racter. The cephalothorax is of a pale yellow-brown, deepening 

 on the caput and clypeus ; the junctional lines of the caput, thorax, 

 and thoracic segments are indicated by dark converging lines. The 

 eyes are not very unequal in size, and are tolerably closely grouped 

 together ; those of the hind central pair are oblique, oval, and nearer 

 to each other than each is to the lateral on its side ; the front row is 

 a little shorter than the hinder one, and the eyes of its central pair 

 are further from each other than each is from the lateral on its side ; 

 those of each lateral pair are separated by an interval of less than the 

 diameter of the hinder one. The legs are rather short, but moder- 

 ately strong ; they are furnished with hairs and a few fine spines ; 

 their colour is yellow, those of the first and second pairs are a little 

 suffused with yellow-brown. The palpi are yellow-brown in colour. 

 The falces moderately long, strong, prominent at the base in front 

 and a little projecting ; their colour is deep red-brown. The maxilla 

 are of normal form and of a dark yellowish red-brown colour, but 

 lighter in hue than the falces. The labium is similar to the maxillae 

 in colour, of oblong form, rounded at the apex ; and the sternum is 

 yellow-brown. The abdomen is of an oblong-oval form, and its colour 

 dull yellowish ; on the upperside is a largish dusky brown elongate 

 wedge-shaped marking in the central longitudinal line of the fore 

 part ; this is followed, towards the spinners, by a series of indistinct 

 but broadish angular lines of the same hue. The genital aperture 

 is of a distinct and characteristic form, being a rather large and some- 

 what circular opening with a longitudinal septum whose margins are 

 strongly angular ; and below this are two round boss-like glossy but 

 slight prominences. 



A single adult female was found under a stone at Hebron.

The whole of the fore part of this Spider is yellow, the cephalo- 

 thorax being rather darker than the legs, and clothed with fine grey- 

 ish hairs. The cephalothorax is of ordi.iarv form but rather narrow 

 in front. The eyes are in two curved rows, the curves directed back- 

 wards ; the hinder row is more strongly curved than the front one ; 

 the eyes of the hind central pair, which appear to be the largest of 

 the eight, are separated by a slightly less interval than that between 

 each and the lateral eye on its side ; the interval between the fore 

 centrals is greater than that between each and the fore lateral on its 

 side, from which it is separated by a very small space ; the intervals 

 between the eyes of the hind central and those uf the fore central pair 

 are equal, but are less than that which separates each of the former 

 from the fore central opposite to it. The legs are rather sbort but 

 tolerably strong ; their colour is yellow and they are furnished with 

 hairs, and a few spines on those of the two hinder pairs. The falces 

 are small, vertical, and not prominent in front. The maxillce are of 

 normal form, and are strongly inclined to the labium. The sternum 

 is oval, pointed behind ; and its colour is yellow, narrowly margined 

 with red-brown ; and it is a little indented between the basal joints of
