22 Mr. R. I. Pocock on some new 



angular prominence on the base of the tarsus, only a small 

 excrescence. 



Measurements in millimetres, — Total length 12 ; cara- 

 pace 5'5 ; first leg 29, second leg 30, third leg 32, fourth 

 leg 36-5. 



Loc. Brak Kloof, near Grahamstown (J//vs. White). 



Selenops Schonlandi, sp. n. (PL III. fig. 15.) 



Resembling S. atomarius, Sim., in having five pairs of 

 inferior tibial spines on the first and second pairs of legs *, 

 but much larger and with the eyes of the median quadrangle 

 less strongly recurved, the posterior medians one fourth larger 

 than the anterior medians, standing less than tlieir own 

 diameter above the clypeus, with their lower edge about on a 

 level with the centres of the latter ; the distance between the 

 anterior medians a little greater than their radius and a little 

 greater than the distance between the anterior and posterior 

 medians. 



Vulva consisting of a horny plate, marked on each side 

 posteriorly with a crest twisted like a ram's horn, and sepa- 

 rated by a median quadrate area which anteriorly expands 

 and is furnished with a right and left anguliform prominence. 

 ]n atomarius the crests are sinuous or lightly sigmoid, without 

 the strong ram's-horn curvature. 



Total length 16 millim.; carapace Q'b. 



Hah. Cape Colony, Jansenville [Dr. Schonland, type) and 

 Pearston [JJr. Broom~) ] Graaf Reinet [Miss Leppan). 



The British Museum has examples of S. atomarius from 

 Port Elizabeth [H. A. Spencer and Dr. Broom) and from 

 Brak Kloof, Grahamstown [Mrs. White). 



The African species of Selenops occurring south of the 

 Zambesi may be grouped as follows by the spine-armature of 

 their anterior legs : — 



A. Protarsi of first and second legs with 2 pairs 



of spines ; tibiae with 3 pairs radiutiis, Latr. 



B. Protarsi of first and second legs with 3 



pairs of spines. 



a. Tibise of first and second legs with 4 



pairs of spines parvulus, Poc. 



b. Tibiae of first and second legs with 5 



pairs of spines atomarius, Sim. ; Broomi, 



Poc. ; Scho'nlandi, sp. n. 



* In Ann. & Mag. Nat. Hist. (7) vii. p. 288 (1901), I forgetfully 

 assigned seven pairs of tibial spines to S. atomarius in comparing it with 

 *S. hasutus.
