bristles, the distal portion of the pedipalp and of the legs and the 

 under side of the abdomen thickly covered with longer, slender,, 

 apically notched, cylindrical bristles. 



GhelicercB with a number of apically notched or blunted spines on 

 the upper and outer surfaces, the long posterior ones of the upper 

 surface arranged in an oblique row ; distal part provided with long 

 slender bristles on each side, the dorsal surface with a long horizontal 

 distal bristle, which, rising close behind the insertion of the flagellum, 

 becomes gradually thinner towards the apex and is covered with very 

 minute spinules in its distal part. Upper finger strong, evenly 

 curved, with two large, pointed, distal teeth placed as far from the 

 apex as the distal tooth of the lower finger, and followed by a 

 rudimentary intermediate tooth, a large fourth tooth, and several 

 smaller teeth. Lower finger with two large pointed teeth and a very 

 minute intermediate one between them. 



Fig. 2. — B, namaquensis, n. sp. 



Flagellum lanceolate (seen from the side), the apex long and slen- 

 der, the opening on the inner side large, the basal part hollow, 

 gradually narrowing anteriorly, but not petiolate, rotatably attached 

 at the anterior end to the inner side of the upper finger behind the 

 level of the third large tooth of the single series ; the flagellum is 

 membranous and transparent, its surface is thickly studded with 

 minute prickles right up to the apex, and the lateral wall is furnished 

 along its middle with a thick, pale yellowish, longitudinal rib extend- 

 ing throughout the whole length. 



Gephalothorax with a few, very short, brown spines scattered 

 amongst the very numerous, short, cylindrical bristles ; the hind 

 margin, like that of the thoracic segments, with a row of longer 

 notched spines.
