 
its apex than at its base; its colour is yellow-brown, the apex sandy 
yellow. The s¢ernum is very short, heart-shaped, pointed. behind, 
and hollow on its fore margin. 
The abdomen is small and of an oval form; in the example 
described it was much shrunk and shrivelled; but it appeared to 
have an irregular dark yellow-brown longitudinal band on either side 
of the median line, leaving a broad central longitudinal strongly 
dentated yellow band terminating just above the spinners. 
An adult male of this Spider was obtained by Mr. Lord in a wady 
near Jebel Musa, Sinai. The length of the hinder pair of legs, and 
the constricted form of the cephalothorax, constitute very strong 
specific characters in this apparently hitherto undescribed species of 
a now numerous genus.
