and the genital aperture, which, like that of all the species of this 

 genus and of most others also, is of peculiar and characteristic form 

 (vide Plate LI. fig. 3) and of a dark blackish red-brown colour ; 

 the spinners are of moderate length, those of the inferior pair being 

 strongest and slightly longest. 



A single adult female was found by myself in Egypt, among the 

 debris of an old wall, in 1864. 



Gnaphosa venatrix, sp. n. (Plate LI. fig. 4.) 



Adult male, length 2| lines. 



This species is very nearly allied both to G. marginata, G. corcy- 

 racea, and G. plumalis ; it is, however, smaller, and differs notably 

 in the form of the radial joint of the palpus, as well as in other 

 less prominent particulars. 



The cephalothorax is of a short oval form, pointed before and 

 very flattened above, of a yellow colour, clothed with greyish ad- 

 pressed hairs ; it is margined with blackish, and, besides a curved 

 blackish irregular line from inside each lateral eye of the hinder 

 row to the thoracic junction, the sides have some blackish mark- 

 ings between the normal converging indentations. 



The eyes are in the usual position ; but those of the hinder 

 row appeared to be very nearly equidistant from each other, each 

 one of the hind central (oblique-oval) eyes being nearer to the lateral 

 of the same row on its side than usual ; each of the fore central pair 

 seemed to be contiguous to the lateral of the same row on its side, 

 and the two (fore centrals) form a line equal in length to that 

 formed by the hind centrals. 



The legs are strong, moderately long, of a pale yellow colour, 

 furnished with hairs, bristles, and spines (the latter chiefly on those 

 of the two hinder pairs); the tarsi end with two slightly curved 

 pectinated claws ; but there appeared to be no scopula beneath 

 them ; the relative length of the legs is 4, 1, 2, 3. 



The palpi are short, strong, similar in colour to the legs, and 

 furnished with hairs and bristles ; the radial is about equal in length 

 to the cubital joint, and has its outer extremity produced into a 

 small, slightly curved, pointed apophysis ; the digital joint is large, 

 oval, pointed before, longer than the radial and cubital joints to- 

 gether ; the palpal organs are well developed, rather prominent 

 behind, and consist of several corneous processes and spines. 



Falces not very large, a little projecting, conical in form, and 

 ot a palish yellow-brown colour. 



Maxilla, labium, and sternum normal in form, and of a pale 

 yellow colour, furnished with hairs. 



Abdomen of a short oblong-oval form, and of a dusky drab colour, 

 marked above with short blackish lines, spots, and stria?, chiefly 

 towards the sides ; on the hinder half of the upperside is a longitu- 

 dinal series of transverse angular bars or chevrons of a clear pale 

 drab yellowish colour, divided from each other by blackish lines or 

 broken chevrons ; the underside has no markings. The spinners are 

 greatly unequal in size, those of the inferior pair being more than
