each on the sides ; II. spined much as in I., except that the inner 

 row is composed of fewer spines than the outer ; III. with an anterior 

 row of 0-2 and 2 posterior rows of 2-4 spines each ; IV. unspined. 

 Patellce not spined. Femora I.-III. with a medio-dorsal row of 

 several spines and an outer distal row of 1-2 spines, I. also with an 

 inner distal group of 3-4 spines ; II. and III. with 1-2 inner distal 

 spines ; IV. unspined. 



Ghelicera with the lower tooth obsolete or scarcely distinguish- 

 able. 



Length of carapace and abdomen 5^-7^- mm. 



This is the smallest and at the same time the commonest of the 

 3 species found in the Cape Peninsula. In the apparently immature 

 specimens the legs are pale yellow, with much less or even scarcely 

 any infuscation, which is often limited to the tips of the segments of 

 the anterior legs. 



(b) 1 ? , with cocoon, from the Hottentots Holland Mountains 

 above Gordon's Bay (B. M. Lightfoot). 



(c) 3 2 2 from the Paarl (B. M. Lightfoot), with the sternum 

 darkened and with median yellow stripe. 



(d) 1 2 from Hermanuspetersfontein, Caledon Div. (B. M. 

 Lightfoot). 



(e) 2 ? ? from St. Helena Bay, Malmesbury Div. (J.E. C. Goold), 

 with the abdomen much more yellow than in the types. 



6. Ariadna karrooica, n. sp. 



Specimens.— (a) A ? (No. 12902) and a $ (No. 12845) from 

 Hanover and a 2 (No. 11963) from Eierfontein, 8-9 miles west of 

 Hanover (S. C. Gromvright Schreiner, 1901). 



2 2 {Types). Very like bilineata, but with stouter anterior 

 tibiae. 



Colour of carapace and legs as in the darkest specimens of 

 bilineata, but the anterior metatarsi dark reddish or almost black. 

 Abdomen pallid, more or less suffused with purplish, at least on the 

 dorsal and ventral surfaces, the middle of the epigastric area and 

 sometimes a couple of posterior ventral patches dark purplish. 

 Sternum and labium deep blackish -brown, the labium sometimes 

 paler at apex. 



Carapace as in bilineata, but the posterior row of eyes slightly 

 wider and with its hind margin forming a slightly procurved line 

 (seen from above). 



Legs like those of bilineata, except that the anterior tibiae are 

 thicker and more densely clothed with long dark brown hairs ; fourth
