with no spines on its under, apical surface, but with 1 or 2 spiniforni 

 hairs. Tibia III with small anterior apical patch of spiuules. Comb 

 011 metatarsus IV composed of 6-7 spiniforni setae ; the patch of red 

 spinules on patella IV above extending over about ^ the surface.

Two $ 9 an d two $ 9 j v - specimens (No. 14611) from same 

 locality and collector differ markedly in appearance from the above, 

 both in colour and size (largest $ 32'5 mm., carapace 10'8 long, 

 9'6 wide). The eyes are different and spinatioii heavier than in 

 S. nanus.

Eyes. Anterior laterals broadly oval, prominent, only slightly 

 , inclined outwards from central axis, and narrowly separated from each

 and less than a radius distant from each other. Posterior row 

 procurved. Anterior laterals about an anterior median's diameter 

 from the latter. 



Sternum. Posterior sigilla small, almost circular, and slightly 

 more than their own diameter from border ; anterior sigilla similar 

 but smaller. 



Labium and coxae of pedipalps muticous. 



Chelicerae with 4 teeth on outer and inner row (one chelicera has 

 only 3, but larger, on outer side). 



Legs. Metatarsus I very slightly curved upwards in centre ; 1-2 

 apical spines below and 14-15 small, slightly curved spines down inner 

 side, and 14-16 longer ones down outer. Metatarsus II with 4 apical
