Cte&tjs spexceri, sp. n. (Plate III. figs. 9, 10.) 



d" . 18 mm. Ifab. King William's Town, S. Africa. Type in 

 coll. Brit. Mus. 



Total length 1.5 mm. Carap. 8 x 0. Legs : i. 31— ii. 28— iii. 24 

 — iv. 33. 



Carapace and legs pale nsahogany-brown, clothed with grey 

 pubescence. The former has a more conspicuous central grey 

 band and a broad marginal band, its inner margin being serrate 

 or scalloped. Abdomen with a dark shoulder-spot on each side 

 anteriorly, followed to the spinners by a double series of four 

 small pale spots, the first pair with a black ground. Ventral 

 surface pale rufous-brown, centre dusk)' with a series of four 

 broken silvery lines, sometimes 6, and a pair of epigynal silvery 

 spots. 



Tibia of palpus with a long narrow blunt spur, its apex 

 furnished with a short blunt cusp. Tarsus with a short sharp 

 basal spur, its apex directed upward and slightly outward. 

 Anterior central eyes much smaller and nearer together than the 

 posterior centrals. 



2 . Total length 23 mm. Carap. 9%3 x 7. Legs : i. 31— ii. 29— 

 iii. 26— iv. 34. Pat. + tib. i. 10-5— iii. 8— iv. 10-5. Prot. i. 6-5- 

 iii. 5-25- iv. 9. 



$ . Colour. Carapace dark brown, inclined to mahogany, with 

 central narrow band of dull ochre pubescence, attenuate between 

 eyes, dilate behind, again attenuate from central stria to base, and 

 a broader marginal band of the same colour. Legs clothed with 

 fine close ochre-yellow pubescence ; femora with spots of white 

 at base of spines above. Abdomen clothed with yellow-grey 

 pubescence, with central series of indistinct A-shaped pale blotches, 

 each branch having a dark spot at its apes. 



Ventral area inchned to black, with oblique lateral rows of 

 white spots, two short bars at genital rima, two broken lines between 

 these and the spinners in the centre, and on each side a longer, 

 more distinct broken line reaching to the spinners. Mandibles 

 unicolorous black, clothed with grey hairs. 



5 . Structure. Carapace horizontal, convex, scarcely gibbous 

 behind, abruptly inclined to base. Eyes. Second row straight, 

 line passing through centre of centrals touches posterior margin 

 of laterals. Centrals four times greater (by diameters) than 

 laterals ; k a diameter apart, ^ from laterals. Posterior laterals 

 ^ less than centrals, 1 diameter froL". centrals, | from lateral 

 anteriors. Ocular quadrangle much (almost twice) broader than 

 long, much narrower in front, width of anterior row less than 

 half the width of posterior row ; diameter of anteriors \ that of 

 posteriors ; the latter g a diameter apart, the same from posteriors. 

 Clypeus equal to one diameter of the anteriors. Spinulation of 

 legs similar to that of 0. occulentalis, except that tibia ii. has one.
