South African Arachnida. 177 



inferior ones often partially or wholly smooth in segment 1 and in 

 the anterior part of segment 2 in both sexes ; the terminal tooth of 

 the superior crests in segments 1-3 and often also in segment 4, and 

 of the superior lateral crests in segments 1-2 and sometimes also in 

 segment 3, enlarged, stout and conical in the ? , slenderer and often 

 subspiniform in the 3^ ', the middle lateral crest strong and well 

 developed in segments 1-3, complete in segment 1, slightly ab- 

 breviated anteriorly in segment 2, still more so in segment 3, in 

 which it varies considerably in length, occupying from ^ to over I- 

 of the length of the segment, while in segment 4 it may be 

 completely absent or more or less distinct and weak, represented 

 by a row of larger granules, in a series of specimens from one and 

 the same locality. Anterior caudal segments finely granular above 

 but smooth below ; the sides of segments 1-4 and the under surface 

 of segments 3-4 generally finely granular (rarely almost smooth) in 

 the $ , but often quite smooth in the S between the keels ; upper 

 surface of segment 5 in the ? entirely smooth or granular laterall}^. 

 rarely also minutely granular mesially, in the ad. 3' finely and 

 densely granular throughout, except along the median line in the 

 anterior half ; the superior keels in segment 5 developed only in the 

 anterior -i— -J of the segment, the lateral surfaces densely and often 

 coarsely granular or the inferior part smooth or nearly so, the inferior 

 surface with coarse and fine granulation or the fine granulation 

 absent, the coarse granules generally forming irregular accessory 

 crests in the anterior half, the median crest generally distinct, rarely 

 obsolete. Vesicle granular throughout, or smooth below and granular 

 only on the sides and posteriorly below the aculeus, moderate or large 

 in the ? , smaller, rarely large, in the 3 . 



Pedipalps. — Upper surface of tibia generally smooth (sometimes 

 granular in the 3), the anterior edge of this surface generally well 

 defined and provided with a row or strip of granules ; the anterior- 

 surface of tibia granular above. Hand smooth, except distally 

 below, where it is frequently finely granular ; its greatest width 

 exceeding that of the tibia, especially in the 3 , the length of the 

 tibia 2-2^ times the width of the hand in ad. 3 ; movable finger in 

 the 3 short, provided at the base with a distinct or indistinct lobe,, 

 the immovable finger sinuate at the base ; fingers with 9 main rows 

 of teeth. 



Pectines with 19-26 (according to Pocock up to 27) teeth, the 

 basal tooth in the ? always similar to the rest of the teeth in all 

 our specimens, the scape longer in the 3 than in the ? but varying 

 in length according to locality.
