90 Annals of the South African Museum. 



Ocular area long, much longer than wide, and extending back- 

 wards to almost midway between its anterior margin and the middle 

 of the fovea ; its width subequal to the length of the metatarsus of 

 first leg. The area formed by the anterior lateral (frontal,) and 

 anterior median eyes wider in front than behind and very long, 

 about 3 times as long as its posterior width ; the median eyes 

 small, about their own diameter apart ; the lateral eyes much larger,. 

 very close together, and placed on a common tubercle, which is only 

 shallowly grooved along the middle above, the visual axis less hori- 

 zontal than in kolbei and spiricola. Posterior row of eyes with its 

 posterior margin slightly procurved, the median eyes distinctly 

 nearer to the laterals than to one another, the laterals large, about 

 as far from the anterior margin of carapace as from one another. 



Legs. First leg with the tibia as long as the metatarsus and of 

 the tarsus. Tibia of third kg with about 15 spines in the posterior 

 dorsal band. Legs otherwise much as in kolbei. 



Labium with 2 teeth. 



Total length 18 mm. ; length of carapace 5'8, width 4-9 ; length of 

 ocular area 1'9. 



Nest. The tube is short (4^- cm. in depth) and perfectly straight; 

 descending at a slight incline towards the hinge-side, as in Stasi- 

 mopus. It is cylindrical and w r ide in the deeper part, but becomes 

 narrower near the opening, which is only slightly oval. The lid is 

 flat and rather thin but not flexible, resembling that of kolbei, the 

 upper side being very rough and uneven, and the lower side smooth, 

 flat and lined with white silk. The edge of the lid closes against 

 the outspread rim of the tube-lining, as in the other species. 



Measurements in millimetres. Width of lid taken parallel to 

 hinge 14i and at right angles to hinge 12 mm. ; average thickness of 

 lid 1-J ; width of hinge 12| ; diameter of hole at 1 cm. from opening 

 9-10, near bottom 11. 



4. ACANTHODON VERSICOLOR n. sp. 



.l ? (No. 12001) found by Mr. D. L. Patrick on Baviaan 

 Kopje, three miles east of Umtali, Mashonaland, in June, 1902. 



5 . Colour. Carapace deep brown, paler mesially behind ; 

 chelicerse reddish black ; legs deep brown, the tibiae, metatarsi, and 

 tarsi of the 2 anterior pairs and the tibia and tarsus of the pedi- 

 palps reddish to reddish black, dark, especially at the sides ; femora 

 of all the legs and of the pedipalps with the under surface and the 

 sides pale yellowish, contrasting sharply with the dark brown colour
