NEW SOUTH AFKICAN ARACHiNflDA. 689 



like opening along the middle, the edges of which remain 

 separate distally but fuse proximally (text-fig. 1). I'he distal 

 margin of the lamina is flattened out, and presents a foli- 

 .aceous concave extension on its outer side inferiorly — the side 

 .adjacent to the chelicera — the sides of this extension gi'aduall y 

 converging proxiinaHy into a slight keel which runs for a 

 short distiince along the outer surface of the lamina ventrally. 

 The dorsal margin of the flagelluin is slightly curved, and 

 ihas an acutely pointed termination : the ventral margin is 

 almost straight. The distal margins are for the most part 

 fringed with iiairs. The stridulatory area of the chelicera 

 presents seven longitudinal ridges. 



Ste mites. — Modified hairs are present on the third post- 

 genital steniite as numerous long stout rods, finely pointed at 

 .the apex ; there are roughly about twenty on each side, 

 .arranged irregularly and rather sparsely. In the neighbour- 

 hood of these hairs is a bright yellow exudate. Numerous 

 hairs of this kind, but more slender, are also found on the 

 first post-genital sternite. 



Measurements. — Total length 9 mm., length of flagellum 

 about 1'2 mm.

Stasimopus longipMl])is .sp. nor. PL XLYII, fig. 5. 



This species is founded on three ackilt male examples from 

 Kiinberley, collected by Bro. J. H. I'ower. 



Colour.- — -Carapace dark brown or pale brown; legs also 

 brown, the two anterior pairs and the palp being somewhat 

 darkei- than the hinder two pairs, except on the distal 

 portions of those appendages, which are pale. 



Carapace. — As long as the tibia of the palp, longer than 

 tibia I. I'he three keels do not reach back so far as the 

 fovea. The surface more or less liyhtly sculptured or 

 roughened throughout, being nowhere quite smooth. Anterior
