The eyes are of tolerable size and in the usual position ; but the 

 curve of each row is nearly equal, making the two rows almost 

 parallel; the hinder row is the longest, and its two central eyes are 

 large, pearly white, and very nearly contiguous to each other, the 

 lateral on either side being separated from them by about the 

 diameter of one of the centrals ; the fore centrals are also large, but 

 not quite so large as the hind centrals, though forming a line of the 

 same length, the interval between them being rather more than 

 half of the diameter of one of them ; the eyes of each lateral 

 pair are separated from each other by an interval of about the 

 diameter of one of them. 



The falces are moderate in length and strength ; they are promi- 

 nent at their base in front, projecting forwards, and are of a dark 

 yellow-brown colour. 



The legs are rather short, moderately strong, furnished with 

 hairs and spines, the latter chiefly on the two hinder pairs ; their 

 relative length is 4, I, 2, 3, and they are of a yellow colour. 



The palpi are similar to the legs in colour, deepening to yellow- 

 brown on the radial and digital joints, and they are furnished with 

 hairs and a few black spines. 



The maxillae and labium are of normal form ; the former is yellow- 

 brown, the latter considerably darker. 



The sternum is oval, pointed behind, and similar in colour to the 

 cephalothorax. 



The abdomen is oval, rather truncate before, where it projects a 

 little over the base of the cephalothorax ; it is thinly clothed with 

 hairs, and of a dull brownish black hue, speckled and marked with 

 pale yellowish : on the upperside a dusky, elongate, tapering or 

 wedge-shaped marking occupies the central" longitudinal line of the 

 fore half: on either side of the hinder or pointed end of this 

 marking are two small, pale, elongate spots; and following it, 

 towards the spinners, in a longitudinal series, are 6 or 7 transverse 

 angular bars or chevrons of a pale dull yellow colour ; and the 

 vertex of each of these runs into the angle of the one preceding it. 

 The dark ground-colour of the abdomen is disposed in parallel striae 

 towards and on the sides ; and the intervals between the yellowish 

 angular bars themselves form dark broken chevrons. On the 

 underside are two longitudinal and rather pale yellowish lines, which 

 converge at a little distance from the spinners ; and at the extremity 

 of these lines on either side is a curved row of three round pale 

 yellowish spots, more distinct than the rest. The spinners are 

 moderate in length and strength, those of the inferior pair being the 

 longest, and their colour is similar to that of the legs. The genital 

 aperture is large and of peculiar form (vide Plate LII. fig. 24). 



A single adult female was found by myself at Cairo. 



Drassus pugnax, sp. n. (Plate LII. fig. 25.) 

 Adult male, length 3g lines. 



The cephalothorax of this species is short, oval, rather more 

 pointed before than in many others of the genus, but in other
