Purcell) ; colour and structure as in the types, except that the fifth 

 caudal segment is smooth above in the ^ ; length of fourth segment 

 in ^ nearly 2f, in J 2^ times as long as wide. Length 3- 38, $ 

 .38-5 ; length and width of fourth caudal segment <y 4-8, 1-7, 2 4-4, 2. 



(c) Three young specimens from round the village of Prince 

 Albert (W. F. Purcell). I also found several specimens of U. carinatus 

 inhabiting the same locality (see under (c), p. 178). 



There is very little diiference between the females of aZsto?«i and 

 karrooictis, although the males are easily separable. 



Uroplectes schlechteri, n. sp. 



5 . Colour pale yellow, the abdomen sometimes olivaceo- 

 ochraceous ; the three groups of eyes black ; the anterior, lateral 

 and often also the posterior margins of the cephalothorax and of 

 most of the tergites very finely blackened, but the tergal keels of 

 first 6 segments not blackened ; the inferior keels of posterior 

 caudal segments and the anterior f of fifth segment infuscated ; the 

 legs blackened along lower edges ; chelicerae with fine infuscate 

 reticulation. 



Cephalothorax finely granular, the posterior pair of crests distinct 

 or indistinct, the eye-tubercle smooth. 



Tergites and sternites as in carinatus. 



Tail long, the fourth segment 2-|- times as long as wide ; the crests 

 in segments 1-4 for the most part feebly denticulate, the infero- 

 medial, and for the most part also the infero-lateral keels smooth 

 in segment 1 ; middle lateral crest strongly abbreviated in segments 

 2-3, being present only in the posterior ^ or i in segment 2 and in 

 the posterior 3- or ^ in segment 3, wholly absent in segment 4 ; 

 upper surface of tail somewhat granular in anterior, smooth in 

 posterior segments ; the intercarinal surfaces on the sides and below 

 almost entirely smooth in segments 1-4, except between the superior 

 and upper lateral crests in segment 1 ; segment 5 almost smooth, or 

 with a few weak granules on the sides, the under surface with the 

 usual 3 finely denticulate keels, the surfaces between these keels with 

 an irregular series of coarser remote granules along the middle on 

 each side ; vesicle weakly and sparsely granular below. 



Legs sparsely granular or nearly smooth externally. 



Pedipalps. — Femur mooth above. Tibia smooth above, its upper 

 surface with the anterior border sharply marked and granular, its 

 length 2|— 3 times the width of the hand. Hand slightly exceeding 

 or almost equalling tibia in width.
