dark orange; coxae, legs, and palpi bright orange. Abdomen 

 above rough dark brown skin with fine yellowish ^ hairs ; the 

 underside paler with a small dark lunate stripe behind epigyne, 

 but no others. 



The cephalothorax is rather longer than broad, rounded at sides, 

 a deep thin fovea enlarged at each end, shallow corrugations 

 along each side of thoracic part. 



The eye-space is on a low flat quadrangle distinctly raised at the 

 rear as well as at the sides ; the rear row is clearly procurved, 

 the rearmost point of lateral eyes reaching only to a line passing 

 through the middle of the medians ; the eyes equidistant, equal in 

 size to one another and to the front median. These latter ai-e half 

 then- diameter apart and about half that distance from the laDei-als, 

 which are clearly larger than the median. 



There are only three teeth on lower edge of falx- sheath, the 

 foui'th, small one, of P. regina having disappeared. The epigyne 

 of the female is much squarer and more open at the base than in 

 the latter.

Pediana horni Hogg. 



Isopeda horni Hogg, Rep. Horn Exp. vol. ii. Zool. 1896, p. 340. 



The eyes of the front row are equal in size ; epigyne oval like 

 that of P. regina ; no spines on tibia iii. or iv. ; the front and rear 

 legs are set on rather straight. 



Loc. Oodnadatta, South Australia. 



Pediana tenuis, nov. sp. (Text-fig. 103.) 



This species more closely resembles the preceding ; they are 

 both larger and less brightly coloured than P. regina ; the eyes 

 are set on a similar raised space. 



The cephalothorax, legs, palpi, mandibles, sternum, lip, and 

 maxillae are all black-brown with pale brown hair. The undersides 

 of the femora of front two pairs of legs are bright red spotted with 

 black ; the abdomen above is yellowish grey, below reddish brown 

 hair ; a black transverse area behind the epigyne is rather deeper 

 than in P. horni, almost a short pointed shield. 



The eyes are bright orange ; those of the fi-ont row, on a plane
