Additional Notes. 



Specimens. A number of J $ and $ $ from localities on the 

 Cape Peninsula. 



The colouring of a g (No. B1123), which is probably newly 

 moulted, is as follows : Carapace ochraceous, with deep olive in- 

 fuscations in the cephalic region aud posterior carapace, and to a 

 less extent in lateral radiations from the fovea. Legs pale ochraceous 

 below, infuscated above on femora, and browner from patellae 

 onwards. Pedipalps lighter and tinged olivaceous ; abdomen infus- 

 cated above, with testaceous markings posteriorly, bringing out central 

 and oblique dark lines. Abdomen with its sides and under surface 

 pale testaceous with a distinct green tinge ; lung operculae and genital 

 plate darker and browner. 



Carapace. Fovea deep and slightly recurved. 



Eyes. Front row slightly procurved and equidistant; laterals 

 slightly larger than medians. Posterior row well recurved ; medians 

 subrotuud and not touching laterals, which are more oblique. 



Labiiim with 6-7 teeth ; chelicerae with 8-9, and an outer row of 

 minute denticles towards base of groove (2-3 deep basallyj. 



Pedipalps. As in Plate IX, fig. 4 A ; general position as in B and c. 

 The apparent difference is caused by contortion of the palpal organ 

 (it occurs in other specimens), whereby a different aspect is presented 

 from that usually seen.
