Specimens have also been obtained from the following localities : 

 7 ? ? and juv. <J (No. B 1633), Beaufort West (Dr. W. F. Purcell, 

 10/05); 2 sub-adult ? ? (No. 3938), Beaufort West (Dr. W. F. 

 Pure-oil, 9/96); 2 $ ? (No. 14250), Touws E. (J. Paynter, 12/04) ; 

 1 ? (No. 3965), Touws E. (Dr. W. F. Purcell, 9/96) ; 1 ? and sub- 

 adult (No. B2467), Matjesfontein (Dr. W. F. Purcell, 8/03) ; 1 ? and 

 juv. (No. 8920), Moordenaars Karroo, Sutherland Div. (J. Meiring, 

 19(10) ; 1 $ and juv. (No. 13698), Prince Albert (E. Broom, 1904) ; 

 1 ? and juv. (No. 3685), Steinkopf, Namaqualand Div. (W. H. Turle, 

 1/97) ; 2 sub-adult ? ? and 1 sub-adult (No. 12862), Laingsburg (Dr. 

 W. F. Purcell and E. M. Lightfoot) ; 3 ? ? and 5 juv. (B 1633), 

 Beaufort West (Dr. W. F. Purcell, 24/10/15). Four $ ? and 6 juv. 

 specimens from Matroosberg at an altitude of 3500-4000 ft. (E. W. 

 Tucker, 15/1/17), offer slight differences from the above description, 

 in that the median plate of the vulva is smaller, more oval, and 

 completely surrounded by the dark raised border; the breadth of the 

 carapace is ;ils> slightly greater than the length. These differences, 

 which are also shown in Nos. 13698 and B 2467, do not, however, seem 

 to be markedly specific.

fns. Numerous ? $ taken on the Percy Sladen Trust 

 Expedition to South-West Africa (localities at end) in December, 

 1915, and Januiry, 1916 (E. W. Tucker, coll.). Types, B2703. 



The specimens, of which 34 were taken, are all ? $ , and range from 

 juveniles to old a.dults, and all appear referable to one species. This 

 has been described as new, though owing to the diagnoses of other 

 species being based mainly 011 colour and markings, both U. guinque- 

 nutalu (Sim.) and U. schinzi (Sim.) and possibly U. semilimbata 

 (Sim.) might be represented by various stages and variations in the 

 specimens 1o hand. From this material it appears that the testaceous 

 spots are prominent in the young and tend to disappear in the adults ; 

 though the range of variation is such that they may be retained in 

 adult forms, and even reinforced by testaceous flecks until the spots 

 are linked in an irregular chain. Also almost melanic varieties occur, 

 the upper abdomen lacking testaceous, spots or flecks ; the opposite
