1 male and 3 females. 



Collected from Spain and Africa ; also, according to various 

 authorities, round the world eastwards and, according to F. 0. P.. 

 Cambridge, in S. America. 



It is impossible to compare Doleschall's drawing of S. culi^ 

 civorus with a recognised female specimen of P. payktdli without 

 feeling that it must have been drawn from the same, and Thorell 

 apparently arrived at this conclusion (Eagni Indo-Mal. 1892,. 

 p. 370). In his description, which is quite short, Dr. Doleschall 

 says that the legs are in the order 4 3 2 1, while it is certain that 

 the second pair is the shortest. 



The patella and tibia iii. are of the same length as patella and 

 tibia iv,, and the rear row of eyes in the female is slightly shorter 

 than the first row, while in the male it is quite clearly so. 



Von Keyserling gives an excellent drawing of the male and! 

 adds what he says is the epigyne of the female ; the latter, how- 

 ever, is quite unlike those of specimens in the British Museum 

 (Natural History), which resemble the above. (See text-fig. 5, /.)

1 male. 



This male seems clearly to belong to this species, agreeing 

 with Thorell's elaborate description, and showing the first pair 

 of legs longest, though not so long in proportion as in some later 

 described species. The mandibular tooth on the inner margin is 

 conical and quite large if the soft basal portion is taken into 

 consideration, and only "very minute" if you reckon the point 

 alone, which is darker and harder. The mandibles are hollowed 

 out in the middle of the inner side, much corrugated, and the 

 stout base of the short curved fang occupies the whole of the 

 anterior end of the falx. 



A raised flat rim at the front of the clypeus seems a feature in 

 this genus Zenodorus ; it is not quite so well defined in the female 

 as in the male.
